Frequently Asked Questions (FAQ)

Q: Can ALA7DA301CC450 be used as a direct replacement for ALA7DF301CC450?

A: Yes. Both parts are manufactured by KEMET in the ALA7D series with identical electrical parameters (300 µF, 450 V, ±20% tolerance), ESR characteristics (504.2 mOhm @ 100Hz), lifetime rating (13000 Hrs @ 85°C), and mechanical dimensions (30.00 mm diameter, 37.00 mm height). They are fully interchangeable in all applications.

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

A: The ripple current specifications differ between the two parts. ALA7DF301CC450 has ripple current ratings of 2.26 A @ 100 Hz and 6.01 A @ 10 kHz. ALA7DA301CC450 has ripple current ratings of 2.12 A @ 100 Hz and 4.12 A @ 10 kHz. Applications requiring specific ripple current performance should verify compatibility with the selected part number.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both ALA7DF301CC450 and ALA7DA301CC450 carry AEC-Q200 automotive qualification ratings and are suitable for automotive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for automotive and industrial use.

Q: What is the mounting configuration for these capacitors?

A: Both parts are through-hole mounted, radial, can-style snap-in capacitors with identical physical dimensions of 30.00 mm diameter and 37.00 mm maximum seated height. They are designed for direct insertion into PCB snap-in mounting positions.

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

A: Yes, provided the application does not have specific ripple current requirements that exceed the ratings of the substitute part. The identical capacitance, voltage rating, tolerance, ESR, and physical dimensions ensure mechanical and electrical compatibility in all standard filtering and energy storage applications.
