Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7RT93HPL2RUS03F is evaluated based on the following critical parameters:

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

Luminous Flux Performance: The substitute must deliver comparable light output at its specified test current and temperature conditions to ensure adequate illumination levels.

Color Rendering Index (CRI): A CRI value of 70 is maintained across substitute parts to preserve color accuracy requirements.

Electrical Characteristics: Forward voltage and test current specifications determine circuit compatibility and power supply requirements.

Package and Mounting: Surface mount technology and package dimensions define physical compatibility with printed circuit board layouts.

Compliance and Environmental Standards: RoHS compliance and moisture sensitivity ratings ensure regulatory conformance and handling requirements remain consistent.

The substitute part SCP7RTJ5HEL1RLQF6E shares the same color temperature, CRI rating, and surface mount technology, making it a valid alternative despite differences in package size, electrical ratings, and luminous flux specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS7RT93HPL2RUS03F is classified as Obsolete, while the substitute SCP7RTJ5HEL1RLQF6E maintains Active product status. Selection of the active substitute ensures ongoing manufacturer support, availability, and compliance with current production standards.

Regulatory Compliance: Both parts maintain RoHS compliance and share identical ECCN and HTSUS classifications, confirming equivalent regulatory standing for procurement and export purposes.

Electrical Compatibility: The substitute operates at a 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 differences. Power supply and current-limiting resistor values must be recalculated based on the substitute's specifications.

Luminous Output: The substitute delivers approximately 2.85 times greater luminous flux (340 lm versus 119 lm) at its test conditions. Applications requiring the original light output level must account for this increased brightness through optical design adjustments or current derating.

Package Dimensions: The substitute uses a larger 1111 (2828 Metric) package compared to the original 0505 (1313 Metric) package. Printed circuit board layout modifications are necessary to accommodate the increased footprint.

Viewing Angle: The substitute provides a narrower viewing angle (120° versus 145°). Applications requiring wide-angle light distribution must evaluate whether this reduction affects performance.

Moisture Sensitivity: The substitute carries MSL 2A (4 Weeks) versus MSL 1 (Unlimited) for the original part. Enhanced moisture control during storage and handling is required.

Frequently Asked Questions (FAQ)

Q: Can the SCP7RTJ5HEL1RLQF6E directly replace the SCS7RT93HPL2RUS03F without circuit modifications?

A: No. The substitute requires circuit design changes due to different forward voltage (2.9V versus 5.9V) and test current (700mA versus 150mA) specifications. Power supply voltage, current-limiting resistor values, and potentially thermal management must be recalculated.

Q: What is the primary reason for substitution?

A: The SCS7RT93HPL2RUS03F is classified as Obsolete. The SCP7RTJ5HEL1RLQF6E is an Active product from the same manufacturer, ensuring continued availability and support.

Q: Are both parts RoHS compliant?

A: Yes. Both the SCS7RT93HPL2RUS03F and SCP7RTJ5HEL1RLQF6E are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: How does the luminous output differ between these parts?

A: The substitute delivers 340 lumens at 85°C compared to 119 lumens for the original part at the same temperature. This represents a significant increase in light output. Applications must account for this difference through optical design or current derating strategies.

Q: What are the package dimension differences?

A: The original 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. Printed circuit board layout modifications are required.

Q: Do both parts have the same color temperature?

A: Yes. Both parts operate at 5000K cool white. The substitute specifies 5-Step MacAdam Ellipse color binning, which provides tighter color consistency.

Q: What is the difference in viewing angle?

A: The original part provides a 145° viewing angle, while the substitute provides a 120° viewing angle. Applications requiring wide-angle light distribution must evaluate this reduction.

Q: Are there moisture sensitivity differences?

A: Yes. The original part carries MSL 1 (Unlimited), while the substitute carries MSL 2A (4 Weeks). The substitute requires enhanced moisture control during storage and handling.

Q: What is the efficiency difference between these parts?

A: The original part delivers 134 lumens per watt, while the substitute delivers 167 lumens per watt at their respective test conditions. The substitute demonstrates higher luminous efficiency.

Q: Can I use the same circuit board design for both parts?

A: No. The different package sizes (0505 versus 1111), electrical specifications (5.9V/150mA versus 2.9V/700mA), and luminous output require circuit board redesign and electrical circuit modifications.
