Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MD5WAVHS3 are identified based on strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Series family: LM561B or LM561B Plus (same base product number SPMWHT541)
• Color specification: White, Warm
• CCT (Correlated Color Temperature): 3000K
• Mounting type: Surface Mount
• Package format: 5630 (4-SMD configuration)
• Footprint dimensions: 5.00mm x 3.00mm
• CRI (Color Rendering Index): 80
• RoHS compliance status

Allowable Variation Parameters:

• Forward voltage (Vf): Within typical operating range (2.9V to 2.95V)
• Test current: 65mA (standard test condition)
• Maximum current rating: May vary (150mA to 180mA)
• Height seated: Slight variation acceptable (0.80mm to 0.90mm)
• Thermal resistance: Consistent at 16°C/W
• Packaging format: Tape & Reel (TR)

The SPMWHT541MP5WAVMS4 qualifies as a direct substitute based on these criteria, representing an evolution within the same LM561B product family with enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The SPMWHT541MP5WAVMS4 is a qualified substitute for the SPMWHT541MD5WAVHS3 in applications requiring warm white 3000K LED lighting in the 5630 package format. The substitute part maintains identical footprint dimensions (5.00mm x 3.00mm), thermal characteristics (16°C/W), and color specifications (3000K, CRI 80).

Product Status Consideration:

The main part (SPMWHT541MD5WAVHS3) carries "Not For New Designs" status, indicating Samsung has transitioned this component to end-of-life. The substitute part (SPMWHT541MP5WAVMS4) holds "Active" product status with significantly higher inventory availability (50,200 pieces versus 792 pieces), ensuring long-term supply chain reliability.

Compliance and Certification:

Both parts maintain RoHS compliance. The substitute part achieves ROHS3 certification, representing a higher compliance standard than the main part's RoHS Compliant designation. Both parts carry identical Moisture Sensitivity Level (MSL) ratings of 2A (4 Weeks), requiring equivalent handling and storage protocols.

Electrical Performance:

Forward voltage variation between parts is minimal (2.9V to 2.95V), representing a 1.7% difference within normal operating tolerances. The substitute part's maximum current rating of 180mA exceeds the main part's 150mA rating, providing additional design margin. Test current remains constant at 65mA for both parts.

Physical Compatibility:

The substitute part features a slightly lower seated height (0.80mm versus 0.90mm), which is advantageous for space-constrained applications. Both parts use identical 5630 package format with 4-SMD configuration and are supplied in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WAVMS4 be used as a direct replacement for the SPMWHT541MD5WAVHS3 in existing designs?

A: Yes. Both parts share identical footprint dimensions (5.00mm x 3.00mm), thermal resistance (16°C/W), color specification (3000K warm white), and CRI rating (80). The substitute part's forward voltage of 2.95V is within acceptable operating range of the main part's 2.9V specification. The lower seated height (0.80mm) of the substitute part is compatible with existing PCB layouts designed for the main part's 0.90mm height.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates that Samsung has discontinued active development and promotion of the SPMWHT541MD5WAVHS3. The part remains available in limited quantities (792 pieces) but is no longer recommended for new product development. The substitute part (SPMWHT541MP5WAVMS4) with "Active" status represents the current production equivalent with substantially higher inventory availability (50,200 pieces).

Q: Are there differences in the package configuration between these parts?

A: Both parts use the 5630 package format with 4-SMD configuration. The main part specifies "Flat Lead Exposed Pad" while the substitute specifies "Flat Leads." This represents a minor lead configuration variation that does not affect PCB footprint compatibility or electrical performance.

Q: How do the electrical specifications compare?

A: Test current is identical at 65mA for both parts. Forward voltage differs by 0.05V (2.9V main part versus 2.95V substitute), representing a 1.7% variation within normal operating tolerance. The substitute part's maximum current rating of 180mA exceeds the main part's 150mA, providing additional operational margin. Both parts maintain identical thermal resistance of 16°C/W.

Q: What compliance certifications apply to each part?

A: The main part (SPMWHT541MD5WAVHS3) is RoHS Compliant. The substitute part (SPMWHT541MP5WAVMS4) is ROHS3 Compliant, representing a higher compliance standard. Both parts carry identical Moisture Sensitivity Level (MSL) ratings of 2A (4 Weeks), requiring equivalent handling and storage conditions during manufacturing and assembly.

Q: Does the substitute part provide additional technical specifications?

A: Yes. The substitute part includes specifications not provided for the main part: luminous flux at 25°C test current (32lm with range 31lm to 33lm), luminous efficacy (167 lm/W), and viewing angle (120°). These additional specifications characterize the substitute part's enhanced performance but do not affect substitution compatibility.

Q: What is the inventory status for each part?

A: The main part (SPMWHT541MD5WAVHS3) has 792 pieces in stock. The substitute part (SPMWHT541MP5WAVMS4) has 50,200 pieces in stock, providing significantly greater availability for production requirements and long-term supply chain continuity.
