Substitute Part Grouping Explanation

Substitution of the SI-B8V52256CUS is determined by the following critical parameters:

Primary Substitution Criteria:

• Base Product Number: Both parts share the SI-B8 base platform, confirming mechanical and electrical compatibility within the Samsung V-Series LED module family
• Configuration: Linear light strip format maintained across both parts
• Color Temperature (CCT): Both operate at 3000K, ensuring identical color output
• CRI (Color Rendering Index): Both maintain CRI of 80, preserving color rendering performance
• Lens Type: Flat lens configuration consistent across both parts
• Test Temperature: Both tested at 65°C operating conditions

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): SI-B8V52256CUS operates at 46.5V typical; substitute operates at 45V typical. This 1.5V differential is within acceptable tolerance for LED module substitution within the same base platform
• Current Specifications: Substitute part operates at higher current (2.02A test vs. 1.12A test), indicating enhanced performance capability
• Luminous Flux: Substitute delivers 15140 lumens versus 8300 lumens, representing increased light output while maintaining color temperature and CRI specifications

The SI-B8V923B20WW represents an active-status upgrade within the V-Series platform (Gen3 versus Gen2), providing superior performance metrics while maintaining functional equivalence for 3000K linear light strip applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SI-B8V52256CUS carries an obsolete designation, indicating Samsung has discontinued active manufacturing and support. The SI-B8V923B20WW maintains active product status, ensuring ongoing availability, technical support, and supply chain continuity.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent regulatory and export compliance profiles. This alignment eliminates compliance barriers to substitution.

Performance Metrics: The substitute part SI-B8V923B20WW delivers enhanced performance within the same functional category:

• Increased luminous flux (15140 lm vs. 8300 lm) provides superior light output
• Improved lumens-per-watt efficiency (167 lm/W vs. 159 lm/W) indicates better energy conversion
• Maintained CRI of 80 preserves color rendering characteristics
• Identical 3000K color temperature ensures color output consistency

Mechanical Compatibility: Both parts maintain the SI-B8 base platform with flat lens configuration and identical width (39.80 mm). The substitute features a reduced height profile (3.70 mm vs. 5.50 mm) and extended length (1120 mm vs. 560 mm), requiring mechanical design verification for space constraints and mounting configurations.

Electrical Compatibility: Forward voltage differential of 1.5V (46.5V vs. 45V) falls within acceptable tolerance for LED module substitution. Current specifications differ significantly (1.12A vs. 2.02A test current), requiring power supply and thermal management assessment for the higher-current substitute.

Frequently Asked Questions (FAQ)

Q: Can the SI-B8V923B20WW directly replace the SI-B8V52256CUS in existing designs?

A: Direct replacement requires mechanical and electrical design verification. The substitute maintains identical width and color temperature but features reduced height (3.70 mm vs. 5.50 mm), extended length (1120 mm vs. 560 mm), and higher operating current (2.02A vs. 1.12A). Power supply and thermal management systems must accommodate these differences.

Q: What is the significance of the obsolete status for the SI-B8V52256CUS?

A: Obsolete status indicates Samsung has discontinued manufacturing and active support. Existing inventory may become depleted, and technical support resources may become unavailable. The SI-B8V923B20WW active status ensures ongoing supply availability and manufacturer support.

Q: Are the color specifications identical between these parts?

A: Both parts operate at 3000K color temperature with CRI of 80. The SI-B8V52256CUS is designated as "White, Cool" while the SI-B8V923B20WW is designated as "White, Warm." Both maintain the same CCT value and CRI, ensuring equivalent color output for 3000K applications.

Q: What packaging differences exist between these parts?

A: The SI-B8V52256CUS ships in bulk packaging, while the SI-B8V923B20WW ships in tray packaging. This difference affects handling, storage, and component management procedures but does not impact functional performance.

Q: How do the luminous flux specifications compare?

A: The SI-B8V923B20WW delivers 15140 lumens compared to 8300 lumens for the SI-B8V52256CUS, representing an 82% increase in light output. This enhanced performance occurs at higher operating current (2.02A vs. 1.12A) and maintains improved efficiency (167 lm/W vs. 159 lm/W).

Q: Are there moisture sensitivity differences between these parts?

A: The SI-B8V52256CUS specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The SI-B8V923B20WW specifies MSL as Not Applicable, indicating the Gen3 design eliminates moisture sensitivity considerations. Both parts accommodate standard handling and storage procedures.

Q: What electrical design changes are required for substitution?

A: The substitute operates at 2.02A test current versus 1.12A for the original part, requiring power supply capacity assessment. Forward voltage is slightly lower (45V vs. 46.5V), which is within acceptable tolerance. Thermal management systems must accommodate the higher current and resulting increased power dissipation.
