Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SI-B8V342B2CUS is determined by the following critical parameters:

Primary Compatibility Criteria:

• Shared base product number (SI-B8) indicating mechanical and electrical platform compatibility
• Identical CCT specification (3000K) ensuring color temperature consistency
• Linear light strip configuration maintaining form factor equivalence
• Identical physical length (1120.00mm L x 18.00mm W) for mechanical fit
• Flat lens type consistency
• Matching CRI value (80) for color rendering performance
• Identical ECCN and HTSUS classifications for regulatory compliance

Secondary Compatibility Factors:

• Forward voltage within acceptable operating range for driver circuit compatibility
• Current specifications within standard power supply capability ranges
• Active product status ensuring ongoing availability and supply chain support

The SI-B8V243B20WW qualifies as a direct substitute based on these parameters, representing an evolution within the same product family (V Gen3) with maintained mechanical dimensions and electrical operating characteristics.

Engineering Selection Recommendations

The SI-B8V243B20WW is the appropriate substitute for the obsolete SI-B8V342B2CUS based on the following engineering criteria:

Product Status Alignment: The substitute is classified as active, ensuring continued manufacturing support, supply chain availability, and technical documentation access. The original part's obsolete status creates supply risk for ongoing production and field replacement requirements.

Regulatory and Compliance Equivalence: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export control and tariff treatment.

Mechanical Compatibility: Identical length (1120.00mm) and width (18.00mm) dimensions ensure direct mechanical fit within existing fixtures and assemblies. The substitute's reduced height (3.70mm versus 5.50mm) represents a design improvement that maintains compatibility while reducing overall module profile.

Electrical Operating Characteristics: The substitute operates at a lower forward voltage (44.4V versus 46.4V) and lower test current (530mA versus 700mA), both within standard driver circuit tolerance ranges. The substitute's higher maximum current rating (1.8A versus 900mA) provides additional operational headroom.

Photometric Performance: Both components maintain identical CCT (3000K) and CRI (80) specifications, ensuring color consistency in lighting applications. The substitute demonstrates improved luminous efficacy (177 lm/W versus 165 lm/W), representing a 7.3% efficiency gain.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8V243B20WW be used as a direct replacement for the SI-B8V342B2CUS in existing designs?

A: Yes. Both components share identical mechanical dimensions (length and width), identical color temperature (3000K), identical CRI (80), and identical lens type (flat). The substitute's lower profile (3.70mm versus 5.50mm) is compatible with existing mechanical assemblies and may provide design advantages in space-constrained applications.

Q: What is the difference in electrical operating requirements?

A: The substitute operates at a lower forward voltage (44.4V versus 46.4V) and lower test current (530mA versus 700mA). Standard LED driver circuits designed for the original part will operate the substitute within normal parameters. The 2.0V voltage difference is within typical driver circuit tolerance ranges.

Q: How do the luminous output specifications compare?

A: The original part produces 5360 lm at 700mA test current, while the substitute produces 4160 lm at 530mA test current. These measurements are taken at different operating currents. The substitute demonstrates higher luminous efficacy (177 lm/W versus 165 lm/W), indicating improved energy efficiency.

Q: Are there any packaging or supply chain differences?

A: The original part is obsolete with no ongoing manufacturing. The substitute is actively manufactured by Samsung Semiconductor, Inc., ensuring reliable supply chain access and technical support. Current inventory for the substitute is 987 pieces.

Q: Do both components have the same regulatory classifications?

A: Yes. Both components are classified under ECCN EAR99 and HTSUS 8541.41.0000, confirming identical export control and tariff treatment.

Q: What is the significance of the viewing angle specification on the substitute?

A: The substitute specifies a 118° viewing angle, providing additional optical performance data. The original part does not specify this parameter. This specification indicates the angular range over which the light output remains within acceptable intensity levels.

Q: Are there any moisture sensitivity considerations?

A: The original part is classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The substitute is classified as Not Applicable for MSL, indicating equivalent or superior moisture handling characteristics.
