Substitute Part Grouping Explanation

Substitute parts for the ALS80H122DF400 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Capacitance Value: 1200 µF (exact match required)
• Voltage Rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 113 mOhm (exact match required)
• Lifetime @ Temperature: 6000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Ripple Current Ratings: 4.7 A @ 100 Hz and 10.6 A @ 10 kHz (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Physical Dimensions: 1.417" Dia (36.00mm), Height 4.213" (107.00mm), Lead Spacing 0.504" (12.80mm) (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
