Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-B8R06128CWW is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer Base Series: Both parts must belong to the SI-B8 base product family to ensure compatibility with existing connector interfaces and thermal management infrastructure
• Configuration: Linear light strip form factor is required to maintain mechanical fit within the host system
• Color Temperature (CCT): 5000K cool white specification must be preserved to maintain consistent optical output and color consistency in the application
• Color Rendering Index (CRI): Minimum CRI of 80 ensures equivalent color quality performance
• Lens Type: Flat lens configuration maintains optical distribution characteristics
• RoHS Compliance: All substitute parts must maintain RoHS compliance status for regulatory alignment

Electrical Compatibility Considerations: Substitute parts may operate at different forward voltages and currents than the original part. System power supply and driver circuitry must be evaluated for compatibility with the substitute part's electrical specifications. The SI-B8R123560WW operates at 22.2V forward voltage and 530mA test current, requiring verification that the host system power delivery architecture can accommodate these parameters.

Mechanical Fit Verification: While both parts maintain the 18.00mm width and flat lens type, dimensional differences exist in length (275mm vs. 560mm) and height (5.50mm vs. 3.70mm). Physical integration into the host system must be confirmed before substitution.

Performance Envelope: The substitute part SI-B8R123560WW delivers significantly higher luminous flux (2200lm vs. 769lm) and improved efficiency (186 lm/W vs. 136 lm/W). System thermal management and optical design must accommodate these performance differences.

Engineering Selection Recommendations

Primary Substitution Path:

The SI-B8R123560WW is the designated substitute for the obsolete SI-B8R06128CWW based on the following engineering criteria:

1. Product Status Alignment: The SI-B8R123560WW maintains Active product status with confirmed inventory availability (1028 pcs), ensuring long-term supply chain continuity compared to the Obsolete status of the original part.

2. Regulatory Compliance: Both parts maintain identical RoHS compliance status and export classification (EAR99), ensuring no regulatory barriers to substitution.

3. Base Series Continuity: Both parts belong to the SI-B8 base product family, confirming connector interface and thermal management infrastructure compatibility.

4. Optical Specification Preservation: Identical CCT (5000K), CRI (80), color designation (White, Cool), and lens type (Flat) ensure optical output characteristics remain consistent with the original design intent.

5. Electrical System Verification Required: The substitute part operates at 22.2V forward voltage (vs. 12.6V) and 530mA test current (vs. 450mA). The host system power supply and driver circuitry must be evaluated to confirm compatibility with these electrical parameters. If the original system was designed for 12.6V operation, a new power supply or driver module may be required.

6. Mechanical Integration Assessment: The substitute part is 2.04 times longer (560mm vs. 275mm) and 1.80mm lower in height (3.70mm vs. 5.50mm). Physical mounting, thermal interface, and optical alignment within the host system must be verified before implementation.

7. Performance Envelope Consideration: The substitute delivers 186% higher luminous flux (2200lm vs. 769lm) and 37% higher efficiency (186 lm/W vs. 136 lm/W). System thermal management, optical design, and power delivery architecture must be evaluated to accommodate these performance characteristics.

Substitution Feasibility Summary:

Optical and regulatory substitution is direct and straightforward. Electrical and mechanical integration requires system-level engineering review and validation before production implementation.

Frequently Asked Questions (FAQ)

Q1: Can the SI-B8R123560WW be used as a direct drop-in replacement for the SI-B8R06128CWW?

A: No. While both parts share the same base series (SI-B8), color temperature (5000K), and optical specifications, they differ significantly in electrical requirements and physical dimensions. The substitute operates at 22.2V (vs. 12.6V) and is 2.04 times longer. System power supply, driver circuitry, and mechanical mounting must be re-evaluated and potentially redesigned.

Q2: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) SI-B8 base series membership, (2) linear light strip configuration, (3) 5000K color temperature, (4) CRI of 80 or higher, (5) flat lens type, and (6) RoHS compliance. The SI-B8R123560WW meets all these criteria.

Q3: Will the substitute part produce the same light output as the original?

A: No. The SI-B8R123560WW produces 2200 lumens compared to 769 lumens from the SI-B8R06128CWW. This 186% increase in luminous flux will result in significantly brighter illumination. System optical design and thermal management must accommodate this higher output.

Q4: What electrical modifications are required to use the substitute part?

A: The substitute part requires 22.2V forward voltage compared to 12.6V for the original part. If the host system was designed for 12.6V operation, the power supply and/or driver circuitry must be upgraded to deliver 22.2V at up to 530mA (test current) or 1.8A (maximum current). Existing 12.6V power supplies cannot be used without modification.

Q5: Are there mechanical compatibility issues?

A: Yes. The substitute part is 560mm long (vs. 275mm) and 3.70mm tall (vs. 5.50mm). Physical mounting locations, thermal interface materials, and optical alignment must be re-evaluated. The reduced height may affect thermal contact with heat sinks or thermal interface materials.

Q6: Is the substitute part currently available?

A: Yes. The SI-B8R123560WW is in Active product status with 1028 pieces in stock, ensuring reliable supply chain availability compared to the Obsolete SI-B8R06128CWW.

Q7: Do both parts have the same connector interface?

A: Both parts belong to the SI-B8 base series, which indicates compatible connector infrastructure. However, the specific connector type and pin configuration should be verified in the detailed product datasheets before final integration.

Q8: What is the efficiency difference between the two parts?

A: The SI-B8R123560WW operates at 186 lm/W compared to 136 lm/W for the SI-B8R06128CWW, representing a 37% efficiency improvement. This higher efficiency reduces power consumption per lumen of light output.

Q9: Are there any packaging differences?

A: The original part is specified with "-" packaging notation, while the substitute is packaged in Tray format. This may affect handling, storage, and integration into automated assembly processes.

Q10: Can the substitute part be used in applications requiring the exact same dimensions as the original?

A: No. The significant dimensional differences (2.04x longer, 1.80mm lower) make the substitute unsuitable for applications with strict spatial constraints. Alternative parts or custom mechanical adaptation would be required.
