The TE Connectivity 1-2201196-0 is a 10-position plug from the Fine Pitch series, using outer shroud contacts in a 2-row layout at 0.40 mm pitch. This is a surface-mount mezzanine connector designed for parallel board stacking — the 0.75 mm height above board and 0.98 mm mated stack height put it in the ultra-low-profile range, suited for compact handheld or portable electronics where z-height is tight. The gold contact finish at 4.00 µin is a flash plating, which handles the occasional mating cycle of a production assembly or field-swap board but isn't specced for repeated reconnect duty in a service bay.
At 0.40 mm pitch, this connector demands tight trace routing and a controlled impedance stack-up if you're running high-speed signals. The 2-row arrangement gives 10 circuits in a narrow footprint — the outer shroud contacts provide some mechanical alignment during mating, but the real registration comes from the board's own solder pads.
