Is there a pin-compatible replacement for PXTD006M477E035STU?

No direct pin-to-pin, drop-in replacement has been identified in this review. All viable candidates have different package sizes (either larger or smaller) requiring verification of the PCB layout.

What risks should I check before replacing PXTD006M477E035STU?

Key risks to check are: 1) Physical fit, as package sizes differ. 2) Electrical performance, especially if capacitance is lower or technology (e.g., Al-Poly vs. Ta-Poly) is different, which affects ESR and leakage. 3) Voltage rating, ensure it's at least 6.3V.

Finding a replacement for the PXTD006M477E035STU, a 470µF 6.3V D-case polymer tantalum capacitor, requires careful checking of package size, capacitance, and technology. Alternatives exist but involve trade-offs requiring engineering review.

AI replacement insight

Package riskhigh

No candidates match the 7343 D-case package.

Electrical riskmedium

Candidates have different capacitance or technology.

Sourcing risklow

Multiple alternatives exist from major manufacturers.

Can it be replaced directly?

No direct, drop-in replacement is available. All known alternatives require engineering review for package fit and electrical parameter differences.

Best replacement path

Evaluate board space for a larger Al-Poly capacitor or verify if lower capacitance from a smaller Ta-Poly capacitor is acceptable for the application.

Main risk

The primary risk is physical incompatibility due to different package sizes. A secondary risk is electrical mismatch from different capacitance or technology.

Recommended alternatives

A functional alternative with the same capacitance but a much higher voltage rating, in a larger package and different technology.
