SI-B8R342B2CUS LED Module Equivalent & Substitute Parts

Part Overview

The SI-B8R342B2CUS is a Samsung Semiconductor LED Module V-Series Gen2 linear light strip with cool white output at 5000K color temperature. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The module delivers 5690 lumens at typical operating conditions with a forward voltage of 46.4V and operates at 700mA test current.

Due to its obsolete status, the SI-B8R342B2CUS requires substitution with active production alternatives that maintain functional compatibility within the V-Series LED module family.

Substitute Part Grouping Explanation

Substitution of the SI-B8R342B2CUS is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Color Temperature: 5000K (cool white) - must match
• Color Rendering Index: 80 - must match
• Configuration: Linear Light Strip - must match
• Lens Type: Flat - must match
• Physical Dimensions: 1120.00mm L × 18.00mm W - must match
• Base Product Number: SI-B8 - must match
• Packaging: Tray - must match

Secondary Compatibility Factors:

• Forward Voltage (Vf): Similar range acceptable with power supply adjustment
• Current ratings: May vary within design envelope
• Luminous Flux: May vary based on efficiency improvements
• Product Status: Active production preferred over obsolete

The SI-B8R243B20WW meets all primary substitution criteria while offering active product status and improved efficiency characteristics.

Engineering Selection Recommendations

Primary Recommendation: SI-B8R243B20WW

The SI-B8R243B20WW is the direct substitute for the obsolete SI-B8R342B2CUS based on the following engineering factors:

1. Product Status: The substitute is in active production, ensuring long-term availability and supply chain continuity. The main part is obsolete and no longer manufactured.

2. Functional Equivalence: Both parts share identical specifications for color temperature (5000K), color rendering index (80), configuration (linear light strip), lens type (flat), and physical footprint (1120 × 18mm).

3. Compliance and Certifications: Both parts carry identical export classification (EAR99) and tariff codes (8541.41.0000), ensuring regulatory compatibility.

4. Electrical Compatibility: The forward voltage difference of 2V (46.4V vs. 44.4V) is within acceptable tolerance for standard LED power supply designs. The substitute operates at lower test current (530mA vs. 700mA) with improved efficiency (187 lm/W vs. 175 lm/W).

5. Mechanical Compatibility: The substitute maintains identical length and width dimensions. The reduced height (3.70mm vs. 5.50mm) provides a lower profile, which is advantageous for space-constrained applications and does not compromise compatibility.

6. Packaging: Identical tray packaging ensures compatibility with existing handling and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8R243B20WW be used as a direct replacement for the SI-B8R342B2CUS?

A: Yes. Both parts are Samsung Semiconductor SI-B8 base product family linear light strips with identical color temperature (5000K), color rendering index (80), lens type (flat), and physical footprint (1120 × 18mm). The substitute is in active production, addressing the obsolescence of the main part.

Q: What is the difference in luminous flux between these parts?

A: The SI-B8R342B2CUS produces 5690 lumens at 700mA test current, while the SI-B8R243B20WW produces 4400 lumens at 530mA test current. The substitute achieves higher efficiency (187 lm/W vs. 175 lm/W), indicating improved LED technology in the newer generation.

Q: Will the forward voltage difference affect my power supply?

A: The forward voltage difference is 2V (46.4V vs. 44.4V). Standard LED power supplies designed for the SI-B8R342B2CUS will operate the SI-B8R243B20WW within acceptable parameters. No power supply redesign is required.

Q: Are the physical dimensions identical?

A: The length and width are identical (1120 × 18mm). The substitute has a reduced height of 3.70mm compared to 5.50mm, providing a lower profile. This does not affect compatibility and may be advantageous in space-constrained designs.

Q: What is the maximum current rating for the substitute?

A: The SI-B8R243B20WW supports a maximum current of 1.8A, compared to 900mA for the main part. This provides greater operational flexibility and headroom for the substitute.

Q: Are the packaging and handling requirements the same?

A: Yes. Both parts are supplied in trays with identical moisture sensitivity level (not applicable) and require the same handling and storage procedures.

Q: Can I use the SI-B8R243B20WW in existing designs without modification?

A: Yes. The substitute maintains mechanical and electrical compatibility with existing designs. The identical footprint, flat lens type, and compatible forward voltage ensure drop-in compatibility. The improved efficiency and lower profile are additional benefits.

Q: What is the viewing angle of the substitute?

A: The SI-B8R243B20WW specifies a viewing angle of 118°. The main part does not specify this parameter, but both use flat lens types typical of linear light strips.

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

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory compliance in the same jurisdictions.
