USV1E330MFD Equivalent & Substitute Parts

Part Overview

The USV1E330MFD is a 33 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution for the USV1E330MFD is determined by strict equivalence in the following parameters:

Capacitance: 33 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Substitutes are grouped into two categories based on mounting type and product status:

Category 1: Through-Hole Radial Can (Direct Form Factor)

UKL1E330MEDANA: Through-hole mounting, same lead spacing and footprint compatibility, but with reduced lifetime rating (1000 Hrs @ 105°C) and not recommended for new designs.

Category 2: Surface Mount Radial Can (Alternative Form Factor)

UUL1E330MCL1GS: Surface-mount variant with identical electrical specifications and matching 5000-hour lifetime rating. Active product status. Requires PCB redesign for mounting compatibility.

Engineering Selection Recommendations

For Direct Through-Hole Replacement (No PCB Redesign): UKL1E330MEDANA is mechanically and electrically compatible with identical lead spacing (0.098" / 2.50mm) and footprint dimensions. However, this part carries "Not For New Designs" status and has a reduced lifetime rating of 1000 hours at 105°C compared to the original 5000 hours. Use only for legacy system maintenance where the reduced lifetime is acceptable for the application duty cycle.

For New Designs or Long-Lifecycle Applications: UUL1E330MCL1GS is the recommended substitute. It maintains the full 5000-hour lifetime rating at 105°C, carries Active product status, and meets all electrical specifications. The surface-mount package requires PCB layout modification but ensures long-term supply availability and compliance with current manufacturing standards. This part is suitable for production designs requiring extended component lifecycle.

Compliance Considerations: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UKL1E330MEDANA be used as a direct drop-in replacement for USV1E330MFD? A: Yes, mechanically and electrically. Both are through-hole radial cans with identical lead spacing (2.50mm) and footprint dimensions (6.30mm diameter). However, UKL1E330MEDANA has a reduced lifetime rating (1000 Hrs @ 105°C vs. 5000 Hrs), making it suitable only for applications where this reduced rating is acceptable.

Q: What is the primary difference between UKL1E330MEDANA and UUL1E330MCL1GS? A: UKL1E330MEDANA is through-hole mounted with a taller profile (12.00mm height), while UUL1E330MCL1GS is surface-mount with a shorter profile (6.10mm height). UUL1E330MCL1GS maintains the original 5000-hour lifetime and has Active product status. UKL1E330MEDANA is marked "Not For New Designs."

Q: Does UUL1E330MCL1GS require PCB redesign? A: Yes. UUL1E330MCL1GS is a surface-mount component, whereas USV1E330MFD is through-hole. PCB layout and soldering process modifications are required. The component footprint is smaller (6.10mm height vs. 8.00mm), and mounting pads must be redesigned for SMD assembly.

Q: Are all three parts RoHS compliant? A: Yes. USV1E330MFD, UKL1E330MEDANA, and UUL1E330MCL1GS are all ROHS3 compliant and REACH unaffected.

Q: Which substitute should I choose for a legacy system repair? A: UKL1E330MEDANA is the appropriate choice for legacy through-hole systems requiring no PCB modification. Verify that the reduced 1000-hour lifetime at 105°C meets your application requirements.

Q: Which substitute is recommended for new product development? A: UUL1E330MCL1GS is recommended for new designs. It offers Active product status, full 5000-hour lifetime rating, and ensures long-term supply chain availability. Plan for surface-mount assembly capability.
