Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1K3R3R be used as a direct replacement for the AFK335M80C12B-F?

A: Yes. The EEE-FK1K3R3R meets all electrical and mechanical specifications of the AFK335M80C12B-F, including capacitance, voltage rating, temperature range, ripple current ratings, physical dimensions, and package type. Both components are AEC-Q200 rated and ROHS3 compliant.

Q: Are there any differences in the surface mount land pattern between these two parts?

A: The AFK335M80C12B-F specifies a surface mount land size of 0.209" L x 0.256" W (5.30mm x 6.50mm). The EEE-FK1K3R3R specifies 0.209" L x 0.209" W (5.30mm x 5.30mm). The width dimension differs by 0.047" (1.20mm). PCB layout verification is required to confirm land pattern compatibility with existing designs.

Q: What is the difference in ESR between these parts?

A: The AFK335M80C12B-F specifies ESR of 5 Ohms @ 100 kHz. The EEE-FK1K3R3R does not provide an ESR specification in the available data. Both parts specify identical impedance of 5 Ohms, which is the primary electrical parameter for circuit performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the AFK335M80C12B-F and EEE-FK1K3R3R carry AEC-Q200 automotive qualification and are rated for the same operating temperature range of -55°C ~ 105°C with 2000 hours lifetime at 105°C.

Q: What is the difference in packaging between these parts?

A: The EEE-FK1K3R3R is supplied in Tape & Reel (TR) packaging. The AFK335M80C12B-F packaging format is not specified in the provided data. Tape & Reel packaging is standard for automated surface mount assembly.

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

A: Electrical substitution is direct. Mechanical compatibility requires verification of the surface mount land pattern dimensions, as noted in the land size specifications. The physical diameter and height are identical between both parts.
