Part Datasheet Review and Validation

flux

Reviewed USB4155-03-C_REVA against GCT’s official information and added the official product-spec link to the project’s Implementation Details because the available project-property editor did not expose a dedicated Datasheet URL field.
Key findings
  • MPN: USB4155-03-C_REVA / GCT USB4155-03-C
  • Manufacturer: GCT / Global Connector Technology
  • Description: USB 3.2 Gen 2 Type-C plug, horizontal side-entry, SMT edge-mount
  • Contacts: 24 signal/power contacts + 2 shell/shield pads visible in this Flux part
  • Ratings: 48 VDC, 5 A summary, 240 W, -30 °C to +85 °C, 10,000 mating cycles
  • Footprint: appears to include the expected 24 SMT pads plus shell pads/stakes for the edge-mount connector
Mismatches / flags
  • No pin-number mismatches found: A1–A12, B1–B12, S1/S2 match the expected USB-C plug pinout.
  • No component-review errors/warnings were reported.
  • Minor metadata gap remains: the project has MPN but no visible Manufacturer Name, Package/Case, or dedicated Datasheet URL property in the editable project-property schema I had available.
  • Datasheet URL was persisted as Implementation Details: https://gct.co/download?name=usb4155-spec.pdf&type=PDFSpecification
Suggested next steps:
  1. Add explicit Manufacturer Name / package metadata if those fields become available.
  2. Run a mechanical footprint check from the official drawing before publishing.
  3. Add pin descriptions for each terminal if you want richer library documentation.
