The 36 positions are the primary BOM match: confirm your circuit count against this number, not a nearby variant. The 5 A per contact rating is adequate for signal-level currents and moderate power distribution, but the tin plating (100.0 µin / 2.54 µm on the mating surface) limits the connector to applications with fewer than 50 mating cycles — tin wears faster than gold under repeated engagement. For a one-time assembly or infrequent field service, tin is cost-effective; for frequent reconnection, a gold-plated sibling would hold up longer. The overall contact length of 0.538\" (13.67 mm) with a 0.318\" (8.08 mm) mating section means the pin protrudes enough for a positive wipe inside the receptacle socket.","metaTitle":"78511-436H Bergstik II Header, 36 Pos, 0.100\" Pitch, 5A","metaDescription":"78511-436H Bergstik II unshrouded header, 36 positions, 0.100\" pitch, tin-plated, 5A, UL94 V-0.
