Stacked USB-A Receptacle for High-Density Panel Designs
The Molex 484090003 is a stacked USB Type-A receptacle from the 48409 series, packing two USB 3.2 Gen 1 (USB 3.1 Gen 1 / Superspeed USB 3.0) ports into a single vertical through-hole package. With 18 contacts total — nine per port — it delivers the full SuperSpeed signal set plus power and ground on each stack. The blue insulation color is standard for USB 3.0-compatible connectors, giving a quick visual identifier on the board.
What the Dual Current Rating Means for Your BOM
The connector carries two current ratings: 0.25A per contact on the signal pins and 1.8A on the power pins. That split is typical for USB 3.x receptacles — the four SuperSpeed differential pairs (eight signal contacts) are rated for signaling current only, while the VBUS and GND pins handle the 1.8A load. If your design draws the full 1.8A on the power rail, confirm the PCB trace width and the mating plug's current rating match; the connector itself is not the bottleneck at this level. The voltage rating is 30VAC/DC.
Shielding and Board Lock for Reliable USB 3.2 Gen 1
The steel and stainless shell provides continuous EMI shielding across the mated interface.
