UPB2D330MHD Equivalent & Substitute Parts

Part Overview

The Nichicon UPB2D330MHD is a 33 µF, 200 V aluminum electrolytic capacitor in radial, can package configuration. 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 The UPB series has been superseded by more advanced Nichicon lines offering extended operational lifetime and improved performance characteristics while maintaining identical mechanical and electrical core specifications.

Upgrade substitutes may offer extended lifetime (10000-12000 Hrs @ 105°C)
Operating temperature range may be extended in upgrade parts (-40°C to 105°C vs. -25°C to 105°C)

Ripple Current:

Direct substitutes maintain minimum 300 mA @ 120 Hz and 600 mA @ 100 kHz
Upgrade substitutes may offer equal or higher ripple current ratings

Engineering Selection Recommendations

Direct Substitutes (Same Voltage Class - 200 V):

UCA2D330MHD and 336TXK200M are direct electrical substitutes for UPB2D330MHD. Both maintain 200 V voltage rating and identical capacitance, tolerance, and package specifications. UCA2D330MHD offers extended lifetime (12000 Hrs vs. 5000 Hrs) while remaining within the Nichicon product family. The 336TXK200M from Cornell Dubilier / Illinois Capacitor provides an alternative manufacturer source with active product status and ROHS3 compliance. Height variation of 0.020" (0.50 mm) on the 336TXK200M is within typical PCB layout tolerances for through-hole radial capacitors.

Upgrade Substitutes (Higher Voltage Rating - 250 V and 350 V):

UCS2E330MHD, UCY2E330MHD3, and UCY2V330MHD from Nichicon, along with 250BXC33MEFC12.5X20, 250CFX33M12.5X20, and 250CFX33MEFC12.5X20 from Rubycon, and EEU-EE2E330 from Panasonic are upgrade substitutes with voltage ratings of 250 V or higher. These parts are electrically compatible in applications rated for 200 V operation. All upgrade substitutes carry active product status and ROHS3 compliance. Extended operating temperature range (-40°C vs. -25°C minimum) is available in Nichicon UCY and UCS series. Lifetime ratings range from 5000 to 12000 Hrs @ 105°C.

Height Considerations:

250BXC33MEFC12.5X16 has a reduced height of 0.709" (18.00 mm) compared to the original 0.846" (21.50 mm). This part is suitable only for applications where reduced height is required and PCB layout permits. All other substitutes maintain height compatibility within 0.020" (0.50 mm) of the original specification.

Compliance and Availability:

All active substitute parts listed carry ROHS3 compliance. Nichicon UCA2D330MHD, though obsolete, offers extended lifetime. For new designs and production continuity, active-status parts (UCS2E330MHD, UCY2E330MHD3, UCY2V330MHD, Rubycon BXC and CFX series, Panasonic EEU-EE2E330) are recommended.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of a 200 V rated capacitor?

A: Yes. A higher voltage-rated capacitor is electrically compatible in applications designed for lower voltage operation. The 250 V and 350 V rated substitutes listed are suitable for any application originally specified for 200 V operation.

Q: What is the significance of the height difference in 250BXC33MEFC12.5X16?

A: This part has a maximum seated height of 0.709" (18.00 mm) versus the original 0.846" (21.50 mm). Use this part only if your PCB layout specifically requires reduced height. Standard height substitutes maintain the original 0.846" (21.50 mm) specification.

Q: Are all substitute parts ROHS3 compliant?

A: All active-status substitute parts listed carry ROHS3 compliance. The original UPB2D330MHD and obsolete UCA2D330MHD do not list RoHS status. For applications requiring ROHS3 compliance, select from the active-status parts.

Q: What is the difference between direct and upgrade substitutes?

A: Direct substitutes maintain the same 200 V voltage rating as the original part. Upgrade substitutes have 250 V or 350 V ratings, offering higher voltage margin and typically extended operational lifetime. Both categories maintain identical capacitance, tolerance, package, and lead spacing.

Q: Can I interchange parts from different manufacturers?

A: Yes, provided all electrical and mechanical parameters match exactly. Nichicon, Rubycon, Cornell Dubilier / Illinois Capacitor, and Panasonic parts listed all meet the core compatibility requirements of 33 µF, ±20%, 200 V or higher, radial can package, 5.00 mm lead spacing, and through-hole mounting.

Q: Which substitute offers the longest operational lifetime?

A: UCY2E330MHD3 and UCY2V330MHD from Nichicon, along with 250BXC33MEFC12.5X20 from Rubycon, all offer 12000 Hrs @ 105°C operational lifetime, compared to the original 5000 Hrs @ 105°C.

Q: Is the ripple current rating important for substitution?

A: Ripple current capacity must meet or exceed the original specification. The original UPB2D330MHD specifies 300 mA @ 120 Hz and 600 mA @ 100 kHz. All listed substitutes meet or exceed these ratings.
