Substitute Part Grouping Explanation

Substitution for the UVR2AR47MDA is determined by strict equivalence across the following critical parameters: capacitance value (0.47 µF), voltage rating (100 V), tolerance (±20%), lead spacing (0.079" / 2.00 mm), package diameter (0.197" / 5.00 mm), and mounting type (through hole, radial can). All substitute parts maintain these core electrical and mechanical specifications, ensuring direct compatibility in PCB layouts and circuit designs. Variations in lifetime rating, operating temperature ceiling, and RoHS compliance status are noted but do not prevent functional substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Direct Substitutes (Nichicon UVR Series): UVR2AR47MDD provides identical electrical and mechanical specifications to the UVR2AR47MDA with improved RoHS3 compliance. Both parts share the same series designation, capacitance, voltage rating, tolerance, and physical dimensions. The primary distinction is packaging format (bulk versus standard) and RoHS certification status.

Upgraded Tolerance Option (Nichicon UKL Series): UKL2AR47KDD offers tighter tolerance (±10% versus ±20%) while maintaining all core electrical and mechanical parameters. This part is suitable for applications requiring improved capacitance accuracy. Height is marginally reduced to 0.472" (12.00 mm) compared to 0.492" (12.50 mm), which may require PCB layout verification in space-constrained designs.

Active Product Alternatives: 474CKH100M (Cornell Dubilier / Illinois Capacitor) and 474CKR100M (Cornell Dubilier / Illinois Capacitor) are active products with identical capacitance, voltage, tolerance, and mechanical specifications. Both feature RoHS3 compliance and extended operating temperature ranges to 105°C. The 474CKH100M provides enhanced lifetime rating (2000 Hrs @ 105°C) and higher ripple current capability (12 mA @ 120 Hz, 27.6 mA @ 100 kHz).

Premium Long-Life Option: 100YXJ0.47M5X11 (Rubycon) is an active product with extended lifetime (5000 Hrs @ 105°C) and elevated operating temperature ceiling (-40°C ~ 105°C). This part is suitable for applications requiring enhanced reliability and thermal performance while maintaining full mechanical and electrical compatibility.

All substitute parts are RoHS3 compliant except the original UVR2AR47MDA, which is RoHS non-compliant. Selection should prioritize active products (474CKH100M, 474CKR100M, 100YXJ0.47M5X11) for new designs and long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can UVR2AR47MDD be used as a direct replacement for UVR2AR47MDA? A: Yes. UVR2AR47MDD is a direct substitute with identical capacitance (0.47 µF), voltage rating (100 V), tolerance (±20%), lead spacing (0.079" / 2.00 mm), package diameter (0.197" / 5.00 mm), and height (0.492" / 12.50 mm). The primary difference is RoHS3 compliance status.

Q: What is the difference between UKL2AR47KDD and UVR2AR47MDA? A: UKL2AR47KDD offers tighter tolerance (±10% versus ±20%) and is from the Nichicon UKL series. All other electrical and mechanical parameters are equivalent. Height is slightly reduced to 0.472" (12.00 mm), requiring PCB layout verification.

Q: Are Cornell Dubilier parts (474CKH100M, 474CKR100M) compatible with the original UVR2AR47MDA? A: Yes. Both Cornell Dubilier parts maintain identical capacitance, voltage rating, tolerance, lead spacing, package diameter, and mounting type. They are active products with RoHS3 compliance and extended operating temperature ranges to 105°C.

Q: What is the advantage of 100YXJ0.47M5X11 over the original part? A: The Rubycon 100YXJ0.47M5X11 is an active product with extended lifetime (5000 Hrs @ 105°C versus 2000 Hrs @ 85°C) and elevated operating temperature ceiling (-40°C ~ 105°C). It provides enhanced reliability for demanding applications while maintaining full mechanical and electrical compatibility.

Q: Do all substitute parts fit the same PCB footprint? A: All substitute parts share identical lead spacing (0.079" / 2.00 mm) and package diameter (0.197" / 5.00 mm). UKL2AR47KDD has a slightly reduced height (0.472" / 12.00 mm) compared to others (0.492" / 12.50 mm), which may require clearance verification in space-constrained layouts.

Q: Which substitute part should be selected for new designs? A: For new designs, prioritize active products: 474CKH100M, 474CKR100M, or 100YXJ0.47M5X11. All are RoHS3 compliant with extended operating temperature ranges and active product status, ensuring long-term availability and supply chain continuity.
