SI-B8V522B2CUS LED Module Equivalent & Substitute Parts

Part Overview

The SI-B8V522B2CUS is a Samsung Semiconductor LED Module V-Series Gen2 linear light strip designed for white, cool lighting applications at 3000K color temperature. This component is classified as Obsolete and is no longer in active production. Due to its obsolete status, sourcing new inventory from primary channels is limited, making identification of functionally equivalent substitute parts essential for ongoing system design and procurement.

The SI-B8V522B2CUS operates at a forward voltage of 46.5V with a typical luminous flux of 8300lm and delivers 159 lm/W efficiency at test conditions. Its linear light strip configuration with flat lens and 1120mm length makes it suitable for extended lighting applications requiring consistent color rendering.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SI-B8V522B2CUS is determined by the following critical parameters that must align between the main part and substitute:

Primary Substitution Criteria:

• Base Product Number: Both parts must share the SI-B8 base platform to ensure mechanical and electrical compatibility
• Configuration: Linear light strip format must be maintained
• Color Temperature (CCT): 3000K specification must be preserved for color consistency
• Lens Type: Flat lens configuration must be retained
• Physical Dimensions: Length (1120mm), width (18mm), and height must be compatible with existing mechanical assemblies
• CRI (Color Rendering Index): Minimum CRI of 80 must be maintained for color rendering quality
• Electrical Compatibility: Forward voltage and current ratings must be compatible with existing driver circuits and power supplies

The substitute part SI-B8V463B20WW meets these criteria as a Samsung Semiconductor LED Module from the V Gen3 series, representing an active product line evolution that maintains the SI-B8 base platform and core functional specifications while offering improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SI-B8V463B20WW is a direct functional substitute for the obsolete SI-B8V522B2CUS based on the following engineering factors:

Electrical Compatibility: The substitute operates at 45V forward voltage compared to the main part's 46.5V, representing a 1.5V differential. This variance is within the tolerance range of standard LED driver circuits and does not require circuit redesign. The test current of 1.01A versus 1.12A indicates slightly lower power consumption at nominal operation, with the substitute's maximum current rating of 2.02A providing additional operational headroom.

Optical Performance: Both parts maintain identical 3000K color temperature and 80 CRI specifications, ensuring color consistency in lighting applications. The substitute delivers 7570lm compared to the main part's 8300lm, representing 91.2% of the original luminous flux. The substitute achieves 166 lm/W efficiency versus 159 lm/W, indicating improved energy conversion despite the lower absolute lumen output.

Mechanical Compatibility: Physical dimensions are identical in length (1120mm) and width (18mm), ensuring compatibility with existing mechanical assemblies and fixtures. The substitute's reduced height of 3.70mm versus 5.50mm provides a lower profile, which may offer advantages in space-constrained applications without requiring mechanical redesign.

Product Status and Compliance: The SI-B8V463B20WW is classified as Active, ensuring ongoing availability and supply chain continuity. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory and trade compliance. The substitute's elimination of MSL requirements simplifies handling and storage procedures.

Packaging Consideration: The substitute is supplied in Tray packaging versus Bulk packaging for the main part. This change may affect inventory management and component handling procedures but does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8V463B20WW directly replace the SI-B8V522B2CUS in existing designs?

A: Yes, the SI-B8V463B20WW is a direct functional substitute. Both parts share the SI-B8 base platform, identical physical dimensions (length and width), matching color temperature (3000K), and equivalent CRI (80). The 1.5V forward voltage difference and reduced height are compatible with standard LED driver circuits and mechanical assemblies.

Q: What is the impact of the 730lm luminous flux reduction?

A: The substitute delivers 7570lm versus the main part's 8300lm, representing 91.2% of the original output. This reduction must be evaluated against specific application requirements. For applications where full original brightness is critical, this difference requires assessment. The substitute's improved efficiency (166 lm/W versus 159 lm/W) partially offsets the absolute lumen reduction.

Q: Are there electrical circuit modifications required for substitution?

A: No circuit modifications are required. The 1.5V forward voltage difference (45V versus 46.5V) falls within the tolerance range of standard LED driver circuits. The substitute's test current of 1.01A versus 1.12A indicates lower power consumption, and the maximum current rating of 2.02A provides operational margin.

Q: How does the reduced height (3.70mm versus 5.50mm) affect mechanical integration?

A: The lower profile of the substitute may provide advantages in space-constrained applications. Existing mechanical fixtures and assemblies designed for the main part will accommodate the substitute without modification. The identical length and width ensure drop-in compatibility.

Q: What is the significance of the packaging change from Bulk to Tray?

A: The packaging format change affects handling, storage, and inventory management procedures but does not impact functional performance or electrical characteristics. Tray packaging may offer improved component protection and organization compared to bulk packaging.

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

A: The SI-B8V463B20WW represents a newer generation (V Gen3) within the SI-B8 product family and is in active production. The obsolete status of the main part reflects its discontinuation from Samsung's product line. Substitution with an active product ensures long-term supply chain availability and support.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent regulatory and trade compliance. The substitute's elimination of MSL requirements simplifies handling procedures without affecting compliance status.

Q: What viewing angle specification does the substitute provide?

A: The SI-B8V463B20WW specifies a 118° viewing angle. The main part does not provide a viewing angle specification. This specification indicates the angular range over which the light output remains within acceptable intensity levels and may be relevant for specific optical design considerations.
