ALS70G474NF025 Equivalent & Substitute Parts

Part Overview

The ALS70G474NF025 is a 470000 µF, 25 V aluminum electrolytic capacitor manufactured by KEMET in the ALS70 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance values with extended operational lifetime. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. 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.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70G474NF025 and ALS70A474NF025 are active production parts manufactured by KEMET with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on the following factors:

Inventory Availability: The ALS70G474NF025 currently has 876 pieces in stock, while the ALS70A474NF025 has 749 pieces available. Component selection should prioritize inventory status based on project delivery requirements.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for applications with regulatory compliance requirements. Both parts carry EAR99 export classification and identical HTSUS codes (8532.22.0085).

Moisture Sensitivity: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Series Consistency: Both parts belong to the KEMET ALS70 series, ensuring design continuity within component families.

Functional Equivalence: The identical electrical parameters (capacitance, voltage, ESR, ripple current, impedance, and lifetime) and mechanical dimensions (lead spacing, diameter, height) ensure direct functional substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can ALS70A474NF025 be used as a direct replacement for ALS70G474NF025?

A: Yes. The ALS70A474NF025 is a parametric equivalent with identical electrical specifications (470000 µF, 25 V, 9 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), mechanical dimensions (77.00 mm diameter, 107.00 mm height, 31.80 mm lead spacing), and compliance certifications (ROHS3, MSL 1). No circuit modifications or board layout changes are required.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by exact matching of: capacitance (470000 µF), voltage rating (25 V), tolerance (±20%), ESR @ 100Hz (9 mOhm), lifetime @ 85°C (20000 Hrs), operating temperature range (-40°C ~ 85°C), ripple current @ 100 Hz (28 A), ripple current @ 10 kHz (28.6 A), and impedance (10 mOhms).

Q: Are the mechanical dimensions identical between the main part and substitute?

A: Yes. Both parts have identical lead spacing (31.80 mm), diameter (77.00 mm), and maximum seated height (107.00 mm). Both use chassis mount configuration with radial, can-style screw terminals, ensuring identical PCB footprint and mounting requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS70G474NF025 and ALS70A474NF025 are ROHS3 compliant, REACH unaffected, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical EAR99 export classification and HTSUS code (8532.22.0085).

Q: What is the difference between the ALS70G and ALS70A base product numbers?

A: The base product numbers (ALS70G versus ALS70A) represent different internal KEMET product designations within the ALS70 series. However, the complete part numbers ALS70G474NF025 and ALS70A474NF025 specify identical electrical and mechanical parameters, making them functionally equivalent for engineering applications.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Yes. Both parts are rated for 28 A ripple current @ 100 Hz and 28.6 A @ 10 kHz, with identical 9 mOhm ESR @ 100Hz. The electrical performance in high-ripple-current applications is identical between the two part numbers.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Packaging format differences, if any, do not affect electrical or mechanical performance.
