Mini-USB Type-B vs Micro-USB Type-B

Mini-B and Micro-B are different connector forms. Similar names do not make their plugs or receptacles interchangeable.

How they differ

Mini-B and Micro-B are distinct USB forms; similar names and matching nominal counts do not make their shells interchangeable.

  • Mini-USB Type-B is not a synonym for Micro-USB Type-B. Compare the complete outline and the device’s designation. S001 · S001
  • Micro-B is the compact, low-profile form in this comparison. The wider compound SuperSpeed Micro-B belongs to another reference. S001 · S001

What this comparison does not establish: Micro-B contact count does not establish charging, negotiated mode or cable quality. S363

Illustrations are computer-generated with prior AI visual review; independent technical and rights review pending. A comparison is not a compatibility verdict.

This comparison stays within one evidence layer.

All selected records are Connector records. Similar layer does not mean compatible, interchangeable or safe to mate.

Mini USB-B versus Micro USB-B. A deeper-profile miniature plug nose. A shallower-profile micro plug nose. Not to scale; no pinout or compatibility verdict.

Where the difference lies

What to verify next

Shell profile is the observation. Both shown from the cable exterior side.

Read the exact port name in the device documentation. Do not trial-fit or treat the housings as a scale comparison.

Inspect the figure-level references and rights

Inspected 2026-10-09. Original Port & Cable vector diagram; first-party sources linked for inspection only, no third-party graphics bundled. No manufacturer image, CFA logo or licensed photograph is copied into this package. No approval for fabrication, mating, wiring or publication is implied.
