SPMWHT541MP5WAWGS4 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WAWGS4 is an LED lighting component from Samsung Semiconductor's LM561B Plus series. This warm white 2700K surface-mount LED operates at 2.95V forward voltage with a test current of 65mA, delivering 31 lumens at 162 lm/W efficiency. The component features a 120° viewing angle and is packaged in a 4-SMD flat-lead configuration with 5630 supplier device package designation. The part maintains Active product status and is suitable for general illumination applications requiring warm white color temperature with high color rendering index (CRI 80).

Equivalent and substitute parts are necessary when the primary part number experiences supply constraints, inventory limitations, or when design flexibility permits selection from functionally compatible alternatives within the same product series.

• Flux @ 25°C, 65mA: 31 lm (30–32 lm range)
• Forward Voltage (Vf): 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Lumens/Watt: 162 lm/W
• CRI: 80
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Height - Seated (Max): 0.031 in (0.80 mm)

Allowable Variation Parameters:

• Physical dimensions (length and width) within mechanical compatibility constraints
• Thermal resistance of package (14–15°C/W range)

The two substitute parts listed below meet all mandatory equivalence criteria and differ only in allowable variation parameters that do not affect electrical or optical performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers maintain Active product status and are manufactured by Samsung Semiconductor, Inc. within the LM561B Plus series. Selection between these equivalents should be based on the following criteria:

SPMWHT541MP5WAWGS4 is the primary reference part with 860 units in stock. This part number is suitable for applications where specific thermal characteristics (14°C/W) are required and RoHS compliance documentation is not a constraint.

SPMWHT541MP5WAWMS4 provides significantly higher inventory availability (25,996 units) with RoHS Compliant certification. The physical length dimension increases to 0.220 inches (5.60 mm) compared to 0.197 inches (5.00 mm) on the primary part. Thermal resistance is 15°C/W. This part is suitable for applications requiring RoHS compliance and where the additional 0.023-inch length dimension is mechanically compatible with the PCB layout.

SPMWHT541MP5WAW0S4 offers the highest inventory availability (45,709 units) with ROHS3 Compliant certification and MSL 2A (4 Weeks) rating. Physical dimensions match the primary part (0.197" L x 0.118" W) with thermal resistance of 15°C/W. This part is suitable for applications requiring ROHS3 compliance and moisture-sensitive handling protocols.

All three parts deliver identical electrical and optical performance at rated test conditions. Selection should prioritize inventory availability, compliance requirements, and mechanical fit constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS4 be used as a direct replacement for SPMWHT541MP5WAWGS4?

A: Yes, with mechanical verification. The substitute part is electrically and optically equivalent across all critical parameters. The primary difference is physical length: SPMWHT541MP5WAWMS4 measures 0.220 inches (5.60 mm) compared to 0.197 inches (5.00 mm) on the primary part. Verify that the additional 0.023-inch length does not create clearance conflicts on the PCB or within the assembly enclosure.

Q: What is the significance of the thermal resistance difference between 14°C/W and 15°C/W?

A: Thermal resistance indicates the temperature rise per watt of dissipated power. At the rated test current of 65 mA and forward voltage of 2.95V, power dissipation is approximately 0.192 watts. The difference between 14°C/W and 15°C/W results in a maximum temperature rise differential of approximately 0.19°C under these conditions. This difference is negligible for most general illumination applications and does not affect component reliability or performance.

Q: Are there any compatibility issues with the RoHS compliance differences?

A: No compatibility issues exist. RoHS compliance is a regulatory and supply-chain requirement, not a functional parameter. SPMWHT541MP5WAWMS4 carries RoHS Compliant certification, while SPMWHT541MP5WAW0S4 carries ROHS3 Compliant certification. Both certifications indicate compliance with hazardous substance restrictions. Selection should be based on the specific regulatory requirements of the end application and target market.

Q: What does MSL 2A (4 Weeks) mean for SPMWHT541MP5WAWMS4 and SPMWHT541MP5WAW0S4?

A: MSL (Moisture Sensitivity Level) 2A indicates that the component can be exposed to ambient conditions of 30°C and 60% relative humidity for up to 4 weeks without requiring baking before reflow soldering. After 4 weeks of exposure, the component must be baked at 125°C for 24 hours to remove absorbed moisture before soldering. This specification applies to both substitute parts and does not affect the primary part SPMWHT541MP5WAWGS4, for which MSL is not specified.

Q: Can these parts be mixed within the same production batch?

A: Yes. All three parts are electrically and optically equivalent at rated test conditions. However, if physical dimensions are critical to PCB layout or assembly clearances, segregate parts by length dimension: 0.197 inches (SPMWHT541MP5WAWGS4 and SPMWHT541MP5WAW0S4) versus 0.220 inches (SPMWHT541MP5WAWMS4). Mixing parts with different physical dimensions in the same assembly may create inconsistent mechanical fit or clearance issues.

Q: What is the base product number SPMWHT541, and how does it relate to these part numbers?

A: SPMWHT541 is the base product number for the LM561B Plus warm white 2700K LED series. The full part numbers include additional suffixes that specify packaging, tape configuration, and other supply-chain attributes. All three equivalent parts share the same base product number, confirming they are variants within the same product family with identical core electrical and optical specifications.
