ECE-V1CA331UP Equivalent & Substitute Parts

Part Overview

The ECE-V1CA331UP is a 330 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This part operates across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Compatibility Requirements:

Capacitance: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Mounting Type: Surface Mount (exact match required)
Physical Size: 0.315" Dia (8.00mm) (exact match required)
Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm) (exact match required)

Voltage Rating Substitution Logic: Parts rated at 16 V or higher voltage are acceptable substitutes. Parts with lower voltage ratings are not acceptable.

Thermal and Lifetime Considerations: Substitute parts may have extended operating temperature ranges and longer lifetimes at elevated temperatures. These represent improvements over the original specification and do not restrict substitution.

Product Status: Active parts from current product lines are preferred over obsolete designations. Parts marked "Not For New Designs" may be used for legacy system maintenance.

Engineering Selection Recommendations

For Direct Replacement (16 V Rating):

EEE-FP1C331AP is the primary substitute for ECE-V1CA331UP. Both maintain 16 V voltage rating and identical physical dimensions (0.315" diameter, 0.402" height). EEE-FP1C331AP is active, ROHS3 compliant, and extends operating temperature to -55°C ~ 105°C with 2000 hour lifetime at 105°C.

EEE-FK1C331AP and EEE-FK1C331GP are alternative 16 V substitutes with slightly increased height (0.413" vs 0.402"). Both are active and ROHS3 compliant. EEE-FK1C331GP offers extended 5000 hour lifetime at 105°C.

For Voltage Margin Applications (25 V Rating):

EEE-FK1E331P and EEE-FP1E331AP provide 25 V rating in the same physical footprint. Both are active and ROHS3 compliant. EEE-FK1E331P offers higher inventory availability (83,030 pcs). EEE-FP1E331AP maintains original height dimension (0.402").

For Extended Temperature Range (35 V Rating):

EEE-FT1V331AP provides 35 V rating with extended operating range (-55°C ~ 105°C) and is active with ROHS3 compliance. This part is suitable for applications requiring maximum voltage margin and thermal performance.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, addressing regulatory requirements not met by the obsolete ECE-V1CA331UP.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C331AP replace ECE-V1CA331UP directly on the PCB?

A: EEE-FK1C331AP is electrically compatible and uses identical land size (0.327" x 0.327"). The height difference (0.413" vs 0.402") is 0.011" and must be evaluated for mechanical clearance in the specific application. The part is otherwise a direct substitute.

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

A: Both series meet the same electrical specifications for 330 µF 16 V and 25 V ratings. EEE-FP series maintains the original 0.402" height, while EEE-FK series is 0.413" tall. EEE-FP is preferred when height clearance is critical.

Q: Is EEE-1CA331UP suitable for new designs?

A: EEE-1CA331UP is marked "Not For New Designs" and should only be used for legacy system maintenance. For new designs, select from active parts: EEE-FK1C331AP, EEE-FK1C331GP, EEE-FK1C331P, EEE-FK1E331AP, EEE-FK1E331GP, EEE-FK1E331P, EEE-FT1V331AP, EEE-FP1C331AP, or EEE-FP1E331AP.

Q: Can I use a 25 V rated part instead of 16 V?

A: Yes. A 25 V rated capacitor is a valid substitute for a 16 V application. The higher voltage rating provides additional safety margin. EEE-FK1E331P, EEE-FK1E331AP, EEE-FK1E331GP, and EEE-FP1E331AP are all acceptable 25 V alternatives.

Q: What is the advantage of EEE-FK1C331GP over EEE-FK1C331AP?

A: EEE-FK1C331GP extends the rated lifetime to 5000 hours at 105°C, compared to 2000 hours for EEE-FK1C331AP. Both maintain identical electrical specifications and physical dimensions. Select EEE-FK1C331GP for applications requiring extended operational life at elevated temperatures.

Q: Are all substitute parts AEC-Q200 rated?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification. This certification is not present on the obsolete ECE-V1CA331UP.

Q: What packaging options are available?

A: EEE-1CA331UP, EEE-FK series, and EEE-FT1V331AP are supplied in Tape & Reel (TR). EEE-FP1C331AP is available in Cut Tape (CT) & Digi-Reel®. Select based on assembly process requirements.
