Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated at higher voltage than the original specification is electrically compatible. The UVR2F100MPD operates at 315 V, so substitutes rated at 350 V, 400 V, or 450 V are acceptable. Higher voltage ratings provide additional safety margin in the circuit.

Q: What is the significance of the lifetime rating difference between UVR and UCS series? A: The UVR series is rated for 2000 Hrs @ 85°C, while the UCS series is rated for 8000 Hrs @ 105°C. The UCS series provides four times longer operational life and maintains performance at higher temperatures. For applications requiring extended service life, UCS series substitutes are preferred.

Q: Are there mechanical constraints when substituting parts with different heights? A: Yes. The original UVR2F100MPD has a maximum seated height of 0.866". Substitutes with heights of 0.846" or 0.689" are mechanically compatible and will fit in the same PCB footprint. However, verify that the application does not have height restrictions that would prevent use of taller components.

Q: Why is the UVR2F100MPD marked as Not For New Designs? A: This designation indicates the part has been superseded in Nichicon's product lifecycle. For new designs, Active-status alternatives such as UCS2V100MPD or ESMG351ELL100MJ20S are recommended. Legacy designs may continue using UVR2F100MPD if inventory is available.

Q: What is the difference between Bulk and Tape & Box packaging? A: Bulk packaging is supplied in loose quantities suitable for high-volume manufacturing. Tape & Box packaging is supplied on tape reels in boxes, optimized for automated assembly equipment. Both packaging types contain identical components; selection depends on manufacturing process requirements.

Q: Can I substitute a Chemi-Con part for a Nichicon part? A: Yes. ESMG351ELL100MJ20S and ESMG401ELL100MJ20S from Chemi-Con meet all electrical and mechanical specifications for substitution. Different manufacturers produce capacitors to the same industry standards. Verify that your application does not have manufacturer-specific requirements before substituting.

Q: What does ROHS3 compliance mean? A: ROHS3 compliance indicates the component meets the Restriction of Hazardous Substances Directive, restricting lead, cadmium, mercury, and other hazardous materials. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory standards.
