0.35mm Pitch, 40-Position Mezzanine Plug — Tight Board-Stacking Fit
The Molex 5052744042 is the 40-circuit plug half of the SlimStack Armor 505274 series, a board-to-board mezzanine interconnect built for dense, low-profile stacking. Its 0.014" (0.35mm) pitch and 0.026" (0.65mm) height above board let it fit into tight z-axis budgets common in portable devices, handheld instrumentation, and compact IoT modules.
Gold Plating and SMT Features — Automated Assembly Ready
No hand-solder rework is intended.

There is no last-time-buy window or official successor on record — standard RFQ sourcing applies. The base product number 505274 covers the SlimStack Armor family; the -4042 suffix specifies the 40-position, gold-plated, tape-and-reel variant.
