Rubycon 50PX330MEFC10X16 matches value and size but has shorter life.
ERS1HM331G16OT is a radial 330uF 50V aluminum electrolytic capacitor. No candidate here is verified pin-compatible; review package, life, ESR and ripple.
C and voltage match, ESR/ripple not fully checked.
Most candidates are SMD, not radial.
Passive capacitor, no firmware impact.
Some lifecycle fields are unclear.
No verified pin-compatible replacement is supported by the provided data.
Start with Rubycon 50PX330MEFC10X16 if 2000h life is acceptable after FAE review.
Package and lifetime differences dominate the risk.
