The 55510-026: The 0.177" (4.50 mm) insulation height sets the mated stack height for the board-to-board pair — check the mating header's standoff against this clearance before layout. Applications listed include general purpose, industrial, and medical.
For BOM continuity, confirm the mating header's pitch and position count — any replacement will require a 2.00 mm pitch, 26-position dual-row receptacle with matching SMT footprint. Available through independent distribution channels.
Contact Plating and Current Capacity
The 2 A per-contact rating is conservative for signal-level loads; derate above 85°C ambient per the series derating curve.
