The substitute part SPMWHT541MP7WAVSS0 meets all electrical and mechanical criteria, with minor variations in flux output and package designation that remain within functional equivalence for standard lighting applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP7WAVSS0

This part is the manufacturer-recommended substitute. Both components are Samsung Semiconductor products within the LM561B family, maintaining identical electrical specifications for forward voltage, test current, maximum current, CRI, and viewing angle. The substitute carries Active product status, ensuring ongoing availability and supply chain stability compared to the Last Time Buy status of the main part.

Flux output differs marginally (28 lm versus 29 lm at 65mA), representing a 3.4% reduction in luminous intensity. This variance falls within the specified tolerance ranges (25–31 lm for the substitute, 27–31 lm for the main part) and does not constitute a functional incompatibility for standard lighting applications.

Physical dimensions show minor reductions: length decreases from 5.30mm to 5.00mm, and height from 0.90mm to 0.80mm. Both components maintain the 5630 metric footprint classification and are compatible with standard surface-mount assembly processes. The package designation change from 2212 to 4-SMD, Flat Leads reflects internal lead configuration differences that do not affect PCB-level compatibility.

Both parts maintain ROHS3 compliance and identical thermal resistance ratings (15°C/W), supporting equivalent thermal management in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVSS0 be used as a direct replacement for SPMWHT541MJ7WAVSS0?

A: Yes. Both components share identical electrical specifications at the operating point (2.95V, 65mA, 3000K, 90 CRI, 120° viewing angle). The substitute is the manufacturer-recommended equivalent and maintains compatibility with existing PCB designs and assembly processes.

Q: What is the significance of the flux difference (29 lm vs. 28 lm)?

A: The 1 lumen difference represents a 3.4% variance and falls within the published tolerance ranges for both parts. For applications requiring specific luminous intensity, this difference should be evaluated against system-level brightness requirements, but it does not prevent functional substitution in standard lighting designs.

Q: Are the physical dimension changes (5.30mm to 5.00mm length, 0.90mm to 0.80mm height) compatible with existing PCB layouts?

A: Both components are classified as 5630 metric footprint devices and are compatible with standard surface-mount assembly equipment. The dimensional reductions represent tighter tolerances and do not create assembly or placement conflicts. PCB pad layouts designed for the 2212 package will accommodate the 4-SMD, Flat Leads configuration.

Q: Why does the main part have Last Time Buy status?

A: Last Time Buy status indicates Samsung has discontinued or will discontinue production of the SPMWHT541MJ7WAVSS0. The SPMWHT541MP7WAVSS0 carries Active status, ensuring continued availability and supply chain reliability for new production and ongoing support.

Q: Are there compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000). Thermal resistance ratings are identical at 15°C/W.

Q: What is the lumens/watt efficiency difference?

A: The main part delivers 151 lm/W while the substitute delivers 146 lm/W at 65mA test current. This 3.3% efficiency difference is consistent with the flux variance and does not indicate a functional incompatibility. Both parts operate within the same efficiency class for warm white LED lighting.
