Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7PT93HPL2PLS03F is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain cool white 6500K specification with 5-Step MacAdam Ellipse tolerance to ensure color consistency in lighting applications.

CRI (Color Rendering Index): A minimum CRI of 70 is required for acceptable color rendering performance.

Mounting Type and Surface Mount Compatibility: The substitute must be a surface mount LED suitable for automated assembly processes.

RoHS Compliance: All substitute parts must maintain RoHS compliance status for regulatory adherence.

Electrical Operating Parameters: Forward voltage, test current, and maximum current ratings determine circuit compatibility and thermal management requirements.

The substitute part SCP7PTJ5HEL1PLPF6E meets these core substitution criteria while operating in a different package size (1111 / 2828 Metric) with different electrical characteristics. This substitution is valid only when the application circuit and PCB layout can accommodate the larger package dimensions and different voltage/current specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCS7PT93HPL2PLS03F is classified as obsolete. The substitute part SCP7PTJ5HEL1PLPF6E carries an active product status, ensuring continued availability and manufacturing support from Samsung Semiconductor, Inc.

Compliance and Certification: Both parts maintain RoHS compliance and identical thermal resistance characteristics (2°C/W), supporting equivalent thermal management in circuit design.

Electrical Redesign Requirement: Substitution of SCP7PTJ5HEL1PLPF6E requires circuit redesign due to significant differences in forward voltage (5.9V vs. 2.9V) and test current (150mA vs. 700mA). Current-limiting resistor values and power supply specifications must be recalculated for the substitute part.

Package Footprint Change: The substitute operates in a larger 1111 (2828 Metric) package compared to the 0505 (1313 Metric) main part. PCB layout modifications are necessary to accommodate the increased component dimensions.

Optical Performance Variance: The substitute delivers higher luminous flux (320lm vs. 119lm) and improved efficiency (158 lm/W vs. 134 lm/W) but with a narrower viewing angle (120° vs. 145°). Application requirements determine acceptability of these optical trade-offs.

Frequently Asked Questions (FAQ)

Q: Can SCP7PTJ5HEL1PLPF6E be used as a direct drop-in replacement for SCS7PT93HPL2PLS03F?

A: No. While both parts share identical color temperature (6500K) and CRI (70) specifications, the substitute requires circuit redesign due to different forward voltage (2.9V vs. 5.9V) and test current (700mA vs. 150mA) ratings. Additionally, the larger package footprint (1111 vs. 0505) necessitates PCB layout modifications.

Q: What are the key parameters that determine LED substitution compatibility?

A: Substitution compatibility is determined by: color and CCT specification, CRI rating, forward voltage and current characteristics, package type and dimensions, mounting method, and regulatory compliance status (RoHS). Changes in any of these parameters require application-level evaluation.

Q: Why is the substitute part listed as active while the main part is obsolete?

A: Product status reflects current manufacturing availability. The SCP7PTJ5HEL1PLPF6E (LH231B series) represents Samsung's current-generation cool white LED offering, while the SCS7PT93HPL2PLS03F (LM102A series) has been discontinued. Active status ensures ongoing supply and technical support.

Q: How do the viewing angles differ between these parts?

A: The main part provides a 145° viewing angle, while the substitute offers 120°. This 25° reduction in viewing angle affects light distribution characteristics and may impact applications requiring wide-angle illumination.

Q: What circuit modifications are necessary for substitution?

A: The substitute's lower forward voltage (2.9V vs. 5.9V) and higher test current (700mA vs. 150mA) require recalculation of current-limiting resistor values and verification of power supply capacity. Thermal management design must account for the higher current draw.

Q: Are both parts RoHS compliant?

A: Yes. Both SCS7PT93HPL2PLS03F and SCP7PTJ5HEL1PLPF6E maintain RoHS compliance status, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the 5-Step MacAdam Ellipse specification?

A: The 5-Step MacAdam Ellipse defines the color tolerance range for the 6500K cool white specification. Both parts maintain this tolerance, ensuring consistent color output within acceptable limits for lighting applications.
