Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7UT93HPL2UUS03F is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Color Temperature (CCT): 3500K warm white specification
• Color: White, Warm
• Color Rendering Index (CRI): 70
• Mounting Type: Surface Mount
• Manufacturer: Samsung Semiconductor, Inc.
• RoHS Compliance: RoHS Compliant

Secondary Compatibility Factors:

• Luminous flux output range and efficiency
• Forward voltage and current operating characteristics
• Package form factor and thermal properties
• Product status and availability

The identified substitute part SCP7UTJ5HEL1UUPF6E maintains the same color temperature, color specification, and CRI rating. While this substitute operates at different electrical parameters (lower forward voltage, higher test current) and utilizes a larger package format (1111/2828 Metric versus 0505/1313 Metric), it satisfies the core functional requirement of warm white 3500K LED lighting with equivalent color rendering characteristics.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SCP7UTJ5HEL1UUPF6E is a valid substitute for the obsolete SCS7UT93HPL2UUS03F based on the following engineering factors:

1. Color Temperature Alignment: Both parts operate at 3500K warm white specification with CRI 70, ensuring identical color characteristics for lighting applications.

2. Product Status: The substitute part maintains Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

3. Compliance Certifications: Both parts are RoHS Compliant and manufactured by Samsung Semiconductor, Inc., maintaining regulatory and quality standards.

4. Thermal Properties: Identical thermal resistance of 2°C/W ensures equivalent thermal management performance in circuit designs.

Design Considerations for Substitution:

• Package Size Change: The substitute utilizes a larger 1111 (2828 Metric) package versus the 0505 (1313 Metric) main part. PCB layout modifications are required to accommodate the increased footprint (2.80mm × 2.80mm versus 1.34mm × 1.34mm).

• Electrical Parameter Differences: The substitute operates at 2.9V forward voltage and 700mA test current, compared to 5.9V and 150mA for the main part. Circuit power supply and current limiting designs must be adjusted accordingly.

• Luminous Output: The substitute delivers 320lm at 700mA test current versus 111lm at 150mA for the main part, representing significantly higher absolute light output. Application brightness requirements must be evaluated.

• Viewing Angle: The substitute provides 120° viewing angle versus 145° for the main part, affecting light distribution characteristics in directional lighting applications.

• Efficiency: The substitute achieves 158 lm/W versus 125 lm/W for the main part, indicating improved energy efficiency at its specified operating current.

Frequently Asked Questions (FAQ)

Q1: Can the SCP7UTJ5HEL1UUPF6E directly replace the SCS7UT93HPL2UUS03F without circuit modifications?

A: No. While both parts share the same color temperature (3500K) and CRI (70), the substitute requires circuit design changes. The forward voltage differs (2.9V versus 5.9V), and the test current is significantly higher (700mA versus 150mA). Power supply voltage, current limiting resistors, and driver circuits must be recalculated for the substitute part's electrical characteristics.

Q2: What are the key parameters that make these parts substitutable?

A: The substitution is based on matching color temperature (3500K), color (White, Warm), and color rendering index (70). Both parts are surface mount LEDs manufactured by Samsung Semiconductor, Inc., with RoHS compliance and identical thermal resistance (2°C/W). These parameters ensure equivalent color output and thermal performance in lighting applications.

Q3: Will the substitute part fit in the same PCB footprint as the main part?

A: No. The substitute uses a 1111 (2828 Metric) package measuring 2.80mm × 2.80mm, while the main part uses a 0505 (1313 Metric) package measuring 1.34mm × 1.34mm. PCB layout redesign is necessary to accommodate the larger footprint and pad spacing of the substitute part.

Q4: How do the luminous flux outputs compare between these parts?

A: The main part produces 111lm at 150mA test current, while the substitute produces 320lm at 700mA test current. The substitute delivers approximately 2.9 times higher absolute luminous flux. Application brightness requirements and optical design must be evaluated to determine if this increased output is acceptable or requires optical attenuation.

Q5: Are there differences in viewing angle between these parts?

A: Yes. The main part provides a 145° viewing angle, while the substitute provides a 120° viewing angle. This 25° difference affects light distribution characteristics. Applications requiring wide-angle light distribution may require optical design adjustments when substituting to the narrower viewing angle part.

Q6: What is the product status difference, and why does it matter?

A: The main part (SCS7UT93HPL2UUS03F) is classified as Obsolete, indicating discontinued production and limited availability. The substitute (SCP7UTJ5HEL1UUPF6E) is classified as Active, ensuring ongoing manufacturing and reliable long-term supply. For new designs or production continuity, the Active substitute part is preferred.

Q7: Are both parts RoHS compliant?

A: Yes. Both the SCS7UT93HPL2UUS03F and SCP7UTJ5HEL1UUPF6E are RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions in electronic components.

Q8: How do the efficiency ratings compare?

A: The main part achieves 125 lm/W at its 150mA test current, while the substitute achieves 158 lm/W at its 700mA test current. The substitute demonstrates higher luminous efficiency, producing more light output per watt of power consumed at its specified operating point.
