Engineering Selection Recommendations

Primary Substitute: SI-B8T463B20WW

The SI-B8T463B20WW is the recommended active substitute for the obsolete SI-B8T26256CUS. Both components are manufactured by Samsung Semiconductor, Inc., share the same base product platform (SI-B8), and maintain identical color temperature (4000K) and color rendering index (80) specifications. The substitute operates at active product status, ensuring ongoing supply chain availability and manufacturer support.

The SI-B8T463B20WW represents a generational advancement from V-Series Gen2 to V Gen3 architecture. Key differences include increased luminous flux output (8000 lm versus 4345 lm), higher maximum current rating (2.02A versus 1.35A), and increased forward voltage (45V versus 23.3V). The substitute features a longer physical length (1120 mm versus 560 mm) and reduced height profile (3.70 mm versus 5.50 mm).

Both components comply with identical export control classifications (ECCN: EAR99) and harmonized tariff codes (HTSUS: 8541.41.0000), confirming regulatory equivalence.

Secondary Substitute: SI-B8R463B20WW

The SI-B8R463B20WW is an alternative active substitute sharing the same V Gen3 platform and base product number (SI-B8). This component differs in color temperature specification, operating at 5000K (cool white) rather than 4000K (neutral white). Selection of this alternative requires confirmation that the application design accommodates the cooler color temperature. The SI-B8R463B20WW maintains identical electrical performance characteristics, physical dimensions, and compliance certifications as the SI-B8T463B20WW.

Frequently Asked Questions (FAQ)

Q: Why is the SI-B8T26256CUS classified as obsolete?

A: The SI-B8T26256CUS is an obsolete product, indicating Samsung Semiconductor has discontinued manufacturing and support. Active substitutes from the V Gen3 series are available to replace this component in new designs and production runs.

Q: What are the key compatibility criteria for substituting the SI-B8T26256CUS?

A: Substitutes must maintain the following specifications: Samsung Semiconductor manufacturer origin, SI-B8 base product platform, linear light strip configuration, flat lens type, white neutral color, 4000K color temperature, and 80 CRI rating. These parameters ensure functional and optical equivalence within the LED module category.

Q: How does the SI-B8T463B20WW differ electrically from the SI-B8T26256CUS?

A: The SI-B8T463B20WW operates at a higher forward voltage (45V versus 23.3V) and supports increased maximum current (2.02A versus 1.35A). Test current is slightly lower (1.01A versus 1.12A). These differences reflect generational improvements in the V Gen3 architecture. Circuit designs must accommodate the higher forward voltage requirement.

Q: What physical differences exist between these components?

A: The SI-B8T463B20WW is twice the length (1120 mm versus 560 mm) and features a reduced height profile (3.70 mm versus 5.50 mm). Both maintain 18 mm width and flat lens configuration. Mechanical integration must account for the longer length and lower profile dimensions.

Q: Can the SI-B8R463B20WW be used as a substitute?

A: The SI-B8R463B20WW is functionally compatible as an alternative substitute but operates at 5000K (cool white) instead of 4000K (neutral white). This color temperature difference affects the visual appearance of the light output. Selection requires confirmation that the application design accepts cool white color temperature.

Q: Are there packaging differences between the main part and substitutes?

A: The SI-B8T26256CUS packaging specification is not provided in the available data. The SI-B8T463B20WW and SI-B8R463B20WW are supplied in tray packaging. Confirm packaging requirements with procurement specifications.

Q: Do the substitutes maintain the same compliance certifications?

A: Yes. Both SI-B8T463B20WW and SI-B8R463B20WW share identical export control classification (ECCN: EAR99) and harmonized tariff code (HTSUS: 8541.41.0000) with the SI-B8T26256CUS, confirming regulatory equivalence.

Q: What is the inventory status of these components?

A: The SI-B8T26256CUS has 889 pieces in stock (obsolete status). The SI-B8T463B20WW has 992 pieces available (active status). The SI-B8R463B20WW has 877 pieces available (active status). Inventory levels are subject to change; confirm current availability with supplier.
