Substitute Part Grouping Explanation

Substitute parts for the SI-B8R341B2CUS are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Base Product Number: SI-B8 (common platform)
• Color: White, Cool
• CCT (K): 5000K (color temperature match)
• Configuration: Linear Light Strip
• Physical Dimensions: 1120.00mm L x 18.00mm W (form factor compatibility)
• Lens Type: Flat
• CRI (Color Rendering Index): 80 (color accuracy requirement)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): Range 44.4V to 48V (acceptable operating voltage window)
• Current - Test: 530mA to 700mA (operational current range)
• Lumens/Watt: 146 to 187 lm/W (efficiency variation acceptable)
• Viewing Angle: 118° to 120° (optical performance tolerance)

The identified substitutes maintain the same base platform (SI-B8), color specification, color temperature, and physical footprint while operating within compatible electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

SI-B8R342B2CUS (V-Series Gen2)

This substitute maintains identical test current (700mA) and physical height (5.50mm) as the main part. Forward voltage is 1.6V lower (46.4V vs. 48V), and luminous flux output is 15.6% higher (5690 lm vs. 4920 lm). Maximum current rating is reduced to 900mA. Product status is obsolete, matching the main part classification. This substitute is suitable for applications where higher luminous output and lower forward voltage are acceptable within the design envelope.

SI-B8R243B20WW (V Gen3)

This substitute represents the active product generation within the SI-B8 platform. Forward voltage is 3.6V lower (44.4V vs. 48V), and efficiency is significantly higher at 187 lm/W compared to 146 lm/W. Luminous flux is 10.5% lower (4400 lm vs. 4920 lm) at reduced test current (530mA vs. 700mA). Physical height is reduced to 3.70mm, and maximum current rating is increased to 1.8A. Packaging is tray format rather than bulk. This substitute is the recommended choice for new designs requiring active product status and improved efficiency characteristics.

Frequently Asked Questions (FAQ)

Q: Can SI-B8R243B20WW directly replace SI-B8R341B2CUS in existing designs?

A: SI-B8R243B20WW maintains the same base platform (SI-B8), color temperature (5000K), physical length and width (1120mm x 18mm), and CRI (80). However, the reduced height (3.70mm vs. 5.50mm) and lower forward voltage (44.4V vs. 48V) require verification of mechanical fit and power supply compatibility. The reduced luminous flux (4400 lm vs. 4920 lm) at lower test current (530mA vs. 700mA) may affect brightness output depending on application requirements.

Q: What are the key differences between SI-B8R342B2CUS and SI-B8R243B20WW?

A: SI-B8R342B2CUS maintains the original height (5.50mm) and test current (700mA) with higher luminous output (5690 lm). SI-B8R243B20WW is the newer generation with reduced height (3.70mm), lower test current (530mA), and higher efficiency (187 lm/W vs. 175 lm/W). SI-B8R243B20WW has active product status, while SI-B8R342B2CUS is obsolete.

Q: Does packaging format affect electrical performance?

A: Packaging format (bulk vs. tray) does not affect electrical performance or functional characteristics. The difference is logistical, relating to quantity per container and handling requirements. SI-B8R341B2CUS is supplied in bulk packaging, while both substitutes are supplied in tray packaging.

Q: Are all three parts compliant with the same export classifications?

A: Yes. All three parts (SI-B8R341B2CUS, SI-B8R342B2CUS, and SI-B8R243B20WW) share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, indicating equivalent regulatory compliance.

Q: What is the impact of forward voltage differences on power supply design?

A: The main part operates at 48V typical forward voltage. SI-B8R342B2CUS operates at 46.4V (1.6V lower), and SI-B8R243B20WW operates at 44.4V (3.6V lower). Power supplies designed for 48V operation will function with lower voltage parts, but designs optimized for lower voltage operation may not provide sufficient voltage for the main part. Current supply capability must also be verified against maximum current ratings (1.08A, 900mA, and 1.8A respectively).

Q: Which substitute is recommended for new product development?

A: SI-B8R243B20WW is the recommended substitute for new designs. It carries active product status, indicating ongoing manufacturer support and availability. It also demonstrates improved efficiency (187 lm/W) and lower forward voltage requirements compared to the obsolete main part.
