What this 40-position SMT header fits
The 1747642-2 is a TE Connectivity AMP Connectors header for board-to-cable/wire applications, with 40 positions loaded across two rows at a 2.20mm mating pitch and 3.00mm row spacing. The shrouded 4-wall design and latch holder fastening make it a vibration-resistant mate for automotive harnesses.
Surface-mount termination and board retention
The insulation height of 0.787" (19.99mm) and mating contact length of 0.224" (5.70mm) define the mated stack height — confirm clearance above the board before layout.
RoHS compliant, UL94 V-0 rated housing in black PPS glass-filled material.
Peer comparison: 1565476-1 vs 1747642-2
The 1565476-1 is a through-hole version with 16 circuits instead of 40, natural housing color, and a mounting flange instead of board guide — same 2.20mm pitch and latch holder.
