ALS70H474NF025 Equivalent & Substitute Parts

Part Overview

The ALS70H474NF025 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 in chassis-mount configurations. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the ALS70H474NF025 are identified based on strict parametric equivalence. The substitution logic is based on the following critical parameters that must remain identical:

Electrical Parameters (Must Match Exactly):

• 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
• Impedance: 10 mOhms

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 1.252" (31.80 mm)
• Diameter: 3.031" (77.00 mm)
• Height - Seated (Max): 4.213" (107.00 mm)
• Mounting Type: Chassis Mount
• Package / Case: Radial, Can - Screw Terminals

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ALS70A474NF025 meets all these criteria and is classified as a parametric equivalent. Both parts belong to the KEMET ALS70 series and share identical electrical performance, physical dimensions, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70H474NF025 and ALS70A474NF025 are active production parts from KEMET with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on availability and inventory status:

ALS70H474NF025: Primary part number with 1007 units in stock. Recommended for immediate procurement when availability is not constrained.

ALS70A474NF025: Parametric equivalent with 749 units in stock. Suitable for use when the primary part number is unavailable or when secondary sourcing is required. No performance or compliance differences exist between the two part numbers.

Both parts maintain the same regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification) and are suitable for direct substitution in applications requiring 470000 µF, 25 V aluminum electrolytic capacitors with screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can ALS70A474NF025 be used as a direct replacement for ALS70H474NF025?

A: Yes. The ALS70A474NF025 is a parametric equivalent with identical electrical performance, mechanical dimensions, and regulatory compliance. Direct substitution is supported without circuit redesign or performance impact.

Q: Are there any differences in the screw terminal specifications between these parts?

A: No. Both parts feature identical radial, can-style screw terminals with 1.252" (31.80 mm) lead spacing. Terminal compatibility is identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ALS70H474NF025 and ALS70A474NF025 are ROHS3 compliant, REACH unaffected, and classified as EAR99. Regulatory compliance is identical.

Q: What is the difference between the ALS70H and ALS70A base product numbers?

A: The base product numbers (ALS70H vs. ALS70A) represent different internal KEMET product designations within the ALS70 series. However, when paired with identical capacitance, voltage, and tolerance values (474NF025), the resulting parts are parametric equivalents with no functional differences.

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

A: Yes. Both parts support 28 A ripple current at 100 Hz and 28.6 A at 10 kHz, making them suitable for applications with moderate to high ripple current requirements.

Q: What is the expected operational lifetime of these capacitors?

A: Both parts are rated for 20000 hours at 85°C operating temperature. Actual lifetime depends on operating conditions, ambient temperature, and ripple current levels.

Q: Are these parts suitable for chassis-mount applications?

A: Yes. Both parts are designed for chassis-mount configurations with screw terminal connections. The 3.031" diameter and 4.213" maximum seated height accommodate standard chassis-mount installations.
