Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML5XAT0S6 are identified based on strict electrical and mechanical parameter equivalence within the LM561C series. The substitution criteria are:

Critical Parameters for Substitution:

• Series designation (LM561C)
• Color specification (White, Neutral)
• Correlated Color Temperature (4000K)
• Luminous flux range at test current (36lm ~ 38lm @ 65mA, 25°C)
• Forward voltage (2.75V typical)
• Test current (65mA)
• Maximum current rating (200mA)
• CRI (80)
• Viewing angle (120°)
• Package type (4-SMD, Flat Leads / 5630)
• Physical dimensions (5.00mm x 3.00mm, height 0.80mm max)
• Thermal resistance (12°C/W)
• Mounting type (Surface Mount)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in RoHS certification status (RoHS Compliant vs. ROHS3 Compliant) do not preclude substitution, as both represent compliance with applicable regulations.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XAT0S6 and SPMWHT541ML5XATMS6 are Active product status components from Samsung Semiconductor's LM561C series and are suitable for direct substitution in neutral white 4000K LED applications. Selection between these parts should be based on:

Compliance Requirements: The SPMWHT541ML5XATMS6 carries ROHS3 Compliant certification, while the SPMWHT541ML5XAT0S6 is RoHS Compliant. Applications requiring ROHS3 compliance should specify SPMWHT541ML5XATMS6.

Availability: The SPMWHT541ML5XATMS6 maintains higher inventory levels (29,791 Pcs) compared to SPMWHT541ML5XAT0S6 (1,076 Pcs), making it preferable for high-volume production or extended lead-time mitigation.

Electrical and Mechanical Equivalence: All electrical parameters, mechanical dimensions, thermal characteristics, and optical properties are identical between both parts, ensuring functional interchangeability without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XATMS6 be used as a direct replacement for SPMWHT541ML5XAT0S6?

A: Yes. Both parts are parametric equivalents within the LM561C series with identical electrical specifications (2.75V forward voltage, 65mA test current, 37lm luminous flux), optical properties (4000K CCT, 80 CRI, 120° viewing angle), mechanical dimensions (5.00mm x 3.00mm, 0.80mm height), and thermal characteristics (12°C/W). No circuit modifications are required.

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

A: Both certifications indicate compliance with hazardous substance restrictions. ROHS3 represents a more recent regulatory iteration. Selection depends on application-specific compliance requirements. Both parts meet environmental and safety standards for surface-mount LED applications.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 5630 supplier device package with 4-SMD flat leads, measuring 5.00mm length x 3.00mm width with a maximum seated height of 0.80mm. PCB footprints and reflow profiles are identical.

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. Components must be stored in dry conditions and used within the specified timeframe after opening moisture-barrier packaging to prevent solder joint degradation during reflow.

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

A: Yes. Both parts are rated for operation up to 200mA maximum current. However, the specified luminous flux of 37lm is measured at the 65mA test current. Operation at different currents will produce different luminous output and thermal characteristics.

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

A: Both parts have a thermal resistance of 12°C/W. Thermal performance depends on PCB thermal design, ambient temperature, and operational current. Thermal management calculations should be performed for applications exceeding 85°C ambient or continuous high-current operation.
