Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C912MF250 and ALS70A912MF250 are Active product status components manufactured by KEMET and hold ROHS3 compliance certification. The ALS70A912MF250 substitute part demonstrates electrical and mechanical equivalence across all specified parameters. The ESR differential of 1 mOhm (31 mOhm versus 32 mOhm @ 100Hz) remains within acceptable tolerance margins for aluminum electrolytic capacitor applications. Both components maintain identical capacitance, voltage rating, lifetime rating, temperature operating range, ripple current specifications, and physical dimensions. Selection between these parts may be based on inventory availability, lead time, or procurement requirements, as both satisfy the functional and compliance requirements for direct substitution in chassis-mount, general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A912MF250 be used as a direct replacement for the ALS71C912MF250?

A: Yes. The ALS70A912MF250 is a parametric equivalent substitute. Both parts share identical capacitance (9100 µF), voltage rating (250 V), tolerance (±20%), lifetime (19000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), package type (Radial, Can - Screw Terminals), and physical dimensions. The ESR variance of 1 mOhm is within acceptable tolerance for this component category.

Q: Are there any mechanical compatibility concerns when substituting the ALS70A912MF250 for the ALS71C912MF250?

A: No. Both parts are identical in mechanical specifications: 2.598" diameter (66.00mm), 4.213" maximum seated height (107.00mm), 1.122" lead spacing (28.50mm), and chassis-mount configuration. Direct board-level substitution is supported without modification to mounting hardware or PCB layout.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ALS71C912MF250 and ALS70A912MF250 are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). Both are REACH Unaffected and classified under ECCN EAR99.

Q: What is the difference between the ALS71 and ALS70 series designations?

A: The series designation reflects the internal product line classification within KEMET's aluminum electrolytic capacitor portfolio. Both series meet the specified electrical and mechanical parameters for this 9100 µF, 250 V application. The series difference does not affect functional equivalence for substitution purposes.

Q: Are ripple current ratings identical between these parts?

A: Yes. Both parts are rated for 15.8 A @ 100 Hz and 22.7 A @ 10 kHz, ensuring equivalent performance in AC ripple current applications.
