Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8UT93HPL2UUS03F is determined by the following critical parameters:

Color Temperature Match: Both the main part and substitute must operate at 3500K warm white specification to maintain consistent color output in lighting applications.

Color Rendering Index (CRI): The CRI value of 80 establishes the minimum acceptable color fidelity requirement for substitute selection.

Mounting Technology: Surface mount technology (SMD) is mandatory for compatibility with automated assembly processes.

Compliance Standards: RoHS compliance is required for regulatory adherence in target markets.

Thermal Characteristics: Thermal resistance of 2°C/W represents the thermal management capability threshold.

The substitute part SCP8UTJ5HEL1ULNF6E satisfies these core substitution criteria while operating under different electrical parameters (2.9V forward voltage, 700mA test current) and physical dimensions (1111/2828 Metric package). The substitute maintains identical color temperature, CRI rating, thermal resistance, and compliance status, enabling functional equivalence despite dimensional and electrical differences.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8UT93HPL2UUS03F is classified as obsolete, making the SCP8UTJ5HEL1ULNF6E an appropriate substitute due to its active product status. Active status ensures ongoing manufacturing availability and supply chain continuity.

Compliance Alignment: Both parts maintain RoHS compliance, satisfying regulatory requirements for electronics manufacturing and distribution in regulated markets.

Moisture Sensitivity Management: The substitute part carries MSL Level 2A (4 Weeks) compared to the main part's MSL Level 1 (Unlimited). This difference requires adherence to moisture control protocols during storage and handling, with a maximum floor life of 4 weeks after bag opening under specified humidity conditions.

Electrical Parameter Differences: The substitute operates at lower forward voltage (2.9V versus 5.9V) and higher test current (700mA versus 150mA). Circuit designs must accommodate these electrical characteristics through appropriate current-limiting and voltage regulation adjustments.

Photometric Performance: The substitute delivers higher luminous flux (300lm versus 111lm) and superior luminous efficacy (148 lm/W versus 125 lm/W), providing enhanced light output for equivalent power consumption.

Physical Footprint: The substitute occupies a larger PCB footprint (2.80mm × 2.80mm versus 1.34mm × 1.34mm). PCB layout modifications are necessary to accommodate the larger 1111 (2828 Metric) package.

Optical Characteristics: The substitute features a narrower viewing angle (120° versus 145°), affecting light distribution patterns in applications requiring wide-angle illumination.

Frequently Asked Questions (FAQ)

Q: Can the SCP8UTJ5HEL1ULNF6E directly replace the SCS8UT93HPL2UUS03F 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. Current-limiting resistors and voltage regulation must be recalculated for the substitute's electrical characteristics.

Q: Are both parts suitable for the same lighting applications?

A: Both parts share identical color temperature (3500K) and CRI (80), making them suitable for warm white lighting applications requiring equivalent color output. However, the substitute's higher luminous flux and narrower viewing angle may alter light distribution and intensity profiles.

Q: What is the impact of the MSL Level difference?

A: The substitute's MSL Level 2A (4 Weeks) requires stricter moisture control compared to the main part's MSL Level 1 (Unlimited). Storage must maintain specified humidity levels, and the component must be used within 4 weeks of bag opening. The main part has no such time restriction.

Q: Does the larger package size affect assembly compatibility?

A: Yes. The substitute's 1111 (2828 Metric) package is significantly larger than the main part's 0505 (1313 Metric) package. PCB layout, solder pad dimensions, and pick-and-place equipment settings require modification to accommodate the larger footprint.

Q: Are both parts from the same manufacturer?

A: Yes. Both parts are manufactured by Samsung Semiconductor, Inc., ensuring consistent quality standards and manufacturing processes.

Q: What is the significance of the 5-Step MacAdam Ellipse specification on the substitute?

A: The 5-Step MacAdam Ellipse indicates tighter color consistency tolerances for the substitute part, ensuring more uniform color output across production batches compared to standard color temperature specifications.

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

A: No. The substitute's larger physical dimensions (0.110" × 0.110" versus 0.053" × 0.053") make it unsuitable for applications with strict size limitations. The main part's smaller 0505 package is required for compact designs.

Q: How do the thermal characteristics compare?

A: Both parts maintain identical thermal resistance (2°C/W), providing equivalent thermal management performance. However, the substitute's higher current rating (2A maximum versus 250mA maximum) may generate greater heat dissipation in high-current applications.
