The Molex 0528850874 is an 80-position receptacle from the SlimStack 52885 series, designed as a board-to-board mezzanine interconnect. It uses a center strip contact arrangement on a 0.025" (0.64 mm) pitch in two rows, with a height above board of 0.165" (4.20 mm).
This receptacle supports mated stacking heights of 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm. The range covers common board-spacing budgets in portable designs — from slim 6 mm gaps in handhelds to 10 mm in slightly larger enclosures where component clearance on the underside matters.
Gold contact finish at 10.0 µin (0.25 µm) thickness is standard for moderate mating cycles in consumer electronics.
Mounting and Assembly Considerations
Surface mount termination with solder retention features — the extra pads on the connector body anchor the part during reflow and resist tombstoning from uneven paste deposition. The board guide aids optical alignment during pick-and-place. Tape & Reel packaging (also available in Cut Tape) feeds standard SMT lines without a feeder change.
