UVR2DR47MED Equivalent & Substitute Parts

Part Overview

The UVR2DR47MED is a 0.47 µF 200 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, serving general-purpose applications requiring polar capacitive filtering.

Substitute Part Grouping Explanation

Substitution eligibility for the UVR2DR47MED is determined by the following critical parameters: capacitance value (0.47 µF), tolerance (±20%), voltage rating (minimum 200 V), polarization (polar), package type (radial, can), lead spacing (0.098" / 2.50 mm), and through-hole mounting compatibility. Parts meeting these core electrical and mechanical specifications are functionally equivalent.

The substitute parts are grouped into three categories based on voltage rating and thermal performance:

Category 1 - Same Voltage (200 V): UPS2DR47MED offers improved thermal performance at 105°C operating temperature versus the original 85°C maximum, with identical voltage and capacitance ratings.

Category 2 - Elevated Voltage (250 V and 400 V): UVR2ER47MED (250 V) and UVK2GR47MED (400 V) provide higher voltage margins while maintaining the same capacitance and tolerance. These are suitable for applications where voltage headroom is beneficial.

Category 3 - Alternative Manufacturer: 250PK0.47MEFC6.3X11 (Rubycon) matches the 250 V voltage rating and core electrical specifications with active product status, though with slightly different physical height (0.512" versus 0.492").

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original UVR2DR47MED specification.

For direct replacement with identical thermal performance: UPS2DR47MED is the primary equivalent, offering the same voltage rating and physical dimensions while extending the maximum operating temperature to 105°C. This part remains obsolete but provides superior thermal margin.

For applications requiring voltage margin: UVR2ER47MED (250 V) or UVK2GR47MED (400 V) are suitable when circuit design permits higher voltage ratings. Both maintain identical physical footprint to the original part.

For active product availability: 250PK0.47MEFC6.3X11 (Rubycon) is the only active product among the substitutes. This part accommodates the same electrical specifications with a 0.020" (0.50 mm) height increase. Physical clearance verification is required for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can UPS2DR47MED replace UVR2DR47MED in all applications?

A: Yes. UPS2DR47MED maintains identical voltage rating (200 V), capacitance (0.47 µF), tolerance (±20%), and physical dimensions. The extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) provides additional thermal margin without affecting compatibility.

Q: What is the difference between UVR2ER47MED and UVK2GR47MED?

A: Both parts share identical capacitance, tolerance, and physical dimensions as the original UVR2DR47MED. The primary difference is voltage rating: UVR2ER47MED is rated 250 V while UVK2GR47MED is rated 400 V. Selection depends on circuit voltage requirements and design margin preferences.

Q: Can 250PK0.47MEFC6.3X11 be used as a direct drop-in replacement?

A: 250PK0.47MEFC6.3X11 is electrically equivalent with matching capacitance, tolerance, voltage rating (250 V), and lead spacing. The case height is 0.512" (13.00 mm) compared to 0.492" (12.50 mm) for the original part. Physical clearance in the PCB assembly must be confirmed before substitution.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts are through-hole mounted with 0.098" (2.50 mm) lead spacing, matching the original UVR2DR47MED package configuration.

Q: Which substitute part has active product status?

A: 250PK0.47MEFC6.3X11 (Rubycon) is the only active product. All Nichicon alternatives (UPS2DR47MED, UVR2ER47MED, UVK2GR47MED) are classified as obsolete.
