UVR2G220MHD Equivalent & Substitute Parts

Part Overview

The UVR2G220MHD is a 22 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as not for new designs, indicating it has been superseded in the product lifecycle. Finding equivalent and substitute parts is necessary for maintenance, repair, and legacy system support where original components may be unavailable or where design upgrades are required.

Substitute Part Grouping Explanation

Substitution of the UVR2G220MHD is determined by the following critical parameters:

Electrical Match: Capacitance (22 µF), voltage rating (400 V minimum), and tolerance (±20%)
Mechanical Compatibility: Lead spacing (0.295" / 7.50 mm), case diameter, and height must accommodate PCB layout and clearance requirements
Thermal Performance: Lifetime rating and operating temperature range must meet or exceed application demands
Compliance: RoHS3 compliance and through-hole mounting type

Substitutes are grouped into three categories:

Direct Equivalents maintain identical electrical and mechanical specifications with the same 400 V rating and 2000 Hrs @ 85°C lifetime.

Similar Parts match core electrical parameters and mechanical footprint but may have minor dimensional variations that remain compatible with standard PCB layouts.

Upgrade Parts provide enhanced performance through higher voltage ratings (450 V) or extended lifetime ratings (up to 10000 Hrs @ 105°C), suitable for applications requiring improved reliability or operating margin.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications)

URS2G220MHD6 and URS2G220MHD are active Nichicon products with identical electrical ratings to the UVR2G220MHD. Both maintain 22 µF capacitance, 400 V voltage rating, and 2000 Hrs @ 85°C lifetime. URS2G220MHD6 offers a reduced height of 0.846" (21.50 mm) compared to the original 1.063" (27.00 mm), providing improved PCB space efficiency while maintaining the same case diameter. URS2G220MHD has a larger case diameter of 0.709" (18.00 mm) with reduced height of 0.650" (16.50 mm). Both are ROHS3 compliant and suitable for general-purpose applications.

For Enhanced Reliability (Upgrade Path)

226KFM450M, MAL215257229E3, and MAL215267229E3 provide upgraded performance with 450 V voltage rating and extended lifetime ratings. The 226KFM450M offers 10000 Hrs @ 105°C with operating temperature range to 105°C, providing significant margin over the original specification.
