UVR2ER47MEA Equivalent & Substitute Parts

Part Overview

The UVR2ER47MEA is a 0.47 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring polar capacitive filtering.

Substitute Part Grouping Explanation

Substitution eligibility for the UVR2ER47MEA is determined by the following critical parameters: capacitance value (0.47 µF), rated voltage (minimum 250 V), tolerance (±20%), polarization (polar), mounting type (through hole), and physical package compatibility (radial, can with 0.098" lead spacing). Parts meeting these core electrical and mechanical specifications are classified as direct substitutes. Parts with elevated voltage ratings (400 V) are classified as upgrades, providing enhanced voltage margin while maintaining all other electrical and mechanical compatibility criteria.

Engineering Selection Recommendations

UVR2ER47MED (Nichicon) is a direct substitute offering identical electrical and mechanical specifications with improved RoHS3 compliance status. This part maintains the same 250 V rating, 0.47 µF capacitance, and physical dimensions as the original UVR2ER47MEA.

UVK2GR47MED (Nichicon) is an upgrade substitute with a 400 V rated voltage, providing enhanced voltage margin for applications requiring additional safety headroom. All other electrical and mechanical parameters remain compatible with the original specification. RoHS3 compliance is provided.

250PK0.47MEFC6.3X11 (Rubycon) is a direct substitute from an alternative manufacturer with identical electrical specifications and RoHS3 compliance. Physical dimensions are compatible with a maximum seated height of 0.512" (13.00 mm), representing a 0.020" (0.50 mm) increase from the original specification. This part carries active product status.

Frequently Asked Questions (FAQ)

Q: Can UVR2ER47MED be used as a direct replacement for UVR2ER47MEA? A: Yes. UVR2ER47MED maintains identical capacitance (0.47 µF), voltage rating (250 V), tolerance (±20%), temperature range (-40°C to 85°C), and physical dimensions. The primary difference is improved RoHS3 compliance status.

Q: What is the difference between UVR2ER47MED and UVK2GR47MED? A: Both parts are manufactured by Nichicon with identical capacitance and physical dimensions. UVK2GR47MED provides a higher voltage rating of 400 V compared to 250 V in UVR2ER47MED. This upgrade is suitable for applications requiring additional voltage margin while maintaining full mechanical and thermal compatibility.

Q: Can the Rubycon 250PK0.47MEFC6.3X11 be used in place of the Nichicon UVR2ER47MEA? A: Yes, with consideration of physical height. The Rubycon part has a maximum seated height of 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the original. All electrical specifications, lead spacing, and polarization are compatible. Verify PCB layout clearance before implementation.

Q: Are all substitute parts RoHS compliant? A: UVR2ER47MED, UVK2GR47MED, and 250PK0.47MEFC6.3X11 are all ROHS3 compliant. The original UVR2ER47MEA is RoHS non-compliant.

Q: What are the ripple current differences among these parts? A: Ripple current specifications vary by manufacturer and voltage rating. UVR2ER47MEA and UVR2ER47MED both support 24 mA @ 10 kHz. UVK2GR47MED supports 19.2 mA @ 10 kHz. 250PK0.47MEFC6.3X11 supports 12 mA @ 10 kHz. Select based on application ripple current requirements.
