Parameter Comparison

Engineering Selection Recommendations

SPMWHT541ML7XAP0S0 (Parametric Equivalent): This part is the direct parametric equivalent to the main part number. It maintains identical electrical specifications (2.75V Vf, 29lm flux, 200mA max current) and thermal characteristics (12°C/W). The primary distinction is Active product status versus Not For New Designs. This part is suitable for direct replacement in existing designs and provides the highest inventory availability (1030 pcs). Both parts are RoHS compliant with identical MSL ratings and package specifications.

SPMWHT541MP7WAP0S0 (Functional Substitute): This LM561B Plus variant maintains color temperature (6500K), CRI (90), package format (5630), and viewing angle (120°) compatibility. The forward voltage increases to 2.95V (0.20V higher), and flux output decreases to 27lm (within acceptable variation). Maximum current rating is 180mA (20mA lower). Thermal resistance increases to 15°C/W (3°C/W higher). This part is suitable for applications where the slightly higher forward voltage and lower maximum current rating do not conflict with circuit design parameters. Active product status supports long-term availability.

Both substitute parts maintain full mechanical and optical compatibility with the original design while offering improved product lifecycle status and adequate inventory levels.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAP0S0 be used as a direct replacement for SPMWHT541ML7XAPNS0?

A: Yes. Both parts are LM561C series with identical electrical specifications (2.75V Vf, 29lm flux, 200mA max current), thermal resistance (12°C/W), and package format (5630 4-SMD). The primary difference is product status: the equivalent part is Active while the original is Not For New Designs. Mechanical and optical parameters are identical.

Q: What are the limitations of using SPMWHT541MP7WAP0S0 as a substitute?

A: The LM561B Plus variant introduces three parameter changes: forward voltage increases from 2.75V to 2.95V, flux output decreases from 29lm to 27lm, and maximum current rating decreases from 200mA to 180mA. Thermal resistance also increases from 12°C/W to 15°C/W. These changes are within acceptable engineering tolerances for most applications but must be verified against specific circuit design requirements, particularly if the original design operates near maximum current or thermal limits.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All three parts use identical 5630 package format with 4-SMD flat leads, matching dimensions of 5.00mm × 3.00mm × 0.80mm maximum height. PCB footprints and reflow profiles are compatible without modification.

Q: Do the substitute parts maintain the same environmental compliance?

A: Yes. All parts are RoHS compliant with MSL rating 2A (4 Weeks). ECCN and HTSUS classifications are identical across all three parts.

Q: Which substitute part should be selected for new designs?

A: SPMWHT541ML7XAP0S0 is recommended for new designs. It maintains identical specifications to the original part while offering Active product status, ensuring long-term availability and supply chain stability. SPMWHT541MP7WAP0S0 is suitable only if circuit design parameters accommodate the 0.20V higher forward voltage and 20mA lower maximum current rating.

Q: What is the inventory status for each part?

A: SPMWHT541ML7XAP0S0 has 1030 pcs available, SPMWHT541MP7WAP0S0 has 748 pcs available, and SPMWHT541ML7XAPNS0 has 671 pcs available. The equivalent part offers the highest stock level.
