UVZ2C2R2MEH Equivalent & Substitute Parts

Part Overview

The Nichicon UVZ2C2R2MEH is a 2.2 µF, 160 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 1000 hours at 105°C. This part is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent and substitute parts with improved specifications are available from multiple manufacturers. Substitutes maintain the core electrical parameters (2.2 µF capacitance, ±20% tolerance, radial through-hole mounting) while offering enhanced reliability, extended lifetime ratings, higher voltage ratings, or improved compliance certifications.

Voltage Rating: Minimum 160 V; higher ratings (200 V, 250 V) are acceptable as they provide backward compatibility
Mounting Type: Must be through-hole radial, can package
Lead Spacing: Must be 0.098" (2.50 mm)
Size / Dimension: Diameter 0.248" (6.30 mm); height variations within package constraints are acceptable
Polarization: Must remain polar
Operating Temperature Range: Must support -40°C ~ 105°C minimum; extended ranges are acceptable

Engineering Selection Recommendations

For Direct Replacement (160 V Rating):

SEK2R2M160ST (Cornell Dubilier Electronics) is the preferred direct equivalent. It is active in production, ROHS3 compliant, and offers doubled lifetime (2000 hours at 105°C) compared to the obsolete UVZ2C2R2MEH. Physical dimensions are compatible with standard PCB layouts. This part is suitable for applications where the 160 V rating is specified and compliance with RoHS3 is required.

UPW2C2R2MED (Nichicon UPW series) is an alternative direct equivalent, also obsolete but available in inventory. It provides 2000 hours lifetime at 105°C and ROHS3 compliance. Height is slightly reduced (0.433" vs. 0.492"), which may require PCB layout verification.

For Upgraded Performance (200 V or 250 V Rating):

200LLE2.2MEFC6.3X11 (Rubycon LLE series, 200 V) offers the highest lifetime rating at 12000 hours at 105°C with active production status and ROHS3 compliance. Height matches the original part (0.492"). This upgrade is suitable for applications where extended reliability is prioritized and the circuit can tolerate 200 V rating.

250LLE2.2MEFC6.3X11 (Rubycon LLE series, 250 V) provides the same 12000-hour lifetime with higher voltage margin. This is the optimal choice for new designs or applications requiring maximum reliability and compliance.

250LEX2.2MEFC6.3X11 and 250LEX2R2MEFC6.3X11 (Rubycon LEX series, 250 V) offer 4000 hours at 125°C with extended operating temperature range. These are suitable for applications with elevated ambient temperatures.

250PX2.2MEFC6.3X11 and 250PX2R2MEFC6.3X11 (Rubycon PX series, 250 V) match the original 1000-hour lifetime specification at 105°C while providing higher voltage rating and ROHS3 compliance. These are cost-effective upgrades for direct replacement scenarios.

All recommended substitutes maintain the 2.2 µF capacitance, ±20% tolerance, radial through-hole mounting, 0.098" lead spacing, and 0.248" diameter. Physical height variations (0.433" to 0.512") must be verified against PCB clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of a 160 V rated capacitor?

A: Yes. Higher voltage ratings provide backward compatibility. A 250 V capacitor can be used in a 160 V application without electrical degradation. The circuit will operate within safe margins. Physical dimensions must be verified for PCB fit.

Q: What is the difference between the Rubycon LLE and LEX series?

A: Both are 2.2 µF aluminum electrolytic capacitors in radial, can package with identical lead spacing and diameter. The LLE series offers 12000 hours lifetime at 105°C across 200 V and 250 V ratings. The LEX series offers 4000 hours lifetime at 125°C. Select LLE for maximum lifetime at standard operating temperatures; select LEX for applications with elevated ambient temperatures.

Q: Does the height difference between substitutes affect PCB compatibility?

A: Height variations range from 0.433" (11.00 mm) to 0.512" (13.00 mm). The original UVZ2C2R2MEH is 0.492" (12.50 mm). Verify clearance above the capacitor on your PCB. Shorter substitutes (UPW2C2R2MED, SEK2R2M160ST at 0.433") provide additional clearance. Taller substitutes (Rubycon series at 0.512") require 0.020" additional clearance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitutes are ROHS3 compliant. The original UVZ2C2R2MEH is RoHS non-compliant. Compliance is required for most modern applications and regulatory environments.

Q: What is the difference between UPW2C2R2MED and SEK2R2M160ST?

A: Both are 160 V, 2.2 µF direct equivalents with 2000 hours lifetime at 105°C and ROHS3 compliance. UPW2C2R2MED is a Nichicon part (same manufacturer as the original, obsolete series). SEK2R2M160ST is a Cornell Dubilier Electronics part with active production status. SEK2R2M160ST is preferred for new designs due to active availability.

Q: Can I substitute the obsolete UVZ2C2R2MEH with an active part?

A: Yes. SEK2R2M160ST (Cornell Dubilier Electronics) is the recommended active substitute for direct replacement. For upgraded performance and extended lifetime, 200LLE2.2MEFC6.3X11 or 250LLE2.2MEFC6.3X11 (Rubycon LLE series) are preferred. All maintain electrical compatibility and improve reliability.

Q: What is the ripple current specification, and does it affect substitution?

A: The original UVZ2C2R2MEH specifies 25 mA at 120 Hz (low frequency) and 37.5 mA at 10 kHz (high frequency). Direct equivalents (UPW2C2R2MED, SEK2R2M160ST) specify 25 mA at 120 Hz and 40 mA at 10 kHz, which is compatible. Rubycon substitutes specify 36 mA at 120 Hz, also compatible. Ripple current specifications are within acceptable ranges for general-purpose applications.

Q: Is the ESR (Equivalent Series Resistance) specification important for substitution?

A: ESR is not specified for the original UVZ2C2R2MEH or most substitutes. SEK2R2M160ST specifies 90.47 Ohm at 120 Hz. For general-purpose applications, ESR differences are not a limiting factor in substitution. If ESR is critical to your application, consult detailed datasheets.
