Substitute Part Grouping Explanation
Substitution of the SI-B8T301B2CUS is determined by the following critical parameters that must align for functional equivalence:
Primary Substitution Criteria:
- Configuration: Linear Light Strip (required match)
- Color: White, Neutral (required match)
- CCT: 4000K (required match)
- CRI: 80 (required match)
- Base Product Number: SI-B8 (same platform family)
- Dimensions: 1120.00mm L × 18.00mm W × 5.50mm H (required match)
- RoHS Compliance: RoHS Compliant (regulatory requirement)
- Manufacturer: Samsung Semiconductor, Inc. (original manufacturer)
Secondary Compatibility Parameters:
- Voltage and current characteristics must be evaluated for driver compatibility
- Luminous flux output may vary within acceptable application ranges
- Lumens per watt efficiency may differ between generations
- Packaging format (Tray vs. Bulk) affects handling and inventory management
The substitute part SI-B8T342B2CUS meets all primary substitution criteria while operating under different electrical parameters due to generational advancement in the V-Series Gen2 platform.

Engineering Selection Recommendations
Substitution Feasibility:
The SI-B8T342B2CUS is a valid substitute for the SI-B8T301B2CUS based on matching configuration, color, CCT, CRI, physical dimensions, and compliance certifications. Both parts are RoHS Compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent handling and storage requirements.
Electrical Parameter Differences:
The substitute part operates at higher forward voltage (46.4V vs. 25.4V) and lower test current (0.7A vs. 1.26A). This represents a generational advancement in the V-Series Gen2 platform with improved efficiency (173 lm/W vs. 135 lm/W). The substitute delivers higher luminous flux output (5620 lm vs. 4310 lm) at lower current draw.
Driver Compatibility Requirement:
Direct substitution requires verification that the existing LED driver or power supply can accommodate the higher forward voltage specification of the SI-B8T342B2CUS. Systems designed for 25.4V operation may require driver reconfiguration or replacement to operate at 46.4V.
Packaging Consideration:
The main part is supplied in Tray packaging, while the substitute is supplied in Bulk packaging. This affects inventory management and component handling procedures but does not impact electrical or optical performance.
Compliance Status:
Both parts are obsolete products. Selection between them should prioritize driver compatibility and available inventory levels. Both maintain full RoHS compliance and equivalent moisture sensitivity specifications.
Frequently Asked Questions (FAQ)
Q: Can SI-B8T342B2CUS directly replace SI-B8T301B2CUS without modifications?
A: Physical and optical compatibility is confirmed. However, electrical compatibility requires verification. The substitute operates at 46.4V forward voltage compared to 25.4V in the original part. Existing LED drivers must support this higher voltage specification. If the current driver is rated for 25.4V operation only, driver replacement or reconfiguration is necessary.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution is valid when the following parameters match: Configuration (Linear Light Strip), Color (White, Neutral), CCT (4000K), CRI (80), physical dimensions (1120mm × 18mm × 5.50mm), and compliance certifications (RoHS Compliant, MSL Level 1). The SI-B8T342B2CUS meets all these criteria.
Q: Why does the substitute part have different electrical specifications?
A: The SI-B8T342B2CUS represents a generational advancement in Samsung's LED module platform (V-Series Gen2 vs. LT-VB22B). The higher forward voltage and lower current draw reflect improved circuit design and efficiency optimization, delivering 30% higher luminous flux output while reducing current consumption by 44%.
Q: Are there packaging differences between these parts?
A: Yes. The SI-B8T301B2CUS is supplied in Tray packaging, while the SI-B8T342B2CUS is supplied in Bulk packaging. This affects component handling, storage, and inventory management procedures but does not impact electrical performance or optical characteristics.
Q: What is the inventory status for these parts?
A: The SI-B8T301B2CUS has 962 pieces in stock. The SI-B8T342B2CUS has 1225 pieces in stock. Both are classified as obsolete products, making current inventory levels critical for procurement planning.
Q: Are both parts RoHS compliant?
A: Yes. Both SI-B8T301B2CUS and SI-B8T342B2CUS are RoHS Compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory compliance and handling requirements.
Q: What efficiency improvement does the substitute provide?
A: The SI-B8T342B2CUS delivers 173 lumens per watt compared to 135 lumens per watt in the original part, representing a 28% efficiency improvement. This translates to higher light output (5620 lm vs. 4310 lm) at lower current consumption (0.7A vs. 1.26A at test conditions).
