EEU-FC1A472B Equivalent & Substitute Parts

Part Overview

The EEU-FC1A472B is a 4700 µF, 10 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This capacitor is rated for 5000 hours at 105°C and is designed for automotive applications with AEC-Q200 compliance. The part is currently active and available in Tape & Box packaging.

Substitute parts become necessary when the primary part number is unavailable, when alternative packaging formats are required, or when design flexibility allows for functionally equivalent alternatives from other manufacturers while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

EEU-FC1A472 (Direct Panasonic Substitute): This part is the preferred direct substitute for EEU-FC1A472B. Both are manufactured by Panasonic, share identical electrical specifications, and maintain AEC-Q200 automotive compliance. The only difference is packaging format (Bulk versus Tape & Box) and a minor height variation of 0.079" (2.00mm). This part is suitable for new designs and carries Active product status.

UPJ1A472MHD (Nichicon Alternative): This part meets all core electrical and mechanical parameters but carries a "Not For New Designs" product status. The height is 0.236" (6.00mm) greater than the main part, and impedance is 6 mOhms higher. This part is suitable only for legacy designs or replacement applications where the increased height does not create PCB layout conflicts.

UPS1A472MHD (Nichicon Alternative): This part carries a "Not For New Designs" product status and has a reduced lifetime rating of 3000 hours at 105°C compared to the 5000-hour specification of the main part. Additionally, impedance is 16 mOhms higher and ripple current ratings are significantly lower. This part is suitable only for applications with reduced thermal stress or legacy designs where the lower performance specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1A472 be used as a direct replacement for EEU-FC1A472B?

A: Yes. Both parts are manufactured by Panasonic with identical electrical specifications (4700 µF, 10 V, ±20%, 5000 Hrs @ 105°C). The difference is packaging format and a 2.00mm height variation. Verify PCB clearance for the 25.00mm seated height of EEU-FC1A472.

Q: Are the Nichicon parts (UPJ1A472MHD and UPS1A472MHD) suitable for new automotive designs?

A: No. Both Nichicon parts carry "Not For New Designs" product status. They are suitable only for legacy designs, replacement applications, or non-automotive general-purpose applications where the reduced specifications are acceptable.

Q: What is the impact of the higher impedance in substitute parts?

A: UPJ1A472MHD has 28 mOhms impedance (6 mOhms higher than the main part), and UPS1A472MHD has 38 mOhms impedance (16 mOhms higher). Higher impedance increases voltage ripple and heat generation under AC ripple current conditions. Verify that the application's ripple current and thermal requirements are compatible with the substitute part's impedance specification.

Q: Does the reduced lifetime of UPS1A472MHD affect substitution eligibility?

A: UPS1A472MHD is rated for 3000 hours at 105°C versus 5000 hours for the main part. This part is suitable only for applications with lower thermal stress or shorter service life requirements. For automotive applications requiring the full 5000-hour specification, this part is not appropriate.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (EEU-FC1A472, UPJ1A472MHD, and UPS1A472MHD) are ROHS3 compliant and meet REACH requirements.

Q: What is the significance of the height differences between parts?

A: EEU-FC1A472B has a seated height of 27.00mm, EEU-FC1A472 is 25.00mm, UPJ1A472MHD is 33.00mm, and UPS1A472MHD is 27.00mm. Verify PCB layout and component clearance, particularly for confined spaces or designs with height restrictions.
