The Amphenol FCI 93939-422HLF is a 22-circuit dual-row unshrouded male header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect, though the unshrouded pins also mate with standard IDC receptacles for wire-to-board harnesses. Tin-plated contacts rated 5 A per circuit at 110 V, with a 100.0 µ" (2.54 µm) tin mating finish — a heavy plating that handles moderate mating cycles without fretting in low-vibration environments.
Footprint and fit
22 positions loaded in two rows at 0.100" (2.54 mm) row spacing — 11 pins per row. The 0.100" pitch matches the legacy 2.54 mm grid, so the board footprint lines up with standard DIP or header patterns. The 0.120" (3.05 mm) solder post length is typical for a 1.6 mm PCB — the post protrudes through the board for a clean solder fillet.
Current and voltage headroom
The 110 V rating gives enough creepage for the 0.100" pitch without forcing a wider board footprint. For a typical 22-circuit header carrying 2–3 A per pin, the temperature rise stays well within the housing limits. The 100.0 µ" tin mating finish is thicker than the common 30–50 µ" tin flash, so it resists wear through repeated insertion cycles better than a thinner coating.
Active lifecycle status — the 93939-422HLF is still in regular production with no end-of-life notice on record.
