ALS81H822DF100 Equivalent & Substitute Parts

Part Overview

The ALS81H822DF100 is an 8200 µF, 100 V aluminum electrolytic capacitor manufactured by KEMET in the ALS81 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is currently Active in product status with 871 pieces in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the same application requirements.

Substitute Part Grouping Explanation

Substitute parts for the ALS81H822DF100 are identified based on strict equivalence of electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

• Capacitance: 8200 µF (exact match)
• Voltage Rating: 100 V (exact match)
• Tolerance: ±20% (exact match)
• ESR @ 100Hz: 38 mOhm (exact match)
• Lifetime @ 105°C: 6000 Hrs (exact match)
• Operating Temperature Range: -40°C ~ 105°C (exact match)
• Ripple Current @ 100 Hz: 10 A (exact match)
• Ripple Current @ 10 kHz: 13.6 A (exact match)
• Impedance: 31 mOhms (exact match)

Mechanical Equivalence Requirements:

• Package / Case: Radial, Can - Screw Terminals (exact match)
• Lead Spacing: 0.504" (12.80mm) (exact match)
• Diameter: 1.417" (36.00mm) (exact match)
• Height - Seated (Max): 4.213" (107.00mm) (exact match)
• Mounting Type: Chassis Mount (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99

The ALS80A822DF100 meets all electrical and mechanical equivalence criteria and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

The parts differ only in their series designation (ALS81 versus ALS80), while maintaining identical electrical performance, mechanical dimensions, and thermal characteristics.

Selection between these parts should be based on availability and supply chain requirements. Both parts are currently in stock with sufficient inventory. The ALS81H822DF100 has higher current inventory (871 pieces) compared to the ALS80A822DF100 (747 pieces). No technical performance differentiation exists between these parts for general-purpose applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the ALS80A822DF100 be used as a direct replacement for the ALS81H822DF100?

A: Yes. The ALS80A822DF100 is a parametric equivalent substitute. All electrical specifications, mechanical dimensions, lead spacing, and thermal ratings are identical. Both parts are ROHS3 compliant and manufactured by KEMET.

Q: What is the difference between the ALS81 and ALS80 series?

A: The series designation differs between ALS81 and ALS80. However, for the 8200 µF, 100 V specification, all provided electrical and mechanical parameters are identical. The series difference does not affect performance in applications requiring these specifications.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both the ALS81H822DF100 and ALS80A822DF100 use Radial, Can - Screw Terminals with identical lead spacing of 0.504" (12.80mm). PCB layout and mounting procedures are interchangeable.

Q: Do both parts have the same physical dimensions?

A: Yes. Both parts have identical dimensions: 1.417" diameter (36.00mm) and 4.213" maximum seated height (107.00mm). Both are Chassis Mount components with identical footprints.

Q: What is the ESR specification and why is it important?

A: Both parts have an ESR (Equivalent Series Resistance) of 38 mOhm at 100 Hz. ESR affects ripple current handling and thermal performance. Identical ESR values ensure equivalent performance in power supply and filtering applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory and environmental compliance is identical.

Q: What is the ripple current rating and how does it apply?

A: Both parts support 10 A ripple current at 100 Hz and 13.6 A at 10 kHz. These ratings define the maximum AC current the capacitor can handle without exceeding temperature limits. Ratings are identical between both parts.

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

A: Yes. The identical electrical specifications, mechanical dimensions, lead spacing, and mounting type allow direct substitution without design modifications. PCB layouts and circuit designs require no changes.
