The Molex 0548190511 is a USB - mini B receptacle from the 54819 series, designed for USB 2.0 OTG applications. It carries 5 contacts in a single port, rated at 1 A and 30 V — typical for USB 2.0 signal and low-power charging. The through-hole, right-angle mounting with a horizontal orientation places the port flush against the board edge, common for panel-mounted USB jacks on consumer devices like set-top boxes, printers, or portable equipment. The shielded copper alloy shell helps contain EMI within the 2.0 signal bandwidth, and the gold-plated contacts resist corrosion over repeated mating cycles.
No direct replacement or successor is listed. For a new design, consider active 54819-series variants or a different USB connector family with the same footprint — but no pin-compatible substitute is documented.
This orientation is standard for edge-mounted USB ports where the cable enters from the side of the enclosure.
