The mating pin length of 0.400\" (10.16mm) provides ample engagement depth for the receptacle. The insulation height of 0.425\" (10.80mm) and the 0.156\" pitch together set the z-height budget above the PCB — verify clearance to adjacent components or enclosure lids. ## Comparison with Peer Headers Compared to the 1-292164-1 (11 positions, 2.00mm pitch, right-angle, detent lock, 125VAC), the 1-640445-9 offers more circuits (19 vs 11), a wider pitch (3.96mm vs 2.00mm), higher voltage rating (600VAC vs 125VAC), and a vertical orientation with friction lock — a fundamentally different fit for power-distribution or high-voltage boards rather than dense signal routing. The 1379030-3 (12 positions, 2.54mm pitch, right-angle, dual-row, UL94 HB) targets a different application space — board-to-board with board lock and mounting flange — whereas the 1-640445-9 is a single-row wire-to-board header with a higher flame rating (UL94 V-0 vs HB). The 1-1871673-2 (4 positions, 2.50mm pitch, right-angle, dual-row, detent lock) is a smaller, denser part for signal-level interconnects; the 1-640445-9's 19 positions and 3.96mm pitch suit higher-current or higher-voltage circuits where spacing is less constrained.","metaTitle":"1-640445-9 TE Connectivity MTA-156 Header 19 Pos 3.96mm","metaDescription":"Active TE Connectivity MTA-156 header, 19 positions, 0.156\" (3.96mm) pitch, vertical through-hole, friction lock, UL94 V-0.
