USB Connector — Type A B C Mini Micro Female Male PCB Mount & Panel Socket

USB Connectors — Type A, B, Mini, Micro & USB-C Female/Male PCB Mount & Panel Sockets

USB (Universal Serial Bus) connectors are the world's most widely used interface standard for data transfer, device communication, and power delivery. From the original USB Type-A to the modern USB-C, USB connectors are specified in virtually every electronic device, embedded system, industrial controller, and consumer product. This collection provides the complete USB connector ecosystem for PCB design, panel mounting, cable assembly, and repair — covering all standard USB connector types in both female (receptacle) and male (plug) configurations, across all generations from USB 1.1 to USB 3.2 and USB4.

USB Connector Buying Guide

Step 1 — Identify connector type: Type-A is rectangular (host side). Type-B is square (device side, printers). Mini-B is trapezoidal (5-pin, older devices). Micro-B is thin trapezoidal (5-pin, most common device side 2010–2019). Type-C is oval and reversible (current standard).

Step 2 — USB 2.0 vs USB 3.0: USB 2.0 Type-A has 4 pins; USB 3.0 Type-A has 9 pins (backward compatible). USB 3.0 connectors are typically blue. For data rates above 480Mbps (USB 2.0 max), use USB 3.0 or USB-C connectors.

Step 3 — Choose mounting style: SMT for reflow soldering on modern PCBs. DIP for hand soldering and prototyping. Right-angle for edge-accessible ports. Panel mount for chassis-mounted USB ports accessible from outside an enclosure.

Step 4 — USB-C considerations: USB-C receptacles vary in supported protocols (USB 2.0 only, USB 3.2, USB4, PD). Verify the specific product's supported protocols match your application. For USB Power Delivery designs, ensure the receptacle is rated for the required current (up to 5A for 100W PD).

Frequently Asked Questions

Q: What is the difference between USB Micro-B and USB-C?
A: Micro-B is a 5-pin asymmetric connector (must be inserted in the correct orientation). USB-C is a 24-pin reversible connector that supports higher data rates (USB 3.2, USB4), higher power delivery (up to 240W), and alternate modes (DisplayPort, Thunderbolt). USB-C is the current standard; Micro-B remains widely used in legacy and industrial applications.

Q: Are USB 2.0 and USB 3.0 Type-A connectors physically compatible?
A: Yes. USB 3.0 Type-A plugs and receptacles are backward compatible with USB 2.0. A USB 3.0 plug fits in a USB 2.0 receptacle and vice versa, but the connection will operate at USB 2.0 speeds.

Q: What is the mating cycle rating for Micro-USB connectors?
A: Standard Micro-B USB connectors are rated for ≥1,500 mating cycles per the USB specification. Reinforced Micro-B variants with stronger shell retention are rated for ≥5,000 cycles. For high-cycle applications, consider USB-C which is rated for ≥10,000 cycles.

Q: Do you stock USB-C connectors that support USB Power Delivery?
A: Yes. Our USB-C receptacles include variants rated for up to 5A current, suitable for USB PD designs up to 100W (20V × 5A). For USB PD implementation, additional PD controller ICs are required on the PCB.

Q: What is a USB breakout board used for?
A: USB breakout boards convert the USB connector's pins to standard 2.54mm (0.1") pin headers, providing easy access to VBUS, D+, D−, GND (and additional USB 3.0/C signals) for prototyping, testing, and development without custom PCB design.
