Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8TT93HPL2TLS03F is determined by the following critical parameters:

Color and CCT Match: Both the main part and substitute must emit neutral white light at 4000K with 5-step MacAdam Ellipse specification to maintain color consistency in end-use applications.

Mounting and Package Compatibility: The main part uses surface-mount technology. Substitute parts must also be surface-mount LEDs to ensure compatibility with existing PCB layouts and assembly processes.

Electrical Performance Range: Forward voltage, test current, and maximum current ratings must fall within acceptable operating ranges for the target circuit. The substitute part SCP8TTJ5HEL1TLPF6E operates at 2.9V with a 700mA test current, representing a different electrical class but maintaining the same color and mounting characteristics.

Compliance and Certification: Both parts must maintain RoHS compliance and equivalent moisture sensitivity levels (MSL 2A) to satisfy regulatory and environmental requirements.

Luminous Flux and Efficiency: While absolute flux values may differ due to package size differences, the lumens-per-watt efficiency and CRI rating of 80 establish the baseline for optical performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS8TT93HPL2TLS03F is classified as obsolete, while the substitute SCP8TTJ5HEL1TLPF6E is active. For new designs or ongoing production requiring long-term component availability, the active substitute part is the appropriate selection.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring equivalent environmental and regulatory standing for applications subject to these requirements.

Electrical Circuit Redesign Requirement: The substitute part operates at significantly different electrical parameters: 2.9V forward voltage versus 5.9V, and 700mA test current versus 150mA. Circuit redesign is necessary to accommodate these differences. The substitute part's higher efficiency (158 lm/W versus 125 lm/W) and greater luminous output (320 lm versus 111 lm) indicate suitability for higher-power applications.

Package Size Transition: The substitute part uses a larger 1111 (2828 Metric) package compared to the 0505 (1313 Metric) main part. PCB layout modifications are required to accommodate the increased footprint and component density changes.

Optical Performance: Both parts deliver neutral white light at 4000K with CRI 80 and 5-step MacAdam Ellipse specification, maintaining color consistency. The substitute part's narrower viewing angle (120° versus 145°) may affect light distribution in applications requiring wide-angle illumination.

Frequently Asked Questions (FAQ)

Q: Can the SCP8TTJ5HEL1TLPF6E be used as a direct drop-in replacement for the SCS8TT93HPL2TLS03F?

A: No. While both parts share identical color temperature (4000K), CRI (80), and RoHS compliance, they differ in package size (0505 versus 1111), forward voltage (5.9V versus 2.9V), and test current (150mA versus 700mA). PCB layout and circuit modifications are required.

Q: What are the key compatibility criteria for substituting the SCS8TT93HPL2TLS03F?

A: Substitute parts must maintain: (1) neutral white color at 4000K with 5-step MacAdam Ellipse specification, (2) surface-mount technology, (3) RoHS compliance, and (4) MSL 2A rating. Electrical parameters and package dimensions may differ based on application requirements.

Q: Why does the substitute part have a lower forward voltage (2.9V) compared to the main part (5.9V)?

A: The SCP8TTJ5HEL1TLPF6E belongs to the LH231B series, which uses a different LED die and package architecture optimized for higher current operation (700mA versus 150mA). This results in lower forward voltage but higher luminous output and efficiency.

Q: Is the substitute part suitable for applications requiring a 145° viewing angle?

A: The SCP8TTJ5HEL1TLPF6E provides a 120° viewing angle, which is narrower than the main part's 145°. Applications requiring wide-angle light distribution may experience reduced performance. Optical design review is necessary.

Q: What is the impact of the larger package size (1111 versus 0505) on PCB design?

A: The substitute part's 1111 (2828 Metric) package is approximately 2.1 times larger in footprint than the 0505 (1313 Metric) main part. This requires PCB layout redesign, potentially affecting component density, thermal management, and assembly processes.

Q: Are both parts available in equivalent packaging formats?

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 offers cost advantages for large-quantity orders.

Q: Can the substitute part's higher efficiency (158 lm/W versus 125 lm/W) reduce power consumption in my application?

A: The substitute part's higher efficiency indicates better light output per watt. However, substitution requires circuit redesign to accommodate different electrical parameters. Power consumption reduction depends on the specific circuit implementation and operating current selected.
