UPB2C330MPD Equivalent & Substitute Parts

Part Overview

The UPB2C330MPD is a 33 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The UPB series has been superseded by more advanced Nichicon series and compatible alternatives from other manufacturers that offer improved performance characteristics such as extended lifetime ratings and broader operating temperature ranges while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the UPB2C330MPD is determined by strict equivalence in the following parameters:

Capacitance: 33 µF (exact match required)
Voltage Rating: 160 V minimum (higher voltage ratings are acceptable upgrades)
Tolerance: ±20% (exact match)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Polarization: Polar (exact match required)

Substitute parts are grouped into three categories:

Direct Equivalents maintain all electrical and mechanical parameters at 160 V rating with improved lifetime or performance characteristics.

Voltage Upgrades maintain all mechanical and electrical parameters but increase the voltage rating to 200 V or 250 V, providing enhanced voltage margin in the same physical package.

Packaging Variants offer the same electrical specifications in alternative packaging formats (Cut Tape vs. Bulk).

Engineering Selection Recommendations

For Direct Replacement (160 V, Same Height)

UCS2C330MPD is the primary active-status equivalent. It maintains the original 160 V rating and 0.846" height while offering extended 8000-hour lifetime at 105°C and expanded operating temperature range (-40°C to 105°C). RoHS3 compliance is confirmed.

For Voltage-Upgraded Applications (200 V)

UCS2D330MPD and UCY2D330MPD both provide 200 V rating in the same 0.846" height. UCS2D330MPD offers 8000-hour lifetime with active product status. UCY2D330MPD extends lifetime to 12000 hours with active status and RoHS3 compliance.

For Extended Lifetime Requirements (12000 Hours)

UCY2C330MPD and UCY2D330MPD both deliver 12000-hour lifetime at 105°C with active product status and RoHS3 compliance. UCY2C330MPD maintains 160 V rating; UCY2D330MPD provides 200 V upgrade. Note: UCY2C330MPD has reduced height (0.689" vs. 0.846"), requiring PCB layout verification.

For Highest Voltage Margin (250 V)

UCY2E330MPD provides 250 V rating with 12000-hour lifetime, active status, and RoHS3 compliance in the standard 0.846" height.

For Non-Nichicon Alternatives

160BXC33MEFC10X20 (Rubycon) maintains 160 V rating with 10000-hour lifetime and active status. EKXG161ELL330MJ20S (Chemi-Con) offers 160 V with 8000-hour lifetime and active status. Both are RoHS3 compliant. Height variations require PCB verification.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct replacement?

A: Yes. A 200 V or 250 V rated capacitor is electrically compatible in a 160 V circuit. The higher voltage rating provides additional safety margin. All mechanical parameters (lead spacing, case diameter, mounting type) must remain identical.

Q: What is the impact of different lifetime ratings?

A: Lifetime rating indicates hours of operation at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. Extended lifetime (8000, 10000, or 12000 hours) provides longer service life in high-temperature applications. Selection depends on application duty cycle and thermal environment.

Q: Are there height restrictions I should consider?

A: Yes. UCY2C330MPD and UCY2C330MPD1TD have reduced height (0.689" vs. 0.846" original). Verify PCB clearance and component placement before substitution. Rubycon BXC series parts have slightly increased height (0.866"), also requiring verification.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging is suitable for manual assembly or tube feeding. Cut Tape (CT) packaging is optimized for automated pick-and-place equipment. Electrical specifications are identical; packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Active-status Nichicon parts (UCS, UCY series) are RoHS3 compliant. Rubycon BXC series and Chemi-Con KXG series are RoHS3 compliant. Obsolete Nichicon parts (UPB, UCA) are not RoHS3 compliant. Verify compliance requirements for your application.

Q: Can I substitute with a different manufacturer?

A: Yes, provided all electrical parameters (capacitance, voltage, tolerance) and mechanical parameters (lead spacing, case diameter, height, mounting type) match. Rubycon 160BXC33MEFC10X20 and Chemi-Con EKXG161ELL330MJ20S are qualified alternatives with identical core specifications.

Q: What operating temperature range should I select?

A: The original UPB2C330MPD operates -25°C to 105°C. Active substitutes offer expanded range (-40°C to 105°C), providing better performance in cold environments. Select based on your application's minimum operating temperature requirement.
