Engineering Selection Recommendations

For Active Product Status Applications:

SPMWHT541MP5WATKS5, SPMWHT541MP5WAT0S5, and SPMWHT541MP5WATMS5 are all active products within the LM561B Plus series and are suitable for new designs. SPMWHT541ML5XAT0S5 and SPMWHT541ML5XATMS5 are active LM561C series alternatives with improved thermal characteristics (12°C/W versus 15°C/W) and higher maximum current rating (200mA versus 180mA).

For RoHS Compliance:

SPMWHT541MP5WATKS5 and SPMWHT541MP5WAT0S5 carry RoHS Compliant certification. SPMWHT541MP5WATMS5, SPMWHT541ML5XAT0S5, and SPMWHT541ML5XATMS5 carry ROHS3 Compliant certification. Both certifications satisfy RoHS requirements; ROHS3 represents the current standard.

For Inventory Availability:

SPMWHT541ML5XATMS5 (25846 Pcs) and SPMWHT541MP5WATUS5 (25490 Pcs) offer highest stock levels. SPMWHT541MP5WATMS5 (2088 Pcs) offers lowest stock among active products.

For Electrical Performance:

LM561C series substitutes (SPMWHT541ML5XAT0S5, SPMWHT541ML5XATMS5) deliver 196 lm/W efficiency versus 182-183 lm/W for LM561B Plus series, with lower forward voltage (2.75V versus 2.95V). These characteristics reduce power dissipation in current-limited applications.

Obsolescence Consideration:

SPMWHT541MP5WATUS5 carries "Not For New Designs" status and should not be selected for new product development despite high inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAT0S5 (LM561C) directly replace SPMWHT541MP5WATKS5 (LM561B Plus)?

A: Yes. Both parts maintain identical flux output (35lm), test current (65mA), color temperature (4000K), CRI (80), viewing angle (120°), package dimensions (5.00mm x 3.00mm), and mounting type (4-SMD, Flat Leads, 5630 package). The LM561C series features lower forward voltage (2.75V versus 2.95V) and improved thermal resistance (12°C/W versus 15°C/W), making it functionally equivalent with enhanced thermal performance.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant certifications?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current standard revision. Both are acceptable for RoHS-regulated applications. Selection between them depends on customer or regional requirements.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging format, maintaining consistency with the main part SPMWHT541MP5WATKS5.

Q: What is the significance of the forward voltage difference between LM561B Plus (2.95V) and LM561C (2.75V)?

A: The 0.20V difference affects circuit power dissipation and driver design. LM561C series requires lower voltage to achieve the same 65mA test current, resulting in reduced power consumption. This difference is material in current-limited LED driver applications.

Q: Can SPMWHT541MP5WATUS5 be used in new designs?

A: No. SPMWHT541MP5WATUS5 carries "Not For New Designs" product status. This designation indicates the part is in end-of-life phase. Select SPMWHT541MP5WATKS5, SPMWHT541MP5WAT0S5, SPMWHT541MP5WATMS5, SPMWHT541ML5XAT0S5, or SPMWHT541ML5XATMS5 for new product development.

Q: What is Moisture Sensitivity Level (MSL) 2A (4 Weeks)?

A: MSL 2A indicates the component can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 4 weeks before soldering without requiring baking. All listed parts share this specification.

Q: Are the thermal resistance values critical for component selection?

A: Thermal resistance becomes critical in high-current or high-ambient-temperature applications. LM561C series (12°C/W) dissipates heat more efficiently than LM561B Plus series (15°C/W). For applications operating near maximum current ratings or elevated temperatures, LM561C series is preferred.
