Is there a pin-compatible replacement for LMR16030PDDAR?

No candidate has been confirmed to be a 100% pin-compatible replacement without engineering review. TPS54360DDAR uses the same HSOIC-8 package and is functionally similar, making it the most likely candidate for pin compatibility, but you must compare the pin functions in both datasheets before replacing the part.

What risks should I check before replacing LMR16030PDDAR?

Before replacing LMR16030PDDAR, you must check three main risks. First, ensure the substitute's input voltage rating is at least 60V. Second, verify the output current is 3A or more. Third, check the quiescent current (Iq) if your application is power-sensitive. Finally, always compare datasheet pinouts to ensure compatibility.

LMR16030PDDAR Alternatives, Datasheet & Cross Reference | Texas Instruments

Finding a substitute for the Texas Instruments LMR16030PDDAR, a 60V, 3A step-down regulator, requires careful comparison of key parameters. While several alternatives exist in the same HSOIC-8 package, they often involve trade-offs in input voltage, output current, or quiescen...

Electrical riskhigh

Candidates have different quiescent current, input voltage, or output current ratings.

Package riskmedium

While packages match, pinout and thermal pad differences must be verified via datasheet.

Can it be replaced directly?

No direct drop-in replacement for LMR16030PDDAR has been identified. The closest functional alternative, TPS54360DDAR, requires careful review of its quiescent current. All other candidates involve a downgrade in a critical parameter like input voltage or output current.

Best replacement path

The most promising alternative is TPS54360DDAR, which matches the input voltage and offers higher current. However, its higher quiescent current must be acceptable for the application.

Main risk

The main risks when replacing LMR16030PDDAR are mismatched quiescent current, lower input voltage ratings, or reduced output current capability. Pinout compatibility must also be verified for any candidate.

Recommended alternatives

A functional alternative with matched input voltage and higher output current, but with significantly higher quiescent current.
