Key Parameters

Substitute Part Grouping Explanation

Substitution for the UMA1V2R2MCD2 is determined by the following critical parameters:

• Capacitance Value: Must be 2.2 µF (±20% tolerance acceptable)
• Voltage Rating: Substitute must meet or exceed 35 V rated voltage
• Polarization: Must remain polar (aluminum electrolytic)
• Mounting Type: Must be through-hole compatible
• Package Style: Radial, can configuration
• Thermal Performance: Lifetime rating of 2000 Hrs @ 85°C or greater
• Compliance: ROHS3 compliant status required

The UVR1H2R2MDD qualifies as a direct substitute based on these parameters. It maintains identical capacitance and tolerance, exceeds the voltage requirement (50 V vs. 35 V), and matches all mechanical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

The UVR1H2R2MDD is the qualified substitute for UMA1V2R2MCD2 based on the following engineering criteria:

• Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements
• The substitute maintains identical electrical performance at the specified capacitance and tolerance
• The 50 V voltage rating of the substitute exceeds the 35 V requirement, providing additional safety margin in the application circuit
• Both components share identical thermal performance (2000 Hrs @ 85°C) and operating temperature range
• Physical compatibility is maintained through identical radial, can package configuration and through-hole mounting
• Both parts are manufactured by Nichicon, ensuring consistent quality and reliability standards

Selection of the UVR1H2R2MDD does not require circuit redesign or additional qualification when replacing the obsolete UMA1V2R2MCD2.

Frequently Asked Questions (FAQ)

Q: Can the UVR1H2R2MDD be used as a direct replacement for UMA1V2R2MCD2?

A: Yes. Both parts share identical capacitance (2.2 µF), tolerance (±20%), thermal performance (2000 Hrs @ 85°C), and package configuration (radial, can, through-hole). The substitute's higher voltage rating (50 V vs. 35 V) is compatible with circuits designed for 35 V operation.

Q: Are there physical dimension differences between these parts?

A: Yes. The UVR1H2R2MDD has larger physical dimensions (0.197" diameter, 0.492" height) compared to the UMA1V2R2MCD2 (0.118" diameter, 0.236" height). Lead spacing also differs (0.079" vs. 0.039"). PCB layout verification is required before substitution.

Q: Do both parts meet current compliance standards?

A: Yes. Both the UMA1V2R2MCD2 and UVR1H2R2MDD are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

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

A: The UVR1H2R2MDD has higher ripple current ratings (28 mA @ 120 Hz, 56 mA @ 10 kHz) compared to the UMA1V2R2MCD2 (8.4 mA @ 120 Hz, 12.6 mA @ 10 kHz). This difference reflects the larger physical size and does not affect substitution compatibility.

Q: Are both parts still available for procurement?

A: Both parts are listed as obsolete. Current inventory availability should be confirmed with authorized distributors before design implementation.
