Is there a pin-compatible replacement for LN2220PAR?

Currently, no replacement has been verified as 100% pin-compatible without review. HFP6291LR-G1 shares the same package and electricals, making it a likely candidate, but pinout must be checked.

What risks should I check before replacing LN2220PAR?

Key risks include pinout differences, which could damage the board. Also, check for subtle differences in control logic (e.g., PWM vs. PFM modes) that might affect efficiency or noise in your specific application.
