Frequently Asked Questions (FAQ)

Q: Are the ALS70C513NF100 and ALS70A513NF100 directly interchangeable?

A: Yes. Both parts are identical in all electrical parameters (capacitance, voltage rating, ESR, ripple current, lifetime) and mechanical specifications (package type, dimensions, lead spacing, mounting configuration). Direct substitution is supported without circuit modification.

Q: What is the difference between the ALS70C and ALS70A base product numbers?

A: The base product numbers ALS70C and ALS70A represent different internal product variants within the KEMET ALS70 series. However, for the 513NF100 configuration, both variants maintain identical electrical and mechanical specifications, making them functionally equivalent.

Q: Can these capacitors be used in high-frequency applications?

A: These capacitors are rated for ripple current operation at both low frequency (25.7 A @ 100 Hz) and high frequency (27.9 A @ 10 kHz). The ESR of 12 mOhm @ 100Hz supports both frequency ranges within the specified ripple current limits.

Q: What are the storage and handling requirements?

A: Both parts carry MSL Level 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard component storage practices at controlled temperature and humidity are sufficient.

Q: Are these parts suitable for automotive or industrial applications?

A: These parts are classified for general purpose applications. Suitability for specific automotive or industrial applications must be determined based on application-specific requirements and any additional qualification standards required by the end-use industry.

Q: What is the expected operational lifetime?

A: Both parts are rated for 20000 hours of operation at 85°C. Actual lifetime depends on operating conditions, including ambient temperature, ripple current loading, and voltage stress.
