USB4105-GF-A Guide


I’ll research the USB4105-GF-A from manufacturer and distributor primary sources, then create the requested application and usage guide with verified citations and clearly marked unknowns.
The manufacturer product page and product specification are identified. I’m now extracting the exact pin mapping, ratings, land-pattern constraints, and USB-C integration requirements.

USB4105-GF-A Application and Usage Guide
The USB4105-GF-A is a 16-contact, right-angle, top-mount USB Type-C receptacle intended for USB 2.0 data and USB-C power connections. Its common use is as a reversible USB-C device/charging port, with duplicated D+/D− and power contacts supporting either plug orientation while CC1 and CC2 establish the port role and attachment state.
Verification note: GCT’s product page explicitly lists USB4105-GF-A as an orderable variant, while the attached product specification is written for the broader USB4105 series. Values cited from that specification therefore apply at series level; mechanical footprint dimensions must be checked against the exact USB4105-GF-A product drawing before fabrication.
1. Quick Specifications
Created and verified the USB4105-GF-A Application and Usage Guide. It includes cited specifications, pinout guidance, USB-C sink/source integration, PCB layout practices, pitfalls, alternatives, and sourcing information; unverified footprint compatibility is explicitly identified.
