A strong alternative with the same package and capacitance, but a higher voltage rating and lower ESR.
TAJC227K006RNJ is a popular 220µF 6.3V tantalum capacitor from AVX in a C-case (6032) package. Finding a suitable replacement involves matching capacitance, voltage, and package size.
Low if capacitance and tolerance are matched. Higher voltage is generally safe.
Many similar part numbers exist in different case sizes (C, D, E); verify footprint.
The AVX TAJ series is widely available from multiple distributors.
TAJC227K010RNJ is a strong candidate for direct replacement, sharing the same package, capacitance, and tolerance, with improved electrical characteristics.
Upgrade to TAJC227K010RNJ for higher voltage rating (10V) and lower ESR (0.5Ω) in the same package.
The main risk when substituting is selecting a part with a different package or capacitance value, which can cause assembly issues or circuit malfunction.
