SlimStack 501594 — 22-Position Plug at 0.40mm Pitch
The Molex 5015942211 is a 22-circuit plug from the SlimStack 501594 series, designed for board-to-board stacking in space-constrained portable electronics. The 0.016" (0.40mm) pitch and dual-row layout pack the 22 positions into a compact footprint, while the 0.9mm mated stacking height suits thin-profile assemblies where the z-axis budget is tight. Gold-plated contacts (4.00µin) on the mating interface handle the signal duty in low-voltage digital paths — the flash-grade gold is adequate for the limited mating cycles typical of a production build, not a field-service reconnect.
The 0.028" (0.71mm) height above the board on this plug side gives a low profile for the solder joint clearance under the component.
Obsolete Status and Sourcing Path
The 5015942211 is listed as Obsolete in the manufacturer's lifecycle record. No official successor part number is published for this exact order code. No direct cross-reference from another brand is on record; a pin-compatible alternative would need to match the 0.40mm pitch, 22 positions, 0.9mm stack height, and surface-mount termination.
