What This Connector Is
The 87900-152HLF is a 52-position dual-row board-to-board header in the BERGSTIK II series from Amphenol FCI. It carries 0.100 inch (2.54 mm) pitch on both the row spacing and the mating interface, with all 52 positions loaded — square male pins, unshrouded, push-pull fastening. The through-hole body mounts on 0.100 inch grid, making it a direct footprint match for standard 0.100 inch pitch receptacles and IDC headers in the same series.
Ratings That Drive the Fit Decision
At 5 A per contact and 110 V, this header sits squarely in signal-duty territory — enough for power bypass or low-level rail distribution, but the 30 µin gold or GXT plating grade is what tells you this is optimized for mating cycle life rather than high-current bus work. The UL94 V-0 flammability rating covers the housing in harness or panel environments where flame retardance is a procurement gate. The 0.720 inch (18.29 mm) mating length and 0.120 inch (3.05 mm) tail length describe the insertion envelope — the header needs a receptacle or IDC housing with sufficient entry depth to meet the full wipe distance. The 0.100 inch (2.54 mm) insulation height sets the standoff from the board surface when used as a board-to-board stacking member.
