The 2.20mm pitch and dual-row layout with 3.00mm row spacing give it a compact footprint for routing 12 circuits in a space-constrained junction box or inline splice.
The 1746872-1 housing accepts 0.64 series female socket crimp terminals — the same contact family as the housing series.
No official second source or cross-reference is listed; the 0.64 series is a TE Connectivity proprietary platform, so the mating half and terminals should also be sourced from TE.
Pitch and Row Spacing for Footprint Planning
The 0.087" (2.20mm) pitch and 0.118" (3.00mm) row spacing define the cavity layout for the 12-position, 2-row housing. The 2.20mm pitch is tighter than the common 2.54mm (0.100") standard, which means the mating header or receptacle must match this exact pitch — a 2.54mm header will not align. The 3.00mm row spacing is wider than the pitch, giving the dual-row connector a rectangular cavity pattern that fits standard 0.64 series headers and receptacles.
