UCS2D330MPD Equivalent & Substitute Parts

Part Overview

The UCS2D330MPD is a 33 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for general purpose applications with an operational lifetime of 8000 hours at 105°C and operates across a temperature range of -40°C to 105°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCS2D330MPD is permissible when the following electrical and mechanical parameters are maintained or exceeded:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: minimum 200 V (equal or higher acceptable)
• Tolerance: ±20% (matching tolerance required)
• Lead spacing: 0.197" (5.00mm) (exact match required for PCB compatibility)
• Physical dimensions: 0.394" Dia (10.00mm) and 0.846" (21.50mm) height (exact match required for mechanical fit)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Polarization: Polar (exact match required)
• Operating temperature range: -40°C ~ 105°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The EKXJ251ELL330MJ20S meets all substitution criteria with identical electrical and mechanical specifications, with the exception of an elevated voltage rating (250 V vs. 200 V) and extended lifetime rating (10000 Hrs @ 105°C vs. 8000 Hrs @ 105°C), both of which represent performance improvements.

Parameter Comparison

Engineering Selection Recommendations

The EKXJ251ELL330MJ20S is a direct mechanical and electrical substitute for the UCS2D330MPD. Both components are active products with ROHS3 compliance. The substitute part provides a higher voltage rating (250 V) and extended operational lifetime (10000 Hrs @ 105°C), making it suitable for applications requiring enhanced reliability margins. Selection between the two components should be based on application voltage requirements, supply availability, and cost considerations. The identical physical footprint and lead spacing ensure PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the EKXJ251ELL330MJ20S replace the UCS2D330MPD in all applications?
