USB-A Receptacle for USB 3.2 Gen 1 — 9 Contacts, Vertical Mount
The Molex 0484080003 is a USB-A (USB TYPE-A) receptacle from the 48408 series, designed for USB 3.2 Gen 1 (formerly USB 3.0 / SuperSpeed) operation at 5 Gbps. Its 9 contacts break down as four legacy USB 2.0 pins plus five SuperSpeed signal pairs — a layout that mates with any standard USB-A plug but only achieves full Gen 1 throughput when the cable and host controller also support the higher data rate. The vertical through-hole orientation places the receptacle upright on the board, a common choice for panel-mount or edge-mount applications where the cable enters perpendicular to the PCB. The shell is shielded with steel, stainless material for EMI containment, and the blue insulation color is the standard visual identifier for USB 3.0-compatible receptacles.
Dual Current Rating — Signal vs. Power Pins
The current rating is split: 0.25A per contact on the signal pins and 1.8A on the power pins. This is a standard USB 3.0 derating — the high-speed differential pairs are not designed for power delivery, while the VBUS and GND pins can handle the 900 mA (0.9A) required by USB 3.0 for bus-powered devices, with margin. Do not expect this connector to carry the 3A+ of USB Battery Charging or Power Delivery; those applications require a dedicated power-rated USB-C or custom interconnect.
Board Lock and Mechanical Retention
Without these locks, the solder joints on the signal pins alone would fatigue over 5000 cycles. The through-hole mounting further strengthens the mechanical bond compared to an SMT-only footprint.
Operating Range and Flammability
For applications requiring V-0 or V-2 rated housings, check the Molex 48408 series for alternate material options.
