SPMWHT325AD5YBR0SC

Part Overview

The Samsung Semiconductor LM362A (SPMWHT325AD5YBR0SC) is a cool white LED with a color temperature of 5000K, designed for surface mount applications. This product is classified as obsolete, making identification of equivalent and substitute components essential for ongoing production and legacy system maintenance. The LM362A delivers 86 lm at 100mA test current with a forward voltage of 5.96V and is packaged in a compact 2-SMD, No Lead configuration measuring 3.60mm × 2.30mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Samsung LM362A is based on maintaining functional equivalence across the following critical parameters:

• Color and CCT: Both components must emit cool white light at 5000K
• Luminous Flux: Output must be within the operational range of 76–96 lm at the specified test current, with typical value near 86 lm
• Forward Voltage: Operating voltage must be compatible with 5.96V nominal input
• Test/Operating Current: Primary test current baseline of 100mA with acceptable range up to 120mA for equivalent operation
• CRI (Color Rendering Index): Minimum CRI of 80 for color accuracy consistency
• Package Type: Surface mount configuration with compatible footprint for PCB integration
• Thermal Performance: Package thermal resistance and height clearance must support existing thermal management design
• Compliance Status: RoHS compliance and MSL rating must meet or exceed the original specification

The Lumileds L130-5080003000W21 (LUXEON 3030 2D) meets these substitution criteria with active product status and enhanced thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Lumileds L130-5080003000W21 is the suitable substitute for the obsolete Samsung LM362A based on the following factors:

Product Status and Availability: The Samsung LM362A is classified as obsolete, eliminating it as a long-term component source. The Lumileds LUXEON 3030 2D maintains active product status with established supply chain availability, ensuring sustained procurement for production and field replacements.

Compliance and Regulatory Alignment: Both components meet RoHS compliance requirements. The Lumileds part achieves ROHS3 compliance, representing current regulatory standards. Both components are classified under identical HTSUS and ECCN codes (8541.41.0000 and EAR99, respectively), ensuring consistent export and import compliance.

Thermal Performance: The Lumileds substitute exhibits superior thermal characteristics with 12°C/W package thermal resistance compared to the original 15°C/W, and lower seated height (0.62mm vs. 0.70mm), providing improved thermal management in densely populated PCB layouts.

Functional Compatibility: Color temperature, CRI, and luminous flux specifications align within acceptable engineering tolerances. Forward voltage differential (6.1V vs. 5.96V) is minor and manageable in typical LED driver circuit designs with 0.3V margin tolerance. The slight increase in test current (120mA vs. 100mA) and lumens per watt reduction (131 vs. 144 lm/W) do not compromise application performance in standard lighting configurations.

Package Considerations: Footprint dimensions differ (3.00mm × 3.00mm vs. 3.60mm × 2.30mm). PCB layout modification is required to accommodate the LUXEON 3030 2D package. The more compact height of the substitute (0.62mm) offers clearance advantages in space-constrained assemblies.

Frequently Asked Questions (FAQ)

Q: What makes the Lumileds LUXEON 3030 2D an acceptable substitute for the obsolete Samsung LM362A?

A: The Lumileds part maintains functional equivalence through matching color temperature (5000K), color rendering index (CRI 80), and luminous flux output within acceptable tolerance (96 lm vs. 86 lm nominal). Both components are surface mount, cool white LEDs with compatible electrical operating ranges. The primary difference is package format, which requires PCB layout adjustment but does not affect the electrical or optical performance of the LED itself.

Q: Are there package compatibility issues between the LM362A and LUXEON 3030 2D?

A: Yes. The Samsung LM362A uses a 2-SMD, No Lead package (3623) with 3.60mm × 2.30mm footprint. The Lumileds substitute uses a 1212 (3030 Metric) package with a 3.00mm × 3.00mm footprint. PCB redesign is necessary to accommodate the different package geometry. The Lumileds part is slightly lower in profile (0.62mm vs. 0.70mm), which may provide assembly advantages in compact designs.

Q: Will the forward voltage difference affect circuit operation?

A: The forward voltage difference is 0.14V (6.1V for Lumileds vs. 5.96V for Samsung). This variation is minor and falls within standard LED driver circuit tolerance margins, which typically accommodate 0.3V to 0.5V variation. LED driver designs with current regulation will automatically compensate for this small voltage differential without circuit modification.

Q: What is the impact of the test current difference (120mA vs. 100mA)?

A: The Lumileds substitute operates at 120mA test current versus 100mA for the original part. This 20mA difference is within the absolute maximum current rating of both components (240mA and 200mA, respectively). Circuit current limiting must be verified to ensure safe operation. Most LED driver circuits are current-regulated and will naturally operate the Lumileds part at the design current specification of your application, not necessarily at the part's test current rating.

Q: How do moisture sensitivity levels compare?

A: The Samsung LM362A has MSL 2A (4-week shelf life at 30°C/60% RH). The Lumileds part has MSL 3 (168-hour shelf life at 40°C/90% RH). The Lumileds component requires stricter moisture control and shorter shelf life management. Procurement and storage procedures must account for the more stringent MSL requirement to prevent solder reflow defects.

Q: Is the footprint change a critical barrier to substitution?

A: PCB footprint modification is required, but it is not a technical barrier to substitution. The change is manageable through standard PCB redesign processes. The Lumileds part's slightly larger overall dimensions (3.00mm × 3.00mm) may actually provide better mechanical stability and thermal performance compared to the elongated original footprint, though space constraints must be verified in your specific application.
