• Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage Rating: 6.3 V (main part) to 10 V, 16 V, or 25 V (substitutes)
• Lifetime @ Temperature: 7000 Hrs or 8000 Hrs @ 105°C
• Operating Temperature Range: -25°C ~ 105°C or -40°C ~ 105°C
• Manufacturer: Nichicon or Rubycon
• Series designation: UCB, UCW, or TRV

All substitute parts maintain identical capacitance, tolerance, and physical footprint compatibility while offering enhanced voltage ratings or extended thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Nichicon UCW1E331MNL1GS (25 V Rating): This substitute provides higher voltage rating within the same Nichicon product family. Both main part and substitute maintain identical 7000-hour lifetime at 105°C and ROHS3 compliance. The UCW1E331MNL1GS is subject to REACH regulations, whereas the main part is REACH Unaffected. Height remains at 0.394" (10.00mm), maintaining original PCB clearance specifications.

Rubycon 10TRV330M8X10.5 (10 V Rating): This substitute offers extended thermal performance with 8000-hour lifetime at 105°C and expanded operating temperature range (-40°C to 105°C). Height increases to 0.413" (10.50mm). REACH status is Unaffected. Ripple current capacity increases to 360 mA at 120 Hz and 600 mA at 100 kHz.

Rubycon 16TRV330M8X10.5 (16 V Rating): This substitute combines higher voltage rating with extended 8000-hour lifetime at 105°C and wider operating temperature range (-40°C to 105°C). Height increases to 0.413" (10.50mm). REACH status is Unaffected. Ripple current specifications match the 10 V variant at 360 mA and 600 mA respectively.

All substitutes maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. Selection should account for PCB height constraints due to 0.019" (0.50mm) increase in seated height for Rubycon variants.

Frequently Asked Questions (FAQ)

Q: Can UCW1E331MNL1GS replace UCB0J331MNL1GS in a 6.3 V circuit?

A: Yes. The UCW1E331MNL1GS maintains identical capacitance (330 µF), tolerance (±20%), and physical footprint. The 25 V rating exceeds the 6.3 V requirement, providing voltage margin. Both parts share identical height (0.394"), land size (8.30mm x 8.30mm), and MSL Level 1 rating. The primary difference is REACH status: UCW1E331MNL1GS is REACH Affected while UCB0J331MNL1GS is REACH Unaffected.

Q: What is the height difference between Nichicon and Rubycon substitutes?

A: Nichicon UCB0J331MNL1GS and UCW1E331MNL1GS are both 0.394" (10.00mm) seated height. Rubycon 10TRV330M8X10.5 and 16TRV330M8X10.5 are 0.413" (10.50mm) seated height, representing a 0.019" (0.50mm) increase. PCB layout must accommodate this height difference to prevent component interference.

Q: Are all substitutes compatible with the same PCB footprint?

A: Surface mount land size is identical across all parts at 0.327" L x 0.327" W (8.30mm x 8.30mm). All parts are surface mount radial can packages with identical diameter (0.315" / 8.00mm). Height variation between Nichicon (10.00mm) and Rubycon (10.50mm) variants must be considered for clearance planning.

Q: Which substitute offers the best thermal performance?

A: Rubycon 10TRV330M8X10.5 and 16TRV330M8X10.5 both provide 8000-hour lifetime at 105°C compared to 7000 hours for the main part and UCW1E331MNL1GS. Both Rubycon variants also support extended operating temperature range of -40°C to 105°C versus -25°C to 105°C for Nichicon parts.

Q: Do all substitutes meet RoHS and MSL requirements?

A: All four parts are ROHS3 Compliant and MSL Level 1 (Unlimited). REACH status differs: UCB0J331MNL1GS, 10TRV330M8X10.5, and 16TRV330M8X10.5 are REACH Unaffected; UCW1E331MNL1GS is REACH Affected. Regulatory requirements for your application region should guide selection.

Q: What voltage rating should I select for my application?

A: Select a substitute with voltage rating equal to or greater than the circuit operating voltage. The main part (6.3 V) is suitable for low-voltage applications. UCW1E331MNL1GS (25 V) provides maximum voltage margin. Rubycon 10TRV330M8X10.5 (10 V) and 16TRV330M8X10.5 (16 V) offer intermediate ratings with extended thermal performance.
