Substitute Part Grouping Explanation

Substitution eligibility for the ALS71U513NF100 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 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)
• Ripple current specifications @ 100Hz and 10kHz (exact match required)

Mechanical Equivalence Criteria:

• Lead spacing: 31.80 mm (exact match required)
• Diameter: 77.00 mm (exact match required)
• Height - Seated (Max): 107.00 mm (exact match required)
• Package type: Radial, Can - Screw Terminals (exact match required)
• Mounting type: Chassis Mount (exact match required)

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Status: REACH Unaffected (required)

The ALS70A513NF100 meets all specified criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71U513NF100 and ALS70A513NF100 are Active product status components 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 part numbers is based on inventory availability and supply chain considerations. Both components satisfy identical electrical performance requirements, mechanical fit specifications, and regulatory compliance mandates. The ALS70A513NF100 currently maintains higher inventory levels (786 Pcs) compared to the ALS71U513NF100 (747 Pcs), which may influence procurement decisions in supply-constrained scenarios.

No technical performance differentiation exists between these components. Direct substitution is permissible in all applications where the ALS71U513NF100 is specified.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A513NF100 be used as a direct replacement for the ALS71U513NF100?

A: Yes. The ALS70A513NF100 is a parametric equivalent substitute. All electrical parameters, mechanical dimensions, and compliance certifications are identical. Direct substitution is permissible without circuit redesign or PCB layout modification.

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

A: The series designation reflects internal KEMET product line classification. Both series share identical electrical specifications, mechanical construction, and performance characteristics for this specific part number configuration. The difference is administrative rather than technical.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both the ALS71U513NF100 and ALS70A513NF100 feature radial can construction with screw terminals. Lead spacing (31.80 mm), terminal configuration, and mounting interface are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) rating. Regulatory and environmental compliance is equivalent.

Q: What is the significance of the 20000-hour lifetime rating at 85°C?

A: This specification indicates the expected operational life under continuous ripple current stress at maximum rated temperature. Both substitute parts maintain identical lifetime performance, ensuring equivalent reliability in thermal stress applications.

Q: Can these parts be used interchangeably in existing designs without testing?

A: Yes. Complete electrical and mechanical equivalence eliminates the requirement for design verification or performance testing when substituting between these part numbers.
