Screw Terminals 3.5mm Pitch (2-Pin)

Screw Terminals with 3.5mm pitch pins. Comes in 2, 3, or 4 positions and have the really cool feature of slide-locking together to form any size you need (4, 5, up to 20 without problems). Rated up to 125V @ 10A. Terminal can accept 16 to 26AWG wire. 3.5mm/138mil pin pitch will not fit standard 0.1" perf boards but this is the most common pitch screw terminal.

Connector Basics

January 18, 2013

Connectors are a major source of confusion for people just beginning electronics. The number of different options, terms, and names of connectors can make selecting one, or finding the one you need, daunting. This article will help you get a jump on the world of connectors.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

    Which orientation on the Eagle part is supposed to have the wires?

    Here, I am assuming the side with the silkscreened circle is the side where the wires come in. Is this correct?

  • Victor Z. / about 13 years ago / 8

    Guys, that would be nice if you post EAGLE Library part names with each product posting. :)

  • silverfox / about 12 years ago / 4

    I found one at Digikey (part number A98334-ND) with a 2.54mm (0.1") pitch.

    • UNTEngineer / about 12 years ago / 1

      But this one has a 3.5mm pitch, which probably means beefier pins, and a higher current rating.

  • UNTEngineer / about 12 years ago * / 2

    FYI, I found something similar on Mouser: 571-284391-2.

  • DuinoLabs / about 12 years ago / 2

    Please, make this product cheaper. At least, make a minimum package (like 10 units) for a lower price.

    Thank you,

    There's also the CON-WAGO-500 library has W237-102, and others that should work for this.

    • Member #146848 / about 12 years ago / 1

      From looking at the data sheet this in incorrect. The W237-102 has a 5mm pitch.

  • RocketDesigns / about 10 years ago / 1

    The write-up on the page here says 6 amp, but the datasheet says 10. Which is it, please?

  • Julian4 / about 10 years ago / 1

    How far do you have to space them in Eagle so that they can "lock" and sit flush next to each other on the PCB?

    • Check the Eagle library footprints. You can space them out according to that, and line them up next to each other.

      • Julian4 / about 10 years ago / 1

        Tony, then datasheet only shows the footprint for the 3-pin version and I have the 2-pin. By any chance do you know if the space from the pin to the plastic edge is the same on both versions? That's the only measurement I need.

        • As I said, check the Eagle footprints in our Eagle library. The 2 and 3 pin versions are both in there and have been tested, so you can use the 2-pin version to lay out your board.

  • Eide / about 11 years ago / 1

    IMAGE VERY MISLEADING. (Yes, I am yelling.) Please change the product image! I thought I was getting the lot - nope. One. Little. Terminal. Don't get me wrong, it's what I needed, but now I wait another week, plus $10 shipping, to get what I wanted in the first place - four 2-pin terminals. AAAAaaaarrrrrgggggghhhh! #bunchacrap

    • Sorry about the confusion. I'll see what catalog can do to make the descriptions/images clearer.

  • BobCochran / about 12 years ago / 1

    I ordered 2 of these for my Big Easy Driver and they fit that board quite nicely. I should have taken a chance and ordered 10 of them in my original order. Then I'd have more than enough for all the connections on the Big Easy.

  • Member #183149 / about 12 years ago / 1

    I found this part in the library but I can't figure out which side is the front and which is the back. Can anyone hook me up with this info?

    • Member #183149 / about 12 years ago / 1

      I figured it out. The side with the two lines should be facing the edge of the board.

      • anyhow, it's a straight line of pins, Wouldn't matter too much if you just flipped the part itself during assembly ;)

  • Decbrad / about 12 years ago / 1

    Hey! Is this product okay for use with the QuadStepper board? It says in the description above that it comes in 2 or 3 positions! Which is it? The Quad requires 2


  • SHOOTER1 / about 12 years ago / 1

    I need the PRT-08084 Terminals.

  • PSmith / about 15 years ago / 1

    You're lucky. I just spent two hours trying to add the "SCREWTERMINAL" package to a design before finally seeing these comments here. I'd have never thought to look under "MO2" up above in devices if I hadn't seen what you guys wrote here.

  • silverfox / about 15 years ago / 1

    If this part is really on the Eagle library, I can't find it by searching for screw, terminal, or prt-08084. I believe I have the latest library as of 5/7/09. How do I find it in the library?

    • daveho / about 15 years ago / 3

      I think I found it - if you select "M02" ("Header 2") in the SparkFun library, there are a bunch of parts, one of which is "MO23.5MM".

      • CD / about 15 years ago / 2

        Wow, that was annoying! I just spent an hour looking for that part. I think you're right, it's under M023. Sparkfun should fix that!
