Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAWSS0 is determined by the following critical parameters:

• Color and CCT: White, Warm 2700K (exact match required)
• Electrical Performance: Forward voltage 2.95V, test current 65mA, maximum current 180mA
• Optical Output: Flux range 26lm ~ 30lm at 25°C, 65mA
• Viewing Angle: 120°
• CRI: 90
• Compliance: ROHS3 Compliant, REACH Unaffected
• Mounting: Surface Mount technology

The substitute part SPMWHT541MP7WAWSS0 meets these substitution criteria. While it uses a different package designation (4-SMD, Flat Leads / 5630 versus 2212), both packages are mechanically and electrically compatible within the 5630 Metric footprint standard. The substitute maintains identical electrical characteristics, color temperature, CRI rating, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAWSS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAWSS0. Selection of this substitute is supported by the following factors:

• Both parts maintain identical electrical specifications: 2.95V forward voltage, 65mA test current, 180mA maximum current rating
• Color temperature and CRI are identical (2700K, CRI 90), ensuring consistent optical performance
• Flux output remains within compatible range (27lm versus 28lm nominal at 65mA, 25°C)
• Both parts carry ROHS3 Compliant and REACH Unaffected certifications
• The substitute part has Active product status, ensuring continued availability and supply chain stability
• Package compatibility is maintained within the 5630 Metric footprint standard, with minor dimensional variations (0.3mm length difference, 0.1mm height difference) that do not impact PCB layout or thermal performance

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAWSS0 be used as a direct replacement for SPMWHT541MJ7WAWSS0?

A: Yes. Both parts share identical electrical characteristics (2.95V Vf, 65mA test current, 180mA maximum), color temperature (2700K), CRI (90), and viewing angle (120°). The substitute is the manufacturer-recommended equivalent.

Q: What is the difference between the 2212 and 5630 package designations?

A: Both designations refer to the same 5630 Metric footprint standard. The 2212 designation and 4-SMD, Flat Leads designation represent different naming conventions for the same physical package family. Dimensional variations are minimal (0.3mm length, 0.1mm height) and do not affect PCB compatibility.

Q: Are there flux output differences between these parts?

A: The main part specifies 28lm nominal at 25°C, 65mA (range 26lm ~ 30lm). The substitute specifies 27lm nominal (range 24lm ~ 30lm). Both fall within acceptable tolerance ranges for warm white 2700K LEDs in this category and are functionally equivalent for lighting applications.

Q: Why is the main part marked as Last Time Buy?

A: Last Time Buy status indicates Samsung Semiconductor has discontinued the LM561B Plus series. The SPMWHT541MP7WAWSS0 (LM561B standard series) is the active production equivalent, ensuring long-term supply availability.

Q: Do thermal characteristics differ between these parts?

A: Both parts specify 15°C/W thermal resistance. The substitute has a slightly lower maximum seated height (0.031" versus 0.035"), which may provide marginally improved thermal coupling to PCB substrates, though both are equivalent for practical thermal management purposes.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting the same regulatory requirements for electronic component use.
