Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8WT93HPL2WLS03F is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute maintain warm white 2700K specification with 5-Step MacAdam Ellipse tolerance, ensuring color consistency in lighting applications.

Color Rendering Index (CRI): Both parts specify CRI 80, maintaining color fidelity requirements.

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

RoHS Compliance and Environmental Standards: Both parts meet RoHS compliance and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Moisture Sensitivity Level: Both parts specify MSL 2A (4 Weeks), requiring identical handling and storage protocols.

The substitute part SCP8WTJ5HEL1WLMF6E differs in package size (1111/2828 Metric versus 0505/1313 Metric), electrical characteristics (2.9V forward voltage, 700mA test current), and optical properties (120° viewing angle versus 145°), reflecting a different LED die and package architecture while maintaining the same color specification and compliance profile.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8WT93HPL2WLS03F is classified as obsolete. The substitute part SCP8WTJ5HEL1WLMF6E carries active product status, ensuring continued availability and manufacturing support from Samsung Semiconductor, Inc.

Compliance and Certification: Both parts maintain identical RoHS compliance status and share the same ECCN and HTSUS classifications, confirming regulatory equivalence for export and supply chain purposes.

Packaging Format: The main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly integration but does not alter functional compatibility.

Electrical and Optical Differences: The substitute part operates at lower forward voltage (2.9V versus 5.9V) and higher test current (700mA versus 150mA), producing higher luminous flux (280lm versus 103lm) at the specified test condition. The substitute exhibits a narrower viewing angle (120° versus 145°). These differences require circuit redesign and optical layout evaluation for applications where the original part's specific electrical or optical characteristics are critical.

Moisture Sensitivity: Both parts specify identical MSL 2A (4 Weeks) classification, requiring equivalent handling protocols during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the SCP8WTJ5HEL1WLMF6E directly replace the SCS8WT93HPL2WLS03F in existing designs?

A: Direct replacement requires circuit redesign. The substitute operates at 2.9V forward voltage compared to 5.9V in the original part, necessitating modification of current-limiting resistor values and power supply specifications. The package size difference (1111 versus 0505) requires PCB layout revision.

Q: What are the key compatibility factors between these two parts?

A: Both parts share identical color specification (warm white 2700K with 5-Step MacAdam Ellipse tolerance), CRI rating (80), mounting type (surface mount), RoHS compliance status, and moisture sensitivity level (MSL 2A). These parameters ensure functional equivalence in color-critical lighting applications.

Q: How do the package size differences affect assembly?

A: The SCS8WT93HPL2WLS03F uses a 0505 (1313 Metric) package measuring 1.34mm x 1.34mm, while the SCP8WTJ5HEL1WLMF6E uses a 1111 (2828 Metric) package measuring 2.80mm x 2.80mm. This 2.1x increase in footprint area requires PCB redesign and may affect thermal management and optical spacing in compact applications.

Q: What is the significance of the viewing angle difference?

A: The main part specifies 145° viewing angle, providing wider light distribution, while the substitute specifies 120° viewing angle. Applications requiring wide-angle illumination may experience reduced light spread with the substitute part.

Q: Are there differences in thermal management between these parts?

A: Both parts specify identical thermal resistance of 2°C/W. However, the larger package size of the substitute may provide improved thermal coupling to the PCB, potentially offering better heat dissipation in high-current applications.

Q: What packaging format differences exist, and how do they affect procurement?

A: The main part is supplied in Cut Tape (CT) format, suitable for manual or semi-automated assembly. The substitute is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly lines. TR format typically offers cost advantages in production quantities.

Q: Are both parts suitable for the same environmental and regulatory applications?

A: Both parts maintain RoHS compliance and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence for environmental and export compliance purposes.
