The Molex 5046182010 is a 20-circuit receptacle from the SlimStack 504618 series, designed as a board-to-board mezzanine interconnect. With a 0.014" (0.35mm) pitch and 0.6mm mated stacking height, it targets ultra-thin portable electronics where every tenth of a millimeter of z-height matters. The center strip contact arrangement and gold plating suit signal-level duty in compact, high-density layouts — think smartphone mainboard-to-display or battery management interconnects where the board stack is tight and the signal count is moderate.
The 0.35mm Pitch — What It Means for Board Layout
At 0.35mm pitch, this is a fine-pitch connector. The board footprint needs controlled impedance routing between pads — standard 0.5mm or 0.4mm design rules won't clear the escape traces without necking down. The 20 positions split across two rows keep the connector body narrow, but the real constraint is the PCB fab's ability to route between pads on inner layers. If your layout engineer hasn't routed a 0.35mm-pitch BGA-style footprint before, this connector will force a design review.
Obsolete — Sourcing Reality for the 5046182010
If you're populating a new BOM, the active sibling 504618-2010 is the same part in bulk packaging with an active lifecycle status — worth checking against your assembly house's preferred packaging format.
This is a surface-mount receptacle — no through-hole, no crimp.
