LED SCS7QT93HPL2QLS03F Equivalent & Substitute Parts

Part Overview

The SCS7QT93HPL2QLS03F is a surface-mount LED from Samsung Semiconductor, Inc., classified as an LM102A series cool white lighting component with a correlated color temperature of 5700K. This part operates at 5.9V forward voltage with a test current of 150mA and delivers 119 lumens at 85°C. The component is mounted in a 0505 (1313 Metric) package with a 145° viewing angle and achieves 134 lumens per watt efficiency.

The product status is listed as Obsolete, making identification of functionally equivalent substitute components necessary for ongoing design requirements and production continuity. Substitute parts must maintain compatibility across electrical performance, optical characteristics, and mechanical mounting specifications while accounting for differences in package form factor and current requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCS7QT93HPL2QLS03F requires evaluation based on the following critical parameters:

Color and Optical Characteristics: The main part operates at 5700K cool white with a 5-Step MacAdam Ellipse specification and 145° viewing angle. Substitute parts must maintain the same correlated color temperature range and MacAdam Ellipse classification to ensure color consistency in lighting applications.

Electrical Performance: Forward voltage (Vf), test current, and maximum current ratings define the electrical operating envelope. The main part operates at 5.9V typical with 150mA test current and 250mA maximum current. Substitute parts may operate at different voltage and current levels, provided they are compatible with the application's power supply and circuit design.

Luminous Flux and Efficiency: The main part delivers 119 lumens at 85°C with 134 lumens per watt efficiency. Substitute parts with higher flux output or efficiency may be acceptable depending on application requirements, provided they do not exceed thermal or electrical constraints.

Package and Mounting: The main part uses a 0505 (1313 Metric) surface-mount package with 0.42mm maximum seated height. Substitute parts may use different package sizes (such as 1111 or 2828 Metric) if the application PCB layout can accommodate the larger footprint and height.

Compliance and Certifications: Both the main part and substitutes must maintain RoHS compliance and equivalent moisture sensitivity levels to ensure manufacturing and storage compatibility.

The identified substitute part SCP8QTJ5HEL1QLPF6E is from the same manufacturer (Samsung Semiconductor, Inc.) and maintains the same color temperature, MacAdam Ellipse specification, and compliance certifications, but operates at different electrical parameters and uses a larger package form factor.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The main part SCS7QT93HPL2QLS03F is classified as Obsolete, while the substitute part SCP8QTJ5HEL1QLPF6E is Active. Selection of the active substitute part ensures long-term availability and manufacturing continuity.

Compliance and Certification: Both parts maintain RoHS compliance and identical moisture sensitivity levels (2A, 4 Weeks), ensuring equivalent handling, storage, and manufacturing process compatibility.

Optical Compatibility: Both parts operate at 5700K cool white with 5-Step MacAdam Ellipse specification, maintaining color consistency. The substitute part provides higher CRI (80 versus 70), indicating improved color rendering capability.

Electrical and Thermal Parameters: The substitute part operates at significantly different electrical parameters: lower forward voltage (2.9V versus 5.9V), higher test current (700mA versus 150mA), and higher maximum current (2A versus 250mA). Circuit design modifications are required to accommodate these differences. Both parts maintain identical thermal resistance (2°C/W).

Package and Mechanical Considerations: The substitute part uses a larger 1111 (2828 Metric) package compared to the main part's 0505 (1313 Metric) package. PCB layout modifications are necessary to accommodate the increased footprint (2.80mm × 2.80mm versus 1.34mm × 1.34mm). The seated height difference is minimal (0.48mm versus 0.42mm).

Luminous Output: The substitute part delivers significantly higher luminous flux (320 lumens versus 119 lumens) and superior efficiency (158 lm/W versus 134 lm/W), providing enhanced lighting performance.

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

Frequently Asked Questions (FAQ)

Q: Can the SCP8QTJ5HEL1QLPF6E directly replace the SCS7QT93HPL2QLS03F without circuit modifications?

A: No. The substitute part operates at different electrical parameters (2.9V forward voltage and 700mA test current versus 5.9V and 150mA). Circuit design changes are required to accommodate the lower voltage and higher current requirements. Power supply and current-limiting resistor values must be recalculated.

Q: Are the color characteristics identical between the main part and substitute?

A: Both parts operate at 5700K cool white with 5-Step MacAdam Ellipse specification, ensuring color temperature consistency. The substitute part has a higher CRI (80 versus 70), providing improved color rendering. The narrower viewing angle (120° versus 145°) may affect light distribution patterns.

Q: What are the package compatibility implications?

A: The substitute part uses a 1111 (2828 Metric) package, which is significantly larger than the main part's 0505 (1313 Metric) package. PCB layout redesign is necessary to accommodate the larger footprint. The seated height difference (0.48mm versus 0.42mm) is minimal and typically not a constraint.

Q: Are both parts suitable for the same manufacturing and storage conditions?

A: Yes. Both parts maintain RoHS compliance and identical moisture sensitivity levels (2A, 4 Weeks), ensuring equivalent handling, storage, and manufacturing process compatibility.

Q: What is the luminous output difference between the parts?

A: The substitute part delivers 320 lumens at 85°C compared to 119 lumens for the main part, representing a 2.7× increase in luminous flux. This higher output may require thermal management evaluation in the application circuit.

Q: Can the substitute part be used in space-constrained applications?

A: The larger package size (2.80mm × 2.80mm versus 1.34mm × 1.34mm) makes the substitute part unsuitable for applications with strict PCB space limitations. The main part's smaller 0505 package is required for compact designs.

Q: What is the efficiency comparison?

A: The substitute part achieves 158 lumens per watt compared to 134 lumens per watt for the main part, representing a 17.9% efficiency improvement. This higher efficiency reduces power consumption for equivalent luminous output.
