Substitute Part Grouping Explanation

Substitute parts are identified based on strict parametric equivalence within the KEMET ALA7D series. The substitution logic is based on the following critical parameters that determine functional interchangeability:

Primary Equivalence Criteria:

• Capacitance value: 510 µF (exact match required)
• Voltage rating: 500 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: 1.378" Dia × 2.047" Height (exact match required)
• Polarization: Polar (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)
• Lifetime rating: 15000 Hrs @ 85°C (exact match required)
• AEC-Q200 automotive rating (exact match required)

Secondary Tolerance Parameters:

• ESR @ 100Hz: 489.8 mOhm (within acceptable engineering tolerance)
• Ripple current specifications (minor variations acceptable within design margins)
• Impedance values (minor variations acceptable within design margins)

The ALA7DA511DF500 meets all primary equivalence criteria and is classified as a parametric equivalent substitute.
