Key Parameters

Substitute Part Grouping Explanation

Substitution of SPMWHT541MP7WAQGS0 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color specification: White, Cool
• Correlated Color Temperature (CCT): 5700K
• Color Rendering Index (CRI): 90
• Package format: 4-SMD, Flat Leads in 5630 supplier package
• Mounting type: Surface Mount
• Physical dimensions: 5.00mm x 3.00mm footprint, 0.80mm maximum seated height
• Compliance: RoHS Compliant

Secondary Compatibility Parameters:

• Forward voltage (Vf): 2.9V to 3.0V range acceptable
• Test current: 65mA to 150mA range
• Maximum current rating: 180mA to 200mA
• Viewing angle: 120°
• Thermal resistance: 15°C/W to 25°C/W

Substitute parts are grouped into two categories: direct equivalents (same series, LM561B Plus) and parametric equivalents (alternative series, LM281B+). All substitutes maintain identical physical package dimensions, color temperature, and CRI specifications, ensuring mechanical and optical compatibility with existing PCB designs and optical systems.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended for Existing Designs):

SPMWHT541MP7WAQ0S0 is the primary substitute for SPMWHT541MP7WAQGS0. Both components belong to the LM561B Plus series and share identical electrical and optical specifications. SPMWHT541MP7WAQ0S0 carries Active product status, ensuring long-term availability and supply chain continuity. This part features improved thermal resistance (15°C/W versus 20°C/W), providing superior thermal performance in the same package footprint. RoHS Compliant certification matches the original part. This substitute requires no circuit redesign and provides direct PCB compatibility.

Parametric Equivalents (Alternative Series):

The LM281B+ series parts (SPMWH1228FD7W2Q0SJ, SPMWH1228FD7W2QKSJ, SPMWH1228FD7W2QMSJ, SPMWH1228FD7WAQ0SJ, SPMWH1228FD7WAQKSJ, SPMWH1228FD7WAQMSJ) are parametric equivalents with Active product status and ROHS3 Compliant certification. These parts maintain identical package dimensions, color temperature (5700K), CRI (90), and viewing angle (120°). Key differences include:

• Forward voltage: 2.9V to 3.0V (versus 2.95V main part)
• Test current: 150mA (versus 65mA main part)
• Maximum current: 200mA (versus 180mA main part)
• Thermal resistance: 25°C/W (versus 20°C/W main part)

LM281B+ substitutes are suitable for applications where higher current operation is acceptable and forward voltage tolerance permits 2.9V to 3.0V operation. Circuit current-limiting design must accommodate 150mA test current specification.

Compliance Considerations:

All substitute parts maintain RoHS compliance. LM281B+ series carries ROHS3 Compliant and REACH Unaffected certifications, exceeding the RoHS Compliant status of the original part. Moisture Sensitivity Level (MSL) for the main part is 2A (4 Weeks); verify MSL specifications for LM281B+ series in detailed datasheets if storage conditions exceed standard industrial environments.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP7WAQ0S0 be used as a direct replacement for SPMWHT541MP7WAQGS0 without circuit modification?

A: Yes. SPMWHT541MP7WAQ0S0 is a direct equivalent with identical forward voltage (2.95V), test current (65mA), color temperature (5700K), CRI (90), package format (4-SMD, Flat Leads, 5630), and physical dimensions (5.00mm x 3.00mm, 0.80mm height). No circuit redesign is required. The substitute features improved thermal resistance (15°C/W), which enhances thermal performance in existing designs.

Q2: What are the key differences between LM561B Plus and LM281B+ series substitutes?

A: Both series share identical color temperature (5700K), CRI (90), viewing angle (120°), and package dimensions. The primary differences are: (1) Forward voltage: LM561B Plus operates at 2.95V; LM281B+ operates at 2.9V to 3.0V depending on part number suffix; (2) Test current: LM561B Plus at 65mA; LM281B+ at 150mA; (3) Maximum current: LM561B Plus at 180mA; LM281B+ at 200mA; (4) Thermal resistance: LM561B Plus at 20°C/W; LM281B+ at 25°C/W. Circuit current-limiting design must accommodate the higher test current of LM281B+ parts.

Q3: Are all substitute parts mechanically compatible with existing PCB designs?

A: Yes. All substitute parts maintain identical package format (4-SMD, Flat Leads), supplier device package (5630), physical dimensions (5.00mm x 3.00mm), and maximum seated height (0.80mm). Direct PCB footprint compatibility is confirmed across all substitutes.

Q4: Which substitute part offers the best thermal performance?

A: SPMWHT541MP7WAQ0S0 provides the lowest thermal resistance at 15°C/W, compared to 20°C/W for the original part and 25°C/W for LM281B+ series substitutes. This makes SPMWHT541MP7WAQ0S0 the optimal choice for thermally constrained applications.

Q5: What is the difference between the various LM281B+ part numbers (W2Q0SJ, W2QKSJ, W2QMSJ, WAQ0SJ, WAQKSJ, WAQMSJ)?

A: The LM281B+ series parts differ in forward voltage specification: parts with "W2Q" suffix operate at 2.9V typical forward voltage; parts with "WAQ" suffix operate at 3.0V typical forward voltage. All other electrical and optical parameters remain identical. Selection depends on circuit voltage tolerance and current-limiting design requirements.

Q6: Can LM281B+ series parts be used in applications designed for 65mA operation?

A: LM281B+ parts are rated for 150mA test current and 200mA maximum current. They can be used in 65mA applications if the circuit current-limiting design accommodates the higher current rating. However, verify that the application's optical output requirements align with the higher current specification, as luminous output may differ from the original 65mA design point.

Q7: What is the product status significance for component selection?

A: The original part SPMWHT541MP7WAQGS0 is marked "Not For New Designs," indicating end-of-life status with limited future availability. All substitute parts carry "Active" product status, ensuring continued manufacturing, supply chain availability, and long-term support. Active status is critical for production continuity and design longevity.

Q8: Are there compliance differences between RoHS Compliant and ROHS3 Compliant certifications?

A: ROHS3 Compliant represents the current RoHS Directive 2011/65/EU standard with updated substance restrictions. RoHS Compliant indicates compliance with earlier RoHS standards. ROHS3 Compliant parts (all LM281B+ substitutes) meet current regulatory requirements and are preferred for new production and long-term compliance assurance.
