The 55510-150LF: Surface-mount receptacle, 50 positions in two rows on 2.00mm pitch — the row spacing is also 2.00mm, so the footprint is a uniform 2.00mm grid. The 0.177-inch (4.50mm) insulation height sets the z-height budget above the board; the push-pull fastening means the mating header needs no latch, just a straight insertion and pull.
Current and Thermal Limits
Rated 2A per contact at 200V — the current ceiling is conservative for a 2.00mm pitch connector with phosphor bronze contacts.
