UWD1C150MCL1GS Equivalent & Substitute Parts

Part Overview

The UWD1C150MCL1GS is a 15 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Nichicon. This component is classified as Active and designed for general purpose applications with a rated lifetime of 2000 hours at 105°C. Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward automotive-grade components, or when inventory constraints require alternative sourcing from the same manufacturer's product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the UWD1C150MCL1GS is determined by the following core electrical and mechanical parameters:

Electrical Match: Capacitance (15 µF), voltage rating (16 V), and tolerance (±20%) must be identical
Thermal Performance: Operating temperature range (-55°C ~ 105°C) and polarization (Polar) must match
Mechanical Compatibility: Surface mount mounting type and radial can SMD package type must be maintained
Regulatory Compliance: RoHS3 compliance required for all substitutes

The substitute parts listed below meet these core criteria. Variations in series designation (UWD, UUD, UCD, UWF), physical dimensions, impedance, ripple current ratings, and product status indicate different design generations or application-specific variants within Nichicon's product portfolio.

Engineering Selection Recommendations

UUD1C150MCL1GS is suitable as a direct substitute when automotive-grade qualification (AEC-Q200) is required or preferred. This part maintains identical electrical specifications and thermal performance as the UWD1C150MCL1GS while offering enhanced reliability certification for automotive applications. Physical height increases from 5.80mm to 6.10mm; verify PCB layout clearance before substitution.

UCD1C150MCL1GS provides the lowest impedance (1.35 Ohms) among available substitutes and includes AEC-Q200 automotive qualification. This part is suitable for applications requiring improved high-frequency ripple current performance (90 mA @ 100 kHz). Physical dimensions match UUD1C150MCL1GS (6.10mm height). Moisture sensitivity level is not applicable for this series.

UWF1C150MCL1GB is classified as Obsolete and carries a reduced lifetime rating of 1000 hours at 105°C compared to the 2000-hour specification of the primary part. This substitute is not recommended for new designs. Physical dimensions differ significantly (5.00mm diameter, 5.30mm land size). Use only when legacy design compatibility is mandatory and thermal stress is minimal.

Frequently Asked Questions (FAQ)

Q: Can UUD1C150MCL1GS replace UWD1C150MCL1GS in general purpose applications?

A: Yes. Both parts share identical electrical specifications (15 µF, 16 V, ±20% tolerance) and thermal ratings (2000 Hrs @ 105°C). The UUD series includes AEC-Q200 automotive qualification, which does not restrict use in general purpose circuits. Verify that the increased height (6.10mm vs 5.80mm) does not violate PCB layout constraints.

Q: What is the primary difference between UCD1C150MCL1GS and UWD1C150MCL1GS?

A: The UCD series offers lower impedance (1.35 Ohms vs 1.8 Ohms) and higher ripple current capability at high frequency (90 mA @ 100 kHz). Both maintain identical capacitance, voltage, and lifetime specifications. The UCD is suitable for applications with stringent ripple current or ESR requirements.

Q: Is UWF1C150MCL1GB a viable substitute?

A: UWF1C150MCL1GB is classified as Obsolete and provides only 1000 hours lifetime at 105°C versus 2000 hours for the primary part. This part is not recommended for new designs. Use only when legacy circuit compatibility is mandatory and thermal operating conditions remain well below maximum ratings.

Q: What packaging differences exist among these substitutes?

A: UWD1C150MCL1GS, UUD1C150MCL1GS, and UCD1C150MCL1GS use identical 4.00mm diameter cans with 4.30mm x 4.30mm land sizes. UWF1C150MCL1GB uses a larger 5.00mm diameter can with 5.30mm x 5.30mm land size. UWF1C150MCL1GB is also supplied in Cut Tape (CT) & Digi-Reel® packaging versus Tape & Reel (TR) for other parts.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts (UUD1C150MCL1GS, UCD1C150MCL1GS, UWF1C150MCL1GB) are ROHS3 compliant and suitable for applications requiring RoHS compliance.
