Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML5XATUS5 are identified based on strict parametric equivalence within the LM561C series. All substitute parts maintain identical electrical and optical specifications: 4000K neutral white color temperature, 35 lumens output at 65mA test current, 2.75V forward voltage, 196 lm/W efficiency, 80 CRI, and 120° viewing angle. All parts share the same 5630 surface mount package with 4-SMD flat leads configuration, identical 5.00mm x 3.00mm dimensions, and 0.80mm maximum seated height.

The substitution logic is based on the following key parameters that determine interchangeability:

• Color and CCT specification (White, Neutral 4000K)
• Optical output (35lm at 65mA)
• Electrical characteristics (2.75V Vf, 65mA test current, 200mA max)
• Package and mounting type (5630, 4-SMD, Surface Mount)
• Physical dimensions and thermal properties
• Compliance certifications (ROHS3, EAR99, HTSUS classification)

Differences in packaging codes (ATUS5, AT0S5, ATMS5) and moisture sensitivity level designations reflect distribution channel variants and storage condition classifications, not functional differences.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are active production components from Samsung Semiconductor with ROHS3 compliance and identical electrical, optical, and mechanical specifications. Selection between SPMWHT541ML5XATUS5, SPMWHT541ML5XAT0S5, and SPMWHT541ML5XATMS5 is determined by inventory availability and supply chain requirements rather than functional performance differences.

SPMWHT541ML5XATMS5 offers the highest inventory level at 25846 pieces, followed by SPMWHT541ML5XAT0S5 with 14120 pieces. SPMWHT541ML5XATUS5 maintains 1105 pieces in stock. The moisture sensitivity level designation of 2A (4 Weeks) specified for the AT0S5 and ATMS5 variants indicates standard handling and storage conditions for surface mount components. All parts carry identical EAR99 export classification and HTSUS code 8541.41.0000.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541ML5XATUS5, SPMWHT541ML5XAT0S5, and SPMWHT541ML5XATMS5 functionally identical?

A: Yes. All three part numbers are parametrically equivalent LM561C series LEDs with identical electrical output (2.75V, 65mA), optical performance (35 lumens, 4000K, 80 CRI), and mechanical specifications (5630 package, 5.00mm x 3.00mm, 0.80mm height). Differences in part number suffixes reflect packaging channel and moisture sensitivity classifications, not performance variations.

Q: What do the different packaging codes (ATUS5, AT0S5, ATMS5) represent?

A: The packaging code variants indicate different distribution channels and moisture sensitivity level designations. ATUS5 does not specify MSL in the provided data. AT0S5 and ATMS5 are designated as MSL 2A (4 Weeks), representing standard moisture sensitivity for surface mount components. All variants use identical Tape & Reel (TR) packaging format.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts share the same 4-SMD flat leads configuration in 5630 package format with identical 5.00mm x 3.00mm footprint and 0.80mm maximum height. PCB layouts, solder profiles, and assembly processes require no modification when substituting between these part numbers.

Q: What is the thermal resistance specification and how does it affect circuit design?

A: The thermal resistance of 12°C/W indicates the temperature rise per watt of power dissipation. At the 65mA test current with 2.75V forward voltage, power dissipation is approximately 0.179W, resulting in a junction temperature rise of approximately 2.1°C above ambient. This specification is identical across all three substitute parts.

Q: Are there any compliance or certification differences between the three part numbers?

A: All three parts are ROHS3 compliant with EAR99 export classification and HTSUS code 8541.41.0000. SPMWHT541ML5XATUS5 specifies REACH Unaffected status. The AT0S5 and ATMS5 variants include explicit MSL 2A (4 Weeks) moisture sensitivity designation. These differences do not affect functional compatibility or electrical performance.
