Finding a substitute for the Richtek RT9193-25GB, a 2.5V 300mA LDO in a SOT-23-5 package, requires careful review of pinout and electrical parameters. Several functional alternatives exist with minor differences.

AI replacement insight

Electrical riskmedium

Pin 4 function (Bypass) is critical for performance in some circuits.

Package risklow

Most candidates use the same SOT-23-5 package. One requires footprint check.

Can it be replaced directly?

Direct replacement for RT9193-25GB should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

RT9013-25GB-MS offers matching voltage and higher current in the same package, but requires review of the pin 4 function.

Main risk

The primary risk is the pinout difference on pin 4, where the target's Bypass (BP) pin is replaced by a No Connect (NC) on alternatives, potentially impacting noise and stability.
