ALS70P274NT063 Equivalent & Substitute Parts

Part Overview

The ALS70P274NT063 is a 270000 µF aluminum electrolytic capacitor rated at 63 V with screw terminals, manufactured by KEMET in the ALS70 series. This component is classified as an active product and is designed for general-purpose applications requiring high-capacitance energy storage in chassis-mount 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 low and high frequencies.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when design requirements permit functional alternatives within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors in the 270000 µF, 63 V category 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)
• Ripple Current @ 100 Hz: 34.2 A (exact match required)
• Ripple Current @ 10 kHz: 35.5 A (exact match required)

Mechanical Parameters (Non-Negotiable):

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

Compliance Parameters:

• RoHS3 Compliance (required)
• MSL Rating: 1 (Unlimited) (required)

The substitute part ALS70A274NT063 meets all electrical, mechanical, and compliance requirements and is therefore classified as a parametric equivalent within the ALS70 series family.

Parameter Comparison

Engineering Selection Recommendations

Both ALS70P274NT063 and ALS70A274NT063 are active products manufactured by KEMET and maintain full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, ESR, ripple current ratings, thermal lifetime, and physical dimensions.

Selection between these two part numbers may be based on:

• Inventory Availability: ALS70A274NT063 currently has 1162 units in stock compared to 818 units for ALS70P274NT063
• Supply Chain Continuity: Either part number provides equivalent functional performance and can be used interchangeably in circuit designs
• Procurement Lead Time: Availability of either variant should be verified with the supplier for specific delivery requirements

Both parts are suitable for general-purpose applications requiring high-capacitance energy storage with robust screw terminal connections in chassis-mount configurations.

Frequently Asked Questions (FAQ)

Q: Can ALS70A274NT063 be used as a direct replacement for ALS70P274NT063?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (270000 µF, 63 V, ±20% tolerance, 7 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), identical mechanical dimensions (77.00 mm diameter, 222.00 mm height, 31.80 mm lead spacing), and identical package configuration (Radial, Can - Screw Terminals). No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?
