Board-to-Board Header Selection Note
The Amphenol FCI 86832-124HLF is a 24-position, dual-row male header from the BERGSTIK II series, built on the standard 0.100-inch (2.54 mm) pitch. The through-hole solder termination suits wave-solder assembly, and the 0.100-inch (2.54 mm) mating and post lengths give a typical mated stack height in the 0.500-inch range when paired with a standard receptacle — check the overall contact length of 0.525 inches (13.34 mm) against your board-to-board spacing budget. The 5 A per circuit rating at 110 V covers signal and moderate power duty; the 30.0 µin (0.76 µm) gold or GXT plating on the mating surface supports repeated mating cycles without contact fretting.
Plating and Duty Cycle
The UL94 V-0 rated black insulation (0.100-inch / 2.54 mm insulator height) meets the flammability requirement for equipment inside an enclosure.
