Board-Stacking Fit for a Tight Z-Budget
The Molex 0524653071 is a 30-position receptacle from the SlimStack 52465 series, built for board-to-board mezzanine stacking on a 0.80mm pitch. It uses a dual-row, center-strip contact arrangement and surface-mount termination. The 0.140" (3.55mm) height above board, combined with three mated stacking heights of 4.5mm, 5.65mm, and 7mm, lets you pair it with different header heights to match the z-height clearance in the enclosure.
Stack Height Options and What They Mean
The 0524653071 receptacle mates with the corresponding SlimStack header to achieve one of three board-to-board gaps: 4.5mm, 5.65mm, or 7mm. The header height determines the final stack — pick the header that gives the clearance you need between boards. The 0.80mm pitch keeps the footprint compact, but the routing channels between pads are narrow; a four-layer board with a solid ground plane underneath helps control impedance and reduces crosstalk on the outer rows.
