The Amphenol FCI 68705-426HLF is a 26-circuit single-row unshrouded male header from the BERGSTIK II series, built for board-to-board interconnect on a standard 0.100" (2.54 mm) pitch grid. The tin-plated phosphor bronze contacts carry a 5 A per-circuit rating at 110 V, and the black UL94 V-0 polyamide body keeps it compliant for equipment inside an enclosure.
The 0.100" (2.54 mm) pitch is the de facto standard for through-hole prototyping and legacy board layouts — it matches the common perf-board grid and allows two traces between pads on a typical 0.062" board. The 5 A per-contact rating is the thermal limit at the contact itself, but in a 26-position single-row header the practical current is limited by the total bundle temperature rise; expect to derate if every circuit runs near 5 A simultaneously. The tin mating finish (100.0 µin / 2.54 µm) is thick enough for moderate mating cycles in a one-time-assembly or periodic-service scenario — not for frequent field reconnection.
The through-hole solder termination has a post length of 0.095" (2.41 mm) and an overall contact length of 0.395" (10.03 mm), with the mating pin extending 0.200" (5.08 mm) above the insulation. The 0.100" (2.54 mm) insulation height keeps the mated stack low-profile.
No official cross-reference or direct substitute is on record — the BERGSTIK II series includes many 0.100" pitch single-row headers at different position counts and plating options, but none is a drop-in replacement for this exact 26-position tin-plated variant without verifying the BOM line.
