KEMET
A potential pin-compatible alternative from KEMET with matching core specs but higher ESR.
Finding a substitute for the Vishay 293D475X9016A2TE3, a 4.7µF 16V tantalum capacitor, involves checking for pin-compatible options like the KEMET T491A475K016AT and evaluating functional alternatives with different packages or technologies.
For pin-compatible options, ESR and leakage current are the primary concerns. For others, voltage derating and DC bias effects are critical.
Many functional alternatives are in different packages, requiring a PCB layout change.
Direct replacement for 293D475X9016A2TE3 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path is T491A475K016AT, which matches the package and key electrical ratings. However, its higher ESR must be evaluated.
The main risk when substituting is mismatch in Equivalent Series Resistance (ESR), which can affect circuit stability and efficiency.

| Feature / factor | 293D475X9016A2TE3 | T491A475K016AT | T491C475K035AT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 3216-18 (A Case) | 3216-18 | 6032-28 | 3216-18 / 6032-28 — Package size matches target's A Case.; T491C475K035AT: Larger C Case requires PCB redesign. | |
| Voltage | 16.0 V | 16.0 V | 35.0 V | 16.0 V / 35.0 V — Voltage rating matches.; T491C475K035AT: Higher voltage rating provides more margin. | |
| Capacitance | 4.7e-06 F | 4.7e-06 F | - | 4.7e-06 F — Capacitance matches. | |
| Esr | 2.9 Ω | 4.0 Ω | 2.0 Ω | 4.0 Ω / 2.0 Ω — ESR is higher than target, may affect circuit performance.; T491C475K035AT: Lower ESR is an improvement. |
Verified drop-in options for 293D475X9016A2TE3 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
