Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UFW1V331MPD is determined by strict alignment of electrical and mechanical parameters. The critical parameters that define substitutability are:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Case diameter: 0.394" (10.00 mm) (exact match required)
• Height: 0.492" (12.50 mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The UFW1V331MPD has one parametric equivalent substitute: UKW1V331MPD. Both parts share identical electrical specifications, physical dimensions, and compliance certifications. The primary distinction is the manufacturer series designation (UFW versus UKW) and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both UFW1V331MPD and UKW1V331MPD are functionally equivalent for applications requiring 330 µF, 35 V aluminum electrolytic capacitors with 2000-hour lifetime ratings at 85°C. Both parts carry identical RoHS3 compliance and REACH unaffected status, making them suitable for regulated applications.

Selection between these two parts should be based on inventory availability and supply chain considerations. The UFW1V331MPD maintains higher stock levels (6356 units) compared to UKW1V331MPD (2929 units). Both parts are designated "Not For New Designs" by Nichicon, indicating they are maintained for legacy system support and repair applications only.

Frequently Asked Questions (FAQ)

Q: Can UKW1V331MPD be used as a direct replacement for UFW1V331MPD?

A: Yes. Both parts are parametric equivalents with identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), physical dimensions, lead spacing, lifetime rating (2000 Hrs @ 85°C), and operating temperature range (-40°C ~ 85°C). They are mechanically and electrically interchangeable.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts share identical case diameter (0.394" / 10.00 mm), height (0.492" / 12.50 mm), and lead spacing (0.197" / 5.00 mm). They are pin-compatible and fit the same PCB footprint.

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

A: This designation indicates that Nichicon has discontinued active development and marketing of these series for new applications. However, both parts remain in production and available for legacy system maintenance, repair, and replacement applications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both UFW1V331MPD and UKW1V331MPD are ROHS3 compliant and REACH unaffected, meeting the same regulatory standards for restricted substances and environmental compliance.

Q: What is the difference between the UFW and UKW series designations?

A: The series designation reflects Nichicon's internal product line classification. Despite different series names, these parts are parametric equivalents with no functional or performance differences for the specified electrical and mechanical parameters.
