Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP5WAQGS4 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color: White, Cool (5700K CCT)
• CRI: 80 minimum
• Package / Case: 4-SMD, Flat Leads (5630)
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• Size / Dimension: 5.00mm x 3.00mm
• Height - Seated (Max): 0.80mm

Electrical Compatibility Parameters:

• Voltage - Forward (Vf): 2.9V to 2.95V range
• Current - Test: 65mA to 150mA operational range
• Current - Maximum: 180mA to 200mA

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 2A or equivalent

Substitute parts are grouped into two categories: Direct Substitutes (same series, active product status) and Parametric Equivalents (different series, matching electrical and mechanical specifications).

Engineering Selection Recommendations

Direct Substitute - SPMWHT541MP5WAQ0S5:

The SPMWHT541MP5WAQ0S5 is the primary substitute for SPMWHT541MP5WAQGS4. Both parts belong to the LM561B Plus series and share identical electrical specifications (2.95V Vf, 65mA test current, 180mA maximum current). The substitute maintains the same package format (5630, 4-SMD Flat Leads), mechanical dimensions, and viewing angle (120°). The substitute has improved thermal resistance (15°C/W versus 20°C/W) and is classified as Active product status, ensuring ongoing availability and support. Both parts are RoHS Compliant. The substitute includes measured luminous flux data (36lm at 65mA test current, 188 lm/W efficiency), providing additional performance documentation.

Parametric Equivalents - SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, SPMWH1228FD5W2QMSJ:

These three parts represent the LM281B+ series and function as parametric equivalents. All three maintain identical color temperature (5700K), CRI (80), package format (5630, 4-SMD Flat Leads), mechanical dimensions, and viewing angle (120°). The key electrical difference is elevated test current (150mA versus 65mA) and maximum current rating (200mA versus 180mA). Forward voltage is slightly lower (2.9V versus 2.95V), which is within acceptable tolerance for LED applications. All three parametric equivalents are classified as Active product status and comply with ROHS3 standards. Thermal resistance is higher (25°C/W versus 20°C/W), requiring thermal design consideration in high-power applications. These parts are suitable for designs requiring higher current operation or where LM281B+ series availability is preferred.

Compliance and Certification:

All substitute parts maintain RoHS compliance (either RoHS Compliant or ROHS3 Compliant). Moisture Sensitivity Level (MSL) for the direct substitute is 2A (4 Weeks), matching the main part. All parts carry ECCN EAR99 and HTSUS 8541.41.0000 classifications.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAQ0S5 be used as a direct replacement for SPMWHT541MP5WAQGS4?

A: Yes. Both parts are LM561B Plus series LEDs with identical forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (5700K), CRI (80), and package specifications (5630, 4-SMD Flat Leads). The substitute is Active product status, whereas the main part is Not For New Designs. Mechanical and electrical compatibility is complete.

Q2: What is the difference between the direct substitute and parametric equivalents?

A: The direct substitute (SPMWHT541MP5WAQ0S5) belongs to the same LM561B Plus series with identical electrical ratings. Parametric equivalents (SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, SPMWH1228FD5W2QMSJ) are LM281B+ series parts with higher test current (150mA) and maximum current (200mA), slightly lower forward voltage (2.9V), and higher thermal resistance (25°C/W). All maintain the same color temperature, CRI, package format, and mechanical dimensions.

Q3: Are there any thermal considerations when substituting with parametric equivalents?

A: Yes. Parametric equivalents have thermal resistance of 25°C/W compared to 20°C/W for the main part and 15°C/W for the direct substitute. In thermal-constrained applications, the direct substitute SPMWHT541MP5WAQ0S5 offers superior thermal performance. Parametric equivalents are suitable for standard thermal environments but require verification in high-power or high-ambient-temperature designs.

Q4: Do all substitute parts have the same package and mounting compatibility?

A: Yes. All substitute parts use the 5630 package format with 4-SMD Flat Leads, 5.00mm x 3.00mm dimensions, and 0.80mm maximum seated height. All are Surface Mount components with 120° viewing angle. PCB footprints and reflow profiles are compatible.

Q5: What is the compliance status of substitute parts?

A: The direct substitute (SPMWHT541MP5WAQ0S5) is RoHS Compliant with MSL 2A (4 Weeks), matching the main part. Parametric equivalents are ROHS3 Compliant, which exceeds RoHS requirements. All parts carry ECCN EAR99 and HTSUS 8541.41.0000 classifications. All are suitable for regulated applications requiring RoHS compliance.

Q6: Which substitute should be selected for new designs?

A: The direct substitute SPMWHT541MP5WAQ0S5 is recommended for designs requiring identical electrical specifications and thermal performance. This part is Active product status with documented availability. Parametric equivalents are suitable if higher current operation (150mA test current) is acceptable and thermal resistance of 25°C/W meets design requirements.

Q7: Are there inventory differences between substitute options?

A: Yes. Current inventory levels are: SPMWHT541MP5WAQ0S5 (1014 Pcs), SPMWH1228FD5W2QKSJ (1048 Pcs), SPMWH1228FD5W2Q0SJ (882 Pcs), and SPMWH1228FD5W2QMSJ (666 Pcs). All parts are listed as New Original In Stock. Inventory levels should be verified with supplier for long-term supply planning.
