A functional alternative in the same package, but with a reduced maximum input voltage of 40V.
Best Alternatives to LM2576HVR-5.0
The LM2576HVR-5.0 is a high-voltage (60V) 3A step-down regulator. Alternatives often have a lower 40V input rating, requiring careful verification of system voltage.

Electrical riskhigh
Input voltage mismatch is a critical failure point.
Package risklow
Many alternatives share the same TO-263-5 package.
Sourcing riskmedium
The high-voltage 'HVR' version may be less common than standard 40V parts.
Can it be replaced directly?
No direct, drop-in replacement with a 60V input rating was found among common alternatives. Many parts are pin-compatible but have a lower 40V rating.
Best replacement path
If input voltage is below 40V, use a standard LM2576S-5.0. If 60V is required, a direct replacement is necessary as no upgrade path is identified.
Main risk
The most significant risk is substituting a 40V-rated part into a system that requires the target's 60V input capability, which could lead to device failure.
