Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8U52256CUS is determined by the following critical parameters:

Primary Substitution Criteria:

• Base Product Number: SI-B8 (common platform)
• Configuration: Linear Light Strip
• CCT (Correlated Color Temperature): 3500K
• CRI (Color Rendering Index): 80
• Lens Type: Flat
• Manufacturer: Samsung Semiconductor, Inc.

Secondary Compatibility Factors:

• Voltage and current operating ranges must accommodate system design requirements
• Luminous flux output and efficiency (lm/W) determine brightness performance
• Physical dimensions affect mechanical fit and thermal management
• Product status (Active vs. Obsolete) determines long-term availability

The substitute part SI-B8U923B20WW shares the same base product platform (SI-B8), identical CCT and CRI specifications, matching configuration, and identical lens type. This part represents an evolution within the V-Series family (Gen3 vs. Gen2) with active product status, ensuring procurement continuity and improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SI-B8U52256CUS is classified as obsolete. The substitute part SI-B8U923B20WW carries active product status, ensuring availability for current and future procurement cycles. Active status indicates ongoing manufacturing support, quality assurance, and supply chain reliability.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS code (8541.41.0000) classifications, confirming regulatory equivalence for export and tariff purposes.

Performance Characteristics: The substitute part delivers 15360 lumens compared to 8410 lumens in the main part, representing an 82.6% increase in luminous flux output. Efficiency improves from 161 lm/W to 169 lm/W. These performance gains result from V-Series Gen3 technology advancement while maintaining identical color temperature (3500K) and color rendering index (80).

Electrical Operating Parameters: The substitute part operates at 2.02A test current versus 1.12A for the main part, with forward voltage of 45V compared to 46.5V. System power supply design must accommodate the increased current draw. The lower forward voltage provides marginal electrical advantage.

Physical Dimensions: The substitute part measures 1120.00 mm in length (double the main part) with reduced height (3.70 mm vs. 5.50 mm). Width remains constant at 39.80 mm. Mechanical integration requires verification of available mounting space and thermal management provisions.

Moisture Sensitivity: The main part specifies MSL 1 (Unlimited). The substitute part lists MSL as Not Applicable, indicating enhanced moisture resistance or different packaging classification.

Frequently Asked Questions (FAQ)

Q: Can SI-B8U923B20WW directly replace SI-B8U52256CUS in existing designs?

A: Direct replacement requires system-level evaluation. Both parts share identical CCT (3500K), CRI (80), configuration (linear light strip), and lens type (flat). However, the substitute part operates at higher current (2.02A vs. 1.12A), requires different power supply specifications, and has different physical dimensions (1120 mm length vs. 560 mm, and 3.70 mm height vs. 5.50 mm). Mechanical fit and electrical compatibility must be confirmed before implementation.

Q: What are the key differences between V-Series Gen2 and V-Series Gen3?

A: The Gen3 substitute part delivers significantly higher luminous flux (15360 lm vs. 8410 lm) and improved efficiency (169 lm/W vs. 161 lm/W). Gen3 also features a 118° viewing angle specification not provided for Gen2. Physical profile is lower (3.70 mm vs. 5.50 mm height). Both generations maintain identical color specifications (3500K CCT, 80 CRI) and base product platform (SI-B8).

Q: Why is the substitute part longer (1120 mm vs. 560 mm)?

A: The increased length reflects Gen3 design optimization for linear light strip applications. The substitute part achieves higher total luminous flux through extended emitting surface rather than increased current density. This design approach may provide improved thermal distribution and efficiency characteristics.

Q: Are there packaging differences between these parts?

A: The main part packaging is listed as "-" (not specified). The substitute part is packaged in Tray format. Packaging differences may affect handling, storage, and assembly processes. Confirm compatibility with existing assembly and logistics procedures.

Q: What is the significance of MSL classification differences?

A: The main part specifies MSL 1 (Unlimited moisture sensitivity level). The substitute part lists MSL as Not Applicable, indicating either enhanced moisture resistance or different classification methodology. This may affect storage conditions and shelf-life management. Consult Samsung technical documentation for specific handling requirements.

Q: Are both parts compliant with the same export and tariff regulations?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS code (8541.41.0000), confirming regulatory equivalence for export control and tariff classification purposes.

Q: What inventory status should influence procurement decisions?

A: The main part (SI-B8U52256CUS) shows 707 pieces in stock but carries obsolete status, indicating no future manufacturing. The substitute part (SI-B8U923B20WW) shows 963 pieces in stock with active product status, ensuring long-term availability and supply continuity.
