A strong polymer alternative with better voltage/ripple specs, but lower capacitance that must be verified.
Best Alternatives to KNH2470UF35V149EC0017
Finding a substitute for the KNSCHA KNH2470UF35V149EC0017, a 470µF 35V polymer capacitor, requires matching its low ESR and high ripple current. Alternatives exist but may involve tradeoffs in capacitance or technology type.
AI replacement insight
Electrical riskhigh
Target is a polymer capacitor; substituting with standard electrolytic types is a major downgrade.
Package risklow
The 10x13mm radial package is common, and several candidates match the form factor.
Can it be replaced directly?
No direct drop-in replacement with identical key parameters was found. The closest candidates require engineering review, primarily for capacitance or technology type differences.
Best replacement path
Consider NJCON 3310501013R00 if a 30% reduction in capacitance is acceptable, as it offers superior voltage and ripple current with similar low ESR.
Main risk
The main risk is substituting a standard electrolytic capacitor, which will have much higher ESR and lower ripple current handling than the target polymer capacitor, potentially causing circuit failure.
