ALS71C752NF400 Equivalent & Substitute Parts

Part Overview

The ALS71C752NF400 is a 7500 µF, 400 V aluminum electrolytic capacitor manufactured by KEMET, designed for general-purpose applications requiring high capacitance and voltage ratings. This radial, can-style capacitor features screw terminals for chassis mount installation and is rated for 20,000 hours of operation at 85°C. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. 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 ALS71C752NF400 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following parameters that must remain constant across all equivalent components:

Critical Electrical Parameters:

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

Critical Mechanical Parameters:

• Lead Spacing: 31.80 mm (exact match required)
• Diameter: 77.00 mm (exact match required)
• Height - Seated (Max): 107.00 mm (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The ALS70A752NF400 qualifies as a parametric equivalent substitute because it maintains identical values across all electrical and mechanical parameters listed above, differing only in the series designation (ALS70 versus ALS71) and base product number, which do not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C752NF400 and ALS70A752NF400 are Active status products manufactured by KEMET with full ROHS3 compliance and REACH unaffected designation. The parts are electrically and mechanically interchangeable based on all provided specifications. Selection between these two part numbers should be based on inventory availability and lead time requirements, as both components satisfy identical functional and compliance requirements for general-purpose aluminum electrolytic capacitor applications requiring 7500 µF capacitance at 400 V rated voltage with screw terminal connections.
