Substitute Part Grouping Explanation

Substitution of the ULD2D100MPD is based on strict parametric equivalence across the following critical specifications:

• Capacitance value: 10 µF (exact match required)
• Rated voltage: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lifetime rating: 15000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Physical dimensions: 0.315" Dia (8.00mm), 0.531" (14.60mm) height, 0.138" (4.60mm) lead spacing (exact match required)
• Mounting type: Through Hole, Radial Can package (exact match required)
• RoHS3 compliance (required for regulatory alignment)

The substitute part 200LLE10MEFC8X11.5 from Rubycon meets all these parametric requirements and is classified as an active product, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The 200LLE10MEFC8X11.5 from Rubycon is the direct parametric equivalent for the ULD2D100MPD. Selection of the Rubycon substitute is supported by the following factors:

• The substitute part maintains all critical electrical and mechanical specifications required for direct replacement
• The Rubycon part is classified as active product status, ensuring continued manufacturing and supply availability
• Both parts are ROHS3 compliant, meeting current regulatory requirements
• The substitute part demonstrates higher ripple current capability at 100 kHz (152 mA versus 128 mA), providing additional performance margin in high-frequency applications
• Physical footprint and lead spacing are identical, enabling direct PCB compatibility without layout modifications

Frequently Asked Questions (FAQ)

Q: Can the 200LLE10MEFC8X11.5 be used as a direct replacement for the ULD2D100MPD?

A: Yes. Both parts share identical capacitance (10 µF), voltage rating (200 V), tolerance (±20%), lifetime rating (15000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and physical dimensions. The parts are mechanically and electrically interchangeable.

Q: What is the difference in ripple current between these parts?

A: At 100 kHz, the Rubycon part (200LLE10MEFC8X11.5) provides 152 mA ripple current capacity compared to 128 mA for the Nichicon part (ULD2D100MPD). At 120 Hz, both parts are rated for 80 mA. The higher high-frequency ripple current in the substitute part does not create compatibility issues and may provide additional design margin.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use identical lead spacing (0.138" / 4.60mm), can diameter (0.315" / 8.00mm), and height (0.531" / 14.60mm). No PCB modifications are required for substitution.

Q: Why is the ULD2D100MPD marked as "Not For New Designs"?

A: This designation indicates the part has been superseded in Nichicon's active product portfolio. For new designs and ongoing production, the Rubycon 200LLE10MEFC8X11.5 is the recommended equivalent, offering the same electrical performance with active product status and assured supply continuity.

Q: Are both parts RoHS compliant?

A: Yes. Both the ULD2D100MPD and 200LLE10MEFC8X11.5 are ROHS3 compliant, meeting current environmental and regulatory standards.
