Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SI-B8T26156CUS is determined by strict alignment of the following critical parameters:

Fixed Substitution Criteria:

• Manufacturer: Samsung Semiconductor, Inc.
• Base Product Number: SI-B8
• Type: LED Module
• Configuration: Linear Light Strip
• Color: White, Neutral
• CCT: 4000K
• CRI: 80
• Lens Type: Flat
• MSL: Not Applicable
• ECCN: EAR99
• HTSUS: 8541.41.0000

Flexible Parameters (within allowable ranges):

• Voltage - Forward (Vf): May vary based on module architecture
• Current - Test: May vary based on luminous flux output
• Luminous Flux: Must maintain neutral white output at 4000K
• Lumens/Watt: Efficacy improvements acceptable in active alternatives
• Physical dimensions: Length may increase; height and width must remain compatible with mounting constraints
• Viewing Angle: Additional optical performance acceptable

The substitute SI-B8T463B20WW meets all fixed criteria while offering enhanced performance characteristics suitable for direct replacement in applications requiring 4000K neutral white linear light strips.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SI-B8T463B20WW is a direct functional substitute for the obsolete SI-B8T26156CUS based on identical core specifications: manufacturer, base product family, module type, linear light strip configuration, neutral white color, 4000K color temperature, CRI 80, and flat lens type. Both modules carry identical export and tariff classifications (EAR99, 8541.41.0000).

Critical Design Considerations:

1. Voltage Compatibility: The substitute operates at 45V forward voltage compared to 24.4V in the original. Driver circuits and power supply specifications must be verified for compatibility with the higher voltage requirement.

2. Physical Integration: The substitute module is 1120 mm in length (double the original 560 mm) with a reduced height of 3.70 mm versus 5.50 mm. Mechanical mounting and thermal management designs must accommodate these dimensional changes.

3. Performance Enhancement: The substitute delivers 8000 lumens typical output with 176 lm/W efficacy, representing a significant performance increase over the original 3908 lumens at 143 lm/W. This enhanced output is compatible with applications requiring higher light levels at identical color temperature and rendering index.

4. Product Status: The substitute is in active production status, ensuring long-term supply chain availability and technical support, eliminating obsolescence risk associated with the original part.

Compliance Status:

Both modules maintain identical regulatory classifications and moisture sensitivity levels, confirming compliance equivalence for applications subject to export controls or tariff considerations.

Frequently Asked Questions (FAQ)

Q: Can SI-B8T463B20WW directly replace SI-B8T26156CUS in existing installations?

A: Direct physical replacement requires verification of driver voltage compatibility (45V vs. 24.4V) and mechanical mounting accommodation for the longer module length (1120 mm vs. 560 mm) and lower profile (3.70 mm vs. 5.50 mm). Electrical and mechanical integration must be confirmed before deployment.

Q: What is the primary reason for substitution?

A: The SI-B8T26156CUS is classified as obsolete. The SI-B8T463B20WW is an active production alternative from the same manufacturer and base product family, ensuring continued availability and supply chain continuity.

Q: Are the color temperature and color rendering index identical?

A: Yes. Both modules operate at 4000K color temperature with CRI 80, ensuring identical neutral white light quality and color accuracy for applications requiring these specifications.

Q: What are the key electrical differences?

A: The substitute operates at 45V forward voltage (vs. 24.4V), with test current of 1.01A (vs. 1.12A) and maximum current of 2.02A (vs. 1.62A). Power supply and driver circuits must be rated for the higher voltage and current specifications.

Q: Does the substitute provide better performance?

A: The substitute delivers 8000 lumens typical output with 176 lm/W efficacy, compared to 3908 lumens at 143 lm/W in the original. This represents enhanced light output and energy efficiency while maintaining identical color temperature and rendering characteristics.

Q: Are packaging and handling requirements the same?

A: Both modules have identical moisture sensitivity level (Not Applicable) and export classifications (EAR99). The substitute is supplied in Tray packaging. Standard handling procedures for LED modules apply to both parts.

Q: What is the viewing angle specification?

A: The original SI-B8T26156CUS does not specify viewing angle. The substitute SI-B8T463B20WW specifies 118° viewing angle, providing additional optical performance data for system design purposes.
