Needs validationhigh risk
Parametric alternative with a lower max input voltage (40V vs 60V); other key specs match.
Best Alternatives to LM2596HVS-3.3(UMW)
The LM2596HVS-3.3(UMW) is a high-voltage (60V) 3A step-down regulator. Alternatives exist but often have a lower 40V input rating or different switching frequencies, requiring careful review of application requirements.
AI replacement insight
Electrical riskhigh
Most alternatives have a lower 40V max input voltage vs the target's 60V.
Package risklow
The TO-263 package is common, and pinouts are often standard within a family.
Can it be replaced directly?
No, there is no direct drop-in replacement for the LM2596HVS-3.3(UMW). All alternatives require compromises on input voltage, output current, or switching frequency, necessitating design review.
Best replacement path
For applications under 40V, LM2596S-3.3(UMW) is a strong candidate. For >40V, review the lower-current LM2575HVS-3.3(UMW) and verify load requirements.
Main risk
Maximum input voltage mismatch; most alternatives are standard 40V parts, while the target is a high-voltage 60V part.
