Frequently Asked Questions (FAQ)

Q: Can ALS71A123MF200 be used as a direct replacement for ALS71C123MF200?

A: Yes. The ALS71A123MF200 is a parametric equivalent with identical capacitance, voltage rating, tolerance, ESR, lifetime rating, operating temperature range, ripple current specifications, and physical dimensions. Both parts are housed in radial, can-style screw terminal packages with chassis mount configuration.

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts share identical electrical specifications: 12000 µF capacitance, 200 V rating, ±20% tolerance, 29 mOhm ESR @ 100 Hz, 19000 hours lifetime @ 85°C, and equivalent ripple current ratings at both low and high frequencies.

Q: Do both parts have the same physical footprint?

A: Yes. Both the ALS71C123MF200 and ALS71A123MF200 have identical lead spacing (1.122" / 28.50 mm), diameter (2.598" / 66.00 mm), and maximum seated height (4.213" / 107.00 mm). They are mechanically interchangeable in chassis-mount applications.

Q: What is the difference between the ALS71C and ALS71A base product numbers?

A: The base product numbers (ALS71C versus ALS71A) indicate different product variants within the KEMET ALS71 series. However, when paired with identical capacitance, voltage, and tolerance specifications (123MF200), both variants deliver equivalent performance and are substitutable.

Q: Are both parts compliant with RoHS and REACH regulations?

A: Yes. Both the ALS71C123MF200 and ALS71A123MF200 are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
