• Maximum seated height: 0.80mm
• Mounting type: Surface Mount

Electrical Compatibility:

• Color specification: White, Cool
• Color temperature: 5000K
• Viewing angle: 120°
• CRI: 80
• Forward voltage range: Compatible with 2.75V nominal operation
• Test current: 65mA
• Maximum current rating: Sufficient for 200mA operation

Regulatory & Environmental:

• RoHS compliance status
• Moisture Sensitivity Level: 2A (4 Weeks)
• ECCN and HTSUS classifications

The SPMWHT541MP5WARKS4 qualifies as a direct substitute based on identical mechanical form factor, matching color temperature and CRI specifications, compatible electrical operating parameters, and equivalent regulatory compliance. The primary distinction lies in product series evolution (LM561B Plus versus LM561C) and active manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WARKS4

The SPMWHT541MP5WARKS4 is the qualified substitute for SPMWHT541ML5XARGS0 based on the following engineering criteria:

Mechanical Fit: Both components share identical 5630 package geometry (5.00mm × 3.00mm footprint, 0.80mm maximum height), ensuring direct PCB compatibility without layout modifications.

Electrical Operation: The substitute operates at 2.95V forward voltage compared to the main part's 2.75V, representing a 0.20V increase. At the standard 65mA test current, this voltage differential is within acceptable circuit design margins for typical LED driver implementations. The substitute's maximum current rating of 180mA accommodates the main part's 200mA specification with a 20mA margin reduction.

Optical Characteristics: Both components deliver 5000K cool white light with 80 CRI, maintaining identical color rendering and correlated color temperature. The 120° viewing angle specification is preserved. Luminous flux at 25°C differs (34lm substitute versus 38lm main part), representing approximately 10.5% lower output. This difference falls within typical manufacturing tolerance bands for LED components.

Product Status & Compliance: The substitute carries "Active" product status, ensuring continued manufacturing availability and supply chain support. Both components meet RoHS compliance requirements, with the substitute meeting the newer ROHS3 standard. Moisture sensitivity level and handling requirements remain identical at 2A (4 Weeks).

Thermal Considerations: The substitute exhibits 15°C/W thermal resistance compared to the main part's 12°C/W, representing a 3°C/W increase. Thermal design calculations should account for this difference in high-temperature or high-density applications.

Packaging Format: The main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both are standard distribution methods; format selection depends on assembly process requirements and order quantities.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WARKS4 be used as a direct drop-in replacement for SPMWHT541ML5XARGS0?

A: Yes, for most applications. Both components share identical mechanical form factors (5630 package, 5.00mm × 3.00mm, 0.80mm height) and surface mount compatibility. PCB footprints and assembly processes require no modification. However, circuit designs operating at the maximum 200mA current specification should be reviewed, as the substitute is rated to 180mA maximum.

Q: What is the impact of the 0.20V forward voltage difference?

A: The substitute's 2.95V forward voltage versus the main part's 2.75V represents a 0.20V increase. For constant-current LED drivers (the standard implementation), this voltage difference is absorbed by the driver's compliance voltage headroom and does not affect LED operation. For voltage-regulated circuits, verify that the power supply provides sufficient voltage margin above 2.95V to maintain proper current regulation.

Q: How does the 10.5% luminous flux difference affect system performance?

A: The substitute delivers 34lm at 25°C compared to the main part's 38lm, a difference of approximately 4 lumens. In applications where absolute light output is critical, this reduction should be evaluated against system design margins. For most general illumination applications, this difference is within acceptable tolerance. Thermal flux measurements at 85°C should be obtained from the manufacturer for high-temperature operating conditions.

Q: Are there packaging format implications for assembly?

A: The main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Tape & Reel is optimized for high-volume automated assembly, while Cut Tape is suitable for lower volumes or manual handling. Assembly equipment compatibility should be verified with your manufacturing partner. Both formats meet identical moisture sensitivity requirements (2A, 4 Weeks).

Q: Does the higher thermal resistance of the substitute affect reliability?

A: The substitute's 15°C/W thermal resistance compared to the main part's 12°C/W represents a 3°C/W increase. In applications with significant thermal load or high ambient temperatures, this difference may result in higher junction temperatures. Thermal modeling should be performed for applications operating above 50°C ambient or with high current density. For standard indoor lighting applications at moderate temperatures, this difference is typically negligible.

Q: What is the significance of ROHS3 compliance on the substitute?

A: ROHS3 represents an updated regulatory standard that maintains the same restricted substance requirements as the original RoHS specification. Both components are compliant with hazardous substance restrictions. The substitute's ROHS3 certification indicates current manufacturing compliance with the latest regulatory framework, supporting long-term supply chain stability.

Q: Can the substitute be used in new product designs?

A: Yes. The substitute carries "Active" product status, indicating it is approved for new designs and supported by the manufacturer for ongoing production. The main part's "Not For New Designs" status makes the substitute the appropriate choice for new development efforts requiring Samsung LM561-series cool white 5000K LEDs in 5630 packages.
