USB Micro AB Receptacle for OTG and Dual-Role Ports
The Molex 475890001 is a USB micro AB receptacle — the connector that lets a portable device negotiate whether it acts as a USB host or a peripheral. Unlike a standard micro B jack, the AB variant accepts both micro A and micro B plugs, which is what makes On-The-Go (OTG) operation possible. It carries 5 contacts in a single shielded shell, rated for 30VAC and a dual current spec of 1A and 1.8A — the higher figure likely corresponds to the VBUS pin under a specific duty cycle or temperature condition.
SMT Assembly and Pick-and-Place Ready
This receptacle is designed for automated assembly: it's surface-mount, right-angle orientation with a bottom-mount, horizontal footprint. The steel/stainless shell provides the shielding needed to pass FCC/EMI radiated emissions testing on the USB differential pair.
Mating Cycles and Field Reliability
The 10,000-cycle rating is the strongest durability spec on this connector. A typical micro USB B receptacle is good for about 5,000 cycles per the USB-IF specification; this part doubles that. The gold contact finish is what makes the extra cycles possible — tin-plated contacts would fret and oxidize well before 10,000 mates. For a handheld device that gets charged once a day, 10,000 cycles works out to over 27 years of daily use.
