Engineering Selection Recommendations

For Direct Replacement (Same Specifications)

UVR2W4R7MPD1AA is the primary recommendation. It maintains identical electrical and mechanical specifications as the original UVR2W4R7MPD while holding active product status, ensuring continued manufacturer support and supply availability.

ESMG451ELL4R7MJ20S (Chemi-Con) and 475CKS450MLN (Cornell Dubilier) are functionally equivalent alternatives with active status. Both meet all core electrical parameters and physical dimensions. ESMG451ELL4R7MJ20S provides slightly higher ripple current capability (56 mA @ 120 Hz), while 475CKS450MLN offers enhanced ripple current performance (70 mA @ 120 Hz) with a reduced height profile (14.00 mm vs. 22.00 mm).

For Enhanced Thermal Performance

450BXC4R7M10X20 and 450BXC4.7MEFC10X20 (Rubycon BXC series) extend lifetime to 10,000 hours at 105°C while maintaining the original 22.00 mm height and all electrical specifications. These are suitable for applications requiring improved reliability without PCB layout modifications.

450LLE4.7MEFC10X20 (Rubycon LLE series) provides the highest lifetime rating at 20,000 hours at 105°C with enhanced ripple current capability (66 mA @ 120 Hz). This option is appropriate for critical applications demanding extended service life.

For Extended Operating Temperature Range

ECA-2WHG4R7 (Panasonic NHG-A series) extends the maximum operating temperature to 105°C while maintaining the original 22.00 mm height. This option is suitable for applications in elevated ambient temperature environments.

All recommended substitutes are ROHS3 compliant and carry REACH unaffected status, maintaining regulatory compliance with the original part.

Frequently Asked Questions (FAQ)

Q: Can UVK2W4R7MPD be used as a direct replacement for UVR2W4R7MPD?

A: UVK2W4R7MPD meets all electrical specifications (4.7 µF, 450 V, ±20% tolerance) and lead spacing (5.00 mm). However, its height is reduced to 14.00 mm compared to the original 22.00 mm. This part is suitable only if the PCB layout accommodates the shorter profile. Both parts carry "Not For New Designs" status.

Q: What is the difference between 475CKS450M and 475CKS450MLN?

A: Both are Cornell Dubilier CKS series capacitors with identical electrical specifications. The primary difference is height: 475CKS450M measures 0.689" (17.50 mm), while 475CKS450MLN measures 0.551" (14.00 mm). Selection depends on available PCB space. 475CKS450MLN offers higher ripple current at low frequency (70 mA @ 120 Hz vs. 75 mA @ 120 Hz for the standard variant).

Q: Are the Rubycon BXC series parts (450BXC4R7M10X20 and 450BXC4.7MEFC10X20) identical?

A: Both Rubycon BXC series parts share identical electrical and mechanical specifications, including 10,000-hour lifetime at 105°C and 22.00 mm height. They are functionally interchangeable.

Q: Which substitute offers the best long-term reliability?

A: 450LLE4.7MEFC10X20 (Rubycon LLE series) provides the highest lifetime rating at 20,000 hours at 105°C. This part is recommended for applications requiring extended service intervals and maximum reliability.

Q: Can I use a substitute with a different height if my PCB has space?

A: Yes, provided the lead spacing (5.00 mm) and diameter (10.00 mm) remain compatible with the PCB footprint. Verify that the substitute's height does not interfere with adjacent components or enclosure constraints.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitutes carry RoHS3 compliance and REACH unaffected status, maintaining regulatory alignment with the original UVR2W4R7MPD.

Q: What is the significance of ripple current ratings in selecting a substitute?

A: Ripple current capacity determines the capacitor's ability to handle AC current superimposed on DC voltage. Higher ripple current ratings indicate better performance in high-frequency switching applications. Substitutes with equal or higher ripple current ratings are suitable for the original application.
