Key Parameters

Substitute Part Grouping Explanation

Substitution of SPMWHT541MP7WAPUS0 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color temperature: 6500K (cool white)
• Color Rendering Index: 90
• Package type: 4-SMD, Flat Leads (5630)
• Physical dimensions: 5.00mm x 3.00mm footprint, 0.80mm maximum height
• Viewing angle: 120°
• Mounting type: Surface Mount
• RoHS compliance status

Electrical Operating Parameters:

• Forward voltage range: 2.9V to 3.0V (compatible with 2.95V nominal)
• Test current: 65mA to 150mA (within maximum rating of 180mA to 200mA)
• Maximum current rating: 180mA to 200mA

Substitute parts are grouped into two categories: direct equivalents (identical series with matching product status) and parametric equivalents (different series with compatible electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - SPMWHT541MP7WAP0S0: This part is the primary substitute for SPMWHT541MP7WAPUS0. Both are LM561B Plus series devices with identical electrical specifications (2.95V, 65mA test current) and mechanical compatibility. SPMWHT541MP7WAP0S0 carries Active product status, making it the preferred choice for ongoing production and new applications. The thermal resistance improvement (15°C/W versus 20°C/W) provides enhanced thermal performance. Both parts maintain RoHS compliance and identical MSL ratings.

Parametric Equivalents - LM281B+ Series (SPMWH1228FD7W2P0SJ, SPMWH1228FD7W2PKSJ, SPMWH1228FD7W2PMSJ, SPMWH1228FD7WAP0SJ, SPMWH1228FD7WAPKSJ, SPMWH1228FD7WAPMSJ): These six parts represent the LM281B+ series and are parametric equivalents suitable for applications where forward voltage and test current variations are acceptable. All maintain 6500K color temperature, 90 CRI, 120° viewing angle, and identical 5630 package dimensions. Forward voltage ranges from 2.9V to 3.0V, and test current is 150mA. All LM281B+ variants carry Active product status and ROHS3 compliance. Selection among these six variants depends on specific forward voltage requirements (2.9V or 3.0V) and packaging configuration needs, as indicated by part number suffixes.

For applications requiring the exact electrical characteristics of the original SPMWHT541MP7WAPUS0, SPMWHT541MP7WAP0S0 is the direct equivalent. For applications with flexibility in forward voltage and test current specifications, any of the LM281B+ variants provide compatible substitution with the advantage of active product status and improved availability.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAP0S0 be used as a direct replacement for SPMWHT541MP7WAPUS0? A: Yes. Both parts are LM561B Plus series with identical forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (6500K), CRI (90), and package dimensions (5630, 5.00mm x 3.00mm). SPMWHT541MP7WAP0S0 has Active product status and improved thermal resistance (15°C/W versus 20°C/W).

Q: What is the difference between the LM561B Plus and LM281B+ series? A: The LM281B+ series operates at higher test current (150mA versus 65mA) and has higher maximum current rating (200mA versus 180mA). Forward voltage is 2.9V or 3.0V depending on part variant. Both series share identical color temperature (6500K), CRI (90), viewing angle (120°), and 5630 package dimensions. LM281B+ parts carry Active status and ROHS3 compliance.

Q: Are all LM281B+ variants mechanically interchangeable with SPMWHT541MP7WAPUS0? A: Yes. All LM281B+ variants (SPMWH1228FD7W2P0SJ, SPMWH1228FD7W2PKSJ, SPMWH1228FD7W2PMSJ, SPMWH1228FD7WAP0SJ, SPMWH1228FD7WAPKSJ, SPMWH1228FD7WAPMSJ) share identical physical dimensions (5.00mm x 3.00mm footprint, 0.80mm maximum height), 4-SMD flat lead package, and 120° viewing angle. Differences exist only in forward voltage specification (2.9V or 3.0V) and packaging configuration.

Q: What is the impact of thermal resistance differences between these parts? A: SPMWHT541MP7WAP0S0 has 15°C/W thermal resistance, while SPMWHT541MP7WAPUS0 has 20°C/W and LM281B+ variants have 25°C/W. Lower thermal resistance indicates better heat dissipation. For applications with thermal constraints, SPMWHT541MP7WAP0S0 provides superior thermal performance. For standard applications, all three thermal resistance values are acceptable within their respective current ratings.

Q: Why do some LM281B+ parts have 2.9V and others 3.0V forward voltage? A: Forward voltage variation is a normal characteristic of LED manufacturing. Parts designated with 2.9V (SPMWH1228FD7W2P0SJ, SPMWH1228FD7W2PKSJ, SPMWH1228FD7W2PMSJ) and 3.0V (SPMWH1228FD7WAP0SJ, SPMWH1228FD7WAPKSJ, SPMWH1228FD7WAPMSJ) are binned separately. Selection depends on circuit design requirements and current limiting specifications.

Q: Are there compliance differences between RoHS and ROHS3? A: ROHS3 represents the current RoHS Directive 2011/65/EU with updated substance restrictions. Both RoHS Compliant and ROHS3 Compliant designations indicate compliance with hazardous substance limitations. ROHS3 is the current standard; SPMWHT541MP7WAP0S0 carries RoHS Compliant status while LM281B+ variants carry ROHS3 Compliant status.

Q: What does MSL 2A (4 Weeks) mean? A: Moisture Sensitivity Level (MSL) 2A indicates the component can be exposed to ambient conditions of 30°C and 60% relative humidity for up to 4 weeks before soldering without requiring baking. SPMWHT541MP7WAPUS0 and SPMWHT541MP7WAP0S0 specify this rating. LM281B+ variants do not specify MSL in the provided data.
