Equivalent & Substitute Parts for UVR2F220MHD

Part Overview

The Nichicon UVR2F220MHD 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with a rated lifetime of 2000 hours at 85°C. This part is classified as "Not For New Designs," indicating it has been superseded in Nichicon's product portfolio. Finding equivalent and substitute parts is necessary for applications requiring continued support, legacy system maintenance, or when the original part becomes unavailable. Substitute parts must maintain the same capacitance value, tolerance, physical dimensions, and lead spacing while potentially offering improved electrical performance or extended operational lifetime.

Substitute Part Grouping Explanation

Substitution for the UVR2F220MHD is determined by the following mandatory parameters:

Electrical Compatibility:

Capacitance value must equal 22 µF
Tolerance must be ±20%
Voltage rating must be equal to or greater than 315 V
Polarization must remain polar

Physical Compatibility:

Package type must be radial, can
Lead spacing must be 0.197" (5.00 mm)
Diameter must be 0.492" (12.50 mm)
Height must not exceed 0.866" (22.00 mm) to ensure PCB fit

Environmental Compatibility:

Operating temperature range must encompass -40°C to 85°C minimum

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Class):

No direct 315 V substitutes are available in the active product portfolio. The UVR2F220MHD operates at 315 V, and all substitute parts listed operate at 350 V or higher. This voltage increase is acceptable for applications designed for 315 V operation, as it provides additional electrical margin without affecting circuit functionality.

For Nichicon Ecosystem Continuity:

Nichicon UCS2V220MHD (350 V) and UCS2G220MHD (400 V) are recommended for applications requiring continued support within the Nichicon product family. Both parts are classified as Active and offer extended lifetime ratings (10000 hours at 105°C) compared to the original UVR2F220MHD (2000 hours at 85°C). The UCS2V220MHD maintains the 350 V voltage class with improved thermal performance, while UCS2G220MHD provides the highest voltage margin at 400 V.

For Extended Lifetime Requirements:

UCY2V220MHD3 (Nichicon, 350 V, 12000 Hrs @ 105°C) offers the longest rated lifetime among Nichicon substitutes and is suitable for applications requiring maximum operational reliability over extended service periods.

For Multi-Manufacturer Sourcing:

Rubycon 350PX22MEFC12.5X20 and 400PX22MEFC12.5X20 (PX series) provide cross-manufacturer alternatives with active product status. The 400PX variant offers 400 V rating with 2000 hours lifetime at 105°C. Rubycon 450BXW22MEFR12.5X20 provides the highest voltage rating (450 V) with extended lifetime (10000 hours at 105°C).

Chemi-Con EKMQ351ELL220MK20S (350 V) is available as a third-source alternative with active status and 2000 hours lifetime at 105°C.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. UCY2V220MHD3 is noted as REACH Affected; other parts are REACH Unaffected. Verify REACH compliance requirements for your specific application jurisdiction before final selection.

Frequently Asked Questions (FAQ)

Q: Can I use a 350 V or 400 V capacitor in place of the 315 V UVR2F220MHD?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. A 350 V or 400 V capacitor will function correctly in a circuit designed for 315 V operation and provides additional electrical safety margin. Physical dimensions and lead spacing must remain identical for PCB compatibility.

Q: What is the difference between the Nichicon UCS2V220MHD and UCS2G220MHD?

A: Both are Nichicon UCS series capacitors with 22 µF capacitance and ±20% tolerance. The UCS2V220MHD is rated at 350 V with 10000 hours lifetime at 105°C. The UCS2G220MHD is rated at 400 V with the same 10000 hours lifetime at 105°C. The 400 V rating provides greater electrical margin for applications with voltage transients or overvoltage conditions.

Q: Why do some substitute parts have different heights (0.846" vs. 0.866")?

A: Physical height variations within the same lead spacing and diameter are acceptable for through-hole radial capacitors. The UVR2F220MHD specifies a maximum height of 0.866" (22.00 mm). Substitute parts with 0.846" (21.50 mm) height are physically smaller and will fit within the same PCB footprint. Verify your PCB layout accommodates the specific height of your selected substitute.

Q: What does "Not For New Designs" mean for the UVR2F220MHD?

A: This product status indicates that Nichicon has discontinued the UVR series for new applications and recommends using active alternatives for new designs. Existing applications using UVR2F220MHD can continue operation, but new product development should transition to active series such as UCS or UCY.

Q: Are Rubycon and Chemi-Con substitutes fully compatible with Nichicon originals?

A: Yes, provided that capacitance, voltage rating, tolerance, physical dimensions, lead spacing, and operating temperature range are identical. All listed Rubycon and Chemi-Con substitutes meet these criteria. Cross-manufacturer substitution is standard practice in electronics manufacturing when electrical and mechanical parameters match.

Q: Which substitute offers the best lifetime rating?

A: The Nichicon UCY2V220MHD3 offers the longest rated lifetime at 12000 hours at 105°C. The Rubycon 450BXW22MEFR12.5X20 also provides 10000 hours at 105°C with the highest voltage rating (450 V). Selection depends on your application's voltage requirements and expected service life.

Q: Do I need to change my PCB layout to use a substitute part?

A: No. All substitute parts maintain the same lead spacing (0.197" / 5.00 mm) and diameter (0.492" / 12.50 mm). Height variations are minor and will not affect PCB layout. Verify that your PCB footprint accommodates the maximum height of your selected substitute.
