FFF CompatibilityDirect physical drop-in with identical SMT terminal footprint, pin pitch (0.50mm), shell width (8.94mm), and 4 through-hole shell retention legs.Same horizontal top-mount form factor, 16-pin USB 2.0 Type-C receptacle interface, and overall profile.Fully meets and exceeds electrical ratings (5A current rating, 48VDC rated voltage) and standard USB 2.0 pin assignment (VBUS, GND, CC1/CC2, D+/D-, SBU1/SBU2).Signal pins match the SMT pad footprint, but shell retention uses surface-mount tabs instead of 4 through-hole solder legs, requiring minor PCB layout adjustments on the grounding tabs.Same 16-pin horizontal top-mount USB Type-C receptacle form factor.Identical 16-pin USB 2.0 pin assignment and 5A current rating capability.
AI Summary

MC-311D by SOFNG: USB-C (USB TYPE-C) Receptacle Connector 16 Position Surface Mount.

The GCT USB4105-GF-A is a direct hybrid drop-in replacement for the SOFNG MC-311D-3C. It features the exact same 16-pin SMT signal terminal layout with 4 through-hole shell retention legs, horizontal orientation, 5A current rating, and 2.0 Type-C profile.

  • Available from major global distributors with full specification documentation and standard reel packaging
  • Offers higher mechanical mating durability (up to 20,000 mating cycles vs 8,500/10,000 cycles)
  • Identical pin layout, contact arrangement (USB 2.0 16-pin Type-C), and horizontal top-mount orientation

The GCT USB4110-GF-A provides identical USB 2.0 electrical performance and 16-pin SMT signal line spacing, but utilizes surface-mount shell retention tabs rather than through-hole shell legs. This makes it an excellent functional alternative if full surface-mount assembly is desired, though the PCB mounting hole footprint differs slightly.

  • Fully surface-mount design including shell retention tabs (no through-hole drilling required for shell legs)
  • Same 5A current rating and USB 2.0 16-pin Type-C electrical compatibility
  • Shell retention tabs are SMT rather than through-hole legs, requiring a footprint update for the shell grounding tabs

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
