Board-to-Board Receptacle, 0.40mm Pitch, 34 Circuits
The Molex 5024263410 is a 34-position receptacle from the SlimStack 502426 series, using a center strip contact arrangement across two rows. Mated stack height is 0.039" (1.00mm), so the paired boards sit close together, saving z-height in slim enclosures.
Obsolete — No Official Replacement Listed
The 5024263410 is marked obsolete by Molex. No direct successor order code has been assigned to this specific position count and pitch variant. For a BOM line that still calls out this part, the options are last-time-buy inventory through the surplus channel or a board redesign around a current-production SlimStack or alternative fine-pitch mezzanine connector.
This receptacle mates with the matching SlimStack 502426 header at the same 0.40mm pitch and 34-position count to achieve the 1mm mated stack height. The gold-on-gold contact interface is suited for signal-level currents where contact resistance stability matters more than bulk current capacity. The 2-row layout means the footprint is a narrow double row of pads — routing breakout traces between the 0.40mm pads requires a fine-line PCB capability.
