Substitute Part Grouping Explanation

Substitution eligibility for the UUD1C150MCL1GS is determined by the following critical parameters:

Capacitance: 15 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Mounting Type: Surface Mount (exact match required)
Physical Dimensions: 0.157" Dia (4.00mm) and compatible height
RoHS Compliance: ROHS3 Compliant (required for regulatory compliance)

Three substitute parts meet these core electrical and mechanical criteria: UCD1C150MCL1GS (Nichicon), UWF1C150MCL1GB (Nichicon), and 865080340002 (Würth Elektronik). Each maintains the same capacitance, voltage rating, tolerance, and polarization. Physical footprints are compatible with the original design. Variations in lifetime rating, impedance, and ripple current specifications are secondary parameters that may influence selection based on application requirements.

Engineering Selection Recommendations

UCD1C150MCL1GS is the primary parametric equivalent. It maintains identical electrical specifications, physical dimensions, and AEC-Q200 automotive certification. The lower impedance (1.35 Ohms vs. 1.8 Ohms) provides improved performance characteristics. Both parts are active in production with adequate inventory levels.

865080340002 (Würth Elektronik) is a direct functional equivalent with identical lifetime rating and operating temperature range. Physical dimensions are compatible. This part is active in production. Selection is appropriate for applications without automotive certification requirements.

UWF1C150MCL1GB is not recommended for new designs. This part is obsolete and carries a reduced lifetime rating of 1000 hours at 105°C compared to the 2000-hour specification of the main part. Higher impedance (2.6 Ohms) and larger physical dimensions (0.197" Dia) may present compatibility constraints. Use only when existing inventory must be consumed or legacy design support is required.

Frequently Asked Questions (FAQ)

Q: Can UCD1C150MCL1GS replace UUD1C150MCL1GS in automotive applications?

A: Yes. Both parts meet AEC-Q200 specifications, maintain identical capacitance, voltage rating, tolerance, and polarization. Physical footprints are identical. The UCD1C150MCL1GS features lower impedance, which is advantageous for ripple current performance.

Q: Is UWF1C150MCL1GB suitable for new production designs?

A: No. This part is obsolete and carries a reduced lifetime rating of 1000 hours at 105°C. Use only for legacy design support or existing inventory management.

Q: Can the Würth Elektronik part 865080340002 be used in automotive applications?

A: This part does not carry AEC-Q200 certification. It is suitable for general purpose applications with identical electrical specifications and 2000-hour lifetime rating. Automotive applications requiring AEC-Q200 compliance must use UUD1C150MCL1GS or UCD1C150MCL1GS.

Q: Are there physical compatibility concerns with UWF1C150MCL1GB?

A: Yes. The UWF1C150MCL1GB has a larger diameter (0.197" vs. 0.157") and different height (0.217" vs. 0.240"). PCB land pattern modifications may be required. Verify footprint compatibility before implementation.

Q: What is the impedance difference between substitute parts?

A: UCD1C150MCL1GS has the lowest impedance at 1.35 Ohms, followed by 865080340002 at 2 Ohms, UUD1C150MCL1GS at 1.8 Ohms, and UWF1C150MCL1GB at 2.6 Ohms. Lower impedance generally provides better high-frequency performance and lower ripple current stress.

Q: Which substitute part has the best inventory availability?

A: UUD1C150MCL1GS has the highest inventory at 3023 units. UCD1C150MCL1GS has 1970 units, 865080340002 has 2629 units, and UWF1C150MCL1GB has 1019 units.
