470uF 50V radial candidate with same case size but lower capacitance and ripple rating.
Best Alternatives to ERS1VM102W20OT
ERS1VM102W20OT is a 1000uF 35V radial aluminum electrolytic capacitor. Current candidates require FAE review before use.
AI replacement insight
Electrical riskhigh
Kept candidates have lower capacitance or missing ripple/ESR.
Package riskmedium
Case size matches, but pinout/polarity is not verified.
Firmware risklow
Passive capacitor; no firmware interface.
Sourcing riskmedium
All kept parts are catalog matched, but not verified.
Can it be replaced directly?
No direct pin-compatible replacement is proven from the provided data.
Best replacement path
Start with same-case 50V candidates, then verify capacitance, ripple, ESR, life, and polarity.
Main risk
Electrical ratings do not match the 1000uF, 2210mA, 0.03 ohm target.
