Variable Parameter:

• Color Temperature (CCT): 3500K (main part) vs. 3000K (one substitute)

The SPMWHT541MP7WAUMS0 is a direct parametric equivalent with identical electrical and mechanical specifications. The SPMWHT541MP7WAVMS0 differs only in color temperature (3000K vs. 3500K), making it suitable for applications where warmer color output is acceptable.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP7WAUMS0 Selection Criteria:

The SPMWHT541MP7WAUMS0 is a direct parametric equivalent to the SPMWHT541MP7WAUKS0. Both parts maintain identical electrical specifications (2.95V forward voltage, 65mA test current, 26lm luminous flux, 136 lm/W efficiency, CRI 90) and mechanical specifications (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm dimensions, 0.80mm height). The primary distinction is RoHS compliance status: SPMWHT541MP7WAUMS0 carries ROHS3 Compliant certification compared to RoHS Compliant for the main part. Both maintain identical color temperature (3500K), viewing angle (120°), and thermal resistance (15°C/W). This substitute is suitable for applications where ROHS3 compliance is required or where higher inventory availability (52082 units) is advantageous.

SPMWHT541MP7WAVMS0 Selection Criteria:

The SPMWHT541MP7WAVMS0 maintains all electrical and mechanical specifications identical to the main part with one exception: color temperature is 3000K instead of 3500K. This part is suitable for applications where a warmer color output (3000K) is acceptable or preferred. All other parameters remain constant: 2.95V forward voltage, 65mA test current, 26lm luminous flux, 136 lm/W efficiency, CRI 90, 120° viewing angle, 5630 package configuration, and 15°C/W thermal resistance. This substitute carries ROHS3 Compliant certification and offers high inventory availability (33985 units).

Both substitute parts are active in production status and maintain identical moisture sensitivity levels (2A, 4 Weeks).

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP7WAUMS0 be used as a direct replacement for SPMWHT541MP7WAUKS0?

A: Yes. The SPMWHT541MP7WAUMS0 is a direct parametric equivalent. All electrical specifications (forward voltage, test current, luminous flux, efficiency, CRI) and mechanical specifications (package type, dimensions, thermal resistance) are identical. The only difference is RoHS compliance certification (ROHS3 vs. RoHS Compliant). Both parts operate at 3500K color temperature.

Q2: What is the difference between SPMWHT541MP7WAVMS0 and the main part SPMWHT541MP7WAUKS0?

A: The SPMWHT541MP7WAVMS0 differs in color temperature only: 3000K versus 3500K. All other parameters are identical, including forward voltage (2.95V), test current (65mA), luminous flux (26lm), efficiency (136 lm/W), CRI (90), viewing angle (120°), package configuration (5630, 4-SMD flat leads), and thermal resistance (15°C/W).

Q3: Are all three parts compatible with the same PCB layout and reflow profile?

A: Yes. All three parts share identical mechanical specifications: 5630 package type, 4-SMD flat leads configuration, 5.00mm x 3.00mm dimensions, and 0.031" (0.80mm) maximum seated height. They are compatible with the same surface-mount assembly process and PCB footprint.

Q4: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 Compliant certification on SPMWHT541MP7WAUMS0 and SPMWHT541MP7WAVMS0 indicates compliance with the latest RoHS directive requirements. The main part carries RoHS Compliant status. Both certifications meet environmental and hazardous substance restrictions; ROHS3 represents the current regulatory standard.

Q5: Can SPMWHT541MP7WAVMS0 be used in applications requiring 3500K color temperature?

A: No. The SPMWHT541MP7WAVMS0 operates at 3000K color temperature, which is warmer than the 3500K specification of the main part. This difference affects color rendering in lighting applications. Use this substitute only when 3000K color temperature is acceptable for the application.

Q6: What are the moisture sensitivity handling requirements for these parts?

A: All three parts carry MSL 2A (4 Weeks) rating. This indicates the parts must be stored in dry conditions and used within 4 weeks of exposure to ambient humidity. Standard moisture barrier packaging and handling procedures apply.

Q7: Are there inventory considerations when selecting between these parts?

A: Yes. Current inventory levels differ significantly: SPMWHT541MP7WAUKS0 (823 units), SPMWHT541MP7WAUMS0 (52082 units), and SPMWHT541MP7WAVMS0 (33985 units). For high-volume production, the substitute parts offer substantially higher availability.

Q8: Do all three parts maintain the same thermal resistance characteristics?

A: Yes. All three parts have identical thermal resistance of 15°C/W, ensuring equivalent thermal performance in circuit design and thermal management calculations.
