Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAWMS1 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Series family: LM561B or LM561B Plus
• Color specification: White, Warm
• Correlated Color Temperature (CCT): 2700K
• Mounting type: Surface Mount
• Package format: 5630 (4-SMD configuration)
• Forward voltage range: Compatible with 2.9V nominal specification
• Test current: 65mA nominal operation
• Maximum current rating: Must accommodate circuit design requirements

Mechanical Compatibility Requirements:

• Package dimensions must fit PCB footprint designed for 5630 format
• Height constraints must not exceed application assembly clearance
• Lead configuration must be compatible with existing solder pad layout

The SPMWHT541MP5WAWMS4 (LM561B Plus variant) qualifies as a direct substitute based on matching series family, color, CCT, mounting type, and package format, with electrical parameters within acceptable operating ranges for the specified application.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SPMWHT541MP5WAWMS4 is a valid substitute for the SPMWHT541MD5WAWMS1 based on electrical and mechanical compatibility within the LM561B product family. Both components share identical color temperature (2700K), mounting type (Surface Mount), and package format (5630). Forward voltage differs by 0.05V (2.9V vs. 2.95V), which is within typical LED tolerance ranges and does not preclude substitution in standard circuit designs.

Product Status Consideration:

The main part (SPMWHT541MD5WAWMS1) carries "Not For New Designs" status, indicating Samsung has discontinued active support. The substitute part (SPMWHT541MP5WAWMS4) maintains "Active" status, ensuring ongoing availability and manufacturing support.

Compliance and Certification:

Both components are RoHS Compliant and carry identical MSL ratings (2A, 4 Weeks), confirming equivalent environmental and handling requirements. ECCN and HTSUS classifications are identical, supporting regulatory equivalence.

Mechanical Considerations:

The substitute part exhibits a 0.6mm increase in length (5.60mm vs. 5.00mm) and 0.1mm reduction in height (0.80mm vs. 0.90mm). PCB footprint compatibility must be verified for applications with tight spatial constraints. The substitute features improved thermal resistance (15°C/W vs. 16°C/W), providing marginal thermal performance advantage.

Electrical Performance:

The substitute part supports higher maximum current (180mA vs. 150mA) and provides documented photometric performance (31 lm at 65mA, 162 lm/W efficiency, 80 CRI), enabling more precise luminous output specification in new circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS4 directly replace SPMWHT541MD5WAWMS1 in existing PCB designs?

A: Direct replacement is feasible for most applications. The substitute maintains identical color temperature (2700K), forward voltage within 0.05V tolerance, and equivalent test current (65mA). Verify PCB footprint accommodates the 0.6mm length increase (5.60mm vs. 5.00mm). Lead configuration differs (flat leads vs. flat lead exposed pad); confirm solder pad compatibility with your assembly process.

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

A: This designation indicates Samsung has concluded active development and support for the SPMWHT541MD5WAWMS1. Existing inventory may be available, but long-term supply cannot be guaranteed. The substitute part (SPMWHT541MP5WAWMS4) carries "Active" status, ensuring continued manufacturing and supply chain support.

Q: Are there thermal performance differences between these components?

A: The substitute part exhibits lower thermal resistance (15°C/W vs. 16°C/W), indicating marginally improved heat dissipation. This difference is minor and does not typically affect circuit design decisions. Both components are suitable for standard LED lighting applications within their specified current ranges.

Q: How do the electrical specifications compare at the 65mA test current?

A: At 65mA test current, forward voltage differs by 0.05V (2.9V main vs. 2.95V substitute). The substitute provides documented luminous output (31 lm) and efficiency (162 lm/W), whereas the main part does not specify these parameters. Both components operate within acceptable ranges for warm white LED applications.

Q: What packaging and handling precautions apply to both components?

A: Both components carry MSL rating 2A (4 Weeks), requiring storage at controlled humidity (≤30% RH) and temperature (≤25°C) for maximum shelf life. Moisture sensitivity level 2A permits up to 4 weeks of exposure before reflow soldering. Baking procedures may be required if storage limits are exceeded.

Q: Does the 0.6mm length difference affect PCB layout?

A: The substitute part measures 5.60mm in length versus 5.00mm for the main part. Verify that your PCB footprint and surrounding component placement accommodate this increase. The height reduction (0.80mm vs. 0.90mm) provides additional assembly clearance. Consult your PCB design files and assembly documentation to confirm spatial compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both SPMWHT541MD5WAWMS1 and SPMWHT541MP5WAWMS4 are RoHS Compliant, meeting EU Directive 2011/65/EU requirements. ECCN and HTSUS classifications are identical, supporting equivalent regulatory treatment.
