Is there a pin-compatible replacement for RT6200GE?

Several candidates share the SOT-23-6 package, but none are confirmed pin-to-pin compatible without verifying the pin functions and electrical parameters. Pinout verification is required.

What risks should I check before replacing RT6200GE?

Key risks include lower maximum input voltage, different switching frequencies requiring external component changes (inductor, capacitors), and potential differences in control loop stability.

RT6200GE Alternatives, Datasheet & Cross Reference | RICHTEK

The RT6200GE is a high-voltage (36V), 0.6A step-down DC-DC converter in a SOT-23-6 package. Finding a replacement requires careful matching of input voltage, switching frequency, and pinout.

AI replacement insight

Electrical riskhigh

All candidates have lower max input voltage and different switching frequencies.

Package risklow

All candidates use the same SOT-23-6 package, but pinout must be verified.

Can it be replaced directly?

No direct, drop-in replacement for the RT6200GE has been identified. All candidates require electrical and pinout verification.

Best replacement path

AOZ1280CI is the closest functional alternative, but requires verifying the application's maximum input voltage is below 26V.

Main risk

The primary risk is the lower maximum input voltage of all available alternatives, which may not be suitable for applications requiring the full 36V range.

Recommended alternatives

A functional alternative with higher current, but a lower max input voltage (26V) and different switching frequency.
