Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8PT93HPL2PLS03F is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain cool white 6500K specification with 5-Step MacAdam Ellipse tolerance to ensure color consistency in lighting applications.

Mounting Type and Surface Mount Compatibility: The component must be surface mount capable for direct PCB integration without modification to existing assembly processes.

Electrical Operating Parameters: Forward voltage (Vf), test current, and maximum current ratings must be evaluated for circuit compatibility. Variations in these parameters may require circuit redesign or current-limiting adjustments.

Luminous Flux and Efficiency: Lumens output and lumens-per-watt efficiency determine brightness performance. Substitutes with different flux ratings may alter system-level illumination characteristics.

Package Dimensions and Thermal Properties: Physical size, height, and thermal resistance affect PCB layout, thermal management, and mechanical fit within enclosures.

Compliance and Product Status: RoHS compliance and active product status ensure long-term supply availability and regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

The SCP7PTJ5HEL1PLPF6E substitute shares the same color specification (6500K cool white) and thermal resistance (2°C/W) as the SCS8PT93HPL2PLS03F. However, significant electrical and physical differences exist that require circuit evaluation:

The substitute operates at 2.9V forward voltage compared to 5.9V in the main part, representing a 51% reduction. This difference necessitates recalculation of series resistor values and power supply compatibility assessment. The test current increases from 150mA to 700mA, requiring verification of PCB trace current capacity and thermal dissipation in the circuit layout.

The substitute delivers 320lm at test current versus 111lm in the main part, providing approximately 2.88 times greater luminous output. This increased brightness may alter system-level illumination performance and should be evaluated against application requirements.

The package size increases from 0505 (1.34mm x 1.34mm) to 1111 (2.80mm x 2.80mm), requiring PCB layout modification and verification of mechanical fit within enclosures or fixtures.

The CRI decreases from 80 to 70, indicating reduced color rendering capability. Applications requiring high color accuracy should account for this 10-point reduction.

The viewing angle narrows from 145° to 120°, affecting light distribution characteristics in optical systems.

Product Status Consideration:

The main part SCS8PT93HPL2PLS03F is classified as obsolete. The substitute SCP7PTJ5HEL1PLPF6E is active, ensuring continued availability for future production runs and maintenance stock replenishment.

Compliance:

Both parts are manufactured by Samsung Semiconductor, Inc. The main part is confirmed RoHS compliant. RoHS status for the substitute is not specified in the provided data and should be verified with the manufacturer before final selection.

Frequently Asked Questions (FAQ)

Q: Can the SCP7PTJ5HEL1PLPF6E be used as a direct drop-in replacement for the SCS8PT93HPL2PLS03F?

A: No. While both are cool white 6500K LEDs from Samsung Semiconductor, the substitute differs significantly in forward voltage (2.9V vs. 5.9V), test current (700mA vs. 150mA), luminous flux (320lm vs. 111lm), package size (1111 vs. 0505), and viewing angle (120° vs. 145°). Circuit redesign is required for electrical compatibility, and PCB layout modification is necessary for physical fit.

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

A: The substitute operates at 2.9V forward voltage, requiring a different series resistor calculation than the 5.9V main part. The test current increases to 700mA, necessitating verification of PCB trace current capacity. Maximum current rating increases from 250mA to 2A, allowing higher operational headroom but requiring thermal management assessment.

Q: How does the luminous output differ?

A: The substitute delivers 320lm at its test current (700mA) compared to 111lm at 150mA for the main part. This represents approximately 2.88 times greater brightness. Applications must evaluate whether this increased output is compatible with system-level illumination design or if optical diffusion modifications are necessary.

Q: Are there package compatibility issues?

A: Yes. 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. PCB footprints are not compatible, requiring layout redesign. Verify that the larger package fits within mechanical constraints of the application enclosure.

Q: What is the impact of the CRI difference?

A: The main part has a CRI of 80, while the substitute has a CRI of 70. This 10-point reduction indicates the substitute has lower color rendering capability. Applications requiring accurate color representation (such as display backlighting or color-critical inspection) should account for this difference.

Q: How does the viewing angle affect application performance?

A: The main part has a 145° viewing angle, providing wider light distribution. The substitute has a 120° viewing angle, concentrating light in a narrower cone. Applications requiring wide-angle illumination may experience reduced coverage with the substitute.

Q: Why is the main part obsolete?

A: The SCS8PT93HPL2PLS03F is classified as obsolete by the manufacturer. The substitute SCP7PTJ5HEL1PLPF6E is active, ensuring continued supply availability. For new designs or long-term production, the active substitute is preferable for supply chain stability.

Q: What packaging format differences exist?

A: The main part is supplied in Cut Tape (CT) format. The substitute is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly compatibility. Verify that assembly equipment supports the TR format or arrange for tape-to-tube conversion if necessary.

Q: Should RoHS compliance be verified for the substitute?

A: Yes. The main part is confirmed RoHS compliant. RoHS status for the substitute is not specified in the provided technical data. Confirm RoHS compliance with Samsung Semiconductor, Inc. before final component selection, particularly for applications subject to RoHS regulatory requirements.

Q: What thermal considerations apply to substitution?

A: Both parts have identical thermal resistance (2°C/W). However, the substitute operates at higher current (700mA vs. 150mA), generating greater heat dissipation. Verify that PCB thermal design and heat sinking are adequate for the increased power dissipation of the substitute.
