UVR2AR47MDD Equivalent & Substitute Parts

Part Overview

The UVR2AR47MDD is a 0.47 µF, 100 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 and energy storage.

Substitute Part Grouping Explanation

Substitution of the UVR2AR47MDD is determined by strict equivalence across the following critical parameters: capacitance value (0.47 µF), voltage rating (100 V), package geometry (radial can with 0.079" lead spacing, 5.00 mm diameter, 12.50 mm maximum height), mounting type (through hole), and polarization (polar). Tolerance variations and lifetime ratings at different temperatures are secondary considerations that do not prevent functional substitution when the primary electrical and mechanical parameters align.

The substitute parts are grouped as follows:

Upgrade Substitutes — Parts with improved specifications (tighter tolerance or extended lifetime) that maintain full compatibility:

UKL2AR47KDD (±10% tolerance, same lifetime)
100YXJ0.47M5X11 (extended 5000 Hrs @ 105°C lifetime)

Direct Equivalent — Part with identical electrical specifications and active product status:

474CKH100M (Cornell Dubilier / Illinois Capacitor, active status)

Parametric Equivalent — Part meeting all critical parameters with active status:

474CKR100M (Cornell Dubilier / Illinois Capacitor, active status)

Engineering Selection Recommendations

For applications requiring immediate component availability and long-term supply assurance, select from active-status parts: 100YXJ0.47M5X11 (Rubycon), 474CKH100M (Cornell Dubilier), or 474CKR100M (Cornell Dubilier). All three maintain full electrical and mechanical compatibility with the UVR2AR47MDD while offering current production status.

The 100YXJ0.47M5X11 provides the highest reliability margin with 5000-hour lifetime at 105°C and extended operating temperature range to 105°C, suitable for applications with elevated thermal stress or extended service life requirements.

The 474CKH100M and 474CKR100M are direct equivalents from Cornell Dubilier / Illinois Capacitor with active product status and ROHS3 compliance. Both maintain the same package footprint and electrical specifications as the original part.

For designs where tolerance improvement is beneficial without requiring extended lifetime, the UKL2AR47KDD (Nichicon, ±10% tolerance) offers tighter capacitance tolerance, though it remains classified as obsolete.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UKL2AR47KDD replace UVR2AR47MDD directly on the PCB?

A: Yes. The UKL2AR47KDD maintains identical lead spacing (0.079"), case diameter (0.197"), and maximum height (0.472"), ensuring direct through-hole compatibility. The ±10% tolerance is tighter than the original ±20%, providing improved capacitance accuracy.

Q: What is the primary difference between 474CKH100M and 474CKR100M?

A: Both parts are Cornell Dubilier / Illinois Capacitor equivalents with identical electrical specifications and package geometry. The 474CKH100M is rated for 2000 hours at 105°C, while 474CKR100M is rated for 2000 hours at 85°C. The 474CKH100M offers superior thermal performance for elevated-temperature applications.

Q: Why is 100YXJ0.47M5X11 classified as an upgrade substitute?

A: The 100YXJ0.47M5X11 extends the lifetime rating to 5000 hours at 105°C and supports operating temperatures to 105°C, compared to the original 2000 hours at 85°C. This provides enhanced reliability for thermally demanding applications while maintaining full electrical and mechanical compatibility.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitutes are through-hole radial can packages with 0.079" lead spacing, suitable for PCB mounting in the same footprint as the UVR2AR47MDD.

Q: Do the substitute parts meet current compliance standards?

A: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Can I use 100YXJ0.47M5X11 in a design rated for -40°C to 85°C operation?

A: Yes. The 100YXJ0.47M5X11 supports the full -40°C to 105°C operating range, which encompasses the original -40°C to 85°C specification. The extended temperature capability does not create compatibility issues in designs operating within the original temperature window.
