UVR2ER47MED Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2ER47MED is a 0.47 µF 250 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The UVR series represents legacy technology; however, functionally equivalent alternatives exist within current and near-current product lines that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UVR2ER47MED is determined by strict equivalence in the following parameters: capacitance value (0.47 µF), tolerance (±20%), operating temperature range (-40°C ~ 85°C), polarization (polar), package type (radial, can), lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), and mounting type (through hole). Voltage rating may be equal or higher; lifetime at temperature must meet or exceed 2000 Hrs @ 85°C. All substitutes must maintain ROHS3 compliance.

Two substitute parts meet these criteria:

1. UVK2GR47MED (Nichicon) — Upgrade substitute with higher voltage rating (400 V vs. 250 V)
2. 250PK0.47MEFC6.3X11 (Rubycon) — Direct equivalent with identical voltage rating (250 V)

Parameter Comparison

Engineering Selection Recommendations

UVK2GR47MED (Nichicon UVK Series) is suitable for applications where higher voltage margin is acceptable. This upgrade substitute provides 400 V rating versus the original 250 V specification, offering increased safety margin in circuits with voltage transients or design headroom requirements. Both parts are Nichicon products with identical mechanical footprint and lead spacing. Product status is obsolete for both.

250PK0.47MEFC6.3X11 (Rubycon PK Series) provides direct electrical equivalence at the original 250 V rating. This part maintains active product status, ensuring long-term availability and supply chain continuity. The case height is 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the original; this 0.020" (0.50 mm) difference must be evaluated against PCB layout constraints and clearance requirements.

Both substitutes maintain identical capacitance, tolerance, temperature range, and lifetime specifications. Selection depends on voltage margin requirements and PCB height clearance availability.

Frequently Asked Questions (FAQ)

Q: Can UVK2GR47MED replace UVR2ER47MED in any application? A: Yes, within the original circuit voltage specification. The UVK2GR47MED operates at 400 V rating, which is compatible with circuits designed for 250 V operation. The higher voltage rating does not degrade performance in lower-voltage applications.

Q: What is the primary difference between the two substitutes? A: UVK2GR47MED offers higher voltage rating (400 V) and is manufactured by Nichicon. 250PK0.47MEFC6.3X11 maintains the original 250 V rating and is manufactured by Rubycon with active product status. The Rubycon part has a maximum height of 0.512" versus 0.492" for the Nichicon substitute.

Q: Are there mechanical compatibility concerns with 250PK0.47MEFC6.3X11? A: Lead spacing (0.098" / 2.50 mm) and case diameter (0.248" / 6.30 mm) are identical to the original part. The case height difference of 0.020" (0.50 mm) must be evaluated for PCB layout clearance, particularly in space-constrained designs.

Q: Do all three parts meet current compliance standards? A: Yes. UVR2ER47MED, UVK2GR47MED, and 250PK0.47MEFC6.3X11 are all ROHS3 compliant and REACH unaffected.

Q: Which substitute should be selected for new designs? A: 250PK0.47MEFC6.3X11 is recommended for new designs due to active product status, ensuring availability and supply chain support. UVK2GR47MED may be selected if higher voltage margin is a design requirement.
