Board-fit and memory type match
The 1473149-1: This is a 200-position SODIMM socket with a 25° angle insertion, designed for DDR SDRAM modules. The 0.205" (5.20mm) height and board guide features help align the module during insertion, reducing the risk of bent contacts.
Contacts are gold flash — the thinnest gold plating grade. It provides corrosion resistance for the few mating cycles a SODIMM sees in its service life, but it won't survive repeated reconnects like a thicker gold plating would.
