ALS71A513KF063 Equivalent & Substitute Parts

Part Overview

The ALS71A513KF063 is a 51000 µF, 63 V aluminum electrolytic capacitor manufactured by KEMET in the ALS71 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance values in chassis-mount configurations. The part maintains an active product status with 1042 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component flexibility within equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the ALS71A513KF063 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 51000 µF (exact match required)
• Voltage rating: 63 V (minimum acceptable)
• Tolerance: ±20% (matching specification)
• ESR: 14 mOhm @ 100Hz (matching specification)
• Lifetime: 18000 Hours @ 85°C (matching specification)
• Ripple current ratings: 19.1 A @ 100Hz and 21.5 A @ 10kHz (matching specifications)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - Screw Terminals (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Physical dimensions: 2.008" Dia × 4.213" Height (exact match required)
• Lead spacing: 0.874" (22.20mm) (exact match required)

Compliance Equivalence Criteria:

• RoHS3 Compliance (matching status)
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ALS70A513KF063 qualifies as a parametric equivalent substitute because it maintains identical electrical performance, mechanical form factor, and compliance certifications across all specified parameters.

Engineering Selection Recommendations

Primary Part Selection: The ALS71A513KF063 remains the primary specification when available. Both the main part and substitute maintain active product status with KEMET, ensuring continued manufacturer support and supply chain stability.

Substitute Part Selection: The ALS70A513KF063 is a direct parametric equivalent suitable for use when ALS71A513KF063 availability is constrained. The substitute differs only in series designation (ALS70 versus ALS71) while maintaining identical electrical performance, mechanical compatibility, and compliance certifications. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Inventory Considerations: Current inventory levels show 1050 units of ALS70A513KF063 available against 1042 units of ALS71A513KF063, providing equivalent sourcing flexibility for both parts.

Frequently Asked Questions (FAQ)

Q: Can ALS70A513KF063 be used as a direct replacement for ALS71A513KF063?

A: Yes. The ALS70A513KF063 is a parametric equivalent with identical capacitance (51000 µF), voltage rating (63 V), ESR (14 mOhm @ 100Hz), lifetime (18000 Hrs @ 85°C), ripple current ratings, physical dimensions, and screw terminal configuration. Both parts are ROHS3 compliant and suitable for identical circuit applications.

Q: Are there any mechanical compatibility differences between these parts?

A: No. Both parts share identical mechanical specifications: 2.008" diameter, 4.213" height, 0.874" lead spacing, radial can package with screw terminals, and chassis mount configuration. Direct mechanical substitution is supported without PCB or mounting modifications.

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

A: The series designation difference does not affect electrical or mechanical performance for these specific part numbers. Both series are manufactured by KEMET and maintain identical specifications for capacitance, voltage, ESR, lifetime, and physical form factor.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS71A513KF063 and ALS70A513KF063 are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Compliance certifications are identical.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection may be based on current inventory availability or preferred supplier stock levels. Both parts maintain active product status with equivalent lead times and support.

Q: Are there temperature or ripple current performance differences?

A: No. Both parts operate across -40°C to 85°C with identical ripple current ratings of 19.1 A @ 100Hz and 21.5 A @ 10kHz. Thermal and electrical performance characteristics are equivalent.
