SCS7UT93HPL2ULS03F LED Equivalent & Substitute Parts

Part Overview

The SCS7UT93HPL2ULS03F is a warm white LED (3500K) manufactured by Samsung Semiconductor, Inc., designed for surface mount applications in the 0505 (1313 Metric) package format. This component operates at 5.9V forward voltage with a 150mA test current, delivering 111 lumens at 85°C and 125 lumens per watt efficiency. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain compatibility across electrical performance, color temperature, color rendering index, and mounting specifications while accommodating packaging and current delivery differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7UT93HPL2ULS03F is based on the following critical parameters that must align across equivalent components:

Color and Color Temperature Matching: Both the main part and substitute must deliver white light at 3500K with a 5-Step MacAdam Ellipse specification to ensure consistent color output in lighting applications.

Color Rendering Index (CRI): A CRI of 70 is maintained across all substitutes to preserve color fidelity in the intended application.

Mounting Technology: Surface mount technology is required for both components to ensure compatibility with automated assembly processes.

Electrical Characteristics: While forward voltage and test current may differ between the main part and substitutes, the substitute must operate within the constraints of the application circuit. The SCP7UTJ5HEL1ULPF6E operates at a lower forward voltage (2.9V) with higher test current (700mA), requiring circuit redesign considerations.

Thermal Performance: Thermal resistance of 2°C/W is consistent across both components, ensuring equivalent heat dissipation characteristics.

Compliance and Certification: RoHS compliance and ECCN/HTSUS classifications remain consistent, supporting regulatory requirements.

The SCP7UTJ5HEL1ULPF6E is identified as an active substitute, addressing the obsolete status of the main part while maintaining the specified color temperature and CRI parameters.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS7UT93HPL2ULS03F is classified as obsolete. The SCP7UTJ5HEL1ULPF6E is an active product from the same manufacturer, ensuring continued availability and supply chain stability for new designs and production continuity.

Compliance Alignment: Both components maintain RoHS compliance and identical ECCN/HTSUS classifications, supporting regulatory requirements across jurisdictions without modification to compliance documentation.

Electrical Performance Trade-offs: The substitute operates at significantly lower forward voltage (2.9V versus 5.9V) with proportionally higher test current (700mA versus 150mA). Circuit redesign is required to accommodate these electrical differences. The substitute delivers higher luminous flux (320lm versus 111lm) and improved efficiency (158 lm/W versus 125 lm/W), enabling potential power optimization in the application.

Photometric Consistency: Both components deliver identical color temperature (3500K) and color rendering index (70), ensuring consistent visual output in warm white lighting applications.

Thermal Characteristics: Equivalent thermal resistance (2°C/W) across both components ensures comparable heat dissipation performance in thermal management calculations.

Package and Form Factor Differences: The substitute uses a larger 1111 (2828 Metric) package compared to the main part's 0505 (1313 Metric) package. This requires PCB layout modification and may impact space-constrained applications. The substitute's larger footprint accommodates higher current delivery and improved thermal performance.

Viewing Angle Consideration: The substitute provides a narrower viewing angle (120° versus 145°), which may affect light distribution in applications requiring wide-angle illumination.

Frequently Asked Questions (FAQ)

Q: Can the SCP7UTJ5HEL1ULPF6E directly replace the SCS7UT93HPL2ULS03F without circuit modification?

A: No. The substitute operates at 2.9V forward voltage compared to the main part's 5.9V, requiring circuit redesign. Current-limiting resistor values and power supply specifications must be recalculated for the 700mA test current of the substitute.

Q: Are the color characteristics identical between these two parts?

A: Yes. Both components deliver white light at 3500K with a 5-Step MacAdam Ellipse specification and maintain a CRI of 70, ensuring consistent color output and color fidelity in lighting applications.

Q: What are the physical footprint implications of substitution?

A: The substitute uses a 1111 (2828 Metric) package measuring 2.80mm x 2.80mm, compared to the main part's 0505 (1313 Metric) package at 1.34mm x 1.34mm. PCB layout redesign is required to accommodate the larger footprint. Height difference is minimal (0.48mm versus 0.42mm).

Q: Does the substitute provide better performance?

A: The substitute delivers higher luminous flux (320lm versus 111lm) and improved efficiency (158 lm/W versus 125 lm/W). However, it operates at lower forward voltage and higher current, requiring circuit adaptation. The narrower viewing angle (120° versus 145°) may affect light distribution characteristics.

Q: Are both components RoHS compliant?

A: Yes. Both the SCS7UT93HPL2ULS03F and SCP7UTJ5HEL1ULPF6E are RoHS compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the primary reason for substitution?

A: The SCS7UT93HPL2ULS03F is classified as obsolete. The SCP7UTJ5HEL1ULPF6E is an active product from Samsung Semiconductor, Inc., ensuring supply availability and supporting long-term production requirements.

Q: How do the thermal characteristics compare?

A: Both components maintain identical thermal resistance of 2°C/W, providing equivalent heat dissipation performance in thermal management calculations and PCB thermal design.

Q: What packaging format differences exist?

A: The main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes.
