Engineering Selection Recommendations

For Direct Replacement with Enhanced Thermal Performance: EEE-FK1C221XP, EEE-FKC221XAP, EEE-FN1C221XP, and 16TKV220M6.3X8 are recommended. These parts maintain 16 V rating and identical capacitance while extending operational temperature range to -55°C ~ 105°C and lifetime to 2000 hours at 105°C. All parts retain AEC-Q200 qualification and ROHS3 compliance.

For Compact Form Factor with Superior Ripple Current: EEE-FPC221XAP provides the same physical height as the original part (7.70mm) while delivering 160 mOhm ESR and 600 mA ripple current capability at 100 kHz. Product status is Active with ROHS3 compliance.

For Higher Voltage Margin: EEE-FTE221XAP offers 25 V rating with identical 220 µF capacitance and 6.30mm diameter, suitable for applications requiring increased voltage headroom. ESR is 160 mOhm with 600 mA ripple current at 100 kHz.

For Cross-Manufacturer Compatibility: Rubycon 16SEV220M6.3X8 provides equivalent electrical performance at 16 V with Active product status and AEC-Q200 qualification. Rubycon 16TKV220M6.3X8 offers enhanced thermal characteristics with 105°C lifetime rating.

Parts to Avoid for New Designs: EEE-1CA221P, EEE-1CA221UAP, and EEE-1CA221XAP carry Not For New Designs or reduced lifetime ratings and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C221XP directly replace EEE-1CA221XP without PCB modification? A: Yes. Both parts share identical capacitance (220 µF), voltage rating (16 V), tolerance (±20%), and surface mount radial can package. The FK series has a maximum height of 8.00mm versus 7.70mm for the original, which is within typical PCB clearance tolerances. Land pattern dimensions (6.60mm × 6.60mm) are identical.

Q: What is the primary advantage of EEE-FPC221XAP over EEE-FK1C221XP? A: EEE-FPC221XAP delivers superior electrical performance with 160 mOhm ESR and 600 mA ripple current capability at 100 kHz, compared to 340 mOhm ESR and 280 mA for FK series. Physical height matches the original part at 7.70mm. This upgrade reduces thermal stress and improves circuit stability in high-frequency applications.

Q: Is EEE-FTE221XAP suitable for 16 V circuits? A: Yes. EEE-FTE221XAP is rated for 25 V, which exceeds the 16 V requirement. The higher voltage rating provides additional safety margin without affecting circuit function. Capacitance, tolerance, package, and thermal characteristics remain equivalent to 16 V alternatives.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Both packaging formats contain identical components. Cut Tape (CT) is supplied in smaller quantities on cut strips, while Tape & Reel (TR) is supplied on continuous reels for high-volume automated assembly. Electrical and mechanical specifications are identical; selection depends on production volume and assembly equipment compatibility.

Q: Can Rubycon parts replace Panasonic parts in automotive applications? A: Yes. Both 16SEV220M6.3X8 and 16TKV220M6.3X8 carry AEC-Q200 qualification, meeting automotive reliability standards. Electrical specifications, package dimensions, and thermal ratings are equivalent to Panasonic alternatives. Cross-manufacturer substitution is qualified for automotive use.

Q: Why does EEE-1CA221UAP show Active status despite lower lifetime rating? A: EEE-1CA221UAP is rated for 1000 hours at 85°C versus 2000 hours for other S-series parts. This reduced lifetime rating reflects a different product variant within the same series. For applications requiring 2000-hour lifetime, select FK, FN, FP, or FT series alternatives.

Q: What is the significance of ESR specification in capacitor selection? A: Equivalent Series Resistance (ESR) determines voltage ripple attenuation and thermal dissipation. Lower ESR values (160 mOhm) reduce heat generation and improve high-frequency filtering performance compared to higher ESR values (340 mOhm). Selection depends on circuit ripple current requirements and thermal constraints.
