TL432 is a 1.24 V adjustable shunt reference. Alternatives must match SOT-23 pinout, bias current, voltage range, and temperature.

AI replacement insight

Electrical riskmedium

Check Vref grade, Zka, and bias current.

Package riskmedium

SOT23 names vary by vendor.

Firmware risklow

No firmware interface.

Sourcing riskmedium

Many candidates are not indexed.

Can it be replaced directly?

MCC TL432-TP has the best reported pinout match, but it is not indexed.

Best replacement path

Use indexed AZ431LANTR-G1 for sourcing review or ingest MCC TL432-TP for pinout-based review.

Main risk

Unverified pinout is the main replacement risk.
