UVR2F010MED Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2F010MED is a 1 µF, 315 V aluminum electrolytic capacitor in radial, can package configuration designed for general purpose applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The UVR series has been discontinued, requiring engineers to identify compatible alternatives that maintain electrical and mechanical compatibility within the application constraints.

Substitute Part Grouping Explanation

Substitution for the UVR2F010MED is determined by the following critical parameters: capacitance value (1 µF), tolerance (±20%), package configuration (radial, can through-hole), lead spacing (2.50 mm), and case diameter (6.30 mm). The voltage rating of 315 V establishes a minimum threshold; substitute parts must equal or exceed this rating to ensure safe operation within the original circuit design.

Four active substitute parts meet these mechanical and electrical criteria:

ESMQ401ELL1R0MF11D (Chemi-Con SMQ series): 1 µF, 400 V, identical case dimensions
ESMG351ELL1R0MF11D (Chemi-Con SMG series): 1 µF, 350 V, identical case dimensions
400LLE1MEFC6.3X11 (Rubycon LLE series): 1 µF, 400 V, slightly increased height (13.00 mm)
400LEX1MEFC6.3X11 (Rubycon LEX series): 1 µF, 400 V, slightly increased height (13.00 mm)

All substitute parts maintain the same lead spacing, case diameter, and through-hole mounting configuration. Voltage ratings of 350 V and 400 V provide margin above the original 315 V specification.

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current manufacturing standards. The Chemi-Con parts (ESMQ401ELL1R0MF11D and ESMG351ELL1R0MF11D) maintain the original height specification of 12.50 mm, providing direct mechanical compatibility without PCB layout modifications. The Rubycon parts (400LLE1MEFC6.3X11 and 400LEX1MEFC6.3X11) feature a 0.5 mm height increase to 13.00 mm, which may require verification of available vertical clearance in the application enclosure.

Voltage rating selection depends on circuit requirements: the 350 V ESMG351ELL1R0MF11D provides the minimum margin above the original 315 V specification, while the 400 V options (ESMQ401ELL1R0MF11D, 400LLE1MEFC6.3X11, 400LEX1MEFC6.3X11) offer additional safety margin. All substitute parts maintain identical lead spacing and case diameter, ensuring footprint compatibility on existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original UVR2F010MED?

A: Yes. The substitute parts rated at 350 V and 400 V are electrically compatible with circuits designed for 315 V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance.

Q: Are there mechanical compatibility concerns with the Rubycon parts?

A: The Rubycon 400LLE1MEFC6.3X11 and 400LEX1MEFC6.3X11 are 0.5 mm taller (13.00 mm vs. 12.50 mm) than the original part. Verify available vertical clearance in your application before selection. Lead spacing and case diameter remain identical.

Q: Do all substitute parts have the same lead spacing as the original?

A: Yes. All substitute parts maintain 0.098" (2.50 mm) lead spacing, ensuring direct compatibility with existing PCB footprints designed for the UVR2F010MED.

Q: Which substitute part provides the closest electrical match to the original?

A: The ESMG351ELL1R0MF11D (350 V) provides the closest voltage rating match above the original 315 V specification. The ESMQ401ELL1R0MF11D (400 V) offers additional voltage margin while maintaining identical case dimensions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference between the Chemi-Con SMQ and SMG series substitutes?

A: Both Chemi-Con parts (ESMQ401ELL1R0MF11D and ESMG351ELL1R0MF11D) maintain identical case dimensions and lead spacing. The primary difference is voltage rating: SMQ series at 400 V versus SMG series at 350 V. Both are active products with full availability.
