UVR2F220MPA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2F220MPA is a 22 µF, 315 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing design support and production continuity. The UVR series has been superseded by active product lines offering improved performance characteristics, extended operational temperature ranges, and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

Capacitance: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Voltage Rating Substitution Logic: Substitute parts must have a voltage rating equal to or greater than 315 V. Parts rated at 350 V, 400 V, or 450 V are electrically compatible and provide enhanced voltage margin.

Thermal and Lifetime Considerations: Substitute parts may have different lifetime ratings and maximum operating temperatures. Parts with extended lifetimes (10000 Hrs or 12000 Hrs) and higher temperature ratings (105°C) represent performance upgrades but remain functionally compatible.

Compliance Upgrades: Substitute parts with ROHS3 compliance represent regulatory improvements over the non-compliant original part.

Engineering Selection Recommendations

Direct Replacement (Same Thermal Profile): For applications requiring identical thermal characteristics to the UVR2F220MPA, select 350PK22MEFC12.5X20 or 400PK22MEFC12.5X20. Both maintain the 2000-hour lifetime at 85°C operating temperature and identical physical dimensions. These Rubycon parts provide ROHS3 compliance upgrade while preserving the original thermal specification.

Enhanced Performance Upgrade: For new designs or applications where thermal margin is beneficial, UCS2V220MHD (350 V, 10000 Hrs @ 105°C) or UCS2G220MHD (400 V, 10000 Hrs @ 105°C) provide extended operational lifetime and higher temperature capability. Both are Nichicon active products with ROHS3 compliance. Note: UCS2V220MHD and UCS2G220MHD have a maximum height of 0.846" (21.50 mm), which is 0.020" shorter than the original part.

Maximum Voltage Margin: 450BXW22MEFR12.5X20 offers the highest voltage rating (450 V) with extended 10000-hour lifetime at 105°C. This Rubycon part maintains the original 0.866" (22.00 mm) height and provides maximum electrical margin for demanding applications.

Multi-Manufacturer Availability: UCY2V220MHD3 (Nichicon, 350 V, 12000 Hrs @ 105°C) and EKMQ351ELL220MK20S (Chemi-Con, 350 V, 2000 Hrs @ 105°C) provide alternative sourcing options. UCY2V220MHD3 offers the longest rated lifetime at 12000 hours.

Compliance Consideration: All substitute parts listed are ROHS3 compliant, addressing the non-compliant status of the original UVR2F220MPA. This upgrade is mandatory for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 315 V UVR2F220MPA? A: Yes. A higher voltage rating provides additional electrical margin and is electrically compatible. The capacitor will operate safely at voltages up to its rated maximum. Voltage derating is not required for direct substitution.

Q: What is the significance of the height difference between 0.866" and 0.846"? A: The 0.020" height reduction in UCS2V220MHD and UCS2G220MHD will not affect most through-hole PCB layouts. Verify clearance in your specific application, particularly if the capacitor is mounted near tall components or in confined spaces.

Q: Are the Rubycon and Chemi-Con parts equivalent to Nichicon parts? A: Yes, within the specified electrical and mechanical parameters. All substitute parts maintain identical capacitance, tolerance, lead spacing, case diameter, and mounting type. Differences in manufacturer reflect alternative sourcing options with equivalent performance characteristics.

Q: Why do some parts have 2000-hour lifetimes while others have 10000 hours? A: Lifetime rating indicates the expected operational duration at the specified temperature. Parts with 10000-hour ratings provide extended service life and are suitable for applications requiring higher reliability. The original UVR2F220MPA has a 2000-hour rating; upgrades to 10000-hour parts are optional and application-dependent.

Q: What does ROHS3 compliance mean for my application? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. If your application or market requires RoHS compliance, all listed substitute parts satisfy this requirement, whereas the original UVR2F220MPA does not.

Q: Can I substitute a part with a different operating temperature range? A: Yes, if your application operates within the substitute part's temperature range. The original part operates from -40°C to 85°C. Substitute parts rated to 105°C maximum temperature provide additional thermal margin and are compatible with the original specification.

Q: Are ripple current ratings important for substitution? A: Ripple current capability is an application-specific consideration. If your circuit requires specific ripple current handling, verify the substitute part's ripple current rating matches or exceeds your requirement. This parameter is not a substitution barrier but an application validation criterion.
