Substitute Part Grouping Explanation

Substitution of the UVR2F470MHD is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Capacitance: 47 µF (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Size / Dimension: 0.630" Dia (16.00 mm) (exact match required)
Polarization: Polar (exact match required)

Voltage Rating Substitution Logic: Substitute parts must have a voltage rating equal to or greater than 315 V. Parts rated at 350 V, 400 V, or 450 V are acceptable as they provide equal or superior voltage withstand capability.

Operating Temperature & Lifetime: Substitute parts may have extended operating temperature ranges (-40°C ~ 105°C or -40°C ~ 125°C) and longer lifetimes (3000 Hrs, 10000 Hrs, or 12000 Hrs) compared to the original 2000 Hrs @ 85°C specification. These represent performance improvements and do not compromise compatibility.

Ripple Current: Substitute parts with equal or higher ripple current ratings are acceptable and provide improved performance margin.

Frequently Asked Questions (FAQ)

Q: Can I use a 350 V rated capacitor to replace the 315 V UVR2F470MHD? A: Yes. A 350 V rated capacitor provides adequate voltage margin above the original 315 V specification. Parts EKMG351ELL470ML25S, EKMQ351ELL470ML25S, and ESMG351ELL470ML25S are electrically compatible substitutes.

Q: What is the advantage of using UCS2G470MHD over the original UVR2F470MHD? A: UCS2G470MHD offers five times longer lifetime (10000 Hrs vs. 2000 Hrs), higher voltage rating (400 V vs. 315 V), extended operating temperature range (105°C vs. 85°C), and significantly higher ripple current capability (590 mA vs. 340 mA). It is an active product with assured long-term supply.

Q: Are all substitute parts mechanically identical to the UVR2F470MHD? A: Yes. All listed substitutes share identical lead spacing (0.295" / 7.50 mm), can diameter (0.630" / 16.00 mm), and radial through-hole mounting configuration. Direct PCB replacement is possible without layout changes.

Q: Which substitute offers the best thermal performance? A: EGXF401ELL470ML25S (Chemi-Con) operates to 125°C with 3000 Hrs lifetime, providing the highest temperature rating. For extended lifetime at elevated temperature, 450BXW47MEFR16X25 (Rubycon) offers 12000 Hrs @ 105°C.

Q: Can I use a higher voltage rated capacitor in my application? A: Yes. Capacitors rated at 350 V, 400 V, or 450 V are direct substitutes for the 315 V original part. Higher voltage ratings provide additional safety margin and do not affect circuit operation.

Q: What is the difference between Nichicon UAS2G470MHD and UCS2G470MHD? A: Both are 47 µF, 400 V Nichicon parts with identical mechanical form factor. UCS2G470MHD provides superior performance with 10000 Hrs lifetime at 105°C compared to UAS2G470MHD's 2000 Hrs @ 105°C. UCS2G470MHD also offers higher ripple current capability (590 mA vs. 290 mA @ 120 Hz).

Q: Are there RoHS compliance differences among the substitutes? A: All listed substitutes are RoHS compliant. EGXF401ELL470ML25S carries ROHS3 compliance with AEC-Q200 automotive qualification. Standard industrial substitutes (Nichicon UAS/UCS series, Rubycon PK/PX/BXW series, Chemi-Con KMG/KMQ/SMG series) are ROHS3 compliant.
