Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8QT93HPL2QLS03F is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain cool white 5700K specification with 5-Step MacAdam Ellipse tolerance to ensure consistent color output in lighting applications.

CRI (Color Rendering Index): A minimum CRI of 80 is required to preserve color fidelity in the application environment.

RoHS Compliance and Regulatory Status: All substitute parts must maintain RoHS compliance and equivalent ECCN/HTSUS classifications to satisfy supply chain and regulatory requirements.

Mounting Type and Surface Mount Compatibility: The substitute must be surface mount capable to integrate with existing PCB assembly processes.

Thermal and Electrical Characteristics: Forward voltage, test current, maximum current, and thermal resistance must be compatible with the circuit design and thermal management strategy of the application.

The substitute part SCP8QTJ5HEL1QLPF6E shares the same color specification, CRI rating, RoHS compliance, and thermal resistance. However, it operates in a different package format (1111 / 2828 Metric) with significantly different electrical characteristics (2.9V forward voltage, 700 mA test current, 320 lm output). This part is classified as active product status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8QT93HPL2QLS03F is classified as obsolete. The substitute part SCP8QTJ5HEL1QLPF6E carries active product status, ensuring continued manufacturing support, availability, and supply chain stability for future production runs and field replacements.

Compliance and Certification: Both parts maintain RoHS compliance and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, satisfying regulatory and export control requirements without modification to supply chain documentation.

Thermal Management Equivalence: Both parts specify identical thermal resistance of package (2°C/W) and equivalent moisture sensitivity levels (2A, 4 Weeks), ensuring compatibility with existing thermal design and storage protocols.

Electrical and Optical Differences: The substitute part operates at lower forward voltage (2.9V vs. 5.9V) and higher test current (700 mA vs. 150 mA), delivering greater luminous flux (320 lm vs. 111 lm) at higher efficiency (158 lm/W vs. 125 lm/W). These differences require circuit redesign and thermal management reassessment. The substitute exhibits a narrower viewing angle (120° vs. 145°), which may impact light distribution in the application.

Package and Form Factor: The substitute uses a larger package format (1111 / 2828 Metric vs. 0505 / 1313 Metric), requiring PCB layout modification and potential mechanical redesign of the light engine assembly.

Frequently Asked Questions (FAQ)

Q: Can the SCP8QTJ5HEL1QLPF6E be used as a direct drop-in replacement for the SCS8QT93HPL2QLS03F?

A: No. While both parts share identical color specification (cool white 5700K), CRI (80), and thermal resistance (2°C/W), they differ significantly in package size, electrical characteristics, and optical performance. The substitute requires circuit redesign to accommodate different forward voltage and current requirements, and PCB layout modification due to the larger package footprint.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Color and CCT matching (5700K 5-Step MacAdam Ellipse), (2) CRI equivalence (minimum 80), (3) RoHS compliance status, (4) Surface mount mounting type, (5) Thermal resistance compatibility (2°C/W), and (6) Regulatory classification equivalence (ECCN/HTSUS). Electrical characteristics (forward voltage, current, luminous flux) and optical properties (viewing angle) must be evaluated against specific application requirements.

Q: Why is the substitute part classified as active while the main part is obsolete?

A: Product status reflects manufacturing lifecycle decisions by Samsung Semiconductor, Inc. The LM102A series (SCS8QT93HPL2QLS03F) has reached end-of-life, while the LH231B series (SCP8QTJ5HEL1QLPF6E) remains in active production. Active status ensures continued availability, manufacturing support, and supply chain reliability for new designs and field replacements.

Q: What packaging differences exist between these parts?

A: The main part uses 0505 (1313 Metric) package measuring 1.34 mm × 1.34 mm with 0.42 mm seated height. The substitute uses 1111 (2828 Metric) package measuring 2.80 mm × 2.80 mm with 0.48 mm seated height. These dimensional differences require PCB footprint redesign and may impact mechanical assembly and thermal management strategies.

Q: Are there electrical compatibility concerns when substituting these parts?

A: Yes. The main part operates at 5.9V forward voltage with 150 mA test current, while the substitute operates at 2.9V with 700 mA test current. This represents a fundamental difference in electrical behavior requiring complete circuit redesign, including power supply adjustment, current limiting resistor recalculation, and thermal management reassessment. Maximum current ratings also differ significantly (250 mA vs. 2000 mA).

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Both maintain MSL 2A (4 Weeks) moisture sensitivity levels. These equivalences ensure compatibility with supply chain documentation and regulatory requirements without modification.

Q: How do the optical characteristics compare?

A: The main part delivers 111 lm at 150 mA with a 145° viewing angle. The substitute delivers 320 lm at 700 mA with a 120° viewing angle. The substitute provides greater total luminous output but with a narrower light distribution pattern. Application-specific requirements for light distribution and intensity must be evaluated before substitution.
