SI-B8U522B2CUS LED Module V-Series Gen2 Equivalent & Substitute Parts

Part Overview

The SI-B8U522B2CUS is a Samsung Semiconductor LED Module V-Series Gen2 linear light strip designed for white, cool lighting applications at 3500K color temperature. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration. The module delivers 8410 lumens at typical operating conditions with a forward voltage of 46.5V and operates at 1.12A test current.

Due to its obsolete product status, sourcing direct replacements from current manufacturing inventory is required for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8U522B2CUS is determined by the following critical parameters:

Mandatory Matching Criteria:

• Base Product Number: SI-B8 (ensures mechanical and electrical platform compatibility)
• Configuration: Linear Light Strip (form factor requirement)
• CCT (Color Temperature): 3500K (photometric specification)
• Lens Type: Flat (optical interface requirement)
• Length: 1120.00 mm (dimensional constraint)
• Width: 18.00 mm (dimensional constraint)

Allowable Variation Parameters:

• Series generation (V-Series Gen2 to V-Series Gen3 permitted)
• Product Status (Obsolete to Active transition acceptable)
• Luminous Flux (within functional range for application)
• Current ratings (forward voltage and maximum current may vary within system design tolerance)
• Height (3.70 mm vs. 5.50 mm represents design evolution)
• Packaging format (Bulk to Tray represents inventory management change)
• Viewing Angle (addition of specification in newer generation)

The SI-B8U463B20WW qualifies as a direct substitute based on shared base platform, identical dimensional length and width, matching color temperature, and compatible optical properties.

Engineering Selection Recommendations

Primary Substitute: SI-B8U463B20WW

The SI-B8U463B20WW is the qualified substitute for the obsolete SI-B8U522B2CUS based on the following engineering criteria:

Compliance and Status:

• The substitute is in active production status, ensuring long-term availability and supply chain continuity
• Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory compliance
• Both parts share the SI-B8 base product number, confirming mechanical and electrical platform compatibility

Dimensional Compatibility:

• Length and width dimensions are identical (1120.00 mm × 18.00 mm), ensuring direct mechanical fit in existing fixtures and assemblies
• Height reduction from 5.50 mm to 3.70 mm represents a design optimization that may improve thermal performance and reduce overall system profile
• Flat lens type is maintained across both generations

Electrical and Photometric Performance:

• Identical CCT specification (3500K) ensures color temperature consistency
• Identical CRI (80) maintains color rendering characteristics
• Luminous flux range of the substitute (7150–8440 lm) encompasses the main part's typical output (8410 lm)
• Forward voltage reduction (46.5 V to 45 V) and improved efficiency (161 to 169 lm/W) indicate design advancement
• Test current is comparable (1.12 A vs. 1.01 A), with higher maximum current rating (2.02 A) providing operational margin

Packaging Consideration:

• Packaging change from Bulk to Tray reflects standard inventory management practices and does not affect component functionality

The SI-B8U463B20WW is suitable for direct substitution in applications requiring the SI-B8U522B2CUS specifications.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8U463B20WW be used as a direct replacement for the SI-B8U522B2CUS?

A: Yes. Both parts share the SI-B8 base product number, identical length and width dimensions (1120.00 mm × 18.00 mm), matching color temperature (3500K), identical CRI (80), and flat lens type. The substitute is in active production, whereas the main part is obsolete.

Q: What is the significance of the height difference (5.50 mm vs. 3.70 mm)?

A: The height reduction in the substitute represents a design optimization in the V-Series Gen3 generation. This 1.80 mm reduction may improve thermal dissipation and reduce overall system profile. Mechanical fit must be verified in applications with height-constrained mounting.

Q: How do the electrical specifications compare?

A: The substitute operates at slightly lower forward voltage (45 V vs. 46.5 V) and lower test current (1.01 A vs. 1.12 A), while delivering comparable luminous flux within the specified range (7150–8440 lm vs. 8410 lm typical). The substitute has a higher maximum current rating (2.02 A vs. 1.35 A), providing greater operational headroom.

Q: Is the efficiency improvement significant?

A: The substitute demonstrates 4.9% higher efficiency (169 lm/W vs. 161 lm/W), indicating improved optical and thermal design in the Gen3 generation. This translates to lower power consumption for equivalent light output.

Q: Why is the packaging different (Bulk vs. Tray)?

A: Packaging format change reflects standard inventory management practices between product generations. Bulk packaging is typically used for legacy products, while Tray packaging is standard for active production. This does not affect component performance or functionality.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent regulatory treatment and export compliance.

Q: What is the viewing angle specification for the substitute?

A: The SI-B8U463B20WW specifies a 118° viewing angle. The main part does not include a viewing angle specification. This addition in the newer generation provides defined optical performance characteristics.

Q: Can the substitute be used in existing designs without modification?

A: Mechanical fit is compatible due to identical length and width. The height reduction (1.80 mm) must be evaluated for applications with tight vertical clearance. Electrical compatibility is confirmed through comparable voltage and current specifications. System-level validation is recommended for critical applications.
