Needs validationmedium risk
Murata 0805 X7R matches 10uF, 25V, and temp range but needs redesign checks.
Best Alternatives to CA45-B-25V-10uF-K
CA45-B-25V-10uF-K is a 10uF 25V Case B tantalum capacitor. Listed MLCC options need footprint and circuit validation.
AI replacement insight
Electrical riskhigh
ESR, leakage, ripple, and DC bias are not aligned.
Package riskhigh
Candidates are 0805/1206 MLCC, not Case B.
Firmware risklow
Passive capacitor; no firmware interface.
Sourcing riskmedium
Some lifecycle fields are unknown.
Can it be replaced directly?
No pin-compatible replacement is confirmed from the provided evidence.
Best replacement path
Prefer a Case B 10uF 25V tantalum with matched ESR/leakage; MLCCs require redesign review.
Main risk
The main risk is replacing a Case B tantalum with a different MLCC footprint and ESR profile.
