Parameter Comparison

Engineering Selection Recommendations

Both the ALC80D331EB400 and ALC80A331EB400 are Active product status components manufactured by KEMET within the ALC80 series. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

The ALC80A331EB400 demonstrates parametric equivalence across all electrical and mechanical specifications. The ESR variance of 0.2 mOhm (384 mOhm versus 384.2 mOhm) falls within normal manufacturing tolerance ranges for aluminum electrolytic capacitors and does not constitute a functional difference.

Selection between these parts may be based on inventory availability, lead time, or procurement source, as both components are functionally interchangeable for applications requiring 330 µF, 400 V aluminum electrolytic capacitors in snap-in radial can packages.

Frequently Asked Questions (FAQ)

Q: Can ALC80A331EB400 be used as a direct replacement for ALC80D331EB400?

A: Yes. The ALC80A331EB400 is a parametric equivalent with identical electrical ratings (330 µF, 400 V, ±20% tolerance), identical mechanical dimensions (40 mm diameter, 32 mm height, 10 mm lead spacing), and identical package configuration (radial, can snap-in, through-hole mounting). Both parts are ROHS3 compliant and REACH unaffected.

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

A: The ESR difference of 0.2 mOhm (384 mOhm versus 384.2 mOhm) is negligible and falls within standard manufacturing tolerances for aluminum electrolytic capacitors. This variance does not affect circuit performance or component selection criteria.

Q: Are the physical dimensions identical between ALC80D331EB400 and ALC80A331EB400?

A: Yes. Both parts share identical physical dimensions: 40.00 mm diameter, 32.00 mm seated height, and 10.00 mm lead spacing. Both use radial, can snap-in packages with through-hole mounting, ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both ALC80D331EB400 and ALC80A331EB400 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic component manufacturing and deployment.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in capacitance (330 µF), rated voltage (400 V), tolerance (±20%), lifetime rating (9000 Hrs @ 105°C), operating temperature range (-40°C to 105°C), package type (radial, can snap-in), mechanical dimensions (40 mm diameter, 32 mm height, 10 mm lead spacing), and compliance certifications (ROHS3, REACH).

Q: Can these parts be used in high-ripple-current applications?

A: Both parts are rated for 2.07 A ripple current at 100 Hz and 5.16 A ripple current at 10 kHz. Application suitability depends on circuit-specific ripple current requirements and thermal management conditions.
