LED LM362A SPMWHT325AD5YBV0S0 Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM362A (SPMWHT325AD5YBV0S0) is a warm white LED lighting component rated at 3000K color temperature with 66 lumens output at 100mA test current. This surface mount LED is designed for applications requiring warm white illumination with a 120° viewing angle and operates at a forward voltage of 5.96V. The product is currently classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Samsung LM362A is determined by strict alignment of the following critical parameters:

Color and CCT Match: The substitute must provide White, Warm illumination at 3000K color temperature to maintain consistent color rendering in the application.

Luminous Flux Compatibility: The substitute must deliver comparable lumen output at its specified test current. The LM362A produces 66 lumens at 100mA; substitutes must operate within acceptable flux ranges for the intended application.

Electrical Characteristics: Forward voltage and maximum current ratings must be compatible with existing circuit designs. The LM362A operates at 5.96V typical with a 200mA maximum rating.

Mounting and Package Compatibility: Surface mount configuration is required. While the LM362A uses a 3623 package (2-SMD, No Lead) with 3.60 × 2.30mm footprint, substitute parts may use different package designations provided they are surface mountable and fit within PCB layout constraints.

Compliance and Certifications: RoHS compliance status and ECCN classification must be verified for regulatory and supply chain requirements.

The Lumileds L130-3090003000W21 (LUXEON 3030 2D) meets these substitution criteria through matching color temperature, warm white spectrum, comparable luminous flux output, and surface mount configuration.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Samsung LM362A is classified as obsolete, while the Lumileds L130-3090003000W21 is active. Active product status ensures ongoing availability, technical support, and supply chain stability for new designs and production continuity.

Compliance Alignment: Both components are RoHS compliant. The Lumileds part carries ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory documentation for applications requiring strict environmental compliance verification.

Electrical Performance: The Lumileds substitute operates at 6.1V forward voltage compared to the Samsung 5.96V. This 0.14V difference is within typical LED tolerance ranges and requires circuit verification to confirm compatibility with existing current-limiting resistor or driver designs. The Lumileds part supports higher maximum current (240mA vs. 200mA), providing additional operational headroom.

Luminous Output: The Lumileds L130-3090003000W21 delivers 82 lumens at 120mA test current, compared to 66 lumens at 100mA for the Samsung part. Both achieve comparable efficiency at approximately 111–112 lm/W. The higher absolute flux output of the Lumileds part may require brightness adjustment in the application circuit if exact luminous intensity matching is required.

Color Rendering: The Lumileds substitute provides CRI of 90 compared to the Samsung CRI of 80. This higher color rendering index indicates improved color accuracy and is suitable for applications where color fidelity is important.

Thermal Performance: The Lumileds part exhibits lower thermal resistance (12°C/W vs. 15°C/W), indicating superior heat dissipation characteristics.

Package Footprint: The Lumileds 3030 package (3.00 × 3.00mm) differs from the Samsung 3623 package (3.60 × 2.30mm). PCB layout modification is required. The Lumileds part is slightly lower in height (0.62mm vs. 0.70mm), which may provide clearance advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the Lumileds L130-3090003000W21 directly replace the Samsung LM362A without circuit modification?

A: Direct replacement requires circuit verification. The forward voltage difference (6.1V vs. 5.96V) and higher test current (120mA vs. 100mA) necessitate confirmation that existing current-limiting resistors or LED drivers accommodate these parameters. PCB layout modification is required due to different package footprints (3030 vs. 3623).

Q: What is the significance of the different package designations (3623 vs. 3030)?

A: Package designation indicates physical dimensions and mounting footprint. The Samsung 3623 is a 2-SMD, No Lead package measuring 3.60 × 2.30mm. The Lumileds 3030 is a 1212 (3030 Metric) package measuring 3.00 × 3.00mm. These are distinct footprints requiring separate PCB pad layouts. Substitution requires PCB redesign or use of an adapter substrate.

Q: Why does the Lumileds part have higher luminous flux (82lm vs. 66lm)?

A: The difference reflects test current variation (120mA vs. 100mA) and inherent manufacturing differences between LED designs. The Lumileds part is tested at higher current, resulting in higher absolute flux output. Both achieve similar efficiency (111–112 lm/W). Application brightness requirements determine whether this difference is acceptable or requires circuit adjustment.

Q: Is the CRI difference (90 vs. 80) significant for substitution?

A: CRI indicates color rendering accuracy. The Lumileds CRI of 90 provides superior color fidelity compared to the Samsung CRI of 80. For applications where color accuracy is critical (retail, display, photography), the higher CRI is beneficial. For general illumination, both values are acceptable.

Q: What does the MSL rating difference mean for handling and storage?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption risk during storage. The Samsung part is MSL 2A (4 weeks floor life), while the Lumileds part is MSL 3 (168 hours floor life). The Lumileds part requires more careful moisture control during storage and handling. Both require proper baking procedures before reflow soldering if floor life is exceeded.

Q: Are there viewing angle considerations for substitution?

A: The Samsung LM362A specifies a 120° viewing angle. The Lumileds L130-3090003000W21 does not specify viewing angle in the provided data. Confirm viewing angle requirements for the application. If narrow beam angle is critical, additional verification with the Lumileds datasheet is necessary.

Q: What thermal management differences should be considered?

A: The Lumileds part has lower thermal resistance (12°C/W vs. 15°C/W), indicating better heat dissipation. In high-current or high-ambient-temperature applications, the Lumileds part may operate at lower junction temperatures, potentially extending operational life and maintaining more stable color output.
