UVR2E2R2MED Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2E2R2MED is a 2.2 µF, 250 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This part is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support, production continuity, and component sourcing.

Substitute Part Grouping Explanation

Substitution for the UVR2E2R2MED is determined by the following critical parameters: capacitance value (2.2 µF), voltage rating (250 V or higher), tolerance (±20%), package type (radial can), lead spacing (0.098" / 2.50 mm), and mounting type (through hole). Parts are grouped into three categories based on their relationship to the original specification:

Direct Substitutes maintain identical electrical ratings (2.2 µF, 250 V) and mechanical dimensions, differing only in manufacturer and series designation. These parts are pin-compatible and functionally equivalent for the same application requirements.

Upgrade Substitutes exceed the original specifications in lifetime rating or operating temperature range while maintaining the same capacitance, voltage, and package dimensions. These parts provide enhanced reliability for the same physical footprint.

Parametric Equivalents match the core electrical specifications but may have minor variations in ripple current handling or height dimensions within acceptable tolerances for through-hole radial can packages.

Engineering Selection Recommendations

Direct Substitutes for Pin-Compatible Replacement:

250PK2.2MEFC6.3X11 and 250PK2R2MEFC6.3X11 (Rubycon) are direct functional equivalents with identical electrical specifications and active product status. Both are ROHS3 compliant and suitable for direct board-level replacement where the 0.512" maximum height is acceptable.

ESMG251ELL2R2MF11D (Chemi-Con) matches the original height dimension (0.492") and electrical ratings, providing a compact alternative with active status and ROHS3 compliance.

ECA-2EM2R2 (Panasonic Electronic Components) is functionally equivalent with active status and ROHS3 compliance. The reduced operating temperature minimum (-25°C versus -40°C) should be evaluated against application requirements.

Upgrade Substitutes for Enhanced Reliability:

250LEX2.2MEFC6.3X11 and 250LEX2R2MEFC6.3X11 (Rubycon) provide doubled lifetime rating (4000 hours at 125°C) and extended operating temperature range (-40°C to 125°C) while maintaining identical capacitance and voltage ratings. These are suitable for applications requiring improved thermal performance.

250LLE2.2MEFC6.3X11 (Rubycon) offers the highest lifetime rating (12000 hours at 105°C) with extended operating temperature range (-40°C to 105°C), providing maximum reliability for long-life applications.

Higher Voltage Alternatives:

350PK2.2MEFC6.3X11 (Rubycon) and ESMQ351ELL2R2MF11D (Chemi-Con) provide 350 V rating, suitable for applications requiring voltage margin above the 250 V specification. Both maintain identical capacitance and are ROHS3 compliant with active status.

All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 350 V rated capacitor in place of the 250 V UVR2E2R2MED?

A: Yes. A higher voltage rating is a valid substitution for the same capacitance value. The 350PK2.2MEFC6.3X11 and ESMQ351ELL2R2MF11D both provide 2.2 µF at 350 V, maintaining electrical compatibility while providing additional voltage margin.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (250PK2.2MEFC6.3X11, ESMG251ELL2R2MF11D, ECA-2EM2R2) maintain identical lifetime and temperature specifications as the original part. Upgrade substitutes (250LEX2.2MEFC6.3X11, 250LLE2.2MEFC6.3X11) provide extended lifetime ratings and higher operating temperature ranges for improved reliability in demanding applications.

Q: Are there height restrictions I should consider?

A: The original UVR2E2R2MED has a maximum seated height of 0.492" (12.50 mm). Most substitute parts measure 0.512" (13.00 mm), a 0.020" increase. ESMQ351ELL2R2MF11D and ESMG251ELL2R2MF11D match the original height. Verify clearance in your PCB layout before selection.

Q: Which substitute offers the best long-term reliability?

A: The 250LLE2.2MEFC6.3X11 (Rubycon) provides the highest lifetime rating at 12000 hours at 105°C, making it the optimal choice for applications requiring extended service life and thermal stability.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can I substitute based on ripple current specifications?

A: Ripple current values vary among substitutes (30–50 mA at 120 Hz). Select a part with ripple current equal to or greater than your application requirement. The ECA-2EM2R2 offers the highest ripple current at 50 mA at 120 Hz.
