Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS9WT93HPL2WLS03F is determined by the following critical parameters:

Color and CCT Match: Both the main part and substitute must deliver white warm light at 2700K with 5-Step MacAdam Ellipse color consistency and CRI of 90 or higher.

Electrical Compatibility: Forward voltage, test current, and maximum current ratings must be evaluated against the application circuit design. The substitute SCP9WTJ5HEL1WLHF6E operates at 2.9V with 700mA test current, representing a different electrical operating point.

Optical Performance: Lumens output and lumens-per-watt efficiency are application-dependent metrics. The substitute delivers higher absolute flux (220lm at 85°C) but operates at different current levels.

Viewing Angle: The main part provides 145° viewing angle; the substitute provides 120°, affecting light distribution characteristics.

Package and Mounting: The main part uses 0505 (1313 Metric) package; the substitute uses 1111 (2828 Metric) package. These are physically distinct form factors requiring PCB layout redesign.

Product Status and Compliance: The main part is obsolete; the substitute is active production. Both are RoHS compliant with identical MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The SCP9WTJ5HEL1WLHF6E can serve as a functional substitute for the obsolete SCS9WT93HPL2WLS03F based on matched color temperature (2700K), color rendering index (CRI 90), and compliance certifications (RoHS, MSL 2A). Both devices are manufactured by Samsung Semiconductor, Inc., and maintain identical thermal resistance characteristics.

Circuit-Level Modifications Required: Direct pin-for-pin substitution is not possible. The substitute operates at 2.9V forward voltage compared to the main part's 5.9V, requiring power supply circuit redesign. The test current increases from 150mA to 700mA, necessitating current-limiting resistor or driver circuit adjustment. Maximum current rating increases to 2A, allowing higher operational headroom.

Physical Layout Redesign: The package transition from 0505 (1313 Metric) to 1111 (2828 Metric) requires PCB footprint modification. The substitute is approximately twice the linear dimension, affecting board space allocation and thermal management layout.

Optical Performance Trade-offs: The substitute delivers 220 lumens at 85°C versus 87 lumens for the main part, representing a 2.5x increase in luminous flux. However, the viewing angle narrows from 145° to 120°, affecting light distribution in wide-angle applications.

Production Continuity: The substitute is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the SCP9WTJ5HEL1WLHF6E be used as a direct replacement without circuit modifications?

A: No. The substitute requires circuit redesign due to different forward voltage (2.9V vs. 5.9V) and test current (700mA vs. 150mA). Power supply and current-limiting components must be recalculated for the new operating point.

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

A: Yes. Both devices deliver warm white light at 2700K with 5-Step MacAdam Ellipse color consistency and CRI of 90, ensuring color matching in applications requiring consistent warm white output.

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

A: The substitute uses a 1111 (2828 Metric) package compared to the main part's 0505 (1313 Metric) package. This requires PCB footprint redesign, affects component density, and may impact thermal management due to the larger form factor.

Q: Does the substitute provide better efficiency?

A: Yes. The substitute achieves 108 lm/W compared to 98 lm/W for the main part, representing approximately 10% higher luminous efficacy at its specified test current of 700mA.

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

A: The main part provides 145° viewing angle for wide-angle light distribution; the substitute provides 120° for more focused beam characteristics. Application requirements determine which viewing angle is appropriate.

Q: Are both parts RoHS compliant and suitable for regulated environments?

A: Yes. Both the SCS9WT93HPL2WLS03F and SCP9WTJ5HEL1WLHF6E are RoHS compliant with MSL 2A (4 Weeks) moisture sensitivity rating, meeting regulatory requirements for controlled manufacturing environments.

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

A: The main part is obsolete, indicating discontinued production and potential supply constraints. The substitute is in active production, ensuring availability for new designs and ongoing production requirements.

Q: Can the higher maximum current rating of the substitute (2A vs. 250mA) be utilized?

A: The substitute's 2A maximum current rating provides operational headroom beyond the 700mA test current specification. Operating point selection depends on application requirements for brightness, efficiency, and thermal management.
