Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAW0S2 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color and correlated color temperature (CCT): White, Warm 2700K
• Forward voltage (Vf): 2.95V nominal
• Test current: 65mA
• Viewing angle: 120°
• Package format: 5630 (4-SMD configuration)
• Physical dimensions: 5.00mm × 3.00mm footprint
• CRI: 80 minimum

Allowable Variation Ranges:

• Luminous flux: Substitute parts must operate within the functional range established by the main part's performance envelope
• Maximum current rating: Substitute parts may exceed the main part's 150mA maximum
• Thermal resistance: Substitute parts may demonstrate improved thermal performance (lower °C/W values)
• Height: Substitute parts with reduced seated height remain compatible with the same PCB layout

The SPMWHT541MP5WAW0S4 qualifies as a direct substitute based on identical electrical characteristics, matching color temperature, equivalent forward voltage, and compatible 5630 package footprint.

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WAW0S4

The SPMWHT541MP5WAW0S4 is the qualified substitute for the obsolete SPMWHT541MD5WAW0S2. Selection is based on the following engineering criteria:

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

Optical Compatibility: Both parts deliver warm white light at 2700K with 80 CRI, maintaining color temperature and rendering characteristics required for the application.

Mechanical Compatibility: Identical 5630 package footprint and 5.00mm × 3.00mm dimensions ensure direct PCB layout compatibility. The substitute part's reduced height (0.80mm vs. 0.90mm) presents no clearance issues.

Compliance Status: The substitute part carries ROHS3 certification, exceeding the RoHS Compliant status of the main part and meeting current regulatory requirements.

Product Availability: The substitute part is classified as Active with 45,709 units in stock, ensuring supply continuity compared to the obsolete main part.

Performance Enhancement: The substitute part delivers 31 lumens at 65mA versus 27 lumens for the main part, representing a 15% efficiency improvement. Maximum current rating increases from 150mA to 180mA, and thermal resistance improves from 16°C/W to 15°C/W.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAW0S4 be used as a direct replacement for SPMWHT541MD5WAW0S2 without circuit modifications?

A: Yes. Both parts share identical forward voltage (2.95V), test current (65mA), and viewing angle (120°). No changes to drive circuitry, current-limiting resistors, or optical design are required.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads" package configurations?

A: Both configurations are 4-SMD packages in the 5630 form factor. The main part includes an exposed thermal pad for enhanced heat dissipation; the substitute part uses flat leads. Both are compatible with standard 5630 PCB footprints.

Q: Does the higher luminous flux of the substitute part (31 lm vs. 27 lm) affect circuit operation?

A: No. Luminous flux is a light output characteristic determined by the LED's internal design. Circuit operation depends on forward voltage and current, which are identical between both parts. The higher flux represents improved efficiency at the same operating point.

Q: Are there any thermal management differences between these parts?

A: The substitute part demonstrates improved thermal performance with 15°C/W thermal resistance compared to 16°C/W for the main part. This represents a 6% improvement and indicates better heat dissipation capability. Both parts are suitable for the same thermal management approaches.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part's Active status ensures long-term availability and supply continuity. The main part's Obsolete status indicates Samsung Semiconductor has discontinued production, making the Active substitute essential for ongoing production requirements.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 2A (4 Weeks) rating, requiring identical storage and handling protocols. No changes to moisture control procedures are necessary when transitioning to the substitute part.

Q: Can the substitute part handle higher current than the main part?

A: Yes. The substitute part's maximum current rating is 180mA compared to 150mA for the main part. However, at the standard 65mA test current, both parts operate identically. Higher current capability provides design flexibility for future applications without requiring component replacement.
