ALS70C474NF025 Equivalent & Substitute Parts

Part Overview

The ALS70C474NF025 is a 470000 µF, 25 V aluminum electrolytic capacitor with screw terminals, manufactured by KEMET in the ALS70 series. This radial, can-mount component is designed for general-purpose applications requiring high capacitance values with extended operational life. The part maintains an active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the ALS70C474NF025 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A474NF025 qualifies as a direct equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 470000 µF
• Identical rated voltage: 25 V
• Identical tolerance: ±20%
• Identical ESR: 9 mOhm @ 100Hz
• Identical lifetime rating: 20000 Hrs @ 85°C
• Identical operating temperature range: -40°C to 85°C
• Identical ripple current specifications at both 100 Hz and 10 kHz
• Identical impedance: 10 mOhms

Mechanical Parameter Equivalence:

• Identical lead spacing: 31.80 mm (1.252")
• Identical physical dimensions: 77.00 mm diameter, 107.00 mm height
• Identical mounting type: Chassis Mount
• Identical package configuration: Radial, Can - Screw Terminals

Compliance Equivalence:

• Both parts maintain ROHS3 compliance
• Both parts are REACH unaffected
• Both parts carry MSL rating of 1 (Unlimited)

The only distinction between the main part and substitute is the base product number series designation (ALS70C versus ALS70A), which reflects internal KEMET product line organization and does not affect functional or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70C474NF025 and ALS70A474NF025 are active products manufactured by KEMET with full regulatory compliance. Selection between these parts should be based on availability and inventory status rather than technical differentiation, as all electrical and mechanical parameters are identical.

The ALS70C474NF025 maintains 686 pieces in current inventory stock. The ALS70A474NF025 maintains 749 pieces in current inventory stock. Both parts carry ROHS3 compliance certification and REACH unaffected status, making either suitable for applications subject to environmental regulations.

For applications requiring this 470000 µF, 25 V aluminum electrolytic capacitor with screw terminals, either part number provides equivalent performance and mechanical fit. Selection may be determined by supplier availability, lead time requirements, or existing component procurement agreements.
