Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7PT93HPL2PUS03F is determined by alignment of the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must operate at cool white 6500K to maintain consistent color output in lighting applications.

CRI (Color Rendering Index): A CRI of 70 is maintained across both parts, ensuring equivalent color rendering performance.

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

RoHS Compliance: The substitute part must meet RoHS compliance requirements for regulatory and environmental standards.

Electrical Characteristics: While forward voltage, test current, and flux output may differ between the main part and substitute, these differences reflect technological advancement and package size variations rather than functional incompatibility. The substitute part SCP7PTJ5HEL1PUPF6E operates at different electrical parameters due to its larger package format (1111/2828 Metric versus 0505/1313 Metric), which accommodates higher current capacity and improved thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The SCP7PTJ5HEL1PUPF6E serves as a functional equivalent for the obsolete SCS7PT93HPL2PUS03F based on the following engineering criteria:

Product Status and Availability: The substitute part maintains active product status with Samsung Semiconductor, ensuring continued availability and supply chain reliability. The main part's obsolete classification necessitates transition to an alternative component.

Regulatory Compliance: Both parts maintain RoHS compliance and equivalent ECCN (EAR99) and HTSUS (8541.41.0000) classifications, satisfying regulatory requirements for international distribution and use.

Color and Rendering Consistency: Both components deliver cool white light at 6500K with CRI 70, maintaining consistent color output for lighting applications. The substitute incorporates 3-Step MacAdam Ellipse specification, providing enhanced color consistency control.

Thermal Performance: Both parts exhibit identical thermal resistance (2°C/W), ensuring equivalent thermal management characteristics in circuit design.

Surface Mount Compatibility: Both components are surface mount devices compatible with standard automated assembly processes, though the substitute's larger package (1111/2828 Metric) requires PCB layout adjustment from the original 0505 (1313 Metric) footprint.

Performance Enhancement: The substitute part delivers superior luminous efficiency (158 lm/W versus 134 lm/W) and higher absolute flux output (320lm versus 119lm), representing technological advancement within the Samsung LED product line.

Frequently Asked Questions (FAQ)

Q: Can the SCP7PTJ5HEL1PUPF6E directly replace the SCS7PT93HPL2PUS03F without circuit modification?

A: Direct pin-for-pin replacement is not possible due to different package formats (0505 versus 1111) and electrical characteristics (5.9V/150mA versus 2.9V/700mA). Circuit redesign is required, including PCB footprint modification and driver circuit adjustment to accommodate the substitute part's lower forward voltage and higher test current.

Q: What are the key compatibility criteria for LED substitution?

A: Primary compatibility criteria include color (White, Cool), correlated color temperature (6500K), color rendering index (CRI 70), mounting type (Surface Mount), and regulatory compliance (RoHS). Secondary considerations include package size, electrical parameters, and thermal characteristics based on specific application requirements.

Q: How does the package size difference affect substitution feasibility?

A: The substitute part's larger package (1111/2828 Metric, 2.80mm x 2.80mm) compared to the original (0505/1313 Metric, 1.34mm x 1.34mm) requires PCB layout redesign. The larger package accommodates higher current capacity and improved thermal dissipation, enabling the substitute's enhanced performance characteristics.

Q: Are there viewing angle differences between the main part and substitute?

A: Yes. The main part provides 145° viewing angle while the substitute provides 120° viewing angle. This difference reflects the larger package geometry and may impact light distribution in applications requiring wide-angle illumination.

Q: What electrical parameter adjustments are necessary for circuit implementation?

A: The substitute part operates at 2.9V forward voltage with 700mA test current, compared to the main part's 5.9V and 150mA. Driver circuits must be redesigned to accommodate the lower voltage and higher current requirements. Current-limiting resistor or active current regulation must be recalculated based on the substitute part's electrical specifications.

Q: Do both parts maintain equivalent thermal management?

A: Yes. Both parts exhibit 2°C/W thermal resistance, providing equivalent thermal performance. However, the substitute's larger package may offer improved heat dissipation characteristics in practical applications due to increased surface area.

Q: Is the substitute part's 3-Step MacAdam Ellipse specification significant for compatibility?

A: The 3-Step MacAdam Ellipse specification on the substitute part indicates enhanced color consistency control within a defined color space. This represents an improvement over the main part and does not create compatibility issues; it ensures tighter color tolerance for applications requiring consistent color output.
