Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Preferred):

The EEE-FTJ471XAL remains the recommended choice for new designs. This part carries Active product status, ensuring long-term availability and manufacturing support. It features the lowest ESR specification (160 mOhm @ 100 kHz) and highest ripple current ratings (390 mA @ 120 Hz, 600 mA @ 100 kHz), providing superior performance in high-frequency and high-ripple-current applications. The part is halogen-free and fully RoHS3 compliant.

Alternative Selection (Active Status):

The EEE-FTJ471XAP offers identical electrical performance to the primary part with the same 160 mOhm ESR and ripple current specifications. The only difference is packaging format: Cut Tape (CT) & Digi-Reel® instead of Tape & Reel (TR). This part maintains Active product status and is suitable for new designs when the alternative packaging format is acceptable.

The EEE-FNJ471XUL and EEE-FNJ471XUP are both Active status parts from the FN series. These parts feature 340 mOhm ESR and reduced ripple current ratings (182 mA @ 120 Hz, 280 mA @ 100 kHz). These substitutes are electrically compatible but operate with higher impedance and lower ripple current capacity. The EEE-FNJ471XUP offers higher inventory availability (9413 Pcs) compared to EEE-FNJ471XUL (2782 Pcs).

Legacy Selection (Not For New Designs):

The EEE-FKJ471XSL and EEE-FKJ471XSP are classified as Not For New Designs. These FKS series parts share the same 340 mOhm ESR and reduced ripple current specifications as the FN series alternatives. While electrically compatible, their legacy status restricts their use to replacement applications only. The EEE-FKJ471XSP offers higher inventory (4553 Pcs) than EEE-FKJ471XSL (2489 Pcs).

All substitute parts maintain AEC-Q200 automotive qualification, RoHS3 compliance, and identical physical dimensions and mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can EEE-FNJ471XUL or EEE-FNJ471XUP be used as direct replacements for EEE-FTJ471XAL?

A: Yes, these parts are electrically and mechanically compatible. All three maintain 470 µF capacitance, 6.3 V rating, ±20% tolerance, 2000 Hrs @ 105°C lifetime, and identical physical dimensions. The FN series parts operate with higher ESR (340 mOhm vs. 160 mOhm) and lower ripple current ratings (182 mA @ 120 Hz, 280 mA @ 100 kHz vs. 390 mA @ 120 Hz, 600 mA @ 100 kHz). Circuit designs must accommodate these electrical differences.

Q: What is the difference between EEE-FTJ471XAL and EEE-FTJ471XAP?

A: These parts are electrically identical with matching 160 mOhm ESR and ripple current specifications. The difference is packaging format: EEE-FTJ471XAL is supplied in Tape & Reel (TR) format, while EEE-FTJ471XAP is supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain Active product status.

Q: Why do EEE-FKJ471XSL and EEE-FKJ471XSP carry "Not For New Designs" status?

A: These parts are legacy products from the FKS series. While they remain electrically and mechanically compatible with the primary part, their Not For New Designs classification indicates that Panasonic recommends using Active status alternatives (FT or FN series) for new circuit development. Existing designs may continue using these parts for replacement purposes.

Q: Are all substitute parts halogen-free?

A: The EEE-FTJ471XAL, EEE-FTJ471XAP, EEE-FNJ471XUL, and EEE-FNJ471XUP are explicitly designated as halogen-free. The EEE-FKJ471XSL and EEE-FKJ471XSP do not carry halogen-free designation in the provided specifications. All parts are RoHS3 compliant.

Q: What is the impact of higher ESR in FN and FKS series substitutes?

A: The FN and FKS series parts operate at 340 mOhm ESR compared to 160 mOhm in the FT series. Higher ESR results in increased impedance and heat generation under ripple current conditions. Circuits designed for the lower ESR of the FT series must be evaluated to ensure the higher impedance does not degrade performance in filtering, voltage regulation, or noise suppression applications.

Q: Can packaging format differences affect circuit assembly?

A: Yes. EEE-FTJ471XAL uses Tape & Reel (TR) packaging, while EEE-FTJ471XAP uses Cut Tape (CT) & Digi-Reel® packaging. Assembly equipment and feeder compatibility must be verified. TR format is standard for high-volume automated assembly, while CT format is suitable for lower-volume or mixed-component runs.

Q: Are all parts suitable for automotive applications?

A: Yes. All listed parts carry AEC-Q200 qualification and are designated for automotive applications. This qualification ensures reliability and performance in automotive operating conditions and temperature ranges.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry this designation, meaning they do not require special dry storage or baking procedures prior to assembly.
