Parameter Comparison

Engineering Selection Recommendations

Both the ALC80D473EL040 and ALC80A473EL040 are Active product status components manufactured by KEMET within the ALC80 series. Both parts maintain ROHS3 Compliant and REACH Unaffected certifications, meeting current regulatory requirements for electronic component deployment.

The ALC80A473EL040 substitute demonstrates equivalent electrical performance with a marginally lower ESR value (16.56 mOhm versus 17 mOhm @ 100Hz), which represents an improvement in power dissipation characteristics. All mechanical dimensions, lead spacing, and mounting configurations are identical, ensuring direct board-level compatibility without PCB redesign.

Selection between these parts is determined by component availability and inventory status. Both parts satisfy the full parameter specification for 47000 µF, 40 V aluminum electrolytic capacitor applications in general purpose circuits.

Frequently Asked Questions (FAQ)

Q: Can the ALC80A473EL040 be used as a direct replacement for the ALC80D473EL040?

A: Yes. The ALC80A473EL040 meets all electrical and mechanical equivalence criteria. Capacitance, voltage rating, tolerance, temperature range, ripple current specifications, and physical dimensions are identical. The substitute part exhibits lower ESR, which is a performance advantage. No circuit modifications or PCB changes are required.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) of 16.56 mOhm in the substitute versus 17 mOhm in the main part represents a 2.6% reduction. Lower ESR results in reduced heat generation during ripple current operation. Both values fall within acceptable operating parameters for this capacitor category.
