Substitute Part Grouping Explanation

Substitution eligibility for the ALS70H752NJ400 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A752NJ400 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 7500 µF
• Identical rated voltage: 400 V
• Identical tolerance: ±20%
• Identical ESR @ 100Hz: 29 mOhm
• Identical lifetime rating: 20000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical ripple current specifications at both 100 Hz (16.7 A) and 10 kHz (23.7 A)
• Identical impedance: 19 mOhms

Mechanical Parameter Equivalence:

• Identical package type: Radial, Can - Screw Terminals
• Identical mounting type: Chassis Mount
• Identical physical dimensions: 3.031" Dia (77.00mm), Height 4.606" (117.00mm)
• Identical lead spacing: 1.252" (31.80mm)

Compliance Equivalence:

• Both parts maintain RoHS3 compliance
• Both parts are REACH unaffected
• Both parts feature MSL Level 1 (Unlimited)

The substitute part differs only in the base product number designation (ALS70A versus ALS70H), which reflects internal KEMET series classification but does not affect functional or physical compatibility.
