Substitute Part Grouping Explanation

Substitution of the UKW1J331MPD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting configuration: Through-hole radial, can package
• Physical dimensions: 10.00 mm diameter, 20.00 mm height, 5.00 mm lead spacing
• Thermal performance: 2000 Hrs @ 85°C minimum
• Operating temperature range: -40°C ~ 85°C
• Ripple current specifications: 650 mA @ 120 Hz, 975 mA @ 10 kHz
• Compliance: ROHS3 compliant

The UFW1J331MPD from Nichicon meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the UKW1J331MPD and UFW1J331MPD are manufactured by Nichicon and carry identical electrical and mechanical specifications. The UFW series represents a direct parametric equivalent suitable for applications currently using the UKW series.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer electronics applications. The identical thermal rating of 2000 hours at 85°C ensures equivalent reliability performance in audio and general-purpose filtering applications.

Selection between these parts should be based on availability and supply chain considerations, as both deliver equivalent functional performance within the specified operating parameters.
