The GCT USB4105-GF-A is a USB Type-C receptacle from the USB4105 series, designed for USB 2.0 applications on printed circuit boards.

This model uses horizontal SMD mounting, also described as right angle, with side entry and PCB top mount positioning. The metallic shell uses through-hole stakes, providing improved mechanical retention compared with purely SMD connectors.

The product configuration provides 16 functional contacts, while it is also commercially listed as a 24-position connector, 16 plus 8 dummy. It is suitable for equipment using the USB-C physical interface but requiring only USB 2.0 communication, compatible power input or data connection.

The GCT specification lists a collective current rating of 5A on VBUS pins, 6.25A on GND pins, 1.25A on VCONN and 0.25A per pin on the remaining contacts. Voltage rating is 48V DC and listed power rating is 240W, always depending on the complete circuit, USB-C implementation, cable, power supply and controller used.

With stainless steel shell, black LCP UL94V-0 housing, copper alloy contacts and Gold Flash contact plating, the USB4105-GF-A is suitable for compact electronics, portable devices, development boards, modules, industrial products and compatible PCB repair.

Important note

Before purchase, always confirm the complete reference, PCB footprint, mounting position, connector orientation, number of contacts, pin position, mechanical retention points, profile height, PCB drawing compatibility and electrical circuit requirements.

Although it uses the USB-C format, this connector is intended for USB 2.0. Compatibility with USB 3.x / SuperSpeed connections should not be assumed without confirming the circuit and the correct connector.

The listed 240W power rating refers to the connector capacity under specified conditions. To use high voltage and current over USB-C, the complete system must be compatible, including control circuit, CC configuration, power supply, cable, protection, thermal design and applicable standards.

This item corresponds only to the GCT USB4105-GF-A connector. PCB, USB-C cable, USB controller, Power Delivery controller, external components, solder and accessories are not included unless expressly stated otherwise.
