• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 10.00 mm (exact match required)
• Physical dimensions: 40.00 mm diameter, 82.00 mm height seated (exact match required)
• Operating temperature range: -40°C to 105°C (exact match required)
• Lifetime rating: 9000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)

Allowable Variation Parameters:

• ESR @ 100Hz: Nominal tolerance ±5% from specified value
• Ripple current ratings: Equivalent or superior performance
• Impedance: Equivalent performance acceptable

The ALC80A112EL450 qualifies as a parametric equivalent substitute based on matching all critical parameters while maintaining functional equivalence in ripple current and impedance specifications.

Frequently Asked Questions (FAQ)

Q: Can ALC80A112EL450 be used as a direct replacement for ALC80D112EL450?

A: Yes. The ALC80A112EL450 is a parametric equivalent substitute. All electrical specifications (capacitance, voltage rating, ESR, ripple current, impedance, lifetime) and mechanical specifications (package type, lead spacing, physical dimensions, mounting configuration) are identical. Both parts are KEMET manufactured within the ALC80 series.

Q: What is the difference between ALC80D and ALC80A designations?

A: The base product numbers ALC80D and ALC80A represent different product lines within the KEMET ALC80 series. For the 1100 µF 450 V snap-in configuration, both designations provide identical electrical and mechanical performance. The designation difference does not affect functional compatibility or application suitability.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both ALC80D112EL450 and ALC80A112EL450 share identical physical specifications: 40.00 mm diameter, 82.00 mm seated height, and 10.00 mm lead spacing. PCB layout and mounting hole patterns are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected. No compliance differences exist between the substitute parts.

Q: What is the ESR specification tolerance?

A: The main part specifies 125 mOhm @ 100Hz, while the substitute specifies 125.1 mOhm @ 100Hz. This 0.1 mOhm differential represents equivalent performance within engineering tolerance for general-purpose applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical lead spacing (10.00 mm), package configuration (Radial, Can - Snap-In), and mounting type (Through Hole) ensure direct PCB compatibility. No design modifications are required for substitution.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 105°C with 9000 hours lifetime rating at 105°C continuous operation.
