The Amphenol FCI 68031-118HLF is an 18-position, single-row unshrouded header from the BERGSTIK II series. It uses the industry-standard 0.100" (2.54 mm) pitch, making it a direct footprint match for legacy and current board layouts that call for a breakaway-style pin header. The contacts are male square pins with a gold or GXT plating finish at 30.0 µin on the mating surface — thick enough for repeated mating cycles in a corrosive or field-service environment. Rated at 5 A per circuit and 110 V, this header handles signal-level and light power interconnects on a through-hole board.
Key Specs and What They Mean for Your Build
The 0.100" pitch is the classic DIP-spacing footprint — it routes easily on a two-layer board. The 18 positions are all loaded, so the BOM line count matches the circuit count exactly.
Mating and Termination
This unshrouded header mates with any standard 0.100" pitch single-row receptacle housing from the BERGSTIK or equivalent series — the push-pull fastening means no latch, so the retention comes from the contact interference fit. The through-hole solder termination is compatible with wave or hand-solder assembly. The black insulation height of 0.100" (2.54 mm) leaves clearance for the receptacle body above the board.
Lifecycle and Sourcing
The 68031-118HLF carries an Active lifecycle status from Amphenol FCI — no end-of-life notice, no last-time-buy window. There is no official cross-reference or direct replacement on record, so confirm the BOM position count and mating half before committing.
