The 5176264-4 is a double-row, vertical surface-mount header connector from the AMPMODU Interconnection System, designed for board-to-board connections with 0.050 x 0.100 inch (1.27 x 2.54 mm) centerline spacing. The connector features a glass-filled thermoplastic housing rated 94V-0 in black, with copper alloy contacts duplex plated with 0.000030 inch (0.00076 mm) gold in the mating area and 0.000150 inch (0.00381 mm) tin on solder posts, with entire contacts underplated 0.000050 inch (0.00127 mm) nickel. This 10-position configuration (5.0 x 0.39 inches per dimension A) provides reliable signal and power distribution in compact PCB layouts. The connector is commonly used in telecommunications, computing, and industrial control applications where space-efficient, high-density interconnection is required.
