# USB-C plug > 24-pin reversible plug designed to replace all other USB plugs by carrying all USB data protocols (and some others) and power levels (up to 240 W, in either direction) **Wikidata**: [Q52635267](https://www.wikidata.org/wiki/Q52635267) **Source**: https://4ort.xyz/entity/usb-c-plug ## Summary The USB-C plug is a 24-pin reversible connector designed to replace all previous USB plug types. It serves as a universal interface capable of carrying all USB data protocols, alternate modes like Thunderbolt and DisplayPort, and power levels up to 240 watts in either direction. ## Key Facts * **Pin Configuration:** Features a 24-pin design that allows for reversible plug orientation. * **Power Delivery:** Supports power levels up to 240 W, capable of flowing in either direction. * **Replaces:** Supersedes older connectors including USB 3 Standard-A/B, USB 2 Standard-A/B, USB Micro-A/B, and USB Powered-B plugs. * **Publisher:** Standardized and maintained by the USB Implementers Forum. * **Official Names:** Formally identified as "USB Type-C plug" and "USB-C plug." * **Variants:** Exists in three specific forms: Full-Featured (high-speed data + power), USB 2 (legacy data + power), and Power-Only (no data). * **Compatibility:** Connects specifically with USB-C receptacles. ## FAQs ### Q: Is the USB-C plug reversible? A: Yes, the USB-C plug utilizes a 24-pin symmetrical design that allows it to be inserted into a receptacle in any orientation, eliminating the "right-side up" requirement of legacy USB plugs. ### Q: What specific connectors does the USB-C plug replace? A: It is designed to replace all previous USB plugs, including USB Standard-A, Standard-B, Micro-A, Micro-B, and Powered-B connectors across both USB 2 and USB 3 generations. ### Q: Are all USB-C plugs capable of transmitting video and high-speed data? A: No. While the "Full-Featured" plug supports high-speed data and alternate modes like DisplayPort, specific variants like the "USB 2 Type-C plug" and "USB Type-C Power-Only plug" omit the connections required for high data rates or data transfer entirely. ## Why It Matters The USB-C plug represents a fundamental consolidation in connectivity standards, addressing the long-standing fragmentation of USB cables and ports. By introducing a reversible 24-pin interface, it solved a major usability frustration associated with earlier USB generations. Its significance lies in its universality; it is designed to function across virtually all device categories, from smartphones to laptops, carrying not just data but sufficient power (up to 240 W) to charge high-performance electronics. This standardization reduces electronic waste by minimizing the need for device-specific cables and supports a wider ecosystem of protocols, including Thunderbolt and DisplayPort, through a single physical connector. The shift to USB-C simplifies the user experience by consolidating power, data, and video into one durable, bidirectional plug. ## Notable For * **Reversibility:** Being the first USB plug design that can be inserted either right-side up or upside down. * **Power Capacity:** Supporting a significantly higher power threshold (up to 240 W) compared to previous USB standards, enabling charging for larger devices. * **Protocol Agnosticism:** Acting as a physical vessel for non-USB protocols, specifically Thunderbolt and DisplayPort, in its Full-Featured variant. * **Universal Consolidation:** Being the singular connector intended to unify all previous USB form factors (Standard, Micro, Mini). ## Body ### Design and Specifications The USB-C plug is defined as a 24-pin reversible-plug serial digital connector. Its symmetrical pinout allows users to insert the plug without checking orientation. It is a subclass of the broader USB-C connector system and the USB plug category. The standard is managed by the USB Implementers Forum, which dictates that the plug connects to a matching USB-C receptacle. ### Functional Variants While the physical shape is consistent, the internal wiring of the plug varies based on usage requirements: * **USB Full-Featured Type-C plug:** This is the comprehensive version that replaces all other USB plugs while supporting the highest data rates, USB4, Thunderbolt, DisplayPort, and power up to 240 W. * **USB 2 Type-C plug:** A cost-reduced version that replaces legacy USB 2 plugs. It maintains the 240 W power capability but omits the pins required for SuperSpeed data rates (USB 3/4) and video protocols. * **USB Type-C Power-Only plug:** The simplest variant, used strictly for power delivery up to 240 W. It omits all data connections and is prohibited for use in detachable cables, restricted to dongles and captive cables. ### Market Replacement The USB-C plug was engineered to obsolete a wide range of legacy connectors. It officially replaces the USB 3 Standard-A, Standard-B, Powered-B, Micro-A, and Micro-B plugs, as well as their USB 2 predecessors (Standard-A, Standard-B, Micro-A, Micro-B). It is distinct from the USB-C receptacle, which is the port on the host device. ## References 1. [Source](https://www.usb.org/usb-type-ctm-cable-and-connector-specification) 2.
