Engineering Selection Recommendations

Panasonic FK Series (EEE-FK1A221AP, EEE-FK1A221P, EEE-FK1C221AP, EEE-FK1C221P): These parts are direct active-status replacements with doubled lifetime (2000 Hrs @ 105°C), extended operating temperature range (-55°C ~ 105°C), and ROHS3 compliance. The 10 V and 16 V voltage options provide circuit margin over the original 6.3 V rating. Footprint compatibility is maintained with standard 8.30mm x 8.30mm land size. Height increases from 6.20mm to 6.50mm; verify PCB clearance.

Panasonic FP Series (EEE-FP1A221AP, EEE-FP1C221AP): These parts offer the same 220 µF capacitance and 2000 Hrs @ 105°C lifetime as FK series with lower ESR (180 mOhm @ 100 kHz) and higher ripple current capability (500 mA @ 100 kHz). Height remains at 6.20mm, matching the original part. Available in 10 V and 16 V ratings.

Panasonic HB Series (EEE-HBA221UAP): This part maintains the original 6.20mm height and -40°C ~ 105°C operating range while providing 2000 Hrs @ 105°C lifetime and 10 V rating. Suitable for designs where height constraint is critical and temperature range matches the original specification.

Panasonic TG Series (EEE-TG1A221UP): This part is specified for high-temperature operation (1000 Hrs @ 125°C, -40°C ~ 125°C range) with 10 V rating and 6.20mm height. Select for applications requiring extended temperature performance beyond standard 105°C.

Cornell Dubilier AFK Series (AFK227M10E16T-F, AFK227M16E16T-F): These parts provide 2000 Hrs @ 105°C lifetime, -55°C ~ 105°C operating range, and 260 mOhm ESR @ 100 kHz. Land size is 8.30mm x 9.50mm (width increased to 9.50mm); verify PCB layout compatibility before selection. Available in 10 V and 16 V ratings.

All substitute parts maintain AEC-Q200 automotive qualification and RoHS compliance. Selection should prioritize active-status parts (FK, FP, HB, TG series) over the obsolete FC series.

Frequently Asked Questions (FAQ)

Q: Can EEE-FC0J221P be directly replaced with a higher voltage-rated substitute?

A: Yes. Voltage uprating is a valid substitution strategy. A 10 V or 16 V rated capacitor will function correctly in a circuit designed for 6.3 V operation, providing additional safety margin. The capacitance (220 µF) and tolerance (±20%) remain identical, ensuring circuit performance is maintained.

Q: What is the impact of height difference between EEE-FC0J221P (6.20mm) and FK series (6.50mm)?

A: The 0.30mm height increase must be verified against PCB clearance constraints, particularly in space-constrained applications or where components are mounted near other tall components. If clearance is insufficient, select FP series (6.20mm height) or HB series (6.20mm height) as alternatives.

Q: Are Panasonic and Cornell Dubilier parts interchangeable?

A: Panasonic and Cornell Dubilier parts are electrically and mechanically compatible for the 220 µF, ±20%, 10 V and 16 V ratings. However, Cornell Dubilier AFK series has a wider land size (9.50mm width vs. 8.30mm). Verify PCB layout compatibility before substitution.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied in smaller quantities on cut strips, suitable for low-volume or prototype applications. Tape & Reel packaging is supplied on continuous reels for high-volume automated assembly. Both formats contain identical components; selection depends on production volume and assembly equipment capability.

Q: Why does EEE-TG1A221UP specify 1000 Hrs @ 125°C instead of 105°C?

A: The TG series is designed for high-temperature applications. The 1000 Hrs @ 125°C rating indicates the capacitor maintains specified performance at elevated temperature (125°C) for 1000 hours. This differs from standard ratings at 105°C and is suitable for automotive under-hood or other high-temperature environments.

Q: Can I use EEE-FK1C221P (16 V) in place of EEE-FC0J221P (6.3 V)?

A: Yes. The FK1C221P provides higher voltage rating (16 V), doubled lifetime (2000 Hrs @ 105°C), extended temperature range (-55°C ~ 105°C), and active product status. All mechanical and electrical parameters are compatible. This is a recommended upgrade path for new designs or production updates.
