Substitute Part Grouping Explanation

Substitution of the ULD2W8R2MPD is determined by strict equivalence across the following critical parameters:

• Capacitance: 8.2 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can (exact match required)
• Physical Dimensions: 0.394" Dia × 0.866" Height (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lifetime Rating: 20000 Hrs @ 105°C (exact match required)

The substitute part 450LLE8.2MEFC10X20 from Rubycon meets all these criteria, ensuring direct mechanical and electrical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The 450LLE8.2MEFC10X20 from Rubycon is a direct equivalent substitute for the ULD2W8R2MPD. Selection between these parts should be based on the following factors:

• Product Status: The Rubycon part is Active, whereas the Nichicon part is Not For New Designs. For new designs or long-term supply assurance, the Rubycon substitute is the appropriate choice.
• Compliance: Both parts are ROHS3 Compliant and carry the same ECCN and HTSUS classifications, ensuring regulatory equivalence.
• Moisture Sensitivity: The Rubycon part carries MSL 1 (Unlimited), providing superior moisture handling compared to the Nichicon part (Not Applicable).
• Operating Temperature: The Nichicon part supports -40°C minimum operation, while the Rubycon part supports -25°C minimum. Applications requiring operation below -25°C must retain the Nichicon part or identify alternative solutions.
• High-Frequency Ripple Current: The Rubycon part delivers 280 mA @ 100 kHz compared to 167.2 mA for the Nichicon part, providing enhanced performance margin in high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the 450LLE8.2MEFC10X20 be used as a direct replacement for the ULD2W8R2MPD in existing designs?

A: Yes. Both parts share identical capacitance (8.2 µF), voltage rating (450 V), tolerance (±20%), physical dimensions, lead spacing, and lifetime rating (20000 Hrs @ 105°C). Direct substitution is mechanically and electrically compatible.

Q: What is the difference in operating temperature range between these parts?

A: The ULD2W8R2MPD operates from -40°C to 105°C, while the 450LLE8.8MEFC10X20 operates from -25°C to 105°C. Applications requiring operation below -25°C must use the Nichicon part.

Q: Why is the Nichicon part marked "Not For New Designs"?

A: This designation indicates the part has been superseded in Nichicon's active product portfolio. For new designs, the Rubycon equivalent is recommended to ensure long-term availability and manufacturer support.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 Compliant with identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. The Rubycon part carries MSL 1 (Unlimited) versus Not Applicable for the Nichicon part, indicating superior moisture handling.

Q: How do the ripple current ratings compare?

A: At 120 Hz, the Rubycon part delivers 84 mA versus 88 mA for the Nichicon part. At 100 kHz, the Rubycon part delivers 280 mA versus 167.2 mA for the Nichicon part, providing higher ripple current capacity in high-frequency applications.

Q: Are both parts available in the same package configuration?

A: Yes. Both parts are supplied in Radial, Can package with identical lead spacing (0.197" / 5.00mm), diameter (0.394" / 10.00mm), and height (0.866" / 22.00mm), ensuring PCB footprint compatibility.
