86832-172HLF — what it is
The Amphenol FCI (Amphenol ICC) 86832-172HLF is the 72-position member of the BERGSTIK II series — a dual-row 0.100" (2.54 mm) pitch unshrouded board-to-board header intended for through-hole soldering in mid-density signal and power interconnection. The 0.100" row spacing and dual-beam square-pin geometry are consistent with standard 0.100" pitch pin-header footprints used across industrial control, instrumentation, and consumer electronics boards. All 72 contacts are populated in the as-supplied configuration. The contact finish is gold or Gold GXT at 30.0 µin (0.76 µm) thickness on the mating interface, over a phosphor bronze base. Rated 5 A per circuit at the contact level, with a 110 V voltage rating and UL94 V-0 flammability classification.
What the key ratings mean for your BOM
72 positions in a dual-row layout at 0.100" pitch is the primary BOM-match check — the board footprint and routing density must accommodate the full configuration with standard 0.100" grid spacing.
