ALS71A622NF450 Equivalent & Substitute Parts

Part Overview

The ALS71A622NF450 is a 6200 µF, 450 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 and voltage ratings. The part maintains an active product status with 925 units currently in stock. Substitute parts are identified to support procurement continuity, inventory management, and design flexibility when the primary part becomes unavailable or when alternative series options are required.

Substitute Part Grouping Explanation

Substitution of the ALS71A622NF450 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 6200 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 37 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: 15.6 A (exact match required)
• Ripple Current @ 10 kHz: 22.2 A (exact match required)

Mechanical Parameters (Non-Negotiable):

• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Lead Spacing: 1.252" (31.80 mm) (exact match required)
• Size / Dimension: 3.031" Dia (77.00 mm) (exact match required)
• Height - Seated (Max): 4.213" (107.00 mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The ALS70A622NF450 qualifies as a parametric equivalent because it matches all electrical and mechanical specifications while maintaining identical compliance certifications. The primary distinction is the series designation (ALS70 versus ALS71), which reflects internal design evolution within KEMET's product line while preserving functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71A622NF450 and ALS70A622NF450 are active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and procurement requirements rather than technical performance differences.

Primary Selection Criteria:

1. Inventory Availability: The ALS71A622NF450 has 925 units in stock, while the ALS70A622NF450 has 934 units in stock. Both maintain adequate inventory levels for standard procurement cycles.

2. Series Continuity: If the design documentation specifies the ALS71 series, use ALS71A622NF450. If series flexibility is permitted, either part is functionally equivalent.

3. Compliance Requirements: Both parts satisfy ROHS3 compliance and REACH requirements. No compliance-based differentiation exists.

4. Regulatory and Certification Status: Both parts carry identical ECCN (EAR99) and HTSUS (8532.22.0085) classifications, supporting equivalent regulatory treatment.

Selection of the substitute part is appropriate when the primary part experiences supply constraints, extended lead times, or when procurement strategy favors inventory diversification across equivalent series within the same manufacturer.

Frequently Asked Questions (FAQ)

Q: Can ALS70A622NF450 be used as a direct replacement for ALS71A622NF450 in existing designs?

A: Yes. The ALS70A622NF450 is a parametric equivalent with identical electrical performance, mechanical dimensions, and compliance certifications. Direct substitution is supported without circuit redesign or board layout modification.

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

A: The series designation reflects internal design evolution within KEMET's aluminum electrolytic capacitor product line. Both series deliver identical performance across all specified electrical and mechanical parameters for this 6200 µF, 450 V rating.

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

A: Yes. Both parts use identical radial, can-style screw terminals with 1.252" (31.80 mm) lead spacing. Terminal compatibility is confirmed.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts share identical dimensions: 3.031" diameter (77.00 mm) and 4.213" maximum seated height (107.00 mm). PCB layout and chassis mounting requirements are identical.

Q: What is the ripple current handling capability?

A: Both parts handle 15.6 A at 100 Hz and 22.2 A at 10 kHz. Ripple current specifications are identical across the frequency range.

Q: Are there any temperature-related performance differences?

A: No. Both parts operate across -40°C to 85°C with 20000-hour lifetime at 85°C. Thermal performance is 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, supplier preference, or procurement lead time. Both parts carry active product status.

Q: Is there a cost difference between these parts?

A: Cost information is not provided in the technical specifications. Consult with KEMET or authorized distributors for pricing details.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since both parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same assembly or production batch.

Q: What compliance certifications apply to both parts?
