Substitute Part Grouping Explanation

Substitution of the ALS71A752NF400 is based on strict equivalence of the following critical parameters:

Electrical Parameters (Must Match):

• 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):

• 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 & Certifications (Must Match):

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

The ALS70A752NF400 qualifies as a parametric equivalent because it maintains identical electrical performance and mechanical compatibility across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71A752NF400 and ALS70A752NF400 are Active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically interchangeable across all specified parameters. Selection between these parts should be based on:

1. Inventory Availability: The ALS71A752NF400 has 1019 units in stock, while the ALS70A752NF400 has 912 units in stock.

2. Series Designation: The parts differ only in series designation (ALS71 versus ALS70), which reflects internal KEMET product line organization and does not affect electrical or mechanical performance.

3. Compliance Requirements: Both parts meet identical regulatory requirements (ROHS3 Compliant, REACH Unaffected, MSL 1).

4. Application Compatibility: Both parts are suitable for general-purpose applications requiring 7500 µF capacitance at 400 V with identical thermal and electrical performance characteristics.
