The Amphenol FCI 87052-402HLF is a 2-position, dual-row male pin header from the BERGSTIK II series. It is an unshrouded, board-to-board style header with a 0.100" (2.54 mm) pitch, designed for through-hole solder termination. The tin-plated phosphor bronze contacts are rated 5 A per circuit at 110 V, with a thick 100.0 µin (2.54 µm) tin finish on the mating surface. The black UL94 V-0 rated housing and push-pull fastening make it a straightforward, general-purpose interconnect for PCB stacking or wire-to-board applications where a low-profile, unshrouded header is acceptable.
What the ratings mean for fit
The 5 A per circuit rating at 110 V is typical for a signal-level header on a 0.100" pitch. The 100.0 µin tin plating on the mating surface handles repeated mating cycles better than a flash finish, but it is still a tin-to-tin interface, so it is best suited for applications with moderate cycling and benign environments.
