XY (Zhenhua Xinyun)
Needs validationhigh risk
Same-series 22uF 16V tantalum option, but package fit must be reviewed.
Best Alternatives to CA45-A-16V-22uF-K
CA45-A-16V-22uF-K is a 22uF 16V case A tantalum capacitor. Alternatives need package, temperature, and capacitor-technology review.
AI replacement insight
Electrical riskmedium
MLCC capacitance and ESR vary in circuit.
Package riskhigh
CA45-B and smaller MLCCs do not match case A.
Firmware risklow
Passive part; no firmware interface.
Sourcing riskmedium
Lifecycle is mostly unspecified.
Can it be replaced directly?
No confirmed pin-compatible replacement is proven from the provided evidence.
Best replacement path
For same footprint, review HGC1206R5226K250NSPJ if an MLCC is acceptable.
Main risk
The main risk is changing case size or replacing tantalum with X5R MLCC behavior.
