Substitute Part Grouping Explanation

Substitution of the UVR2V4R7MPD is determined by the following criteria:

Mandatory Parameters (Must Match):

Capacitance: 4.7 µF
Tolerance: ±20%
Package Type: Radial, Can
Lead Spacing: 0.197" (5.00 mm)
Case Diameter: 0.394" (10.00 mm)
Mounting Type: Through Hole
Polarization: Polar

Allowable Variations (Substitution Permitted):

Voltage Rating: 350 V or higher (400 V substitutes are acceptable as they provide higher voltage margin)
Operating Temperature Range: -40°C to 85°C or wider (e.g., -40°C to 105°C or -40°C to 125°C)
Lifetime @ Temperature: 2000 Hrs @ 85°C or longer
Height - Seated (Max): 0.551" (14.00 mm) or 0.571" (14.50 mm) are both acceptable within mechanical envelope constraints
RoHS Status: ROHS3 Compliant (all substitutes meet this requirement)

Substitute parts are grouped into two categories:

Category 1: Direct Voltage Upgrade (350 V → 400 V) Parts with 400 V rating provide enhanced voltage margin while maintaining identical capacitance, tolerance, and footprint. These are suitable for applications where the original 350 V rating is marginal or where design margin improvement is desired.

Category 2: Enhanced Reliability (Extended Lifetime & Temperature Range) Parts with extended lifetime ratings (5000 Hrs @ 125°C, 15000 Hrs @ 105°C) or wider operating temperature ranges (-40°C to 105°C or -40°C to 125°C) provide improved long-term performance and thermal stability.

Engineering Selection Recommendations

For Direct Replacement with Minimal Design Changes: Select 400PK4.7MEFC10X12.5 (Rubycon) or ESMQ401ELL4R7MJC5S (Chemi-Con). Both maintain identical physical dimensions (0.551" height), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C) as the original UVR2V4R7MPD, with the benefit of 400 V voltage rating. Both parts carry Active product status.

For Enhanced Reliability in Thermal Environments: Select 400LLE4R7MEFC10X12.5 (Rubycon) or ULD2G4R7MPD (Nichicon). These parts provide 15000 Hrs @ 105°C lifetime rating and extended operating temperature range to 105°C, suitable for applications requiring improved long-term stability. Note: ULD2G4R7MPD carries "Not For New Designs" status; 400LLE4R7MEFC10X12.5 is preferred as it is Active.

For Maximum Temperature Performance: Select 400LEX4.7MEFC10X12.5 (Rubycon). This part offers the highest operating temperature range (-40°C to 125°C) and extended lifetime (5000 Hrs @ 125°C), suitable for high-temperature applications. This part is Active and ROHS3 compliant.

For New Designs: Avoid parts marked "Not For New Designs" (UVR2V4R7MPD, ULD2G4R7MPD). Select from Active status parts: Rubycon 400 series (LEX, LLE, PK, PX variants) or Chemi-Con EKMQ/ESMQ series.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 350 V UVR2V4R7MPD? A: Yes. A 400 V capacitor is a valid substitute. Higher voltage rating provides additional safety margin and does not degrade circuit performance. All substitute parts listed carry 400 V rating.

Q: What is the difference between the Rubycon PK and PX series? A: Both are 4.7 µF, 400 V, ±20% tolerance radial capacitors. The PK series is rated 2000 Hrs @ 85°C with operating range -40°C to 85°C. The PX series is rated 2000 Hrs @ 105°C with operating range -40°C to 105°C. Select PX for applications requiring extended temperature operation.

Q: Are there height differences between substitute parts? A: Yes. The original UVR2V4R7MPD has a maximum seated height of 0.551" (14.00 mm). Some substitutes (ULD2G4R7MPD, 400LEX4.7MEFC10X12.5, 400LLE4R7MEFC10X12.5, 400PX4R7M10X12.5, 400PX4R7MEFCT810X12.5) have a maximum seated height of 0.571" (14.50 mm). Verify PCB layout clearance before selection.

Q: What does "Not For New Designs" mean? A: This status indicates the part is obsolete or superseded. Manufacturers recommend using alternative parts for new product development. Existing designs may continue using these parts if inventory permits, but new designs should select from Active status alternatives.

Q: Which substitute offers the best long-term reliability? A: The Rubycon 400LLE4R7MEFC10X12.5 provides 15000 Hrs @ 105°C lifetime rating, the highest among all listed substitutes. This part is suitable for applications requiring extended service life in moderate thermal environments.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status, meeting current environmental and regulatory requirements.

Q: Can I interchange Rubycon and Chemi-Con parts? A: Yes, provided electrical and mechanical parameters match. Rubycon 400PK4.7MEFC10X12.5 and Chemi-Con ESMQ401ELL4R7MJC5S are functionally equivalent (4.7 µF, 400 V, ±20%, 2000 Hrs @ 85°C, 0.551" height). Verify with your procurement and quality teams for any supplier qualification requirements.

Q: What is the lead spacing for all these parts? A: All parts, including the original UVR2V4R7MPD and all substitutes, have a lead spacing of 0.197" (5.00 mm) and case diameter of 0.394" (10.00 mm). PCB footprints are identical.
