Nichicon UTT1C470MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UTT1C470MDD is a 47 µF, 16 V aluminum electrolytic capacitor in radial, can package rated for 5000 hours at 105°C. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The UTT series has been discontinued, requiring engineers to identify compatible alternatives that maintain electrical performance within the application's design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UTT1C470MDD is determined by the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: Minimum 16 V (equal or higher voltage rating acceptable)
• Tolerance: ±20% (standard tolerance for general purpose applications)
• Package Type: Radial, Can (mechanical compatibility with PCB layout)
• Mounting Type: Through Hole (for direct pin replacement)
• Operating Temperature: Minimum -40°C ~ 105°C range
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Two substitute categories are identified:

MFR Recommended Substitute: UPW1V470MED maintains the same capacitance and tolerance with upgraded voltage rating (35 V) and improved ripple current handling. This part is from the same manufacturer (Nichicon) and provides enhanced performance margins.

Similar Substitute: UCW1C470MCL1GS matches the original voltage rating (16 V) and capacitance but uses surface mount technology (SMD) instead of through-hole mounting, requiring PCB redesign for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: The Nichicon UPW1V470MED is the MFR recommended substitute. It maintains identical mechanical compatibility (lead spacing 2.50mm, radial can package, through-hole mounting) and electrical specifications (47 µF, ±20% tolerance). The higher voltage rating (35 V vs. 16 V) provides additional design margin without affecting circuit operation. Both parts are ROHS3 compliant. Note that UPW1V470MED is also classified as obsolete; however, it maintains higher inventory availability (20270 pcs vs. 1037 pcs for the original part).

For Active Product Status: The Nichicon UCW1C470MCL1GS is an active product offering long-term availability. It matches the original voltage rating (16 V) and capacitance (47 µF) with improved lifetime rating (7000 hrs vs. 5000 hrs at 105°C). However, this part requires surface mount assembly and cannot be used as a direct pin replacement without PCB redesign. Selection of this part is appropriate only when PCB layout modifications are feasible.

Frequently Asked Questions (FAQ)

Q: Can UPW1V470MED be used as a direct replacement for UTT1C470MDD?

A: Yes. Both parts are through-hole radial can packages with identical lead spacing (2.50mm), height (7.00mm), and diameter (6.30mm). The UPW1V470MED's higher voltage rating (35 V) is compatible with 16 V circuit designs and does not affect electrical performance.

Q: What is the difference between the MFR recommended and similar substitutes?

A: The UPW1V470MED (MFR recommended) is a through-hole part with direct mechanical compatibility. The UCW1C470MCL1GS (similar) is a surface mount device requiring PCB redesign. Both maintain the 47 µF capacitance and ±20% tolerance.

Q: Does the higher voltage rating of UPW1V470MED affect circuit operation?

A: No. A capacitor with higher voltage rating operates normally in lower voltage applications. The 35 V rating of UPW1V470MED provides additional safety margin in a 16 V circuit without changing electrical behavior.

Q: Why is UCW1C470MCL1GS listed as a similar substitute if it requires PCB changes?

A: UCW1C470MCL1GS is the only active (non-obsolete) Nichicon product matching the 47 µF, 16 V specifications. It is suitable for new designs or redesigns where surface mount assembly is acceptable. For existing through-hole designs, UPW1V470MED is the appropriate choice.

Q: Are all three parts ROHS3 compliant?

A: Yes. UTT1C470MDD, UPW1V470MED, and UCW1C470MCL1GS are all ROHS3 compliant, meeting current regulatory requirements.

Q: What is the inventory status for these parts?

A: UTT1C470MDD (1037 pcs), UPW1V470MED (20270 pcs), and UCW1C470MCL1GS (2672 pcs) are all listed as new original in stock. UPW1V470MED offers the highest inventory availability.
