ALS71P474NF025 Equivalent & Substitute Parts

Part Overview

The ALS71P474NF025 is a 470000 µF, 25 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 is currently active in production with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component flexibility within equivalent electrical and mechanical specifications.

• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 9 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Ripple current specifications: 28 A @ 100 Hz and 28.6 A @ 10 kHz (exact match required)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - Screw Terminals (exact match required)
• Lead spacing: 1.252" (31.80 mm) (exact match required)
• Physical dimensions: 3.031" Dia (77.00 mm) and 4.213" height (exact match required)
• Mounting type: Chassis Mount (exact match required)

Compliance Equivalence Criteria:

• RoHS3 Compliant status (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Unaffected status (exact match required)

The ALS70A474NF025 meets all electrical, mechanical, and compliance criteria for direct substitution with the ALS71P474NF025.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P474NF025 and ALS70A474NF025 are active production parts from KEMET with identical electrical performance, mechanical dimensions, and compliance certifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical differentiation.

The ALS71P474NF025 (814 units in stock) and ALS70A474NF025 (749 units in stock) are functionally interchangeable for all applications requiring a 470000 µF, 25 V aluminum electrolytic capacitor with screw terminals and chassis mount configuration. Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications.

The difference between the ALS71 and ALS70 series designations reflects internal KEMET product line organization and does not indicate functional or performance variation for this specific capacitance and voltage rating.
