0.35 mm Pitch, 48-Position Mezzanine Plug
The Molex 5050704822 is a 48-circuit plug from the SlimStack 505070 series, designed for board-to-board mezzanine stacking. With a 0.014" (0.35mm) pitch and a mated stack height of 0.6mm, this connector suits high-density signal interconnects where board real estate is tight — think smartphone internals, wearable PCBs, or compact camera modules. The 0.019" (0.48mm) height above board keeps the profile low enough for sandwich-style assemblies. The dual-row arrangement packs 48 positions into a narrow footprint, demanding a fine-pitch PCB layout and a controlled reflow profile for the SMT solder joints. Pick-and-place features and solder retention pads are built into the body, so the part handles automated assembly without extra fixturing. The outer shroud contacts protect the signal pins during handling and alignment.
Stack Height and Board Fit
The mated stacking height of 0.6mm is the critical dimension for the mezzanine gap — your board stack design must clear this to avoid shorting components on the opposing board. The 0.48mm height above board on the plug side means the receptacle half (not listed here) will add the remaining height to reach the full 0.6mm stack. At 0.35 mm pitch, routing signals between the pads requires a PCB fab capable of 0.175 mm trace/space or finer. This is not a connector for coarse-pitch prototyping — it belongs in a production design with controlled impedance and fine-line etching.
Sourcing and Compliance
The base product number 505070 covers the SlimStack family; the -4822 suffix identifies this specific 48-position, 0.35 mm pitch variant.
