UVZ2G4R7MPD Equivalent & Substitute Parts

Part Overview

The UVZ2G4R7MPD is a 4.7 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designated as Not For New Designs. Due to its obsolescence status and limited operational lifetime, equivalent and substitute parts from active manufacturers or with extended operational ratings are necessary for new circuit designs and long-term reliability requirements.

Engineering Selection Recommendations

For Direct Replacement (Same Lifetime): SEK4R7M400ST from Cornell Dubilier Electronics is the primary recommendation. This part maintains the 2000-hour lifetime specification of the original UVZ2G4R7MPD while offering Active product status, ensuring continued availability and supply chain support. All mechanical and electrical parameters are compatible with the original design.

For Enhanced Reliability (Extended Lifetime): 400LLE4R7MEFC10X12.5 from Rubycon and ULD2G4R7MPD from Nichicon both provide 15000-hour lifetime ratings at 105°C, representing a 7.5× improvement over the original specification. Both parts maintain identical capacitance, voltage, tolerance, and package dimensions. The Rubycon part offers Active status, while the Nichicon part is Not For New Designs.

EKXE401ELL4R7MJ16S from Chemi-Con provides 12000-hour lifetime with Active status and enhanced ripple current handling (225 mA @ 100 kHz), suitable for high-ripple applications.

For Automotive Applications: MAL215256478E3 from Vishay carries AEC-Q200 qualification and Active status, with 3000-hour lifetime and automotive-grade reliability. This part is suitable for automotive circuit designs requiring qualified components.

For Higher Voltage Margin: MAL214267478E3 from Vishay provides 450 V rating (50 V margin above the original 400 V specification) with Active status and 2500-hour lifetime, offering additional safety margin in high-voltage applications.

Parts to Avoid for New Designs: UVZ2G4R7MPD, UVY2G4R7MPD, and ULD2G4R7MPD are all designated Not For New Designs. UPW2G4R7MPD is Obsolete and should not be used. EKMG401ELL4R7MJ16S, while Active, has only 1000-hour lifetime, below the original specification.

All recommended substitutes are ROHS3 compliant and maintain the -40°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than 400 V? A: Yes. Parts rated at 450 V or higher are electrically compatible and provide additional safety margin. The MAL214267478E3 (450 V) is a valid substitute. Higher voltage ratings do not degrade performance in 400 V applications.

Q: What is the impact of different lifetime ratings on substitution? A: Lifetime rating indicates operational hours at 105°C before capacitance degradation exceeds tolerance limits. Parts with equal or greater lifetime are direct substitutes. Extended lifetime parts (5000+ hours) provide improved reliability and longer service life. Parts with shorter lifetime (EKMG401ELL4R7MJ16S at 1000 hours) are not recommended as they fall below the original 2000-hour specification.

Q: Are there mechanical constraints when substituting parts with different heights? A: Yes. The original UVZ2G4R7MPD has a maximum seated height of 0.689" (17.50 mm). Substitute parts with smaller heights (ULD2G4R7MPD at 0.571", UVY2G4R7MPD at 0.551") fit within the same PCB footprint. Parts with greater heights (UPW2G4R7MPD at 0.787") require verification of available clearance. All substitutes maintain the same 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) case diameter.

Q: What does "Not For New Designs" mean? A: This designation indicates the manufacturer is discontinuing the product line. While existing stock may be available, the part will not receive design updates or long-term supply guarantees. New designs should use Active status parts to ensure future availability and support.

Q: How do ripple current ratings affect part selection? A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings provide design margin for high-frequency switching applications. The original UVZ2G4R7MPD handles 50 mA @ 120 Hz and 80 mA @ 10 kHz. Substitutes with equal or greater ripple current are compatible. EKXE401ELL4R7MJ16S offers significantly higher ripple current (225 mA @ 100 kHz) for demanding applications.

Q: What is the significance of RoHS compliance? A: All listed substitutes are ROHS3 compliant, meeting European Union restrictions on hazardous substances. This ensures compatibility with modern manufacturing standards and regulatory requirements across global markets.

Q: Can I substitute with a part from a different manufacturer? A: Yes. All listed substitutes from Rubycon, Chemi-Con, KEMET, Cornell Dubilier Electronics, and Vishay are electrically and mechanically compatible when core parameters match (capacitance, voltage, tolerance, package type, lead spacing). Manufacturer selection may depend on supply availability, cost, and specific application requirements.

Q: Is ESR (Equivalent Series Resistance) important for substitution? A: ESR affects impedance and heat generation in high-frequency applications. The original UVZ2G4R7MPD does not specify ESR. ESG475M400AH2AA specifies 4.6 Ohm @ 100 kHz, and MAL215256478E3 specifies 18 Ohms. Lower ESR is beneficial for high-ripple applications. If ESR is critical to your design, verify the substitute part's specification against your circuit requirements.
