Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAVMS2 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color specification: White, Warm
• Color temperature: 3000K
• Forward voltage: 2.95V nominal
• Test current: 65mA
• Viewing angle: 120°
• Package type: 4-SMD, 5630 form factor
• CRI: 80 minimum
• Mounting type: Surface Mount

The SPMWHT541MP5WAVMS4 qualifies as a direct substitute based on identical alignment across all critical parameters. Both components operate at the same forward voltage, test current, color temperature, and viewing angle. The substitute belongs to the LM561B Plus series, representing an enhanced product line variant within the same LM561B family.

Engineering Selection Recommendations

The SPMWHT541MP5WAVMS4 is the designated substitute for the obsolete SPMWHT541MD5WAVMS2. Selection is based on the following engineering criteria:

Product Status Alignment: The substitute is classified as Active, ensuring continued availability and supply chain support. The main part is Obsolete, making substitution necessary for new designs and ongoing production.

Electrical Compatibility: Both components operate at identical forward voltage (2.95V) and test current (65mA), ensuring direct circuit compatibility without modification to drive electronics or current-limiting resistor calculations.

Optical Specifications: Both parts maintain 3000K color temperature and 80 CRI, preserving color rendering characteristics. The substitute delivers increased luminous flux (32 lm versus 28 lm at test current), resulting in higher luminous efficacy (167 lm/W versus 146 lm/W).

Mechanical Fit: Both components use the 5630 package format with identical footprint dimensions (5.00mm × 3.00mm). The substitute exhibits reduced seated height (0.80mm versus 0.90mm), which is compatible with existing PCB layouts.

Regulatory Compliance: The substitute meets ROHS3 Compliant status, exceeding the RoHS Compliant status of the main part. Both components are REACH Unaffected and classified as EAR99 for export control purposes.

Packaging Consideration: The main part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute is supplied in Tape & Reel (TR) format. Packaging format does not affect component electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MD5WAVMS2 without circuit modification?

A: Yes. Both components operate at 2.95V forward voltage and 65mA test current. No changes to drive circuitry, current-limiting resistors, or power supply specifications are required.

Q: What is the difference in light output between the main part and substitute?

A: At 65mA test current, the substitute produces 32 lumens compared to 28 lumens from the main part. This represents a 14% increase in luminous flux. Both maintain identical 3000K color temperature and 80 CRI.

Q: Are the physical dimensions identical?

A: The footprint dimensions are identical (5.00mm L × 3.00mm W). The substitute has a slightly reduced seated height of 0.80mm compared to 0.90mm for the main part. This difference does not affect PCB layout compatibility.

Q: What is the maximum current rating for each part?

A: The main part (SPMWHT541MD5WAVMS2) has a maximum current rating of 150mA. The substitute (SPMWHT541MP5WAVMS4) has a maximum current rating of 180mA. Both are rated for 65mA test current.

Q: Are there differences in packaging format?

A: Yes. The main part is supplied in Cut Tape (CT) & Digi-Reel® format. The substitute is supplied in Tape & Reel (TR) format. Packaging format does not affect component performance or compatibility.

Q: What is the regulatory compliance status of each part?

A: The main part is RoHS Compliant. The substitute is ROHS3 Compliant, representing a higher compliance standard. Both are REACH Unaffected and EAR99 classified.

Q: Why is the main part classified as Obsolete?

A: Product status reflects Samsung Semiconductor's product lifecycle management. The LM561B Plus series (substitute) represents the active product line continuation.

Q: Can the substitute be used in existing inventory systems designed for the main part?

A: Yes, provided the system accommodates the Tape & Reel (TR) packaging format. The electrical and mechanical specifications are compatible with existing designs.
