A strong alternative with identical package and ratings, but wider 20% tolerance.
TAJD107K020RNJ is a 100µF 20V tantalum capacitor in a 7343 D-Case package. When seeking alternatives, focus on matching capacitance, package, and ensuring voltage rating is equal or higher while checking tolerance.
Wider tolerance can affect timing or filtering performance.
Some alternatives have a taller package that may not fit.
No direct drop-in replacement with identical specifications has been identified. The closest options require verifying tolerance (TAJD107M020RNJ) or package dimensions (TAJE107M025RNJ).
The closest alternative is TAJD107M020RNJ, which matches all key parameters except for a wider tolerance (20% vs 10%).
The main risks are accepting a wider capacitance tolerance or a physically taller package, which could impact circuit performance or board assembly.

|---|---|---|---|---|---|
| Package | 7343 (D Case) | 7343 (D Case) | 7343 (E Case) | 7343 (D Case) / 7343 (E Case) — Identical package and footprint.; TAJE107M025RNJ: Candidate is taller (4.1mm vs 2.9mm). | |
| Voltage | 20V | 20V | 25V | 20V / 25V — Identical voltage rating.; TAJE107M025RNJ: Higher voltage rating provides more margin. | |
| Capacitance | 100 µF | 100 µF | - | 100 µF — Identical capacitance. | |
| Tolerance | 10% | 20% | 20% | 20% — Wider tolerance may affect circuit precision.; TAJE107M025RNJ: Wider tolerance may affect circuit precision. | |
| Esr | 500 mOhms | - | 300 mOhms | 300 mOhms — Lower ESR is generally better. |
TAJD107M020RNJ is a strong functional alternative with the same package, voltage, and capacitance, but a wider 20% tolerance. If your design can accept this, it is the best option. For a voltage upgrade, TAJE107M025RNJ offers 25V but has a taller package and wider tolerance.
