Distributors and suppliers[edit]

It has been suggested that [[::Supplier Quick Reference|Supplier Quick Reference]] be merged into this page or section. (Discuss)

russ_hensel I propose to reorganize this a bit by alphabetizing the suppliers withing category and moving comments about individual suppliers to that supplier .. register objections in the next few days, silence will be taken as consent, ok? ... In reverse alphabetical order, Z to A.

Even if you can find the perfect part, sometimes you can't find anyone who is willing to sell you one. Here is some information on component suppliers.

Giant Catalogs[edit]

Digikey Digikey Mouser Mouser Farnell Farnell


These guys have huge catalogs and an immense selection of parts, yet are still willing to sell things in onseies-and-twosies to hobbyists who can't claim to be prototyping something that'll sell a million units next year. Digi-Key actually got its start in the ham radio market, selling digital keyers.

I (Wiml) find that Digi-Key is the place to go for digital stuff, microcontrollers, and the like. For discretes and analog parts, Mouser is usually cheaper and has a better selection. Neither company has a minimum order, but of course they do have shipping and handling fees which make small orders impractical.

I, myself (who?) appear to have found that Jameco is good for small quantities of a fairly common part.

I called up Digi-Key to see if I could alter an order I had just placed before it got fulfilled. My order was already far enough along that they couldn't stop it. I believe the phrase was "too far gone". That speaks well of their order fulfillment process. I hear Mouser should be in there too, but I've never had a compelling reason to use them.







Mid-size Suppliers[edit]

Allied Electronics[edit] Allied Electronics Honestly I'm not sure if this is a mid-size or large distributor (how are we to tell, anyway?) Allied tends to deal more with "heavy duty" electrical parts (wiring, relays, electromechanical, etc. . .) rather than electronics. However, I've noticed that they do have some suppliers that Mouser/DigiKey don't have in terms of electronics components.

BG Micro[edit]

BG Micro has been around for a long time. Some good deals on used surplus equipment.

Galco Industrial Electronics[edit] Galco Industrial Electronics Galco no longer offers a paper catalog, but all of their products can be found online in their web catalog. Really not sure if this would fall under small/niche suppliers or Mid-sized, but the selection and prices are really good...and you get a candy bar with every order :)

Jameco[edit] Jameco 's catalogs have been getting fatter recently and their prices are good for common parts. Their Jameco ValueBrand parts are often much cheaper than the competition. (I have yet to notice the difference, personally -mdwebster) Jameco tends to focus on generic and older parts, where the giant supplier tend to focus on newer brand name parts. Jameco has a decent selection of cheap tools.

For those living in the San Francisco bay area, particularly on the peninsula, Jameco has a will-call option. You can specify it when you choose shipping and then pick up the parts yourself in an hour or two, avoiding shipping charges. They are located just off highway 101 in Belmont, CA. You can also just drop in without placing an order first, and they'll pull they parts while you wait. Very convenient, if you happen to live nearby.

JDR Microdevices[edit]

JDR Microdevices has been around for a long time. They seem to be trying to get rid of the last few ICs and prototyping tools they have in stock and switching to desktop PC subassemblies.[edit] It's your trusted electronic components sourcing channel from China.

Newark[edit] Newark My most recent "Newark in one" catalog is even thicker than my most recent Digikey catalog. (The "in one" motto and the swirly logo look identical to the Farnell logo. Is there some kind of connection?)

Newark usually has just about every odd semiconductor you might need in stock. Their shipping tends to be rather expensive, however (be prepared, as they won't give you a shipping quote until after you order, just like every other distributor), and they seem to really not like small orders, in my experience.

Newark InOne, Farnell InOne, and MCM InOne are all electronics distributors owned by the InOne Company.


Pricewatch is good for locating certain computer gear at its version of the best price. Froogle is sort of the same thing, but without the seedy side filtered out.

