Substitute Part Grouping Explanation

Substitute parts for the ALS71A134NF063 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

• Capacitance value: 130000 µF (exact match)
• Voltage rating: 63 V (exact match)
• Tolerance: ±20% (exact match)
• ESR @ 100Hz: 9 mOhm (exact match)
• Lifetime @ 85°C: 20000 Hrs (exact match)
• Operating temperature range: -40°C ~ 85°C (exact match)
• Ripple current specifications: 27.3 A @ 100 Hz and 28.9 A @ 10 kHz (exact match)

Mechanical Equivalence Requirements:

• Package type: Radial, Can - Screw Terminals (exact match)
• Mounting type: Chassis Mount (exact match)
• Lead spacing: 1.252" (31.80mm) (exact match)
• Physical dimensions: 3.031" Dia (77.00mm), Height 4.213" (107.00mm) (exact match)
• Polarization: Polar (exact match)

Compliance Equivalence:

• RoHS3 Compliant status (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)
• REACH Status: REACH Unaffected (exact match)

The ALS70A134NF063 meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71A134NF063 and ALS70A134NF063 are active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on availability and supply chain requirements. The ALS70A134NF063 currently maintains higher inventory levels (1017 units versus 656 units), which may provide supply chain advantages in high-volume procurement scenarios. Both parts are suitable for direct substitution in applications requiring 130000 µF, 63 V aluminum electrolytic capacitors with screw terminal connections and chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A134NF063 be used as a direct replacement for the ALS71A134NF063?

A: Yes. Both parts are manufactured by KEMET and share identical electrical specifications (130000 µF, 63 V, 9 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), identical mechanical dimensions (3.031" diameter, 4.213" height, 1.252" lead spacing), and identical package configuration (Radial, Can - Screw Terminals, Chassis Mount). No circuit modifications or board layout changes are required.

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

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, Moisture Sensitivity Level 1 (Unlimited), and equivalent ECCN and HTSUS classifications.

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

A: The series designation reflects internal KEMET product line organization. Both series share identical electrical and mechanical specifications for this 130000 µF, 63 V capacitor model. The series difference does not affect functional performance or compatibility.

Q: Are the ripple current ratings identical between these parts?

A: Yes. Both parts are rated for 27.3 A ripple current at 100 Hz and 28.9 A ripple current at 10 kHz, with identical impedance of 10 mOhms.

Q: Can these capacitors be used interchangeably in PCB designs?

A: Yes. The identical lead spacing (1.252" / 31.80mm), diameter (3.031" / 77.00mm), and height (4.213" / 107.00mm) ensure mechanical compatibility with existing board layouts and mounting hardware designed for either part number.

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 20000 hours at 85°C.
