Substitute Part Grouping Explanation

Substitute parts for the UUR1E331MNL1GS are categorized based on the following substitution criteria:

Direct Substitution Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.394" Dia (10.00mm) with 0.413" (10.50mm) height (exact match required)
• Surface Mount Land Size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• MSL: 1 (Unlimited) (exact match required)

Acceptable Variations:

• Lifetime @ Temperature: 2000 Hrs @ 85°C or higher temperature rating (e.g., 2000 Hrs @ 105°C)
• Operating Temperature Range: -40°C ~ 85°C or wider range (e.g., -55°C ~ 105°C)
• Ripple Current: Values may vary within acceptable performance envelope
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® are interchangeable for procurement
• Product Status: Active or Obsolete parts are acceptable; Last Time Buy parts are acceptable

Upgrade Substitution Parameters:

• Voltage Rating: 35 V (higher voltage rating provides design margin)
• All other parameters remain identical to main part specifications

Similar Substitution Parameters:

• Physical Dimensions: 0.315" Dia (8.00mm) with 0.413" (10.50mm) height and 0.327" L x 0.327" W (8.30mm x 8.30mm) land size (smaller footprint, same electrical performance)
• All other parameters remain identical to main part specifications

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - MFR Recommended Substitute: UUX1E331MNL1GS (Nichicon) is the manufacturer-recommended direct substitute. This part maintains identical electrical and mechanical specifications while offering an extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C). Product status is Active, ensuring long-term availability.

Active Product Alternatives: EDK337M025A9PAA (KEMET) and VE-331M1ETR-1010S (SURGE) are parametrically equivalent alternatives with Active product status. Both maintain identical capacitance, voltage, tolerance, and physical dimensions as the main part. These options provide supply chain flexibility.

Upgrade Option: UUR1V331MNL1GS (Nichicon) provides a 35 V voltage rating upgrade while maintaining all other specifications. This option is suitable for applications requiring additional voltage margin.

Smaller Footprint Alternatives: UUR1E331MNL6GS (Nichicon), EEE-1EA331UAP (Panasonic), and EMVA250ARA331MHA0G (Chemi-Con) offer reduced physical dimensions (0.315" Dia / 8.00mm) with corresponding smaller land sizes (0.327" x 0.327" / 8.30mm x 8.30mm). These are suitable for space-constrained applications with identical electrical performance.

Legacy Design Compatibility: EEE-1EA331AP and EEE-1EA331P (Panasonic) are marked as Not For New Designs but remain available for legacy system maintenance. Both carry AEC-Q200 automotive qualification and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can UUX1E331MNL1GS replace UUR1E331MNL1GS directly? A: Yes. UUX1E331MNL1GS is the manufacturer-recommended substitute with identical electrical and mechanical specifications. The extended operating temperature range and higher temperature lifetime rating provide additional design margin.

Q: What is the difference between the 10.00mm and 8.00mm diameter versions? A: The 8.00mm diameter versions (UUR1E331MNL6GS, EEE-1EA331UAP, EMVA250ARA331MHA0G) provide identical electrical performance with reduced physical footprint and smaller PCB land size. Selection depends on available board space.

Q: Is UUR1V331MNL1GS (35V) compatible with a 25V circuit design? A: UUR1V331MNL1GS is a voltage upgrade option. The higher 35 V rating is backward compatible with 25 V circuit designs and provides additional voltage margin. Physical dimensions and electrical performance remain identical.

Q: What does "Not For New Designs" mean for Panasonic parts? A: Parts marked "Not For New Designs" are available for legacy system maintenance and repair but should not be selected for new product development. Active alternatives such as EDK337M025A9PAA or VE-331M1ETR-1010S are recommended for new designs.

Q: Are there differences in ripple current ratings between substitutes? A: Ripple current values vary between manufacturers and part numbers. All listed substitutes meet the 330 µF, 25 V, ±20% tolerance specification. Ripple current performance is application-dependent; verify specific values against circuit requirements.

Q: What packaging formats are available? A: Substitutes are available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats. These are procurement packaging options and do not affect component performance or PCB mounting.

Q: Are all substitutes RoHS3 compliant? A: All listed substitutes meet RoHS compliance requirements. Most are ROHS3 compliant; Panasonic parts EEE-1EA331AP and EEE-1EA331P carry standard RoHS compliance. Verify specific compliance requirements for your application.
