The Amphenol 95687-170HLF is a BERGSTIK II dual-row unshrouded male header with 70 positions arranged 2×35. It uses a 0.100" (2.54mm) pitch on both rows and between rows — a standard footprint that matches the legacy 0.100" grid for prototyping and production boards alike. Through-hole solder termination with a 0.360" post length gives enough standoff for backplane or daughtercard routing, while the 0.820" overall contact length provides a solid mechanical anchor in the plated through-hole. Gold or Gold GXT plating at 30.0µin (0.76µm) on the mating surface handles repeated mating cycles without the fretting corrosion you'd see on tin at this position count.
Rated 5A per contact at 110V — the 5A figure is per-pin at the connector level, not a harness derating. In a 70-position header drawing near-rated current on every pin, the total thermal load hits the housing limits before the contacts do, so the UL94 V-0 black housing handles the temperature rise.
