Engineering Selection Recommendations

Direct Voltage Equivalent (10 V):

EEE-FK1A331GP and EEE-FK1A331P are the primary substitutes for the EEE-1AA331AP. Both maintain 10 V voltage rating and 330 µF capacitance with identical physical footprint. The FK series offers Active product status, extended operating temperature range (-55°C ~ 105°C), and improved thermal performance. EEE-FK1A331GP provides 5000 hours lifetime at 105°C, while EEE-FK1A331P provides 2000 hours at 105°C. Both are ROHS3 Compliant and AEC-Q200 rated.

EEE-TG1A331UP is an alternative 10 V substitute with Active status, offering the highest operating temperature range (-40°C ~ 125°C) and 2000 hours lifetime at 125°C. This part is suitable for applications requiring extended high-temperature performance.

Higher Voltage Alternatives (16 V, 25 V, 35 V):

EEE-1CA331UP maintains the S series designation and Not For New Designs status with 16 V rating. This part is electrically compatible but does not advance product lifecycle status.

EEE-FK1C331GP and EEE-FK1C331P provide 16 V rating with Active status, extended temperature range, and improved lifetime ratings. EEE-FK1E331GP and EEE-FK1E331P offer 25 V rating with identical performance characteristics.

EEE-FT1V331AP and EEE-FT1V331GP provide the highest voltage rating at 35 V with Active status and extended thermal performance. These are suitable for applications requiring voltage margin or operating in elevated temperature environments.

All substitute parts maintain AEC-Q200 automotive qualification and RoHS compliance. Selection should prioritize Active status parts for new designs and applications requiring extended product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1A331GP directly replace EEE-1AA331AP in existing designs?

A: Yes. Both parts maintain identical 330 µF capacitance, ±20% tolerance, 10 V voltage rating, and physical dimensions (0.315" Dia, 0.402" height maximum, 0.327" x 0.327" land size). The FK series offers improved thermal performance and Active product status. No circuit modifications are required.

Q: What is the difference between EEE-FK1A331GP and EEE-FK1A331P?

A: Both parts are identical except for lifetime rating. EEE-FK1A331GP is rated for 5000 hours at 105°C, while EEE-FK1A331P is rated for 2000 hours at 105°C. Selection depends on application lifetime requirements.

Q: Can I use a 16 V or 25 V rated part instead of the 10 V original?

A: Yes. Higher voltage rated parts (EEE-1CA331UP, EEE-FK1C331GP, EEE-FK1C331P, EEE-FK1E331GP, EEE-FK1E331P) are electrically compatible substitutes. They maintain identical capacitance, tolerance, and physical footprint while providing voltage margin. This is acceptable for applications where the circuit voltage does not exceed the original 10 V specification.

Q: What is the height difference between S series and FK series parts?

A: S series parts (EEE-1AA331AP, EEE-1CA331UP) have a maximum seated height of 0.402" (10.20mm). FK series parts (EEE-FK1A331GP, EEE-FK1A331P, EEE-FK1C331GP, EEE-FK1C331P, EEE-FK1E331GP, EEE-FK1E331P) have a maximum seated height of 0.413" (10.50mm). This 0.011" (0.30mm) difference must be verified against PCB layout constraints.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification. RoHS compliance is maintained across all parts, with newer series (FK, FT, TG) offering ROHS3 Compliant status.

Q: Which substitute offers the widest operating temperature range?

A: EEE-TG1A331UP offers the widest operating temperature range of -40°C ~ 125°C with 2000 hours lifetime at 125°C. This part is suitable for applications requiring extended high-temperature performance beyond the original -40°C ~ 85°C specification.

Q: What packaging options are available for substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) packaging except EEE-TG1A331UP, which is supplied in Cut Tape (CT) & Digi-Reel® packaging. Packaging selection should align with assembly process requirements.
