content: Hi,I want to replace socketed DIP ICs with a PCB. I have a TRS-80 with a row of eight 4116 DRAM chips (16K x 1) that I want to replace with a PCB with a static RAM chip on it (and an 8 bit register to de-mux the address).My concern is, what headers can I use that will solder into my PCB on one end and plug into the DIP sockets on the other end without damaging them? DIP IC pins are a lot thinner than typical 0.1" pitch rectangular header pins, and I'm worried the header pins either won't fit in the DIP socket or they'll permanently damage it.Any suggestions?Thank you,Bob

The tapered side is thin enough to not damage IC sockets or breadboards.If you really want to ensure an optimal connection, replace the TRS-80's regular DIP socket with a machined one, too.

content: If this is a one-off that you don't mind to bodge with duct tape and bailing wire, and you can't find anything cheap enough:Maybe you can find a DIP network resistor of the appropriate footprint in something like 10 megaohm to attach fly wires to.If you have the tools, you can also just center drill/mill any IC of the right footprint which has a small wafer to leave the pins to solder to.It's hard enough to get one 8 pin DPI IC into a socket without bending a fimsy pin. It might prove difficult to seat 8 of them as one piece, anyway.

content: Could you get another DIP socket, put the headers into that (potentially mangling that) and then stick that socket into the 'good' socket?At least that way you've kept some of the damage at one layer of indirection from the board. It would probably work OK unless you were repeatedly removing and reinstalling it.

content: I'm looking for something similar so I can plug in microcontrollers into IC sockets.The sockets needed for header pins commonly used for microcontrollers and similar development boards are unnecessarily tall for permanent/semi-permanent projects.Want something lower profile.I realize the width of such boards aren't standard for say 40 pin ICs and related sockets, but if you get the socket strips designed for ICs, that would work for the socket/female side of the equation. But one would need the corresponding male pins/headers for the component.It would still work for breadboards, since you can plug regular ICs into breadboards.

content: I use this sort of thing and they work great.https://www.ebay.com/sch/i.html?_nkw=round+pin+headerThese work great too, but may be hard to find outside Japan, but the link provided by Alex Eisenhut is equivalent.https://akizukidenshi.com/catalog/c/csocket6/

content: Quote from: TERRA Operative on January 17, 2024, 04:59:01 amThey work great once. After that the socket contacts are usually too loose to accept anything else. :/There are machined pin headers with thinner 0.4mm pins, but you have to look for them.
