USB 2.0 Type-A Receptacle for Panel-Mount or Board-Edge Duty
It carries 4 contacts rated at 2.5 A each, which is the standard current limit for a USB 2.0 downstream port — enough for charging and data sync on a single port, but not for a high-power hub or fast-charge circuit. The shell is shielded with a copper alloy, which ties to the board ground plane to keep radiated emissions from the USB differential pair inside the chassis. A board lock on the mounting tabs anchors the connector during reflow and resists the shear force from repeated cable plug/unplug cycles — without it, the solder joints at the through-hole tails would fatigue over time in a panel-mount application.
The contacts are finished with Gold, GXT™ plating, rated for 1500 mating cycles.
Together, these ratings tell the compliance engineer that this part is accepted for use in UL-listed industrial control panels and ITE equipment.
No official cross-reference or direct second-source is on record; the 73725-1110BLF is a functional peer with identical specs and the same active status, but it is the same manufacturer and series.
