Substitute Part Grouping Explanation

Substitute parts for the ALA7DC511DF500 are identified based on strict electrical and mechanical parameter matching within the KEMET ALA7D series. The substitution logic is based on the following criteria:

Critical Matching Parameters:

• 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)
• Operating temperature range: -40°C to 85°C (exact match required)
• Polarization: Polar (exact match required)
• Compliance: AEC-Q200, ROHS3, REACH Unaffected (exact match required)

Allowable Parameter Variations:

• ESR (Equivalent Series Resistance): Variation permitted within component manufacturing tolerances
• Ripple current ratings: Variation permitted; substitute must meet or exceed application requirements
• Impedance: Variation permitted; substitute must meet or exceed application requirements
• Lifetime @ 85°C: Variation permitted; substitute must meet or exceed application requirements

The ALA7DA511DF500 qualifies as a parametric equivalent based on matching all critical parameters while demonstrating improved electrical performance characteristics in ripple current and impedance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ALA7DC511DF500 and ALA7DA511DF500 are active production parts manufactured by KEMET and comply with AEC-Q200 automotive standards and ROHS3 environmental requirements. Selection between these parts is based on the following engineering criteria:

ALA7DC511DF500 Selection:

• Applications requiring the specified ESR and impedance characteristics
• Designs validated against the 1.64 A @ 100 Hz and 4.62 A @ 10 kHz ripple current ratings
• Existing inventory availability of 697 pieces

ALA7DA511DF500 Selection:

• Applications with higher ripple current requirements (2.58 A @ 100 Hz, 5.52 A @ 10 kHz)
• Designs benefiting from lower impedance (175 mOhms vs. 331 mOhms)
• Higher inventory availability of 1095 pieces
• Improved thermal performance characteristics in high-ripple-current environments

Both parts maintain identical electrical specifications for capacitance, voltage rating, tolerance, ESR nominal value, lifetime, and operating temperature range. Physical dimensions and mounting characteristics are identical, ensuring direct mechanical compatibility in through-hole PCB applications.
