Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8RT93HPL2RUS03F requires evaluation of the following critical parameters:

Color Temperature Matching: Both the main part and substitute must operate at 5000K cool white specification to maintain consistent lighting output in the application.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings must be evaluated against circuit design requirements. The main part operates at 5.9V with 150mA test current and 250mA maximum current.

Luminous Output: Flux output at specified test conditions determines brightness performance. The main part delivers 119 lumens at 85°C under 150mA test current.

Color Rendering Index (CRI): Both parts maintain CRI of 80, ensuring consistent color reproduction characteristics.

Package Geometry: Surface mount package type, physical dimensions, and height specifications must accommodate existing PCB layouts and assembly processes.

Compliance and Certification: RoHS compliance and MSL ratings must be maintained for manufacturing and storage requirements.

The identified substitute part SCP8RTJ5HEL1RLPF6E shares the 5000K color temperature specification and RoHS compliance status, enabling functional substitution with documented parameter differences.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8RT93HPL2RUS03F is classified as obsolete, while the substitute part SCP8RTJ5HEL1RLPF6E maintains active product status with current manufacturing availability. This status difference supports transition to the substitute component for new designs and ongoing production requirements.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL 2A (4 Weeks) ratings, ensuring equivalent handling, storage, and manufacturing process compatibility.

Electrical Parameter Differences: The substitute part operates at significantly lower forward voltage (2.9V versus 5.9V) and higher test current (700mA versus 150mA). Circuit design modifications are required to accommodate these electrical characteristic differences. The substitute part delivers higher luminous output (320lm versus 119lm) at its specified test current.

Package Geometry Differences: 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 dimensions (2.80mm x 2.80mm versus 1.34mm x 1.34mm).

Viewing Angle Variation: The substitute part provides a narrower viewing angle (120° versus 145°), which may affect light distribution characteristics in the application.

Efficiency Consideration: The substitute part demonstrates higher luminous efficacy (158 lm/W versus 134 lm/W), indicating improved energy efficiency at its specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the SCP8RTJ5HEL1RLPF6E directly replace the SCS8RT93HPL2RUS03F without circuit modifications?

A: No. The substitute part requires circuit design changes due to different forward voltage (2.9V versus 5.9V) and test current (700mA versus 150mA) specifications. Current-limiting resistor values and power supply voltage must be recalculated for the substitute component.

Q: What are the primary differences between these two parts?

A: The main differences are: forward voltage (5.9V main versus 2.9V substitute), test current (150mA main versus 700mA substitute), luminous output (119lm main versus 320lm substitute), package size (0505 main versus 1111 substitute), and viewing angle (145° main versus 120° substitute). Both maintain 5000K color temperature and 80 CRI specifications.

Q: Is the substitute part suitable for space-constrained PCB layouts?

A: No. The substitute part's larger package footprint (2.80mm x 2.80mm versus 1.34mm x 1.34mm) requires additional PCB area. Applications with strict space limitations may not accommodate this component without layout redesign.

Q: Do both parts have equivalent moisture sensitivity requirements?

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

Q: What is the significance of the 5-Step MacAdam Ellipse specification on the substitute part?

A: The 5-Step MacAdam Ellipse specification on the substitute part indicates tighter color temperature tolerance control compared to the main part, ensuring more consistent color output across production batches.

Q: Are there inventory availability differences between these parts?

A: Yes. The main part (SCS8RT93HPL2RUS03F) has 878 pieces in stock with obsolete status. The substitute part (SCP8RTJ5HEL1RLPF6E) has 751 pieces in stock with active product status, indicating ongoing manufacturing support.

Q: Can the substitute part be used in applications requiring the exact 145° viewing angle of the main part?

A: No. The substitute part's 120° viewing angle differs from the main part's 145° specification. Applications dependent on the wider viewing angle require evaluation of light distribution impact before substitution.
