Product details

Board Layout Fit — 0.35mm Pitch and 0.8mm Stack Height

The Molex 5052702012 is a 20-position receptacle from the SlimStack Armor 505270 series, built for parallel board-to-board mezzanine stacking. The 0.014" (0.35mm) pitch on two rows demands a tight board layout — trace-and-space below 0.18mm is typical for routing between pads. The mated stacking height is 0.8mm, with the receptacle sitting 0.027" (0.68mm) above the board surface. That z-height budget is fixed by the mating header's own height; verify the header part number against the 0.8mm stack spec before committing the BOM line.

Contact Plating and Assembly Features

The receptacle includes Pick and Place and Solder Retention features, which means it handles automated SMT placement and holds position during reflow without secondary adhesive. Tape & Reel packaging aligns with high-volume pick-and-place lines.
