Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8T342B2CUS is determined by the following critical parameters:

Primary Substitution Criteria:

• Color temperature: 4000K (neutral white)
• Configuration: Linear light strip
• Color: White, Neutral
• CRI: 80 minimum
• Base product family: SI-B8 series
• Lens type: Flat
• Physical dimensions: 1120.00mm L x 18.00mm W

The SI-B8T243B20WW qualifies as a substitute part because it maintains identical color temperature (4000K), configuration (linear light strip), color specification (white, neutral), CRI rating (80), base product number (SI-B8), lens type (flat), and footprint dimensions (1120.00mm L x 18.00mm W). The substitute represents an evolution to V Gen3 technology with active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The SI-B8T243B20WW is the designated substitute for the obsolete SI-B8T342B2CUS. Selection of the substitute part is supported by the following factors:

Product Status: The SI-B8T243B20WW maintains active product status with Samsung Semiconductor, Inc., ensuring continued manufacturing support, quality assurance, and supply chain availability. The main part SI-B8T342B2CUS is classified as obsolete, making the substitute necessary for ongoing production and new design implementations.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent regulatory and trade compliance status.

Functional Equivalence: The substitute maintains the same color temperature (4000K), color rendering index (80), configuration (linear light strip), and physical footprint (1120.00mm L x 18.00mm W), ensuring compatibility with existing mechanical and optical designs.

Performance Characteristics: The SI-B8T243B20WW demonstrates improved luminous efficacy (187 lm/W versus 173 lm/W) and reduced profile height (3.70mm versus 5.50mm), representing technological advancement within the V-Series product family.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8T243B20WW directly replace the SI-B8T342B2CUS in existing applications?

A: The SI-B8T243B20WW is functionally equivalent for applications requiring 4000K neutral white linear light strips with 80 CRI. Both parts share identical color temperature, configuration, footprint length and width, and color rendering specifications. The substitute features a reduced height (3.70mm versus 5.50mm), which may require mechanical design verification for applications with strict height constraints.

Q: What are the key differences between these two parts?

A: The primary differences are series generation (V-Series Gen2 versus V Gen3), product status (obsolete versus active), height profile (5.50mm versus 3.70mm), and test current specifications (700mA versus 530mA). The substitute delivers higher luminous efficacy (187 lm/W versus 173 lm/W) and supports higher maximum current (1.8A versus 900mA).

Q: Are there packaging differences between the main part and substitute?

A: Yes. The SI-B8T342B2CUS is supplied in bulk packaging, while the SI-B8T243B20WW is supplied in tray packaging. This difference affects handling, storage, and integration into production workflows but does not impact electrical or optical performance.

Q: What is the impact of the lower luminous flux in the substitute part?

A: The SI-B8T243B20WW delivers 4400 lumens at its test current (530mA) compared to 5620 lumens for the main part at 700mA. However, the substitute achieves superior luminous efficacy (187 lm/W), indicating more efficient light generation. Applications requiring specific lumen output should evaluate whether the substitute's performance at its rated current meets system requirements.

Q: Are the forward voltage specifications compatible with existing driver circuits?

A: The forward voltage difference is minimal (46.4V versus 44.4V), representing a 2-volt reduction in the substitute part. Existing driver circuits designed for the main part should be evaluated to confirm compatibility with the lower forward voltage specification of the substitute.

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

A: The SI-B8T243B20WW specifies a viewing angle of 118°. The main part SI-B8T342B2CUS does not provide a viewing angle specification in the available data.
