Engineering Selection Recommendations

Direct Substitutes (Identical Specifications and Packaging):

UVR1V221MPD1TD is a direct substitute available in Tape & Box packaging instead of Bulk. All electrical and mechanical parameters are identical. This part maintains the same series designation and performance characteristics, differing only in packaging format.

Upgrade Substitutes (Enhanced Performance):

UFW1V221MPD, UKW1V221MPD, and UHE1V221MPD6 are Nichicon alternatives with identical core specifications (220 µF, 35 V, ±20%, through-hole radial can) but with enhanced performance characteristics. UHE1V221MPD6 offers extended lifetime (7000 hours at 105°C versus 2000 hours at 85°C) and wider operating temperature range (-40°C to 105°C). UPW1V221MPD provides 5000 hours at 105°C with extended lower temperature operation (-55°C to 105°C). These upgrades are suitable for applications requiring improved thermal stability and extended service life.

517D227M035CC6AE3 (Vishay Sprague) is an upgrade substitute with identical mechanical dimensions and electrical ratings but extended lifetime at elevated temperature (2000 hours at 105°C). This part is classified as Obsolete, limiting its availability for new procurement.

Cross-Manufacturer Alternatives:

ECA-1HM221 and ECA-1HM221B (Panasonic Electronic Components) are Active products with 50 V voltage rating, providing voltage margin above the 35 V requirement. These parts have identical lead spacing and case diameter but slightly increased height (0.531" versus 0.492"). Both are ROHS3 compliant and available in Bulk and Tape & Box packaging respectively.

Similar Substitutes (Minor Dimensional Variation):

UVK1V221MPD is a Nichicon alternative with identical electrical specifications but different mechanical dimensions: 0.138" lead spacing (versus 0.197"), 0.315" case diameter (versus 0.394"), and 0.512" height (versus 0.492"). This part is suitable only for applications where PCB layout accommodates the smaller footprint.

Compliance and Availability Considerations:

All recommended substitutes are ROHS3 compliant. UHE1V221MPD6 is REACH Affected; all others are REACH Unaffected. Product status varies: Nichicon UFW, UKW, UPW, and UVK series are Not For New Designs; Panasonic ECA-1HM series is Active; Vishay 517D series is Obsolete. For new designs, Panasonic ECA-1HM221 or ECA-1HM221B are preferred due to Active status.

Frequently Asked Questions (FAQ)

Q: Can UVR1V221MPD1TD replace UVR1V221MPD directly?

A: Yes. UVR1V221MPD1TD is a direct electrical and mechanical equivalent. The only difference is packaging format: UVR1V221MPD1TD is supplied in Tape & Box (TB) format while UVR1V221MPD is supplied in Bulk. Both maintain identical 220 µF capacitance, 35 V rating, ±20% tolerance, and through-hole radial can dimensions.

Q: What is the difference between the Nichicon upgrade options?

A: UFW1V221MPD and UKW1V221MPD maintain the same 2000-hour lifetime at 85°C as the original UVR1V221MPD. UHE1V221MPD6 extends lifetime to 7000 hours at 105°C and operating temperature to -40°C ~ 105°C. UPW1V221MPD provides 5000 hours at 105°C with extended lower temperature operation to -55°C. Selection depends on thermal environment and required service life.

Q: Can I use ECA-1HM221 in place of UVR1V221MPD?

A: ECA-1HM221 is electrically compatible (220 µF, ±20% tolerance, through-hole radial can) but has a higher voltage rating (50 V versus 35 V) and slightly increased height (0.531" versus 0.492"). The higher voltage rating provides design margin. Height difference must be verified against PCB clearance constraints. ECA-1HM221 is an Active Panasonic product, making it preferable for new designs.

Q: Why is UVK1V221MPD listed as a similar substitute rather than direct substitute?

A: UVK1V221MPD has different mechanical dimensions: lead spacing of 0.138" (versus 0.197"), case diameter of 0.315" (versus 0.394"), and height of 0.512" (versus 0.492"). While electrical specifications are identical, these dimensional differences require PCB layout verification before substitution.

Q: What is the status of 517D227M035CC6AE3?

A: 517D227M035CC6AE3 (Vishay Sprague) is classified as Obsolete. While it meets all electrical and mechanical specifications for the UVR1V221MPD, its obsolete status limits availability. This part should be considered only when other alternatives are unavailable and existing inventory can be sourced.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes are ROHS3 compliant. UHE1V221MPD6 is REACH Affected; all other substitutes are REACH Unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: Which substitute is recommended for new designs?

A: ECA-1HM221 or ECA-1HM221B (Panasonic Electronic Components) are recommended for new designs due to Active product status. Both provide 50 V voltage rating with identical lead spacing and case diameter. ECA-1HM221B in Tape & Box packaging is suitable for automated assembly processes.
