Frequently Asked Questions (FAQ)

Q: Can ALS80A124NF063 be used as a direct replacement for ALS80U124NF063?

A: Yes. The ALS80A124NF063 meets all electrical and mechanical parameter requirements for direct substitution. Both parts share identical capacitance (120000 µF), voltage rating (63 V), ESR (9 mOhm @ 100Hz), thermal lifetime (9000 Hrs @ 105°C), and physical dimensions (3.031" diameter, 4.213" height, 1.252" lead spacing).

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

A: No. Both ALS80U124NF063 and ALS80A124NF063 carry identical RoHS3 compliance and REACH unaffected status. Both parts are active products from KEMET with no regulatory or certification differences.

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by exact matching of capacitance value, voltage rating, tolerance, ESR, thermal lifetime, operating temperature range, ripple current specifications, lead spacing, physical dimensions, mounting type, and package configuration. All these parameters are identical between the main part and substitute.

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

A: Yes. The identical lead spacing (1.252" / 31.80mm), diameter (3.031" / 77.00mm), and height (4.213" / 107.00mm) ensure mechanical compatibility with existing PCB layouts and chassis mount configurations. No design modifications are required.

Q: What is the difference between the part number designations ALS80U and ALS80A?

A: The designations ALS80U and ALS80A represent different internal product variants within the KEMET ALS80 series. Despite this nomenclature difference, both variants meet identical electrical and mechanical specifications for the 120000 µF, 63 V configuration, making them functionally equivalent.
