BergStik II Unshrouded Header — 8 Positions, 0.100" Pitch
The FCI Amphenol 68031-208HLF is an 8-position, single-row unshrouded header from the BergStik II series. It uses a 0.100" (2.54mm) pitch, the standard footprint for BergStik board-to-board interconnects, and carries square male pins with a 0.230" (5.84mm) mating length. Rated 5A per contact at 110V, this is a signal-level interconnect — the current rating is adequate for logic, I/O, and low-power distribution, not bus-level power. The mating finish is 15.0 µ" (0.38 µm) gold or GXT, which gives a solid cycle life for production assemblies without the cost of heavy gold.
What the Ratings Mean for Fit
The 0.100" pitch is the critical dimension — it matches the entire BergStik receptacle family, so the board footprint is standard. The 8 positions are fully loaded (all positions populated), so the circuit count matches the BOM line directly. The unshrouded design means there is no polarization keying; the header orientation must be verified against the mating receptacle during board layout and assembly. The through-hole solder termination with a 0.183" (4.65mm) post length fits standard 0.062" PCBs with room for wave solder. The UL94 V-0 housing is standard for equipment inside an enclosure requiring flame rating.
