Parameter Comparison

Engineering Selection Recommendations

SPMWHT541ML5XAW0S0 (Primary Part): This part is the specified component with RoHS Compliant certification. It delivers 180 lm/W efficiency at 2.75V forward voltage. Selection is appropriate when the primary part number is explicitly required by design specification or when the lower forward voltage characteristic is a design constraint.

SPMWHT541ML5XAWMS0 (Substitute Part): This part is functionally equivalent with ROHS3 Compliant certification, representing enhanced regulatory compliance. The forward voltage is 2.8V (0.05V higher) and efficiency is 176 lm/W (4 lm/W lower). Both parameters remain within acceptable operating ranges for LM561C warm white 2700K applications. The substitute part is suitable for direct replacement in applications where the forward voltage tolerance and efficiency variance do not impact circuit performance or thermal management requirements. Higher inventory availability (31,957 pcs vs. 1,071 pcs) makes this substitute advantageous for supply chain continuity.

Both parts share identical package geometry, thermal characteristics, and optical properties (CRI 80, 120° viewing angle, 2700K color temperature).

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS0 be used as a direct replacement for SPMWHT541ML5XAW0S0?

A: Yes. Both parts are Samsung LM561C series warm white LEDs in 5630 package with identical optical and mechanical specifications. The forward voltage difference (2.8V vs. 2.75V) and efficiency variance (176 vs. 180 lm/W) fall within normal manufacturing tolerances for this product category and do not prevent direct substitution in standard 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 main part. This 0.05V difference requires circuit verification if the design operates near voltage supply limits or uses current-limiting resistors with tight tolerances. For most constant-current driver applications, this variance is negligible.

Q: Are there any compliance differences between these parts?

A: The main part carries RoHS Compliant certification. The substitute carries ROHS3 Compliant certification, which represents enhanced environmental and regulatory compliance. Both meet EAR99 export control and 8541.41.0000 HTSUS classifications. ROHS3 compliance is a superset of RoHS compliance and presents no compatibility issues.

Q: Do these parts have identical package dimensions?

A: Yes. Both parts are 5630 package (4-SMD, Flat Leads) with dimensions of 5.00mm length × 3.00mm width × 0.80mm maximum height. PCB footprints and reflow profiles are identical.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 2A (4 Weeks) rating. This indicates the component can be stored in dry conditions for up to 4 weeks before requiring baking prior to reflow soldering. Moisture sensitivity is identical between the main part and substitute.

Q: Is the 4 lm/W efficiency difference significant?

A: The substitute part delivers 176 lm/W versus 180 lm/W for the main part. At 65mA test current, this represents approximately 2.2% lower efficiency. For applications where luminous output is critical, verify that the 32 lm nominal flux output remains acceptable. For most general lighting applications, this variance is within acceptable performance margins.

Q: Can I mix these parts in the same production batch?

A: Both parts are from the same manufacturer and series with identical optical and mechanical properties. Mixing is permissible from a functional standpoint. However, design documentation should specify which part number is approved to maintain traceability and ensure consistency in performance characteristics across production lots.
