Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT325AD5YBTMS0 is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Color and Color Temperature: Both the main part and substitute must deliver white light at 4000K (neutral white) to maintain consistent color appearance in end-use applications.

Luminous Flux and Efficacy: The substitute must deliver comparable luminous output (70 lm nominal) and maintain similar or superior luminous efficacy to ensure equivalent brightness performance.

Electrical Characteristics: Forward voltage, test current, and maximum current ratings must be compatible with existing circuit designs. Variations in these parameters require circuit redesign and validation.

Color Rendering Index (CRI): A CRI of 80 is specified for the main part. Substitutes must maintain this CRI value to preserve color fidelity in lighting applications.

Viewing Angle: The 120° viewing angle defines the light distribution pattern. Substitutes with different viewing angles may alter the optical performance of the end application.

Package and Mounting: Surface-mount package type and physical dimensions determine PCB compatibility and assembly feasibility. Package changes require layout redesign.

Compliance and Certifications: RoHS compliance and moisture sensitivity level (MSL) ratings must be maintained to satisfy regulatory requirements and manufacturing process conditions.

The MP-3030-1100-40-80 manufactured by Luminus Devices Inc. is identified as a substitute based on matching color, color temperature, CRI, and mounting type. However, significant differences exist in electrical characteristics and package dimensions that require engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Compliance Considerations:

Both the SPMWHT325AD5YBTMS0 and MP-3030-1100-40-80 maintain RoHS compliance, satisfying regulatory requirements for hazardous substance restrictions. The Luminus MP-3030 carries ROHS3 certification and is REACH unaffected, providing additional regulatory assurance for applications subject to extended environmental compliance requirements.

Product Status Impact:

The SPMWHT325AD5YBTMS0 is classified as obsolete, indicating Samsung has discontinued manufacturing and support. The MP-3030-1100-40-80 is classified as "Not For New Designs," indicating Luminus has limited this part to existing customer applications and does not recommend it for new product development. Both statuses indicate limited long-term availability and support.

Electrical Compatibility:

The MP-3030-1100-40-80 operates at 3.0V forward voltage compared to 5.96V for the SPMWHT325AD5YBTMS0. This 2.96V difference requires circuit redesign, including modifications to current-limiting resistors, power supply voltage, and driver circuitry. Direct pin-for-pin substitution is not feasible without electrical redesign.

Mechanical Compatibility:

The MP-3030-1100-40-80 uses a 3030 metric package (3.00 × 3.00 mm) versus the 3623 package (3.60 × 2.30 mm) of the main part. Package footprints differ, requiring PCB layout modification. The MP-3030 is 0.18 mm shorter in seated height, which may affect optical alignment in applications with tight height constraints.

Optical Performance:

Both parts deliver neutral white light at 4000K with CRI 80. The MP-3030-1100-40-80 delivers 67 lm at 150 mA test current compared to 70 lm at 100 mA for the SPMWHT325AD5YBTMS0. The Luminus part exhibits superior luminous efficacy (149 lm/W versus 117 lm/W), indicating more efficient light generation. The viewing angle differs by 10° (110° versus 120°), which affects light distribution patterns.

Thermal Performance:

The MP-3030-1100-40-80 exhibits superior thermal performance with 11°C/W thermal resistance compared to 15°C/W for the SPMWHT325AD5YBTMS0. Lower thermal resistance improves heat dissipation and may extend component lifetime in thermally constrained applications.

Moisture Sensitivity:

The SPMWHT325AD5YBTMS0 carries MSL 2A (4 weeks), while the MP-3030-1100-40-80 carries MSL 3 (168 hours). The main part allows longer shelf life without moisture exposure. The substitute requires more frequent baking or shorter storage intervals, affecting inventory management and manufacturing logistics.
