Substitute Part Grouping Explanation

Substitution of the SPMWHT541ML5XAWUS5 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Color (White, Warm), CCT (2700K), forward voltage (2.75V typical), test current (65mA), maximum current (200mA), and luminous flux (33 lm at 25°C, 65mA).

Optical Equivalence: CRI of 80 and viewing angle of 120°.

Mechanical Equivalence: 4-SMD flat leads package, 5630 supplier device package, dimensions of 5.00mm × 3.00mm, and maximum seated height of 0.80mm.

Thermal Equivalence: Package thermal resistance of 12°C/W.

Regulatory Equivalence: RoHS3 compliance and REACH unaffected status.

The substitute part SPMWHT541ML5XAWMS5 meets all these criteria and is therefore a direct parametric equivalent.

Engineering Selection Recommendations

Both the SPMWHT541ML5XAWUS5 and SPMWHT541ML5XAWMS5 are Active product status components manufactured by Samsung Semiconductor, Inc. Both parts are fully compliant with RoHS3 and REACH regulations, meeting current environmental and hazardous substance restrictions.

The SPMWHT541ML5XAWMS5 carries an MSL (Moisture Sensitivity Level) rating of 2A with a 4-week shelf life specification, which provides additional handling guidance for moisture-sensitive storage and assembly processes.

From an engineering perspective, both parts are electrically, optically, mechanically, and thermally equivalent. Selection between them is determined by inventory availability, packaging requirements, and moisture sensitivity handling protocols specific to the application environment.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541ML5XAWUS5 and SPMWHT541ML5XAWMS5 direct substitutes?

A: Yes. Both parts are parametric equivalents across all critical electrical, optical, mechanical, and thermal specifications. They share identical forward voltage, luminous flux, color temperature, CRI, viewing angle, package dimensions, and thermal resistance.

Q: What is the difference between these two part numbers?

A: The primary difference is the MSL (Moisture Sensitivity Level) specification. SPMWHT541ML5XAWMS5 is rated MSL 2A with a 4-week shelf life, providing explicit moisture handling requirements. Both parts are otherwise identical in performance and compliance.

Q: Can I use SPMWHT541ML5XAWMS5 in place of SPMWHT541ML5XAWUS5?

A: Yes. The parts are electrically and mechanically interchangeable. Ensure that moisture sensitivity handling procedures for MSL 2A are followed if using SPMWHT541ML5XAWMS5.

Q: What does the 5630 package designation mean?

A: 5630 is the supplier device package designation for this 4-SMD, flat leads LED. The physical dimensions are 5.00mm length × 3.00mm width × 0.80mm maximum height.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SPMWHT541ML5XAWUS5 and SPMWHT541ML5XAWMS5 are ROHS3 compliant and REACH unaffected.

Q: What is the thermal resistance specification?

A: Both parts have a thermal resistance of 12°C/W, indicating the temperature rise per watt of power dissipation in the package.

Q: Can these LEDs be operated at currents above 65mA?

A: Yes. Both parts support operation up to a maximum current of 200mA. The 65mA specification is the test current used for luminous flux and efficiency measurements.
