Substitute Part Grouping Explanation

Substitution of the ALS71G134NF063 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 130000 µF (exact match)
• Voltage rating: 63 V (exact match)
• Tolerance: ±20% (exact match)
• ESR @ 100 Hz: 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)
• Physical dimensions: 3.031" Dia (77.00 mm), Height 4.213" (107.00 mm) (exact match)
• Lead spacing: 1.252" (31.80 mm) (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 as a parametric equivalent within the KEMET aluminum electrolytic capacitor product line.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71G134NF063 and ALS70A134NF063 are active production parts 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 two parts should be based on inventory availability and lead time requirements. The ALS71G134NF063 currently has 1061 units in stock, while the ALS70A134NF063 has 1017 units available. Both parts meet all regulatory and environmental compliance requirements for general-purpose aluminum electrolytic capacitor applications. The difference between the ALS71 and ALS70 series designations reflects internal KEMET product line categorization and does not affect functional equivalence for the specified electrical and mechanical requirements.
