LED Module SI-B8T14156SWW Equivalent & Substitute Parts

Part Overview

The SI-B8T14156SWW is a Samsung Semiconductor LED Module classified as LT-S562F Linear Light Strip, designed for neutral white lighting applications at 4000K color temperature. This component is designated as Obsolete product status, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. The module delivers 2250 lumens at typical operating conditions with a forward voltage of 17.6V and operates at 800mA test current, providing 160 lumens per watt efficiency. Due to its obsolete classification, sourcing alternatives that maintain electrical and mechanical compatibility is critical for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-B8T14156SWW are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Color Temperature: 4000K neutral white (mandatory match)
• Color Rendering Index: 80 (mandatory match)
• Configuration: Linear Light Strip (mandatory match)
• Lens Type: Flat (mandatory match)
• Base Product Number: SI-B8 (same product family)

Secondary Compatibility Parameters:

• Luminous flux within acceptable operational range for the application
• Forward voltage compatible with existing power supply infrastructure
• Physical dimensions permitting mechanical integration
• RoHS compliance status maintained

The SI-B8T123560WW qualifies as a direct substitute based on matching all primary criteria. This part belongs to the V Gen3 series within the SI-B8 product family, maintaining the same color temperature, CRI, configuration, and lens specification while offering improved efficiency and updated component technology.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SI-B8T123560WW is a valid substitute for the obsolete SI-B8T14156SWW based on matching critical optical and electrical specifications. Both components share identical color temperature (4000K), color rendering index (80), configuration (Linear Light Strip), and lens type (Flat), ensuring functional equivalence for lighting output characteristics.

Key Considerations for Implementation:

1. Forward Voltage Differential: The substitute operates at 22.2V compared to the original 17.6V. This 26% increase requires verification that existing power supply infrastructure can accommodate the higher voltage requirement without modification.

2. Current Operating Point: The substitute operates at 530mA test current versus 800mA for the original. This lower current at higher voltage results in improved efficiency (186 lm/W versus 160 lm/W), reducing thermal load.

3. Mechanical Integration: The substitute features a narrower width (18.00mm versus 23.80mm) and lower profile (3.70mm versus 5.80mm). These dimensional reductions may improve thermal management and allow for more compact fixture designs, but mechanical mounting interfaces must be verified for compatibility.

4. Luminous Flux Consistency: Output difference of 50 lumens (2.2% variance) is within acceptable tolerance for most lighting applications and reflects improved efficiency rather than reduced capability.

5. Product Status: The substitute is Active production status, ensuring long-term availability and supply chain stability compared to the Obsolete original.

6. Regulatory Compliance: Both components maintain RoHS compliance and identical ECCN/HTSUS classifications, preserving regulatory and export compliance status.

Frequently Asked Questions (FAQ)

Q: Can SI-B8T123560WW directly replace SI-B8T14156SWW without any modifications?

A: Direct mechanical and optical replacement is feasible. However, the 26% higher forward voltage (22.2V vs. 17.6V) requires confirmation that the power supply circuit can deliver the required voltage. If the existing supply is voltage-regulated to 17.6V, circuit modification is necessary.

Q: What is the impact of the different test current specifications (530mA vs. 800mA)?

A: The substitute operates at a lower current while maintaining comparable luminous output. This reflects improved LED efficiency in the V Gen3 series. The maximum current rating is higher (1.8A vs. 1.44A), providing greater operational headroom. The application should be designed to operate at the substitute's specified test current for optimal performance.

Q: Are the physical dimension differences significant for mechanical integration?

A: The substitute is narrower (18.00mm vs. 23.80mm) and lower profile (3.70mm vs. 5.80mm). These reductions may require fixture redesign if the original dimensions were critical for mechanical fit. The length is essentially identical (560.00mm vs. 559.70mm). Verify mounting bracket and thermal interface compatibility.

Q: Does the substitute provide equivalent light output?

A: Yes. The luminous flux difference is 50 lumels (2.2% reduction from 2250lm to 2200lm), which is negligible for most applications. The substitute achieves this output at lower current, indicating superior efficiency (186 lm/W vs. 160 lm/W).

Q: Are color characteristics identical between the two parts?

A: Yes. Both components specify 4000K color temperature and CRI 80. The substitute's viewing angle is marginally wider (118° vs. 115°), providing slightly improved light distribution uniformity.

Q: What is the significance of the Obsolete vs. Active product status?

A: The original SI-B8T14156SWW is Obsolete, meaning Samsung has discontinued production and support. The substitute SI-B8T123560WW is Active production, ensuring availability, technical support, and supply chain continuity for future requirements.

Q: Are there any compliance or certification differences?

A: No. Both components share identical RoHS compliance status, ECCN (EAR99), and HTSUS classification (8541.41.0000), maintaining regulatory and export compliance equivalence.
