0.40 mm Pitch, 34-Position Mezzanine Receptacle for Tight Board Stacks
The Molex 5055503420 is a 34-position receptacle from the SlimStack 505550 series, designed for board-to-board mezzanine stacking at a mated height of 0.8 mm. The 0.016" (0.40 mm) pitch and dual-row layout pack 34 circuits into a compact footprint, suited for portable devices and space-constrained PCBs where every millimeter of board edge matters.
The 0.40 mm pitch demands a PCB fab capable of fine-line routing between pads; typical via-in-pad or microvia techniques are expected for breakout.
