EEE-FTJ471XAV Equivalent & Substitute Parts

Part Overview

The EEE-FTJ471XAV is a 470 µF, 6.3 V aluminum electrolytic capacitor in SMD radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications and high-temperature reflow processes, with AEC-Q200 qualification and a 2000-hour lifetime at 105°C. The part is currently in active production status.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design requirements permit alternative electrical characteristics within acceptable tolerances. The EEE-FKJ471XSV series provides functional equivalence with differing electrical performance characteristics suitable for specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FTJ471XAV is determined by strict equivalence in the following parameters:

• Capacitance value: 470 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.248" Dia (6.30mm), Height 0.327" (8.30mm) (exact match required)
• Land size: 0.260" L x 0.260" W (6.60mm x 6.60mm) (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Surface Mount (exact match required)
• Compliance certifications: AEC-Q200, RoHS3 (exact match required)

The EEE-FKJ471XSV meets all substitution criteria. Variations in ESR and ripple current ratings reflect different internal construction within the same package envelope and do not affect PCB-level compatibility or mounting procedures.

Parameter Comparison

Engineering Selection Recommendations

The EEE-FTJ471XAV is the preferred selection for new designs due to its active production status and lower ESR characteristics. This part provides superior performance in ripple current handling and thermal efficiency.

The EEE-FKJ471XSV is a valid substitute for existing designs where the EEE-FTJ471XAV becomes unavailable. Both parts carry identical AEC-Q200 automotive qualification, RoHS3 compliance, and MSL-1 moisture sensitivity ratings. The substitute part is suitable for applications where the higher ESR and reduced ripple current ratings remain within circuit design margins.

No PCB redesign is required when substituting between these parts, as physical dimensions, land sizes, and mounting characteristics are identical. Component selection should be based on circuit-level ripple current requirements and thermal management considerations specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FKJ471XSV be used as a direct replacement for the EEE-FTJ471XAV on existing PCBs?

A: Yes. Both parts share identical physical dimensions (0.248" diameter, 0.327" height), land sizes (0.260" x 0.260"), and mounting type (Surface Mount). No PCB modifications are required for mechanical compatibility.

Q: What is the primary electrical difference between these two parts?

A: The EEE-FKJ471XSV has higher ESR (340 mOhm vs. 160 mOhm at 100 kHz) and lower ripple current ratings (182 mA at 120 Hz and 280 mA at 100 kHz, compared to 390 mA and 600 mA respectively). These differences reflect internal construction variations and do not affect basic capacitance or voltage rating equivalence.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-FTJ471XAV and EEE-FKJ471XSV carry AEC-Q200 qualification and are rated for automotive and high-temperature reflow applications across the -55°C to 105°C operating range.

Q: Why is the EEE-FKJ471XSV marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production status. For new product development, the EEE-FTJ471XAV (Active status) is the recommended choice. The EEE-FKJ471XSV remains available for legacy design support and supply continuity.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts have identical MSL-1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control measures are required during storage, handling, or assembly.

Q: Can circuit design proceed without considering the ESR difference?

A: ESR differences must be evaluated against specific circuit requirements. Applications with high ripple current demands or stringent thermal constraints should prioritize the EEE-FTJ471XAV. The EEE-FKJ471XSV is suitable where ripple current and thermal margins accommodate the higher ESR specification.
