Product details

The 78511-436H is a 36-position, single-row Bergstik II unshrouded header from the standard 0.100" (2.54 mm) pitch family.

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.

Frequently asked questions

What is the current rating of 78511-436H?

The 78511-436H is rated 5 A per contact. With tin-plated contacts, derate for higher ambient temperatures per the manufacturer's derating curve — the 5 A rating applies at nominal conditions.

What is the mating connector for Bergstik II header 78511-436H?

This unshrouded header mates with any standard 0.100" pitch Bergstik II receptacle housing that accepts 36 positions in a single row. The female housing provides the alignment and retention — no shroud on the header side.
