Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAT0S5 (LM561B Plus) This substitute maintains identical electrical and optical specifications to the main part SPMWHT541MP5WATMS5. Both are LM561B Plus series components with 2.95V forward voltage, 182 lm/W efficiency, and 180mA maximum current rating. Product status is Active. RoHS compliance is stated as RoHS Compliant. This part is suitable for direct substitution in new designs and production runs.

SPMWHT541MP5WATUS5 (LM561B Plus) This part is electrically and optically identical to SPMWHT541MP5WATMS5, maintaining the same LM561B Plus series specifications. However, product status is designated as Not For New Designs. This part is available in inventory but should not be selected for new design implementations. Use only when existing designs require continuation or when inventory of Active status parts is unavailable.

SPMWHT541ML5XAT0S5 (LM561C) This LM561C series substitute provides identical optical output (35lm at 65mA) and maintains all mechanical and package specifications. The LM561C series operates at lower forward voltage (2.75V versus 2.95V) and offers higher efficiency (196 lm/W versus 182 lm/W). Maximum current rating is 200mA versus 180mA. Thermal resistance is improved at 12°C/W versus 15°C/W. Product status is Active and ROHS3 Compliant. This part is suitable for new designs where improved thermal performance and efficiency are beneficial.

SPMWHT541ML5XATMS5 (LM561C) This LM561C series substitute is functionally equivalent to SPMWHT541ML5XAT0S5, offering the same electrical, optical, and thermal improvements over the LM561B Plus series. Product status is Active and ROHS3 Compliant. This part is suitable for new designs and provides the same performance advantages as the LM561C variant.

Selection Priority for Active Designs: For new designs, select from parts with Active product status: SPMWHT541MP5WAT0S5, SPMWHT541ML5XAT0S5, or SPMWHT541ML5XATMS5. The LM561C variants (SPMWHT541ML5XAT0S5 and SPMWHT541ML5XATMS5) offer superior thermal characteristics and efficiency. The LM561B Plus variant (SPMWHT541MP5WAT0S5) provides direct electrical equivalence to the main part.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAT0S5 (LM561C) be used as a direct replacement for SPMWHT541MP5WATMS5 (LM561B Plus)?

A: Yes. Both parts produce identical optical output (35lm at 65mA test current), operate at the same color temperature (4000K), and share identical package dimensions (5630, 5.00mm x 3.00mm) and mechanical specifications. The LM561C series operates at lower forward voltage (2.75V versus 2.95V) and provides higher efficiency (196 lm/W versus 182 lm/W). Circuit designs must accommodate the different forward voltage characteristic. Maximum current rating differs (200mA versus 180mA), allowing higher operational headroom in the LM561C variant.

Q: What is the difference between SPMWHT541MP5WATMS5 and SPMWHT541MP5WAT0S5?

A: Both parts are LM561B Plus series with identical electrical specifications (2.95V forward voltage, 182 lm/W efficiency, 180mA maximum current) and optical output (35lm at 65mA). Both maintain the same 5630 package configuration and physical dimensions. The primary difference is packaging variant designation in the part number suffix. Both are suitable for production use.

Q: Why is SPMWHT541MP5WATUS5 marked as "Not For New Designs"?

A: Product status designation indicates that while this part remains available in inventory and is electrically and optically equivalent to SPMWHT541MP5WATMS5, Samsung Semiconductor has classified it as Not For New Designs. This designation typically indicates the part is in end-of-life phase or has been superseded. New design implementations should select from parts with Active status: SPMWHT541MP5WAT0S5, SPMWHT541ML5XAT0S5, or SPMWHT541ML5XATMS5.

Q: Are all substitute parts ROHS3 compliant?

A: SPMWHT541MP5WATMS5, SPMWHT541ML5XAT0S5, and SPMWHT541ML5XATMS5 are explicitly ROHS3 Compliant. SPMWHT541MP5WAT0S5 and SPMWHT541MP5WATUS5 are listed as RoHS Compliant. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the thermal resistance difference between LM561B Plus and LM561C series?

A: LM561B Plus series (SPMWHT541MP5WATMS5 and SPMWHT541MP5WAT0S5) has thermal resistance of 15°C/W. LM561C series (SPMWHT541ML5XAT0S5 and SPMWHT541ML5XATMS5) has thermal resistance of 12°C/W. The LM561C series provides 20% better thermal performance, resulting in lower junction temperature at equivalent power dissipation.

Q: Can these parts be used interchangeably in existing production?

A: Parts with identical series designation (LM561B Plus variants: SPMWHT541MP5WATMS5 and SPMWHT541MP5WAT0S5) are directly interchangeable. LM561C series substitutes (SPMWHT541ML5XAT0S5 and SPMWHT541ML5XATMS5) require circuit verification due to different forward voltage (2.75V versus 2.95V). Designs operating at fixed current (65mA test condition) will experience identical optical output but different power dissipation. Designs using current-limiting resistors must be recalculated for the lower forward voltage.

Q: What is the MSL rating and why is it important?

A: All substitute parts carry MSL 2A (4 Weeks) rating. This indicates the component can be exposed to ambient conditions of 30°C and 85% relative humidity for up to 4 weeks before soldering without requiring baking. After 4 weeks of exposure, the component must be baked at specified temperature and time before assembly. This specification is critical for supply chain management and manufacturing process planning.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All parts use the 5630 supplier device package with dimensions of 0.197" L x 0.118" W (5.00mm x 3.00mm) and maximum seated height of 0.031" (0.80mm). All parts are 4-SMD with flat leads. PCB footprints and assembly equipment settings are identical across all substitutes.
