Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAT0S4 are identified based on strict parametric equivalence within the LM561B Plus series. The substitution logic is governed by the following critical parameters:

Electrical Parameters (Must Match):

• Color: White, Neutral
• CCT: 4000K
• Flux @ 25°C, 65mA: 33 lm (32–34 lm range)
• Forward Voltage (Vf): 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Lumens per Watt: 172 lm/W
• CRI: 80

Mechanical Parameters (Must Match):

• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Size / Dimension: 5.00mm × 3.00mm
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount
• Viewing Angle: 120°

Compliance & Environmental Parameters (Must Match):

• Series: LM561B Plus
• Packaging: Tape & Reel (TR)
• Moisture Sensitivity Level: 2A (4 Weeks)
• RoHS Status: RoHS Compliant or ROHS3 Compliant

The substitute part SPMWHT541MP5WATMS4 meets all electrical and mechanical requirements. Minor variations in thermal resistance (15°C/W vs. 16°C/W) and RoHS certification level (RoHS Compliant vs. ROHS3 Compliant) do not affect functional substitutability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541MP5WAT0S4 and SPMWHT541MP5WATMS4 are Active product status components from Samsung Semiconductor's LM561B Plus series. Both parts are RoHS compliant, meeting environmental and regulatory requirements for current production use.

Selection Criteria Based on Provided Data:

The SPMWHT541MP5WAT0S4 carries RoHS Compliant certification and maintains a thermal resistance of 15°C/W. The SPMWHT541MP5WATMS4 carries ROHS3 Compliant certification and maintains a thermal resistance of 16°C/W. Both certifications satisfy RoHS requirements; ROHS3 represents an updated compliance standard. The 1°C/W difference in thermal resistance is within acceptable engineering tolerance for LED lighting applications and does not affect functional performance within the specified operating parameters.

Selection between these parts should be based on:

• Inventory availability and supply chain requirements
• Specific compliance documentation requirements (RoHS vs. ROHS3)
• Thermal design margin requirements in the application circuit
• Lead time and cost considerations

Both parts are electrically and mechanically interchangeable within designs specified for the SPMWHT541MP5WAT0S4.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATMS4 be used as a direct replacement for SPMWHT541MP5WAT0S4?

A: Yes. Both parts are identical in electrical performance (color, CCT, flux, forward voltage, current ratings, CRI, and viewing angle) and mechanical specifications (package type, dimensions, mounting). The thermal resistance difference (15°C/W vs. 16°C/W) and RoHS certification level difference do not prevent direct substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the third iteration of RoHS compliance standards. Both certifications satisfy RoHS environmental requirements. ROHS3 reflects updated regulatory standards. The choice between them depends on specific compliance documentation requirements for your application or region.

Q: Are the 5630 package dimensions identical between both parts?

A: Yes. Both parts use the 5630 supplier device package with identical dimensions of 5.00mm × 3.00mm and maximum seated height of 0.80mm. Both are 4-SMD, Flat Leads configurations suitable for surface-mount assembly.

Q: Does the 1°C/W thermal resistance difference affect performance?

A: The thermal resistance difference (15°C/W vs. 16°C/W) is minimal and within normal manufacturing tolerance for LED components. Both values support the same operating current range (65mA test, 180mA maximum) and flux output (33 lm). Selection should consider application-specific thermal design margins.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts carry MSL 2A (4 Weeks) rating. This indicates the parts must be stored in controlled humidity conditions and used within 4 weeks of package opening under standard moisture conditions.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both SPMWHT541MP5WAT0S4 and SPMWHT541MP5WATMS4 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the CRI value and why does it matter?

A: Both parts have a CRI (Color Rendering Index) of 80. CRI measures how accurately a light source renders colors compared to natural daylight. A CRI of 80 is suitable for general lighting applications where moderate color accuracy is required.

Q: Can these parts operate at currents other than 65mA?

A: Yes. The test current of 65mA is the reference point for flux and efficiency specifications. Both parts support operation up to a maximum current of 180mA. Operating at different currents will affect flux output and thermal characteristics accordingly.
