LED Module SI-B8U07128SWW Equivalent & Substitute Parts

Part Overview

The SI-B8U07128SWW is a Samsung Semiconductor LED Module classified as LT-S282F, a warm white linear light strip with 3500K color temperature. 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. Identification of equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design transitions to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8U07128SWW LED module is determined by alignment of the following critical parameters:

Color and CCT Matching: Both the main part and substitute must operate at 3500K warm white color temperature with 3-Step MacAdam Ellipse tolerance and maintain CRI of 80 or higher.

Configuration and Form Factor: The substitute must be a linear light strip configuration with flat lens type. Physical dimensions must be compatible with the application envelope (approximately 280mm length, 24mm width, 6mm height tolerance).

Electrical Characteristics: Forward voltage (Vf), maximum current rating, and luminous flux output must be within acceptable ranges for the target application. Test conditions (current and temperature) establish baseline performance metrics.

Compliance and Certifications: RoHS compliance status and MSL rating must meet or exceed the original part specifications to ensure manufacturing and storage compatibility.

Product Status: Active product status in the substitute ensures ongoing availability and technical support.

Parameter Comparison

Engineering Selection Recommendations

The BXEB-L0280Z-35E1000-C-B3 (Bridgelux EB Series™ Gen 2) qualifies as a functional substitute for the SI-B8U07128SWW based on matching color temperature (3500K), CRI (80), configuration (linear light strip), and physical form factor compatibility.

Active Product Status: The Bridgelux substitute carries Active product status, ensuring continued availability and technical support, whereas the Samsung part is designated Not For New Designs.

Compliance Alignment: Both parts maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting manufacturing and storage requirements.

Critical Design Consideration: The forward voltage differs substantially (8.8V vs. 19.5V). This electrical parameter difference necessitates circuit redesign in the power supply and current-limiting driver stage. The substitute operates at lower maximum current (0.70A vs. 1.44A), which may reduce thermal management requirements but requires validation against application power budgets.

Efficiency Advantage: The substitute demonstrates higher luminous efficacy (175 lm/W vs. 155 lm/W) under its test conditions, indicating improved energy efficiency.

Mechanical Compatibility: Physical dimensions are equivalent (280mm length, 24mm width, 6.1mm height vs. 279.7mm, 23.8mm, 5.8mm). The 0.3mm height difference requires verification of mechanical clearance in the target assembly.

Frequently Asked Questions (FAQ)

Q: Can the BXEB-L0280Z-35E1000-C-B3 be used as a direct drop-in replacement for the SI-B8U07128SWW?

A: No. While both parts share identical color temperature (3500K), CRI (80), and linear strip configuration, the forward voltage differs significantly (19.5V vs. 8.8V). This requires modification of the power supply and driver circuit. Direct substitution without electrical redesign will result in component failure or inadequate light output.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Color temperature and MacAdam Ellipse tolerance (3500K 3-Step), (2) CRI rating (80 minimum), (3) Configuration type (linear light strip), (4) Lens type (flat), (5) Physical dimensions (approximately 280mm × 24mm × 6mm), (6) RoHS and MSL compliance status, and (7) Product availability status.

Q: How do the test conditions affect the luminous flux comparison?

A: The SI-B8U07128SWW is tested at 800mA and 50°C, producing 1090 lm. The BXEB-L0280Z-35E1000-C-B3 is tested at 350mA and 25°C, producing 1195 lm. These different test conditions (current and temperature) make direct flux comparison invalid. The substitute's higher lumens/watt efficiency (175 vs. 155 lm/W) indicates superior energy conversion under its test conditions.

Q: What is the significance of the different packaging formats (Tray vs. Bulk)?

A: Packaging format affects handling, storage, and inventory management but does not impact electrical or optical performance. Tray packaging typically provides individual component protection, while Bulk packaging is more economical for high-volume applications. Verify that your assembly process and storage facilities are compatible with the substitute's Bulk packaging format.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are RoHS compliant and carry MSL Level 1 (Unlimited) rating. The substitute specifies ROHS3 compliance, which represents the current RoHS standard revision. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications for export and tariff purposes.

Q: What mechanical verification is required before substitution?

A: Verify that the 0.3mm height difference (5.8mm vs. 6.1mm) does not violate mechanical clearance constraints in your assembly. Confirm that the connector interface (if present) is compatible. Validate that the slightly wider viewing angle (120° vs. 115°) meets or exceeds optical distribution requirements.

Q: Why is the Samsung part marked "Not For New Designs"?

A: This designation indicates that Samsung has discontinued active development and support for the LT-S282F series. Existing inventory may remain available, but the manufacturer does not recommend this part for new product development. The Bridgelux substitute provides an active, supported alternative for ongoing production requirements.
