3-pin Mini-XLR versus full-size 3-pin XLR

Are you looking at the compact Mini-XLR/Tini-QG form or a full-size XLR connector? Matching three-pole counts do not make the shells interchangeable.

Computer-generated illustration, not a photograph. — P309 · Connector3-pin Mini-XLR (Switchcraft Tini-QG) connector

How they differ

3-pin Mini-XLR (Switchcraft Tini-QG) connector Confirm the compact Mini-XLR/Tini-QG form and 3-conductor variant; do not substitute it for full-size XLR or infer a wiring scheme from pole count.
3-pin XLR connector Check pole count, mating side and the equipment function. This record only covers the three-pole recognition form and does not publish a pinout.
