Key Parameters

Substitute Part Grouping Explanation

Substitution of the Samsung LM362A is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must operate at cool white 6500K to maintain color consistency in lighting applications.

Luminous Flux and Efficacy: The substitute must deliver comparable light output at its specified test current. The LM362A produces 85 lumens at 100mA; substitute parts must provide equivalent or superior luminous performance within acceptable tolerance ranges.

Forward Voltage: Operating voltage must be compatible with existing driver circuits. The LM362A operates at 5.96V typical; substitutes operating at similar voltage levels minimize circuit redesign requirements.

Test Current and Maximum Current Ratings: Current specifications determine thermal management and circuit protection requirements. The LM362A is rated for 100mA test current and 200mA maximum current.

Color Rendering Index (CRI): A CRI of 80 is specified for the LM362A. Substitutes must maintain this or higher CRI to preserve color fidelity.

Mounting Type and Package Footprint: Surface mount compatibility and physical dimensions are critical for PCB integration. The LM362A uses a 2-SMD, No Lead package (3623) measuring 3.60mm × 2.30mm.

Regulatory Compliance: RoHS compliance status ensures environmental and regulatory alignment.

The Lumileds L130-6580003000W21 (LUXEON 3030 2D) meets these substitution criteria through matching color temperature, CRI, and surface mount configuration, while delivering superior luminous flux and thermal characteristics.

Engineering Selection Recommendations

Primary Substitute: Lumileds L130-6580003000W21 (LUXEON 3030 2D)

The Lumileds LUXEON 3030 2D is the qualified substitute for the obsolete Samsung LM362A based on the following engineering criteria:

Color Temperature Alignment: Both parts operate at 6500K cool white, ensuring color consistency in end-use applications.

CRI Equivalence: Both parts maintain a CRI of 80, preserving color rendering performance.

Luminous Performance: The LUXEON 3030 2D delivers 97 lumens at 120mA test current, exceeding the LM362A's 85 lumens at 100mA. This represents a 14% improvement in absolute flux output.

Regulatory Compliance: The LUXEON 3030 2D holds ROHS3 Compliant status, meeting current environmental regulations. The LM362A is RoHS Compliant, confirming both parts satisfy regulatory requirements.

Active Product Status: The LUXEON 3030 2D is classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete LM362A.

Thermal Performance: The LUXEON 3030 2D exhibits superior thermal characteristics with a thermal resistance of 12°C/W versus the LM362A's 15°C/W, enabling more efficient heat dissipation.

Circuit Integration Considerations: The forward voltage difference (6.1V versus 5.96V) represents a 0.14V increase. Driver circuits must be evaluated to confirm compatibility with this voltage shift. The test current increase from 100mA to 120mA requires verification that power supply and current-limiting components can accommodate the higher operating point.

Mechanical Footprint: The LUXEON 3030 2D uses a 1212 (3030 Metric) package measuring 3.00mm × 3.00mm, compared to the LM362A's 3.60mm × 2.30mm 2-SMD package. PCB layout modifications are required to accommodate the different footprint geometry.

Frequently Asked Questions (FAQ)

Q: Can the Lumileds LUXEON 3030 2D directly replace the Samsung LM362A without circuit modifications?

A: Direct replacement requires evaluation of two parameters. The forward voltage increases from 5.96V to 6.1V, a 0.14V difference that may be accommodated by existing driver circuits depending on their design margin. The test current increases from 100mA to 120mA, requiring confirmation that power supply capacity and current-limiting components support this higher operating point. PCB layout modification is mandatory due to different package footprints.

Q: What is the impact of the package footprint difference on PCB design?

A: The LM362A uses a 2-SMD, No Lead package (3623) measuring 3.60mm × 2.30mm. The LUXEON 3030 2D uses a 1212 (3030 Metric) package measuring 3.00mm × 3.00mm. The substitute has a smaller length (3.00mm versus 3.60mm) but greater width (3.00mm versus 2.30mm). PCB land pattern, solder pad geometry, and component placement must be redesigned to accommodate the new package dimensions.

Q: Are there viewing angle differences between these parts?

A: The LM362A specifies a 120° viewing angle. The LUXEON 3030 2D does not provide a viewing angle specification in the available data. Applications requiring a specific viewing angle must be evaluated independently or confirmed with the manufacturer.

Q: How do the luminous efficacy values compare?

A: The LM362A delivers 143 lm/W at 100mA test current. The LUXEON 3030 2D delivers 133 lm/W at 120mA test current. The LM362A exhibits higher efficacy per watt; however, the LUXEON 3030 2D delivers greater absolute luminous flux (97 lumens versus 85 lumens), which may be advantageous for applications requiring higher light output.

Q: What are the moisture sensitivity level (MSL) differences?

A: The LM362A is rated MSL 2A (4 Weeks), indicating a 4-week floor life after moisture exposure. The LUXEON 3030 2D is rated MSL 3 (168 Hours), indicating a 7-day floor life. The LM362A provides extended handling time. Storage and handling procedures must be adjusted accordingly when transitioning to the LUXEON 3030 2D.

Q: Is the thermal resistance improvement significant?

A: The LUXEON 3030 2D thermal resistance is 12°C/W compared to the LM362A's 15°C/W, representing a 20% improvement. This enables more efficient heat transfer from the LED junction to the PCB, reducing junction temperature at equivalent power dissipation and potentially extending component lifetime.

Q: Are both parts RoHS compliant?

A: Yes. The LM362A is RoHS Compliant. The LUXEON 3030 2D is ROHS3 Compliant, meeting current and future environmental regulations.
