It carries 38 positions loaded across two rows on a standard 0.100\" (2.54mm) pitch, with the same 0.100\" row spacing. The square pins are phosphor bronze with a 30.0µin (0.76µm) gold or GXT™ finish on the mating surface, rated for 5 A per contact at 110 V. The through-hole solder tails extend 0.120\" (3.05mm) below the insulator, and the overall contact length is 1.040\" (26.42mm). The black UL94 V-0 rated housing is unshrouded with a push-pull fastening type, making it a straightforward board-level interconnect for parallel PCB stacking or wire-to-board via a mating receptacle. ## What the key ratings mean for your fit The 0.100\" pitch and row spacing are the industry-standard 2.54 mm grid — the footprint is a known quantity for any board layout engineer. The 30.0 µ\" gold plating on the mating surface is the important detail here: that thickness supports hundreds of mating cycles without contact resistance drift, which matters if this header is on a card that gets swapped during test or field service. The 5 A per-contact rating is typical for this pin size and pitch; the practical limit in a dense dual-row header will be set by the total current and the ambient temperature, not the contact itself. The unshrouded design means there is no keying or polarization — the mating receptacle must be aligned by the board layout, and the pins are exposed for probing but also vulnerable to bending if the mating connector is misaligned.","metaTitle":"Amphenol 87901-138HLF BergStik II Header, 38 Pos","metaDescription":"Amphenol 87901-138HLF BergStik II unshrouded header, 38 positions, dual-row, 0.100\" pitch, 5 A, 30 µ\" gold plating.
