Engineering Selection Recommendations

Direct Upgrade Path (Nichicon Series): UVZ2V010MED is the primary upgrade from UVZ2F010MEH within the same manufacturer family. It maintains identical mechanical dimensions and electrical characteristics while providing a 35 V higher voltage rating (350 V vs. 315 V). Both parts are obsolete; however, UVZ2V010MED has significantly higher inventory availability (4630 units vs. 790 units).

Active Production Alternatives (Higher Voltage Rating): The 400 V rated parts (400LEX1MEFC6.3X11, 400LLE1MEFC6.3X11, 400PX1MEFC6.3X11, and EKMQ401ELL1R0MF11D) are all active production components from established manufacturers. These parts provide enhanced design margin through higher voltage rating and ROHS3 compliance. Selection among these four depends on application-specific requirements:

400LLE1MEFC6.3X11 (Rubycon): Offers the longest lifetime rating (12000 Hrs @ 105°C), suitable for applications requiring extended operational life.
400LEX1MEFC6.3X11 (Rubycon): Supports extended operating temperature to 125°C with 4000 Hrs @ 125°C lifetime, appropriate for high-temperature environments.
400PX1MEFC6.3X11 (Rubycon): Maintains baseline 1000 Hrs @ 105°C lifetime with active production status.
EKMQ401ELL1R0MF11D (Chemi-Con): Provides 400 V rating with active production status and ROHS3 compliance.

Mechanical Variation Consideration: 400 V rated Rubycon parts (LEX, LLE, PX series) have a maximum height of 0.512" (13.00 mm) compared to the original 0.492" (12.50 mm). This 0.020" (0.50 mm) increase must be evaluated against PCB layout constraints.

Similar Alternative (Different Lead Spacing): SEK010M350ST (Cornell Dubilier Electronics) is mechanically incompatible due to different lead spacing (0.138" vs. 0.098") and larger diameter (0.315" vs. 0.248"). This part is suitable only for applications where PCB layout can accommodate the larger footprint.

Compliance Consideration: All substitute parts except UVZ2V010MED are ROHS3 compliant. For applications subject to RoHS regulations, active production alternatives are required.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 315 V UVZ2F010MEH? A: Yes. Higher voltage ratings provide design margin and are electrically compatible. The 400 V rated parts (400LEX1MEFC6.3X11, 400LLE1MEFC6.3X11, 400PX1MEFC6.3X11, EKMQ401ELL1R0MF11D) are direct functional replacements. Verify PCB layout accommodates the slightly increased height (0.512" vs. 0.492").

Q: What is the difference between UVZ2V010MED and the 400 V alternatives? A: UVZ2V010MED is a Nichicon part with 350 V rating, maintaining the original manufacturer family and identical mechanical dimensions. The 400 V alternatives are from different manufacturers (Rubycon, Chemi-Con) with higher voltage rating and active production status. UVZ2V010MED is also obsolete, while 400 V alternatives are active.

Q: Why does 400LLE1MEFC6.3X11 have a much longer lifetime rating? A: 400LLE1MEFC6.3X11 is rated for 12000 Hrs @ 105°C compared to 1000 Hrs @ 105°C for most alternatives. This reflects different internal construction and electrolyte formulation, providing extended operational life for applications requiring higher reliability.

Q: Can I use SEK010M350ST as a substitute? A: SEK010M350ST is electrically compatible but mechanically incompatible. It has different lead spacing (0.138" vs. 0.098") and larger diameter (0.315" vs. 0.248"). Use only if PCB layout can be modified to accommodate the larger footprint.

Q: Are all substitute parts RoHS compliant? A: All substitute parts except UVZ2V010MED are ROHS3 compliant. For applications requiring RoHS compliance, select from active production alternatives: 400LEX1MEFC6.3X11, 400LLE1MEFC6.3X11, 400PX1MEFC6.3X11, or EKMQ401ELL1R0MF11D.

Q: What is the maximum height variation I should accept? A: The original UVZ2F010MEH has a maximum height of 0.492" (12.50 mm). Rubycon 400 V alternatives have a maximum height of 0.512" (13.00 mm), a 0.020" (0.50 mm) increase. Verify this fits within your PCB clearance and component placement constraints.

Q: Which substitute offers the best long-term availability? A: All 400 V rated parts (400LEX1MEFC6.3X11, 400LLE1MEFC6.3X11, 400PX1MEFC6.3X11, EKMQ401ELL1R0MF11D) are active production components. Among these, 400LLE1MEFC6.3X11 and 400LEX1MEFC6.3X11 from Rubycon offer the most extended operational ratings, supporting long-term design continuity.
