Smaller, Reversible USB Type-C Connector is Ready for Production

The USB 3.0 Promoter Group has announced the completion of the USB Type-C specification that defines the next generation USB connector.

The USB Type-C specification establishes a new cable and connector scheme tailored to fit mobile device product designs, yet robust enough for laptops and tablets. With this release, the specification has been transferred to the USB Implementers Forum (USB-IF) for ongoing management and the establishment of a compliance and certification program.

“Interest in the USB Type-C connector has not only been global, but cross-industry as well,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “Representatives from the PC, mobile, automotive and IoT industries have been knocking down our door anticipating this new standard. This specification is the culmination of an extensive, cooperative effort among industry leaders to standardize the next generation USB connector as a long-lasting, robust solution.”


The USB Type-C specification defines the physical USB Type-C cable and connector form factor along with the functional requirements for detecting and managing USB connections over an extensible wiring architecture. This new cable and connector supports USB performance at SuperSpeed USB 10 Gbps (USB 3.1) and USB Power Delivery up to 100W.

Key characteristics of the USB Type-C connector include:
● Entirely new design
o Tailored for emerging product designs
o Robust enough for laptops and tablets; slim enough for mobile phones
o Similar to size of USB 2.0 Micro-B

● Usability enhancements
o Reversible plug orientation and cable direction

● Supports scalable power charging
● Future scalability
o Designed to support future USB performance needs


● Mechanical specs:
o Receptacle opening: ~8.4mm x ~2.6mm
o Durability: 10,000 cycles
o Improved EMI- and RFI-mitigation features
o Power delivery capacity: 3A for standard cables and 5A for connectors

The new USB Type-C plug and receptacle will not directly mate with existing USB plugs and receptacles (Type-A, Type-B, Micro-B, etc.); however, the USB Type-C specification defines passive new-to-existing cables and adapters to allow consumers to use the new connector with their existing products.
