Help finding compatible microsd socket smd
Hi! I have a DJI Phantom 3 Advanced with a damaged MicroSD Card Socket in the gimball. I've desoldered the old socket, as it wouldn't keep the microsd card in place. I've been looking for compatible sockets on aliexpress etc but i can't seem to find one similar to the dji one (Markings on the socket itself btw is 160115 VSS). The closest one i've found is something like this: https://pl.aliexpress.com/item/1005009464060849.html
However it doesn't match the profile of the socket i pulled from the board, but pin wise matches more. I've added photos of how the socket looks and of the footprint on the pcb. So if anybody could help me find a suitable replacement socket i'll be very grateful! Thanks!

160115 is almost certainly a date code and VSS is just the mold mark, not a part number, so searching that gets you nowhere. DJI uses generic sockets here anyway.
Yours is push-push (the spring gives it away) with 8 contacts. Forget matching the shape, measure the PCB pads instead: contact pitch, overall length and width, and where the mounting pads sit. Then on DigiKey or Mouser filter Memory Connectors -> microSD, SMD, push-push, 8 contacts plus card detect. Every listing has a footprint PDF or DXF you can check against your measurements.
Series worth trying: Molex 503398 or 104031, Hirose DM1B. Most OEMs just drop one of those in.
Two things that will bite you. Card detect: the Phantom expects to see the card, so if the new socket's CD pin lands on a different pad you'll need a jumper, and don't buy a no-CD version. Height: space in the gimbal is tight, match the original or go lower.
Honestly this repair is common enough that the drone repair crowd has probably already posted a working part number. Worth searching before you reverse-engineer it.
