Substitute Part Grouping Explanation

Substitution of the ALS71G164NP063 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A164NP063 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 160000 µF
• Identical rated voltage: 63 V
• Identical tolerance: ±20%
• Identical ESR: 8 mOhm @ 100Hz
• Identical lifetime rating: 20000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical ripple current specifications at both 100 Hz and 10 kHz
• Identical impedance: 9 mOhms

Mechanical Parameter Equivalence:

• Identical package type: Radial, Can - Screw Terminals
• Identical mounting type: Chassis Mount
• Identical lead spacing: 1.252" (31.80mm)
• Identical physical dimensions: 3.031" Dia × 5.827" Height (Max)

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts have MSL Rating 1 (Unlimited)
• Both parts are REACH Unaffected
• Both parts carry ECCN EAR99 classification

The only difference between the main part and substitute is the series designation (ALS71 versus ALS70) and base product number, reflecting different manufacturing series within KEMET's product line while maintaining complete functional and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71G164NP063 and ALS70A164NP063 are suitable for direct substitution in applications requiring 160000 µF, 63 V aluminum electrolytic capacitors with screw terminal connections. Selection between these parts should be based on the following factors:

Product Status and Availability: Both parts maintain active production status with KEMET, ensuring long-term supply chain stability and technical support availability.

Regulatory Compliance: Both parts satisfy ROHS3 compliance requirements and are REACH unaffected, making them suitable for applications subject to environmental regulations in the European Union and equivalent jurisdictions.

Certification and Classification: Both parts carry identical ECCN EAR99 classification and HTSUS code 8532.22.0085, ensuring equivalent export control and tariff treatment.

Moisture Sensitivity: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly processes.

Inventory Considerations: The ALS70A164NP063 currently maintains higher inventory levels (1182 units) compared to the ALS71G164NP063 (804 units), which may influence procurement decisions based on lead time requirements.
