Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAWSS5 are identified based on strict electrical and mechanical parameter matching within the LM561B Plus series. The substitution criteria are:

Critical Parameters for Substitution:

• Color: White, Warm (2700K CCT)
• Flux output: 33lm at 65mA test current
• Forward voltage: 2.95V typical
• Current rating: 65mA test, 180mA maximum
• Lumens/Watt efficiency: 172 lm/W
• CRI: 80
• Viewing angle: 120°
• Package: 4-SMD, Flat Leads (5630)
• Physical dimensions: 5.00mm x 3.00mm, 0.80mm height
• Mounting type: Surface Mount

The identified substitutes (SPMWHT541MP5WAWMS5 and SPMWHT541MP5WAWUS5) maintain identical electrical performance and mechanical compatibility. Variations in thermal resistance (15°C/W vs. 14°C/W) and product status do not affect functional interchangeability in standard applications. Packaging designation differences (SS5, MS5, US5) indicate regional or supplier-specific tape and reel configurations with no impact on component performance.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAWMS5 is the primary substitute for new designs and production applications. This part maintains Active product status, ROHS3 compliance, and identical electrical specifications. Thermal resistance is 15°C/W compared to 14°C/W in the original part; this 1°C/W difference is negligible in standard thermal management scenarios and does not affect component functionality. Inventory availability (23,477 pcs) supports sustained production requirements.

SPMWHT541MP5WAWUS5 is classified as Not For New Designs and carries legacy product status. While electrical and mechanical parameters are identical to the main part, this designation indicates Samsung has discontinued active development and support for this variant. Use of this part is restricted to sustaining existing production or legacy system maintenance only. RoHS compliance status differs (RoHS Compliant vs. ROHS3 Compliant), reflecting older regulatory certification. Inventory availability (14,012 pcs) is lower than the primary substitute.

For new design implementations, SPMWHT541MP5WAWMS5 is the recommended selection. For existing designs currently using SPMWHT541MP5WAWSS5, either substitute provides functional equivalence with no circuit redesign required.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS5 be used as a direct replacement for SPMWHT541MP5WAWSS5?

A: Yes. Both parts are electrically and mechanically identical. They share the same forward voltage (2.95V), test current (65mA), maximum current (180mA), luminous flux (33lm), color temperature (2700K), CRI (80), viewing angle (120°), and package dimensions (5.00mm x 3.00mm x 0.80mm). The thermal resistance difference (15°C/W vs. 14°C/W) does not affect interchangeability in standard applications.

Q: What is the difference between the SS5, MS5, and US5 packaging designations?

A: These designations indicate regional or supplier-specific tape and reel configurations. SS5, MS5, and US5 refer to different tape and reel specifications for the same 5630 package. The component itself is identical; only the packaging format differs. Selection depends on your assembly equipment compatibility and regional supply chain requirements.

Q: Why is SPMWHT541MP5WAWUS5 marked as Not For New Designs?

A: This designation indicates Samsung has transitioned this part to legacy status and no longer actively supports new design implementations. While the part remains functionally equivalent, Samsung recommends using SPMWHT541MP5WAWMS5 for new projects to ensure long-term supply continuity and access to current technical support.

Q: Are there any thermal management differences between these substitutes?

A: The main part (SPMWHT541MP5WAWSS5) has a thermal resistance of 14°C/W, while both substitutes have 15°C/W. This 1°C/W difference is within normal manufacturing tolerance and does not require circuit redesign. Thermal performance remains equivalent for standard operating conditions.

Q: Can these parts be used interchangeably in existing PCB designs without modification?

A: Yes. All three parts share identical package dimensions (5.00mm x 3.00mm), height (0.80mm), lead configuration (4-SMD, Flat Leads), and mounting type (Surface Mount). No PCB layout changes are required for substitution.

Q: What compliance certifications apply to each part?

A: SPMWHT541MP5WAWSS5 and SPMWHT541MP5WAWMS5 are ROHS3 Compliant. SPMWHT541MP5WAWUS5 is RoHS Compliant (earlier standard). All three parts are REACH Unaffected or REACH Compliant and classified under ECCN EAR99 with HTSUS code 8541.41.0000.
