SPMWHT541MP5WATSS5 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WATSS5 is a Samsung Semiconductor LM561B Plus white neutral LED in 5630 surface mount package. This component is an active product designed for LED lighting applications requiring neutral white color temperature at 4000K with high luminous efficacy. The part is available in tape and reel packaging for automated assembly processes.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design revisions require alternative manufacturing batches while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for SPMWHT541MP5WATSS5 is determined by strict parametric equivalence across the following critical parameters:

• Color and CCT: White, Neutral 4000K (exact match required)
• Luminous flux at test current: 35lm nominal (34-36lm range)
• Forward voltage: 2.95V typical
• Test current: 65mA
• Maximum current rating: 180mA
• CRI: 80
• Viewing angle: 120°
• Package type: 4-SMD, Flat Leads 5630
• Physical dimensions: 5.00mm x 3.00mm, 0.80mm height
• Mounting: Surface Mount
• Packaging format: Tape & Reel

All three substitute part numbers meet these parametric requirements and are manufactured by Samsung Semiconductor, Inc. Variations in product status, thermal resistance tolerance (±1°C/W), RoHS certification revision level, and moisture sensitivity level do not affect functional interchangeability in the specified application.

Parameter Comparison

Engineering Selection Recommendations

All three substitute part numbers are parametrically equivalent to SPMWHT541MP5WATSS5 and are suitable for direct replacement in existing designs.

SPMWHT541MP5WAT0S5 and SPMWHT541MP5WATMS5 are both active products with current manufacturing status, making them preferred choices for new production orders and long-term supply continuity.

SPMWHT541MP5WATUS5 carries a "Not For New Designs" status, indicating Samsung has transitioned this part number to legacy support. While functionally equivalent and currently in stock, this part number should not be selected for new design implementations. It remains suitable only for sustaining production of existing designs or repair applications where the original part number must be maintained.

Thermal resistance variation between the main part (14°C/W) and substitute parts (15°C/W) falls within acceptable manufacturing tolerance and does not affect thermal performance in standard LED lighting applications.

RoHS compliance status differs between parts (ROHS3 versus RoHS Compliant), reflecting different certification dates. Both certifications meet current regulatory requirements for electronic component manufacturing.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATUS5 be used in new product designs?

A: No. SPMWHT541MP5WATUS5 is marked "Not For New Designs" by Samsung. Use SPMWHT541MP5WAT0S5 or SPMWHT541MP5WATMS5 for new designs to ensure long-term supply availability and manufacturer support.

Q: What is the difference between SPMWHT541MP5WAT0S5 and SPMWHT541MP5WATMS5?

A: Both parts are parametrically identical and active products. The difference in part number suffix reflects different manufacturing batches or packaging configurations. Both are suitable for production use.

Q: Is the 1°C/W thermal resistance difference between SPMWHT541MP5WATSS5 and the substitutes significant?

A: No. The thermal resistance variation (14°C/W versus 15°C/W) is within normal manufacturing tolerance and does not affect thermal performance in standard LED lighting applications. Thermal design calculations should account for this minor variation only in extreme thermal environments.

Q: Are all substitute parts available in the same tape and reel packaging?

A: Yes. All parts are supplied in Tape & Reel (TR) packaging format suitable for automated pick-and-place assembly. Physical dimensions, lead configuration, and reel specifications are identical across all part numbers.

Q: Can I mix different part numbers in the same production batch?

A: Yes. All parts are parametrically equivalent and interchangeable. However, for traceability and quality control purposes, maintaining consistent part numbers within a single production batch is recommended.

Q: What does the RoHS compliance difference mean?

A: ROHS3 and RoHS Compliant both indicate full compliance with Restriction of Hazardous Substances regulations. The designation difference reflects the certification date and revision level of the standard at the time of manufacture. Both are equally compliant with current regulatory requirements.
