IEC 62680-1-3:2018

Overview

IEC 62680-1-3:2018 - Universal serial bus interfaces for data and power - Part 1‑3: Common components - USB Type‑C™ Cable and Connector Specification defines the mechanical, electrical and functional requirements for USB Type‑C receptacles, plugs and cables. Published as the third edition (2018), this IEC adoption of the USB‑IF Type‑C specification specifies the new reversible connector, cable assemblies, legacy adapters and the detection/configuration mechanisms that allow Type‑C to interoperate with existing USB 2.0, USB 3.1 and USB Power Delivery (USB PD) based systems.

This standard is intended as a supplement to existing USB specifications and provides normative requirements to ensure interoperability of Type‑C components; informative material may illustrate design examples.

Key topics and technical requirements

• Connector and receptacle definitions: electro‑mechanical dimensions and performance requirements for the USB Type‑C plug and receptacle to ensure reliable mating and longevity.
• Cable assemblies: requirements for Full‑Featured Type‑C cables, USB 2.0 Type‑C cables, captive cables and cable construction guidance for signal and power carrying capabilities.
• Legacy compatibility: specifications for Type‑C to legacy (Standard‑A, Standard‑B, Micro‑B, Mini‑B) cable assemblies and adapters to preserve backward compatibility.
• Device detection and configuration: Type‑C attach/detach detection, plug orientation (flip) and cable twist detection, initial role establishment (source/host vs sink/device) and data/charging setup.
• Power handling: guidance on VBUS usage and USB Power Delivery optimization when used with the Type‑C connector, including VCONN considerations.
• Interoperability focus: normative clauses to achieve component interoperability and informative sections that illustrate implementation options.
• Testability and performance: mechanical performance and electrical behavior expectations required for compliant manufacturing and certification.

Applications and who uses this standard

• Device manufacturers integrating USB Type‑C ports (smartphones, laptops, tablets, peripherals).
• Cable and connector designers, contract manufacturers and component suppliers producing compliant Type‑C plugs, receptacles and cables.
• System integrators and OEMs designing power delivery and data interfaces.
• Test labs, compliance and certification bodies verifying interoperability with USB 2.0 / USB 3.1 and USB PD.
• Accessory makers creating legacy adapters and Type‑C accessories.
