Voltage rating must be equal to or greater than 10 V (higher voltage ratings provide design margin and are electrically compatible)
Tolerance must be ±20% or tighter
Ripple current capability must meet or exceed 670 mA @ 100 kHz

Mechanical Compatibility:

Package type must be Radial, Can - SMD
Physical dimensions (diameter 10.00mm, height ≤10.20mm) must fit existing PCB footprints
Surface mount land size 0.406" L x 0.406" W (10.30mm x 10.30mm) must match design layout

Reliability & Compliance:

AEC-Q200 automotive qualification required
RoHS compliance required
Moisture Sensitivity Level 1 (Unlimited) required

Performance Enhancement Criteria:

Lifetime at 105°C may be extended (1000 Hrs, 2000 Hrs, or 5000 Hrs) without design impact
Impedance may be reduced (lower impedance improves performance)
Operating temperature range may be extended (e.g., -55°C vs -40°C)
Product status upgrade from "Not For New Designs" to "Active" is preferred for long-term availability

Substitutes are grouped by voltage rating tier (10V, 16V, 25V, 35V) and series family (FC, FK, FP, FKS), with voltage-uprated parts serving as direct electrical substitutes.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage, Same Packaging): EEE-FC1A471P is the direct equivalent, differing only in packaging format (Cut Tape & Digi-Reel vs. Tape & Reel). Both carry "Not For New Designs" status and identical electrical specifications. Selection depends on production line packaging requirements.

Voltage-Uprated Substitutes (Same Series, Higher Voltage): EEE-FC1C471AP, EEE-FC1C471P, EEE-FC1E471AP, and EEE-FC1E471P are electrically compatible substitutes with 16 V and 25 V ratings respectively. These maintain the FC series characteristics (1000 Hrs @ 105°C, 150 mOhms impedance) while providing increased voltage margin. All retain "Not For New Designs" status.

Active Series Upgrades (FK Series - Enhanced Performance): EEE-FK1E471AP, EEE-FK1E471P, and EEE-FK1E471GP represent significant performance improvements:

Extended lifetime: 2000 Hrs or 5000 Hrs @ 105°C (vs. 1000 Hrs)
Reduced impedance: 80 mOhms (vs. 150 mOhms)
Increased ripple current: 850 mA @ 100 kHz (vs. 670 mA)
Extended operating temperature: -55°C to 105°C (vs. -40°C to 105°C)
Active product status ensures long-term availability
Height increases to 0.413" (10.50mm); verify PCB clearance

EEE-FK1E471GP offers maximum reliability with 5000 Hrs lifetime rating, suitable for mission-critical automotive applications.

Premium Performance Alternative (FP Series): EEE-FP1E471AP delivers the lowest impedance (60 mOhms) and highest ripple current capability (1.19 A @ 100 kHz). Active product status and 2000 Hrs lifetime make it suitable for high-ripple-current applications. Maintains original height (0.402"), simplifying PCB integration.

Higher Voltage Tier (35 V): EEE-FK1V471SP provides maximum voltage margin at 35 V with FK series performance benefits. "Not For New Designs" status limits long-term viability; consider only if voltage requirement exceeds 25 V.

Compliance & Availability: All substitutes maintain AEC-Q200 automotive qualification, RoHS compliance, and MSL 1 (Unlimited) moisture sensitivity. FK and FP series parts carry ROHS3 compliance. Active product status (FK and FP series) is preferred for designs requiring extended production life.

Frequently Asked Questions (FAQ)

Q: Can I substitute EEE-FC1A471AP with a higher voltage-rated part? A: Yes. Higher voltage ratings (16 V, 25 V, 35 V) are electrically compatible and provide design margin. The capacitor will function correctly in circuits designed for 10 V operation. Verify that PCB layout and thermal management accommodate any dimensional changes (height may increase from 0.402" to 0.413").

Q: What is the difference between EEE-FC1A471AP and EEE-FK1E471AP? A: Both are 470 µF, 25 V capacitors with identical footprints. Key differences: EEE-FK1E471AP offers 2000 Hrs lifetime (vs. 1000 Hrs), 80 mOhms impedance (vs. 150 mOhms), 850 mA ripple current (vs. 670 mA), extended temperature range (-55°C to 105°C vs. -40°C to 105°C), and Active product status. Height increases 0.011" (0.30mm).

Q: Why should I choose an Active product status part over "Not For New Designs"? A: Active parts ensure long-term manufacturing availability, stable pricing, and continued supplier support. "Not For New Designs" parts may face discontinuation, supply constraints, or price volatility. For new designs or production runs extending beyond 2-3 years, Active status parts (FK and FP series) are strongly preferred.

Q: Is EEE-FP1E471AP compatible with my existing PCB layout? A: EEE-FP1E471AP maintains the original height (0.402") and land size (0.406" L x 0.406" W), ensuring direct PCB compatibility. It differs from FK series parts, which are 0.011" taller (0.413"). Verify clearance above the capacitor before substitution.

Q: Can I use EEE-FK1E471GP instead of EEE-FK1E471AP? A: Yes. Both are identical except for lifetime rating: EEE-FK1E471GP is rated 5000 Hrs @ 105°C (vs. 2000 Hrs). This upgrade improves reliability without affecting electrical performance or physical dimensions. Use EEE-FK1E471GP for applications requiring maximum thermal endurance.

Q: What packaging options are available? A: EEE-FC1A471AP is supplied in Tape & Reel (TR). Equivalent EEE-FC1A471P uses Cut Tape & Digi-Reel packaging. FK and FP series are available in Tape & Reel. Confirm packaging compatibility with your assembly equipment before ordering.

Q: Are all substitutes AEC-Q200 qualified? A: Yes. All listed substitutes carry AEC-Q200 automotive qualification and RoHS compliance. FK and FP series additionally meet ROHS3 requirements. MSL 1 (Unlimited) moisture sensitivity applies to all parts, requiring no special storage precautions.

Q: Which substitute offers the best overall performance? A: EEE-FK1E471GP combines maximum lifetime (5000 Hrs), lowest impedance (80 mOhms), highest ripple current (850 mA), extended temperature range (-55°C to 105°C), and Active product status. It is the optimal choice for demanding automotive applications where reliability and performance are critical.
