A 10µF 20V capacitor in the same B-case with improved voltage and lower ESR.
Best Alternatives to CA45A-B-16V-10uF-K
Finding a substitute for the CA45A-B-16V-10uF-K, a 10µF 16V solid tantalum capacitor in a B-case, involves matching key electrical parameters. Several alternatives offer upgraded voltage or lower ESR, providing potential drop-in replacements after careful review.
AI replacement insight
Electrical riskmedium
Candidates have varying ESR and tolerance. A higher ESR or wider tolerance can impact circuit stability and performance.
Package risklow
Most candidates use the same B-case package, but one uses a non-compatible A-case, requiring a layout change.
Sourcing risklow
Alternatives are available from multiple manufacturers, but regional availability may vary.
Can it be replaced directly?
Direct replacement for CA45A-B-16V-10uF-K should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The strongest candidate is CA45-B-20V-10uF-K from TORCH, which offers a higher voltage rating and lower ESR in the same package.
Main risk
The primary risk when substituting is selecting a part with higher ESR or wider tolerance, which can degrade circuit performance, especially in power filtering applications.
