Substitute Part Grouping Explanation

Substitution of the ALS71G474NF025 is determined by strict equivalence across electrical and mechanical parameters. The substitute part ALS70A474NF025 maintains identical specifications in the following critical areas:

Electrical Parameters (Must Match):

• Capacitance: 470000 µF
• Voltage Rating: 25 V
• Tolerance: ±20%
• ESR @ 100Hz: 9 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 28 A
• Ripple Current @ 10 kHz: 28.6 A
• Impedance: 10 mOhms

Mechanical Parameters (Must Match):

• Lead Spacing: 31.80 mm
• Diameter: 77.00 mm
• Height: 107.00 mm
• Mounting Type: Chassis Mount
• Package Type: Radial, Can - Screw Terminals

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part differs only in series designation (ALS70 vs. ALS71), indicating a different product line within KEMET's aluminum electrolytic capacitor portfolio while maintaining full parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71G474NF025 and ALS70A474NF025 are active products manufactured by KEMET with full compliance to ROHS3 and REACH regulations. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

ALS71G474NF025 is the primary specification with 976 units currently in stock, providing immediate availability for production requirements.

ALS70A474NF025 is the parametric equivalent with 749 units in stock, suitable for use when primary stock is depleted or when supply chain optimization requires component diversification across KEMET's product lines.

Both parts maintain identical electrical performance, mechanical fit, and regulatory compliance. Direct substitution is permissible in all applications where the ALS71G474NF025 is specified, provided that lead spacing, mounting orientation, and screw terminal compatibility are confirmed in the target assembly.

Frequently Asked Questions (FAQ)

Q: Can ALS70A474NF025 be used as a direct replacement for ALS71G474NF025?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including capacitance, voltage rating, ESR, ripple current, physical dimensions, and mounting configuration are identical. The series designation difference (ALS70 vs. ALS71) reflects product line categorization within KEMET's portfolio but does not affect functional interchangeability.

Q: Are there any differences in lead spacing or mounting footprint?

A: No. Both parts have identical lead spacing of 31.80 mm, diameter of 77.00 mm, and seated height of 107.00 mm. Screw terminal configurations are identical, ensuring direct mechanical compatibility in chassis-mount applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS71G474NF025 and ALS70A474NF025 are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity level). Regulatory and environmental compliance is equivalent.

Q: What is the basis for substitution between these two parts?

A: Substitution is based on complete parametric equivalence across electrical specifications (capacitance, voltage, ESR, ripple current, impedance, lifetime), mechanical dimensions (lead spacing, diameter, height), mounting type (chassis mount with screw terminals), and compliance certifications (ROHS3, REACH). No electrical or mechanical derating is required.

Q: Which part should be selected if both are available?

A: Selection should be based on supply chain availability and inventory levels. The ALS71G474NF025 with 976 units in stock provides greater immediate availability. The ALS70A474NF025 with 749 units in stock is suitable as a secondary source or for long-term supply diversification.
