100-position board-to-board receptacle for dense parallel-board stacks
The 87606-450HLF: This position count is high for a standard-pitch receptacle — it fills a full 5 inches of board edge, so the layout engineer needs to verify the keep-out zone and mating header footprint early. The tin-plated mating finish (78.7µin) is a cost-optimised choice for moderate mating-cycle applications — not for high-cycle field-service connectors, but fine for internal board stacks that mate once during assembly.
Pitch, position count, and housing details for fit checks
All 100 positions are loaded (no selective loading), so the mating header must also be a full-populated 100-position, dual-row, 0.100" pitch pin header. The housing is glass-filled thermoplastic rated UL94 V-0, and the insulation color is gray — a visual identifier on the assembly line. This is a standard signal-grade contact set for currents typically under 3 A per pin — the exact rating depends on the number of adjacent pins carrying current simultaneously.
