Engineering Selection Recommendations

For Direct Replacement (Same Voltage, 16 V):

EEE-TP1C471AP is the preferred direct replacement. It maintains the 16 V voltage rating and ±20% tolerance while offering Active product status, ROHS3 compliance, and extended thermal performance (3000 Hrs @ 125°C). The operating temperature range extends to 125°C, providing margin for high-temperature applications. Height remains at 0.402" (10.20mm), ensuring PCB compatibility without layout modifications.

EEE-TC1C471P is an alternative direct replacement with identical electrical specifications but slightly increased height (0.413" vs. 0.402"). This part also provides 3000 Hrs @ 105°C lifetime and Active status.

EEE-HB1C471AP offers 2000 Hrs @ 105°C lifetime with Active status and ROHS3 compliance, suitable for applications requiring moderate thermal enhancement without extended lifetime requirements.

For Voltage-Upgraded Substitution (25 V):

EEE-FK1E471GP is the recommended upgrade option, offering 5000 Hrs @ 105°C lifetime, the longest available in the 25 V category. This part provides maximum reliability margin and Active product status with ROHS3 compliance. The extended operating temperature range (-55°C ~ 105°C) accommodates wider environmental conditions.

EEE-FK1E471AP and EEE-FK1E471P provide 2000 Hrs @ 105°C with Active status and ROHS3 compliance. Both are suitable for applications where voltage headroom is required without extended lifetime demands.

EEE-FP1E471AP offers the lowest ESR (60 mOhm @ 100 kHz) among 25 V options and maintains the original height of 0.402" (10.20mm). This part is optimal for applications sensitive to ripple current performance.

For Voltage-Upgraded Substitution (35 V):

EEE-FN1V471UP is the manufacturer-recommended upgrade, providing 35 V rating with 2000 Hrs @ 105°C lifetime and Active product status. This part offers maximum voltage margin for circuit protection.

Avoid:

EEE-1EA471P and EEE-FK1V471SP are classified as "Not For New Designs" and should not be selected for new applications despite their availability.

Frequently Asked Questions (FAQ)

Q: Can EEE-1CA471P be replaced with a higher voltage-rated capacitor?

A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters remain identical: 470 µF capacitance, ±20% tolerance, 16 V minimum rating, identical package dimensions, and AEC-Q200 automotive rating. EEE-FK1E471AP (25 V) and EEE-FN1V471UP (35 V) are valid substitutes.

Q: What is the difference between EEE-TC1C471P and EEE-TP1C471AP?

A: Both are 16 V, 470 µF direct replacements with 3000 Hrs @ 125°C lifetime and Active status. The primary difference is height: EEE-TC1C471P is 0.413" (10.50mm) while EEE-TP1C471AP is 0.402" (10.20mm). Select EEE-TP1C471AP if PCB clearance is constrained; either part is electrically equivalent.

Q: Why does EEE-FK1E471GP have a longer lifetime than other 25 V options?

A: EEE-FK1E471GP is rated for 5000 Hrs @ 105°C compared to 2000 Hrs @ 105°C for other FK series parts. This extended lifetime reflects enhanced internal construction and is suitable for applications requiring maximum reliability over extended service intervals.

Q: Is the height difference between 0.402" and 0.413" critical?

A: Height difference is critical only if PCB layout includes height-constrained components or clearance requirements. Verify PCB design specifications before selecting parts with 0.413" height. Both heights are mechanically compatible with the standard 0.406" x 0.406" land pattern.

Q: Can EEE-FP1E471AP replace EEE-1CA471P despite different packaging?

A: EEE-FP1E471AP uses Cut Tape (CT) & Digi-Reel® packaging instead of Tape & Reel (TR). Electrically and mechanically, it is a valid substitute for 25 V applications. Verify supply chain compatibility and reel format requirements before selection.

Q: What does "Not For New Designs" mean for EEE-1CA471P?

A: This designation indicates the part has been superseded and is no longer recommended for new circuit designs. Existing inventory may remain available, but new designs should select Active-status alternatives such as EEE-TP1C471AP or EEE-FK1E471AP.

Q: Are all substitute parts AEC-Q200 rated?

A: Yes. All substitute parts listed maintain AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.
