LED Module SI-B8V301B2CUS Equivalent & Substitute Parts

Part Overview

The SI-B8V301B2CUS is a Samsung Semiconductor LED Module classified as an obsolete product. This linear light strip module operates at 3000K color temperature with warm white output, designed for LED lighting applications requiring COB (Chip-on-Board) engine configurations. Due to its obsolete product status, equivalent substitute parts are necessary for ongoing procurement and system integration where this module is specified in legacy designs or where inventory depletion requires alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8V301B2CUS is determined by the following critical parameters that must align for functional equivalence:

Mechanical Compatibility:

• Physical dimensions (length, width, height) must match or be compatible with mounting infrastructure
• Configuration type must remain Linear Light Strip
• Base product number SI-B8 indicates family compatibility

Optical Specifications:

• Color temperature (CCT) at 3000K defines the warm white output requirement
• CRI of 80 establishes color rendering performance baseline
• Viewing angle affects light distribution characteristics

Electrical Parameters:

• Forward voltage (Vf) and current ratings determine power supply compatibility
• Luminous flux output establishes brightness performance
• Lumens/Watt efficiency indicates energy conversion performance

Regulatory & Environmental:

• RoHS Compliance status must be maintained
• MSL rating ensures moisture handling compatibility
• Product status (Obsolete) indicates end-of-life status requiring alternatives

The substitute part SI-B8V342B2CUS shares the SI-B8 base product number, maintains identical physical dimensions, operates at the same 3000K color temperature, and preserves CRI 80 performance, establishing it as a qualified substitute within the Samsung LED module family.

Parameter Comparison

Engineering Selection Recommendations

Mechanical Fit: Both the main part and substitute share identical physical dimensions (1120.00 mm L x 18.00 mm W x 5.50 mm H), ensuring direct mechanical compatibility in existing mounting structures designed for the SI-B8V301B2CUS.

Optical Performance: Both parts maintain 3000K color temperature and CRI 80, preserving color rendering characteristics required for warm white lighting applications. The substitute delivers higher luminous flux (5360 lm vs. 4090 lm), providing increased brightness output.

Electrical Considerations: The substitute operates at higher forward voltage (46.4V vs. 25.4V) and lower test current (700mA vs. 1.26A). Power supply specifications must be verified for compatibility with the substitute's electrical requirements. Total power consumption differs between parts and must be evaluated against system design parameters.

Regulatory Compliance: Both parts maintain RoHS Compliance status and MSL 1 (Unlimited) rating, ensuring equivalent environmental and moisture handling requirements.

Product Status: Both parts are classified as Obsolete. Selection between them should prioritize availability, inventory status, and power supply compatibility within the application system.

Frequently Asked Questions (FAQ)

Q: Can SI-B8V342B2CUS directly replace SI-B8V301B2CUS in existing designs?

A: Mechanical and optical compatibility is confirmed through identical dimensions and color temperature specifications. However, electrical compatibility must be verified. The substitute requires a 46.4V power supply versus the original 25.4V. Existing power supply infrastructure must support this higher voltage requirement before substitution.

Q: What are the key differences between these two LED modules?

A: The primary differences are electrical and efficiency-related. SI-B8V342B2CUS operates at higher forward voltage (46.4V) with lower test current (700mA) compared to SI-B8V301B2CUS (25.4V, 1.26A). The substitute achieves higher luminous flux (5360 lm vs. 4090 lm) and superior efficiency (165 lm/W vs. 128 lm/W). Physical dimensions and color specifications remain identical.

Q: Are both parts still available for procurement?

A: Both parts are classified as Obsolete. Current inventory availability should be confirmed with the supplier. SI-B8V301B2CUS shows 1341 pcs in stock, while SI-B8V342B2CUS shows 1079 pcs in stock at the time of this reference.

Q: What does the SI-B8 base product number indicate?

A: The SI-B8 base product number identifies both parts as members of the same Samsung LED module family. This designation indicates design lineage and compatibility within the broader product ecosystem, though individual variants (V301B2CUS vs. V342B2CUS) have distinct electrical and performance characteristics.

Q: How do packaging differences affect selection?

A: SI-B8V301B2CUS is supplied in Tray packaging, while SI-B8V342B2CUS is supplied in Bulk packaging. Packaging selection depends on handling, storage, and assembly process requirements. Both maintain identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the significance of the 3000K color temperature specification?

A: The 3000K color temperature defines warm white light output, suitable for applications requiring warm-toned illumination. Both parts maintain this specification, ensuring consistent color appearance in applications where warm white output is specified.

Q: Why is CRI 80 important for this application?

A: CRI (Color Rendering Index) of 80 indicates the module's ability to accurately reproduce colors under its illumination. Both parts maintain this rating, ensuring equivalent color rendering performance for applications where color accuracy is a design requirement.
