Engineering Selection Recommendations

For Direct Replacement (Same Footprint & Performance): EEE-FC1V331AP is the direct equivalent with identical specifications and packaging. Both parts are classified "Not For New Designs," making this suitable only for legacy system maintenance.

For Active Product Upgrade (Improved Reliability): EEE-FK1V331P or EEE-FK1V331AP provide doubled lifetime (2000 hours) with lower impedance (80 mOhms vs. 150 mOhms) and higher ripple current capability (850 mA vs. 670 mA). These parts are Active status and ROHS3 compliant. Height increases from 0.402" to 0.413", requiring PCB layout verification.

For Extended Lifetime Applications: EEE-FK1V331GP and EEE-FT1H331GP offer 5000-hour lifetime ratings at 105°C, suitable for mission-critical automotive applications. Both maintain AEC-Q200 qualification and ROHS3 compliance.

For Superior Ripple Current Performance: EEE-FP1V331AP delivers the lowest impedance (60 mOhms) and highest ripple current (1.19 A @ 100 kHz) while maintaining the original 0.402" height. Active status and ROHS3 compliant.

For Higher Voltage Margin: EEE-FT1H331AP and EEE-FT1H331GP provide 50 V rating (vs. 35 V) with extended lifetime options. These are suitable when circuit design permits voltage derating for enhanced safety margins.

For Cross-Manufacturer Sourcing: 35JZV330M10X10.5 (Rubycon) meets all electrical and mechanical requirements with 2000-hour lifetime, 90 mOhms impedance, and ROHS3 compliance. Suitable for supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1V331P be used as a direct drop-in replacement for EEE-FC1V331P?

A: Electrically yes, mechanically requires verification. The FK series has a maximum height of 0.413" compared to 0.402" for the FC series. PCB layout must accommodate the additional 0.011" height. All other dimensions and land sizes are identical.

Q: What is the difference between EEE-FK1V331AP and EEE-FK1V331P?

A: Both are FK series parts with identical electrical specifications and 2000-hour lifetime. The primary difference is packaging: EEE-FK1V331AP is supplied in Tape & Reel (TR), while EEE-FK1V331P is also supplied in Tape & Reel (TR). Inventory levels differ significantly (3454 vs. 18597 units).

Q: Why would I choose EEE-FP1V331AP over EEE-FK1V331P?

A: EEE-FP1V331AP offers superior electrical performance with 60 mOhms impedance (vs. 80 mOhms) and 1.19 A ripple current capability (vs. 850 mA). It maintains the original 0.402" height, eliminating PCB layout concerns. Both have 2000-hour lifetime and Active status.

Q: Is EEE-FT1H331AP compatible with a 35 V circuit design?

A: Yes. EEE-FT1H331AP is rated for 50 V, which exceeds the 35 V requirement. This provides additional voltage margin and safety factor. The part is electrically and mechanically compatible, though height increases to 0.413".

Q: Can I use a 50 V rated capacitor in place of a 35 V rated capacitor?

A: Yes. Higher voltage ratings are acceptable substitutes. The 50 V rated EEE-FT1H331AP and EEE-FT1H331GP parts can replace 35 V applications without electrical or safety concerns.

Q: What does "Not For New Designs" mean for EEE-FC1V331P?

A: This designation indicates the part has been superseded and is no longer recommended for new product development. It remains available for existing production and legacy system support. Active alternatives such as EEE-FK1V331P or EEE-FP1V331AP are recommended for new designs.

Q: Are all substitute parts AEC-Q200 qualified?

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

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents the current RoHS Directive 2011/65/EU standard. Parts marked RoHS Compliant meet the original directive. ROHS3 compliant parts meet the updated standard and are preferred for new designs. Both are acceptable for substitution.

Q: Can I substitute the Rubycon 35JZV330M10X10.5 for the Panasonic EEE-FC1V331P?

A: Yes. The Rubycon part meets all electrical, mechanical, and compliance requirements. It offers improved performance with 2000-hour lifetime, 90 mOhms impedance, and 850 mA ripple current. Cross-manufacturer substitution is suitable for supply chain flexibility.

Q: What is the difference between ripple current @ 120 Hz and @ 100 kHz?

A: These measurements reflect capacitor performance at different frequencies. Low-frequency ripple current (120 Hz) is typically lower; high-frequency ripple current (100 kHz) is higher. Both specifications must be evaluated against circuit requirements. The EEE-FP1V331AP excels in both metrics.
