A 330µF, 63V capacitor in an identical 10x20mm radial package. Performance must be verified for drop-in use.
Find alternatives for the Rubycon 63ZLJ330M10X20, a 330µF 63V low-impedance radial capacitor. Key considerations for replacement are matching the 10x20mm case size and performance characteristics like ESR and ripple current.
Many alternatives have different physical dimensions.
ESR and ripple current are critical for ZLJ series and must be verified.
No drop-in replacement has been verified. AISHI ERJ1JM331G20OT is a strong candidate with an identical form factor and key ratings, but requires datasheet comparison of performance specs like ESR and ripple current.
Prioritize candidates with a 10mm diameter radial package and 330µF/63V rating, then verify ESR and ripple current from datasheets.
The main risk is physical incompatibility from a different package size or electrical incompatibility from mismatched ESR or ripple current ratings.
