Is there a pin-compatible replacement for 10TPE220ML?

Yes, both 10TPE220MIL and 10TPB220ML from Panasonic are pin-compatible replacements in the same D3L package. Note that 10TPE220MIL is an upgrade (lower ESR), while 10TPB220ML has higher ESR and requires review.

What risks should I check before replacing 10TPE220ML?

The main risks are package and electrical mismatches. Ensure the replacement has the same D3L (7.3x4.3x4.0mm) footprint. Critically, verify the ESR is not significantly higher than the original's 25mΩ to avoid performance degradation or overheating.

10TPE220ML Alternatives, Datasheet & Cross Reference | PANASONIC

The Panasonic 10TPE220ML is a 220µF 10V low-ESR polymer tantalum capacitor in a D3L package. When seeking alternatives, focus on matching the 25mΩ ESR, package dimensions, and voltage rating.

Electrical riskmedium

ESR is a critical parameter; higher ESR can cause issues.

Package risklow

Several candidates share the same D3L package, but others have different heights.

Sourcing risklow

Alternatives are available from the same and other manufacturers.

Can it be replaced directly?

Yes, 10TPE220MIL is a direct replacement and potential upgrade. 10TPB220ML is also a direct fit but has higher ESR, requiring review.

Best replacement path

The ideal replacement is 10TPE220MIL, an upgrade from the same Panasonic TPE series with even lower ESR.

Main risk

The primary risk when substituting is accepting a part with higher ESR, which can impact circuit performance and reliability.

Recommended alternatives

A potential upgrade from the same manufacturer and series with lower ESR (18mΩ vs 25mΩ).
