Key Parameters

Substitute Part Grouping Explanation

Substitution for the UWS0J331MCL1GS is determined by strict electrical and mechanical compatibility:

Electrical Parameters (Must Match):

• Capacitance: 330 µF
• Voltage Rating: 6.3 V
• Tolerance: ±20%
• Operating Temperature Range: -40°C ~ 85°C minimum

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - SMD
• Mounting Type: Surface Mount
• Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm)

Acceptable Variations:

• Height: Parts with height up to 0.256" (6.50mm) are compatible with the same PCB footprint
• Ripple Current: Rated values may vary; parts meeting or exceeding the original specification are acceptable
• Lifetime: Parts rated for 2000 Hrs @ 85°C or higher temperature ratings are acceptable
• Packaging Format: Cut Tape (CT) and Tape & Reel (TR) are both acceptable for manufacturing

Substitutes are grouped into three categories: Direct equivalents (same series, same dimensions), similar parts (same electrical specs, different dimensions within compatibility), and upgraded parts (enhanced specifications with extended temperature or automotive ratings).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Footprint): UUR0J331MCL1GS is the primary direct equivalent from Nichicon. It maintains identical electrical specifications and the same 8.30mm x 8.30mm land size. The height difference of 0.012" (0.30mm) is within acceptable PCB assembly tolerances. This part is available in higher quantities (117,400 pcs) and is RoHS3 compliant.

Upgraded Alternative (Enhanced Performance): EEE-HBJ331UAP from Panasonic is an active product with identical footprint and dimensions to the original part. It offers extended temperature operation (-40°C ~ 105°C vs. -40°C ~ 85°C), higher ripple current capability at 10 kHz (306 mA vs. 247 mA), and AEC-Q200 automotive qualification. This part is suitable for applications requiring higher reliability and temperature margin.

Smaller Footprint Alternatives (Different Land Size): UUR0J331MCL6GS, EMVA6R3ADA331MF80G, EEE-0JA331XAP, and EEE-0JA331XP all use a 6.60mm x 6.60mm land size, requiring PCB redesign. These are suitable only if board layout permits the smaller footprint. EEE-0JA331XAP and EEE-0JA331XP offer higher ripple current ratings (319.6 mA @ 10 kHz) and AEC-Q200 compliance.

Compatibility Constraints: Parts with different land sizes (6.60mm x 6.60mm) cannot be used as direct drop-in replacements without PCB modification. AVE337M06X16T-F has lower ripple current ratings and should be evaluated for specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can UUR0J331MCL1GS replace UWS0J331MCL1GS directly on the PCB? A: Yes. Both parts share identical electrical specifications, the same 8.30mm x 8.30mm land size, and compatible dimensions. The 0.012" height difference is within standard PCB assembly tolerances.

Q: What is the difference between parts with 8.30mm and 6.60mm land sizes? A: Land size determines the PCB footprint. Parts with 6.60mm x 6.60mm land sizes require PCB redesign and cannot be used as direct substitutes without layout modification. The 8.30mm x 8.30mm land size matches the original UWS0J331MCL1GS footprint.

Q: Is EEE-HBJ331UAP suitable for the same application? A: Yes, with enhanced performance. It has identical footprint and dimensions, matching electrical specifications, and offers extended temperature operation to 105°C. It is an active product with AEC-Q200 automotive qualification, making it suitable for long-term production.

Q: Why are some parts marked "Not For New Designs"? A: Parts with this status are end-of-life or transitioning out of production. While electrically compatible, they should not be selected for new designs. EEE-HBJ331UAP is the recommended alternative for new designs.

Q: What is the significance of RoHS3 compliance? A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. UUR0J331MCL1GS and EEE-HBJ331UAP are both RoHS3 compliant, ensuring regulatory compliance for EU markets.

Q: Can I use a part with lower ripple current rating? A: No. Ripple current rating must meet or exceed the circuit requirement. Parts with lower ratings (such as AVE337M06X16T-F at 111.2 mA @ 10 kHz) are not suitable if the original design requires 247 mA @ 10 kHz.

Q: What packaging formats are available? A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) formats. Both are suitable for manufacturing; selection depends on production equipment and volume requirements.
