Key Parameters

Substitute Part Grouping Explanation

Substitution of the UVR2D331MRD6 is determined by the following critical electrical and mechanical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Rating: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)

The LDM2D331MERYGA meets all critical electrical specifications and maintains identical package classification. Physical dimensions vary within the radial can package category, and ripple current ratings differ due to series design variations. Both components are ROHS3 compliant and suitable for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The LDM2D331MERYGA is a direct electrical equivalent to the UVR2D331MRD6, matching all critical capacitance, voltage, tolerance, and thermal specifications. The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete UVR2D331MRD6.

Both components maintain ROHS3 compliance and identical operating temperature ranges. Physical dimensions differ: the LDM2D331MERYGA features a smaller diameter (20.00mm vs 25.00mm) and reduced lead spacing (7.50mm vs 12.50mm), while maintaining the same seated height. These dimensional differences require PCB layout verification to confirm mechanical compatibility with existing through-hole footprints.

The LDM2D331MERYGA demonstrates higher ripple current capability at high frequencies, providing enhanced performance margin in applications with significant AC ripple content.

Frequently Asked Questions (FAQ)

Q: Can the LDM2D331MERYGA replace the UVR2D331MRD6 in existing designs?

A: Electrical substitution is valid based on matching capacitance (330 µF), voltage rating (200 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), and operating temperature range (-40°C ~ 85°C). Physical dimensions differ; PCB layout compatibility must be confirmed before implementation.

Q: What are the key differences between these two parts?

A: Both parts are Nichicon aluminum electrolytic capacitors with identical electrical specifications. The LDM2D331MERYGA has a smaller physical footprint (20.00mm diameter vs 25.00mm) and tighter lead spacing (7.50mm vs 12.50mm). The LDM series provides higher ripple current ratings. The UVR2D331MRD6 is obsolete; the LDM2D331MERYGA is active production.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance differences exist between the two components.

Q: What should I consider when switching from UVR2D331MRD6 to LDM2D331MERYGA?

A: Verify PCB through-hole pad spacing and diameter compatibility with the reduced lead spacing (7.50mm) and smaller can diameter (20.00mm) of the LDM2D331MERYGA. Confirm that the component fits within available board space and that no mechanical interference occurs with adjacent components.
