UVR2G220MHA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2G220MHA is a 22 µF, 400 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 parts necessary for ongoing production and maintenance applications. The UVR series has been superseded by newer product lines with improved performance characteristics and compliance ratings.

Substitute Part Grouping Explanation

Substitution for the UVR2G220MHA is determined by the following critical parameters: capacitance value (22 µF), voltage rating (minimum 400 V), tolerance (±20%), polarization (polar), lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole radial mounting configuration.

Substitute parts are grouped into two categories:

Direct Equivalents maintain the original 400 V voltage specification and 2000-hour lifetime rating. These parts are pin-compatible and dimensionally identical, requiring no circuit modifications.

Upgrade Substitutes feature higher voltage ratings (450 V) and extended lifetime ratings (4000–10000 hours at elevated temperatures). These parts provide enhanced performance margins and improved reliability while maintaining mechanical and electrical compatibility with the original footprint.

Engineering Selection Recommendations

For Direct Replacement (400 V, 2000 Hr Rating):

URS2G220MHD6 is the primary active equivalent from Nichicon. This part maintains the original electrical specifications while offering ROHS3 compliance and active product status. The reduced height (0.846" vs. 1.063") may provide space advantages in compact layouts while maintaining identical lead spacing and case diameter.

UVR2G220MHD remains available but carries "Not For New Designs" status, limiting its suitability for new production despite ROHS3 compliance.

For Enhanced Performance (450 V, Extended Lifetime):

226KFM450M (Cornell Dubilier / Illinois Capacitor) provides the highest lifetime rating at 10000 hours at 105°C with active product status and full ROHS3 compliance. The 450 V rating provides additional voltage margin over the original 400 V specification.

MAL215257229E3 and MAL215267229E3 (Vishay) offer 450 V ratings with 4000-hour lifetimes at 105°C and carry AEC-Q200 automotive qualification. Both maintain active product status and ROHS3 compliance.

All substitute parts maintain identical lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole radial mounting configuration, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can URS2G220MHD6 be used as a direct replacement for UVR2G220MHA?

A: Yes. URS2G220MHD6 maintains identical capacitance (22 µF), voltage rating (400 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (0.295" / 7.50 mm), and case diameter (0.630" / 16.00 mm). The reduced height (0.846" vs. 1.063") does not affect electrical performance and may provide layout benefits.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (URS2G220MHD6, UVR2G220MHD) maintain the original 400 V voltage and 2000-hour lifetime specifications. Upgrade substitutes (226KFM450M, MAL215257229E3, MAL215267229E3) feature higher voltage ratings (450 V) and extended lifetimes (4000–10000 hours at elevated temperatures), providing improved performance margins and reliability.

Q: Are all substitute parts RoHS compliant?

A: The original UVR2G220MHA is RoHS non-compliant. All listed substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for new production.

Q: Do the upgrade substitutes require circuit modifications?

A: No. All substitute parts maintain the same lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole radial mounting configuration. The higher voltage rating (450 V) and extended lifetime are backward-compatible with the original 400 V circuit design.

Q: Which substitute offers the best long-term reliability?

A: 226KFM450M provides the highest lifetime rating at 10000 hours at 105°C with active product status. MAL215257229E3 and MAL215267229E3 offer 4000-hour lifetimes at 105°C with AEC-Q200 automotive qualification.
