Product Introduction — 24-Position Unshrouded Header
The FCI 68022-124HLF is a 24-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100-inch (2.54 mm) pitch on both rows and contacts, with all 24 positions loaded. The male square pins are through-hole mounted in a right-angle orientation, making it suited for board-edge connections where the mating axis runs parallel to the PCB. Rated at 5 A per contact and 110 V, with a 30.0 µin gold mating finish on phosphor bronze contacts, this header is built for repeated mating cycles in signal-level board stacking. The black UL94 V-0 rated housing provides the required flame retardance for equipment inside an enclosure.
Lifecycle & Sourcing — Obsolete, Sourced to Order
No official successor order code is on record from the manufacturer. A replacement search should focus on the BERGSTIK® II series at the same pitch and position count.
Key Ratings & Fit — What They Mean for Your Board
The 0.100-inch pitch is the standard 2.54 mm grid, which means the footprint is a drop-in match for legacy through-hole layouts and common perf-board patterns. The 24 positions in two rows give a 12-per-row pinout — verify your circuit count matches before committing the BOM line. The 30.0 µinch gold plating on the mating surface is a solid grade for repeated mating cycles and corrosive environments — it is not a thin flash. The 5 A per contact rating is typical for a signal header at this pitch; the limiting factor is the temperature rise in the housing, not the contact itself. Right-angle mounting places the pins parallel to the board, which is the right choice when the mating receptacle approaches from the board edge. The unshrouded design means there is no plastic wall around the pins — the mating housing provides the alignment and keying.
