48393-0003

Molex 48393-0003: USB 3.0 Type-A receptacle, right angle, through-hole.

Molex 48393-0003 is a USB 3.0 (5 Gbps) Standard-A receptacle, right angle, through-hole, with a 4.00 mm contact height, blue housing and 15 microinch gold contacts.

Lifecycle: Molex lists this part as Not Recommended For New Design (checked 2026-10-17, replacement: contact Molex). Distributors still stocked it on that date. Check availability, or plan an alternative, before using it in a new design.

Pins

Design notes

• Pins 1 to 4 (VBUS, D-, D+, GND) carry USB 2.0; pins 5 to 9 carry the SuperSpeed pairs (StdA_SSRX-, StdA_SSRX+, GND_DRAIN, StdA_SSTX-, StdA_SSTX+). Names follow the Molex pin table.
• Molex gives only the drill sizes. The annular rings (1.2 mm on the 0.70 mm holes, 1.2 x 2.4 / 1.2 x 2.1 mm ovals on the shell slots) were chosen for this footprint. The hole and slot pattern was cross-checked against the KiCad stock footprint USB3_A_Molex_48393-001 and is identical.

3D model

The 3D model is AI-created from the manufacturer drawing, not a manufacturer model. The manufacturer's own model is not redistributed (its download terms grant no redistribution right). Stainless shell drawn as a rectangular tube 13.10 x 5.72 mm (opening 12.50 x 5.12 mm on the 4.00 mm centre line) with a closed rear, side flanges to 13.80 mm, 4 legs; blue housing base and tongue (11.10 mm wide); 4 USB 2.0 and 5 SuperSpeed contact strips; 9 straight tails 0.50 x 0.30 mm to 1.10 mm below the PCB. No latch dimples, springs, logo or date code.

• Frame: Adom Z-up, millimetres, seating plane z = 0, origin = footprint origin, identity footprint binding. Extents: 13.80 x 14.25 x 6.86 mm above the PCB, tails to -1.10 mm.
• Cross-check against the manufacturer model (not included): Molex/TraceParts STEP envelope 13.80 x 14.25, shell top 6.86 mm above the PCB, tails to -1.10 mm: matches.
• Virtual MPN mark (identification aid, not a claim about the real part's marking): On the shell top. Dark mark, because the body there is light stainless steel (the etch gate warns on a dark mark by rule and accepts it on a light body). Placed with adom-aiflow-etch; the plan and gate report are in provenance/etch/.
