Can it be replaced directly?

Direct replacement for ME432AXG should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with TL432 low-voltage variants and verify pinout, bias current, and impedance.

Main risk

Pinout and low-current behavior are not verified.

Recommended alternatives

TL432 is a close 1.24V shunt-reference candidate for ME432AXG with pinout review required.
