Key Parameters

Substitute Part Grouping Explanation

Substitution of the Samsung LM362A (SPMWHT325AD5YBU0SC) is determined by the following critical parameters:

Primary Substitution Criteria:

• Color specification: White, Warm
• Color temperature: 3500K
• Mounting type: Surface Mount
• Luminous flux range: Minimum 73 lm at 25°C, typical 83 lm
• Forward voltage compatibility: 5.96V nominal operation
• Test current: 100mA baseline
• Color Rendering Index: 80 or higher
• Viewing angle: 120° or greater
• RoHS compliance status

Secondary Compatibility Factors:

• Package form factor and footprint dimensions
• Thermal resistance characteristics
• Maximum current rating: 200mA or higher
• Moisture sensitivity classification

The Lumileds L130-3590003000W21 (LUXEON 3030 2D) meets the primary substitution criteria through matching color temperature (3500K), warm white color specification, surface mount configuration, and luminous flux output (88 lm typical at 120mA). Both components operate within compatible voltage ranges and deliver equivalent lighting performance for warm white applications.

Engineering Selection Recommendations

Product Status Consideration: The Samsung LM362A has reached obsolete status, making the active Lumileds L130-3590003000W21 the appropriate substitute for ongoing production and new designs requiring warm white 3500K LED specifications.

Compliance and Certification: Both components maintain RoHS compliance. The Lumileds L130-3590003000W21 carries ROHS3 Compliant status and is REACH Unaffected, providing enhanced regulatory alignment for current manufacturing standards. The Samsung LM362A meets RoHS Compliant requirements.

Electrical Compatibility: Forward voltage differs by 0.14V (Samsung 5.96V vs. Lumileds 6.1V). Circuit designs operating the Samsung LM362A at 100mA test current accommodate the Lumileds substitute at 120mA test current without functional degradation. Both components support maximum currents of 200mA and 240mA respectively, providing adequate margin for typical lighting applications.

Optical Performance: Both LEDs deliver equivalent luminous flux in the warm white spectrum. The Lumileds L130-3590003000W21 provides superior color rendering (CRI 90 vs. 80), beneficial for applications requiring enhanced color accuracy. Viewing angles are comparable (120° vs. 116°).

Thermal Characteristics: The Lumileds substitute exhibits improved thermal resistance (12°C/W vs. 15°C/W), supporting enhanced heat dissipation in compact designs.

Packaging and Footprint: Package form factors differ. The Samsung LM362A uses 2-SMD, No Lead (3623) configuration at 3.60 × 2.30 mm. The Lumileds L130-3590003000W21 uses 1212 (3030 Metric) at 3.00 × 3.00 mm. PCB layout modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the Lumileds L130-3590003000W21 directly replace the Samsung LM362A without circuit modification?

A: Electrical substitution is feasible with minor circuit adjustments. The forward voltage difference (0.14V) requires verification of current-limiting resistor values or driver circuit settings. The test current increase from 100mA to 120mA is within acceptable operating margins for most lighting applications. PCB footprint changes are mandatory due to different package geometries (3623 vs. 3030).

Q: What are the key differences in thermal performance?

A: The Lumileds L130-3590003000W21 provides superior thermal characteristics with 12°C/W thermal resistance compared to the Samsung LM362A at 15°C/W. This 3°C/W improvement supports better heat dissipation in thermally constrained designs.

Q: Are there color rendering differences between these LEDs?

A: Yes. The Lumileds L130-3590003000W21 delivers CRI 90, compared to CRI 80 for the Samsung LM362A. Both maintain 3500K color temperature. The higher CRI of the Lumileds substitute provides enhanced color accuracy and is preferred for applications where color fidelity is critical.

Q: What moisture sensitivity considerations apply to substitution?

A: The Samsung LM362A carries MSL 2A (4 Weeks), while the Lumileds L130-3590003000W21 carries MSL 3 (168 Hours). The Lumileds component requires more frequent reflow processing within its moisture sensitivity window. Storage and handling procedures must align with the more stringent MSL 3 classification.

Q: Are both components RoHS compliant?

A: Yes. The Samsung LM362A is RoHS Compliant. The Lumileds L130-3590003000W21 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for European and international markets.

Q: What viewing angle differences exist?

A: The Samsung LM362A provides 120° viewing angle, while the Lumileds L130-3590003000W21 provides 116° viewing angle. This 4° difference is negligible for most lighting applications and does not impact functional compatibility.

Q: How do the luminous flux outputs compare?

A: The Samsung LM362A delivers 83 lm (range 73–93 lm) at 100mA test current. The Lumileds L130-3590003000W21 delivers 88 lm typical at 120mA test current. The Lumileds substitute provides approximately 6% higher flux output, supporting equivalent or enhanced lighting performance.
