SCS7TT93HPL2TLS03F LED Equivalent & Substitute Parts

Part Overview

The SCS7TT93HPL2TLS03F is a surface-mount LED from Samsung Semiconductor's LM102A series, emitting neutral white light at 4000K with a 5-step MacAdam Ellipse specification. This component is classified as obsolete, making substitute part identification essential for ongoing production and maintenance applications. The part delivers 119 lm at 85°C under 150mA test current with a forward voltage of 5.9V and a 145° viewing angle in a compact 0505 (1313 Metric) package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7TT93HPL2TLS03F is determined by the following critical parameters:

Color and CCT Specification: Both the main part and substitute must emit white light at 4000K with 5-step MacAdam Ellipse tolerance to maintain color consistency in lighting applications.

Mounting Type and Surface Mount Compatibility: The main part uses surface-mount technology (SMD). Substitute parts must also be surface-mount devices to ensure compatibility with existing PCB layouts and assembly processes.

RoHS Compliance and Regulatory Status: The main part is RoHS Compliant. Substitute parts must maintain equivalent compliance to meet regulatory and procurement requirements.

Electrical Operating Range: While the main part operates at 150mA test current with a 5.9V forward voltage, substitute parts may operate at different test currents and forward voltages. Substitution is valid when the substitute can function within the application's power supply and current-limiting circuit design.

Luminous Flux and Efficiency: The main part delivers 119 lm at 85°C. Substitute parts with higher luminous flux output (such as 320 lm) are functionally compatible when the application circuit can accommodate the increased light output.

Package Footprint Considerations: The main part uses a 0505 (1313 Metric) package. Substitute parts with larger packages (such as 1111 or 2828 Metric) require PCB layout modification and are not direct drop-in replacements without design changes.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Same Footprint): The SCS7TT93HPL2TLS03F is obsolete with active inventory of 12,231 pieces available. No direct footprint-compatible substitute from the provided data maintains the 0505 (1313 Metric) package while meeting the 4000K neutral white specification.

For Functional Substitution with Design Modification: The SCP8TTJ5HEL1TLPF6E (LH231B series) is an active product from Samsung Semiconductor with 1,084 pieces in stock. This substitute shares the following compatibility criteria:

• Identical color specification: White, Neutral at 4000K with 5-step MacAdam Ellipse tolerance
• Both are RoHS Compliant surface-mount devices
• Both have identical thermal resistance (2°C/W) and MSL rating (2A, 4 Weeks)
• Higher luminous efficiency (158 lm/W versus 134 lm/W)
• Improved color rendering (CRI 80 versus CRI 70)

Critical Design Considerations for SCP8TTJ5HEL1TLPF6E Substitution:

The substitute operates at 2.9V forward voltage (versus 5.9V) and 700mA test current (versus 150mA). This requires circuit redesign for current limiting and power supply compatibility. The package footprint increases from 1.34 mm × 1.34 mm to 2.80 mm × 2.80 mm, necessitating PCB layout modification. The viewing angle decreases from 145° to 120°, which may affect light distribution in the application.

Compliance Status: Both parts maintain RoHS Compliance and equivalent regulatory certifications (ECCN: EAR99; HTSUS: 8541.41.0000), supporting procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SCP8TTJ5HEL1TLPF6E be used as a direct drop-in replacement for the SCS7TT93HPL2TLS03F?

A: No. While both parts emit 4000K neutral white light and are RoHS Compliant, the SCP8TTJ5HEL1TLPF6E uses a larger 1111 (2828 Metric) package compared to the 0505 (1313 Metric) package of the main part. Direct PCB substitution without layout modification is not possible. Additionally, the forward voltage differs (2.9V versus 5.9V), requiring circuit redesign.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Color and CCT specification (both must be 4000K neutral white with 5-step MacAdam Ellipse); (2) Mounting type (both must be surface-mount); (3) RoHS Compliance status; (4) Regulatory certifications (ECCN and HTSUS codes); (5) Thermal resistance and MSL rating; (6) Compatibility with the application's power supply and current-limiting circuit design.

Q: Why does the SCP8TTJ5HEL1TLPF6E have higher luminous flux (320 lm) compared to the main part (119 lm)?

A: The substitute operates at a higher test current (700mA versus 150mA) and uses a larger die within the larger package. Higher current and die size result in increased light output. The substitute also demonstrates improved efficiency (158 lm/W versus 134 lm/W).

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

A: Yes. The main part (SCS7TT93HPL2TLS03F) has a 145° viewing angle, while the substitute (SCP8TTJ5HEL1TLPF6E) has a 120° viewing angle. This narrower beam angle affects light distribution and may require application-specific evaluation.

Q: What is the impact of the different forward voltages (5.9V versus 2.9V)?

A: The forward voltage difference requires modification to the current-limiting circuit and power supply design. The main part requires higher voltage supply or series resistor configuration, while the substitute operates at lower voltage. Circuit redesign is mandatory for safe operation.

Q: Can the substitute be used in high-volume production immediately?

A: The SCP8TTJ5HEL1TLPF6E is an active product with 1,084 pieces in stock, supporting production continuity. However, PCB layout modification and circuit redesign are required before production implementation. Engineering validation and qualification testing are necessary before full-scale deployment.

Q: What is the difference in packaging format between the two parts?

A: The main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly processes, offering cost and handling advantages.
