Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS8VT93HPL2VUS03F is determined by the following critical parameters:

Color and CCT Matching: Both the main part and substitute must maintain warm white color specification at 3000K to preserve intended lighting characteristics and color rendering consistency.

CRI Requirement: Color Rendering Index of 80 is maintained across both parts to ensure equivalent color fidelity in lighting applications.

Mounting and Package Compatibility: Surface mount technology is required for both components. However, the substitute part utilizes a different package size (1111 / 2828 Metric versus 0505 / 1313 Metric), which affects PCB layout and thermal management considerations.

Electrical Operating Parameters: The substitute part operates at different voltage and current specifications (2.9V forward voltage, 700mA test current) compared to the main part (5.9V, 150mA). These differences require circuit redesign and are not direct pin-compatible substitutes.

Compliance and Environmental Ratings: Both parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring equivalent environmental handling and regulatory compliance.

Product Status Consideration: The main part is obsolete; the substitute part is active, providing ongoing availability for new designs and production continuity.

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Mitigation: The SCS8VT93HPL2VUS03F is classified as obsolete. The SCP8VTJ5HEL1VUNF6E substitute part is active and maintained in production by Samsung Semiconductor, Inc., providing long-term supply continuity and component availability.

Compliance Alignment: Both parts maintain identical RoHS compliance status and MSL ratings (2A, 4 Weeks), ensuring equivalent environmental handling requirements and regulatory conformance for applications subject to RoHS directives.

Functional Equivalence Scope: Substitution is applicable only in applications where the following design modifications are acceptable:

Circuit redesign to accommodate 2.9V forward voltage and 700mA test current specifications, differing from the original 5.9V and 150mA parameters.

PCB layout modification to accommodate the larger 1111 (2828 Metric) package footprint, approximately 2.1 times larger than the original 0505 (1313 Metric) package.

Acceptance of narrower viewing angle (120° versus 145°) in optical design.

Performance Characteristics: The substitute part delivers higher luminous flux (300lm at 85°C versus 103lm) and superior luminous efficacy (148 lm/W versus 116 lm/W), enabling potential power consumption reduction in equivalent brightness applications.

Color Consistency: Both parts maintain 3000K warm white color temperature with CRI of 80. The substitute specifies 3-Step MacAdam Ellipse tolerance, providing enhanced color consistency control.

Thermal Management: Identical thermal resistance (2°C/W) and comparable seated heights ensure equivalent thermal performance characteristics in PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can the SCP8VTJ5HEL1VUNF6E be used as a direct pin-compatible replacement for the SCS8VT93HPL2VUS03F?

A: No. While both are surface mount warm white LEDs from Samsung Semiconductor, they are not pin-compatible. The substitute requires circuit redesign due to different forward voltage (2.9V versus 5.9V) and test current (700mA versus 150mA) specifications. Additionally, the package size differs (1111 versus 0505), requiring PCB layout modification.

Q: What are the key differences in optical performance between these two parts?

A: The substitute part (SCP8VTJ5HEL1VUNF6E) delivers significantly higher luminous flux at 300lm compared to 103lm for the main part, and exhibits superior luminous efficacy at 148 lm/W versus 116 lm/W. However, the substitute has a narrower viewing angle of 120° compared to 145°. Both maintain identical color temperature (3000K) and CRI (80).

Q: Are there any environmental handling differences between these parts?

A: No. Both parts maintain identical MSL ratings of 2A (4 Weeks) and RoHS compliance status, requiring equivalent moisture control and environmental handling procedures during storage and assembly.

Q: What is the significance of the package size difference?

A: The substitute part uses a 1111 (2828 Metric) package, approximately 2.1 times larger in footprint than the original 0505 (1313 Metric) package. This requires PCB layout redesign and may affect space-constrained applications. Seated heights are comparable (0.52mm versus 0.48mm), minimizing vertical clearance impact.

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

A: The SCS8VT93HPL2VUS03F (LM102A series) has reached end-of-life status and is no longer manufactured. The SCP8VTJ5HEL1VUNF6E (LH231B series) represents Samsung Semiconductor's current warm white LED offering with equivalent color and compliance characteristics, ensuring ongoing availability for new designs and production continuity.

Q: Can the higher current rating of the substitute part (2A maximum versus 250mA) be utilized in existing circuit designs?

A: The higher maximum current rating does not automatically enable higher operating current in existing designs. The substitute part is specified for 700mA test current, compared to 150mA for the main part. Any increase in operating current requires complete circuit redesign, power supply adjustment, and thermal analysis to ensure safe operation within the substitute part's specifications.

Q: Are the color rendering characteristics identical between these parts?

A: Both parts maintain CRI of 80 and 3000K color temperature. The substitute specifies 3-Step MacAdam Ellipse tolerance, which provides tighter color consistency control compared to the main part specification. This represents an enhancement in color uniformity rather than a deviation.
