UVK2G3R3MPD1TD Equivalent & Substitute Parts

Part Overview

The UVK2G3R3MPD1TD is a 3.3 µF, 400 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is designated as Not For New Designs. Due to its obsolescence status and limited thermal performance specification, identifying equivalent substitute parts with extended operational life and improved temperature ratings is necessary for design continuity and long-term reliability in applications requiring higher thermal endurance.

Substitute Part Grouping Explanation

Substitution of the UVK2G3R3MPD1TD is determined by strict equivalence in the following electrical and mechanical parameters:

• Capacitance value: 3.3 µF (exact match required)
• Voltage rating: 400 V (minimum requirement)
• Tolerance: ±20% (acceptable range)
• Polarization: Polar (radial aluminum electrolytic)
• Package configuration: Radial, Can through-hole mounting
• Lead spacing: 0.138" (4.60mm)
• Physical diameter: 0.315" (8.00mm)

The ULD2G3R3MPD1TD qualifies as a direct substitute based on matching all critical electrical specifications and mechanical form factors. The substitute part provides enhanced operational characteristics including extended lifetime rating (15000 Hrs @ 105°C versus 2000 Hrs @ 85°C) and expanded operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

The ULD2G3R3MPD1TD is a qualified substitute for the UVK2G3R3MPD1TD based on electrical and mechanical parameter equivalence. Both components are ROHS3 compliant and manufactured by Nichicon. The substitute part offers extended lifetime rating and higher maximum operating temperature, providing improved reliability margins in thermal environments. The height difference of 0.019" (0.50mm) between the two parts is within typical PCB layout tolerances for through-hole radial capacitors. Both parts maintain identical lead spacing and footprint compatibility for direct board-level replacement.
