Is there a pin-compatible replacement for LM2675M-5.0(UMW)?

No direct pin-compatible replacement has been verified. Candidates like LM2594M-5.0(UMW) share the same SOP-8 package, but their different switching frequencies mean they are not drop-in replacements without reviewing the surrounding circuit.

What risks should I check before replacing LM2675M-5.0(UMW)?

The main risk is the difference in switching frequency (260kHz for the original vs. 150kHz for most alternatives), which impacts external component selection (inductor, capacitors) and EMI performance. Always verify the pinout and thermal performance before substitution.
