SlimStack 502426 — 24-Circuit Mezzanine Receptacle
The Molex 5024262410 is a 24-circuit receptacle from the SlimStack 502426 series, a board-to-board mezzanine interconnect family built for dense parallel stacking. The 0.016" (0.40mm) pitch and 1mm mated stack height place it in the ultra-fine-pitch segment — the footprint demands a tight PCB layout and the mating half must be a matching SlimStack header at the same 1mm stack height.
What 0.40mm Pitch and Gold Flash Mean for the Build
The 4.00µin gold flash on the contacts is a signal-grade finish: it prevents oxidation in storage and during the first few mating cycles, but the thin plating will wear through faster than a 15µin or 30µin gold deposit if the board sees repeated disconnect/reconnect in the field. This connector is designed for a one-time or occasional mate in production, not a field-serviceable harness connection.
