Pins for DIP 8 adapter

[jimk04]

I bought some little SOIC to DIP pcbs to swap in a THS4032 into a DAC that has the usual DIP 8 socket.

The pcb has 8 holes as you would expect. I have some 2.54p headers that I thought fitted the bill but the pin is too thick for the socket for the op amp.

I cant seem to find on RS what I need. Any guidance?

Thanks

There are complet DIP08 headers, which I can't find right now, but I have also used this:

Thanks Jan. I have seen those you linked to but wasnt sure if the pins were small enough diameter. I'll give something like that a try.

I found these but cant find them in single numbers

I also have similar, but gold plated pins.
If you buy them gold plated I'll take a bunch off of you ;-)

I'll see what I can find now I have a bit more info....thanks!

I bought these:

Seems to work OK. At USD 0.01 per pin it is not a bad deal. Delivery is relatively slow though.

Great....I think we are getting there.

Found these in the UK and still works out cheap

Perfect catch. I used similar from another vendor for the same price for a piggyback pcb for adding decoupling capacitors for my TDA1541 in my Philips based CD Players

For me they are too long.
So I just use 0.6mm silver plated copper wire.
Solder them to the adaptor PCB first using a DIP IC socket as pin positioning fixture.


Cheers,

I think the question was for:

IC_DIP sockets - POS - b-t-b

And the earlier posted link to RS, if you replace the trailing -99 by -55 you get the gold plated version.

Turned pin headers (round, about 0.5mm) are for DIP sockets (especially those with round holes).


Square pin headers (0.65mm across, 0.85mm diagonal) - Dupont style, will not normally fit IC sockets, they are the same size as IDE connector pins and frequently used for inter-board connectors.

Typical IC pins are 0.45mm x 0.25mm (about 0.5mm diagonal)

Why not cut the legs off two 1/4 watt resistors and use those to fabricate your "pins" ?

Bend one of these pieces of wire into a U-shape, where the lead-to-lead spacing is 2.54mm (0.1"). Then insert it (on the component side of the adapter PCB) into a pair of adjacent holes. Tape it down, turn the PCB over, and solder the two legs. Remove the tape and cut away the middle part of the U, removing the pin-to-pin short circuit.

Repeat a total of four times, giving you eight legs. Trim legs to 10mm length, done.

They're not especially stiff but they don't need to be. Because they are short, there's far less chance of bending them accidentally when you insert into a socket.

I did this myself when making a DIP adapter for the OPA1622 (10 pin VSON SMD package with thermal pad). Sorry for the crummy photo quality

I ordered the super cheap ones on eBay, linked by JensH above. They arrived in the US after 10 days and are acceptably high quality. Thank you, Jens!

Thanks for reminding. I just ordered a set as well.

This morning the seller shows Zero available. I am partially responsible; I bought ten sales-units at 400 pins per sales-unit.

[jan.didden]

Yes, when I ordered, he had 1 left, which I took. I am older than you so need less lifetime stock ;-)

so it was you! xD
there’s also a 5x version from same seller, i guess a bit more expensive / pin
