The MUR460RLG is a popular 600V/4A ultrafast rectifier. While no direct drop-in replacements were found, several functional alternatives with superior electrical ratings are available if a board layout change is possible.

AI replacement insight

Package riskhigh

No candidates match the target's axial package. Board redesign is mandatory.

Electrical risklow

Most candidates meet or exceed key electrical ratings (V, I, trr), but should be verified.

Can it be replaced directly?

No direct pin-compatible replacement for the MUR460RLG in its DO-201AD axial package was identified. All potential alternatives require a different PCB footprint.

Best replacement path

For new designs or redesigns, parts like onsemi's MUR860G offer similar or better electrical performance in a common TO-220 package.

Main risk

The primary risk is mechanical incompatibility; all reviewed alternatives are in larger power packages (like TO-220) and are not drop-in replacements for the axial DO-201AD package.