Radio Shack[edit]

Radio Shack is OK if you need a common part NOW, but expect to pay probably 10 times the mail order price. In the past couple of years (2005-2006), I've noticed many Radio Shacks have ceased carrying ANY electronics parts. You're most likely to find solder, wire, switches, led's, and project boxes. The selection of transistors or IC's are poor to nonexistent. If you have a Fry's in your area, they have a much better selection, but their component prices are not much better then RS. Unless you need a part immediately, you'll be much better off getting it mail order. In late 2011 Radio Shack started to again expand their DIY electronics section by adding a few products from Arduino, further expansion is plann

Apex Electronics[edit] (in New Zealand)

Chipdatas Electronic Components[edit]

Chipdatas Electronic Components This‘s a website that distributes electronic components from China. They also sell their products on eBay. Their prices are comparable to other Chinese websites.

Smaller and niche suppliers[edit]

Happy LED Light ( Shop the best prices on large selection of LED light bulbs, LED spotlights, LED strip, LED tube, LED downlight, LED flood light & accessories.

Anykits ( Large variety of kits for motor control, audio & lighting control, timers, RF modules, protocol/sensor interfaces etc..very very budget friendly :)And the kits are amazing in quality. Received warning from Google that this site contains malware.

Action Electronics ( Good place for soldering suppies, hand tools, small components.[NOTE: Unfortunately out of business, checked on 10/16/2010]

Adafruit Industries ( DIY kits and AVR programmers. Their open source AVR programmer usbtinyusb is especially recommended. Ok service and shipping. LadyAda has be active int the TV begone and Cell Phone begone community uprising.

All Electronics ( Corp. needs to even out their stuff a bit. Either specialize in a few types of parts or be more even across the board. Spark Fun Electronics appears to be trying to do it right. It is still weird that I can't just order a bunch of 0603 resistors from them. Seems like a no-brainer.

Alltronics ( is similar to All Electronics in what they carry. Fairly sure they're different companies with annoyingly similar names.

American Science and Surplus ( has a little bit of everything. Rubber spiders, speakers, prisms, lab equipment, electromechanical timers, Slinkies, motors, switches, fake vomit, glow-in-the-dark pencils, radio-controlled toy rats... Good selection of fans and motors, and an oddball attitude to boot. If you're near Chicago, their retail store is even weirder. American Science & Surplus seems to have good prices on breadboards.

Avnet ( Huge selection, but not really aimed at the hobbyist market.

dipmicro electronics ( Parts, chips, microcontrollers, etc. Ship from Niagara Falls, Canada.

Electronics Goldmine ( is another surplus warehouse. Don't expect to find any particular part, but they have good prices on what they do carry.

Fastcomponents ( They only have packs, but the packs are good value. ( I've been very happy with Futurlec. Their prices are outstanding, especially on value packs. Their customer service isn't stellar, but in the end they've always resolved any problems that I've had. They ship from Australia/Thailand, but their shipping prices are reasonable & the shipping is quick enough.

Logical Systems ( IC Programming addapters. Surface Mount to DIP, many more than I thought there were. ( - Large selection of development boards, programmers, debuggers for microcontroller projects. All major architectures ARM, 8051, PIC, Atmel AVR, TI MSP430, Freescale HC08, HC12, etc. Marlin P. Jones & Assoc, Inc. ( - prototyping tools, components, motors, switches. Not a huge selection, but prices are low. If you order something that comes with an instruction sheet that was translated into English, the directions may be hard to decipher due to poor translation, possibly from Chinese. They ship from Florida.

Breadboard Depot ( ) - solderless breadboards, protoboards, copper clad boards, etching supplies, etc. (a division of MPJA ).

oddWires ( - Arduino Authorized Distributor, offers low-cost modules and component value packs. Section on Chip Amps too. Overall good prices.

Pololu ( - Specializes in robotics. Also offers a nice (low minimums) laser cutting / stencil service.

ProtoStack ( Stackable prototyping boards including standard breadboard layouts and microcontroller boards.

