Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete UEP2AR47MDD is based on strict electrical and mechanical parameter matching:

Electrical Compatibility Criteria:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±20% (matching specification)
• Voltage rating: Equal to or greater than 100 V
• Lifetime: 1000 Hrs @ 105°C minimum
• Operating temperature range: -55°C ~ 105°C (full range coverage)
• Polarization: Bi-Polar

Mechanical Compatibility Criteria:

• Lead spacing: 0.079" (2.00 mm)
• Package diameter: 0.197" Dia (5.00 mm)
• Height - Seated (Max): 0.492" (12.50 mm)
• Mounting type: Through Hole
• Package / Case: Radial, Can

The substitute part 160NXA0.47MEFC5X11 meets all electrical and mechanical requirements, with the additional benefit of a higher voltage rating (160 V vs. 100 V), providing enhanced design margin.

Engineering Selection Recommendations

The 160NXA0.47MEFC5X11 (Rubycon NXA series) is the qualified substitute for the obsolete UEP2AR47MDD. Selection is based on the following engineering criteria:

Electrical Equivalence: All core electrical parameters match or exceed the original specification. The 160 V voltage rating provides additional design margin compared to the 100 V original rating, making this substitute suitable for applications where voltage headroom is beneficial.

Mechanical Compatibility: Footprint and mounting characteristics are identical, enabling direct PCB replacement without layout modifications.

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Product Status: The substitute part is active and in production, providing long-term availability and supply chain stability compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the 160NXA0.47MEFC5X11 be used as a direct replacement for the UEP2AR47MDD?

A: Yes. The substitute part matches all critical electrical and mechanical parameters. The higher voltage rating (160 V vs. 100 V) is compatible with circuits designed for 100 V operation and provides additional safety margin.

Q: Are there any PCB layout changes required when substituting to the 160NXA0.47MEFC5X11?

A: No. Lead spacing, package diameter, and height are identical. The component occupies the same footprint and requires no PCB modifications.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 160 V rating on the Rubycon part exceeds the original 100 V specification. This provides enhanced voltage margin and does not negatively impact circuit performance in applications designed for 100 V operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the UEP2AR47MDD and 160NXA0.47MEFC5X11 are ROHS3 compliant and REACH unaffected.

Q: Why is the original UEP2AR47MDD obsolete?

A: The UEP series has been discontinued by Nichicon. The 160NXA0.47MEFC5X11 from Rubycon's active NXA series provides equivalent functionality with current production support.

Q: Is the capacitance tolerance identical between the two parts?

A: Yes. Both parts specify ±20% tolerance, ensuring equivalent performance in tolerance-sensitive applications.
