EEE-FTA331XAV Equivalent & Substitute Parts

Part Overview

The EEE-FTA331XAV is a 330 µF, 10 V aluminum electrolytic capacitor in surface mount 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 may be required due to supply constraints, design revisions, or specific performance requirements in ripple current handling and equivalent series resistance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FTA331XAV is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD with identical case dimensions (0.248" Dia × 0.327" H)
• Land Size: 0.260" L × 0.260" W (exact match required for PCB compatibility)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Lifetime Rating: 2000 Hrs @ 105°C (minimum requirement)
• Polarization: Polar (exact match required)
• Compliance: AEC-Q200, ROHS3, REACH Unaffected

The EEE-FKA331XSV meets all mandatory substitution criteria. Variations in ESR and ripple current ratings do not disqualify a part from substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Selection: EEE-FTA331XAV is the recommended choice for new designs. This part carries Active product status and represents the current production standard from Panasonic Electronic Components.

Substitute Selection: EEE-FKA331XSV is a valid substitute when the primary part is unavailable. Both parts maintain identical electrical specifications for capacitance, voltage rating, tolerance, and temperature range. Both are AEC-Q200 qualified and ROHS3 compliant, meeting automotive and high-temperature reflow requirements.

Critical Consideration: The EEE-FKA331XSV carries a "Not For New Designs" status. While it meets all mandatory substitution parameters, its use should be limited to replacement or legacy applications where supply of the EEE-FTA331XAV is constrained. The higher ESR (340 mOhm vs. 160 mOhm) and reduced ripple current ratings of the substitute part may impact performance in applications with stringent power delivery or thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FKA331XSV be used as a direct replacement for EEE-FTA331XAV on existing PCBs?

A: Yes. Both parts share identical case dimensions (0.248" Dia × 0.327" H) and land size (0.260" L × 0.260" W), ensuring mechanical and electrical compatibility on the same PCB layout without modification.

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

A: The main differences are ESR and ripple current ratings. The EEE-FTA331XAV has lower ESR (160 mOhm) and higher ripple current capacity (600 mA @ 100 kHz) compared to the EEE-FKA331XSV (340 mOhm, 280 mA @ 100 kHz). Both parts meet the same 2000-hour lifetime and temperature specifications.

Q: Why is the EEE-FKA331XSV marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. Panasonic recommends using the EEE-FTA331XAV for new product development to ensure long-term supply availability and access to the latest manufacturing improvements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-FTA331XAV and EEE-FKA331XSV carry AEC-Q200 qualification and are rated for automotive and high-temperature reflow applications across the -55°C to 105°C operating range.

Q: What compliance certifications do these parts hold?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain MSL Rating 1 (Unlimited moisture sensitivity level).
