Substitute Part Grouping Explanation

Substitution eligibility for the UFW1J331MPD is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 2000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Ripple current ratings: 650 mA @ 120 Hz and 975 mA @ 10 kHz (exact match required)
• Physical dimensions: 0.394" diameter, 0.787" height, 0.197" lead spacing (exact match required)
• Package configuration: Radial, Can, Through Hole (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The UKW1J331MPD meets all specified parameters and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the UFW1J331MPD and UKW1J331MPD are classified as Not For New Designs by Nichicon. Both components maintain ROHS3 compliance and REACH Unaffected status. The UKW1J331MPD represents a direct parametric equivalent with identical electrical performance, thermal ratings, and physical form factor. Selection between these parts should be based on inventory availability and procurement lead times, as both meet equivalent compliance and performance requirements for legacy system maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the UKW1J331MPD be used as a direct replacement for the UFW1J331MPD?

A: Yes. The UKW1J331MPD is a parametric equivalent with identical capacitance, voltage rating, tolerance, lifetime specification, operating temperature range, ripple current ratings, physical dimensions, and package configuration. Both are Nichicon products with ROHS3 compliance.

Q: Are there any physical differences between these parts?

A: No. Both components share identical dimensions: 0.394" diameter, 0.787" seated height, and 0.197" lead spacing. They are both radial, can-type, through-hole mounted capacitors.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that Nichicon has superseded these product lines. For new circuit designs, current-generation alternatives should be evaluated. For legacy system maintenance and repair, these parts remain functionally valid.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the UFW1J331MPD and UKW1J331MPD are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements.

Q: What determines substitution eligibility for this capacitor?

A: Substitution requires exact matching of capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), ripple current specifications (650 mA @ 120 Hz, 975 mA @ 10 kHz), physical dimensions, and package configuration (radial, can, through-hole).
