34-Circuit Ultra-Fine-Pitch Mezzanine Receptacle
The Molex 5046183410 is a 34-position receptacle from the SlimStack 504618 series, designed for board-to-board mezzanine stacking where vertical space is at a premium. It uses a center strip contact arrangement across two rows at a 0.014" (0.35mm) pitch — one of the tightest pitches in the SlimStack family, which means the board footprint needs careful routing to keep traces between pads. The mated stack height is just 0.024" (0.61mm), so this connector fits into ultra-slim portable devices, handheld instrumentation, or any assembly where the gap between parallel PCBs is under a millimeter.
Solder Retention for SMT Reliability
The connector includes solder retention features — small metal tabs on the body that reflow to the board pads. On a 0.35 mm pitch part with 34 surface-mount tails, those tabs take the shear load from cable strain or thermal cycling off the signal joints. Without them, the fine-pitch solder joints are vulnerable to cracking during board handling or in equipment that sees moderate vibration.
