Is there a pin-compatible replacement for TAJA226K010RNJ?

Currently, no pin-compatible, drop-in replacement has been identified. All suitable alternatives are in different physical packages and require changes to the circuit board layout.

What risks should I check before replacing TAJA226K010RNJ?

The main risk is the package size; you must verify your PCB can accommodate a larger part. Also, check if the new part's ESR and tolerance are acceptable for your application's stability and performance.

TAJA226K010RNJ Alternatives, Datasheet & Cross Reference | AVX

TAJA226K010RNJ is a popular 22uF 10V AEC-Q200 tantalum capacitor from KYOCERA AVX in a compact 1206/A-Case package. Finding a direct drop-in replacement is challenging due to its specific size.

AI replacement insight

Package riskhigh

All reviewed alternatives are in larger packages, requiring a mandatory PCB layout change.

Electrical risklow

Candidates offer higher voltage, but differences in ESR or tolerance require circuit validation.

Can it be replaced directly?

No direct pin-for-pin replacement was identified. All candidates require a change in the PCB layout due to different package sizes.

Best replacement path

The best path is a board redesign to accommodate a slightly larger B-Case (1210/3528) capacitor like TAJB226K016RNJ, which offers a higher voltage rating.

Main risk

The primary risk is the physical package mismatch. No candidates fit the original 1206/A-Case footprint.

Recommended alternatives

A functional alternative with a higher voltage rating (16V), but in a larger 1210/B-Case package.
