UVZ2C2R2MED Equivalent & Substitute Parts

Part Overview

The UVZ2C2R2MED is a 2.2 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The UVZ series offers a 1000-hour lifetime rating at 105°C with general-purpose applications in through-hole configurations.

Substitute Part Grouping Explanation

Substitution for the UVZ2C2R2MED is determined by the following critical parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: Minimum 160 V (equal or higher voltage ratings are acceptable)
Tolerance: ±20% (standard tolerance for this category)
Package: Radial, can configuration with 0.098" (2.50 mm) lead spacing
Mounting: Through-hole only
Polarization: Polar (aluminum electrolytic)
Operating Temperature: -40°C ~ 105°C minimum range
RoHS Compliance: ROHS3 Compliant

Substitute parts are grouped into two categories: direct equivalents (matching 160 V rating) and upgraded alternatives (higher voltage ratings of 200 V or 250 V). Direct equivalents maintain identical electrical performance. Upgraded alternatives provide higher voltage headroom and extended lifetime ratings, suitable for applications requiring enhanced reliability.

Engineering Selection Recommendations

Direct Equivalent (160 V Rating): SEK2R2M160ST from Cornell Dubilier Electronics is the primary direct equivalent. This part maintains the 160 V voltage rating and 2.2 µF capacitance while offering double the lifetime (2000 Hrs @ 105°C versus 1000 Hrs). The SEK2R2M160ST carries active product status and ROHS3 compliance, making it suitable for new designs and production continuity.

Nichicon Alternatives (160 V Rating): UPW2C2R2MED provides a Nichicon-sourced alternative with improved lifetime (2000 Hrs @ 105°C) and reduced height (0.433" versus 0.492"), though it is classified as obsolete. This option is suitable only if existing inventory or design constraints require Nichicon sourcing.

Upgraded Alternatives (200 V and 250 V Ratings): For applications permitting higher voltage ratings, Rubycon LLE series parts (200LLE2.2MEFC6.3X11, 250LLE2.2MEFC6.3X11) offer extended lifetime ratings (12000 Hrs @ 105°C) with active product status. Rubycon LEX series parts (200LEX2.2MEFC6.3X11, 250LEX2.2MEFC6.3X11) provide 4000-hour lifetimes at elevated temperature (125°C). These upgrades are electrically compatible and provide enhanced reliability margins through higher voltage ratings and extended operational lifetimes.

All substitute parts maintain ROHS3 compliance and through-hole radial can packaging with 0.098" (2.50 mm) lead spacing, ensuring mechanical and environmental compatibility with the original UVZ2C2R2MED design.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V or 250 V rated capacitor in place of the 160 V UVZ2C2R2MED? A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. A 200 V or 250 V capacitor will function correctly in a 160 V application. The higher voltage rating provides additional safety margin and does not affect circuit performance.

Q: What is the difference between direct equivalents and upgraded alternatives? A: Direct equivalents (SEK2R2M160ST, UPW2C2R2MED) maintain the 160 V rating. Upgraded alternatives use 200 V or 250 V ratings with extended lifetime specifications. Both categories are functionally compatible; the choice depends on application requirements and design margins.

Q: Does the height difference between parts affect PCB layout? A: Yes. The UVZ2C2R2MED has a maximum height of 0.492" (12.50 mm). Some substitutes are shorter (0.433" for UPW2C2R2MED) or taller (0.512" for Rubycon LEX and LLE series). Verify PCB clearance and component spacing before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance, matching the environmental certification of the original UVZ2C2R2MED.

Q: Which substitute offers the longest operational lifetime? A: Rubycon LLE series parts (200LLE2.2MEFC6.3X11, 200LLE2R2MEFC6.3X11, 250LLE2.2MEFC6.3X11) provide 12000-hour lifetimes at 105°C, compared to 1000 hours for the original UVZ2C2R2MED.

Q: Can I mix different substitute parts in the same design? A: Yes, provided all parts meet the circuit's voltage and capacitance requirements. However, using a single part number across production is recommended for consistency and supply chain management.

Q: What is the lead spacing for all substitute parts? A: All substitute parts maintain 0.098" (2.50 mm) lead spacing, ensuring compatibility with existing PCB footprints designed for the UVZ2C2R2MED.
