Compared to the 1-1871673-2 (4-position, 2-row, 0.098\" pitch, right-angle, detent lock, tin mating, 250VAC), the 3-644759-3 offers a wider 3.96mm pitch for easier routing and higher voltage (600VAC), but only 3 positions in a single row. The friction lock is simpler than the detent lock, and the gold mating contacts provide better cycle life than tin. Against the 1-292164-1 (11-position, 2.00mm pitch, right-angle, detent lock, tin mating, 125VAC), the 3-644759-3 has a coarser pitch and fewer positions but carries higher voltage and gold contacts — a trade-off for lower-density, higher-reliability applications.","metaTitle":"3-644759-3 TE Connectivity MTA-156 Header, 3 Pos, 3.96mm","metaDescription":"3-644759-3 TE Connectivity AMP Connectors MTA-156 pin header, 3 circuits, 0.156\" pitch, gold mating contacts, friction lock.
