Substitute Part Grouping Explanation

Substitution of the ALS71H363MF100 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A363MF100 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 36000 µF
• Identical voltage rating: 100 V
• Identical tolerance: ±20%
• Identical ESR: 14 mOhm @ 100Hz
• Identical lifetime rating: 19000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical ripple current specifications at both 100 Hz and 10 kHz
• Identical impedance: 12 mOhms

Mechanical Parameter Equivalence:

• Identical lead spacing: 28.50 mm
• Identical diameter: 66.00 mm
• Identical seated height: 107.00 mm
• Identical mounting type: Chassis Mount
• Identical package configuration: Radial, Can - Screw Terminals

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected

The only difference between the main part and substitute is the series designation (ALS71 versus ALS70) and base product number, which reflects internal KEMET product line organization without affecting functional or physical compatibility.
