It uses the standard 0.100" (2.54mm) pitch on both the pin-to-pin and row spacing, which maps directly to legacy DIP footprints and common perf-board layouts. This is a board-to-board interconnect — unshrouded, so the mating receptacle needs its own keying or the assembly relies on external alignment.
Rated 5 A per contact at 110 V — the current is typical for a 0.100" pitch pin header, but the tin plating on both the mating and post surfaces is the real duty-cycle governor. At 100.0 µin (2.54 µm) on the mating side, it's a heavy tin wipe good for a moderate number of insertion cycles, but it's not a gold-plated contact for high-reliability or corrosive environments. All 12 positions are loaded, so there's no option to depopulate for a custom pinout — what you see on the BOM is the full circuit count.
No official replacement or cross-reference exists for the 12-position, right-angle, tin-plated fit.
