Parameter Comparison

Engineering Selection Recommendations

Both the ALS80H162KF500 and ALS80A162KF500 are active products manufactured by KEMET with identical electrical performance and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical differentiation.

Primary Selection Criteria:

The ALS80H162KF500 serves as the primary part number with 665 units in stock. This part maintains full compliance with RoHS3 and REACH requirements and is suitable for immediate deployment in applications requiring 1600 µF, 500 V aluminum electrolytic capacitors with screw terminal connections.

Substitute Selection Criteria:

The ALS80A162KF500 is a direct parametric equivalent with 1025 units in stock. This substitute part is selected when the primary part number is unavailable or when higher inventory availability is required. The substitute maintains identical electrical characteristics, mechanical dimensions, and regulatory compliance status.

Both parts are classified as general-purpose components and are suitable for the same circuit applications without modification to board layout, schematic design, or thermal management considerations.

Frequently Asked Questions (FAQ)

Q: Can ALS80A162KF500 be used as a direct replacement for ALS80H162KF500?

A: Yes. The ALS80A162KF500 is a parametric equivalent with identical capacitance (1600 µF), voltage rating (500 V), ESR (142 mOhm @ 100Hz), ripple current ratings, operating temperature range, and physical dimensions. Both parts are manufactured by KEMET in the ALS80 series and are interchangeable at the circuit level.

Q: Are there any differences in the screw terminal specifications between these parts?

A: No. Both parts feature identical radial, can-style screw terminals with a lead spacing of 0.874" (22.20mm). The terminal specifications, mounting type (chassis mount), and mechanical interface are identical.

Q: What is the significance of the base product number difference (ALS80H versus ALS80A)?

A: The base product number designates a variant within the ALS80 series. Both variants maintain identical electrical and mechanical specifications for the 1600 µF, 500 V configuration. The difference does not affect performance, compatibility, or application suitability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS80H162KF500 and ALS80A162KF500 are RoHS3 compliant and REACH unaffected. Both parts carry active product status and are suitable for applications requiring regulatory compliance in these areas.

Q: What is the maximum ripple current these capacitors can handle?

A: The maximum ripple current is 12.8 A at 10 kHz. At lower frequencies (100 Hz), the ripple current rating is 6.8 A. Both parts have identical ripple current specifications.

Q: Are these capacitors suitable for high-temperature applications?

A: These capacitors are rated for operation up to 105°C with a lifetime of 7000 hours at this temperature. The operating temperature range is -40°C to 105°C. Both parts have identical thermal specifications.

Q: What is the ESR (Equivalent Series Resistance) of these capacitors?

A: The ESR is 142 mOhm measured at 100 Hz. This specification is identical for both the ALS80H162KF500 and ALS80A162KF500.

Q: Can these capacitors be used in applications requiring lower voltage ratings?

A: These capacitors are rated for 500 V. They can be used in applications with lower voltage requirements, as the voltage rating represents the maximum safe operating voltage. The 500 V rating provides margin for applications operating at lower voltages.

Q: What is the physical footprint of these capacitors?

A: The diameter is 2.008" (51.00mm) and the maximum seated height is 4.213" (107.00mm). The lead spacing is 0.874" (22.20mm). These dimensions are identical for both part numbers and must be verified against available board space before component selection.
