LED SCS7TT93HPL2TUS03F Equivalent & Substitute Parts

Part Overview

The SCS7TT93HPL2TUS03F is a surface-mount LED lighting component manufactured by Samsung Semiconductor, Inc., featuring neutral white 4000K color temperature. This part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity. The LM102A series delivers 119 lumens at 85°C under 150mA test current with a forward voltage of 5.9V and 145° viewing angle in a compact 0505 (1313 Metric) package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCS7TT93HPL2TUS03F requires evaluation against the following critical parameters:

Color and CCT Matching: Both the main part and substitute must deliver neutral white light at 4000K to maintain color consistency in lighting applications.

Luminous Flux Performance: The main part produces 119 lumens at 85°C under 150mA test conditions. Substitute parts must deliver comparable luminous output to satisfy application brightness requirements.

Electrical Characteristics: Forward voltage (Vf), test current, and maximum current ratings must be compatible with existing circuit designs and power supply specifications.

Package and Mounting: Surface-mount package type and physical dimensions determine PCB layout compatibility. The 0505 (1313 Metric) package footprint is a critical constraint for board-level integration.

Viewing Angle: The 145° viewing angle defines the light distribution pattern. Substitutes with significantly different viewing angles may alter system optical performance.

Compliance and Reliability: RoHS compliance status and moisture sensitivity level (MSL) ensure regulatory adherence and handling requirements during manufacturing and storage.

The identified substitute SCP7TTJ5HEL1TUQF6E shares the same color temperature (4000K), CRI (70), and manufacturer (Samsung Semiconductor, Inc.), but differs in series designation, package size, electrical ratings, and luminous flux output.

Parameter Comparison

Engineering Selection Recommendations

Direct Pin-for-Pin Substitution: The SCP7TTJ5HEL1TUQF6E is not a direct pin-for-pin replacement for the SCS7TT93HPL2TUS03F. Critical differences in package size (0505 vs. 1111), forward voltage (5.9V vs. 2.9V), and test current (150mA vs. 700mA) necessitate circuit and PCB layout modifications.

Color Temperature Compatibility: Both components deliver neutral white light at 4000K with CRI 70, satisfying color consistency requirements for applications where the original part was specified.

Electrical Circuit Redesign: The substitute operates at significantly lower forward voltage (2.9V vs. 5.9V) and requires higher current (700mA vs. 150mA). Existing power supply and current-limiting circuits must be redesigned to accommodate these electrical characteristics.

Optical Performance Consideration: The substitute exhibits a narrower viewing angle (120° vs. 145°), which alters light distribution. Applications requiring the original 145° beam pattern may experience performance degradation.

Package and Layout Modification: The substitute's larger package footprint (2.80mm × 2.80mm vs. 1.34mm × 1.34mm) requires PCB redesign and cannot be accommodated in existing board layouts designed for the 0505 package.

Product Status and Availability: The substitute is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Moisture Handling: The substitute carries MSL 2A (4 Weeks) versus MSL 1 (Unlimited) for the main part, requiring more stringent moisture control during storage and handling to prevent component degradation.

Frequently Asked Questions (FAQ)

Q: Can the SCP7TTJ5HEL1TUQF6E be used as a direct replacement without circuit modifications?

A: No. The substitute differs in forward voltage (2.9V vs. 5.9V), test current (700mA vs. 150mA), and package size (1111 vs. 0505). Circuit redesign and PCB layout modification are required.

Q: Are the color characteristics identical between the main part and substitute?

A: Both components deliver neutral white light at 4000K with CRI 70. The substitute includes 3-Step MacAdam Ellipse specification for enhanced color consistency, making it suitable for color-critical applications.

Q: What is the impact of the different viewing angles?

A: The main part provides 145° viewing angle while the substitute offers 120°. This narrower beam in the substitute concentrates light output over a smaller area, altering the optical distribution pattern in the application.

Q: Does the substitute offer higher luminous output?

A: Yes. The substitute produces 340 lumens at 85°C (test current 700mA) compared to 119 lumens for the main part (test current 150mA). However, this higher output is achieved at significantly higher current consumption.

Q: What are the moisture sensitivity implications?

A: The main part carries MSL 1 (Unlimited), allowing indefinite storage without moisture control. The substitute carries MSL 2A (4 Weeks), requiring storage in controlled humidity environments and limiting shelf life to 4 weeks after moisture barrier bag opening.

Q: Is the substitute RoHS compliant?

A: RoHS compliance status is not specified in the provided data for the substitute. Verification with the manufacturer is recommended for regulatory compliance documentation.

Q: Can the substitute be used in space-constrained PCB designs?

A: No. The substitute's larger package (2.80mm × 2.80mm) compared to the main part (1.34mm × 1.34mm) makes it unsuitable for designs with tight component spacing or miniaturized layouts.

Q: What is the efficiency difference between the two parts?

A: The main part delivers 134 lm/W at test current, while the substitute achieves 167 lm/W. The substitute exhibits higher luminous efficiency, though this advantage is offset by higher absolute current requirements.

Q: Are both parts suitable for 4000K neutral white lighting applications?

A: Yes. Both components are specified for 4000K neutral white color temperature and are suitable for general lighting, display backlighting, and architectural lighting applications requiring this color temperature.
