The 5-104192-4 is a double-row vertical board-mount receptacle connector designed for the AMPMODU Interconnection System with 15 positions and 0.050 x 0.100 inch (1.27 x 2.54 mm) centerline spacing. The housing is constructed from glass-filled thermoplastic rated 94V-0, providing durability and flame resistance. Contacts are made from copper alloy with duplex plating: 0.000030 inch (0.00076 mm) gold in the mating area, 0.000150 inch (0.00381 mm) tin on solder posts, and 0.000050 inch (0.00127 mm) nickel underplating for enhanced corrosion resistance and reliable electrical performance. This receptacle is ideal for board-to-board interconnections in applications requiring compact, high-density connector solutions with consistent electrical and mechanical reliability.
