ALS71P274NT063 Equivalent & Substitute Parts

Part Overview

The ALS71P274NT063 is a 270000 µF aluminum electrolytic capacitor rated at 63 V with screw terminals, manufactured by KEMET in the ALS71 series. This component is classified as an active product and is designed for general-purpose applications requiring high-capacitance energy storage in chassis-mounted configurations. The part features a radial can design with screw terminal connections, making it suitable for applications demanding robust mechanical attachment and high ripple current handling at both low and high frequencies.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate component availability variations across manufacturing batches and inventory cycles.

Substitute Part Grouping Explanation

Substitution of the ALS71P274NT063 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 270000 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 7 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Ripple Current @ 100 Hz: 34.2 A (exact match required)
• Ripple Current @ 10 kHz: 35.5 A (exact match required)

Mechanical Parameters (Non-Negotiable):

• Lead Spacing: 31.80 mm (exact match required)
• Diameter: 77.00 mm (exact match required)
• Height - Seated (Max): 222.00 mm (exact match required)
• Package Type: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The ALS70A274NT063 qualifies as a parametric equivalent substitute because it maintains identical electrical performance, mechanical dimensions, and compliance certifications across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P274NT063 and ALS70A274NT063 are active products manufactured by KEMET with full ROHS3 compliance and identical electrical and mechanical specifications. The distinction between these parts lies in their series designation (ALS71 versus ALS70), which reflects different manufacturing generations or product line iterations within KEMET's aluminum electrolytic capacitor portfolio.

Selection between these two parts should be based on:

1. Inventory Availability: The ALS70A274NT063 currently maintains 1162 pieces in stock, while the ALS71P274NT063 maintains 1122 pieces in stock. Either part is suitable for immediate procurement.

2. Supply Chain Continuity: Both parts carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification, HTSUS 8532.22.0085). Either part can be substituted without affecting regulatory or export documentation requirements.

3. Mechanical Compatibility: Identical lead spacing (31.80 mm), diameter (77.00 mm), and height (222.00 mm) ensure direct mechanical interchangeability in chassis-mounted applications without PCB redesign or mechanical rework.

4. Electrical Performance: Identical capacitance, voltage rating, ESR, ripple current ratings, and lifetime specifications ensure functional equivalence in all general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A274NT063 be used as a direct replacement for the ALS71P274NT063?

A: Yes. The ALS70A274NT063 is a parametric equivalent with identical electrical specifications (270000 µF, 63 V, ±20% tolerance, 7 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), mechanical dimensions (77.00 mm diameter, 222.00 mm height, 31.80 mm lead spacing), and compliance certifications (ROHS3 Compliant, MSL 1). Direct substitution is supported without circuit or mechanical modifications.

Q: Are there any differences in performance between the ALS71P274NT063 and ALS70A274NT063?

A: No performance differences exist. Both parts deliver identical ripple current handling (34.2 A @ 100 Hz, 35.5 A @ 10 kHz), impedance (8 mOhms), operating temperature range (-40°C to 85°C), and lifetime rating (20000 Hrs @ 85°C). The series designation difference (ALS71 versus ALS70) reflects manufacturing lineage, not functional variation.

Q: Will substituting the ALS70A274NT063 require PCB layout changes?

A: No. Both parts feature identical lead spacing (31.80 mm), package type (Radial, Can - Screw Terminals), and mounting configuration (Chassis Mount). PCB footprints and mechanical mounting hardware remain unchanged.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the ALS71P274NT063 and ALS70A274NT063 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export purposes. Both carry identical HTSUS classification (8532.22.0085). Regulatory documentation and certifications are interchangeable.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. Both parts carry Active product status and are supported by KEMET for ongoing production and supply.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. Identical electrical performance, mechanical dimensions, and compliance certifications support full interchangeability in existing assemblies without functional, mechanical, or regulatory impact.
