content: I'm working on a little PCB to plug in place of a 40 pin DIP IC. I'mstruggling to think of what the header that's used to adapt the PCBto the socket is called. So I'm having a hard time finding this thing.I did a visual search of the Mill-Max catalog and came up with the151-10-640-00-010000. Spec's here:http://www.mill-max.com/images/products/pdf/053N.PDFThis looks like it will work since it has pins small enough to fit ina DIP IC socket. So solder one side to the underside of the PCBand plug the other side into the DIP socket. Done!Well, not done. No one seems to have any variant of these Mill-Maxparts in stock and the min qty is 50 at Digikey if they did have themand they cost $17-$20, ouch!Anyone know of a similar thing made by someone else? Or what thiskind of header thingy is really called so I can go searching for it?Scott

content: You can use standard 0.1" pin headers, they come in long rows that you can cut to size.I mean these ones:http://shop.rabtron.co.za/catalog/images/pin%20header%2040%20pin%20single.JPG]http://shop.rabtron.co.za/catalog/images/pin%20header%2040%20pin%20single.JPG

content: Something like that seems hard to find for sure!Can you use 2 headers rows with the same pitch instead?http://cgi.ebay.com/5X-40Pin-2-54mm-Pitch-Single-Row-Header-DIP-Strip-PCB-/280526377228

content: Sounds like this:Can you find some smaller gauge headers? I know the standard headers will just about ruin a standard dip socket.

content: Yeah, the problem with standard headers is that the pins are too bigto fit in an IC socket, at least without forcing them in.Thereareheaders made just for this use, like the Mill-Max, notice thatthe pins are intentionally smaller than the standard 0.1" header stuff.Just need to find something I can actually buy.Scott

content: Maybe round pin headers would do the trick then?http://cgi.ebay.co.uk/10xGold-Plated-2-54mm-Male-40Pin-Round-Pin-Header-Strip-/180600855648?pt=LH_DefaultDomain_0&hash=item2a0ca65c60#ht_1590wt_907
