Substitute Part Grouping Explanation

Substitute parts for the ALS71P513NF100 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Critical Matching Parameters:

• Capacitance: 51000 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 12 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Ripple Current @ 100 Hz: 25.7 A (exact match required)
• Ripple Current @ 10 kHz: 27.9 A (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Physical Dimensions: 3.031" Dia (77.00mm), Height 4.213" (107.00mm), Lead Spacing 1.252" (31.80mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The ALS70A513NF100 meets all substitution criteria and is classified as a parametric equivalent. The primary difference is the series designation (ALS70 versus ALS71), which reflects different product lines within KEMET's aluminum electrolytic capacitor portfolio while maintaining identical electrical performance and mechanical specifications.

Engineering Selection Recommendations

Both the ALS71P513NF100 and ALS70A513NF100 are Active products manufactured by KEMET with identical electrical and mechanical specifications. Selection between these parts should be based on:

Availability and Inventory: The ALS71P513NF100 has 1015 pieces in stock, while the ALS70A513NF100 has 786 pieces in stock. Component selection should prioritize availability based on project timeline and procurement requirements.

Compliance and Certifications: Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0085. Both meet identical regulatory and environmental standards, ensuring interchangeability from a compliance perspective.

Series Designation: The ALS71 series (main part) and ALS70 series (substitute) represent different product lines within KEMET's aluminum electrolytic capacitor portfolio. The series designation does not affect electrical performance or mechanical compatibility in this case, as all critical parameters are identical.

Application Compatibility: Both parts are suitable for general purpose applications requiring 51000 µF capacitance at 100 V with chassis-mount screw terminal configuration. No application-specific limitations exist between the two parts.

Frequently Asked Questions (FAQ)
