The Molex 465571545 is a 40-position, 4-row high-density array receptacle from the SEARAY 46557 series. It is a female SMT connector designed for board-to-board stacking applications where signal density and a low profile matter. Typical use is in mezzanine or parallel-board interconnects inside telecom, server, or industrial control equipment.
Stacking Height Flexibility
This connector supports seven mated stacking heights: 10mm, 10.5mm, 11mm, 11.5mm, 12.5mm, 13mm, and 15mm. That range lets the designer choose the board-to-board spacing after the footprint is fixed — the same receptacle works across multiple enclosure z-height budgets. The 0.317" (8.05mm) height above board is the receptacle's own body height; the total stack depends on the mating male header height.
Assembly and Placement
The connector includes a board guide and pick-and-place features, which simplify automated SMT assembly. The board guide aligns the part during placement, and the pick-and-place surface lets the nozzle handle it without disturbing the contacts. Tape & Reel packaging feeds directly into a pick-and-place machine.
