Description: This DC power jack/connector is just like the other one that we carry except that it’s terminated with breadboard-friendly pins instead of wide solder terminals. These are also compatible with our DC wall supplies and have a 5.5mm jack, with a 2.1mm center pole diameter.

  • Just FYI, while the Sparkfun Eagle library doesnt currently have this part, the Adafruit Eagle Library does.

    • I believe it’s “SparkFun-Connectors > POWER_JACK > POWER_JACKPTH”. Please correct me if I’m wrong.

      • NOT CORRECT - there is currently (11/28/2013) no part like this in the SF Eagle Library.

        • POWER_JACK_PTH will work as well, just that the pads are unnecessarily large, and the component outline isn’t quite right for this specific component. Nonetheless, I’ll submit a pull request for a lib that has this one added.

  • Eagle’s standard library just worked fine for me. con-jack -> DCJ0303

  • Does anyone know if these will work on a board printed by OSHPark using the correct layout, but with standard sized pin-holes instead of the slots? I have the other barrel connector with the wider leads, but just received my boards from OSHPark and I see that they just have standard holes drilled without enough room for the fat leads on the other connector.

    I’m hoping that the posts on this one might fit in to the standard holes on my PCBs, but I can’t seem to figure out the dimensions for the pins on this from the drawing. Thanks in advance!

  • this is definitely not breadboard compatible

    • It should be - in what way is it not? (pins too big, pin spacing issue? what breadboard are you using?)

      If you’re certain it’s not compatible, you may have received the wrong part (perhaps you got DC Barrel Power Jack/Connector instead, should be easy to tell!), and should get in touch with .

  • When is this in stock again? This is the ONLY item in my cart that is backordered, and I chose Ship Complete Order!

  • Which pins go to what???

    • In the dimensional drawing there is a little circuit diagram: pin 1 (back) is the center pin, pin 2 (front) is the barrel, and pin 3 (side) is the “shunt”, which is connected to pin 2 when the plug is not inserted, and is disconnected from pin 2 by inserting the plug.

  • Can one use the same PCB footprint as the non-breadboard compatible jack?

  • Radioshack has ALL panel mount stuff; Breadboard friendly FTW!

  • Could this be fit directly into the power rails? It looks like the pin spacing might be a little too wide…

    • It looks like it could fit from the dimensional drawing, but some pin bending will be required. Once I get a few, I will test them in a real breadboard and find out for sure.

      Update: I have them in. Power rails? Not exactly - you have to bend the pins slightly, and there could be issues if you want to use the third pin. It’s far cleaner to put it in an empty section and jump it to the rails.

      • So the pin in back is power and the side and center pins are both ground… right?

        I’m got it plugged into the breadboard as shown in the picture, and I’ve attempted to jump it out to the power rails… but it doesn’t seem to be working for me (i.e., it’s not powering my led strip)

  • Yay!! I’ve wanted these for a long time. Cutting/Drilling holes in perfboard is doable, but dragging out the dremmel for just one component is a pain.

  • The other classic technique is to drill a hole in the perfboard and use a panel-mount jack. Free-wire from the back terminals back to your power circuitry.

Note about negative poles

It is worth mentioning that there is one positive and two negative poles while there is no plug plugged in. However, when the plug is plugged in there is only one negative and one positive pole (the one on the side is not used). Otherwise it is a very good product.

Great for breadboard work

I used one of these many times to easily power a breadboard. The only thing lacking here is the confusing circuit diagram in the datasheet. Otherwise, the product is great and fits perfectly in normal spacing breadboards.

Great power jack adapter

I highly recommend these if you are building PCBs. Well made, the small mounting pins easily mount to the PCB as advertised. Very sturdy once soldered.
