UVR1HR47MDD Equivalent & Substitute Parts

Part Overview

The UVR1HR47MDD is a 0.47 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring polar capacitance. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible specifications.

Substitute Part Grouping Explanation

Substitute parts for the UVR1HR47MDD are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Capacitance value: 0.47 µF (exact match required)
Voltage rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package type: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)

Substitutes are grouped into two categories:

Parametric Equivalent: Parts with identical electrical specifications and physical dimensions, differing only in manufacturer or series designation.

Similar Substitute: Parts with identical core electrical specifications but reduced lifetime rating or modified physical dimensions that remain compatible with the original application footprint.

Engineering Selection Recommendations

515D474M050JA6AE3 (Vishay Sprague): This part is a parametric equivalent to the UVR1HR47MDD, matching all electrical specifications and physical dimensions exactly. Both components share identical 2000-hour lifetime ratings at 85°C and are ROHS3 compliant. This substitute is suitable for direct replacement in applications where the original Nichicon UVR series is no longer available.

UML1HR47MDD (Nichicon): This part is an active substitute from Nichicon's ML series. It maintains identical electrical specifications and operating temperature range but features a reduced lifetime rating of 1000 hours at 85°C compared to the original 2000 hours. Additionally, the UML1HR47MDD has smaller physical dimensions (0.157" diameter, 6.00mm height) and tighter lead spacing (0.059" versus 0.079"), which may require PCB layout verification. This substitute is appropriate for applications where component size reduction is beneficial and the reduced lifetime is acceptable for the intended service life.

Frequently Asked Questions (FAQ)

Q: Can the UML1HR47MDD be used as a direct replacement for the UVR1HR47MDD?

A: The UML1HR47MDD is electrically compatible but has physical dimension differences. The smaller case size (0.157" diameter vs. 0.197") and reduced lead spacing (0.059" vs. 0.079") require verification that the PCB footprint accommodates these changes. The reduced lifetime rating (1000 hours vs. 2000 hours at 85°C) must be evaluated against application requirements.

Q: Is the 515D474M050JA6AE3 a direct replacement?

A: Yes. The 515D474M050JA6AE3 matches the UVR1HR47MDD in all electrical parameters, physical dimensions, and lifetime rating. It is suitable for direct substitution without PCB layout modifications.

Q: What are the key differences between the substitute parts?

A: The primary differences are manufacturer (Nichicon vs. Vishay Sprague), product status (active vs. obsolete), and in the case of the UML1HR47MDD, physical size and lifetime rating. All three parts share identical capacitance, voltage rating, tolerance, and operating temperature specifications.

Q: Does the reduced ripple current rating of the UML1HR47MDD affect compatibility?

A: The UML1HR47MDD has lower ripple current ratings (4 mA @ 120 Hz, 6 mA @ 10 kHz) compared to the original (6.2 mA @ 120 Hz, 12.4 mA @ 10 kHz). Applications with high ripple current demands must verify that the UML1HR47MDD meets thermal and performance requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts—UVR1HR47MDD, UML1HR47MDD, and 515D474M050JA6AE3—are ROHS3 compliant.
