Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAP0SC is determined by strict alignment across the following critical parameters:

Color & Spectral Characteristics: Both parts must maintain 6500K cool white color temperature and 80 CRI to ensure consistent color rendering in end-use applications.

Electrical Performance: Forward voltage (2.95V typical), test current (65mA), and luminous flux output (32 lm nominal at 25°C) must remain within specified tolerances to ensure circuit compatibility and photometric consistency.

Mechanical Compatibility: Package format (5630, 4-SMD), mounting type (surface mount), and physical dimensions (5.00mm × 3.00mm) must be identical to ensure PCB footprint compatibility.

Thermal & Reliability Characteristics: Thermal resistance, maximum current rating, and moisture sensitivity level must support equivalent thermal management and storage requirements.

The SPMWHT541MP5WAPKS4 (LM561B Plus variant) qualifies as a direct substitute based on matching all critical parameters within the allowed tolerance ranges specified in this product category.

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WAPKS4

The SPMWHT541MP5WAPKS4 is the qualified substitute for SPMWHT541MD5WAP0SC based on the following engineering criteria:

Electrical Equivalence: Both parts operate at identical forward voltage (2.95V) and test current (65mA), with luminous flux output within specified tolerance ranges (32 lm vs. 33 lm nominal). The substitute's higher maximum current rating (180mA vs. 150mA) provides additional design margin without affecting nominal operating conditions.

Photometric Consistency: Color temperature (6500K), CRI (80), viewing angle (120°), and luminous efficacy (167 lm/W) are identical across both parts, ensuring color rendering and light distribution characteristics remain unchanged in end applications.

Mechanical Compatibility: Both parts use identical 5630 package format with 5.00mm × 3.00mm footprint. The substitute features a lower seated height (0.80mm vs. 0.90mm), which is advantageous for space-constrained applications and does not create compatibility issues.

Thermal Performance: The substitute demonstrates improved thermal resistance (15°C/W vs. 16°C/W), supporting equivalent or enhanced thermal management in circuit designs.

Compliance & Production Status: The substitute carries ROHS3 compliance (vs. RoHS Compliant) and Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain identical moisture sensitivity level (2A, 4 Weeks).

Recommendation: The SPMWHT541MP5WAPKS4 is suitable for direct substitution in all applications currently using SPMWHT541MD5WAP0SC. No circuit modifications or thermal redesign are required.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAPKS4 be used as a direct replacement for SPMWHT541MD5WAP0SC without PCB modifications?

A: Yes. Both parts share identical 5630 package footprint (5.00mm × 3.00mm) and 4-SMD surface mount configuration. The substitute's lower seated height (0.80mm vs. 0.90mm) does not create clearance conflicts. No PCB layout changes are required.

Q: Are the electrical characteristics identical between these two parts?

A: Forward voltage (2.95V typical) and test current (65mA) are identical. Luminous flux output differs slightly (32 lm vs. 33 lm nominal), but both values fall within the same acceptable tolerance range for 6500K cool white LEDs. The substitute's higher maximum current rating (180mA vs. 150mA) provides additional operational margin.

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

A: Both descriptions refer to compatible 4-SMD surface mount configurations within the 5630 package family. The functional and mechanical compatibility remains unchanged for PCB assembly and thermal management purposes.

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

A: This status indicates the SPMWHT541MD5WAP0SC has been superseded in Samsung's product portfolio. The SPMWHT541MP5WAPKS4 (LM561B Plus) represents the active production equivalent, ensuring long-term supply availability and design continuity for new and ongoing applications.

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

A: The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. Both meet current environmental and hazardous substance restrictions. The substitute's enhanced compliance classification reflects current regulatory standards.

Q: What is the thermal advantage of the substitute part?

A: The SPMWHT541MP5WAPKS4 features 15°C/W thermal resistance compared to 16°C/W for the main part. This 1°C/W improvement supports slightly better heat dissipation in high-density LED array applications, though both parts are suitable for equivalent thermal management designs.

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

A: Yes. Both parts carry identical Moisture Sensitivity Level (2A, 4 Weeks), requiring the same storage conditions, handling procedures, and reflow soldering parameters. No changes to supply chain or assembly processes are necessary.
