LED Module SI-B8U071280LD Equivalent & Substitute Parts

Part Overview

The SI-B8U071280LD is a warm white linear LED light strip module manufactured by Samsung Semiconductor, Inc. This LED module delivers 1090 lumens at typical operating conditions with a color temperature of 3500K and a Color Rendering Index (CRI) of 80. The module features a flat lens configuration and operates at a forward voltage of 35.2V with a maximum current rating of 360mA.

The SI-B8U071280LD carries a product status of "Not For New Designs," indicating that Samsung has discontinued this model for new applications. This status necessitates identification of equivalent substitute components that maintain functional compatibility while offering active product support and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-B8U071280LD are identified based on strict alignment with the following critical parameters:

Color Temperature & Color Quality: The substitute must operate at 3500K (warm white) with a CRI of 80 to maintain identical color characteristics in the application.

Configuration & Form Factor: The substitute must be a linear light strip configuration to ensure mechanical and optical compatibility with existing fixtures and assemblies.

Electrical Characteristics: The substitute must operate within compatible voltage and current ranges. Forward voltage must be within acceptable tolerance of the original 35.2V specification. Maximum current rating must support the application's power requirements.

Optical Output: Luminous flux output should be comparable to the original 1090 lumens specification to maintain consistent illumination levels.

Mechanical Dimensions: Physical dimensions must be compatible with the original 280.00mm × 24.00mm × 5.80mm footprint to ensure proper installation in existing mechanical assemblies.

Regulatory Compliance: The substitute must maintain RoHS compliance and equivalent certifications (ECCN, HTSUS codes).

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The SSB1-24F01-3580-00 qualifies as a functional substitute for the SI-B8U071280LD based on matching critical parameters: identical color temperature (3500K), identical CRI (80), identical configuration (linear light strip), identical lens type (flat), and identical regulatory compliance (RoHS, ECCN, HTSUS).

Product Status Advantage: The SSB1-24F01-3580-00 carries an "Active" product status, ensuring continued manufacturing support, availability, and technical documentation. This contrasts with the SI-B8U071280LD's "Not For New Designs" status, which indicates end-of-life for new applications.

Electrical Compatibility: The forward voltage difference of 0.8V (2.3% lower for the substitute) falls within acceptable tolerance for most LED driver circuits. The substitute's maximum current rating of 300mA is lower than the original 360mA specification; applications operating at or near the 360mA maximum must be evaluated to confirm the substitute's 300mA limit is sufficient.

Optical Performance: The substitute delivers 1140 lumens compared to the original 1090 lumens at identical test conditions (200mA, 50°C), representing a 4.6% increase in light output. This higher output is compatible with applications requiring the original specification and may provide improved efficiency (164 lm/W versus 155 lm/W).

Mechanical Considerations: Dimensional differences are minor: the substitute is 0.5mm shorter in length, 2.0mm narrower in width, and 0.2mm taller in height. These variations require verification against specific mechanical mounting constraints in the target application. The connector feature specified for the original part is not explicitly documented for the substitute; connector compatibility must be confirmed during integration.

Compliance & Certifications: Both parts maintain identical RoHS compliance and export classification (EAR99, HTSUS 8541.41.0000), ensuring regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SSB1-24F01-3580-00 directly replace the SI-B8U071280LD in existing assemblies?

A: Direct replacement is feasible for most applications. The substitute matches critical parameters including color temperature, CRI, configuration, and lens type. However, verify that the 300mA maximum current rating is sufficient for your application, and confirm mechanical fit given the dimensional variations (0.5mm length difference, 2.0mm width difference, 0.2mm height difference). Connector compatibility must be confirmed with the substitute manufacturer.

Q: What is the significance of the "Not For New Designs" status on the SI-B8U071280LD?

A: This status indicates that Samsung has discontinued this model for new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. The SSB1-24F01-3580-00's "Active" status ensures continued manufacturing and support for new designs.

Q: How do the electrical specifications compare?

A: The substitute operates at 34.4V forward voltage compared to the original 35.2V, a difference of 0.8V (2.3%). This is typically acceptable for LED driver circuits with adequate voltage headroom. The substitute's maximum current rating is 300mA versus the original 360mA; applications must operate within the substitute's 300mA limit.

Q: Is the higher luminous flux output of the substitute (1140 lm vs. 1090 lm) a concern?

A: The 4.6% increase in light output is generally compatible with applications designed for the original specification. If precise lumen matching is required, this difference must be evaluated against application requirements. The substitute's improved efficiency (164 lm/W versus 155 lm/W) may provide thermal benefits.

Q: Are there any regulatory or compliance differences?

A: Both parts maintain identical RoHS compliance and export classifications (EAR99, HTSUS 8541.41.0000). No regulatory barriers to substitution exist based on provided specifications.

Q: What should be verified before implementing the SSB1-24F01-3580-00 as a substitute?

A: Confirm the following: (1) Maximum current requirement does not exceed 300mA; (2) Mechanical dimensions are compatible with existing fixtures, particularly the 2.0mm width reduction; (3) Connector type and pinout match the original specification; (4) Viewing angle specification for the substitute (not provided in available data) is acceptable for the application; (5) Thermal management is adequate given the 0.2mm height increase.
