You can pick up these neat TSOP48 ZIF sockets on eBay. I’ve been using them for a TSOP48 NAND flash reader which will eventually be available on my shop.
The footprint is kind of fiddly. And I’ve attached the second rev for Kicad below. I’ve not yet tested this version but r1 worked well enough that this is likely ok. In r1 the pins needed moving out ~0.5mm (socket fit, but it was a squeeze) and I need to remove the mechanical mounts as they were off by about 1mm.
