Nichicon UVR2DR47MEA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2DR47MEA is a 0.47 µF, 200 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 that requires identification of compatible alternatives meeting the same electrical and mechanical specifications or offering enhanced performance characteristics within the same form factor.

Substitute Part Grouping Explanation

Substitution of the UVR2DR47MEA is determined by strict equivalence in the following parameters: capacitance value (0.47 µF), tolerance (±20%), package type (radial, can), lead spacing (2.50 mm), case diameter (6.30 mm), and through-hole mounting configuration. Voltage rating and operating temperature range define the performance envelope and determine functional compatibility.

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

Category 1: Same Voltage (200 V) with Enhanced Thermal Performance

UPS2DR47MED: Maintains 200 V rating with extended operating temperature to 105°C and improved RoHS3 compliance

Category 2: Elevated Voltage (250 V and 400 V) with Same Thermal Performance

UVR2ER47MED: Increases voltage rating to 250 V while maintaining UVR series characteristics and RoHS3 compliance
UVK2GR47MED: Increases voltage rating to 400 V for applications requiring higher voltage margin

Category 3: Alternative Manufacturer (250 V)

250PK0.47MEFC6.3X11: Rubycon PK series equivalent with 250 V rating and active product status

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): UPS2DR47MED is the primary direct replacement, maintaining identical 200 V voltage rating and 0.47 µF capacitance while offering improved thermal performance with extended operating temperature to 105°C and ROHS3 compliance. This part is suitable for applications where the original UVR2DR47MEA specifications are required with enhanced reliability.

For Voltage Margin Applications: UVR2ER47MED provides a 250 V rated alternative within the Nichicon UVR series, offering 25% voltage headroom over the original 200 V specification. This part maintains identical physical dimensions and thermal characteristics while providing ROHS3 compliance.

UVK2GR47MED extends voltage rating to 400 V for applications requiring significant voltage margin or operating in higher voltage environments. Physical dimensions remain identical, enabling direct PCB compatibility.

For Active Product Status: 250PK0.47MEFC6.3X11 from Rubycon represents the only active product among the substitutes, offering 250 V rating and ROHS3 compliance. Height dimension is 0.512" (13.00 mm) compared to 12.50 mm for other options, requiring verification of available PCB clearance. This part is suitable for new designs requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can UPS2DR47MED replace UVR2DR47MEA in existing designs? A: Yes. UPS2DR47MED maintains the same 200 V voltage rating, 0.47 µF capacitance, ±20% tolerance, and identical physical dimensions (lead spacing, case diameter, height). The extended operating temperature range to 105°C and ROHS3 compliance represent improvements over the original specification.

Q: What is the difference between UVR2ER47MED and UVK2GR47MED? A: Both are Nichicon alternatives with identical physical dimensions. UVR2ER47MED provides 250 V rating (25% margin above original 200 V), while UVK2GR47MED provides 400 V rating (100% margin). Selection depends on circuit voltage requirements and design margin strategy.

Q: Is 250PK0.47MEFC6.3X11 compatible with the original PCB layout? A: Physical compatibility is confirmed for lead spacing (2.50 mm), case diameter (6.30 mm), and mounting type (through hole). Height dimension is 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the original part. Verify available vertical clearance on the PCB before substitution.

Q: Why is 250PK0.47MEFC6.3X11 recommended for new designs? A: This Rubycon part carries active product status, ensuring long-term availability and supply chain continuity. All other substitutes are classified as obsolete. ROHS3 compliance and 250 V rating support modern design requirements.

Q: Can I use a 400 V rated capacitor in a 200 V circuit? A: Yes. UVK2GR47MED with 400 V rating is electrically compatible in a 200 V circuit. The higher voltage rating provides additional safety margin and does not affect circuit performance when the applied voltage remains at or below 200 V.

Q: What are the ripple current differences between substitutes? A: Ripple current specifications vary by part. UPS2DR47MED and UVK2GR47MED specify lower ripple current (12 mA @ 120 Hz, 19.2 mA @ 10 kHz) compared to UVR2DR47MEA and UVR2ER47MED (15 mA @ 120 Hz, 24 mA @ 10 kHz). 250PK0.47MEFC6.3X11 specifies the lowest ripple current (8 mA @ 120 Hz, 12 mA @ 10 kHz). Selection should account for circuit ripple current requirements.
