72-Position SIMM Socket for Legacy Memory Modules
The 5822021-4 is a 72-position SIMM socket from TE Connectivity's Micro-Edge series, designed for single in-line memory modules. It mates with standard 72-pin SIMM RAM modules per the MO-116 form factor — the pinout follows the JEDEC standard for 72-pin SIMMs, with address and data lines assigned per the module's edge connector layout. Tin contact finish at 200.0µin thickness provides adequate wear for a limited number of insertion cycles — typical for a socket that sees module installation once during system assembly and occasional field upgrades. The board guide aligns the module during insertion, and the latches lock it in place against vibration and memory-bus retention forces.
Through-Hole Mounting and Board Integration
Through-hole mounting gives the socket stronger mechanical hold than an SMT variant — important when the SIMM insertion force is transferred to the solder joints. The standard-top mounting feature means the module sits parallel to the PCB, typical for desktop or workstation memory layouts where z-height is not the tightest constraint. The connector ships in a box — each unit is individually packaged, not on tape-and-reel, so it is suited for hand-assembly or low-volume production runs.
The part is ROHS3 compliant.
