Its 0.014\" (0.35mm) pitch and 0.6mm mated stacking height place it in the ultra-low-profile, high-density segment — the kind of connector that fits between stacked PCBs in a compact handheld or portable device where every tenth of a millimeter of z-height is budgeted. The gold layer prevents oxide buildup on the contact interface during the product's service life, not for repeated disconnect-reconnect cycles. This is a production-line detail that matters when the part runs through a high-speed SMT line. The 0.014\" (0.35mm) pitch is the tightest in the SlimStack 505070 series, meaning the pad layout on the PCB must match that spacing exactly — no room for routing a trace wider than a few mils between adjacent pads. That is low enough for a phone or wearable mainboard-to-daughtercard stack, but it also means the connector is not serviceable with standard tweezers — the gap is too small for hand probing. The 0.48mm standoff also leaves room for the solder fillet to form without bridging to adjacent pads.","metaTitle":"Molex SlimStack 5050704840, 48 Pos, 0.35mm Pitch","metaDescription":"Molex 5050704840 SlimStack plug, 48 positions, 0.014\" (0.35mm) pitch, 0.6mm mated height, gold contacts, SMT.
