What This USB-A Receptacle Does on the Board
The Amphenol 73725-11A0RLF is a USB 2.0 Type-A receptacle, 4 contacts, in a right-angle through-hole package. It's the board-mount half of a standard USB-A connection — the port you see on a PC, monitor, or industrial panel.
Ratings That Decide the Fit
Rated 2.5 A per contact, which covers standard USB power delivery for peripherals drawing up to 500 mA per the USB 2.0 spec, plus some headroom for charging. The 1500 mating cycle rating means this port will survive daily plug/unplug in a lab or production test fixture for years — it's not a one-and-done connector. The gold and GXT™ contact finish is what enables those 1500 cycles without the contacts wearing through to base metal.
Through-hole, right-angle mounting. The four signal pins and the two shield tabs (for the shell ground) all solder into the PCB. The board lock — a pair of plastic or metal posts — snaps into the board before soldering, holding the connector square during reflow. The vertical mounting feature (the connector body sits upright relative to the board edge) means the USB plug inserts straight into the panel cutout.
