Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XAVUS6 is determined by strict equivalence across the following parameters:

• Series Match: Both parts must belong to the LM561C series
• Color and CCT: Identical warm white 3000K specification
• Electrical Performance: Matching forward voltage (2.75V typical), test current (65mA), and luminous flux output (36lm at 25°C)
• Mechanical Compatibility: Identical 4-SMD flat lead package in 5630 form factor with matching dimensions and thermal characteristics
• Regulatory Compliance: Both parts must maintain ROHS3 and REACH compliance status
• Product Status: Active production status required for both main and substitute parts

The substitute part SPMWHT541ML5XAVMS6 meets all these criteria as a parametric equivalent within the same product series and packaging specification.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XAVUS6 and SPMWHT541ML5XAVMS6 are functionally equivalent components suitable for direct substitution in applications requiring LM561C warm white 3000K LEDs. Selection between these parts may be based on inventory availability and supply chain considerations. The SPMWHT541ML5XAVMS6 maintains significantly higher inventory levels (202,652 pieces versus 1,003 pieces), which may provide supply chain advantages for high-volume production requirements. Both parts carry identical regulatory compliance certifications (ROHS3 and REACH) and maintain active production status, ensuring long-term component availability and support.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAVMS6 be used as a direct replacement for SPMWHT541ML5XAVUS6?

A: Yes. Both parts are parametric equivalents within the LM561C series with identical electrical specifications, optical performance, mechanical dimensions, and regulatory compliance. Direct substitution is supported without circuit or layout modifications.

Q: Are there differences in thermal performance between these parts?

A: No. Both parts specify identical thermal resistance of 12°C/W, ensuring equivalent thermal behavior in circuit applications.

Q: What is the significance of the different part number suffixes (US6 versus MS6)?

A: The suffix designations reflect different manufacturing or distribution batches within the same product specification. The electrical and mechanical parameters remain identical across both variants.

Q: Is moisture sensitivity level specified for the main part?

A: Moisture sensitivity level (MSL) is specified for SPMWHT541ML5XAVMS6 as 2A (4 Weeks). This parameter was not provided for SPMWHT541ML5XAVUS6 in the available documentation.

Q: Can these LEDs be operated at currents other than 65mA?

A: Yes. Both parts support operation up to a maximum current of 200mA. However, the specified luminous flux of 36 lumens is measured at the 65mA test current. Operation at different currents will produce different light output levels.

Q: Are these parts suitable for high-temperature applications?

A: Thermal resistance is specified at 12°C/W for both parts. Thermal performance in specific applications depends on PCB design, thermal management implementation, and ambient operating conditions. Detailed thermal analysis is required for high-temperature environments.
