Engineering Selection Recommendations

LM561B Plus Series Substitutes (SPMWHT541MP5WAT0S5, SPMWHT541MP5WATMS5, SPMWHT541MP5WATUS5):

These parts are electrically and thermally identical to the main part SPMWHT541MP5WATNS5. Selection among these three variants is based on product status and compliance certification:

SPMWHT541MP5WAT0S5: Active product status with RoHS Compliant certification. Recommended for new designs requiring LM561B Plus series performance.
SPMWHT541MP5WATMS5: Active product status with ROHS3 Compliant certification. Recommended when updated RoHS3 compliance is required.
SPMWHT541MP5WATUS5: Product status is "Not For New Designs." Use only for legacy system maintenance or replacement applications where design changes are not permitted.

LM561C Series Substitutes (SPMWHT541ML5XAT0S5, SPMWHT541ML5XATMS5):

These parts offer improved performance characteristics compared to the LM561B Plus series while maintaining identical optical output and physical dimensions:

Lower forward voltage (2.75V vs. 2.95V) reduces power dissipation by approximately 6.8% at 65mA test current
Improved thermal resistance (12°C/W vs. 15°C/W) provides better heat management
Higher maximum current rating (200mA vs. 180mA) permits increased operational headroom
Superior luminous efficacy (196 lm/W vs. 182 lm/W)
ROHS3 Compliant certification on both variants

Selection between LM561C variants:

SPMWHT541ML5XAT0S5: Active product status with ROHS3 Compliant certification.

Q: What is the difference between SPMWHT541MP5WATMS5 and SPMWHT541MP5WAT0S5?

A: Both parts are LM561B Plus series with identical electrical and thermal specifications. The primary difference is RoHS certification: SPMWHT541MP5WAT0S5 carries RoHS Compliant certification, while SPMWHT541MP5WATMS5 carries ROHS3 Compliant certification. Select based on your design's compliance requirements.

Q: Why does SPMWHT541MP5WATUS5 have "Not For New Designs" status?

A: This designation indicates the part is available for existing applications and legacy system support but should not be selected for new product development. Use SPMWHT541MP5WAT0S5 or SPMWHT541MP5WATMS5 for new designs requiring LM561B Plus series performance.

Q: What are the advantages of LM561C series over LM561B Plus?

A: The LM561C series provides three measurable improvements: (1) reduced forward voltage from 2.95V to 2.75V, decreasing power consumption at equivalent current; (2) improved thermal resistance from 15°C/W to 12°C/W, enabling better heat dissipation; (3) higher maximum current rating of 200mA versus 180mA, providing greater operational margin. Optical output and physical dimensions remain identical.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level (2A, 4 Weeks) and handling requirements.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical physical dimensions (5.00mm × 3.00mm), height (0.80mm), package format (4-SMD, Flat Leads), and mounting type (Surface Mount). PCB footprints and reflow profiles remain unchanged across all listed substitutes.

Q: Which substitute part has the highest inventory availability?

A: SPMWHT541ML5XATMS5 (LM561C series) has the highest inventory with 25,846 units in stock, followed by SPMWHT541MP5WATUS5 with 25,490 units.
