Equivalent & Substitute Parts for UPB2D330MHD1TO

Part Overview

The UPB2D330MHD1TO is a 33 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing applications. The original series offers a 5000-hour lifetime rating at 105°C with general-purpose applications in through-hole mounting configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the UPB2D330MHD1TO is determined by the following critical parameters:

Capacitance Value: 33 µF (exact match required)
Voltage Rating: Minimum 200 V (equal or higher acceptable)
Tolerance: ±20% (matching tolerance)
Polarization: Polar (required)
Package Configuration: Radial, Can with through-hole mounting
Lead Spacing: 0.197" (5.00 mm) (exact match for PCB compatibility)
Case Diameter: 0.492" (12.50 mm) (exact match for mechanical fit)
Operating Temperature Range: -25°C to 105°C (minimum requirement)

Two substitute parts meet these criteria: the Nichicon UCA2D330MHD1TO and the Rubycon 250BXC33MEFC12.5X16. Both maintain identical electrical specifications and mechanical dimensions while offering extended lifetime ratings.

Engineering Selection Recommendations

UCA2D330MHD1TO (Nichicon): This substitute maintains identical electrical and mechanical specifications to the original UPB2D330MHD1TO while providing doubled lifetime (12000 hours versus 5000 hours at 105°C). The part is RoHS3 compliant and REACH unaffected. Product status is "Not For New Designs," indicating it remains available for replacement applications but is not recommended for new development.

250BXC33MEFC12.5X16 (Rubycon): This substitute provides a 250 V voltage rating (50 V higher than the original 200 V specification), extended 12000-hour lifetime, and active product status. The part is RoHS3 compliant and REACH unaffected. The reduced seated height (0.709" versus 0.846") may provide space advantages in constrained layouts. Higher ripple current ratings at both 120 Hz and 100 kHz offer improved performance margin.

For applications requiring continued support and compliance with current standards, the Rubycon 250BXC33MEFC12.5X16 is the preferred selection due to active product status and higher voltage rating margin.

Frequently Asked Questions (FAQ)

Q: Can the UCA2D330MHD1TO directly replace the UPB2D330MHD1TO?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (200 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (12.50 mm), and height (21.50 mm). The UCA2D330MHD1TO provides extended lifetime (12000 hours versus 5000 hours at 105°C) with no electrical or mechanical incompatibility.

Q: Can the Rubycon 250BXC33MEFC12.5X16 replace the UPB2D330MHD1TO?

A: Yes. The Rubycon part maintains identical capacitance, tolerance, lead spacing, and case diameter. The 250 V voltage rating exceeds the original 200 V specification, providing additional voltage margin. The reduced height (0.709" versus 0.846") is compatible with through-hole PCB layouts. Ripple current ratings are equal or superior.

Q: What is the significance of the voltage rating difference between 200 V and 250 V?

A: The 250 V rating on the Rubycon part provides a 25% voltage safety margin above the original 200 V specification. This higher rating does not affect capacitance value or physical dimensions and is suitable for applications designed for 200 V operation.

Q: Are there mechanical compatibility concerns with the reduced height of the Rubycon part?

A: No. The Rubycon 250BXC33MEFC12.5X16 has a seated height of 0.709" (18.00 mm) compared to 0.846" (21.50 mm) for the original. This reduced height is compatible with existing through-hole PCB layouts and may provide space advantages in compact designs.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete parts are no longer manufactured or supported. "Not For New Designs" indicates the part remains available for replacement and maintenance applications but is not recommended for new product development. The Rubycon part carries Active status, indicating full manufacturer support and availability.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the Nichicon UCA2D330MHD1TO and Rubycon 250BXC33MEFC12.5X16 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
