Hi Guys,

I have been searching for a long time to find some header pins that will fit smaller diameter holes in my pcb.

The only ones I can find have a pin diameter of 0.64mm, which is too big for most of what I need.

I was wondering if anyone knows where to find smaller diameter pins?

I normally get these ones (see below).

But that's the standard size, why do you want them smaller?

If you can use the 1.27mm pitch, they are thinner.

Those pins fit standard 0.1 inch spacing headers. Do you want to use standard headers?

If so, you would need pins that are this size above the board and smaller below the board.

Or can you use 2mm spacing headers?

The spacing is right, just the size of the pin is too big. I built a few adapters with these pins. They don't fit into a machined dip socket. When they are inserted in a cheap dip socket, they stretch the pins wide open, then the microcontroller is loose.

I have seen some smaller pins on a few aries adapters I have, but I can't seem to find the header pins anywhere.

I do not understand what you are doing.

I often use a file to file down pins for specific purposes.

EDIT: Well I guess you have a dip socket on a board that you sometimes plug a chip into. At other times you want to plug in a cable. I don't have the solution, but maybe someone else does.

Yeh but how did you get the thread title to appear as a different blue?

If you are talking to me, I think that happens whenever I upload a virus.

I have some things here that plug into DIP sockets and wires could be soldered to them. But I have no idea what they are called, and they probably haven't been made in many years.

EDIT: On the bottom they have CA-16P and CA-24P respectively.

No, I'm asking the OP, in my listing, this is the only title that is dark blue, all the rest are light blue or lighter blue dependin on if I've looked at them. This one stands out and I'm wondering how?

Okay, now the color is back to normal. Hmmm...

I quit worrying about colors years ago.

Click on the first line of the data sheets, first item 350-10-164-00-001000. The 164 means 64 pin strip, I think you can get shorter types. Farnell also carries similar.

eidt actually the second line of the data sheets shows the metric types.

Eeeek! $10 for 64 pins!! That's about the same as one of my local shops, and they are usually akin to highway robbers.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

But they are gold plated. GOLD!! So you must pay for that. :wink:

May be able to get some tin plated elsewhere at a cheaper price.

That's perfect John! Except for the price.
The 0.46 diameter thickness is what I would need.

The ones I have been using are 0.64 mm thickness, which stretches out the holes. (kinda reminds me of something similar):)