Saelig ( Test equipment, circuit modules, special-purpose chips. Target the engineering market more than the hobbyist/fanatic, nevertheless stock many affordable things.

Surplus Sales ( more exotic surplus parts.

Surplus Shed ( carries a some electronics and lots of optics. (Prisms, microscopes, etc)

Sparkfun ( Specializes in microcontrollers and robotics. They also have nice AVR tutorials.

TVI Electronics ( Manufacturer of intelligent LCD controllers for Optrex F-51320, F-51553, F-51852 and F-51854 displays, worldwide supplier of touch screens and touchscreen controllers.

West Florida Components ( Supplier of electronic components, parts and supplies. They have no minimum purchase requirement and their shipping is very reasonable ($3.50 for any order up to $15.00). Their selection seems to be growing from years past.

Wzmicro ( Provides low cost and high quality electronics components, hard to find and discontinued ICs and many other parts.

YourDuino Shop ( - Low-cost Arduino-compatible boards, Sensors, Output Devices, Robotics, Electronics Components

PCB manufacturers[edit]

For companies that supply a PCB customized to your design, see PCB Manufacturers.


I want to see some competition in the micro dev/app board market. I just paid approximately 34.95 + its share of the shipping for a 32 bit ARM microcontroller on a PCB and with a USB device port on one end and a series of header sockets on the other. If that is considered cheap, then this is never going to take off.

I realize that other authors will have different opinions than I, and that this entry is probably not going to remain as it is for long. Come on, everybody. These comments do not reflect the opinions of Open Circuits. They are only my own. Add yours.

I personally stay away from app boards unless I absolutely need to use them because of the price. Also the components tend to not be in sockets, so if you blow a pin or two on that $100 app board, you need to replace the entire board as opposed to a $5 microcontroller. Unfortunatly, many of the better parts are only available in SMT packages. Mzoran 15:30, 16 December 2007 (PST)

Competition? I see that there is a different 32 bit microcontroller on a PCB for $20 + shipping. It has a SMT microcontroller, but I see the same microcontroller is also available in a DIP package for easy solderless-breadboard prototyping. --DavidCary 22:51, 30 December 2007 (PST)

I've had great experiences with Mouser and Jameco for smallish orders (<$200). I've also had several good experiences with SparkFun. I now avoid Fry's. In addition to their horrible return policies, their stock is very random and prices aren't very good.

My personal experiance with Surplus Sales was very good. I would highly recommend them for anyone that needs a blower motor, hydraulic pump, etc. Good prices, good service.

See also the list at .

Don't forget to check ebay if you're looking for fairly generic items. There are a number of suppliers that ship cheap components from China, plus a few who ship from within the US. I've gotten great prices on character LCD displays, pin headers, SMD LEDs, and PIC microcontrollers, among others.

ledshoppe has good prices on LEDs (all pin-through-hole). They don't have any other components, but they do have dirt cheap bluetooth dongles and SD card readers that may be of interest. Shipped from China, shipping is free. Usually arrives in the US in about a week, never had a problem with them.

I'm not sure where this should go, but I find to be very useful for finding parts. You just enter a part number (or part of one) and it will do a real-time check with several suppliers including Mouser, Newark, Digi-Key and Jameco, and tell you who has it in stock and at what prices (in most cases - some suppliers just say "call for price"). This one site can save hours of shopping around. KeithHearn 17:48, 20 March 2008 (PDT)

Thank you, Keith. The Findchips website could save me a significant amount of time. The website is similar -- once you know the exact part number, it checks with several suppliers and tells you who has it in price and for what price. --DavidCary 20:49, 14 November 2009 (UTC)

Should comments be moved to discussion and a consensus formed around factual information regarding suppliers?

Local electronics and surplus stores[edit]


Sometimes it's difficult to tell from a picture on the web if something is really the right size. Local electronics stores let you see that it's exactly the right size, and often have a bargains bin. See the MightyOhm Wiki Surplus for a list of local Surplus Electronics Stores, plus some Swapmeets and Fleamarkets.
