Is there a pin-compatible replacement for PXTD010M227E040STU?

The TORCH CA45-D-10V-220uF-K shares the same D-case package, but has a much higher ESR (200mΩ vs 40mΩ), making it a high-risk downgrade.

What risks should I check before replacing PXTD010M227E040STU?

Key risks include package dimension mismatches (especially height), and significant differences in ESR, which can affect filtering and power delivery performance.

AI replacement insight

Package riskmedium

Several candidates have different case heights, requiring layout verification.

Electrical riskhigh

One form-fit candidate has significantly higher ESR, posing a performance risk.

Sourcing risklow

Multiple vendors offer capacitors with similar core specifications.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. The closest options have different package dimensions or electrical parameters like ESR.

Best replacement path

Consider Panasonic's 10TPE220ML for lower ESR, but verify its smaller package height (D3L case) is compatible with your board layout.

Main risk

The primary risks are mechanical incompatibility due to package differences and performance degradation from higher ESR in some alternatives.

Recommended alternatives

A functional alternative with matching electricals but different package height. Verify board clearance before use.
