Parameter Comparison

Engineering Selection Recommendations

EEE-FK2A331AM (Direct Equivalent): This part is electrically and mechanically equivalent to the main part number EEE-FK2A331AV. The height specification of 0.669" (17.00 mm) is within the acceptable range for the 0.748" x 0.748" land pattern. All electrical parameters, compliance certifications, and automotive ratings are identical. This part is suitable for direct substitution in all applications where EEE-FK2A331AV is specified.

EEV-FK2A331V (Upgrade Equivalent): This part maintains identical electrical specifications, mechanical dimensions, and compliance certifications as the main part. The EEV series designation indicates an alternative Panasonic product line with equivalent performance characteristics. The anti-vibration designation is present in both the main part and this substitute, indicating similar mechanical robustness for automotive applications. This part is suitable for direct substitution.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and high-temperature reflow manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK2A331AM be used as a direct replacement for EEE-FK2A331AV?

A: Yes. Both parts meet identical electrical specifications (330 µF, 100 V, ±20%, 5000 Hrs @ 105°C), mechanical dimensions (18.00 mm diameter, 19.00 mm x 19.00 mm land pattern), and compliance requirements (AEC-Q200, ROHS3, MSL 1). The height difference of 0.004" (0.10 mm) is within acceptable PCB assembly tolerances.

Q: What is the difference between the FK and EV series designations?

A: Both FK and EV series are Panasonic aluminum electrolytic capacitor lines. The EEE-FK2A331AV and EEV-FK2A331V are equivalent products with identical electrical and mechanical parameters. Series designation reflects internal Panasonic product categorization but does not affect functional compatibility.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, confirming suitability for automotive applications requiring temperature cycling, vibration resistance, and reliability testing per automotive standards.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the PCB land pattern is designed for the 0.748" x 0.748" (19.00 mm x 19.00 mm) surface mount footprint and the assembly process accommodates the maximum height of 0.673" (17.10 mm). All substitute parts meet these specifications.

Q: What is the significance of the anti-vibration designation?

A: The anti-vibration designation indicates enhanced mechanical robustness for applications subject to vibration stress. Both EEE-FK2A331AV and EEV-FK2A331V carry this designation, confirming suitability for automotive environments with vibration exposure.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special drying or baking requirements.
