Parameter Comparison

Engineering Selection Recommendations

The ALS80A822DF100 is a direct parametric equivalent to the ALS81A822DF100. Both components are manufactured by KEMET, maintain identical electrical specifications, and share the same mechanical footprint and mounting configuration. Both parts carry Active product status and meet ROHS3 and REACH compliance requirements.

Selection between these two parts may be based on inventory availability and lead time considerations. The ALS81A822DF100 currently has 913 units in stock, while the ALS80A822DF100 has 747 units available. The difference between the ALS81 and ALS80 series designations reflects internal KEMET product line organization and does not indicate functional or performance differences for this specific capacitance and voltage rating combination.

Frequently Asked Questions (FAQ)

Q: Can the ALS80A822DF100 be used as a direct replacement for the ALS81A822DF100?

A: Yes. The ALS80A822DF100 is a parametric equivalent with identical electrical and mechanical specifications. All critical parameters including capacitance, voltage rating, ESR, ripple current ratings, physical dimensions, and mounting configuration are equivalent.

Q: What is the difference between the ALS81 and ALS80 series designations?

A: The series designation reflects KEMET's internal product line classification. For the 8200 µF, 100 V specification, both series deliver identical performance characteristics and are functionally interchangeable.

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

A: No. Both the ALS81A822DF100 and ALS80A822DF100 carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected status.

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

A: Substitution is determined by equivalence in capacitance (8200 µF), voltage rating (100 V), tolerance (±20%), ESR (38 mOhm @ 100Hz), lifetime rating (6000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current specifications (10 A @ 100 Hz, 13.6 A @ 10 kHz), and mechanical dimensions (lead spacing 12.80 mm, diameter 36.00 mm, height 107.00 mm).

Q: Can these capacitors be used in applications requiring different ripple current ratings?

A: No. Both parts are rated for 10 A ripple current at 100 Hz and 13.6 A at 10 kHz. Applications requiring different ripple current specifications require alternative component selection.

Q: What is the significance of the 38 mOhm ESR specification?

A: ESR (Equivalent Series Resistance) at 100 Hz is a critical parameter affecting capacitor performance in filtering and energy storage applications. The 38 mOhm specification is identical between both parts and must be maintained for functional equivalence.

Q: Are these parts suitable for high-frequency applications?

A: These capacitors are rated for ripple current at both low frequency (100 Hz) and high frequency (10 kHz). The impedance specification of 31 mOhms applies across the operating frequency range. Application suitability depends on specific circuit requirements beyond the scope of these parametric specifications.
