Nichicon UTT1E330MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UTT1E330MDD is a 33 µF, 25 V aluminum electrolytic capacitor in radial, can package with through-hole mounting. 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 and mechanical compatibility within the application constraints.

Substitute Part Grouping Explanation

Substitute parts for the UTT1E330MDD are identified based on the following criteria:

Primary Substitution Criteria:

• Capacitance value: 33 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting type: Through Hole (for direct PCB compatibility)
• Package type: Radial, Can (mechanical fit requirement)
• Lead spacing: 0.098" (2.50mm) (PCB footprint compatibility)
• Case diameter: 0.248" (6.30mm) (physical envelope constraint)
• Height: 0.276" (7.00mm) (board clearance requirement)

Secondary Considerations:

• Voltage rating: May be equal or higher than 25 V (derating acceptable)
• Operating temperature range: Must encompass application requirements
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Two substitute categories are identified:

1. Manufacturer Recommended Substitute (Higher Voltage Rating): UPW1H330MED — Same capacitance and tolerance with 50 V rating, higher ripple current capability, and improved lifetime specifications. Mounting type remains through-hole with identical lead spacing and case dimensions.

2. Similar Substitute (Same Voltage Rating, Different Mounting): UCW1E330MCL1GS — Maintains 25 V rating and identical capacitance with improved lifetime (7000 Hrs vs. 5000 Hrs). However, this part uses surface-mount technology, requiring PCB redesign and is not a direct through-hole replacement.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole PCB Replacement:

The Nichicon UPW1H330MED is the manufacturer-recommended substitute for the UTT1E330MDD. Both components share identical lead spacing (0.098" / 2.50mm), case diameter (0.248" / 6.30mm), and through-hole mounting configuration, enabling direct PCB footprint compatibility. The UPW1H330MED provides a higher voltage rating (50 V vs. 25 V), which is acceptable for applications designed for 25 V operation. The increased ripple current capability (90 mA @ 120 Hz vs. 48 mA) and lower impedance (430 mOhms vs. 2.1 Ohms) offer improved performance characteristics. However, the increased height (0.433" / 11.00mm vs. 0.276" / 7.00mm) requires verification of available board clearance.

For Active Product Status Requirement:

The Nichicon UCW1E330MCL1GS is an active product (not obsolete) with identical electrical specifications (33 µF, ±20%, 25 V) and improved lifetime rating (7000 Hrs @ 105°C vs. 5000 Hrs). This component is surface-mount technology, requiring PCB redesign and is not suitable for through-hole applications. Selection of this part is appropriate only when PCB redesign is feasible and active product status is a procurement requirement.

Compliance Verification:

All three components are ROHS3 Compliant and suitable for applications with regulatory compliance requirements. The UPW1H330MED and UCW1E330MCL1GS maintain full compliance status.

Frequently Asked Questions (FAQ)

Q: Can the UPW1H330MED be used as a direct replacement for the UTT1E330MDD?

A: Yes, for through-hole PCB applications. Both components have identical lead spacing (2.50mm) and case diameter (6.30mm). The primary consideration is the increased height of the UPW1H330MED (11.00mm vs. 7.00mm), which must be verified against available board clearance in your application.

Q: What is the advantage of the higher 50 V rating in the UPW1H330MED?

A: The 50 V rating provides derating margin for 25 V applications, improving reliability and extending component lifetime under stress conditions. The higher voltage rating does not affect electrical performance in 25 V circuits.

Q: Why is the UCW1E330MCL1GS not a direct replacement?

A: The UCW1E330MCL1GS uses surface-mount technology (SMD) rather than through-hole mounting. Direct PCB replacement is not possible without redesigning the footprint and assembly process. This part is suitable only when PCB redesign is planned.

Q: Are all three components RoHS compliant?

A: Yes. The UTT1E330MDD, UPW1H330MED, and UCW1E330MCL1GS are all ROHS3 Compliant, meeting regulatory requirements for restricted substance use.

Q: What is the impact of the lower lifetime rating in the UPW1H330MED?

A: The UPW1H330MED has a 2000 Hrs lifetime at 105°C compared to 5000 Hrs for the UTT1E330MDD. This specification applies only to continuous operation at maximum rated temperature. For applications operating below 105°C, the practical lifetime difference is minimal. Verify application temperature profile to assess impact.

Q: Can I use the UCW1E330MCL1GS in a through-hole design?

A: No. The UCW1E330MCL1GS is designed for surface-mount assembly and does not have through-hole leads. PCB redesign is required for this component.
