Engineering Selection Recommendations

Direct Replacement (Same Voltage Rating - 16 V):

EEE-FK1C331P is the primary direct equivalent. It maintains identical electrical specifications and physical dimensions while offering active product status and RoHS3 compliance. This part is recommended for direct substitution in existing designs.

EEE-FK1C331AL provides the same electrical performance with halogen-free composition, suitable for applications requiring environmental compliance beyond standard RoHS requirements.

EEE-FK1C331GP extends the lifetime rating to 5000 Hrs @ 105°C while maintaining 16 V rating, providing enhanced reliability for long-life automotive applications.

EEE-FP1C331AP offers reduced ESR (80 mOhms vs. 160 mOhms) and increased ripple current capability (850 mA vs. 600 mA @ 100 kHz), suitable for applications with higher AC ripple current demands.

Voltage Upgrade Options (25 V and 35 V Ratings):

Parts rated at 25 V (EEE-FK1E331P, EEE-FK1E331AP, EEE-FK1E331GP, EEE-FP1E331AP) and 35 V (EEE-FT1V331AP, EEE-FT1V331GP) are electrically compatible substitutes that provide increased voltage margin. These are suitable for designs where the original 16 V rating may be marginal or where circuit redesign allows higher voltage tolerance. All maintain identical physical footprints and capacitance values.

All substitute parts carry AEC-Q200 automotive certification and RoHS3 compliance, ensuring suitability for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C331P be used as a direct replacement for EEV-FK1C331P?

A: Yes. EEE-FK1C331P is the direct equivalent with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and physical dimensions. The primary difference is product status (active vs. obsolete) and RoHS3 compliance.

Q: What is the difference between FK and FP series capacitors?

A: The FK series has 160 mOhms ESR and 600 mA ripple current @ 100 kHz. The FP series has lower ESR (80 mOhms) and higher ripple current capability (850 mA @ 100 kHz). FP series is suitable for applications requiring lower impedance or higher AC ripple current handling.

Q: Can I use a 25 V rated capacitor in place of a 16 V rated capacitor?

A: Yes, from an electrical standpoint. A 25 V capacitor can operate safely in a 16 V circuit. However, verify that the physical dimensions remain compatible with your PCB layout, as some 25 V variants may have different heights. All listed 25 V options maintain the same 0.315" diameter and land size as the original part.

Q: What does the "G" suffix in part numbers like EEE-FK1C331GP indicate?

A: The "G" suffix indicates an extended lifetime rating of 5000 Hrs @ 105°C, compared to the standard 2000 Hrs @ 105°C. This provides improved reliability for long-life applications.

Q: Are all substitute parts AEC-Q200 certified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.

Q: What packaging options are available?

A: EEE-FK1C331P is supplied in Tape & Reel (TR) packaging. EEE-FP1C331AP is available in Cut Tape (CT) & Digi-Reel packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Is the halogen-free variant (EEE-FK1C331AL) electrically identical to the standard FK series?

A: Yes. EEE-FK1C331AL maintains identical electrical specifications, ESR, ripple current, and physical dimensions. The halogen-free composition is a material property that does not affect electrical performance.
