Engineering Selection Recommendations

Direct Manufacturer Substitutes (Panasonic FT Series):

EEE-FT1E471GP is the preferred direct substitute when extended operational lifetime is required. This part maintains identical electrical specifications and package dimensions while providing 5000 hours lifetime at 105°C compared to 2000 hours for the primary part. Both parts are active in production and carry full AEC-Q200 automotive qualification and RoHS3 compliance.

EEE-FT1E471AL is functionally equivalent to the primary part with identical electrical and mechanical specifications. This variant is designated halogen-free and is active in production, suitable for applications with halogen-free material requirements.

Parametric Equivalents (Panasonic FN/FK Series):

EEE-FN1E471UL and EEE-FN1E471UP are active parametric equivalents with identical capacitance, voltage, tolerance, and package dimensions. These parts feature 160 mOhm ESR at 100 kHz and reduced ripple current specifications (390 mA @ 120 Hz, 600 mA @ 100 kHz) compared to the primary part. Both are halogen-free and maintain AEC-Q200 qualification. Selection between these variants depends on halogen-free material requirements.

EEE-FK1E471SL is a halogen-free parametric equivalent with identical core specifications. This part carries "Not For New Designs" status and should be used only when existing inventory must be consumed or when legacy design compatibility is required.

Alternative Manufacturer Substitutes:

25TPV470M8X10.5 (Rubycon TPV series) provides identical electrical specifications and package dimensions with 80 mOhm ESR. This part is active in production with full AEC-Q200 and RoHS3 compliance.

EMZR250ARA471MHA0G and EMZS250ARA471MHA0G (Chemi-Con Alchip™ series) maintain identical electrical and mechanical specifications with 80 mOhm ESR and 2000 hour lifetime. Both are active in production with AEC-Q200 qualification and RoHS3 compliance.

UCM1E471MNL1GS (Nichicon UCM series) is functionally equivalent with 80 mOhm impedance specification. This part is active in production with AEC-Q200 qualification. Note: REACH Status is listed as "REACH Affected" for this part.

Similar Substitute (Different Package Footprint):

AFK477M25G24T-F (Cornell Dubilier Electronics AFK series) maintains identical electrical specifications and height but features a larger diameter (0.394" vs. 0.315") and different land size (0.406" L x 0.473" W vs. 0.327" L x 0.327" W). This part is suitable only when PCB layout accommodates the larger footprint. It is active in production with AEC-Q200 qualification and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute EEE-FT1E471AP with EEE-FT1E471GP?

A: Yes. EEE-FT1E471GP is a direct substitute with identical electrical and mechanical specifications. The primary difference is extended lifetime (5000 hours vs. 2000 hours at 105°C). Both parts are active in production with full AEC-Q200 automotive qualification and RoHS3 compliance. No PCB layout changes are required.

Q: What is the difference between the FT and FN series?

A: Both series maintain identical capacitance (470 µF), voltage (25 V), tolerance (±20%), and package dimensions. The FN series features 160 mOhm ESR at 100 kHz compared to 80 mOhm for the FT series, resulting in lower ripple current ratings (390 mA @ 120 Hz vs. 552.5 mA). The FN series is designated halogen-free. Selection depends on ripple current requirements and material compliance mandates.

Q: Can I use EEE-FK1E471SL as a substitute?

A: EEE-FK1E471SL is a parametric equivalent with identical core specifications but carries "Not For New Designs" status. Use this part only when consuming existing inventory or maintaining legacy designs. For new designs, select EEE-FN1E471UL or EEE-FN1E471UP instead.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and are suitable for automotive applications. All parts also maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Can I use AFK477M25G24T-F as a direct substitute?

A: AFK477M25G24T-F is electrically equivalent but has a different package footprint. The diameter is 0.394" (10.00 mm) versus 0.315" (8.00 mm) for the primary part, and the land size is 0.406" L x 0.473" W versus 0.327" L x 0.327" W. This part is suitable only if your PCB layout accommodates the larger footprint. No electrical redesign is required.

Q: What is the difference between EMZR250ARA471MHA0G and EMZS250ARA471MHA0G?

A: Both Chemi-Con Alchip™ parts maintain identical electrical specifications (470 µF, 25 V, 80 mOhm ESR, 2000 hour lifetime) and package dimensions. The primary difference is the series designation (MZR vs. MZS). Both are active in production with full AEC-Q200 qualification and RoHS3 compliance. Selection between these variants depends on supply availability and design documentation requirements.

Q: Does UCM1E471MNL1GS have any compliance restrictions?

A: UCM1E471MNL1GS is functionally equivalent with identical electrical and mechanical specifications. However, this part is listed with "REACH Status: REACH Affected" compared to "REACH Unaffected" for other substitutes. Verify REACH compliance requirements for your specific application before selection.

Q: Can I substitute based on ripple current alone?

A: No. Ripple current is a secondary specification. Primary substitution criteria include exact matching of capacitance (470 µF), voltage (25 V), tolerance (±20%), package dimensions, and operating temperature range (-55°C to 105°C). ESR and ripple current variations are acceptable within the parametric equivalent categories defined in this document.
