Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SI-B8T923B20WW is a direct substitute for the obsolete SI-B8T52156CUS based on maintained electrical and optical specifications. Both components share identical color temperature (4000K), CRI (80), lens type (Flat), and configuration (Linear Light Strip). Both are manufactured by Samsung Semiconductor, Inc., and classified under the same base product platform (SI-B8).

Compliance and Certification:

Both parts carry identical export control classification (ECCN: EAR99) and harmonized tariff codes (HTSUS: 8541.41.0000), ensuring regulatory equivalence for procurement and logistics purposes.

Electrical Compatibility Considerations:

The substitute part operates at a lower typical forward voltage (45V versus 48.8V) with higher test current (2.02A versus 1.12A). Existing driver circuits designed for the main part must be evaluated for compatibility with these electrical parameters. The substitute part's maximum current specification (2.02A) aligns with its test current, indicating a narrower operational envelope compared to the main part.

Optical Performance:

The substitute part delivers approximately double the luminous flux output (16000 lm versus 7816 lm) at improved efficiency (176 lm/W versus 143 lm/W). Applications requiring the original flux output may require circuit modifications or alternative component selection.

Physical Integration:

The substitute part features double the length (1120 mm versus 560 mm) with reduced height (3.70 mm versus 5.50 mm). Mechanical integration must account for these dimensional differences in fixture design and thermal management.

Product Status:

The substitute part maintains active product status, ensuring continued availability and supply chain support compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can SI-B8T923B20WW directly replace SI-B8T52156CUS without circuit modifications?

A: Both parts maintain identical color temperature (4000K), CRI (80), and configuration (Linear Light Strip). However, electrical parameters differ: forward voltage is 3.8V lower (45V vs. 48.8V) and test current is 0.9A higher (2.02A vs. 1.12A). Driver circuit compatibility must be verified before direct substitution.

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

A: The substitute part (SI-B8T923B20WW) represents a generational advancement within the SI-B8 platform. It delivers double the luminous flux (16000 lm vs. 7816 lm), improved efficiency (176 lm/W vs. 143 lm/W), and extended viewing angle (118° vs. unspecified). Physical dimensions differ significantly: the substitute is twice as long (1120 mm vs. 560 mm) but thinner (3.70 mm vs. 5.50 mm).

Q: Are both parts available in the same packaging format?

A: Yes, both SI-B8T52156CUS and SI-B8T923B20WW are supplied in Tray packaging. However, the substitute part's increased length (1120 mm) may affect tray configuration and handling procedures.

Q: What is the product status difference, and why does it matter?

A: SI-B8T52156CUS is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory. SI-B8T923B20WW maintains active product status, ensuring ongoing manufacturing support, availability, and compliance with current Samsung Semiconductor specifications.

Q: Can the substitute part be used in applications designed for the original part?

A: Substitution feasibility depends on application-specific requirements. Both parts share identical color temperature, CRI, and configuration. Applications requiring the original part's specific luminous flux output (7816 lm) or electrical characteristics (48.8V, 1.12A test current) may require alternative component selection or circuit redesign to accommodate the substitute part's higher output and different electrical parameters.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts carry identical export control classification (ECCN: EAR99) and harmonized tariff codes (HTSUS: 8541.41.0000), ensuring equivalent regulatory treatment for procurement, import, and export purposes.
