Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FP1E471AV is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (470 µF), voltage rating (25 V), and tolerance (±20%) must be identical. Lifetime rating (2000 Hrs @ 105°C) and operating temperature range (-55°C ~ 105°C) must match or exceed the main part specifications.

Mechanical Parameters: Package type (Radial, Can - SMD), case diameter (10.00 mm), height (10.80 mm maximum), and land size (10.30 mm x 10.30 mm) must be identical to ensure PCB compatibility without redesign.

Compliance & Certifications: AEC-Q200 rating, RoHS3 compliance, and MSL Level 1 classification must be maintained.

The EEE-FK1E471AV meets all substitution criteria. While ESR and ripple current specifications differ from the main part, these variations remain within acceptable ranges for the 470 µF, 25 V aluminum electrolytic capacitor category and do not compromise functional equivalence in automotive and high temperature reflow applications.

Engineering Selection Recommendations

Both the EEE-FP1E471AV and EEE-FK1E471AV are active production parts manufactured by Panasonic Electronic Components with identical AEC-Q200 automotive certification and RoHS3 compliance. Both parts maintain MSL Level 1 classification, indicating unlimited shelf life under standard storage conditions.

The EEE-FK1E471AV (FK series) is a direct parametric equivalent suitable for applications where the main part (FP series) is unavailable. Both parts share identical electrical ratings (470 µF, 25 V, ±20% tolerance), identical mechanical dimensions, and identical thermal specifications (2000 Hrs @ 105°C, -55°C ~ 105°C operating range).

Selection between these parts should be based on availability and inventory status. The EEE-FK1E471AV currently has 1728 units in stock compared to 1395 units for the EEE-FP1E471AV.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1E471AV replace the EEE-FP1E471AV without PCB redesign?

A: Yes. Both parts have identical case dimensions (10.00 mm diameter, 10.80 mm height) and land size (10.30 mm x 10.30 mm). No PCB layout modifications are required.

Q: What is the difference between the FP and FK series?

A: Both are Panasonic anti-vibration aluminum electrolytic capacitors in the same package. The FK series (EEE-FK1E471AV) has a higher ESR specification (80 mOhm @ 100 kHz) compared to the FP series (60 mOhm @ 100 kHz). Both meet the same automotive and thermal requirements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-FP1E471AV and EEE-FK1E471AV carry AEC-Q200 certification and are rated for automotive and high temperature reflow applications.

Q: What does MSL Level 1 mean for these capacitors?

A: MSL Level 1 indicates unlimited shelf life. These parts do not require special moisture control during storage or handling, provided standard storage conditions are maintained.

Q: Can these parts be used interchangeably in high ripple current applications?

A: The EEE-FP1E471AV has higher ripple current ratings (1.19 A @ 100 kHz) compared to the EEE-FK1E471AV (850 mA @ 100 kHz). Application-specific ripple current requirements should be evaluated before substitution.
