Substitute Part Grouping Explanation

Substitution for the UKW2A331MHD is determined by strict equivalence across the following critical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Package / Case: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Physical Dimensions: 0.492" Dia (12.50 mm), Height 0.984" (25.00 mm) (exact match required)

All identified substitute parts meet these criteria and are manufactured by Nichicon. The UVR2A331MHD and UFW2A331MHD are direct parametric equivalents with identical electrical and mechanical specifications to the UKW2A331MHD.

Parameter Comparison

Engineering Selection Recommendations

All three parts—UKW2A331MHD, UVR2A331MHD, and UFW2A331MHD—carry identical "Not For New Designs" product status from Nichicon. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The UVR2A331MHD and UFW2A331MHD are direct substitutes for the UKW2A331MHD based on matching electrical and mechanical parameters. Selection between these parts should be based on availability and inventory status. All three parts are suitable for replacement applications in existing systems where the UKW2A331MHD specification is required.

Frequently Asked Questions (FAQ)

Q: Can UVR2A331MHD replace UKW2A331MHD directly?

A: Yes. The UVR2A331MHD meets all critical electrical and mechanical parameters of the UKW2A331MHD, including capacitance (330 µF), voltage rating (100 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (5.00 mm), and physical dimensions (0.492" Dia, 0.984" Height). Direct substitution is supported.

Q: Can UFW2A331MHD replace UKW2A331MHD directly?

A: Yes. The UFW2A331MHD is a parametric equivalent with identical specifications to the UKW2A331MHD across all critical parameters. Direct substitution is supported.

Q: Are there differences in ripple current ratings between these parts?

A: Minor variations exist. The UKW2A331MHD and UFW2A331MHD both specify 750 mA @ 120 Hz and 1.125 A @ 10 kHz. The UVR2A331MHD specifies 760 mA @ 120 Hz and 1.14 A @ 10 kHz. These differences are within normal manufacturing tolerances and do not affect substitution compatibility.

Q: Do all three parts use the same through-hole mounting configuration?

A: Yes. All three parts are through-hole mounted with identical lead spacing (0.197" / 5.00 mm) and package type (Radial, Can). PCB layout compatibility is maintained across all three parts.

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

A: This status indicates that Nichicon has discontinued active development for these series. For new system designs, alternative current-production capacitor series should be evaluated. For existing systems and legacy support, these parts remain available and suitable for replacement.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
