Nichicon UVR2V100MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2V100MPD is a 10 µF, 350 V aluminum electrolytic capacitor in radial, can package with through-hole mounting. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The UVR series offers a 2000-hour lifetime at 85°C with general-purpose applications across industrial and consumer electronics. Finding equivalent or substitute parts is necessary when UVR2V100MPD inventory is unavailable or when design requirements call for improved performance characteristics such as extended lifetime, higher voltage ratings, or enhanced ripple current handling.

Engineering Selection Recommendations

Primary Recommendation: UCS2V100MPD (Nichicon)

The UCS2V100MPD is the direct upgrade path from the UVR2V100MPD within the Nichicon product family. It maintains identical capacitance, voltage rating, tolerance, and mechanical dimensions while offering 8000-hour lifetime at 105°C compared to 2000 hours at 85°C. The UCS2V100MPD carries Active product status and is ROHS3 compliant, making it suitable for new designs. The extended operating temperature range (-40°C ~ 105°C) provides additional thermal margin.

Alternative Recommendation: UVR2V100MPD1AA (Nichicon)

The UVR2V100MPD1AA is a parametric equivalent within the same UVR series, offering identical electrical specifications and mechanical dimensions. It carries Active product status, addressing the obsolescence concern of the original part while maintaining backward compatibility in existing designs.

Higher Voltage Upgrade: UCS2G100MPD (Nichicon)

For applications requiring voltage margin, the UCS2G100MPD provides 400 V rating with identical capacitance and mechanical form factor. It offers the same 8000-hour lifetime at 105°C as the UCS2V100MPD with extended temperature range.

Cross-Manufacturer Alternatives:

ESMG351ELL100MJ20S (Chemi-Con) and ESMG401ELL100MJ20S (Chemi-Con) provide direct electrical equivalents with Active product status and ROHS3 compliance. The ESMG351ELL100MJ20S matches the 350 V rating; ESMG401ELL100MJ20S offers 400 V upgrade capability.

Extended Lifetime Option: EKXF451ELL100MJ20S (Chemi-Con)

For applications demanding maximum reliability, the EKXF451ELL100MJ20S provides 450 V rating with 20000-hour lifetime at 105°C. Mechanical dimensions remain compatible (0.394" diameter, 0.846" height). This part is suitable for long-life industrial applications.

Vishay Alternatives: MAL214231095E3, MAL214251095E3, MAL214261096E3

Vishay parts maintain the 10 µF capacitance, ±20% tolerance, and 0.394" case diameter. MAL214231095E3 and MAL214251095E3 offer 350 V rating with 2500-hour lifetime at 105°C. MAL214261096E3 provides 400 V rating. These parts feature reduced height (0.689" or 0.866") compared to the original UVR2V100MPD (0.866"), which may affect PCB layout compatibility.

Selection Criteria Summary:

Same-manufacturer continuity: UCS2V100MPD or UVR2V100MPD1AA
Voltage upgrade with extended life: UCS2G100MPD or EKXF451ELL100MJ20S
Cross-manufacturer compatibility: ESMG351ELL100MJ20S or ESMG401ELL100MJ20S

All recommended substitutes are ROHS3 compliant and carry Active product status.

Frequently Asked Questions (FAQ)

Q: Can I use UCS2G100MPD (400 V) in place of UVR2V100MPD (350 V)?

A: Yes. The UCS2G100MPD maintains identical capacitance (10 µF), tolerance (±20%), mechanical dimensions (0.394" diameter, 0.846" height), and lead spacing (5.00 mm). The higher voltage rating (400 V vs. 350 V) provides additional voltage margin and does not create compatibility issues. The UCS2G100MPD is electrically and mechanically interchangeable.

Q: What is the difference between UCS2V100MPD and UVR2V100MPD?

A: Both parts share identical electrical specifications: 10 µF, 350 V, ±20% tolerance. The primary differences are product status (UCS2V100MPD is Active; UVR2V100MPD is Not For New Designs), lifetime (8000 Hrs @ 105°C vs. 2000 Hrs @ 85°C), and operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C). Mechanical dimensions are nearly identical with minor height variation (0.846" vs. 0.866").

Q: Are Chemi-Con ESMG parts direct replacements?

A: ESMG351ELL100MJ20S and ESMG401ELL100MJ20S are direct electrical and mechanical equivalents. Both maintain 10 µF capacitance, ±20% tolerance, 0.394" case diameter, and 5.00 mm lead spacing. ESMG351ELL100MJ20S matches the 350 V rating; ESMG401ELL100MJ20S provides 400 V upgrade. Both are ROHS3 compliant and carry Active product status.

Q: Why is the Vishay MAL214231095E3 shorter than the original part?

A: The MAL214231095E3 has a seated height of 0.689" compared to the UVR2V100MPD's 0.866". This reduced height may affect PCB layout and component spacing. Verify clearance in your design before substitution. The electrical specifications remain identical.

Q: Can I use EKXF451ELL100MJ20S (450 V) in a 350 V circuit?

A: Yes. The EKXF451ELL100MJ20S is electrically and mechanically compatible. The 450 V rating exceeds the 350 V requirement, providing voltage margin. The 20000-hour lifetime at 105°C offers superior reliability compared to the original 2000-hour specification. Mechanical dimensions are compatible (0.394" diameter, 0.846" height, 5.00 mm lead spacing).

Q: What does "Not For New Designs" mean for the UVR2V100MPD?

A: This designation indicates the part has been superseded in the manufacturer's product portfolio. While existing inventory may be available, Nichicon recommends using active alternatives such as UCS2V100MPD or UVR2V100MPD1AA for new designs. Active parts receive ongoing support and are guaranteed to remain in production.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitutes listed carry ROHS3 compliance status, meeting environmental and regulatory requirements for electronics manufacturing.

Q: How do I verify mechanical compatibility before substitution?

A: Compare three critical dimensions: case diameter (0.394" / 10.00 mm required), lead spacing (0.197" / 5.00 mm required), and seated height. Most substitutes maintain the 0.394" diameter and 5.00 mm lead spacing. Height variations (0.689" to 0.866") may affect PCB layout. Verify clearance above and below the component location.
