The FCI 87900-154HLF is a 54-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications where a reliable, solder-through-hole connection is required. The 0.100" (2.54 mm) pitch matches the industry-standard grid, making it a direct fit for common prototyping and production footprints. Each male pin is rated at 5 A, with a 30.0 µin gold mating finish that supports repeated mating cycles in controlled environments. The black UL94 V-0 rated housing provides flame resistance for equipment installed inside enclosures.
Within the BERGSTIK® II family, the 54-position 87900-154HLF sits at the high end of the position count range. The 0.100" row spacing mirrors the pitch, giving a dense but routable 2.54 mm x 2.54 mm grid. The unshrouded design means the pins are exposed — a consideration for board layout where a shroud would otherwise block access or add height. The 0.120" (3.05 mm) solder post length suits standard 1.6 mm PCBs without excessive tail protrusion.
