SCS7VT93HPL2VLS03F LED Equivalent & Substitute Parts

Part Overview

The SCS7VT93HPL2VLS03F is a warm white LED (3000K) manufactured by Samsung Semiconductor, Inc., designed for surface mount applications in the 0505 (1313 Metric) package format. This component operates at 5.9V typical forward voltage with a 150mA test current, delivering 111lm at 85°C and 125 lm/W efficiency. The part is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCS7VT93HPL2VLS03F is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain warm white 3000K output with 5-Step MacAdam Ellipse specification to ensure color consistency in lighting applications.

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

RoHS Compliance and Moisture Sensitivity Level: All substitute parts must maintain RoHS compliance and MSL 2A rating to ensure regulatory conformance and handling compatibility.

Mounting Type and Surface Mount Compatibility: Substitutes must be surface mount components suitable for automated assembly processes.

Electrical Operating Parameters: Forward voltage, test current, maximum current, and luminous flux specifications determine functional equivalence. Substitutes may operate at different voltage and current levels if the overall electrical characteristics remain within acceptable design parameters for the target application.

Package Considerations: While the main part uses 0505 (1313 Metric) packaging, substitute parts may utilize different package sizes (such as 1111 or 2828 Metric) provided the application PCB layout can accommodate the physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The SCP7VTJ5HEL1VLPF6E is an active substitute for the obsolete SCS7VT93HPL2VLS03F. Both components are manufactured by Samsung Semiconductor, Inc., and share identical color temperature (3000K warm white), CRI (70), thermal resistance (2°C/W), RoHS compliance, and MSL rating (2A, 4 Weeks).

The substitute operates at significantly lower forward voltage (2.9V vs. 5.9V) and higher test current (700mA vs. 150mA), resulting in higher luminous flux output (320lm vs. 111lm) and superior luminous efficiency (158 lm/W vs. 125 lm/W). The substitute uses a larger 1111 (2828 Metric) package compared to the main part's 0505 (1313 Metric) package, with a slightly wider viewing angle reduction (120° vs. 145°).

Selection of the SCP7VTJ5HEL1VLPF6E requires circuit redesign to accommodate the different electrical operating point (lower voltage, higher current). PCB layout modifications are necessary to accommodate the larger package footprint. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SCP7VTJ5HEL1VLPF6E directly replace the SCS7VT93HPL2VLS03F without circuit modification?

A: No. The substitute operates at 2.9V typical forward voltage compared to the main part's 5.9V. Direct substitution requires redesign of the LED driver circuit and current-limiting resistor network to accommodate the different electrical operating point.

Q: What are the key compatibility criteria for these parts?

A: Both parts maintain identical warm white 3000K color temperature with 5-Step MacAdam Ellipse specification, CRI of 70, RoHS compliance, and MSL 2A rating. These parameters ensure color consistency and regulatory conformance.

Q: How does the package size difference affect PCB design?

A: The substitute uses a 1111 (2828 Metric) package measuring 2.80mm x 2.80mm, compared to the main part's 0505 (1313 Metric) package at 1.34mm x 1.34mm. PCB footprint, trace routing, and component placement must be redesigned to accommodate the larger package dimensions.

Q: Why is the substitute more efficient despite lower forward voltage?

A: The SCP7VTJ5HEL1VLPF6E achieves 158 lm/W efficiency at 700mA test current, compared to 125 lm/W for the main part at 150mA. Higher luminous flux output (320lm vs. 111lm) reflects improved LED die technology in the active LH231B series.

Q: Are there viewing angle implications for substitution?

A: The substitute provides a 120° viewing angle compared to the main part's 145°. Applications requiring wide-angle light distribution may require optical design adjustments or multiple LED placement to achieve equivalent coverage.

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

A: The main part is obsolete, indicating discontinued production and limited inventory availability. The substitute is active, ensuring ongoing manufacturing, consistent supply, and long-term design support.

Q: How do the maximum current ratings affect thermal management?

A: Both parts share identical 2°C/W thermal resistance. The substitute's 2A maximum current rating (vs. 250mA for the main part) requires careful thermal design to prevent junction temperature excursion during high-current operation.
