ALS71G752NF400 Equivalent & Substitute Parts

Part Overview

The ALS71G752NF400 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 when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the same performance envelope.

Substitute Part Grouping Explanation

Substitute parts for the ALS71G752NF400 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

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 & Status (Must Match):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The ALS70A752NF400 meets all substitution criteria and is classified as a parametric equivalent within the KEMET aluminum electrolytic capacitor portfolio.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71G752NF400 and ALS70A752NF400 are Active products manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory levels rather than electrical or mechanical performance differences. The ALS71G752NF400 currently maintains 965 pieces in stock, while the ALS70A752NF400 maintains 912 pieces in stock. Both parts are suitable for direct substitution in applications requiring 7500 µF capacitance at 400 V with screw terminal connections and chassis mount installation. The difference between the ALS71 and ALS70 series designations reflects internal KEMET product line organization and does not indicate functional or performance variation for this specific capacitance and voltage rating.
