SPMWHT541MP7WARKS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP7WARKS0 is an LED lighting component from Samsung Semiconductor's LM561B Plus series, designed for cool white illumination applications. This surface-mount LED operates at 5000K color temperature with a forward voltage of 2.95V and test current of 65mA, delivering 28 lumens at 25°C with a luminous efficacy of 146 lm/W. The component is housed in a 5630 package (4-SMD, Flat Leads) with a 120° viewing angle and is currently in active product status with RoHS compliance certification. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility across manufacturing batches and procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP7WARKS0 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Forward voltage (2.95V typical), test current (65mA), maximum current (180mA), and luminous output (28 lm at 25°C, 65mA) must remain identical or within the specified tolerance range (25–31 lm).

Optical Parameters: Color temperature (5000K), CRI (90), and viewing angle (120°) must match exactly to maintain consistent illumination characteristics in the target application.

Mechanical Parameters: Package type (4-SMD, Flat Leads), supplier device package designation (5630), physical dimensions (5.00mm × 3.00mm), and seated height (0.80mm maximum) must be identical to ensure PCB compatibility and assembly process alignment.

Thermal Parameters: Thermal resistance (15°C/W) must be maintained to ensure equivalent thermal performance in the application environment.

Compliance Parameters: RoHS status and MSL rating (2A, 4 Weeks) must be equivalent or superior to support the same manufacturing and storage protocols.

Product Status: Only active, in-production components qualify as substitutes to ensure long-term availability and supply chain stability.

The substitute part SPMWHT541MP7WARMS0 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541MP7WARKS0 and SPMWHT541MP7WARMS0 are active, in-production components from Samsung Semiconductor with full RoHS compliance. The substitute part SPMWHT541MP7WARMS0 carries ROHS3 certification, which represents an equivalent or enhanced compliance posture compared to the RoHS Compliant designation of the main part.

All electrical, optical, mechanical, and thermal parameters are identical between the two parts. Both components meet the same MSL rating (2A, 4 Weeks) and export classification (EAR99, HTSUS 8541.41.0000).

Selection between these parts should be based on procurement availability and supply chain logistics. The SPMWHT541MP7WARMS0 currently maintains higher inventory levels (25,904 pcs vs. 1,136 pcs), which may provide advantages for large-volume production runs or extended lead-time mitigation.

No electrical redesign, PCB layout modification, or thermal management adjustment is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541MP7WARKS0 and SPMWHT541MP7WARMS0 electrically interchangeable?

A: Yes. Both parts operate at identical forward voltage (2.95V), test current (65mA), and maximum current (180mA). They deliver the same luminous output (28 lm at 25°C, 65mA) and luminous efficacy (146 lm/W).

Q: Do these parts have the same physical footprint?

A: Yes. Both use the 5630 package (4-SMD, Flat Leads) with dimensions of 5.00mm × 3.00mm and a maximum seated height of 0.80mm. No PCB layout changes are required for substitution.

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

A: ROHS3 represents the third iteration of RoHS certification standards. Both designations indicate compliance with hazardous substance restrictions. ROHS3 Compliant status is equivalent to or more current than RoHS Compliant status.

Q: Can I use SPMWHT541MP7WARMS0 in place of SPMWHT541MP7WARKS0 without design changes?

A: Yes. All electrical, optical, mechanical, and thermal parameters are identical. Direct substitution is supported without circuit redesign or assembly process modification.

Q: Are the thermal characteristics the same?

A: Yes. Both parts have a thermal resistance of 15°C/W, ensuring equivalent thermal performance in the application environment.

Q: What is the MSL rating, and does it affect storage?

A: Both parts carry MSL 2A (4 Weeks), indicating they must be stored in controlled humidity conditions and used within 4 weeks of bag opening. Standard moisture-controlled storage protocols apply to both parts equally.

Q: Which part should I select for new designs?

A: Both parts are suitable for new designs. Selection should be based on current procurement availability and supply chain requirements. The SPMWHT541MP7WARMS0 currently has higher inventory availability.
