ULD2D2R2MED Equivalent & Substitute Parts

Part Overview

The Nichicon ULD2D2R2MED is a 2.2 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 procurement. The part delivers 12000 hours of operational life at 105°C and operates across the temperature range of -40°C to 105°C, serving general-purpose applications in through-hole mounted designs.

Substitute Part Grouping Explanation

Substitution for the ULD2D2R2MED is determined by strict equivalence across the following critical parameters: capacitance value (2.2 µF), tolerance (±20%), rated voltage (200 V or higher), lifetime rating (12000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), polarization (polar), lead spacing (0.098" / 2.50mm), case diameter (0.248" / 6.30mm), and through-hole mounting configuration.

The substitute parts are organized into two categories:

Direct Equivalent: Parts matching all electrical and mechanical parameters of the original component, differing only in manufacturer or minor dimensional tolerances within acceptable limits.

Upgrade Equivalent: Parts that exceed the original voltage rating while maintaining all other critical parameters, providing enhanced voltage margin for the same physical footprint and electrical characteristics.

Engineering Selection Recommendations

200LLE2R2MEFC6.3X11 (Rubycon): This direct equivalent provides identical electrical specifications and mechanical dimensions to the ULD2D2R2MED. The part is active in production status and ROHS3 compliant. Height difference of 0.020" (0.50mm) is within acceptable PCB layout tolerances for through-hole applications. This part is suitable for direct replacement in existing designs.

200LLE2.2MEFC6.3X11 (Rubycon): This parametric equivalent matches all critical electrical and mechanical parameters, including the original seated height of 0.492" (12.50mm). The part is active in production and ROHS3 compliant. This option provides exact dimensional compatibility with the original component.

250LLE2.2MEFC6.3X11 (Rubycon): This upgrade equivalent maintains all electrical characteristics while providing a 250 V rated voltage, exceeding the original 200 V specification. The part is active in production and ROHS3 compliant. This option is suitable for applications requiring enhanced voltage margin or where higher voltage rating provides design flexibility. Height is 0.512" (13.00mm), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can I use the 250LLE2.2MEFC6.3X11 in place of the ULD2D2R2MED?

A: Yes. The 250LLE2.2MEFC6.3X11 is an upgrade equivalent with identical capacitance, tolerance, and temperature characteristics. The higher voltage rating (250 V vs. 200 V) is compatible with 200 V circuit requirements. Verify PCB layout accommodates the 0.512" (13.00mm) height.

Q: What is the difference between the two 200 V Rubycon options?

A: Both 200LLE2R2MEFC6.3X11 and 200LLE2.2MEFC6.3X11 are direct equivalents with identical electrical specifications. The primary difference is seated height: 0.512" (13.00mm) versus 0.492" (12.50mm). Select based on PCB layout constraints.

Q: Are all substitute parts through-hole mounted?

A: Yes. All substitute parts are through-hole mounted with 0.098" (2.50mm) lead spacing, matching the original ULD2D2R2MED configuration.

Q: Do the substitute parts meet RoHS compliance?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the original component.

Q: What is the ripple current rating for these capacitors?

A: The Rubycon LLE series parts specify 36 mA @ 120 Hz ripple current at low frequency. The original ULD2D2R2MED does not provide this specification in available documentation.
