Substitute Part Grouping Explanation

Substitution eligibility for the ALS71C913MF063 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 91000 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100 Hz: 9 mOhm (exact match required)
• Lifetime @ 85°C: 19000 Hours (exact match required)
• Ripple current specifications at both 100 Hz and 10 kHz (exact match required)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - Screw Terminals (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Lead spacing: 1.122" (28.50 mm) (exact match required)
• Physical dimensions: 2.598" diameter × 4.213" height seated (exact match required)

Compliance Equivalence Criteria:

• RoHS3 compliance status (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

The ALS70A913MF063 meets all substitution criteria as a parametric equivalent within the KEMET aluminum electrolytic capacitor product line.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C913MF063 and ALS70A913MF063 are active production parts manufactured by KEMET with full ROHS3 compliance and unlimited moisture sensitivity level ratings. Selection between these parts should be based on the following factors:

Primary Selection Criteria:

• Inventory availability at the time of procurement
• Lead time requirements from supplier
• Cost differential between part numbers
• Existing supply chain relationships with KEMET

Compliance Considerations: Both parts meet identical regulatory requirements including ROHS3 compliance, REACH unaffected status, and EAR99 export classification. No compliance-based differentiation exists between these alternatives.

Operational Equivalence: The ALS70A913MF063 provides complete functional and mechanical interchangeability with the ALS71C913MF063. The difference in series designation (ALS70 versus ALS71) reflects internal KEMET product line organization and does not affect electrical performance, thermal characteristics, or mechanical fit within the application.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A913MF063 be used as a direct replacement for the ALS71C913MF063?

A: Yes. The ALS70A913MF063 is a parametric equivalent with identical electrical specifications, mechanical dimensions, lead spacing, and compliance certifications. Direct substitution is supported without circuit modification or board redesign.

Q: Are there any differences in thermal performance between these two parts?

A: No. Both parts specify 19000 hours lifetime at 85°C operating temperature and identical ripple current ratings at 100 Hz (26.6 A) and 10 kHz (29.3 A). Thermal performance is equivalent.

Q: Do these parts require different mounting procedures?

A: No. Both parts use identical screw terminal connections, chassis mount configuration, and lead spacing of 1.122" (28.50 mm). Mounting procedures and PCB layout remain unchanged.

Q: What is the significance of the different series designations (ALS71 versus ALS70)?

A: Series designation reflects KEMET's internal product line organization. It does not indicate functional differences, performance variations, or compatibility limitations. Both series meet the same electrical and mechanical specifications for this capacitance and voltage rating.

Q: Are both parts currently available for procurement?

A: Both parts are in active production status. Current inventory shows 848 units of ALS71C913MF063 and 828 units of ALS70A913MF063 available. Availability may vary by distributor and time of inquiry.

Q: Do these capacitors require any special handling or storage conditions?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply. Refer to KEMET technical documentation for detailed handling and storage guidelines.

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

A: Yes. Both parts are rated for 26.6 A ripple current at 100 Hz and 29.3 A at 10 kHz. Ripple current specifications are identical, supporting equivalent performance in high-current applications.
