Parameter Comparison

Engineering Selection Recommendations

Both the ALS71U623NP100 and ALS70A623NP100 are active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on:

Inventory Availability: The ALS71U623NP100 maintains 1078 units in stock, while the ALS70A623NP100 maintains 1026 units. Both quantities support standard procurement cycles.

Series Designation: The ALS71U623NP100 belongs to the ALS71 series, while the ALS70A623NP100 belongs to the ALS70 series. Series designation reflects internal KEMET product line organization and does not affect electrical or mechanical performance for this application.

Compliance Certifications: Both parts carry identical compliance certifications (ROHS3, REACH unaffected, MSL 1) and are suitable for applications requiring regulatory compliance documentation.

Direct Substitution: The ALS70A623NP100 functions as a direct parametric equivalent and may be substituted without circuit redesign or performance degradation when the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A623NP100 be used as a direct replacement for the ALS71U623NP100?

A: Yes. The ALS70A623NP100 is a parametric equivalent with identical electrical specifications (62000 µF, 100 V, 11 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), mechanical dimensions (3.031" Dia, 5.827" height, 1.252" lead spacing), and compliance certifications. Direct substitution is supported without circuit modification.

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

A: No. Both parts feature identical radial, can-style screw terminal packages with matching lead spacing of 1.252" (31.80mm) and chassis mount configuration.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the ALS71U623NP100 and ALS70A623NP100 are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). They are suitable for identical regulatory environments.

Q: What is the difference between the ALS71 and ALS70 series designations?

A: Series designation reflects KEMET's internal product line organization. For the 62000 µF, 100 V specification, both series provide identical electrical performance, ripple current ratings (28.9 A @ 100 Hz, 31.2 A @ 10 kHz), and operating temperature range (-40°C ~ 85°C).

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

A: Yes. Identical mechanical dimensions, lead spacing, and mounting type (chassis mount) ensure direct compatibility with existing board layouts and mechanical assemblies.

Q: What is the tolerance specification for capacitance?

A: Both parts carry ±20% capacitance tolerance, meaning the actual capacitance value will fall within the range of 49600 µF to 74400 µF at rated conditions.

Q: Are there any differences in ripple current handling between these parts?

A: No. Both parts are rated for identical ripple current specifications: 28.9 A @ 100 Hz and 31.2 A @ 10 kHz.
