The 5-1971875-4: This is the receptacle half of TE's Power Triple Lock, High Temp series — a 12-position, 3-row housing on a 6.00 mm pitch that mates with the corresponding plug and crimp terminals to form a wire-to-board or wire-to-wire connection rated for higher ambient temperatures than the standard Power Triple Lock.
The 6.00 mm pitch and 12-position count are the primary footprint match criteria for the board-side header or plug that this receptacle mates with — confirm the mating part's pitch and row spacing before committing the BOM line. The 3-row layout with 0.319" (8.10 mm) row spacing means the housing is wider than a 2-row equivalent at the same pitch — check the panel cutout dimensions against the product drawing. Compared to the 6-position, 2-row sibling 1-2069882-6 (5.08 mm pitch, free-hanging), this housing offers double the circuit count in a panel-mount package — a direct swap is not possible due to different pitch and mounting style.
RoHS compliant; supplied in bulk packaging.
