Substitute Part Grouping Explanation

The SPMWHT541MP5WAQSS4 has one identified parametric equivalent: SPMWHT541MP5WAQKS4. Both components share identical electrical and optical specifications, including color temperature (5700K), luminous flux (34lm at 25°C), forward voltage (2.95V), test current (65mA), maximum current (180mA), viewing angle (120°), and CRI (80). Both are packaged as 4-SMD flat leads in the 5630 form factor with identical physical dimensions (5.00mm x 3.00mm x 0.80mm maximum height). Both maintain ROHS3 compliance and REACH unaffected status. The substitution is based on matching all critical electrical parameters, optical output characteristics, mechanical form factor, and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541MP5WAQSS4 and SPMWHT541MP5WAQKS4 are active products from Samsung Semiconductor with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and procurement requirements. The SPMWHT541MP5WAQKS4 carries a Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), which defines handling and storage requirements for moisture-sensitive components. Both parts are electrically and mechanically interchangeable for applications requiring 5700K cool white LEDs in the 5630 surface mount package with 120° viewing angle and 80 CRI performance.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541MP5WAQSS4 and SPMWHT541MP5WAQKS4 directly interchangeable?

A: Yes. Both components share identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical output (34 lumens at 25°C, 177 lm/W efficacy, 5700K color temperature, 80 CRI), mechanical form factor (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm x 0.80mm), and regulatory compliance (ROHS3, REACH unaffected). They are direct parametric equivalents.

Q: What is the significance of the MSL rating on SPMWHT541MP5WAQKS4?

A: The MSL 2A (4 Weeks) rating indicates the component can be exposed to ambient conditions of 30°C and 60% relative humidity for up to 4 weeks before soldering. This affects storage, handling, and shelf-life management but does not impact electrical or optical performance.

Q: Can these LEDs be operated above the 65mA test current?

A: The maximum rated current is 180mA. Operation above the test current of 65mA will increase luminous output and power consumption but may affect thermal characteristics and component lifespan. Thermal management and circuit design must account for the thermal resistance of 14°C/W (SPMWHT541MP5WAQSS4) or 15°C/W (SPMWHT541MP5WAQKS4).

Q: Are there any differences in thermal performance between the two parts?

A: The thermal resistance differs slightly: SPMWHT541MP5WAQSS4 has 14°C/W while SPMWHT541MP5WAQKS4 has 15°C/W. This minor difference does not affect substitution eligibility for standard applications.

Q: What applications are these LEDs suitable for?

A: These components are designed for general illumination applications requiring cool white light at 5700K color temperature with high color rendering (CRI 80). The 120° viewing angle and surface mount package make them suitable for integrated lighting modules, display backlighting, and accent lighting systems.
