Micro-USB Type-B

Micro-USB Type-B has a compact, low-profile form distinct from Mini-USB Type-B.

Also called Micro USB Micro-B Micro USB B

Check for the extra section before calling a connector Micro-B.

Look for

A narrow Micro-B form and the wider SuperSpeed Micro-B form are separate records. Look at the entire opening rather than a cable’s label alone.

Recognition, not measurement. Each drawing is fitted independently: equal boxes do not mean equal sizes. Contact detail is deliberately omitted.

01 / Cable-end plugExterior side study
Micro-USB Type-B: cable-end plug, exterior side study. Shallow metal plug exterior; housing is not the mating face. Not to scale; no pinout.

Cable extends to the right; exterior only.

Qualitative recognition study interpreted from the pictured manufacturer example. Inner contacts, exact dimensions and hidden surfaces are omitted.

Two things to notice

  1. Shallow metal plug exterior
  2. Housing is not the mating face

What the picture cannot tell you

Do not identify this from size on screen. Compare the reference label and exact product; no latch or contact layout is prescribed here.

No receptacle drawn: a sufficiently clear, role-specific opening was not visually inspected for this pilot. Do not infer it by mirroring the plug.

Sources, drawing scope & rights

Visual references checked 2026-10-09. These are new, source-scoped recognition studies, not approved mechanical drawings, pinouts or compatibility verdicts. Independent drawing review remains pending.

The useful distinction

Recognize it. Then verify it.

Micro-USB Type-B has a compact, low-profile form distinct from Mini-USB Type-B. [C006A]

USB-IF compliance guidance specifies five contacts for Micro-B connectors; the contact count does not establish charger behavior, USB generation or cable quality. [C006B]

Molex specifies 1051640001 as a Micro USB-B USB2 receptacle, 5 loaded circuits and 1 row(s), with mating-interface pitch 0.65mm. [C006W]

Identify the documented form

Identify the single narrow Micro-B form before choosing a legacy cable.

  1. Micro-B is a distinct compact, low-profile form rather than a synonym for Mini-B. S001
  2. The wider two-part SuperSpeed Micro-B profile is a separate form: inspect the whole opening. S001

Keep this limit: The documented contact count establishes neither charging behavior nor a cable’s quality or negotiated mode. S363

Make the next check

Read the device connector name and its required data or charging function.

Existing source inspection and AI review remain distinct from independent technical review. A matching form does not establish a safe connection.

Recorded variant and source limits
  • No V54 contact numbering or electrical assignment map is published.
  • Charging behavior, negotiated data mode and cable quality remain outside connector identification.
  • USB 2.0 Micro-B receptacle/plug (5 contacts): Contact numbers only; spatial order unverified.
  • USB 2.0 Micro-B receptacle: Contact numbers per Type-C R2.5 Table 3-20.
  • USB 2.0 Micro-B plug: Contact numbers per Type-C R2.5 Table 3-18.
  • Prior view context (not a source-view value): Contact count only in V54; no numbered mating-face map is reproduced.

Before you connect

What to check

  1. Confirm whether the wide companion section is present.
  2. Check the device’s connector name in its manual.
  3. Treat charge behavior and data support as separate questions.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

Micro-B is not the wider SuperSpeed Micro-B.

The five-contact statement is scoped to the USB 2.0 Micro-B construction in the USB-IF compliance notice. Contact counting is not a wiring map or evidence of an installed device’s charging behavior.
