Needs validationhigh risk
Package matches, but lower capacitance is a functional downgrade requiring engineering review.
Best Alternatives to TAJD476K025RNJ
TAJD476K025RNJ is a 47µF 25V tantalum capacitor in a 7343 D-case. Alternatives exist but require careful review of package size, capacitance, or voltage rating before substitution.
AI replacement insight
Package riskhigh
Some candidates are taller (E-case) and will not fit in a space designed for a D-case.
Electrical riskhigh
Candidates may have lower voltage or capacitance, requiring circuit re-evaluation.
Sourcing risklow
Alternatives are available from the same manufacturer family (AVX TAJ series).
Can it be replaced directly?
No direct, risk-free replacement is available. All candidates have significant differences in package size or electrical parameters.
Best replacement path
Upgrade voltage and verify package height (e.g., TAJE476K035RNJ) or accept lower capacitance in the same package (e.g., TAJD336K025RNJ).
Main risk
Package mismatch (height) and electrical downgrades (voltage, capacitance) are the primary risks.
