Engineering Selection Recommendations

Both the SPMWHT541ML5XAWSS0 and SPMWHT541ML5XAWMS0 are Active status products manufactured by Samsung Semiconductor, Inc., and maintain ROHS3 compliance. The substitute part SPMWHT541ML5XAWMS0 exhibits a forward voltage increase of 0.05V and a maximum current reduction of 20 mA compared to the main part. These variations remain within acceptable engineering tolerances for the LM561C series 5630 package LED.

Selection between these parts should be based on circuit design requirements. The SPMWHT541ML5XAWSS0 supports higher maximum current operation (200 mA vs. 180 mA), while the SPMWHT541ML5XAWMS0 offers greater inventory availability (31,957 pcs vs. 1,014 pcs). Both parts deliver equivalent luminous flux and color temperature performance within the specified 30–34 lm range at 2700K.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS0 be used as a direct replacement for SPMWHT541ML5XAWSS0?

A: Yes. Both parts are LM561C series warm white LEDs in 5630 package configuration with identical color temperature (2700K), luminous flux (32 lm), viewing angle (120°), and physical dimensions (5.00 × 3.00 mm). The forward voltage difference of 0.05V and maximum current difference of 20 mA are within acceptable engineering tolerances for most lighting applications.

Q: What is the significance of the forward voltage difference?

A: The SPMWHT541ML5XAWMS0 operates at 2.8V typical forward voltage compared to 2.75V for the SPMWHT541ML5XAWSS0. This 0.05V increase requires verification in current-limiting circuit designs to ensure proper current regulation and thermal management. Recalculation of series resistor values may be necessary in constant-voltage supply configurations.

Q: Are there package or mounting differences between these parts?

A: No. Both parts use identical 4-SMD flat lead package configuration in 5630 supplier device package format. Physical dimensions (5.00 × 3.00 mm), maximum seated height (0.80 mm), and thermal resistance (12°C/W) are identical. Surface mount assembly processes require no modification.

Q: What is the impact of the maximum current difference?

A: The SPMWHT541ML5XAWMS0 has a maximum current rating of 180 mA versus 200 mA for the SPMWHT541ML5XAWSS0. Applications operating at or near 200 mA must verify that the substitute part's 180 mA maximum rating is sufficient. Test current for both parts remains 65 mA with identical luminous flux output.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both SPMWHT541ML5XAWSS0 and SPMWHT541ML5XAWMS0 are ROHS3 compliant and REACH unaffected. ECCN classification (EAR99) and HTSUS code (8541.41.0000) are identical for both parts.

Q: Which part should be selected for new designs?

A: Selection depends on circuit requirements and supply chain considerations. The SPMWHT541ML5XAWMS0 offers significantly higher inventory availability (31,957 pcs). The SPMWHT541ML5XAWSS0 supports higher maximum current operation. Both deliver equivalent optical and thermal performance within specified parameters.
