How much thicker is a square header pin than 22AWG solid wire?
« on: January 08, 2014, 01:07:02 am »
From what I can find square .1inch header pins like the ones use in IDE connectors are usually .635mm thick.
22AWG seems to often be referred to as .6mm. Does this sound right?

Each face of a square header pin is .035mm thicker than diameter of the round cross section of 22AWG solid wire?
Diagonally a square pin is even thicker at .898mm if my a2 + b2 = c2 calculation is correct :)


Oops. I just checked Wikipedia and found the table where 22AWG seems to be 0.644mm so I guess it's so close to the size of a square pin (when it's not turned 45 degrees) it might as well be the same.
I might see if I can find a way to flatten the corners of square pins to make it more octagonal.

What you want to be comparing is the CSA (conductor surface area).

22AWG has a CSA of around .35mm².

A .635mm square pin has a CSA of around .4mm²

Although after rereading your OP I'm not sure what your question is?

I'm just wondering about the thickness because I know that using anything thicker than 22AWG wire in a breadboard eventually loosens up the clips.
It has nothing to do with conductivity or anything serious :)
