SPMWHT541MP7WAQKS0 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP7WAQKS0 is an LED lighting component from Samsung Semiconductor's LM561B Plus series, classified as a white, cool-toned LED with a correlated color temperature (CCT) of 5700K. This surface-mount device operates at 2.95V forward voltage with a test current of 65mA and delivers 28 lumens at 25°C. The component is actively produced and maintains RoHS compliance status. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and thermal characteristics align within the specified parameter ranges, enabling direct replacement in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP7WAQKS0 are identified based on strict electrical and mechanical parameter alignment within the LM561B Plus series. The substitution logic is governed by the following criteria:

Electrical Compatibility Parameters:

• Forward voltage (Vf) must remain 2.95V typical
• Test current must be 65mA
• Maximum current rating must be 180mA
• Lumens/Watt efficiency must be 146 lm/W
• CRI must be 90
• Flux output at 25°C must fall within the 25–31 lm range

Mechanical Compatibility Parameters:

• Package type: 4-SMD, Flat Leads (5630 supplier device package)
• Dimensions: 5.00mm × 3.00mm
• Maximum seated height: 0.80mm
• Thermal resistance: 15°C/W
• Mounting type: Surface Mount

Allowed Variation:

• CCT (Correlated Color Temperature) may vary within the white, cool spectrum (5000K–5700K range) without affecting electrical or mechanical substitution eligibility, as this parameter affects perceived color only and does not impact circuit-level compatibility or physical fit.

Compliance Parameters:

• Product status must be Active
• RoHS compliance required (RoHS Compliant or ROHS3 Compliant acceptable)
• MSL rating must be 2A (4 Weeks) or equivalent

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WARMS0 is a direct electrical and mechanical substitute for the SPMWHT541MP7WAQKS0. Both components share identical electrical specifications, package geometry, thermal characteristics, and compliance certifications. The sole difference is the correlated color temperature: the main part operates at 5700K while the substitute operates at 5000K. Both fall within the white, cool spectrum and do not affect circuit-level compatibility or physical fit.

Selection Basis:

1. Electrical Equivalence: Forward voltage, test current, maximum current, efficiency (lm/W), and CRI are identical across both parts.

2. Mechanical Compatibility: Both components use the 5630 package format with 4-SMD flat leads, identical dimensions (5.00mm × 3.00mm), and maximum seated height of 0.80mm. PCB footprints and reflow profiles are interchangeable.

3. Thermal Performance: Thermal resistance of 15°C/W is identical, ensuring equivalent thermal management in circuit applications.

4. Compliance Status: Both parts maintain active product status and RoHS compliance. The substitute carries ROHS3 certification, which supersedes RoHS Compliant status and indicates compliance with the most current regulatory requirements.

5. Moisture Sensitivity: Both parts carry MSL 2A (4 Weeks) rating, requiring identical handling and storage protocols.

Application Consideration: The CCT difference (5700K vs. 5000K) affects only the perceived color temperature of emitted light. Applications requiring a specific color temperature should account for this difference. In applications where color temperature is not a critical parameter, the substitute provides full functional equivalence.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP7WARMS0 be used as a direct replacement for SPMWHT541MP7WAQKS0 on the same PCB?

A: Yes. Both components share identical electrical specifications (2.95V Vf, 65mA test current, 180mA max current), package geometry (5630, 4-SMD flat leads), and thermal characteristics (15°C/W). PCB footprints and reflow profiles are interchangeable without design modification.

Q2: What is the difference between the main part and the substitute?

A: The primary difference is correlated color temperature (CCT). The main part (SPMWHT541MP7WAQKS0) operates at 5700K, while the substitute (SPMWHT541MP7WARMS0) operates at 5000K. Both are classified as white, cool-toned LEDs. All other electrical, mechanical, and thermal parameters are identical.

Q3: Does the CCT difference affect circuit performance?

A: No. CCT affects only the perceived color of emitted light and does not impact electrical performance, forward voltage, current draw, efficiency, or thermal behavior. Circuit-level compatibility is unaffected.

Q4: Are both parts RoHS compliant?

A: Yes. The main part carries RoHS Compliant certification, while the substitute carries ROHS3 Compliant certification. ROHS3 represents compliance with the most current RoHS directive requirements and is fully acceptable for applications requiring RoHS compliance.

Q5: What is the MSL rating, and does it differ between the two parts?

A: Both parts carry MSL 2A (4 Weeks), indicating identical moisture sensitivity levels. Both require storage in controlled humidity environments and must be used within 4 weeks of bag opening under standard conditions (23°C, 50% RH).

Q6: Can I mix these parts in the same production batch?

A: Yes, from an electrical and mechanical standpoint. However, if color temperature consistency is required for the final product, parts should not be mixed, as the 700K difference (5700K vs. 5000K) may be perceptible in side-by-side comparison. For applications where color temperature uniformity is not critical, mixing is acceptable.

Q7: What is the thermal resistance specification, and why is it important?

A: Both parts have a thermal resistance of 15°C/W. This parameter indicates how effectively the LED package dissipates heat to the PCB. Identical thermal resistance ensures equivalent thermal performance and allows the substitute to operate within the same temperature range as the main part.

Q8: Are there any inventory or lead time advantages to using the substitute?

A: Inventory levels are provided for reference only and do not constitute a selection criterion. Part selection should be based on electrical, mechanical, and compliance parameters. Inventory availability may vary by supplier and time of inquiry.
