Is there a pin-compatible replacement for GAQY211G2S?

Yes, several parts like GAQY212G2S share the same SOP-4 package and 1 Form A pinout. However, none are electrically identical, with key differences in load current and on-resistance.

What risks should I check before replacing GAQY211G2S?

The main risk is the lower load current rating of alternatives. You must verify your circuit's maximum current does not exceed the replacement's limit. Also check for increased power dissipation due to higher on-resistance.
