Engineering Selection Recommendations

Direct Substitutes (Same Voltage, Active Status):

EEE-FK1A221XP and EEE-FKA221XAP are direct substitutes for 10 V applications. Both maintain 220 µF capacitance and ±20% tolerance with identical land size compatibility. These parts upgrade the operating temperature range to -55°C to 105°C and extend lifetime rating to 2000 hours at 105°C. Product status is Active, making them suitable for new designs.

EEE-FPA221XAP provides an alternative 10 V substitute with Active status, extended temperature range, and improved lifetime rating while maintaining the original 7.70 mm height.

Voltage-Upgraded Substitutes (Higher Voltage, Active Status):

EEE-FKC221XAP, EEE-FN1C221XP, EEE-FK1C221XP, and EEE-FPC221XAP are 16 V rated substitutes. These parts are electrically compatible in 10 V circuits and provide additional voltage margin. All carry Active status and extended operating temperature ranges. EEE-FK1C221XP offers the highest inventory availability at 137,144 pieces.

EEE-FTE221XAP is a 25 V rated substitute offering maximum voltage margin for applications requiring additional design safety.

Legacy Compatibility (Same Series, Not For New Designs):

EEE-1CA221XAP and EEE-1CA221XP maintain the original S series and 7.70 mm height with 16 V rating. These parts share the same operating temperature and lifetime specifications as the original but carry Not For New Designs status.

Recommended Selection Criteria:

For new production and design implementations, select from Active status parts. EEE-FK1C221XP is recommended for highest availability and extended reliability specifications. For space-constrained applications requiring the original 7.70 mm height, EEE-FPA221XAP or EEE-FPC221XAP are suitable alternatives.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1A221XP replace EEE-1AA221XP directly?

A: Yes. Both parts maintain 220 µF capacitance, ±20% tolerance, 10 V rating, and identical land size (6.60 mm x 6.60 mm). EEE-FK1A221XP has a maximum height of 8.00 mm compared to the original 7.70 mm. Verify PCB clearance before substitution. EEE-FK1A221XP offers improved reliability with extended temperature range and higher lifetime rating.

Q: What is the difference between 10 V and 16 V rated substitutes?

A: 16 V rated parts (EEE-FKC221XAP, EEE-FN1C221XP, EEE-FK1C221XP, EEE-FPC221XAP) are electrically compatible in circuits designed for 10 V operation. The higher voltage rating provides additional design margin and is a direct upgrade. No circuit modifications are required.

Q: Why do some substitutes have different heights?

A: FK and FT series parts have a maximum height of 8.00 mm, while FP and S series parts maintain 7.70 mm. Height differences result from internal construction and thermal performance improvements. Verify PCB layout clearance before selecting a substitute with different height specifications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, matching the original part's certification level.

Q: What does "Not For New Designs" status mean?

A: Parts with Not For New Designs status are available for existing production but should not be selected for new circuit designs. Active status parts are recommended for all new implementations.

Q: Can I use a 25 V rated part instead of 10 V?

A: Yes. EEE-FTE221XAP at 25 V rating is electrically compatible in 10 V circuits and provides maximum voltage margin. No circuit modifications are required.

Q: Which substitute offers the best availability?

A: EEE-FK1C221XP has the highest inventory at 137,144 pieces and is rated for 16 V with Active status and extended temperature specifications.
