Is there a pin-compatible replacement for TAJC476K016RNJ?

No. Currently, no pin-compatible replacements with the same key parameters have been identified. Candidates in the same package size have significantly different capacitance or voltage ratings, making them unsuitable.

What risks should I check before replacing TAJC476K016RNJ?

Before replacing TAJC476K016RNJ, you must verify the substitute's package size, as no alternatives fit the same footprint. Also, check if the higher ESR of most candidates is acceptable for your circuit's performance.

TAJC476K016RNJ Alternatives, Datasheet & Cross Reference | AVX

Finding a substitute for the AVX TAJC476K016RNJ, a 47µF 16V tantalum capacitor in a C-case, requires careful review. While functional alternatives exist, there are no direct pin-compatible replacements, making package size the primary challenge.

AI replacement insight

Package riskhigh

No candidates match the 6032 C-Case footprint, requiring a board redesign.

Electrical riskmedium

Most alternatives have higher ESR, which could impact performance. Careful analysis is required.

Sourcing risklow

The TAJ series is widely available from AVX, but specific part availability varies.

Can it be replaced directly?

There are no direct, drop-in replacements for TAJC476K016RNJ. All potential substitutes have different physical packages or electrical parameters.

Best replacement path

TAJD476K016RNJ is the closest electrical match but requires a larger D-case footprint. If voltage margin is desired, TAJD476K025RNJ is also an option.

Main risk

The primary risk is package incompatibility. All functional alternatives are in larger cases (D or E) and will not fit the target's C-case footprint.

Recommended alternatives

Electrically similar but in a larger package, requiring a board redesign.
