Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCP8RT78HPL1RLS06E is determined by the following critical parameters:

Color and Chromaticity: Both the main part and substitute must maintain cool white 5000K color temperature with 5-Step MacAdam Ellipse specification to ensure consistent color output in lighting applications.

Electrical Characteristics: Forward voltage, test current, and maximum current ratings must be compatible with existing circuit designs. Lumens per watt efficiency and flux output determine brightness performance.

Color Rendering Index (CRI): A CRI of 80 is maintained across substitute parts to preserve color accuracy requirements.

Compliance and Certifications: RoHS compliance and MSL rating (2A, 4 Weeks) must be matched to ensure regulatory conformance and moisture handling requirements.

Manufacturer Consistency: Samsung Semiconductor, Inc. maintains the substitute relationship within its product portfolio.

The substitute part SCP8RT78HEL1RLS06E shares the same base product number (SCP8RT78), manufacturer, color specification, CRI, compliance certifications, and thermal characteristics. However, it represents a different series (LM101B) with distinct electrical and optical parameters optimized for alternative application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCP8RT78HPL1RLS06E is obsolete, while the substitute SCP8RT78HEL1RLS06E is active. Selection of the active substitute ensures long-term supply availability and ongoing manufacturer support.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring regulatory conformance and moisture handling procedures remain consistent.

Electrical Parameter Differences: The substitute operates at lower test current (65mA versus 150mA) and lower forward voltage (2.8V versus 2.9V). Circuit designs must accommodate these electrical differences through appropriate current-limiting resistor adjustments and power supply specifications.

Optical Performance Trade-offs: The substitute delivers higher lumens per watt efficiency (192 lm/W versus 140 lm/W) but operates at reduced absolute flux output (35lm at 25°C versus 61lm at 85°C). Viewing angle is narrower (120° versus 150°), affecting light distribution characteristics.

Package and Form Factor Changes: The substitute uses a larger 0606 (1616 Metric) package compared to the 0505 (1313 Metric) main part. PCB layout modifications are required to accommodate the increased footprint dimensions.

Thermal Characteristics: Identical thermal resistance (2°C/W) between parts supports equivalent thermal management in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the SCP8RT78HEL1RLS06E directly replace the SCP8RT78HPL1RLS06E without circuit modifications?

A: No. While both parts share the same color temperature (5000K), CRI (80), and thermal characteristics, the substitute requires circuit modifications. The lower test current (65mA versus 150mA) and forward voltage (2.8V versus 2.9V) necessitate recalculation of current-limiting resistor values. Additionally, the larger package footprint (0606 versus 0505) requires PCB layout changes.

Q: What are the implications of the package size difference?

A: The substitute SCP8RT78HEL1RLS06E uses a 0606 (1616 Metric) package, which is larger than the main part's 0505 (1313 Metric) package. Dimensions increase from 1.18mm x 1.18mm to 1.70mm x 1.70mm. This requires PCB redesign to accommodate the larger footprint and may affect component density in space-constrained applications.

Q: How does the viewing angle difference affect application suitability?

A: The main part provides a 150° viewing angle, while the substitute provides 120°. The narrower viewing angle of the substitute concentrates light output over a smaller area, affecting light distribution patterns. Applications requiring wide-angle illumination may require design adjustments or alternative component selection.

Q: Are the color specifications identical between the main part and substitute?

A: Yes. Both parts maintain cool white 5000K color temperature with 5-Step MacAdam Ellipse specification and CRI of 80. Color output characteristics are equivalent for lighting applications requiring consistent chromaticity.

Q: What is the significance of the product status difference?

A: The main part (SCP8RT78HPL1RLS06E) is obsolete, indicating Samsung Semiconductor has discontinued production. The substitute (SCP8RT78HEL1RLS06E) is active, meaning it remains in production with ongoing manufacturer support, ensuring future availability and supply chain continuity.

Q: How do the flux output specifications compare?

A: The main part specifies 61 lumens at 85°C test conditions (55lm ~ 67lm range). The substitute specifies 35 lumens at 25°C test conditions (33lm ~ 37lm range). These measurements are taken at different temperatures and test currents, making direct comparison complex. Circuit designs must account for the lower absolute flux output of the substitute.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL rating 2A (4 Weeks), indicating identical moisture sensitivity levels and storage/handling requirements. Standard moisture control procedures for 2A-rated components apply to both parts.

Q: What compliance certifications apply to both parts?

A: Both the main part and substitute are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory conformance for both domestic and international applications.
