Pin-compatible substitute with identical ratings and a tighter ±10% tolerance in the same A-case package.
Best Alternatives to CA45-A-16V-4.7uF-M
Reviewing substitutes for the CA45-A-16V-4.7uF-M, a 4.7µF 16V tantalum capacitor in a standard A-case. Key considerations for replacement include matching the A-case (3.2x1.6mm) footprint, voltage rating, and capacitance stability.
AI replacement insight
Package riskmedium
Several candidates have different packages (B-case, 0603) and are not drop-in replacements.
Electrical riskhigh
Switching to MLCC or Polymer technology requires careful analysis of ESR and DC bias effects.
Can it be replaced directly?
Direct replacement for CA45-A-16V-4.7uF-M should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use CA45-A-16V-4.7uF-K for a direct fit or CA45-A-25V-4.7uF-K for an upgrade.
Main risk
The main risk is selecting a part with a different package size or technology (like MLCC) without engineering review.
