Surface Mount Land Size: 0.327" L × 0.327" W (8.30mm × 8.30mm)

Allowable Variations:

Voltage Rating: May be equal or higher than 16 V (16 V, 25 V, or 35 V acceptable)
Manufacturer: Different manufacturers permitted if all critical parameters match
Impedance: Variations permitted within electrical performance envelope

Engineering Selection Recommendations

Direct Replacement (Same Voltage, Active Status): EEE-FK1C331GP is the primary direct replacement for the obsolete EEV-FK1C331GP. Both are Panasonic FK series parts with identical electrical specifications and physical dimensions. EEE-FK1C331GP carries ROHS3 compliance and active product status, making it the preferred choice for new designs and production continuity.

Parametric Equivalents (16 V Rating, Active Status): EMZL160ARA331MHA0G (Chemi-Con), EXV337M016S9MAA (KEMET), UCD1C331MNL1GS (Nichicon), and UUD1C331MNL1GS (Nichicon) are all qualified alternatives meeting the 330 µF, 16 V specification with AEC-Q200 automotive rating and ROHS3 compliance. These parts maintain identical physical footprints and electrical performance within the specified parameter envelope. UUD1C331MNL1GS exhibits slightly higher impedance (170 mOhms) and lower ripple current capability (450 mA @ 100 kHz) compared to the main part.

Voltage-Upgraded Alternatives (Higher Voltage Rating, Active Status): EEE-FK1E331GP (25 V) and EEE-FT1V331GP (35 V) are Panasonic alternatives with elevated voltage ratings. These parts are electrically and mechanically compatible with the original specification and provide additional voltage margin for circuit protection. EEE-FT1V331GP offers improved ripple current performance (850 mA @ 100 kHz) and lower impedance (80 mOhms). 25TLV330M8X10.5 (Rubycon, 25 V) provides an alternative manufacturer option at the intermediate voltage level.

Compliance and Availability: All recommended substitutes carry AEC-Q200 automotive qualification and ROHS3 compliance. EEE-FK1C331GP and UCD1C331MNL1GS offer the highest inventory availability (1599 and 24400 units respectively), supporting production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A 25 V or 35 V rated capacitor is electrically compatible with a 16 V application, provided all other parameters (capacitance, tolerance, temperature rating, physical dimensions, and AEC-Q200 qualification) remain unchanged. Higher voltage ratings provide additional safety margin in the circuit.

Q: Are all substitute parts physically identical? A: Yes. All listed substitutes maintain the same physical dimensions (0.315" diameter, 0.413" height) and surface mount land size (0.327" × 0.327"), ensuring direct PCB compatibility without layout modifications.

Q: What is the difference between the Panasonic FK and FT series? A: Both FK and FT series are Panasonic aluminum electrolytic capacitors meeting AEC-Q200 automotive standards. The FT series (represented by EEE-FT1V331GP) offers improved electrical performance with lower impedance and higher ripple current capability at higher voltage ratings.

Q: Why is the original EEV-FK1C331GP obsolete? A: The EEV-FK1C331GP has been superseded by the EEE-FK1C331GP, which maintains identical electrical and mechanical specifications while offering improved compliance status (ROHS3) and active product support.

Q: Can I substitute parts from different manufacturers? A: Yes. EMZL160ARA331MHA0G (Chemi-Con), EXV337M016S9MAA (KEMET), and Nichicon parts (UCD1C331MNL1GS, UUD1C331MNL1GS) are all qualified parametric equivalents with identical capacitance, voltage, tolerance, and physical specifications. All carry AEC-Q200 automotive qualification.

Q: What is the significance of AEC-Q200 rating? A: AEC-Q200 is the automotive electronics council qualification standard for capacitors. All listed parts meet this requirement, confirming suitability for automotive applications with specified reliability and performance standards.

Q: Does packaging format affect substitution? A: The main part is supplied in standard packaging. Substitute parts may be available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Packaging format does not affect electrical or mechanical compatibility; selection depends on assembly process requirements.
