What This 0.80mm-Pitch Mezzanine Receptacle Does
The Molex 0524652470 is a 24-position receptacle from the SlimStack 52465 series, built for board-to-board mezzanine stacking at a 0.80mm pitch. The 0.80mm pitch keeps the footprint tight, but it also means the board traces between pads need careful routing; this is not a connector for power distribution, it is a signal-only interconnect. The receptacle is surface-mount only, with a board guide molded into the housing that helps align the part during reflow and takes shear loads off the solder joints once mated. The height above board is 3.55mm, and the mated stacking heights span 4.5mm, 5.65mm, and 7mm — three options from one receptacle footprint, which gives the layout engineer some flexibility in board spacing without requalifying the connector.
What tin does not handle well is repeated mating and unmating; the oxide layer that forms on tin builds up with each cycle and increases contact resistance. If your design calls for field-serviceable boards that get disconnected and reconnected multiple times, a gold-plated sibling in the SlimStack family would be the safer call.
Active Production — No Lifecycle Surprises
There is no last-time-buy notice or phase-out on record. The base product number is 052465, and the full order code 0524652470 is the current production configuration.
How the Stacking Heights Line Up
The receptacle mates with a matching SlimStack 52465 header to achieve one of three mated stacking heights: 4.5mm, 5.65mm, or 7mm. The same receptacle footprint works across all three — the height difference comes from the header side. That means you can standardize on this one receptacle P/N for a product family that uses different board spacings, as long as you swap the header to match the target stack height.
