UVZ2F220MHD Equivalent & Substitute Parts

Part Overview

The UVZ2F220MHD is a 22 µF, 315 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the product portfolio. The part delivers 2000 hours of operational life at 105°C and is suitable for general-purpose applications requiring polar capacitive filtering.

Locating equivalent and substitute parts is necessary due to the product's discontinued status for new designs. Alternative components with matching or enhanced electrical characteristics and improved lifecycle ratings are available from both Nichicon and other qualified manufacturers.

Voltage rating: Equal to or greater than 315 V
Lead spacing: 0.197" (5.00 mm) (exact match required)
Case diameter: 0.492" (12.50 mm) (exact match required)
Mounting type: Through Hole Radial (exact match required)
Polarization: Polar (exact match required)

Secondary Enhancement Parameters:

Lifetime @ 105°C: Equal to or greater than 2000 hours
Ripple current capability: Equal to or greater than specified values
Operating temperature range: -40°C ~ 105°C (exact match required)

Substitute parts are grouped into two categories: Upgrade substitutes (enhanced lifetime or voltage rating with identical mechanical footprint) and Similar substitutes (equivalent electrical performance with different product status).

Engineering Selection Recommendations

Direct Upgrade Path (Nichicon Ecosystem):

UCS2G220MHD and UCS2V220MHD represent the primary upgrade path from UVZ2F220MHD. Both parts maintain identical mechanical footprint compatibility (lead spacing 5.00 mm, case diameter 12.50 mm) while delivering significantly extended operational life (10000 hours at 105°C versus 2000 hours). Both are Active products suitable for new designs. UCS2G220MHD provides 400 V rating with enhanced ripple current handling; UCS2V220MHD provides 350 V rating, matching the original voltage class more closely.

Voltage-Rated Alternatives:

For applications requiring exact 315 V rating preservation, UPW2F220MHD offers 7000-hour lifetime at 105°C but carries Obsolete status and exhibits increased height (25.00 mm versus 22.00 mm), potentially creating PCB layout conflicts. This part is not recommended for new designs.

Cross-Manufacturer Options:

Rubycon 350PX22MEFC12.5X20 and 400PX22MEFC12.5X20 maintain identical mechanical dimensions and 2000-hour lifetime matching the original part's thermal endurance. Both are Active products. The 450BXW22MEFR12.5X20 variant extends voltage rating to 450 V with 10000-hour lifetime, providing maximum design margin.

Chemi-Con EKMQ351ELL220MK20S and Vishay MAL214262295E3 provide 350 V alternatives with Active status. Both maintain mechanical compatibility with minor height variations (21.50 mm and 22.00 mm respectively).

Compliance Considerations:

All substitute parts listed maintain ROHS3 compliance. UCY2V220MHD3 carries REACH Affected status; all other alternatives are REACH Unaffected. Selection should account for supply chain compliance requirements specific to end-use geography and application.

Frequently Asked Questions (FAQ)

Q: Can UCS2G220MHD directly replace UVZ2F220MHD in existing designs?

A: Yes, with verification. UCS2G220MHD maintains identical lead spacing (5.00 mm) and case diameter (12.50 mm). Height difference is minimal (21.50 mm versus 22.00 mm), typically accommodated by standard PCB clearances. The 400 V rating exceeds the original 315 V requirement, providing additional design margin. Electrical performance is superior across all ripple current specifications.

Q: What is the significance of the height variation between substitute parts?

A: Height variations (21.50 mm, 22.00 mm, 25.00 mm) directly impact PCB layout and component clearance. Parts with 21.50 mm height (UCS2G220MHD, UCS2V220MHD, UCY2V220MHD3, EKMQ351ELL220MK20S) fit within tighter vertical constraints. The original UVZ2F220MHD at 22.00 mm is compatible with most standard through-hole designs. UPW2F220MHD at 25.00 mm may require layout modification and is not recommended for new designs.

Q: How does lifetime rating affect component selection?

A: Lifetime rating (hours at 105°C) indicates thermal endurance. The original UVZ2F220MHD specifies 2000 hours. Substitutes offering 7000, 10000, or 12000 hours provide extended operational life under sustained thermal stress, reducing field failure risk in high-temperature environments. Selection depends on application thermal profile and reliability requirements.

Q: Are there mechanical compatibility concerns with cross-manufacturer substitutes?

A: All listed substitutes maintain the required lead spacing (5.00 mm) and case diameter (12.50 mm) for direct PCB footprint compatibility. Height variations are minor and typically accommodated by standard clearance design. Verify specific PCB layout constraints before final selection.

Q: Which substitute offers the best overall performance upgrade?

A: UCS2G220MHD and UCS2V220MHD from Nichicon provide the most comprehensive upgrades, combining Active product status, extended 10000-hour lifetime, enhanced ripple current capability, and identical mechanical footprint. Selection between them depends on voltage margin requirements: UCS2G220MHD (400 V) for maximum headroom, UCS2V220MHD (350 V) for voltage-class matching.

Q: What compliance certifications should be verified for supply chain requirements?

A: All substitutes maintain ROHS3 compliance. Most are REACH Unaffected; UCY2V220MHD3 is REACH Affected. Verify compliance status against specific end-use geography and customer requirements before procurement.
