Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP7WATGS0 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color: White, Neutral (4000K CCT)
• Package Type: 4-SMD, Flat Leads (5630 form factor)
• Viewing Angle: 120°
• CRI: 90
• Mounting Type: Surface Mount
• Physical Dimensions: 5.00mm × 3.00mm
• Height: 0.80mm maximum

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 2.9V to 3.0V range acceptable
• Test Current: 65mA to 150mA range
• Maximum Current: 180mA to 200mA range
• Thermal Resistance: 15°C/W to 25°C/W range

Substitute Categories:

Category 1: Direct Series Equivalent SPMWHT541MP7WATMS0 is an active production variant of the same LM561B Plus series with identical electrical and mechanical specifications except improved thermal resistance (15°C/W vs. 20°C/W) and documented luminous flux performance (27lm at 65mA, 141 lm/W).

Category 2: Parametric Equivalents SPMWH1228FD7W2T0SJ, SPMWH1228FD7W2TKSJ, SPMWH1228FD7W2TMSJ, SPMWH1228FD7WAT0SJ, SPMWH1228FD7WATKSJ, and SPMWH1228FD7WATMSJ are LM281B+ series parts meeting all mechanical and optical specifications with higher test current (150mA) and slightly different forward voltage (2.9V or 3.0V).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series): SPMWHT541MP7WATMS0 is the recommended substitute for the SPMWHT541MP7WATGS0. Both parts belong to the LM561B Plus series and share identical optical and mechanical specifications. SPMWHT541MP7WATMS0 carries Active product status and ROHS3 compliance, providing long-term supply assurance. The improved thermal resistance (15°C/W vs. 20°C/W) offers superior thermal performance. This part is suitable for direct PCB assembly substitution without design modification.

For Parametric Equivalents (LM281B+ Series): The six LM281B+ variants (SPMWH1228FD7W2T0SJ, SPMWH1228FD7W2TKSJ, SPMWH1228FD7W2TMSJ, SPMWH1228FD7WAT0SJ, SPMWH1228FD7WATKSJ, SPMWH1228FD7WATMSJ) are functionally equivalent within the specified parameter ranges. All maintain 4000K color temperature, 90 CRI, 120° viewing angle, and identical mechanical form factor. These parts differ in forward voltage (2.9V or 3.0V) and test current (150mA vs. 65mA). Selection among these variants depends on circuit design requirements for forward voltage tolerance and current handling capability. All carry Active product status and ROHS3 compliance.

Compliance Considerations: All substitute parts meet ROHS3 compliance and EAR99 export classification. MSL rating of 2A (4 Weeks) applies to the main part; substitute parts maintain equivalent moisture sensitivity handling requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WATMS0 be used as a direct replacement for SPMWHT541MP7WATGS0?

A: Yes. Both parts are LM561B Plus series with identical color temperature (4000K), CRI (90), viewing angle (120°), and mechanical dimensions (5.00mm × 3.00mm, 0.80mm height). SPMWHT541MP7WATMS0 is Active production status with improved thermal resistance (15°C/W). No circuit modification is required.

Q: What is the difference between LM561B Plus and LM281B+ series substitutes?

A: Both series meet the same optical and mechanical specifications for this application. The primary differences are test current (65mA for LM561B Plus vs. 150mA for LM281B+) and forward voltage (2.95V for LM561B Plus vs. 2.9V or 3.0V for LM281B+). Circuit design must accommodate these electrical parameter variations.

Q: Are all LM281B+ variants interchangeable?

A: The six LM281B+ variants differ only in forward voltage (2.9V or 3.0V) and packaging suffix codes. Selection depends on circuit voltage tolerance. Parts with "W2T" designation operate at 2.9V; parts with "WAT" designation operate at 3.0V. All maintain identical optical and mechanical specifications.

Q: What does "Not For New Designs" status mean for SPMWHT541MP7WATGS0?

A: This designation indicates the part has reached end-of-life and is no longer recommended for new product development. Existing inventory remains available, but long-term supply is not assured. Active status substitutes (SPMWHT541MP7WATMS0 or LM281B+ variants) are recommended for new designs.

Q: Are there thermal performance differences between substitutes?

A: Yes. SPMWHT541MP7WATGS0 has 20°C/W thermal resistance. SPMWHT541MP7WATMS0 improves to 15°C/W. LM281B+ variants are rated at 25°C/W. For applications with thermal constraints, SPMWHT541MP7WATMS0 provides superior heat dissipation.

Q: Do all substitutes maintain the same 120° viewing angle?

A: Yes. All substitute parts maintain 120° viewing angle specification, ensuring consistent optical performance in the application.

Q: What is the significance of the packaging suffix codes (MS0, SJ)?

A: Suffix codes indicate packaging and tape reel configuration. MS0 and SJ designations represent different reel formats from Samsung. Both are Tape & Reel (TR) packaging suitable for automated assembly. Verify reel compatibility with existing pick-and-place equipment specifications.

Q: Are RoHS compliance levels equivalent between main part and substitutes?

A: The main part carries RoHS Compliant status. All substitute parts carry ROHS3 Compliant status, which represents a more recent and stringent compliance standard. ROHS3 compliance is fully backward compatible with RoHS requirements.
