The Molex 5050662222 is a 22-position receptacle from the SlimStack Armor 505066 series, built for board-to-board mezzanine stacking where vertical space is tight. It uses a 0.014" (0.35mm) pitch across two rows of center strip contacts, with gold plating at 4.00µin (0.100µm) on the mating interface. The mated stack height lands at 0.6mm — that's the gap between the two PCBs once the header and receptacle are paired. This is a surface-mount part with pick-and-place and solder retention features, meaning it's designed to run through a reflow oven without shifting.
Board Layout and Stack-Up
The 0.35mm pitch is the tightest in the SlimStack Armor line — it forces a fine-pitch PCB footprint and limits routing density on inner layers. At 0.023" (0.59mm) above the board, the receptacle sits low enough to fit under a display or battery pack in a handheld device. The 0.6mm mated stack height means the total z-height budget between boards is under a millimeter, which is common in smartphone, wearable, and compact IoT modules. The dual-row arrangement gives 22 positions in a narrow body width, so the connector doesn't eat up board real estate on the x-axis either.
Cross-Shop Note
The alternate order code 505066-2222 carries identical specs — same 22 positions, same 0.35mm pitch, same 0.6mm mated height, same gold plating thickness. The difference is in the packaging suffix: the dash version may be listed under a different Digi-Reel® or cut-tape SKU depending on the distributor's inventory system. For a BOM line, either code lands the same connector body.
