Substitute Part Grouping Explanation
Substitution logic is based on the following criteria:
Direct Electrical Equivalents match all critical parameters: 330 µF capacitance, ±20% tolerance, 25 V rating, 5000 hour lifetime at 105°C, and compatible mechanical dimensions (10.00 mm diameter, 10.30 mm × 10.30 mm land size).
Upgraded Voltage Rating parts maintain identical capacitance, tolerance, and lifetime but increase voltage rating to 35 V, providing enhanced margin in applications where voltage stress is a design consideration.
Reduced Footprint Alternatives maintain electrical specifications but use smaller case diameters (8.00 mm) with adjusted land sizes (8.30 mm × 8.30 mm), suitable for space-constrained layouts.
Reduced Lifetime Variants maintain the 10.00 mm form factor and electrical ratings but operate at lower lifetime ratings (1000 or 2000 hours at 105°C), appropriate for non-critical applications.
Cross-Manufacturer Equivalents from Cornell Dubilier Electronics and Panasonic provide identical or superior electrical performance with AEC-Q200 automotive qualification where applicable.

Engineering Selection Recommendations
Direct Replacement (Same Form Factor & Lifetime)
UUA1E331MNL1GS is the primary parametric equivalent, maintaining the 10.00 mm diameter, 10.00 mm height, and 5000 hour lifetime specification. Both parts are active and ROHS3 compliant with unlimited moisture sensitivity rating.
Upgraded Voltage Margin
UUD1V331MNL1GS provides 35 V rating in the same 10.00 mm form factor with AEC-Q200 automotive qualification. Height increases to 10.50 mm. This option is suitable when voltage stress margin is required.
Reduced Footprint with Maintained Lifetime
EEE-FK1E331GP (Panasonic) and UUD1E331MNL1GS (Nichicon) both deliver 5000 hour lifetime in 8.00 mm diameter packages. Both carry AEC-Q200 qualification. Land size reduces to 8.30 mm × 8.30 mm, enabling compact board layouts.
Cost-Optimized Alternatives
UWG1E331MNL1GS and AFC337M25G24T-F maintain the 10.00 mm form factor with reduced 1000 hour lifetime. Both are AEC-Q200 qualified. AFC337M25G24T-F is marked "Not For New Designs" and should be avoided for new development.
General Purpose Applications
UCL1E331MNL1GS offers 2000 hour lifetime in 8.00 mm form factor without automotive qualification, suitable for non-critical general purpose applications requiring space efficiency.
Frequently Asked Questions (FAQ)
Q: Can UUA1E331MNL1GS directly replace UWD1E331MCL1GS on the PCB?
A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), case diameter (10.00 mm), height (10.00 mm), and land size (10.30 mm × 10.30 mm). No PCB layout modification is required.
Q: What is the advantage of UUD1V331MNL1GS over the original part?
A: UUD1V331MNL1GS increases voltage rating from 25 V to 35 V while maintaining all other specifications. This provides additional voltage stress margin in applications subject to transient overvoltage. Height increases to 10.50 mm; verify clearance in your assembly.
Q: Can I use an 8.00 mm diameter part as a substitute?
A: Yes, if your PCB layout accommodates the smaller 8.30 mm × 8.30 mm land size. Parts such as EEE-FK1E331GP, UCD1E331MNL1GS, and UUD1E331MNL1GS are electrically compatible. Verify mechanical clearance and thermal performance, as smaller packages may have different thermal characteristics.
Q: What is the difference between 1000 hour and 5000 hour lifetime ratings?
A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. 5000 hour parts are suitable for long-life applications; 1000 hour parts are appropriate for cost-sensitive, non-critical applications with shorter service life requirements.
Q: Are cross-manufacturer parts (Cornell Dubilier, Panasonic) direct substitutes?
A: Electrical parameters are equivalent, but mechanical dimensions and certifications differ. AFK337M25F24T-F and EEE-FK1E331AP/GP use 8.00 mm form factors. AFC337M25G24T-F is marked "Not For New Designs" and should not be selected for new projects. Panasonic EEE-FK series parts carry AEC-Q200 automotive qualification and are active products.
Q: Does RoHS3 compliance apply to all substitute parts?
A: Yes. All listed substitute parts are ROHS3 compliant. Moisture sensitivity level is 1 (Unlimited) for all parts except UCD1E331MNL1GS, which is not applicable.
Q: Which substitute offers the best ripple current performance?
A: UCL1E331MNL1GS delivers the highest ripple current capacity at 425 mA @ 120 Hz and 850 mA @ 100 kHz, though with reduced 2000 hour lifetime. For 5000 hour lifetime, UUA1E331MNL1GS provides 450 mA @ 120 Hz.
