Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-B8V07128SWW is determined by the following critical parameters:

Primary Substitution Criteria:

• Color temperature: 3000K warm white
• Configuration: Linear Light Strip
• Lens type: Flat
• Viewing angle: 115°
• CRI: 80 or higher
• Mechanical compatibility: Length 279.70mm, width tolerance within ±0.30mm, height tolerance within ±0.30mm

Electrical Operating Parameters:

• Forward voltage (Vf) range: 8.8V nominal (tolerance band determines compatibility)
• Maximum current rating: 1.44A or higher
• Test current: 800mA baseline
• Luminous flux: 1080 lm minimum at rated test conditions

Compliance Requirements:

• RoHS compliance (RoHS or ROHS3)
• MSL rating: 1 (Unlimited)

The substitute part SI-B8V06A28SEU meets the primary optical and mechanical criteria but operates at significantly different electrical parameters, requiring circuit design evaluation.

Engineering Selection Recommendations

SI-B8V06A28SEU as Primary Substitute:

The SI-B8V06A28SEU is classified as the manufacturer-recommended substitute and maintains active product status, ensuring long-term availability and supply chain continuity. Both components share identical optical specifications (3000K CCT, 80 CRI, 115° viewing angle) and mechanical form factor (279.70mm length, flat lens).

Critical Design Considerations:

The substitute part operates at 22.7V forward voltage compared to the original 8.8V, representing a 2.58× increase. Test current is reduced from 800mA to 280mA, with maximum current limited to 480mA versus 1.44A. These electrical differences require complete circuit redesign, including power supply reconfiguration and current limiting modifications. The substitute achieves superior efficiency at 171 lm/W versus 153 lm/W.

Compliance Status:

Both components satisfy RoHS requirements. The substitute carries ROHS3 certification, providing enhanced regulatory compliance for current and future applications. MSL rating remains at Level 1 (Unlimited) for both variants.

Mechanical Compatibility:

Width dimension differs by 0.30mm (23.80mm versus 23.50mm), and height differs by 0.30mm (5.80mm versus 5.50mm). These variations fall within standard manufacturing tolerances for linear light strip modules and do not preclude mechanical substitution in standard mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can SI-B8V06A28SEU be directly substituted for SI-B8V07128SWW without circuit modification?

A: No. The substitute operates at 22.7V forward voltage versus 8.8V, requiring complete power supply and current limiting circuit redesign. Direct pin-for-pin substitution is not possible.

Q: Are the optical outputs equivalent?

A: Optical specifications are equivalent. Both deliver 3000K warm white illumination with 80 CRI and 115° viewing angle. Luminous flux is comparable (1080 lm versus 1085 lm), though measured at different test currents.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute's Active status ensures manufacturer support, continued production, and supply availability. The original SI-B8V07128SWW is no longer manufactured, making the substitute the only viable long-term sourcing option.

Q: Do the mechanical dimensions differ significantly?

A: Dimensions differ by 0.30mm in width and height. These variations are within standard manufacturing tolerances for LED modules and do not affect standard mounting applications.

Q: Which component offers better energy efficiency?

A: The SI-B8V06A28SEU delivers 171 lm/W versus 153 lm/W for the original, representing an 11.8% efficiency improvement at its rated test current.

Q: Are both components RoHS compliant?

A: Yes. SI-B8V07128SWW carries RoHS compliance; SI-B8V06A28SEU carries ROHS3 compliance, which represents enhanced regulatory alignment.

Q: What is the maximum current rating difference?

A: SI-B8V07128SWW supports 1.44A maximum; SI-B8V06A28SEU supports 480mA maximum. This 3× reduction reflects the higher voltage architecture and requires corresponding circuit design changes.
