Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Active Status): EEE-TC1A471P, EEE-TG1A471UP, EEE-TK1A471UP, and EEE-TP1A471AP are active Panasonic alternatives with identical 470 µF, 10 V specifications. All are ROHS3 compliant and AEC-Q200 qualified. EEE-TC1A471P and EEE-TP1A471AP offer extended operating temperature to 125°C with 3000-hour lifetime ratings, providing improved thermal margin. EEE-TG1A471UP maintains the original 0.402" height and offers 2000-hour lifetime at 125°C. Selection among these depends on thermal performance requirements and ripple current capacity.

For Voltage Upgrade (Higher Voltage Rating): EEE-TP1C471AP (16 V) and EEE-FK1E471P, EEE-FK1E471AP, EEE-FK1E471GP (25 V) are suitable when circuit design permits higher voltage ratings. These parts maintain 470 µF capacitance and ±20% tolerance while providing voltage margin. EEE-FK series parts extend operating temperature to -55°C to 105°C and offer superior lifetime ratings (2000 to 5000 hours at 105°C). Height increases to 0.413" for FK series; verify PCB layout clearance. All are ROHS3 compliant and AEC-Q200 qualified.

For Legacy Support (Same Series, Voltage Upgrade): EEE-1CA471P and EEE-1CA471AP are Series S parts with 16 V rating, maintaining the original 0.402" height and -40°C to 85°C operating range. These are Not For New Designs but provide compatibility for existing designs requiring voltage upgrade within the same thermal envelope.

Recommended Primary Selection: EEE-FK1E471P is the manufacturer-recommended substitute, offering active product status, ROHS3 compliance, AEC-Q200 qualification, and extended thermal performance (2000 Hrs @ 105°C). The 25 V rating provides design margin for 10 V applications.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1E471P replace EEE-1AA471P directly on the PCB? A: Yes, with height verification. EEE-FK1E471P has identical case diameter (10.00mm) and land size (10.30mm x 10.30mm) but increased height of 0.413" versus 0.402". Confirm PCB clearance above the component before substitution.

Q: What is the difference between EEE-TC1A471P and EEE-TP1A471AP? A: Both are 470 µF, 10 V active alternatives with 3000-hour lifetime at 125°C. EEE-TC1A471P specifies 150 mOhm ESR at 100 kHz and higher ripple current capacity (750 mA @ 100 kHz). EEE-TP1A471AP does not specify ESR. Selection depends on ripple current requirements in the application.

Q: Why does EEE-FK1E471GP have higher inventory than EEE-FK1E471P? A: EEE-FK1E471GP offers 5000-hour lifetime at 105°C versus 2000 hours for EEE-FK1E471P, making it suitable for extended-life applications. Higher inventory reflects broader market demand for long-life automotive capacitors.

Q: Are all substitute parts AEC-Q200 qualified? A: EEE-TC1A471P, EEE-TP1A471AP, EEE-TP1C471AP, and all EEE-FK series parts are AEC-Q200 qualified. EEE-TG1A471UP and EEE-TK1A471UP do not list AEC-Q200 rating; verify qualification requirements for your application.

Q: Can I use a 25 V rated capacitor in a 10 V circuit? A: Yes. Higher voltage ratings are acceptable in lower voltage applications. EEE-FK series 25 V parts are suitable for 10 V circuits and provide voltage margin. Verify that the increased height (0.413" for FK series) does not exceed PCB clearance limits.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant? A: ROHS3 Compliant represents the current RoHS 3 directive standard and is preferred for new designs. RoHS Compliant indicates compliance with earlier RoHS standards. Both meet environmental requirements; ROHS3 is recommended for ongoing production.

Q: Which substitute offers the best thermal performance? A: EEE-FK1E471GP provides the highest thermal rating with 5000-hour lifetime at 105°C and extended operating range (-55°C to 105°C). For applications requiring maximum thermal margin, this part is the optimal choice.
