Substitute Part Grouping Explanation

Substitution of the obsolete SI-B8V26156CUS is determined by the following critical parameters:

Primary Substitution Criteria:

• Color Temperature (CCT): 3000K warm white specification
• Color Rendering Index (CRI): Minimum 80
• Configuration: Linear light strip format
• Lens Type: Flat optical surface
• Packaging: Tray format
• Base Product Number: SI-B8 family designation
• Compliance: ECCN EAR99 and HTSUS 8541.41.0000 classification

The substitute part SI-B8V463B20WW meets all primary substitution criteria. Both modules share identical color temperature (3000K), CRI (80), configuration (linear light strip), lens type (flat), packaging (tray), and regulatory classifications. The substitute belongs to the same SI-B8 base product family and is classified as Active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SI-B8V463B20WW is a direct substitute for the obsolete SI-B8V26156CUS based on matching functional and regulatory parameters. Both modules are manufactured by Samsung Semiconductor, Inc., share identical color temperature (3000K), CRI (80), configuration (linear light strip), lens type (flat), and regulatory classifications (ECCN EAR99, HTSUS 8541.41.0000).

Key Differences Requiring System Evaluation:

1. Forward Voltage (Vf): The substitute operates at 45V compared to 24.4V for the main part. Power supply circuits must accommodate this higher voltage requirement.

2. Luminous Flux Output: The substitute delivers 7570 lm versus 3607 lm for the main part, representing approximately 110% higher light output. System thermal management and optical design may require adjustment.

3. Physical Dimensions: The substitute measures 1120 mm in length versus 560 mm for the main part. Mechanical mounting and form factor compatibility must be verified for the target application.

4. Height Profile: The substitute is 3.70 mm tall compared to 5.50 mm for the main part, providing a lower profile design.

5. Product Status: The substitute is classified as Active, ensuring continued manufacturing support, availability, and technical documentation access.

Regulatory Compliance:

Both parts carry identical export control (ECCN EAR99) and tariff classifications (HTSUS 8541.41.0000), confirming regulatory equivalence for international trade and compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can SI-B8V463B20WW directly replace SI-B8V26156CUS without circuit modifications?

A: No. The substitute operates at 45V forward voltage compared to 24.4V for the original part. Power supply design and current limiting circuits must be re-evaluated and adjusted accordingly. The higher luminous flux output (7570 lm vs. 3607 lm) also requires thermal management assessment.

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

A: Yes. Both modules specify 3000K color temperature and CRI 80, ensuring identical warm white color output and color rendering performance.

Q: What are the physical compatibility considerations?

A: The substitute is twice the length (1120 mm vs. 560 mm) and 1.8 mm shorter in height (3.70 mm vs. 5.50 mm). Mechanical mounting structures, optical housings, and form factor designs must accommodate these dimensional changes.

Q: Why is the substitute part classified as Active while the main part is Obsolete?

A: The SI-B8V463B20WW represents a newer generation (V Gen3 series) within the SI-B8 product family. Active status indicates current manufacturing, ongoing technical support, and long-term availability, making it suitable for new designs and legacy system support.

Q: Are packaging and regulatory classifications the same?

A: Yes. Both parts are supplied in Tray packaging and carry identical export control (ECCN EAR99) and tariff classifications (HTSUS 8541.41.0000).

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

A: The substitute delivers 166 lm/W compared to 132 lm/W for the main part, representing approximately 26% higher luminous efficacy at test conditions.

Q: Can I use a shorter length substitute if the application requires the original 560 mm dimension?

A: The SI-B8V463B20WW is available only in 1120 mm length. For applications requiring the original 560 mm dimension, the substitute cannot be used without mechanical redesign or segmentation of the light strip.
