LED Module SI-B8U14156SWW Equivalent & Substitute Parts

Part Overview

The SI-B8U14156SWW is a Samsung Semiconductor LED Module classified as a warm white linear light strip with a correlated color temperature (CCT) of 3500K. This component is designed for LED lighting applications requiring COB (Chip-on-Board) engine modules with linear strip configuration. The part is designated as "Not For New Designs," indicating it has reached end-of-life status in Samsung's product portfolio. For ongoing production requirements or new system designs, equivalent substitute parts meeting the same electrical and mechanical specifications are necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8U14156SWW is determined by strict alignment of the following critical parameters:

Color and CCT Specification: The substitute part must be a warm white linear light strip with CCT of 3500K and CRI of 80 to maintain color consistency in lighting applications.

Configuration and Form Factor: The substitute must be a linear light strip LED module with comparable physical dimensions (length approximately 560mm, width approximately 24mm, height approximately 6mm) and flat lens type.

Electrical Characteristics: The substitute must operate within compatible voltage and current ranges. Forward voltage (Vf) and maximum current ratings must support the same driver and power supply configurations.

Luminous Output: The substitute must deliver luminous flux output within the range of the original specification to maintain lighting performance.

Compliance and Status: The substitute must hold active product status and maintain equivalent RoHS and regulatory compliance certifications.

The BXEB-L0560Z-35E2000-C-B3 from Bridgelux meets all these criteria and is classified as an equivalent substitute.

Engineering Selection Recommendations

Primary Substitute: BXEB-L0560Z-35E2000-C-B3 (Bridgelux)

The Bridgelux BXEB-L0560Z-35E2000-C-B3 is the qualified equivalent substitute for the Samsung SI-B8U14156SWW. Selection is based on the following engineering criteria:

Product Status: The Bridgelux part holds Active product status, whereas the Samsung part is designated "Not For New Designs." This makes the Bridgelux component the appropriate choice for ongoing production and new system designs.

Electrical Compatibility: Both parts operate at comparable voltage and current levels. The Bridgelux part exhibits a forward voltage of 19.5V compared to 17.6V for the Samsung part. This 1.9V difference is within typical driver tolerance ranges for LED module applications and does not preclude direct substitution in standard lighting driver circuits.

Optical Performance: The Bridgelux substitute delivers 2390 lm compared to 2210 lm for the original part, representing a 8.1% increase in luminous flux output. Both parts maintain identical CCT (3500K) and CRI (80) specifications, ensuring color consistency. The Bridgelux part provides a 120° viewing angle versus 115° for the Samsung part, offering marginally improved light distribution.

Efficiency: The Bridgelux part achieves 175 lm/W compared to 157 lm/W for the Samsung part, indicating superior energy efficiency.

Mechanical Compatibility: Physical dimensions are nearly identical. Length and width match within 0.3mm. Height difference of 0.3mm is negligible for linear strip mounting applications.

Regulatory Compliance: Both parts maintain RoHS compliance. The Bridgelux part carries ROHS3 certification, representing current regulatory alignment. Both parts have MSL rating of 1 (Unlimited), indicating identical moisture handling requirements.

Packaging Consideration: The Samsung part is supplied in Tray packaging, while the Bridgelux substitute is supplied in Bulk packaging. Procurement and inventory management processes must account for this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the BXEB-L0560Z-35E2000-C-B3 directly replace the SI-B8U14156SWW in existing designs?

A: Yes, the Bridgelux part is a direct electrical and mechanical substitute. The 1.9V forward voltage difference (19.5V vs. 17.6V) is within standard driver tolerance for LED module applications. Physical dimensions are compatible within 0.3mm tolerance. No circuit redesign is required.

Q: What is the impact of the higher luminous flux output (2390 lm vs. 2210 lm) from the substitute part?

A: The 8.1% increase in luminous flux output results in proportionally brighter illumination. In applications where the original part met brightness requirements with margin, the substitute will provide equivalent or enhanced performance. In brightness-critical applications, driver current may require adjustment to match original light output specifications.

Q: Are there any thermal management differences between the two parts?

A: The input parameters do not include thermal resistance or junction temperature data for either part. Thermal management compatibility must be verified through detailed thermal analysis or manufacturer datasheets if thermal performance is critical to the application.

Q: Does the 5° difference in viewing angle (115° vs. 120°) affect optical design?

A: The Bridgelux substitute provides a 5° wider viewing angle, resulting in slightly broader light distribution. For applications requiring specific beam geometry, optical design verification is necessary. In general lighting applications, this difference is negligible.

Q: What are the packaging implications of switching from Tray to Bulk packaging?

A: Tray packaging typically accommodates smaller order quantities and provides individual part protection. Bulk packaging is suited for higher-volume procurement. Inventory management, handling procedures, and component protection during storage and transport must be adjusted accordingly.

Q: Are both parts suitable for new product designs?

A: The Samsung SI-B8U14156SWW is designated "Not For New Designs," indicating end-of-life status. The Bridgelux BXEB-L0560Z-35E2000-C-B3 holds Active product status and is the appropriate choice for new designs requiring warm white 3500K linear LED modules.

Q: What is the significance of the MSL rating of 1 (Unlimited) for both parts?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These parts do not require special moisture control during storage, handling, or assembly. Standard warehouse conditions are acceptable.

Q: How do the RoHS compliance levels differ between the parts?

A: The Samsung part is RoHS Compliant (RoHS 2). The Bridgelux part is ROHS3 Compliant, representing alignment with current EU regulatory requirements. Both parts meet hazardous substance restrictions. ROHS3 compliance indicates the Bridgelux part is current with the latest regulatory standards.
