Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-B8U14256SWW is determined by strict alignment across the following critical parameters:

Color and CCT Matching: The substitute part must deliver white, warm light at 3500K with 3-Step MacAdam Ellipse tolerance to ensure color consistency in end-user applications.

Configuration Requirement: The substitute must be a linear light strip configuration to maintain mechanical and optical compatibility with existing fixture designs.

Dimensional Compatibility: Physical dimensions (length, width, height) must fall within acceptable tolerance ranges to ensure proper mounting and thermal management in existing assemblies.

Electrical Parameters: Forward voltage (Vf) and maximum current ratings must be compatible with existing power supply and driver circuit designs. Variations in these parameters require circuit redesign.

Optical Performance: Luminous flux output, CRI, and viewing angle must be equivalent or superior to maintain lighting quality and distribution characteristics.

Regulatory Compliance: RoHS and MSL ratings must meet or exceed the original part specifications to ensure regulatory and environmental compliance.

Connector Compatibility: Presence of integrated connector features must be maintained or verified for mechanical assembly compatibility.

The BXEB-L0560Z-35E2000-C-B3 (Bridgelux EB Series™ Gen 2) qualifies as a substitute based on alignment across these critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The SI-B8U14256SWW carries a "Not For New Designs" designation from Samsung, indicating the product line has reached end-of-life status. The BXEB-L0560Z-35E2000-C-B3 maintains "Active" product status from Bridgelux, ensuring ongoing technical support, supply availability, and design continuity.

Regulatory Compliance: Both parts meet RoHS requirements. The Bridgelux substitute achieves ROHS3 compliance, representing a higher regulatory standard. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export and tariff treatment.

Electrical Parameter Alignment: The substitute part exhibits a forward voltage (Vf) of 19.5V compared to the original 17.6V, representing a 1.9V increase. This difference requires verification against existing power supply and driver circuit specifications. Maximum current ratings are comparable (1.4A vs. 1.44A), indicating compatible thermal design margins.

Optical Performance: The substitute delivers superior luminous flux (2390 lm vs. 2210 lm) and efficiency (175 lm/W vs. 157 lm/W). Both parts maintain identical CRI (80) and matching 3500K CCT specifications. The substitute provides a wider viewing angle (120° vs. 115°), which is compatible with the original application.

Mechanical Compatibility: Planar dimensions (length and width) are within tolerance (560.00 x 24.00 mm vs. 559.70 x 23.80 mm). The substitute height is 1.3mm lower (6.10 mm vs. 7.40 mm). This dimensional difference requires verification against fixture design constraints, thermal management requirements, and connector alignment specifications.

Moisture Sensitivity: Both parts carry MSL Level 1 (Unlimited), indicating identical storage and handling requirements with no moisture-related constraints.

Selection Path: For applications requiring immediate substitution, the BXEB-L0560Z-35E2000-C-B3 qualifies as a functional equivalent based on color, configuration, optical performance, and regulatory compliance. Circuit-level verification of the forward voltage difference and mechanical validation of the height reduction are required before final design release.

Frequently Asked Questions (FAQ)

Q: Can the BXEB-L0560Z-35E2000-C-B3 directly replace the SI-B8U14256SWW without circuit modifications?

A: Direct replacement requires verification of two parameters. The substitute's forward voltage (19.5V) is 1.9V higher than the original (17.6V). Existing power supply and driver circuits must be evaluated to confirm they can accommodate this voltage increase without exceeding maximum ratings or reducing efficiency. The height reduction (1.3mm) must be verified against fixture mechanical constraints and thermal management design.

Q: Are the color and brightness characteristics identical between these parts?

A: Both parts deliver white, warm light at 3500K with CRI 80, ensuring color consistency. The substitute provides higher luminous flux (2390 lm vs. 2210 lm) and efficiency (175 lm/W vs. 157 lm/W). This represents improved brightness output and energy efficiency, which is compatible with the original application intent.

Q: What is the significance of the "Not For New Designs" status on the Samsung part?

A: This designation indicates Samsung has discontinued active development, manufacturing, and technical support for the LT-S562F series. The part may become unavailable as existing inventory depletes. The Bridgelux substitute carries "Active" status, confirming ongoing availability and manufacturer support.

Q: Do both parts meet the same regulatory and environmental standards?

A: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The Bridgelux substitute achieves ROHS3 compliance, representing a higher regulatory standard. Both parts carry MSL Level 1 (Unlimited), indicating identical moisture sensitivity and storage requirements.

Q: What are the key differences in test conditions between the two parts?

A: The Samsung part is tested at 800mA and 50°C, while the Bridgelux substitute is tested at 700mA and 25°C. These different test conditions affect the reported luminous flux and efficiency values. Direct performance comparison requires normalization to identical test conditions or evaluation under actual application operating parameters.

Q: Are the physical dimensions compatible with existing fixtures designed for the SI-B8U14256SWW?

A: Planar dimensions (length and width) are within tolerance. The substitute is 1.3mm lower in height (6.10 mm vs. 7.40 mm). This reduction must be verified against fixture design constraints, including connector alignment, thermal interface requirements, and optical path specifications. Mechanical validation is required before production implementation.

Q: Does the substitute part include the connector feature specified in the original part?

A: The original part description specifies "With Connector" as a feature. The substitute part description does not explicitly list connector features. Connector compatibility must be verified directly with Bridgelux technical documentation or through physical sample evaluation before design release.

Q: What is the inventory status for both parts?

A: The Samsung SI-B8U14256SWW has 699 pieces available as new original stock. The Bridgelux BXEB-L0560Z-35E2000-C-B3 has 1084 pieces available as new original stock. Inventory levels should be confirmed with suppliers for current availability and lead time requirements.
