SODIMM socket for DDR2 AdvancedMC modules
The 1981284-4: This is a 200-position SODIMM socket from TE's AdvancedMC series, designed for DDR2 SDRAM modules. The 0.205" (5.20mm) height from the PCB to the top of the socket sets the clearance for the memory module. Pair it with a module that matches the 0.039" (1.00mm) card thickness.
Mechanical retention and alignment
Integrated board guide and latches handle module alignment and lock it in place — the latches resist dislodging under vibration, a common requirement for mobile or industrial systems. Gold-plated contacts give reliable mating over repeated insertion cycles, typical for field-serviceable memory slots.
