IEC 62680-1-3:2026

Overview

IEC 62680-1-3:2026 is the internationally recognized standard published by the IEC that defines the technical requirements for USB Type-C® cable and connector interfaces. This seventh edition details the electro-mechanical specifications for USB Type-C receptacles, plugs, and cable assemblies. The standard's primary aim is to enhance user convenience and support modern device design, ensuring compatibility with both current and legacy USB technologies.

This specification is guided by key design principles: enabling slim, high-performance device form factors; maintaining seamless operation with existing USB components; and reducing user confusion by supporting reversible plug orientation. IEC 62680-1-3:2026 supersedes the 2024 edition, incorporating all approved editorial changes and technical updates as of Revision 2.4 of the USB-IF Universal Serial Bus Type-C Cable and Connector Specification.
