UVR2G101MRD Equivalent & Substitute Parts

Part Overview

The UVR2G101MRD is a 100 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Obsolete, indicating it is no longer in active production. Finding equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UVR2G101MRD is determined by the following critical parameters:

• Electrical Equivalence: Capacitance (100 µF), rated voltage (400 V), and tolerance (±20%) must match exactly
• Thermal Performance: Lifetime rating of 2000 Hrs @ 85°C and operating temperature range of -40°C ~ 85°C must be maintained
• Mechanical Compatibility: Through-hole mounting, radial can package, and lead spacing of 0.394" (10.00 mm) are required for direct PCB substitution
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved

The UVK2G101MHD manufactured by Nichicon meets all electrical and thermal specifications. However, it exhibits reduced physical dimensions (0.709" Dia, 1.476" Height, 0.295" Lead Spacing) and lower ripple current ratings, requiring mechanical and thermal validation before substitution.

Parameter Comparison

Engineering Selection Recommendations

The UVK2G101MHD is electrically and thermally equivalent to the UVR2G101MRD. Both components maintain identical capacitance, voltage rating, tolerance, and thermal lifetime specifications. Both are ROHS3 compliant and REACH unaffected.

The UVK2G101MHD is classified as "Not For New Designs," indicating limited future availability. For legacy system support or repair applications where the original UVR2G101MRD is unavailable, the UVK2G101MHD provides electrical continuity. However, the reduced physical dimensions and lower ripple current ratings require PCB layout validation to confirm mechanical fit and thermal performance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the UVK2G101MHD be used as a direct replacement for the UVR2G101MRD?

A: Electrical and thermal specifications are identical. However, the UVK2G101MHD has smaller physical dimensions (0.709" Dia vs. 0.787" Dia, 1.476" Height vs. 1.654" Height) and different lead spacing (0.295" vs. 0.394"). PCB layout compatibility must be confirmed before substitution.

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

A: The primary differences are physical dimensions, lead spacing, and ripple current ratings. The UVK2G101MHD delivers 440 mA @ 120 Hz and 704 mA @ 10 kHz compared to 550 mA @ 120 Hz and 880 mA @ 10 kHz for the UVR2G101MRD. Electrical performance (capacitance, voltage, tolerance, lifetime) is identical.

Q: Are both parts RoHS compliant?

A: Yes, both the UVR2G101MRD and UVK2G101MHD are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the product status classifications?

A: The UVR2G101MRD is classified as Obsolete, meaning it is no longer manufactured. The UVK2G101MHD is classified as Not For New Designs, indicating it remains available but is not recommended for new product development. Both statuses indicate limited long-term supply availability.
