The Molex 0536250874 is an 80-circuit plug from the SlimStack 53625 series, designed as the top half of a board-to-board mezzanine stack. It uses a 0.025" (0.64mm) pitch across two rows with gold-plated outer shroud contacts, surface-mounted to the PCB. The 6.00mm height above the board, combined with the supported mated stacking heights of 7mm and 13mm, makes this plug suitable for parallel-board interconnects where space is tight but signal count is high — think portable devices, display modules, or compact compute stacks where the board gap is fixed by enclosure walls.
The 0.64mm pitch drives the board layout
At 0.025" (0.64mm) pitch, this plug demands a fine-line PCB trace and via pattern. The 80 positions on two rows mean the footprint is narrow along the mating axis but long across the row axis — about 25.6mm of linear board edge for the contact row.
Mating half and stacking height flexibility
The supported mated stacking heights of 7mm and 13mm give two distinct board-spacing options from the same plug — the height is set by the receptacle's standoff, not this part. That dual-height support is unusual for a single plug SKU; it means one BOM line can serve two enclosure depths if the receptacle side is swapped.
Gold contacts and SMT termination
The SMT termination is reflow-friendly, and the Tape & Reel packaging suits automated pick-and-place lines. No through-hole anchor pins; the Solder Retention feature is the sole board-attach aid.
