Samsung SPMWHT541MP5WATRS4 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WATRS4 is a Samsung Semiconductor LM561B Plus white neutral LED in 5630 surface mount package configuration. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The part delivers 33 lumens at 65mA test current with 4000K color temperature and 80 CRI, suitable for general illumination applications requiring neutral white output.

Due to its Not For New Designs status, equivalent substitute parts from the active LM561B Plus product line are available to support ongoing production requirements and design transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for SPMWHT541MP5WATRS4 are determined by strict equivalence across 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 L × 3.00mm W
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount
• Packaging: Tape & Reel (TR)

Environmental Parameters (Must Match):

• Moisture Sensitivity Level: 2A (4 Weeks)

All five substitute parts listed below maintain identical electrical, mechanical, and environmental specifications. Variations in thermal resistance and RoHS compliance status are noted in the parameter comparison table but do not affect functional substitutability for the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are functionally equivalent to SPMWHT541MP5WATRS4 across all critical electrical, mechanical, and environmental parameters. Selection among substitutes should be based on the following factors:

Product Status Consideration: The main part SPMWHT541MP5WATRS4 carries Not For New Designs status. All substitute parts are classified as Active, making them suitable for new production and long-term supply continuity.

Compliance Status:

• SPMWHT541MP5WAT0S4, SPMWHT541MP5WATKS4, and SPMWHT541MP5WATNS4 carry RoHS Compliant certification
• SPMWHT541MP5WATMS4 and SPMWHT541MP5WATSS4 carry ROHS3 Compliant certification

Both RoHS and ROHS3 compliance satisfy standard regulatory requirements. ROHS3 represents the current regulatory standard.

Thermal Resistance Variation: Thermal resistance ranges from 14°C/W to 16°C/W across the substitute group. This 2°C/W variation is within typical manufacturing tolerance for this package class and does not affect functional substitutability for standard thermal management applications.

Inventory Availability: SPMWHT541MP5WATMS4 offers the highest inventory level (600,200 pcs), followed by SPMWHT541MP5WATKS4 (165,400 pcs). These parts provide optimal supply security for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATRS4 be directly replaced with any of the listed substitute parts?

A: Yes. All five substitute parts maintain identical electrical output (33 lm at 65mA, 2.95V forward voltage, 4000K color temperature, 80 CRI), mechanical package configuration (5630 4-SMD, Flat Leads), and environmental specifications (MSL 2A). Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates the part has reached end-of-life and Samsung is no longer recommending it for new product development. All substitute parts carry Active status, confirming ongoing manufacturing and supply support.

Q: Are there differences in thermal performance between the substitute parts?

A: Thermal resistance varies between 14°C/W and 16°C/W. This 2°C/W range represents normal manufacturing variation within the 5630 package class and does not create functional differences for standard thermal management scenarios. Applications with extreme thermal constraints should reference detailed thermal modeling data.

Q: Do the RoHS and ROHS3 compliance differences affect substitutability?

A: No. Both RoHS and ROHS3 compliance satisfy current regulatory requirements for electronic components. ROHS3 represents the current standard, but both certifications are functionally equivalent for component selection purposes.

Q: Which substitute part should be selected for maximum supply continuity?

A: SPMWHT541MP5WATMS4 provides the highest inventory level (600,200 pcs) and carries ROHS3 compliance. SPMWHT541MP5WATKS4 offers the second-highest inventory (165,400 pcs) with RoHS compliance. Both support long-term production requirements.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging with MSL 2A (4 Weeks) moisture sensitivity level, matching the main part specification.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical mechanical dimensions (5.00mm L × 3.00mm W, 0.80mm max height), flat lead configuration, and surface mount package ensure direct PCB compatibility without layout modification.
