Engineering Selection Recommendations

The SI-B8R342560WW is the qualified substitute for the obsolete SI-B8R341550WW based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with Samsung Semiconductor, ensuring continued availability and supply chain reliability for new designs and replacement applications.

Compliance Certification: Both parts maintain RoHS Compliant status, satisfying regulatory requirements for electronic component procurement in regulated industries.

Functional Equivalence: The substitute part preserves all critical optical and electrical parameters: identical color temperature (5000K), color rendering index (80), viewing angle (115°), and connector configuration. Test current remains at 1.35A with forward voltage variation of only 0.1V (24.8V vs. 24.7V), which is within typical system design tolerance.

Performance Enhancement: The SI-B8R342560WW delivers improved luminous flux (4820lm vs. 4650lm) and efficiency (144 lm/W vs. 139 lm/W) while operating at a lower test temperature (50°C vs. 60°C), indicating improved thermal performance.

Mechanical Considerations: The substitute part is 1.4mm shorter in height (3.80mm vs. 5.20mm) and 10mm longer in length (560mm vs. 550mm). These dimensional differences must be evaluated against specific mechanical mounting and thermal management requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can SI-B8R342560WW directly replace SI-B8R341550WW in existing applications?

A: The SI-B8R342560WW is functionally equivalent for optical and electrical performance. Mechanical fit must be verified due to height reduction (5.20mm to 3.80mm) and length increase (550mm to 560mm). Connector compatibility is maintained as both parts feature connectors.

Q: What are the key differences between these two LED modules?

A: The primary differences are product status (obsolete vs. active), luminous flux output (4650lm vs. 4820lm), efficiency (139 vs. 144 lm/W), maximum current rating (not specified vs. 1.62A), and physical dimensions. Color temperature, CRI, viewing angle, and connector configuration remain identical.

Q: Are there any electrical compatibility concerns when substituting?

A: Forward voltage differs by 0.1V (24.7V to 24.8V), which is negligible in typical LED driver circuits. Test current remains constant at 1.35A. The substitute part specifies a maximum current of 1.62A, providing additional operational headroom compared to the main part.

Q: What is the significance of the lower test temperature for the substitute part?

A: The substitute part operates at 50°C test temperature versus 60°C for the main part, indicating improved thermal management and potentially lower junction temperatures during operation. This suggests enhanced reliability and thermal stability.

Q: Does packaging differ between these parts?

A: The main part packaging is not specified, while the substitute part is supplied in Tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes, both SI-B8R341550WW and SI-B8R342560WW are RoHS Compliant, meeting environmental and regulatory standards for electronic component use.
