Engineering Selection Recommendations

Direct Mechanical Compatibility (Lead Spacing 0.138" / 4.60 mm, Case Diameter 0.315" / 8.00 mm):

The UVY2G2R2MPD, 400LEX2.2MEFC8X9, and 400LLE2R2MEFC8X9 maintain identical lead spacing and case diameter, ensuring direct PCB footprint compatibility. These parts accept higher voltage ratings (400 V), which is electrically acceptable for 250 V applications. The UVY2G2R2MPD is a Nichicon product from the same manufacturer, classified as "Not For New Designs." The Rubycon alternatives (400LEX2.2MEFC8X9 and 400LLE2R2MEFC8X9) offer extended lifetime ratings (4000 and 12000 hours respectively) and are also classified as "Not For New Designs."

Alternative Mechanical Compatibility (Smaller Form Factor):

The EKMG251ELL2R2MF11D (Chemi-Con), MAL214232283E3, MAL214252283E3, MAL214272283E3 (Vishay), and SEK2R2M250ST (Cornell Dubilier) feature reduced lead spacing (0.098" / 2.50 mm) and smaller case diameter (0.248" / 6.30 mm). These parts require PCB redesign and are not direct drop-in replacements. All are classified as "Active" products, indicating current availability and suitability for new designs.

Compliance Status:

All listed substitute parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can UVY2G2R2MPD be used as a direct replacement for UPW2E2R2MPD?

A: Yes, mechanically and electrically. The UVY2G2R2MPD maintains identical lead spacing (0.138" / 4.60 mm) and case diameter (0.315" / 8.00 mm), allowing direct PCB mounting. The 400 V rating exceeds the 250 V requirement. However, the UVY2G2R2MPD is classified as "Not For New Designs," limiting its use to legacy system maintenance.

Q: What is the difference between 400LEX2.2MEFC8X9 and 400LLE2R2MEFC8X9?

A: Both are Rubycon 400 V, 2.2 µF capacitors with identical mechanical dimensions. The 400LLE2R2MEFC8X9 offers significantly extended lifetime (12000 hours @ 105°C versus 4000 hours @ 125°C), making it suitable for applications requiring higher reliability. Both maintain mechanical compatibility with the original part.

Q: Why do some alternatives have different lead spacing?

A: Parts with 0.098" (2.50 mm) lead spacing represent smaller form factors from alternative manufacturers. These require PCB redesign and cannot be used as direct drop-in replacements. Selection depends on available PCB space and design flexibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's environmental compliance status.

Q: Which substitute part is recommended for new designs?

A: The EKMG251ELL2R2MF11D (Chemi-Con), MAL214232283E3, MAL214252283E3, MAL214272283E3 (Vishay), and SEK2R2M250ST (Cornell Dubilier) are all classified as "Active" products. Selection among these depends on mechanical fit requirements and lead spacing compatibility with your PCB layout.
