Frequently Asked Questions (FAQ)

Q: Can the ALS70A332MF500 be used as a direct replacement for the ALS71C332MF500?

A: Yes. The ALS70A332MF500 is a parametric equivalent with identical electrical specifications, mechanical dimensions, and compliance certifications. Direct substitution is supported without circuit modification.

Q: Are there differences in the series designation between ALS71C and ALS70A?

A: The series designation differs (ALS71 versus ALS70), but all electrical and mechanical parameters are identical. The series designation reflects internal KEMET product line organization and does not affect functional equivalence.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by exact matching of capacitance (3300 µF), rated voltage (500 V), tolerance (±20%), ESR (77 mOhm @ 100 Hz), lifetime (19000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), ripple current specifications, physical dimensions, package type (Radial, Can - Screw Terminals), and compliance status (ROHS3 Compliant, REACH Unaffected).

Q: Are the screw terminal connections identical between these parts?

A: Yes. Both parts feature identical radial, can-style screw terminals with 28.50 mm lead spacing and identical mechanical mounting specifications for chassis mount applications.

Q: Do both parts support the same ripple current ratings?

A: Yes. Both parts support identical ripple current specifications: 12.3 A @ 100 Hz and 19.7 A @ 10 kHz.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 85°C with a rated lifetime of 19,000 hours at 85°C.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) and ECCN/HTSUS classifications.
