CA45-A-35V-0.1UF-K is a 0.1uF 35V Case A tantalum/polymer SMD capacitor. Listed MLCCs are functional candidates only and need FAE review.

AI replacement insight

Electrical riskmedium

Voltage is adequate, ESR/leakage differ.

Package riskhigh

Case A footprint is not verified.

Firmware risklow

Passive part; no firmware interface.

Sourcing risklow

Candidates are active catalog matches.

Can it be replaced directly?

No pin-compatible replacement is proven from the provided evidence.

Best replacement path

Start with the 1206/3216 MLCC candidates, then verify footprint, ESR, leakage and bias behavior.

Main risk

Tantalum/polymer to MLCC substitution can change ESR, leakage, capacitance under bias and stability.
