Substitute parts are grouped into two categories:

Category 1: Direct Equivalents (Same Voltage Rating - 6.3 V)

EEE-FC0J331AP: Identical electrical and mechanical specifications with enhanced high-temperature reflow capability

Category 2: Upgraded Substitutes (Higher Voltage Ratings - 10 V and 16 V)

EEE-FK1A331AP, EEE-FK1A331GP, EEE-FK1A331P (10 V rated)
EEE-FK1C331AP, EEE-FK1C331GP, EEE-FK1C331P (16 V rated)

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications): EEE-FC0J331AP is the direct equivalent to EEE-FC0J331P. Both parts share identical capacitance, voltage rating, tolerance, and physical dimensions. EEE-FC0J331AP is preferred where available due to enhanced high-temperature reflow capability, though both are classified as "Not For New Designs."

For New Designs and Long-Term Supply Assurance: Active product status parts from the FK and FP series are recommended:

EEE-FK1A331AP, EEE-FK1A331P (10 V, 2000 Hrs @ 105°C) for standard applications
EEE-FK1A331GP (10 V, 5000 Hrs @ 105°C) for extended lifetime requirements
EEE-FK1C331AP, EEE-FK1C331P (16 V, 2000 Hrs @ 105°C) for higher voltage margin
EEE-FK1C331GP (16 V, 5000 Hrs @ 105°C) for extended lifetime with higher voltage rating

For Low-ESR Applications: EEE-FP1A331AP (10 V) and EEE-FP1C331AP (16 V) provide 80 mOhms ESR at 100 kHz, compared to 160 mOhms in FK series, suitable for high-frequency ripple current applications.

All recommended substitutes maintain AEC-Q200 automotive qualification and RoHS3 compliance. Physical dimensions remain compatible with existing PCB layouts, with maximum height of 10.50mm for FK and FP series (compared to 10.20mm for FC series).

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1A331AP be used as a direct replacement for EEE-FC0J331P? A: Yes. EEE-FK1A331AP is electrically compatible. It provides 10 V rating (higher than the 6.3 V requirement), identical 330 µF capacitance, ±20% tolerance, and compatible physical dimensions. The 10 V rating provides additional design margin without affecting circuit operation in 6.3 V applications.

Q: What is the difference between EEE-FK1A331AP and EEE-FK1A331GP? A: Both parts are 330 µF, 10 V rated with identical physical dimensions. The primary difference is lifetime: EEE-FK1A331AP is rated for 2000 hours at 105°C, while EEE-FK1A331GP is rated for 5000 hours at 105°C. Selection depends on required operational lifetime.

Q: Why do FK and FP series parts have different heights (10.50mm vs 10.20mm)? A: FK series parts have a maximum seated height of 10.50mm, while FP series parts are 10.20mm. Both are compatible with the original 10.20mm land size specification. Height difference reflects internal construction variations between series. Verify PCB clearance before substitution if height-constrained.

Q: Are all substitute parts AEC-Q200 rated? A: Yes. All substitute parts listed maintain AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.

Q: What is the difference between RoHS and ROHS3 compliance? A: Both indicate RoHS compliance. ROHS3 represents the current RoHS 3 directive compliance status. All parts listed are RoHS compliant and suitable for applications requiring RoHS certification.

Q: Can EEE-HA1C331UP be used as a substitute? A: EEE-HA1C331UP is electrically compatible (330 µF, 16 V, ±20% tolerance) with identical physical dimensions. However, it is classified as "Not For New Designs" and has 1000-hour lifetime at 105°C. It is suitable only for direct replacement in existing designs; active product alternatives (FK or FP series) are preferred for new applications.

Q: What is the significance of impedance values in the comparison? A: Impedance affects ripple current handling and high-frequency performance. FK series parts have 160 mOhms impedance, while FP series parts have 80 mOhms at 100 kHz. Lower impedance (FP series) is beneficial for applications with high ripple current or high-frequency switching. Standard impedance (FK series) is suitable for general applications.

Q: Are there any packaging differences between substitute parts? A: EEE-FC0J331P and EEE-FC0J331AP are supplied in Tape & Reel (TR) packaging. EEE-FP1C331AP is supplied in Cut Tape (CT) & Digi-Reel® packaging. All other substitutes use Tape & Reel (TR). Verify packaging requirements for automated assembly processes.
