Key Parameters

Substitute Part Grouping Explanation

Substitution of the UEP0J470MDD is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 47 µF (exact match required)
• Tolerance: ±20% (matching tolerance band)
• Polarization: Bi-Polar (electrical characteristic)
• Lead spacing: 0.079" (2.00mm) (PCB compatibility)
• Physical dimensions: 0.197" Dia (5.00mm) and height 0.492" (12.50mm) (form factor compatibility)
• Mounting type: Through Hole (assembly process compatibility)
• Package type: Radial, Can (mechanical fit)

Allowable Variation:

• Voltage rating: The substitute part may have a higher rated voltage (16 V vs. 6.3 V) while maintaining all other parameters. A higher voltage rating provides additional design margin without affecting circuit performance in applications rated for 6.3 V operation.

The identified substitute maintains identical capacitance, tolerance, temperature range, lifetime specification, and physical form factor while offering an upgraded voltage rating and active product status.

Engineering Selection Recommendations

The 16NXA47MEFC5X11 (Rubycon NXA series) is the qualified substitute for the obsolete UEP0J470MDD. Selection is based on the following engineering criteria:

Compliance & Status:

• The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the original part.
• Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent environmental and hazardous substance classifications.

Electrical Equivalence:

• Capacitance and tolerance values are identical (47 µF ±20%), ensuring circuit performance remains unchanged.
• Operating temperature range (-55°C to 105°C) and lifetime specification (1000 Hrs @ 105°C) are identical, maintaining thermal performance characteristics.
• The 16 V rated voltage of the substitute exceeds the 6.3 V requirement of the original design, providing additional voltage margin without affecting circuit operation.

Mechanical Compatibility:

• Physical dimensions, lead spacing, and mounting configuration are identical, enabling direct PCB-level substitution without layout modifications.
• Both parts are through-hole radial can packages with matching form factors.

The substitute part is suitable for direct replacement in applications originally designed for the UEP0J470MDD.

Frequently Asked Questions (FAQ)

Q: Can the 16NXA47MEFC5X11 be used as a direct replacement for the UEP0J470MDD?

A: Yes. The substitute part matches all critical electrical parameters (capacitance, tolerance, temperature range, lifetime) and mechanical parameters (lead spacing, physical dimensions, mounting type, package configuration). Direct PCB substitution is possible without circuit redesign or layout modification.

Q: Why does the substitute part have a higher voltage rating (16 V vs. 6.3 V)?

A: A higher voltage rating does not affect circuit performance in applications designed for 6.3 V operation. The substitute provides additional design margin and improved reliability under voltage stress conditions. This is a standard engineering practice for component substitution.

Q: Are there any compatibility concerns with the substitute part?

A: No compatibility concerns exist. Both parts are bi-polar aluminum electrolytic capacitors with identical capacitance, tolerance, temperature range, and physical form factor. The substitute maintains ROHS3 and REACH compliance status.

Q: What is the advantage of using the 16NXA47MEFC5X11 over the original UEP0J470MDD?

A: The primary advantage is product status. The substitute is classified as Active, ensuring ongoing availability and supply chain support. The original part is Obsolete, creating procurement risk and potential long-term supply constraints.

Q: Are the ripple current specifications identical?

A: Ripple current at 120 Hz is identical (54 mA). Ripple current at 10 kHz differs slightly (108 mA vs. 81 mA), with the substitute showing lower high-frequency ripple current, which is a favorable characteristic for thermal performance.

Q: Can this substitute be used in new designs?

A: Yes. The 16NXA47MEFC5X11 is an Active product suitable for new design implementations. It meets all electrical and mechanical requirements for general-purpose aluminum electrolytic capacitor applications requiring 47 µF capacitance at 6.3 V or lower operating voltages.
