Engineering Selection Recommendations

Primary Part: ALC80D331DF500

The ALC80D331DF500 is the specified component with Active product status and full regulatory compliance (ROHS3, REACH unaffected). This part is suitable for direct specification in new designs and existing applications.

Substitute Part: ALC80A331DF500

The ALC80A331DF500 is a direct parametric equivalent with identical electrical and mechanical specifications. Both parts are manufactured by KEMET within the ALC80 series and maintain equivalent performance characteristics. The ESR values are functionally equivalent (517 mOhm vs. 516.9 mOhm @ 100Hz), representing negligible variance within engineering tolerances.

Both parts maintain Active product status and full compliance certifications. Selection between these parts is determined by availability, inventory status, and procurement requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ALC80A331DF500 be used as a direct replacement for ALC80D331DF500?

A: Yes. The ALC80A331DF500 is a parametric equivalent with identical capacitance (330 µF), voltage rating (500 V), tolerance (±20%), lifetime (8000 Hrs @ 105°C), and physical dimensions (35.00 mm diameter, 52.00 mm height). Both use identical radial snap-in package configuration with 10.00 mm lead spacing for through-hole mounting.

Q: Are there any electrical performance differences between these parts?

A: ESR values are functionally equivalent. ALC80D331DF500 specifies 517 mOhm @ 100Hz while ALC80A331DF500 specifies 516.9 mOhm @ 100Hz. This 0.1 mOhm variance is within normal manufacturing tolerances and does not affect circuit performance. Ripple current ratings, impedance, and all other electrical parameters are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ALC80D331DF500 and ALC80A331DF500 are ROHS3 compliant and REACH unaffected. Both maintain Active product status with identical environmental and regulatory certifications.

Q: What is the physical compatibility between these parts?

A: Complete physical compatibility is maintained. Both parts feature identical dimensions (35.00 mm diameter, 52.00 mm seated height), lead spacing (10.00 mm), and radial snap-in package configuration. No PCB layout modifications are required for substitution.

Q: Are there any temperature or operating condition differences?

A: No. Both parts operate across the identical temperature range (-40°C to 105°C) with identical lifetime ratings (8000 Hrs @ 105°C). Operating conditions and thermal performance are equivalent.

Q: What determines the choice between these two parts?

A: Selection is based on availability and procurement factors. Both parts are functionally and mechanically equivalent. The choice depends on inventory status, lead time, and supplier availability rather than technical performance requirements.
