Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WATKS4 are identified based on strict electrical and mechanical parameter alignment within the LM561B Plus series. The substitution criteria are:

Critical Matching Parameters:

• Color specification: White, Neutral
• Correlated Color Temperature (CCT): 4000K
• Luminous flux @ 25°C, 65mA test current: 33lm (32lm ~ 34lm range)
• Forward voltage (Vf) typical: 2.95V
• Test current: 65mA
• Maximum current rating: 180mA
• Color Rendering Index (CRI): 80
• Viewing angle: 120°
• Package type: 4-SMD, Flat Leads
• Supplier device package: 5630
• Physical dimensions: 0.197" L x 0.118" W (5.00mm x 3.00mm)
• Maximum seated height: 0.031" (0.80mm)
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 2A (4 Weeks)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Thermal resistance variance within acceptable engineering tolerances does not preclude substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SPMWHT541MP5WATKS4, SPMWHT541MP5WAT0S4, and SPMWHT541MP5WATMS4—are Active product status components from Samsung Semiconductor's LM561B Plus series and meet identical electrical and mechanical specifications for direct substitution.

Compliance Considerations:

SPMWHT541MP5WATKS4 and SPMWHT541MP5WAT0S4 carry RoHS Compliant certification. SPMWHT541MP5WATMS4 carries ROHS3 Compliant certification, representing an enhanced compliance standard. All three components meet Moisture Sensitivity Level 2A (4 Weeks) requirements.

Thermal Performance:

SPMWHT541MP5WATKS4 and SPMWHT541MP5WAT0S4 specify 15°C/W thermal resistance. SPMWHT541MP5WATMS4 specifies 16°C/W thermal resistance. This 1°C/W difference does not affect functional equivalence for standard thermal management applications.

Inventory Availability:

SPMWHT541MP5WATKS4: 165,400 Pcs SPMWHT541MP5WAT0S4: 1,057 Pcs SPMWHT541MP5WATMS4: 600,200 Pcs

Component selection may be based on inventory availability and compliance certification requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAT0S4 replace SPMWHT541MP5WATKS4 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical performance (2.95V forward voltage, 65mA test current, 33 lumens), mechanical compatibility (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm dimensions), and thermal characteristics (15°C/W). Both carry RoHS Compliant certification and 2A MSL rating.

Q: What is the difference between SPMWHT541MP5WATMS4 and the other two parts?

A: SPMWHT541MP5WATMS4 is electrically and mechanically identical to SPMWHT541MP5WATKS4 and SPMWHT541MP5WAT0S4. The primary differences are thermal resistance (16°C/W versus 15°C/W) and RoHS certification level (ROHS3 Compliant versus RoHS Compliant). All three deliver 33 lumens at 4000K neutral white with 172 lm/W efficiency.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts share identical package specifications: 4-SMD flat leads, 5630 supplier device package, 5.00mm x 3.00mm footprint, and 0.80mm maximum seated height. No PCB redesign is required for substitution.

Q: What is the significance of the thermal resistance difference?

A: The 1°C/W difference between 15°C/W and 16°C/W thermal resistance is within standard manufacturing tolerance for this component class. Both values support equivalent thermal performance in typical LED lighting applications with standard thermal management.

Q: Do all three parts meet the same moisture sensitivity requirements?

A: Yes. All three parts are rated 2A MSL (Moisture Sensitivity Level 2A, 4 Weeks), indicating identical moisture handling and storage requirements.

Q: Which part should be selected for new designs?

A: Selection is based on application-specific requirements. For RoHS Compliant applications, SPMWHT541MP5WATKS4 or SPMWHT541MP5WAT0S4 are appropriate. For ROHS3 Compliant applications, SPMWHT541MP5WATMS4 is specified. Inventory availability may also influence selection.
