Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 315 V UVR2F4R7MPD? A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters match. A 400 V capacitor provides additional voltage margin and is electrically compatible in circuits designed for 315 V operation.

Q: What is the significance of the height difference between 0.551" and 0.571"? A: The 0.020" (0.50 mm) height difference is within acceptable tolerance for through-hole PCB applications. Verify clearance in your specific board layout before substitution.

Q: Are Rubycon and Chemi-Con parts direct replacements for Nichicon? A: Yes, provided they match the mandatory parameters: 4.7 µF capacitance, ±20% tolerance, 400 V or higher rating, radial can package, 0.197" lead spacing, and 0.394" diameter. All listed substitutes meet these criteria.

Q: Why do some parts have different lifetime ratings at different temperatures? A: Lifetime ratings reflect the thermal stress on the capacitor at specific temperatures. Higher temperature ratings (105°C, 125°C) indicate better thermal stability. Parts rated for higher temperatures generally exhibit longer operational life.

Q: Which substitute offers the best long-term reliability? A: The 400LEX4.7MEFC10X12.5 (Rubycon) offers the highest thermal rating (125°C) and extended lifetime (5000 Hrs @ 125°C), providing superior long-term reliability in thermally demanding applications.

Q: Is the UVR2V4R7MPD (350 V variant) a suitable substitute? A: The UVR2V4R7MPD is electrically compatible but remains Not For New Designs status. For new applications, select an Active status part such as 400PK4.7MEFC10X12.5 or 400LLE4R7MEFC10X12.5.

Q: What does ROHS3 compliance mean for this application? A: ROHS3 compliance indicates the capacitor meets Restriction of Hazardous Substances Directive requirements, restricting lead, mercury, cadmium, and other hazardous materials. All listed substitutes are ROHS3 compliant.
