Is there a pin-compatible replacement for ES2JW?

Yes, ES2JW from FUXINSEMI is a strong candidate for a pin-compatible replacement. It is in the same SOD-123FL package and has the same electrical characteristics. US2MW is also pin-compatible but requires review.

What risks should I check before replacing ES2JW?

The main risk is using a diode with a slower reverse recovery time (trr), which can cause overheating and failure in high-frequency circuits. Always verify the substitute's trr is ≤ 35ns.
