Substitute Part Grouping Explanation

Substitution of the ALS70P752NF400 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A752NF400 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance: 7500 µF
• Voltage Rating: 400 V
• Tolerance: ±20%
• ESR @ 100Hz: 29 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 16.4 A
• Ripple Current @ 10 kHz: 23 A

Mechanical Parameters (Must Match Exactly):

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

Compliance & Status:

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Manufacturer: KEMET

The substitute part differs only in the base product number designation (ALS70A versus ALS70P), indicating a variant within the same product series that maintains full parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70P752NF400 and ALS70A752NF400 are Active products manufactured by KEMET and maintain identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

ALS70P752NF400 is the primary part number with 1013 units in stock.

ALS70A752NF400 is the parametric equivalent with 912 units in stock and serves as a direct substitute when the primary part number is unavailable.

Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, making them suitable for applications requiring regulatory compliance. The Moisture Sensitivity Level of 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.

Selection should be based on procurement lead time, inventory availability, and supply chain requirements. No technical re-qualification is necessary when substituting between these part numbers, as all electrical performance characteristics, thermal ratings, and mechanical dimensions are identical.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NF400 be used as a direct replacement for ALS70P752NF400?

A: Yes. The ALS70A752NF400 is a parametric equivalent with identical electrical specifications (7500 µF, 400 V, 29 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), mechanical dimensions (3.031" Dia × 4.213" Height), and package configuration (Radial, Can - Screw Terminals). No circuit modifications or re-qualification are required.

Q: What is the difference between ALS70P and ALS70A base product numbers?

A: The base product number designation (P versus A) indicates a variant within the ALS70 series. Both variants maintain identical performance parameters and are manufactured by KEMET. The difference is a product line or manufacturing variant designation only.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions: 3.031" diameter (77.00mm), 4.213" maximum seated height (107.00mm), and 1.252" lead spacing (31.80mm). Both use screw terminals and are configured for chassis mount installation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS70P752NF400 and ALS70A752NF400 are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). No additional compliance considerations apply when substituting between these parts.

Q: What is the ripple current rating for these capacitors?

A: The ripple current ratings are 16.4 A @ 100 Hz (low frequency) and 23 A @ 10 kHz (high frequency). These ratings are identical for both part numbers.

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

A: These capacitors are rated for operation from -40°C to 85°C with a lifetime of 20000 hours at 85°C. Applications requiring operation above 85°C require alternative component selection.
