Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WATNS4 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match):

• Color: White, Neutral
• CCT: 4000K
• Forward Voltage (Vf): 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Flux @ 25°C: 33lm (32–34lm range)
• Lumens/Watt: 172 lm/W
• CRI: 80
• Viewing Angle: 120°

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
• Packaging: Tape & Reel (TR)

Compliance Parameters (Must Match):

• Series: LM561B Plus
• Product Status: Active
• Moisture Sensitivity Level: 2A (4 Weeks)

The identified substitute parts SPMWHT541MP5WAT0S4 and SPMWHT541MP5WATMS4 meet all electrical and mechanical parameter requirements for direct substitution with the main part SPMWHT541MP5WATNS4.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SPMWHT541MP5WATNS4, SPMWHT541MP5WAT0S4, and SPMWHT541MP5WATMS4—are classified as Active product status from Samsung Semiconductor and are suitable for direct substitution based on electrical and mechanical parameter equivalence.

Compliance Considerations:

SPMWHT541MP5WATNS4 and SPMWHT541MP5WAT0S4 carry RoHS Compliant certification. SPMWHT541MP5WATMS4 carries ROHS3 Compliant certification, which represents an updated compliance standard. Both certifications satisfy RoHS requirements; ROHS3 reflects current regulatory alignment.

Thermal Resistance Variance:

SPMWHT541MP5WATNS4 and SPMWHT541MP5WAT0S4 specify thermal resistance of 15°C/W. SPMWHT541MP5WATMS4 specifies 16°C/W. This 1°C/W difference is within acceptable tolerance for thermal management in typical LED lighting applications and does not preclude substitution.

Inventory Availability:

SPMWHT541MP5WATNS4: 825 Pcs in stock SPMWHT541MP5WAT0S4: 1057 Pcs in stock SPMWHT541MP5WATMS4: 600200 Pcs in stock

Selection among these parts may be driven by inventory requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAT0S4 replace SPMWHT541MP5WATNS4 in existing designs?

A: Yes. Both parts share identical electrical parameters (2.95V forward voltage, 65mA test current, 33lm flux, 4000K CCT, 80 CRI), mechanical dimensions (5.00mm × 3.00mm, 0.80mm height), and package configuration (4-SMD, Flat Leads, 5630). Thermal resistance is identical at 15°C/W. Both carry RoHS Compliant certification and Active product status.

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

A: SPMWHT541MP5WATMS4 is electrically and mechanically identical to SPMWHT541MP5WATNS4 and SPMWHT541MP5WAT0S4 across all critical parameters. The differences are: (1) thermal resistance is 16°C/W versus 15°C/W, and (2) RoHS certification is ROHS3 Compliant versus RoHS Compliant. These differences do not affect functional substitution in standard LED lighting applications.

Q: Are all three parts suitable for surface-mount assembly?

A: Yes. All three parts are classified as Surface Mount with 4-SMD, Flat Leads package configuration and 5630 supplier device package. Dimensions are identical: 5.00mm length × 3.00mm width × 0.80mm maximum seated height. All are supplied in Tape & Reel (TR) packaging for automated assembly.

Q: Do these parts have the same moisture sensitivity requirements?

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

Q: Can I mix these parts in the same production batch?

A: All three parts meet identical electrical and mechanical specifications for the LM561B Plus 4000K neutral white LED. They are functionally interchangeable. However, thermal resistance variance (15°C/W versus 16°C/W) and RoHS certification differences (RoHS Compliant versus ROHS3 Compliant) should be documented in design records if mixed sourcing is employed.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is determined by equivalence in: (1) electrical parameters (color, CCT, forward voltage, test current, maximum current, flux output, lumens/watt, CRI, viewing angle), (2) mechanical parameters (package type, dimensions, height, mounting type), (3) series designation (LM561B Plus), (4) product status (Active), and (5) handling requirements (MSL). All identified substitutes meet these criteria.
