Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8RT93HPL2RLS03F is determined by the following criteria based on provided electrical and mechanical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute maintain cool white 5000K specification with 5-Step MacAdam Ellipse tolerance, ensuring color consistency in lighting applications.

CRI (Color Rendering Index): Both parts specify CRI of 80, maintaining color rendering performance.

Mounting Type and Surface Mount Compatibility: Both components are surface mount devices suitable for automated assembly processes.

RoHS Compliance: Both parts meet RoHS compliance requirements, satisfying environmental and regulatory standards.

Thermal Resistance: Both parts specify 2°C/W thermal resistance, indicating equivalent thermal management characteristics.

Moisture Sensitivity Level (MSL): Both parts are rated 2A (4 Weeks), requiring identical moisture control during storage and handling.

The substitute part SCP8RTJ5HEL1RLPF6E differs in forward voltage (2.9V vs. 5.9V), test current (700mA vs. 150mA), package size (1111/2828 Metric vs. 0505/1313 Metric), and viewing angle (120° vs. 145°). These differences require circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8RT93HPL2RLS03F is classified as obsolete, while the substitute SCP8RTJ5HEL1RLPF6E maintains active product status with Samsung Semiconductor, Inc. Active status ensures continued availability, technical support, and manufacturing consistency.

Compliance and Certification: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, satisfying regulatory requirements for equivalent substitution.

Electrical Parameter Differences: The substitute part operates at significantly lower forward voltage (2.9V vs. 5.9V) and higher test current (700mA vs. 150mA). These differences require circuit redesign, including modifications to current-limiting resistors and power supply specifications. The substitute delivers higher luminous flux (320lm vs. 119lm) at its rated test current, indicating greater light output capability.

Mechanical and Optical Differences: The substitute employs a larger package footprint (1111/2828 Metric vs. 0505/1313 Metric) and narrower viewing angle (120° vs. 145°). PCB layout modifications and optical design adjustments are necessary to accommodate these dimensional and angular differences.

Thermal Management: Both parts specify identical thermal resistance (2°C/W), indicating equivalent thermal performance characteristics.

Selection of the SCP8RTJ5HEL1RLPF6E as a substitute requires comprehensive circuit and mechanical redesign validation to accommodate the electrical and dimensional parameter differences.

Frequently Asked Questions (FAQ)

Q: Can the SCP8RTJ5HEL1RLPF6E be used as a direct drop-in replacement for the SCS8RT93HPL2RLS03F?

A: No. While both parts share cool white 5000K color specification and CRI of 80, the substitute differs significantly in forward voltage (2.9V vs. 5.9V), test current (700mA vs. 150mA), package size (1111/2828 Metric vs. 0505/1313 Metric), and viewing angle (120° vs. 145°). Circuit redesign and PCB layout modifications are required.

Q: What are the key electrical differences between these parts?

A: The main part operates at 5.9V forward voltage with 150mA test current. The substitute operates at 2.9V forward voltage with 700mA test current. These differences necessitate modifications to current-limiting resistor values and power supply specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SCS8RT93HPL2RLS03F and SCP8RTJ5HEL1RLPF6E are RoHS compliant and carry identical ECCN and HTSUS classifications.

Q: What is the significance of the package size difference?

A: The main part uses a 0505 (1313 Metric) package measuring 1.34mm x 1.34mm. The substitute uses a 1111 (2828 Metric) package measuring 2.80mm x 2.80mm. This approximately 2x increase in footprint requires PCB layout redesign and may affect space-constrained applications.

Q: How do the viewing angles differ?

A: The main part specifies a 145° viewing angle, while the substitute specifies 120°. This 25° difference affects light distribution patterns and may require optical design adjustments in the end application.

Q: What is the luminous flux difference at rated test current?

A: At their respective test currents, the main part delivers 119 lumens while the substitute delivers 320 lumens. This difference reflects the higher test current (700mA vs. 150mA) of the substitute and indicates greater absolute light output capability.

Q: Are the moisture sensitivity requirements identical?

A: Yes. Both parts are rated MSL 2A (4 Weeks), requiring identical moisture control procedures during storage, handling, and assembly.

Q: What is the product status of each part?

A: The SCS8RT93HPL2RLS03F is classified as obsolete. The SCP8RTJ5HEL1RLPF6E is classified as active, ensuring continued availability and manufacturing support from Samsung Semiconductor, Inc.
