Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECE-V1HS2R2SR must satisfy the following electrical and mechanical criteria:

• Capacitance value of 2.2 µF
• Voltage rating of 50 V or higher
• Tolerance of ±20% or tighter
• Operating temperature range encompassing -40°C to 85°C
• Polar aluminum electrolytic construction
• Surface mount radial can package configuration
• Compatible land pattern dimensions for PCB integration

The UWX1H2R2MCL1GB from Nichicon meets all substitution criteria while offering improved reliability characteristics through extended lifetime rating and enhanced ripple current handling.

Parameter Comparison

Engineering Selection Recommendations

The UWX1H2R2MCL1GB serves as a direct functional substitute for the obsolete ECE-V1HS2R2SR. Both components share identical electrical specifications for capacitance, voltage rating, and tolerance. The Nichicon substitute provides extended operational lifetime (2000 hours versus 1000 hours at 85°C) and improved ripple current capacity, delivering enhanced reliability margins in production applications.

The substitute part carries ROHS3 compliance certification, addressing regulatory requirements for new designs. The physical footprint differs slightly in diameter (4.00mm versus 3.00mm), requiring PCB layout verification to confirm land pattern compatibility. Height remains consistent at 5.40mm maximum, preserving clearance characteristics in existing mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can the UWX1H2R2MCL1GB replace the ECE-V1HS2R2SR in existing designs?

A: Yes, provided PCB land pattern dimensions accommodate the larger 4.00mm diameter. The electrical performance remains equivalent across all specified operating conditions.

Q: What is the significance of the extended lifetime rating in the substitute part?

A: The UWX1H2R2MCL1GB offers 2000 hours at 85°C compared to 1000 hours for the original part. This extended rating indicates improved electrolyte formulation and construction, reducing degradation rates in thermal stress conditions.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: RoHS3 compliance indicates the substitute part meets current environmental and material restriction standards. This is advantageous for new production and regulatory compliance, with no negative impact on electrical or mechanical compatibility.

Q: Are there dimensional constraints when substituting this component?

A: The substitute part has a larger diameter (4.00mm versus 3.00mm) but maintains identical height (5.40mm). PCB layout must accommodate the increased footprint. The land pattern size increases from 3.30mm to 4.30mm square.

Q: What packaging format is available for the substitute part?

A: The UWX1H2R2MCL1GB is supplied in Tape & Reel (TR) format, standard for surface mount production environments.
