SI-B8U07228HWW LED Module - Equivalent & Substitute Parts

Part Overview

The SI-B8U07228HWW is a Samsung Semiconductor LED Module classified as LT-S282H, a warm white linear light strip with 3500K color temperature. This component is designated as "Not For New Designs," indicating it has reached end-of-life status in Samsung's product portfolio. The module delivers 1090 lumens at typical operating conditions and operates at 23.4V forward voltage with a maximum current rating of 540mA.

Finding equivalent substitute parts is necessary for applications currently using this module, as Samsung has discontinued active support and development for this series. Substitutes must maintain compatibility across critical electrical parameters, physical dimensions, and optical characteristics to ensure drop-in replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-B8U07228HWW is determined by strict alignment across the following parameters:

Critical Matching Parameters:

• Color Temperature: 3500K (3-Step MacAdam Ellipse tolerance)
• Configuration: Linear Light Strip form factor
• Lens Type: Flat optical interface
• Physical Dimensions: Length and width within tolerance of 279.70mm L x 23.80mm W
• Height: Vertical profile at 7.40mm
• CRI: Minimum 80 Color Rendering Index
• RoHS Compliance: Required for regulatory alignment

Electrical Compatibility Parameters:

• Forward Voltage (Vf): Operating range must accommodate 23.4V nominal
• Maximum Current: Must support at least 540mA rating
• Luminous Flux: Minimum 1090lm at specified test conditions

Acceptable Variance: Substitute parts may exhibit variations in test current (300mA baseline), test temperature conditions, and lumens-per-watt efficiency, provided all critical parameters remain within specified tolerances and the component maintains functional equivalence in the target application.

Engineering Selection Recommendations

Substitution Feasibility: BXEB-L0280Z-35E1000-C-B3 (Bridgelux)

The Bridgelux BXEB-L0280Z-35E1000-C-B3 qualifies as a functional equivalent for the Samsung SI-B8U07228HWW based on the following engineering criteria:

Compliance Alignment: Both components maintain RoHS compliance (Samsung RoHS Compliant; Bridgelux ROHS3 Compliant), ensuring regulatory compatibility in target markets. Both share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming trade and export compliance equivalence.

Optical and Thermal Characteristics: Color temperature specification (3500K, 3-Step MacAdam Ellipse) and Color Rendering Index (CRI 80) are identical, ensuring color consistency in lighting applications. Both employ flat lens optics and linear light strip configuration, maintaining optical interface compatibility.

Physical Compatibility: Dimensional variance is minimal: length difference of 0.30mm (280.00mm vs. 279.70mm) and width difference of 0.20mm (24.00mm vs. 23.80mm) fall within standard manufacturing tolerances for linear light strip modules. Height reduction from 7.40mm to 6.10mm provides improved clearance in space-constrained applications.

Electrical Considerations: The substitute operates at lower forward voltage (19.5V vs. 23.4V), reducing power supply stress and improving thermal efficiency. Maximum current rating increases from 540mA to 700mA, providing operational headroom. Luminous flux output increases from 1090lm to 1195lm at the substitute's test conditions, delivering enhanced brightness performance.

Product Status Advantage: The Bridgelux component maintains "Active" product status, ensuring continued availability, technical support, and supply chain stability compared to the Samsung part's "Not For New Designs" designation.

Frequently Asked Questions (FAQ)

Q: Can the BXEB-L0280Z-35E1000-C-B3 directly replace the SI-B8U07228HWW in existing applications?

A: Yes, the Bridgelux module qualifies as a direct substitute based on matching color temperature (3500K), configuration (linear light strip), optical characteristics (flat lens, 80 CRI), and physical dimensions within manufacturing tolerance. The lower forward voltage (19.5V vs. 23.4V) and reduced height (6.10mm vs. 7.40mm) are advantageous for most applications.

Q: What is the impact of the forward voltage difference (23.4V vs. 19.5V)?

A: The 3.9V reduction in forward voltage decreases power consumption and thermal generation at equivalent current levels. Existing power supplies rated for 23.4V will operate the substitute at reduced stress. Applications with current-limited supplies may experience slightly higher current draw due to lower impedance, but the substitute's 700mA maximum rating accommodates this variance.

Q: Are there dimensional concerns with the height reduction from 7.40mm to 6.10mm?

A: The 1.30mm height reduction provides additional clearance in space-constrained designs. Applications with tight vertical tolerances should verify that the lower profile does not affect optical alignment or thermal management. The reduced height does not compromise electrical or optical performance.

Q: How do the luminous flux specifications compare?

A: The Samsung module delivers 1090lm at 300mA test current and 50°C. The Bridgelux substitute delivers 1195lm at 350mA test current and 25°C. Direct comparison requires normalization to identical test conditions; however, the substitute demonstrates higher efficiency (175 lm/W vs. 155 lm/W), indicating improved light output per watt consumed.

Q: What packaging differences exist between these components?

A: The Samsung SI-B8U07228HWW ships in Tray packaging, while the Bridgelux BXEB-L0280Z-35E1000-C-B3 ships in Bulk packaging. Tray packaging provides individual component protection; bulk packaging reduces per-unit cost for high-volume applications. Verify packaging requirements for your supply chain and handling procedures.

Q: Are both components RoHS compliant?

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

Q: What is the viewing angle difference, and does it matter?

A: The Samsung module specifies 115° viewing angle; the Bridgelux substitute specifies 120°. The 5° increase provides slightly wider light distribution. For applications requiring specific beam geometry, verify that the wider angle aligns with optical design requirements.

Q: Can I use the substitute in new designs?

A: Yes. The Bridgelux BXEB-L0280Z-35E1000-C-B3 maintains "Active" product status, making it suitable for new designs. The Samsung SI-B8U07228HWW is designated "Not For New Designs," making the Bridgelux substitute the recommended choice for ongoing development.
