Frequently Asked Questions (FAQ)

Q: Can the ALS70A623NP100 be used as a direct replacement for the ALS71A623NP100?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (capacitance, voltage, ESR, ripple current, lifetime), mechanical dimensions (diameter, height, lead spacing), and compliance certifications (RoHS3, REACH). Direct substitution is supported without circuit modification.

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

A: No. Both parts use identical radial, can-style screw terminal packaging with 1.252" (31.80mm) lead spacing. Terminal compatibility is equivalent.

Q: Do both parts have the same operating temperature range?

A: Yes. Both the ALS71A623NP100 and ALS70A623NP100 operate across -40°C to 85°C with identical 20000-hour lifetime ratings at 85°C.

Q: What is the significance of the series designation difference (ALS71 vs. ALS70)?

A: The series designation reflects internal KEMET product line organization. For the 62000 µF, 100 V specification, both series deliver identical electrical performance and mechanical form factors. The series difference does not impact substitution eligibility.

Q: Are both parts suitable for chassis mount applications?

A: Yes. Both parts are specified for chassis mount installation with identical mechanical dimensions and screw terminal interfaces.

Q: What is the tolerance range for the 62000 µF capacitance value?

A: Both parts carry ±20% tolerance, resulting in a capacitance range of 49600 µF to 74400 µF at rated conditions.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial component applications.
