Facing issues sourcing the MJ-4PP-9 #16

Closed strayer closed 5 years ago

strayer commented 5 years ago

Hey, this is a little off topic, sorry for that. I'm having issues sourcing the MJ-4PP-9 TRRS jack in Europe (or anywhere outsite of Japan, to be precise).

I ordered some 4 pol TRRS jacks, but the connections on those will require some hacking on the PCB – so any tips where I could find the MJ-4PP-9 internationally would be greatly appreciated!

The ones I ordered are these: FC68125 https://cdn-reichelt.de/documents/datenblatt/C160/4%20POLE%20JACKS.pdf

I did find these on AliExpress, which are very similar: https://datasheet.lcsc.com/szlcsc/Made-in-China-PJ-320A_C12569.pdf

There are some differences in the spacing of the pins (around 0.2mm), but that could fit.

Hey @GreenShadowMaker, thanks for confirming! Those are the ones I purchased on AliExpress, so I guess I'm fine. I'm still debating wether I should modify the footprint, but the sizes are off by such a tiny amount (0.1mm - 0.2mm) that I might just risk it.
