BERGSTIK II 33-Position Unshrouded Header
The Amphenol FCI 68031-133HLF is a 33-position single-row unshrouded male pin header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch. It's a through-hole solder termination part, push-pull mating style, with all 33 positions loaded. The black UL94 V-0 rated insulation housing carries square phosphor bronze pins with 30.0 µin (0.76 µm) gold or GXT™ plating on the mating surface. Rated at 5 A per circuit and 110 V, this is a general-purpose board-to-board interconnect — the 33-position count is less common than 32 or 34, so confirm the BOM line matches exactly.
The 0.100" (2.54 mm) pitch is breadboard-compatible and matches legacy perfboard layouts — the footprint is a row of 33 through-holes on 2.54 mm centers. The overall contact length of 0.513" (13.03 mm) with a 0.230" (5.84 mm) mating length and 0.183" (4.65 mm) solder tail gives a standard through-hole standoff height.
