UVR2F010MEA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2F010MEA is a 1 µF, 315 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts maintain the same capacitance and tolerance while offering improved voltage ratings, extended lifetime specifications, and active product status from current manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Capacitance: Must be 1 µF (exact match required)
• Tolerance: Must be ±20% (exact match required)
• Voltage Rating: Must be equal to or greater than 315 V
• Polarization: Must be Polar (exact match required)
• Lead Spacing: Must be 0.098" (2.50mm) (exact match required)
• Size / Dimension: Must be 0.248" Dia (6.30mm) (exact match required)
• Mounting Type: Must be Through Hole (exact match required)
• Package / Case: Must be Radial, Can (exact match required)

All four substitute parts meet these criteria. The substitute parts are offered by active manufacturers (Rubycon and Chemi-Con) with improved voltage ratings (350 V or 400 V) and extended lifetime specifications, providing enhanced reliability compared to the obsolete UVR2F010MEA.

Parameter Comparison

Engineering Selection Recommendations

ESMQ401ELL1R0MF11D (Chemi-Con SMQ Series) and ESMG351ELL1R0MF11D (Chemi-Con SMG Series) are direct functional replacements with identical lifetime specifications (2000 Hrs @ 85°C) and operating temperature range (-40°C ~ 85°C) as the original UVR2F010MEA. Both are ROHS3 compliant and active products. ESMQ401ELL1R0MF11D provides 400 V rating, while ESMG351ELL1R0MF11D provides 350 V rating.

400LEX1MEFC6.3X11 (Rubycon LEX Series) offers enhanced reliability with 4000 hours lifetime at 125°C and extended operating temperature range to 125°C. This part is ROHS3 compliant and active. Height is 0.512" (13.00mm), which is 0.020" taller than the original.

400LLE1MEFC6.3X11 (Rubycon LLE Series) provides the longest lifetime specification at 12000 hours at 105°C with extended operating temperature range to 105°C. This part is ROHS3 compliant and active. Height is 0.512" (13.00mm), which is 0.020" taller than the original.

All substitute parts are ROHS3 compliant, addressing the non-compliance status of the obsolete UVR2F010MEA. Selection should be based on application requirements for operating temperature range, lifetime expectations, and PCB layout constraints regarding the slight height increase in Rubycon options.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 315 V UVR2F010MEA?

A: Yes. A higher voltage rating is a valid substitution. The 400 V rated parts (ESMQ401ELL1R0MF11D and both Rubycon options) will function in circuits designed for 315 V operation.

Q: What is the significance of the height difference between substitute parts?

A: The Rubycon LEX and LLE series parts are 0.512" (13.00mm) tall compared to 0.492" (12.50mm) for the original and Chemi-Con options. This 0.020" difference must be verified against PCB layout and enclosure clearance constraints before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts are ROHS3 compliant. The original UVR2F010MEA is RoHS non-compliant.

Q: Which substitute part should I select for maximum reliability?

A: Selection depends on application operating temperature. For applications operating at or below 85°C, ESMQ401ELL1R0MF11D or ESMG351ELL1R0MF11D are suitable. For applications requiring extended temperature operation or longer lifetime, 400LLE1MEFC6.3X11 (12000 Hrs @ 105°C) provides the highest rated lifetime.

Q: Are the lead spacing and mounting footprint identical across all parts?

A: Lead spacing is identical at 0.098" (2.50mm) for all parts. Diameter is identical at 0.248" (6.30mm). Height varies: original and Chemi-Con parts are 0.492" (12.50mm); Rubycon parts are 0.512" (13.00mm).

Q: Can I use ESMG351ELL1R0MF11D instead of ESMQ401ELL1R0MF11D?

A: Yes, both are Chemi-Con products with identical lifetime and operating temperature specifications. ESMG351ELL1R0MF11D has 350 V rating while ESMQ401ELL1R0MF11D has 400 V rating. Selection depends on circuit voltage requirements.
