Engineering Selection Recommendations

Direct Parametric Equivalent (160 V Rating): ESMG161ELL4R7MF11D from Chemi-Con provides exact electrical and mechanical compatibility with the UVR2C4R7MED. This part matches all primary substitution criteria and maintains identical operating temperature range and lifetime specifications. Active product status ensures ongoing availability and supply chain stability.

Voltage-Upgraded Substitutes (200 V Rating): ESMQ201ELL4R7MF11D (Chemi-Con) and the Rubycon LEX series (200LEX4.7MEFC6.3X11, 200LEX4R7MEFC6.3X11) provide higher voltage ratings while maintaining identical capacitance, tolerance, and mechanical form factor. These parts are suitable for applications where voltage margin improvement is beneficial. The Rubycon LEX series offers extended lifetime (4000 Hrs @ 125°C) and expanded operating temperature range (-40°C to 125°C).

Extended Lifetime Substitutes (200 V Rating): The Rubycon LLE series (200LLE4R7MEFC6.3X11, 200LLE4R7MEFCMZ6.3X11) delivers superior reliability with 12000 hours lifetime at 105°C, suitable for applications requiring extended service life. These parts maintain 200 V rating and identical mechanical dimensions with slight height increase (0.512" vs 0.492").

Voltage-Upgraded Substitutes (250 V Rating): UVK2E4R7MED (Nichicon) and 250PK4.7MEFC6.3X11 (Rubycon) provide 250 V rating with identical mechanical form factor and lifetime specifications. These parts are appropriate for designs requiring maximum voltage margin.

Similar Voltage Rating Substitute: ECA-2CM4R7 from Panasonic Electronic Components matches the 160 V rating and all electrical specifications. This part is active and available. Note: Operating temperature range is -25°C to 85°C (does not extend to -40°C lower limit).

All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated at 200 V or 250 V can replace the 160 V UVR2C4R7MED in applications where the circuit voltage does not exceed 160 V. Higher voltage ratings provide additional safety margin and do not degrade performance in lower-voltage applications.

Q: What is the significance of the height difference between substitute parts? A: The UVR2C4R7MED has a maximum seated height of 0.492" (12.50 mm). Rubycon LEX and LLE series parts measure 0.512" (13.00 mm). This 0.020" (0.50 mm) difference must be evaluated against PCB layout constraints and available vertical clearance. Panasonic ECA-2CM4R7 measures 0.480" (12.20 mm), providing a slightly more compact profile.

Q: Are all substitute parts through-hole radial components? A: Yes. All listed substitute parts maintain through-hole mounting with radial lead configuration and 0.098" (2.50 mm) lead spacing, ensuring direct PCB footprint compatibility with the original UVR2C4R7MED.

Q: What is the difference between Rubycon LEX and LLE series? A: Both series maintain 4.7 µF capacitance and 200 V rating with identical mechanical form factor. The LEX series provides 4000 hours lifetime at 125°C with operating range to 125°C. The LLE series provides extended 12000 hours lifetime at 105°C with operating range to 105°C. Selection depends on application temperature profile and required service life.

Q: Why is the UVR2C4R7MED classified as obsolete? A: Obsolete status indicates the part is no longer manufactured by Nichicon. Active substitute parts from Chemi-Con, Rubycon, and Panasonic provide equivalent or superior performance and ensure long-term design support and production continuity.

Q: Can I substitute ECA-2CM4R7 if my application requires -40°C operation? A: No. The Panasonic ECA-2CM4R7 operates from -25°C to 85°C and does not meet the -40°C lower temperature limit. Use ESMG161ELL4R7MF11D or other substitutes with -40°C minimum operating temperature for applications requiring full temperature range coverage.

Q: What ripple current specifications should I consider? A: Ripple current ratings vary among substitute parts. The original UVR2C4R7MED specifies 50 mA @ 120 Hz and 80 mA @ 10 kHz. Chemi-Con SMQ and SMG series parts provide higher ripple current capacity (125 mA @ 100 kHz), while Rubycon LEX and LLE series provide 98 mA @ 100 kHz. Select a substitute with ripple current rating equal to or exceeding your application requirement.
