USB micro AB Receptacle, Shielded, 10,000-Cycle Rating
The Amphenol FCI 10104111-0001LF is a USB micro AB receptacle — a 5-contact, USB 2.0-rated connector in a shielded, right-angle SMT package. The steel and stainless shell provides EMI containment for the data pair, and the gold-plated contacts are rated for 1.8 A per contact at 100 VAC. The 10,000 mating cycle rating is the standout spec here: it is five times the USB 2.0 baseline of 1,500 cycles, making this part a fit for equipment that sees frequent plug-unplug duty — test fixtures, handheld instruments, or panel-mount access ports where the connector lives through the product life.
Shielding and Construction
The solder retention feature on the SMT pads holds the connector to the board during reflow and adds shear resistance against cable strain. The gray insulation color is standard for micro AB receptacles, visually distinguishing it from the black micro B version.
This is a USB micro AB receptacle — it accepts both micro A and micro B plugs. The difference between micro A and micro B is the plug shape: micro A plugs are typically used for OTG host devices, while micro B plugs are the standard peripheral-side connector. The 10104111-0001LF is USB 2.0 only — it is not electrically compatible with USB 3.0 or 3.1 signaling rates, though a USB 3.0 micro B plug will physically insert. For USB 3.0 applications, look for a connector with the additional SuperSpeed contacts.
