USB Mini-AB receptacle: roles, views and source limits

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

Mini-AB: recognize the receptacle role. A recessed opening in a mounted housing distinguishes the Mini-AB receptacle role from a projecting cable plug. Outline and inner tongue are coarse role cues; exact geometry and contacts are omitted. — A recessed opening in a mounted housing distinguishes the Mini-AB receptacle role from a projecting cable plug.

Mini-AB: identify the form, then the exact part. A historical port symbol is kept separate from the exact Würth five-contact horizontal SMT receptacle identity. The silhouette uses TI’s historical example, not an uninspected Würth drawing. — A historical port symbol is kept separate from the exact Würth five-contact horizontal SMT receptacle identity.

What the studies help distinguish

The exact Würth identity is source-documented; drawing pixels were not acquired.

No pitch, family-wide envelope or current-device compatibility is inferred.

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

No pitch, family-wide envelope or current-device compatibility is inferred.
Conceptual role and recognition cues only. Follow the exact part drawing for dimensions, contacts and mating requirements.
