Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WAVMS4

The SPMWHT541MP5WAVMS4 is the direct equivalent for the SPMWHT541MP5WAVHS3. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The SPMWHT541MP5WAVMS4 carries an "Active" product status, ensuring continued availability and manufacturing support from Samsung Semiconductor. The main part SPMWHT541MP5WAVHS3 is designated "Not For New Designs," making the active substitute the appropriate choice for ongoing production requirements.

Electrical and Mechanical Compatibility: All critical electrical parameters—forward voltage, test current, maximum current, color temperature, CRI, and viewing angle—are identical between the main part and substitute. Mechanical parameters including package type, dimensions, height, and thermal resistance are fully matched.

Luminous Flux Performance: The substitute delivers 32 lumens at 65mA test current compared to 30 lumens for the main part. Both values fall within the acceptable 29–33 lumen range for this product category. The substitute exhibits higher luminous efficacy at 167 lm/W versus 156 lm/W, representing improved energy efficiency without altering circuit behavior.

Compliance and Certification: Both parts maintain RoHS compliance. The substitute carries ROHS3 certification, meeting current regulatory requirements. Moisture sensitivity level and packaging specifications are identical, ensuring compatibility with existing assembly and storage protocols.

Inventory and Supply: The SPMWHT541MP5WAVMS4 maintains significantly higher inventory levels (50,200 pieces) compared to the main part (850 pieces), providing supply security for production continuity.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MP5WAVHS3 in existing circuit designs?

A: Yes. The SPMWHT541MP5WAVMS4 is a direct substitute. All electrical parameters—forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (3000K), CRI (80), and viewing angle (120°)—are identical. Mechanical compatibility is confirmed through matching package type (4-SMD, Flat Leads), dimensions (5.00mm × 3.00mm), height (0.80mm), and thermal resistance (16°C/W). No circuit modifications are required.

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

A: The SPMWHT541MP5WAVHS3 produces 30 lumens at 65mA test current, while the SPMWHT541MP5WAVMS4 produces 32 lumens under identical test conditions. This 2-lumen difference represents approximately 6.7% higher output from the substitute. Both values fall within the acceptable 29–33 lumen specification range for this product category. The substitute also demonstrates higher luminous efficacy at 167 lm/W compared to 156 lm/W.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant. The main part carries standard RoHS certification, while the substitute carries ROHS3 certification, which reflects current regulatory standards. Both parts maintain identical moisture sensitivity levels (2A, 4 weeks) and are classified under the same ECCN (EAR99) and HTSUS codes (8541.41.0000).

Q: Why is the main part marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Samsung Semiconductor has transitioned this component to end-of-life status. This status typically reflects manufacturing phase-out or transition to newer product generations. The SPMWHT541MP5WAVMS4, marked as "Active," represents the current production equivalent and is the appropriate choice for new designs and ongoing production support.

Q: Are the packaging and handling requirements the same for both parts?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging and maintain identical moisture sensitivity levels (2A, 4 weeks). Storage, handling, and assembly procedures are interchangeable between the two parts.

Q: Can the substitute be used in applications requiring the exact 30-lumen specification?

A: The substitute produces 32 lumens, which is 2 lumens above the main part specification. If the application requires exactly 30 lumens with zero tolerance, the 32-lumen output may exceed specification limits. However, both parts operate within the same 29–33 lumen product category range, indicating this variation is within normal manufacturing tolerance for this LED series.

Q: What is the thermal performance relationship between these parts?

A: Both parts have identical thermal resistance of 16°C/W, ensuring equivalent thermal performance in circuit applications. Heat dissipation characteristics and thermal management requirements are identical.
