Needs validationmedium risk
AZ431LBNTR-G1 is the closest listed AZ431L option if 1% accuracy is acceptable.
Best Alternatives to AZ431LANTR-G1
AZ431LANTR-G1 is a 1.24V adjustable shunt regulator. The closest listed option is same-series AZ431LBNTR-G1 with lower accuracy.
AI replacement insight
Electrical riskmedium
accuracy, ref voltage, and bias current vary
Package riskmedium
SOT23 names align, but pinout is unverified
Firmware risklow
analog reference part
Sourcing riskmedium
some lifecycle fields are dash only
Can it be replaced directly?
No pin-compatible replacement is verified from the supplied evidence.
Best replacement path
Use AZ431LBNTR-G1 only if 1% initial accuracy is acceptable and pinout is confirmed.
Main risk
Pinout is missing and several candidates use a 2.5V reference instead of 1.24V.
