What this 12-position receptacle does in the assembly
The forked contact design gives a reliable wipe on the mating pin, and the tin-on-tin finish keeps the cost down for moderate-cycle applications. Rated at 100 VDC and spanning -40°C to 105°C, it's suited for signal-level interconnects in automotive and general-purpose gear — think ECU boards, sensor modules, or control panels where the environment isn't sealed but the temperature stays inside that window.
The 12 positions are all loaded, meaning every pin is present; no unpopulated spots to watch for on the BOM. Insulation height is 0.157" (4.00mm) above the board surface, and the contact post length is 0.122" (3.10mm) — enough for a standard 1.6mm PCB with a bit of tail for solder fillet visibility.
The closest functional second-source is 1-2823056-2, also a 12-position, 0.100" pitch Micro-MaTch receptacle, but in a black housing with surface-mount termination instead of through-hole. If your board is SMT-only and you need the same position count and pitch, that's the swap — but the through-hole kinked pin of 1-215079-2 gives better mechanical retention on a single-sided board.
