The Amphenol FCI 87901-148HLF is the 48-circuit member of the BERGSTIK II board-to-board header series — a dual-row, 0.100-inch (2.54 mm) pitch unshrouded male pin header with through-hole solder tails and a push-pull fastening interface. Rated 5 A per contact at 110 V, it carries gold-plated phosphor bronze contacts at 30.0 µin (0.76 µm) mating-finish thickness across all 48 positions. The UL94 V-0 housing makes it suited for internal board-to-board stacking in industrial control modules, instrumentation, and other enclosed equipment where flame-retardance is a board-level requirement. With 0.820 inch (20.83 mm) of mating length and 0.100 inch (2.54 mm) row spacing, the 87901-148HLF is sized for permanent board-stack configurations rather than field-service disconnects — the push-pull header is not designed for repeated mating in-service.
Board layout fit
At 0.100 inch (2.54 mm) pitch with 48 positions across two rows, the footprint covers the board edge. The 0.120 inch (3.05 mm) through-hole tail length is compatible with standard FR4 multi-layer PCB profiles; confirm the finished hole size and plating meets the solder wetting spec for the 0.820 inch (20.83 mm) mating-pin length.
