Engineering Selection Recommendations

Same Voltage Rating (25 V) - Active Alternatives:

EEE-TC1E331P, EEE-TG1E331UP, EEE-TK1E331UP, and EEE-TP1E331AP are all active production parts with 330 µF, 25 V specifications. These parts maintain the original voltage rating while offering extended operating temperature ranges (-40°C ~ 125°C) and improved lifetime ratings (2000-3000 hours at 125°C). All carry AEC-Q200 automotive qualification. EEE-TP1E331AP offers the highest inventory availability (77,325 pcs) and is available in Cut Tape & Digi-Reel packaging.

Higher Voltage Rating (35 V) - Manufacturer-Recommended Upgrade:

EEE-FK1V331AP and EEE-FK1V331P provide 35 V rating with identical 330 µF capacitance. These parts are manufacturer-recommended upgrades, offering improved voltage margin and extended operating temperature range (-55°C ~ 105°C). EEE-FK1V331GP extends the lifetime to 5000 hours at 105°C, providing enhanced reliability for demanding applications. All FK series parts maintain AEC-Q200 certification and are in active production.

Higher Voltage Rating (50 V) - Maximum Performance Alternative:

EEE-FT1H331AP and EEE-FT1H331GP offer 50 V rating with the same 330 µF capacitance. These parts provide the highest voltage margin and extended temperature range (-55°C ~ 105°C). EEE-FT1H331GP delivers 5000 hours lifetime at 105°C. Both are active production parts with AEC-Q200 certification.

Physical Compatibility Note:

Parts in the TC, TG, TK, TP series maintain the original 10.20mm height. Parts in the FK and FT series have 10.50mm height, requiring verification of PCB layout clearance. All parts share the same 10.00mm diameter and 10.30mm × 10.30mm land size.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct substitute?

A: Yes. A capacitor with higher voltage rating (35 V or 50 V) can replace the 25 V EEE-1EA331AP in the same circuit. Higher voltage rating provides additional safety margin and does not degrade circuit performance. The capacitance value (330 µF) and tolerance (±20%) remain the same.

Q: What is the difference between EEE-FK1V331AP and EEE-FK1V331GP?

A: Both are 330 µF, 35 V parts with identical physical dimensions and electrical characteristics. The primary difference is lifetime rating: EEE-FK1V331AP is rated for 2000 hours at 105°C, while EEE-FK1V331GP is rated for 5000 hours at 105°C. Select EEE-FK1V331GP for applications requiring extended operational life.

Q: Are there height differences between substitute parts?

A: Yes. The original EEE-1EA331AP has a maximum seated height of 10.20mm. Substitute parts in the TC, TG, TK, and TP series maintain this 10.20mm height. Parts in the FK and FT series have 10.50mm height. Verify PCB layout clearance before selecting parts with increased height.

Q: Which substitute part has the best availability?

A: EEE-TP1E331AP has the highest inventory (77,325 pcs) and is an active production part with 25 V rating, 3000 hours lifetime at 125°C, and AEC-Q200 certification. It is available in Cut Tape & Digi-Reel packaging.

Q: Can I use EEE-1VA331P as a substitute?

A: EEE-1VA331P is a 35 V upgrade option with the same physical dimensions as the original part (10.20mm height). However, it carries "Not For New Designs" status, similar to the original EEE-1EA331AP. For new designs, select active production alternatives such as EEE-FK1V331AP or EEE-TP1E331AP.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard for capacitors. All recommended substitute parts carry this certification, confirming suitability for automotive applications with validated reliability and performance standards.

Q: Are all substitute parts RoHS compliant?

A: The original EEE-1EA331AP is RoHS Compliant. All active production substitute parts (TC, TG, TK, TP, FK, FT series) are ROHS3 Compliant, meeting current environmental and regulatory requirements.
