Substitute Part Grouping Explanation

Substitution of the Samsung LM362A (SPMWHT325AD5YBWMS0) is determined by the following critical parameters:

Color and CCT Matching: The substitute part must operate at warm white 2700K color temperature to maintain consistent color rendering in the application.

CRI Requirement: A CRI of 80 is required to ensure color rendering consistency.

Electrical Compatibility: The substitute must operate within acceptable forward voltage and current ranges. The test current of 100mA establishes the baseline operating point, though maximum current ratings provide operational headroom.

Luminous Flux Performance: The substitute must deliver comparable luminous flux output at the test current to maintain illumination levels.

Mounting and Package Compatibility: Surface mount technology with compatible footprint dimensions ensures mechanical and electrical integration into existing PCB designs.

Compliance and Status: Active product status and current compliance certifications (RoHS, REACH) ensure long-term supply availability and regulatory adherence.

The Lumileds LUXEON 3030 2D (L130-2780003000W21) qualifies as a substitute based on matching color temperature, CRI, surface mount configuration, and active product status with superior thermal characteristics and higher luminous efficiency.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The Lumileds LUXEON 3030 2D (L130-2780003000W21) is the qualified substitute for the Samsung LM362A (SPMWHT325AD5YBWMS0).

Justification Based on Compliance and Status:

The LUXEON 3030 2D maintains active product status, ensuring continued availability and manufacturer support. It carries ROHS3 compliance, exceeding the RoHS compliance of the original part and meeting current regulatory requirements. REACH Unaffected status confirms no substance of concern restrictions.

Performance Characteristics:

The substitute delivers 84lm at 120mA test current compared to 65lm at 100mA for the original part, representing a 29% increase in luminous flux output. Luminous efficiency improves from 109 lm/W to 115 lm/W. Forward voltage increases marginally from 5.96V to 6.1V, a 0.14V difference within typical circuit tolerance margins.

Thermal Advantages:

Thermal resistance improves from 15°C/W to 12°C/W, providing superior heat dissipation characteristics for thermal-constrained applications.

Package Considerations:

The substitute uses a 3030 metric package (3.00mm x 3.00mm) compared to the original 3623 package (3.60mm x 2.30mm). PCB footprint redesign is required. The substitute height of 0.62mm is lower than the original 0.70mm, providing clearance advantages in space-constrained designs.

Moisture Sensitivity:

The substitute carries MSL 3 (168 Hours) compared to MSL 2A (4 Weeks) for the original part. This represents a change in moisture handling requirements during storage and assembly processes.

Frequently Asked Questions (FAQ)

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

A: Direct replacement requires circuit evaluation. The forward voltage difference of 0.14V (5.96V to 6.1V) is typically accommodated by standard LED driver circuits. However, the increased test current (120mA vs. 100mA) and higher luminous flux output require verification that the application's current-limiting circuit and power supply can accommodate these parameters without exceeding component ratings.

Q: What are the footprint implications of substituting these parts?

A: The original Samsung LM362A uses a 2-SMD, No Lead 3623 package (3.60mm x 2.30mm). The Lumileds substitute uses a 1212 (3030 Metric) package (3.00mm x 3.00mm). PCB layout modification is necessary. The substitute is smaller in one dimension (2.30mm to 3.00mm width) and shorter in height (0.70mm to 0.62mm), requiring new footprint design and reflow profile validation.

Q: Are there color rendering differences between these parts?

A: Both parts maintain a CRI of 80 and operate at 2700K warm white color temperature. Color rendering characteristics are equivalent for applications requiring this specification level.

Q: What is the impact of the moisture sensitivity level change?

A: The original part carries MSL 2A (4 Weeks), while the substitute carries MSL 3 (168 Hours). MSL 3 allows extended dry storage periods compared to MSL 2A. This change is favorable for supply chain management and reduces moisture-related reflow failures during assembly.

Q: How does the thermal resistance improvement affect application design?

A: The substitute's thermal resistance of 12°C/W compared to the original 15°C/W represents a 20% improvement in heat dissipation efficiency. This allows higher sustained current operation or reduced thermal stress in thermally constrained applications. Applications operating at maximum current ratings benefit from improved thermal performance.

Q: Is the increased luminous flux output compatible with existing optical designs?

A: The 29% increase in luminous flux (65lm to 84lm) at comparable test currents will increase illumination output. Applications with fixed optical geometry will experience brighter output. Optical design review is necessary if the application requires specific illumination levels or has brightness-sensitive components.

Q: What compliance advantages does the substitute provide?

A: The substitute carries ROHS3 compliance and REACH Unaffected status, meeting current and anticipated regulatory requirements. The original part's RoHS compliance status does not specify the version level. ROHS3 compliance ensures compatibility with current manufacturing and end-of-life requirements in regulated markets.
