What This Micro-Edge SIMM Connector Does
The 5822138-3 is a 72-position SIMM socket from the TE Micro-Edge series, designed to accept RAM modules with a card thickness between 0.047" and 0.054". It mates at a 22° angle, which reduces the z-height above the board compared to a vertical socket — useful in tight card-cage or enclosure layouts where the memory module sits at an incline. The gold contact finish is 30.0µin thick on the mating interface — enough for repeated module insertions over the product service life without exposing the base copper. In a field-service environment where a technician swaps RAM quarterly, that gold layer supports several hundred cycles before wear-through. Board guide and latches are integrated into the housing, so the module aligns on insertion and locks without a separate clip. The connector follows the MO-116 outline standard, which means the footprint and slot position match industry-standard SIMM layouts from the 72-pin era.
Because the part is no longer in active manufacture, there is no factory lead time to quote. Sourcing is per-RFQ against available surplus inventory. The base product number 5822138 may help identify family-compatible siblings, but no pin-compatible drop-in replacement from TE has been published.
Fit Check — What It Mates With
This is a through-hole, top-mount SIMM socket. It accepts standard 72-pin SIMM modules with a PCB edge thickness of 0.047" to 0.054". The 22° insertion angle means the module sits at an angle when mated — confirm your enclosure clearance for the tilted profile, not a vertical module. The connector ships in a tube for hand-loading or automated insertion. No matching housing or terminal is needed — this is a one-piece socket that receives the memory module directly.
