Likely drop-in replacement with same package and capacitance, plus a higher voltage rating.
Find the best replacements for the AVX TAJA336K006RNJ, a 33µF 6.3V 1206 tantalum capacitor. We've analyzed pin-compatible upgrades and functional alternatives.
Many alternatives are in larger 1210 or 2917 packages and are not drop-in.
Most candidates have equal or better voltage and capacitance ratings.
TAJA336K010RNJ is a strong candidate for direct replacement, featuring an identical package and improved voltage rating.
The most direct path is TAJA336K010RNJ, which is a likely pin-compatible upgrade. Other options require board layout changes.
The main risk is physical incompatibility. Many functional alternatives are in larger packages and will not fit a 1206 footprint.

Likely drop-in replacement with same package and capacitance, plus a higher voltage rating.
| Feature / factor | TAJA336K006RNJ | TAJA336K010RNJ | TAJD336K025RNJ | TAJD336K035RNJ | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 3216 (1206) | 1206 (3216 Metric) | 7343 (2917 Metric) | 2917 (7343 Metric) | 1206 (3216 Metric) / 7343 (2917 Metric) / 2917 (7343 Metric) — Same case size (A Case).; TAJD336K025RNJ: Candidate package is much larger.; TAJD336K035RNJ: Candidate package is much larger. |
| Capacitance | 33 µF | 33 µF | 33 µF | 33 µF | 33 µF — Capacitance matches.; TAJD336K025RNJ: Capacitance matches.; TAJD336K035RNJ: Capacitance matches. |
| Voltage | 6.3 V | 10 V | 25 V | 35 V | 10 V / 25 V / 35 V — Higher voltage rating provides more margin.; TAJD336K025RNJ: Significantly higher voltage rating.; TAJD336K035RNJ: Significantly higher voltage rating. |
| Tolerance | 10% | 10% | - | - | 10% — Tolerance matches. |
| Esr | 2.2 Ω | 1.7 Ω | - | - | 1.7 Ω — Lower ESR is generally favorable. |
TAJA336K010RNJ is an excellent alternative, offering the same 1206 package and 33µF capacitance with a higher voltage rating (10V) and lower ESR.
