0.40 mm pitch, 60-position board-to-board receptacle for mezzanine stacking
The Molex 2049270601 is a 60-circuit receptacle from the SlimStack 204927 series, built for dense board-to-board mezzanine interconnects. The 0.016" (0.40mm) pitch and dual-row layout pack 60 positions into a compact footprint — the tight pitch drives the PCB routing density and fab capability, so verify your board house can hold 0.40 mm trace-and-space before committing the layout. Mated stacking height is 3 mm, which sets the board gap in the assembly; the 0.066" (1.68mm) height above board gives the profile clearance under the top board. Gold contact finish signals signal-level duty: the plating is for corrosion resistance and reliable low-level circuit contact, not for power throughput. The part carries pick-and-place and solder retention features, meaning it runs on a standard SMT line with vacuum pickup and holds position during reflow without secondary hand-soldering.
