Nexperia USA Inc.
A form-fit alternate from the same manufacturer with a higher voltage rating but weaker forward voltage.
PMEG2010AEH,115 is a 20V, 1A Schottky rectifier from Nexperia in a compact SOD123F package. It is optimized for high-efficiency applications thanks to its very low forward voltage drop.
Higher forward voltage in all candidates increases power loss and heat.
Nexperia candidates share the same SOD123F package. Other candidates have different packages.
No guaranteed drop-in replacement has been identified. The closest options, like PMEG4010CEH,115, have a higher forward voltage which will increase power loss and may require thermal analysis.
PMEG4010CEH,115 from the same manufacturer offers a similar profile with an upgraded voltage rating, but its higher forward voltage must be reviewed.
The primary risk when replacing PMEG2010AEH,115 is increased power dissipation due to substitutes having a higher forward voltage (Vf).

| Forward Voltage | 380mV @ 1A | 490mV @ 1A | 540mV @ 1A | 490mV @ 1A / 540mV @ 1A — Higher Vf increases power loss. Review thermal impact.; PMEG4010EH,115: Significantly higher Vf increases power loss. Review thermal impact. |
The best alternative is likely PMEG4010CEH,115. It is from the same manufacturer in the same package and offers a higher voltage rating. However, you must verify if its higher forward voltage (490mV vs 380mV) is acceptable for your application's power budget.
