Engineering Selection Recommendations

SPMWHT541MP5WAWMS5 is the primary recommended substitute for SPMWHT541MP5WAW0S5. Both parts share identical electrical specifications (2.95V forward voltage, 172 lm/W efficiency, 180mA maximum current) and mechanical compatibility (5630 package, 5.00 × 3.00 mm footprint, 0.80 mm height). The SPMWHT541MP5WAWMS5 carries ROHS3 Compliant certification (versus RoHS Compliant on the main part), representing enhanced regulatory compliance. Inventory availability is significantly higher (23,477 pcs versus 741 pcs), supporting supply chain continuity. Product status is Active, confirming ongoing manufacturing support.

SPMWHT541ML5XAWMS5 is a secondary substitute suitable for applications where forward voltage reduction is acceptable. This LM561C series part operates at 2.75V (0.20V lower than the main part) while maintaining identical luminous flux (33 lm) and viewing angle (120°). The thermal resistance is improved (12°C/W versus 15°C/W), and maximum current rating is higher (200mA versus 180mA). ROHS3 Compliant status and higher inventory (1,652 pcs) support deployment. Selection of this part requires circuit validation to confirm voltage tolerance.

SPMWHT541MP5WAWUS5 is not recommended for new designs. Although electrically and mechanically identical to the main part, this variant carries "Not For New Designs" product status, indicating Samsung's discontinuation trajectory. Use only for legacy system maintenance or repair applications where part continuity is required.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS5 replace SPMWHT541MP5WAW0S5 directly?

A: Electrical substitution is valid within circuit design constraints. The 0.20V forward voltage difference (2.75V versus 2.95V) requires verification that the LED driver or current source accommodates this variation. Mechanical compatibility is confirmed (identical 5630 package, footprint, and height). Thermal performance is superior (12°C/W versus 15°C/W). Validate forward voltage tolerance in your specific circuit before deployment.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications confirm lead-free and hazardous substance restrictions. ROHS3 Compliant represents the current EU Directive 2011/65/EU standard with updated substance restrictions. RoHS Compliant indicates compliance with earlier RoHS Directive versions. Both are acceptable for most applications; ROHS3 Compliant parts provide alignment with current regulatory frameworks.

Q: Are all substitute parts identical in package and footprint?

A: Yes. All listed substitutes share the 5630 supplier device package, 4-SMD flat leads configuration, 5.00 × 3.00 mm footprint, and 0.80 mm maximum seated height. PCB layout and reflow profiles are interchangeable without modification.

Q: Why does SPMWHT541MP5WAWUS5 show "Not For New Designs" status?

A: This designation indicates Samsung's planned discontinuation of this specific part variant. Existing inventory remains available (14,012 pcs) for legacy system support and repair. New product designs should select SPMWHT541MP5WAWMS5 or SPMWHT541ML5XAWMS5 to ensure long-term supply availability and manufacturing support.

Q: What is the significance of the 33 lm flux specification?

A: The 33 lm (32–34 lm range) at 25°C and 65mA test current is the primary luminous output specification. All substitute parts maintain this specification, ensuring consistent brightness in end-use applications. This parameter is non-negotiable for substitution eligibility.

Q: Can I use SPMWHT541ML5XAWMS5 in a constant-current driver circuit?

A: Yes. Constant-current drivers maintain fixed current (65mA test condition) independent of forward voltage variation. The 0.20V difference between SPMWHT541ML5XAWMS5 (2.75V) and SPMWHT541MP5WAW0S5 (2.95V) has no impact on constant-current operation. Verify driver compliance with the lower voltage if operating near minimum supply voltage limits.

Q: What does MSL 2A (4 Weeks) mean for handling?

A: MSL (Moisture Sensitivity Level) 2A indicates the component absorbs moisture during storage and requires controlled handling. The "(4 Weeks)" specification means the part can remain at room temperature (23°C, 50% relative humidity) for up to 4 weeks after packaging before requiring bake-out prior to reflow soldering. All substitute parts share this specification, requiring identical moisture management protocols.
