No direct pin-compatible replacement is supported by the provided data. Listed MLCC options require footprint and circuit validation.

AI replacement insight

Electrical riskhigh

MLCC ESR and bias behavior differ.

Package riskhigh

All candidates differ from 3528 B.

Sourcing riskmedium

One close Murata option is NFND.

Can it be replaced directly?

No pin-compatible replacement is verified.

Best replacement path

For redesign, start with 1210 MLCC candidates, then validate ESR, DC-bias capacitance, and pads.

Main risk

Package and capacitor technology differ from the 3528 B tantalum target.
