Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-B8U07128HWW are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Configuration: Linear Light Strip (identical form factor)
• Color Temperature: 3500K (3-Step MacAdam Ellipse tolerance)
• Color Rendering Index: 80 (minimum acceptable color accuracy)
• Lens Type: Flat (optical interface compatibility)
• Luminous Flux Range: Approximately 1090 lm ±10% (functional light output equivalence)
• Forward Voltage: Compatible with existing driver circuits (19.5V to 23.4V range acceptable for adjustable drivers)
• Current Rating: Maximum current ≥540mA (thermal headroom maintenance)
• Compliance: RoHS or equivalent environmental standards

The Bridgelux BXEB-L0280Z-35E1000-C-B3 meets all primary substitution criteria. Both modules are linear light strips with identical color temperature specification, matching CRI, flat lens configuration, and comparable physical dimensions. The substitute part demonstrates superior luminous flux (1195 lm vs. 1090 lm) and efficiency (175 lm/W vs. 155 lm/W), with adequate maximum current rating (700mA vs. 540mA).

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The Bridgelux BXEB-L0280Z-35E1000-C-B3 is a direct functional substitute for the Samsung SI-B8U07128HWW based on matching critical parameters: identical linear light strip configuration, color temperature (3500K), color rendering index (80), flat lens type, and comparable physical dimensions within mechanical tolerance.

Key Considerations:

1. Product Status: The Samsung part is marked "Not For New Designs," while the Bridgelux substitute is "Active." For new applications or long-term supply requirements, the Bridgelux part is the recommended selection.

2. Compliance: Both parts meet RoHS requirements (RoHS Compliant vs. ROHS3 Compliant). The Bridgelux part includes REACH Unaffected status, providing additional regulatory clarity.

3. Forward Voltage Difference: The substitute operates at 19.5V typical versus 23.4V for the original part. This 3.9V difference requires verification that the existing LED driver circuit can accommodate the lower voltage. Adjustable constant-current drivers typically support this range; fixed-voltage supplies may require modification.

4. Performance Enhancement: The substitute delivers 1195 lm versus 1090 lm (9.6% higher output) and 175 lm/W versus 155 lm/W (12.9% higher efficiency). These improvements are beneficial for light output and thermal management.

5. Mechanical Compatibility: Dimensional differences are negligible (≤0.3 mm across all axes), ensuring mechanical fit in existing fixtures.

6. Current Ratings: The substitute's maximum current rating (700mA) exceeds the original (540mA), providing additional thermal headroom and reliability margin.

Selection Path:

For direct replacement in existing systems: Verify driver compatibility with 19.5V forward voltage before substitution.

For new designs: Select the Bridgelux BXEB-L0280Z-35E1000-C-B3 as the primary component due to active product status and superior performance metrics.

Frequently Asked Questions (FAQ)

Q1: Can the Bridgelux BXEB-L0280Z-35E1000-C-B3 be used as a direct drop-in replacement for the Samsung SI-B8U07128HWW?

A: Mechanical and optical compatibility is confirmed. However, the forward voltage difference (19.5V vs. 23.4V) requires driver circuit verification. If the existing driver is a constant-current type with adequate voltage headroom, substitution is feasible. Fixed-voltage supplies may require adjustment or replacement.

Q2: What is the significance of the "Not For New Designs" status on the Samsung part?

A: This designation indicates the part has reached end-of-life in Samsung's product portfolio and is no longer recommended for new applications. Existing inventory may be available, but long-term supply cannot be guaranteed. The Bridgelux substitute, marked "Active," is the recommended choice for new designs and applications requiring sustained supply.

Q3: Are the physical dimensions compatible between these two modules?

A: Yes. The Samsung part measures 279.70 × 23.80 × 5.80 mm, while the Bridgelux part measures 280.00 × 24.00 × 6.10 mm. Differences are within 0.3 mm across all dimensions, ensuring mechanical compatibility in standard fixture designs.

Q4: How do the light output specifications compare?

A: The Bridgelux substitute produces 1195 lm at 350mA and 25°C, compared to 1090 lm for the Samsung part at 300mA and 50°C. Direct comparison is complicated by different test conditions; however, the Bridgelux part demonstrates superior efficiency (175 lm/W vs. 155 lm/W), indicating higher light output per watt of power consumed.

Q5: Are both parts compliant with environmental regulations?

A: Yes. The Samsung part is RoHS Compliant, and the Bridgelux part is ROHS3 Compliant. Both meet current environmental standards. The Bridgelux part additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.

Q6: What is the impact of the 5° difference in viewing angle (115° vs. 120°)?

A: The Bridgelux substitute has a slightly wider light distribution angle (120° vs. 115°). This results in marginally broader light spread, which is generally beneficial for general illumination applications. For applications requiring precise beam control, this minor difference should be evaluated in the specific optical design context.

Q7: Can the higher maximum current rating of the Bridgelux part (700mA vs. 540mA) be utilized?

A: The maximum current rating defines the thermal and reliability limits of the module. Operating at the original part's 300mA test current or up to 540mA maximum is safe with the Bridgelux substitute. Higher currents (up to 700mA) are permissible within the Bridgelux specification but should only be used if thermal management and system design accommodate the increased power dissipation.

Q8: What packaging differences exist, and do they affect compatibility?

A: The Samsung part is supplied in Tray packaging, while the Bridgelux substitute is supplied in Bulk packaging. Packaging affects handling, storage, and logistics but does not impact functional or mechanical compatibility of the modules themselves.

Q9: Are there any certifications or compliance documents required for substitution?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, simplifying export and tariff compliance. Verify that your application's specific regulatory requirements (industry standards, safety certifications, etc.) are met by both parts before final selection.

Q10: What should be verified before implementing this substitution in production?

A: Conduct driver circuit compatibility testing with the 19.5V forward voltage specification. Verify thermal performance under actual operating conditions. Confirm that the wider viewing angle (120° vs. 115°) meets optical design requirements. Validate that existing fixtures accommodate the minor dimensional differences. Perform photometric measurements to confirm color temperature and CRI consistency in the application context.
