• Color specification (White, Cool)
• CCT value (5000K)
• Forward voltage (2.75V typical)
• Test current (65mA)
• Luminous flux range (37lm–39lm @ 25°C)
• CRI rating (80)
• Maximum current rating (200mA)

Mechanical Equivalence Criteria:

• Package type (4-SMD, Flat Leads)
• Supplier device package (5630)
• Physical dimensions (5.00mm x 3.00mm)
• Maximum seated height (0.80mm)
• Thermal resistance (12°C/W)
• Mounting type (Surface Mount)

Compliance Equivalence Criteria:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant)
• Moisture sensitivity level (2A, 4 Weeks)
• ECCN classification (EAR99)
• HTSUS code (8541.41.0000)

The substitute part SPMWHT541ML5XAR0S6 meets all electrical, mechanical, and compliance requirements for direct substitution in applications designed for SPMWHT541ML5XARMS6.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XARMS6 and SPMWHT541ML5XAR0S6 are Active product status components manufactured by Samsung Semiconductor, Inc., and are suitable for current production designs.

Compliance Considerations:

• SPMWHT541ML5XARMS6 carries RoHS Compliant certification
• SPMWHT541ML5XAR0S6 carries ROHS3 Compliant certification

Both certifications satisfy RoHS requirements. ROHS3 represents an updated compliance designation and may be preferred for applications requiring the latest regulatory alignment.

Electrical Performance: The lumens/watt efficiency differs by 1 lm/W (213 lm/W versus 212 lm/W), which falls within normal manufacturing tolerance for LED components and does not constitute a functional difference for circuit design purposes.

Inventory and Availability:

• SPMWHT541ML5XARMS6: 952 Pcs in stock
• SPMWHT541ML5XAR0S6: 1054 Pcs in stock

Both parts are available in Tape & Reel packaging suitable for automated assembly processes.

Selection Basis: Component selection should be based on supply chain availability, compliance certification requirements for the end application, and inventory status at the time of procurement. Both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAR0S6 be used as a direct replacement for SPMWHT541ML5XARMS6 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical electrical specifications (2.75V forward voltage, 65mA test current, 38lm luminous flux, 5000K CCT, 80 CRI), identical package dimensions (5630, 5.00mm x 3.00mm), and identical mounting characteristics (4-SMD, Flat Leads, Surface Mount). No circuit redesign is required.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent regulatory update. For applications requiring current regulatory alignment, ROHS3 Compliant parts are preferred. Both certifications satisfy RoHS requirements for component selection.

Q: Are the thermal characteristics identical between these two parts?

A: Yes. Both parts have a thermal resistance of 12°C/W, identical maximum seated height of 0.80mm, and identical package construction. Thermal performance in circuit applications will be equivalent.

Q: What is the significance of the 1 lm/W difference in lumens/watt efficiency?

A: The difference between 213 lm/W and 212 lm/W represents a 0.47% variation and falls within normal manufacturing tolerance for LED components. This difference does not affect circuit design, power calculations, or functional performance in practical applications.

Q: Are both parts suitable for automated assembly?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging with identical 5630 package specifications, flat leads, and 4-SMD configuration. They are compatible with standard surface mount assembly equipment and processes.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts carry MSL 2A rating with a 4-week floor life. This indicates moderate moisture sensitivity. Components must be stored in dry conditions and used within 4 weeks of bag opening. Standard moisture-controlled storage and handling procedures apply.

Q: Can these parts be used interchangeably in mid-production if supply constraints occur?

A: Yes. The electrical, mechanical, and compliance equivalence between SPMWHT541ML5XARMS6 and SPMWHT541ML5XAR0S6 permits interchangeable use without design modification, process change, or performance impact. Both parts are from the same manufacturer and series.
