Samsung SPMWHT541MP7WAVUS0 LED Equivalent & Substitute Parts

Part Overview

The Samsung SPMWHT541MP7WAVUS0 is an LM561B Plus warm white LED (3000K) in 5630 surface mount package with 4-SMD flat leads configuration. This part is marked as "Not For New Designs," indicating it has reached end-of-life status. The LM561B Plus series delivers 2.95V forward voltage at 65mA test current with 90 CRI and 120° viewing angle. Finding equivalent or substitute parts is necessary due to the discontinued design status and potential supply constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters that must align for direct replacement:

Primary Compatibility Criteria:

• Color and CCT (3000K warm white)
• CRI (90 minimum)
• Package type (4-SMD, Flat Leads, 5630)
• Mounting type (Surface Mount)
• Physical dimensions (5.00mm x 3.00mm footprint, 0.80mm max height)
• Viewing angle (120°)

Substitutes are grouped into two categories:

1. Direct Series Equivalent (SPMWHT541MP7WAVMS0): Active product with identical LM561B Plus series, same electrical specifications, improved thermal performance (15°C/W vs 20°C/W), and verified luminous flux data at 25°C (26lm, 23-29lm range).

2. Parametric Equivalents (LM281B+ Series): Five variants with different forward voltage and thermal characteristics. These parts maintain 3000K CCT, 90 CRI, 120° viewing angle, and 5630 package compatibility. Key differences include higher test current (150mA vs 65mA), higher maximum current (200mA vs 180mA), and higher thermal resistance (25°C/W vs 20°C/W). Forward voltage variants range from 2.9V to 3.0V.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): SPMWHT541MP7WAVMS0 is the primary substitute. This part maintains identical LM561B Plus series specifications, same forward voltage (2.95V), and test current (65mA). It is an active product with ROHS3 compliance and superior thermal performance (15°C/W). Inventory availability is significantly higher (33,985 pcs vs 1,069 pcs for the main part).

For Parametric Substitution (LM281B+ Series): The five LM281B+ variants are suitable when circuit design accommodates higher test current (150mA vs 65mA) and forward voltage variations (2.9V or 3.0V). These parts are active products with ROHS3 compliance and REACH unaffected status. Selection between 2.9V and 3.0V variants depends on circuit voltage headroom. All LM281B+ parts have higher thermal resistance (25°C/W), requiring thermal design review for high-power applications.

Compliance Considerations: All substitute parts meet ROHS3 compliance, exceeding the RoHS compliance of the original part. The LM281B+ series includes REACH unaffected certification, providing additional regulatory assurance for new designs.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVMS0 be used as a direct drop-in replacement? A: Yes. SPMWHT541MP7WAVMS0 maintains identical electrical specifications (2.95V, 65mA test current, 90 CRI, 3000K) and physical dimensions (5630 package, 5.00mm x 3.00mm, 0.80mm height). The only differences are improved thermal performance and active product status.

Q: What are the key differences between LM561B Plus and LM281B+ series? A: The LM281B+ series operates at higher test current (150mA vs 65mA) and maximum current (200mA vs 180mA). Forward voltage options are 2.9V or 3.0V compared to 2.95V for LM561B Plus. Thermal resistance is higher (25°C/W vs 20°C/W for the main part or 15°C/W for SPMWHT541MP7WAVMS0). All other parameters (color, CCT, CRI, viewing angle, package) remain identical.

Q: Which LM281B+ variant should I select? A: Choose based on circuit forward voltage requirements. SPMWH1228FD7W2V0SJ, SPMWH1228FD7W2VKSJ, and SPMWH1228FD7W2VMSJ operate at 2.9V. SPMWH1228FD7WAV0SJ, SPMWH1228FD7WAVKSJ, and SPMWH1228FD7WAVMSJ operate at 3.0V. The suffix variation (0SJ, KSJ, MSJ) indicates different packaging or tape configurations but does not affect electrical performance.

Q: Are all substitutes compatible with the original PCB layout? A: Yes. All substitute parts use identical 5630 package (4-SMD, Flat Leads) with matching dimensions (5.00mm x 3.00mm) and maximum seated height (0.80mm). PCB footprints and reflow profiles remain compatible.

Q: What compliance certifications apply to these parts? A: SPMWHT541MP7WAVMS0 and all LM281B+ variants are ROHS3 compliant. The LM281B+ series additionally carries REACH unaffected certification. All parts are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Why is thermal resistance different between variants? A: Thermal resistance variations (15°C/W, 20°C/W, 25°C/W) reflect different die and package designs. Higher thermal resistance requires better thermal management in high-current applications. SPMWHT541MP7WAVMS0 offers the best thermal performance among active products.
