Is there a pin-compatible replacement for TAJD476K016RNJ?

Yes, TAJD476K025RNJ is a pin-compatible replacement for TAJD476K016RNJ. It uses the same 7343 D-Case package. Another option, TAJE476K035RNJ, has a compatible footprint but is taller, so it is not a guaranteed drop-in replacement without checking mechanical clearance.

What risks should I check before replacing TAJD476K016RNJ?

Before replacing TAJD476K016RNJ, you should check three main risks: 1) Package compatibility, as some alternatives are taller or have different footprints. 2) Electrical parameter changes, especially ESR, which can affect power supply ripple or stability. 3) Capacitance value, as significant deviations can alter circuit timing or inrush current.

AI replacement insight

Package riskmedium

Some alternatives have the same footprint but are taller (E-Case) or have a different footprint entirely (C-Case).

Electrical riskmedium

ESR and capacitance values vary across candidates. Higher capacitance or ESR can impact circuit stability and performance.

Sourcing risklow

The AVX TAJ series is widely available, with many options in the same family.

Can it be replaced directly?

Yes, TAJD476K025RNJ is a strong candidate for direct replacement, featuring the same D-case package and a higher 25V rating. However, its slightly higher ESR of 900mΩ (vs 800mΩ) should be verified.

Best replacement path

TAJD476K025RNJ is the best path, offering a higher voltage rating in the same package with only a minor ESR difference.

Main risk

The main risks when substituting are mechanical fit (package height) and electrical parameter changes like ESR or capacitance, which can affect circuit performance.

Recommended alternatives

Excellent upgrade with a higher voltage rating in the same package; verify slightly higher ESR.
