USB Mini-A plug: roles, views and source limits

Mini-A and Mini-AB were deprecated; this is historical identification.

Applies to: Original interpretation of the exact linked source examples; not a physical drawing or mating declaration.

Mini-A: recognize the historical cable plug. A protruding broadly rectangular metal-shell symbol is linked to the Mini-A plug labeled in TI’s historical illustration. The source shows a broadly rectangular Mini-A plug face; contacts are omitted.

Mini-A versus Mini-B: compare the plug faces. The TI-labeled Mini-A and Mini-B plug examples are compared using a rectangular versus tapered coarse face cue. The examples are different labeled plug forms; the outlines are not insertion templates.

Your next useful observation

Record the actual connector role and exact product marking, then use the linked source view. Do not derive a missing dimension or contact pattern from these drawings.

Keep these limits

  • These role cards do not supply contact geometry or modern OTG capability.
  • Conceptual role and recognition cues only. Follow the exact part drawing for dimensions, contacts and mating requirements.
