Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAVKS5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Color Temperature: 3000K (Warm White)
• Viewing Angle: 120°
• Package Type: 4-SMD, Flat Leads (5630)
• Physical Dimensions: 5.00mm x 3.00mm
• Mounting Type: Surface Mount
• Color Rendering Index (CRI): 80
• Luminous Flux @ 25°C: 34lm (33lm to 35lm range)
• Test Current: 65mA

Allowable Variation Parameters:

• Forward Voltage (Vf): 2.75V to 2.95V (within LM561B Plus and LM561C series specifications)
• Maximum Current: 180mA to 200mA (series-dependent)
• Lumens per Watt: 177 to 190 lm/W (efficiency variation between LM561B Plus and LM561C)
• Thermal Resistance: 12°C/W to 15°C/W (package thermal performance variation)
• Series: LM561B Plus or LM561C (both compatible within base product family SPMWHT541)

All substitute parts maintain identical electrical performance at the 65mA test current and deliver the same luminous output. Differences in forward voltage and thermal resistance reflect inherent series-level design variations that do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

SPMWHT541MP5WAVMS5 is the preferred substitute when the SPMWHT541MP5WAVKS5 is unavailable. Both components are LM561B Plus series devices with identical electrical specifications (2.95V forward voltage, 180mA maximum current, 177 lm/W efficiency). SPMWHT541MP5WAVMS5 carries ROHS3 Compliant certification and maintains Active product status with significantly higher inventory availability (26,898 units).

SPMWHT541ML5XAVMS5 provides an alternative within the LM561C series. This substitute operates at a lower forward voltage (2.75V) and supports higher maximum current (200mA), delivering improved efficiency at 190 lm/W. The thermal resistance is reduced to 12°C/W, providing superior thermal performance. SPMWHT541ML5XAVMS5 is ROHS3 Compliant with Active status and the highest inventory level (10,671 units).

Secondary Substitutes (Active Status):

SPMWHT541ML5XAV0S5 is an LM561C series alternative with identical performance characteristics to SPMWHT541ML5XAVMS5, including 2.75V forward voltage, 200mA maximum current, and 12°C/W thermal resistance. This part maintains RoHS Compliant status and Active product status with 992 units in inventory.

Legacy Substitute (Not Recommended for New Designs):

SPMWHT541MP5WAVUS5 is an LM561B Plus series component with specifications matching the main part (2.95V, 180mA maximum current). However, this part carries a "Not For New Designs" product status designation and should not be selected for new applications. It remains available with 11,711 units in inventory for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAVMS5 (LM561C) be used as a direct replacement for SPMWHT541MP5WAVKS5 (LM561B Plus)?

A: Yes. Both components deliver identical luminous output (34 lumens at 65mA test current) and operate at the same 3000K color temperature with 120° viewing angle. The LM561C operates at a lower forward voltage (2.75V versus 2.95V) and provides higher efficiency (190 lm/W versus 177 lm/W). These differences represent improved performance characteristics and do not affect functional compatibility. The 5630 package dimensions and surface-mount configuration are identical.

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

A: The LM561C series represents an improved generation with lower forward voltage (2.75V), higher maximum current rating (200mA), better efficiency (190 lm/W), and superior thermal resistance (12°C/W). The LM561B Plus maintains a higher forward voltage (2.95V) and lower maximum current (180mA). At the standard 65mA test current, both series deliver identical luminous output and color characteristics. Selection between series depends on circuit design requirements and thermal management considerations.

Q: Are all substitute parts mechanically compatible with the original part?

A: Yes. All substitute parts use the identical 5630 package (4-SMD, Flat Leads) with dimensions of 5.00mm x 3.00mm and maximum seated height of 0.80mm. All components are surface-mount devices with flat leads suitable for standard reflow soldering processes. No PCB layout modifications are required.

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

A: The forward voltage difference reflects improved LED junction design in the LM561C series. At the 65mA test current, the LM561C operates at 0.20V lower forward voltage, resulting in reduced power dissipation and improved efficiency. In constant-current driver circuits, this voltage difference is automatically compensated. In voltage-regulated circuits, the lower forward voltage may require minor resistor adjustments to maintain the same current level.

Q: Should SPMWHT541MP5WAVUS5 be used in new product designs?

A: No. SPMWHT541MP5WAVUS5 carries a "Not For New Designs" product status. This designation indicates that Samsung Semiconductor has transitioned this part to legacy support only. For new designs, select SPMWHT541MP5WAVMS5 (LM561B Plus, Active status) or SPMWHT541ML5XAVMS5 (LM561C, Active status).

Q: What is the thermal resistance specification and why does it vary between parts?

A: Thermal resistance (15°C/W for LM561B Plus, 12°C/W for LM561C) indicates the temperature rise per watt of power dissipation. The LM561C series features improved thermal design with lower thermal resistance, enabling better heat dissipation from the LED junction. In applications with thermal constraints, the LM561C series (12°C/W) provides superior thermal performance. In standard applications, both thermal resistance values are acceptable.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts meet RoHS compliance requirements. SPMWHT541MP5WAVKS5, SPMWHT541ML5XAV0S5, and SPMWHT541MP5WAVUS5 carry RoHS Compliant certification. SPMWHT541ML5XAVMS5 and SPMWHT541MP5WAVMS5 carry ROHS3 Compliant certification, representing the current RoHS standard. Both compliance levels are acceptable for component selection.

Q: What is the Moisture Sensitivity Level (MSL) and how does it affect handling?

A: All parts carry MSL 2A (4 Weeks) rating. This indicates the components can be stored in standard laboratory conditions (23°C, 50% relative humidity) for up to 4 weeks after packaging opening without requiring baking. For extended storage or humid environments, components must be stored in moisture-barrier packaging or baked according to IPC-A-610 standards before reflow soldering.
