Substitute Part Grouping Explanation

Substitution of the UVR2V220MHA is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Compatibility Parameters:

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

Allowable Substitution Criteria:

Voltage Rating: Equal to or greater than 350 V
Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C
Physical Dimensions: Lead spacing and mounting footprint must be identical; diameter and height may vary within PCB layout constraints
Ripple Current: Equal to or greater than specified values at corresponding frequencies

Substitute parts are grouped into three categories: direct equivalents (same voltage rating), and upgrades (higher voltage rating or extended temperature range). All listed substitutes maintain identical capacitance, tolerance, polarization, and through-hole radial package configuration.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating): UVR2V220MHD is the direct equivalent from Nichicon, maintaining 350 V rating and identical electrical specifications. This part is ROHS3 compliant and carries "Not For New Designs" status, making it suitable for legacy system support and replacement inventory only.

Upgrade Options (Higher Voltage Rating): Parts rated at 400 V or 450 V provide increased voltage margin above the original 350 V specification. These upgrades are recommended for new designs and ongoing procurement due to active product status and full ROHS3 compliance.

Active Product Alternatives: 226KFM400M, EKMG401ELL220MK25S, EKMQ401ELL220MK25S, EKXF451ELL220MK25S, ESG226M400AL4AA, ESMG401ELL220MK25S, ESMQ401ELL220MK25S, and MAL214262296E3 are all classified as active products with ROHS3 compliance. These parts satisfy substitution criteria and are available for new designs.

Physical Dimension Considerations: ESG226M400AL4AA has a slightly larger diameter (0.512" vs. 0.492") and requires PCB layout verification. EKMG401ELL220MK25S, EKMQ401ELL220MK25S, and EKXF451ELL220MK25S have reduced height (1.043" vs. 1.063"), which may provide space advantages in constrained layouts.

Temperature and Lifetime Performance: ULD2W220MHD and EKXF451ELL220MK25S offer extended lifetime (20000 Hrs @ 105°C) compared to the original specification (2000 Hrs @ 85°C), providing enhanced reliability for demanding applications. 226KFM400M delivers 10000 Hrs @ 105°C, and MAL214262296E3 provides 2500 Hrs @ 105°C.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V or 450 V rated capacitor in place of the 350 V UVR2V220MHA? A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters match: 22 µF capacitance, ±20% tolerance, polar configuration, radial can package, 0.197" lead spacing, and through-hole mounting. The higher voltage rating provides additional safety margin.

Q: What is the difference between direct equivalents and upgrades? A: Direct equivalents maintain the original 350 V rating (UVR2V220MHD). Upgrades feature higher voltage ratings (400 V or 450 V) and typically offer extended operating temperature ranges and longer lifetime specifications. Upgrades are suitable for new designs; direct equivalents are for legacy system support.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance. The original UVR2V220MHA is RoHS non-compliant, making compliant substitutes necessary for applications requiring RoHS certification.

Q: Does the slight height difference in some parts affect compatibility? A: Lead spacing and diameter are the critical PCB footprint parameters. EKMG401ELL220MK25S, EKMQ401ELL220MK25S, and EKXF451ELL220MK25S have reduced height (1.043" vs. 1.063"), which may provide layout advantages but requires verification that the reduced height does not conflict with component placement or clearance requirements.

Q: Which substitute offers the best long-term reliability? A: ULD2W220MHD and EKXF451ELL220MK25S both specify 20000 Hrs @ 105°C lifetime, providing the highest reliability rating among available substitutes. These parts are suitable for applications requiring extended service life and elevated temperature operation.

Q: Can I mix different substitute parts in the same circuit? A: Yes, provided each part meets the substitution criteria for the specific circuit location. All listed substitutes maintain identical capacitance, tolerance, and package configuration. Verify that voltage rating and temperature specifications are appropriate for each application point.

Q: What is the inventory status of these substitutes? A: All substitute parts listed are available in stock quantities ranging from 722 to 18198 pieces. Verify current availability with your component supplier before finalizing procurement decisions.
