Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP5WAUMS5 is determined by the following critical parameters:

Primary Substitution Criteria:

Color Temperature (CCT): 3500K or 3000K variants
Forward Voltage (Vf): 2.75V (LM561C series) or 2.95V (LM561B Plus series)
Test Current: 65mA
Luminous Flux: 34lm (33–35lm range)
Package Type: 4-SMD, Flat Leads in 5630 form factor
Viewing Angle: 120°
CRI: 80
Mounting: Surface Mount

Series Compatibility: The LM561B Plus and LM561C series share identical mechanical dimensions, electrical test parameters, and optical characteristics. The primary difference is forward voltage: LM561B Plus operates at 2.95V while LM561C operates at 2.75V. Both series are compatible within the same PCB footprint and thermal environment.

Packaging Variants: Substitutes are available in Tape & Reel (TR) and Cut Tape (CT) packaging. Tape & Reel is standard for high-volume production; Cut Tape is suitable for lower-volume applications.

Engineering Selection Recommendations

For Active Product Status Applications: Select SPMWHT541MP5WAU0S5 (LM561B Plus, 3500K, TR packaging) or SPMWHT541MP5WAVMS5 (LM561B Plus, 3000K, TR packaging) to maintain series consistency with the original part. Both maintain identical forward voltage (2.95V), thermal resistance (15°C/W), and maximum current (180mA) specifications.

For LM561C Series Substitution (Lower Forward Voltage): SPMWHT541ML5XAUMS5 (3500K, TR) or SPMWHT541ML5XAVMS5 (3000K, TR) provide improved thermal performance (12°C/W versus 16°C/W) and higher maximum current rating (200mA versus 180mA). Forward voltage reduction from 2.95V to 2.75V requires circuit verification for constant-current driver compatibility.

For Cut Tape Packaging: SPMWHT541ML5XAU0S5 (LM561C, 3500K, CT) is available for applications requiring lower-volume component quantities.

Compliance Considerations: All substitute parts maintain RoHS compliance and 2A Moisture Sensitivity Level (4 Weeks). Parts marked "Not For New Designs" (SPMWHT541MP5WAUUS5, SPMWHT541MP5WAVUS5) are available for legacy system support but should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAUMS5 (LM561C) directly replace SPMWHT541MP5WAUMS5 (LM561B Plus)?

A: Electrical substitution is possible within the same PCB footprint and thermal environment. The primary difference is forward voltage: LM561C operates at 2.75V versus LM561B Plus at 2.95V. Constant-current LED drivers must be verified to operate within the lower voltage range. Mechanical compatibility is confirmed: both use 4-SMD, Flat Leads in 5630 package with identical 5.00mm × 3.00mm dimensions and 0.80mm maximum height.

Q: What is the difference between 3500K and 3000K color temperature variants?

A: Color temperature is the only parameter that differs between SPMWHT541MP5WAUMS5 (3500K) and SPMWHT541MP5WAVMS5 (3000K). All other electrical, optical, and mechanical specifications remain identical. Selection depends on application lighting requirements. Both maintain 34lm luminous flux and 80 CRI.

Q: Why does LM561C show higher lumens per watt (190 lm/W) than LM561B Plus (177 lm/W)?

A: The LM561C series achieves higher efficiency due to lower forward voltage (2.75V versus 2.95V) at identical test current (65mA) and luminous flux (34lm). This results in lower power dissipation and improved thermal resistance (12°C/W versus 16°C/W).

Q: Are Tape & Reel and Cut Tape packages mechanically interchangeable?

A: Yes. Both packaging formats contain identical components in the same 5630 form factor with matching electrical and mechanical specifications. Packaging selection is determined by production volume and assembly equipment compatibility, not component performance.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" (SPMWHT541MP5WAUUS5, SPMWHT541MP5WAVUS5) are available for existing product support and legacy system maintenance. Samsung Semiconductor recommends selecting parts with "Active" status for new product development to ensure long-term supply availability and manufacturing consistency.

Q: Can I use SPMWHT541ML5XAU0S5 (Cut Tape) in high-volume production?

A: Cut Tape packaging is suitable for applications with lower component quantities or manual assembly processes. For high-volume automated production, Tape & Reel packaging (SPMWHT541ML5XAUMS5) is the standard format and provides better handling efficiency.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed maintain RoHS compliance status. SPMWHT541MP5WAU0S5 and SPMWHT541ML5XAUMS5 carry ROHS3 certification; remaining parts carry standard RoHS Compliant status. All meet Moisture Sensitivity Level 2A (4 Weeks) requirements.
