The square pins are made of phosphor bronze with a mating-side contact finish of gold or GXT™, plated to 30.0 µin (0.76 µm). Rated at 5 A per circuit and 110 V, the black PA housing carries a UL94 V-0 flammability rating, making it suitable for equipment inside an enclosure. The 0.100\" (2.54 mm) pitch is the standard for legacy through-hole layouts and matches a wide range of mating receptacles and prototyping boards. The 31-position count is the critical BOM line match — verify your circuit count against this number.","metaTitle":"Amphenol FCI 87185-131HLF BERGSTIK II Header, 31 Pos","metaDescription":"Amphenol FCI BERGSTIK II 87185-131HLF unshrouded header, 31 positions, 0.100\" pitch, 5 A, 110 V, gold plating, UL94 V-0.
