BERGSTIK® II 86503-158HLF — 58-Position Unshrouded Header
The Amphenol FCI 86503-158HLF is a 58-position, dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch. It carries 5 A per circuit at 110 V, with gold or Gold GXT™ plating at 30.0 µ" (0.76 µm) on the mating surface — enough margin for repeated mating cycles in a corrosive environment without a cost premium over heavier gold. The through-hole solder tails are 0.120" (3.05 mm) long, and the overall contact length of 0.470" (11.94 mm) gives a 0.250" (6.35 mm) mating interface for secure board-to-board stacking.
Mating and Footprint
The 0.100" row spacing mirrors the pitch, keeping the footprint a simple 2 x 29 grid of 0.028" square pins. For a 58-circuit BOM line, confirm the receptacle has all 58 positions loaded and the same row spacing.
