Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-0008B5 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) must match to ensure PCB layout compatibility without redesign.

Optical Compatibility: Color (white) and viewing angle (120°) must remain consistent for application performance.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings must fall within acceptable operating ranges for the circuit design. Luminous flux output at 25°C and test current conditions should maintain functional equivalence.

Environmental & Compliance: Moisture sensitivity level (MSL 2A), REACH status, and thermal resistance characteristics must be compatible with assembly and operational requirements.

The MX3AWT-A1-0000-0008B4 qualifies as a substitute based on matching mechanical package, optical properties, and environmental specifications, despite differences in electrical operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008B4 is available as an active product from CreeLED, Inc., providing supply continuity for the obsolete MX3SWT-A1-0000-0008B5. Both components share identical mechanical packaging, optical characteristics (white color, 120° viewing angle), and environmental compliance (MSL 2A, REACH Unaffected).

The primary design consideration is the significant difference in electrical operating parameters: the substitute operates at 3.7V typical forward voltage with 350mA test current, compared to 10.7V and 115mA for the main part. Circuit redesign of the LED drive circuit is required to accommodate these electrical differences. Both parts deliver equivalent luminous flux (77lm) at their respective test currents, though efficiency differs slightly (63 lm/W versus 59 lm/W).

The MX3AWT-A1-0000-0008B4 carries RoHS compliance certification, providing additional environmental qualification for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008B4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008B5?

A: No. While both components share identical mechanical packaging and footprint dimensions, the electrical operating parameters differ substantially. The substitute requires a different LED driver circuit designed for 3.7V forward voltage and 350mA test current. PCB layout modifications to the power delivery circuit are necessary.

Q: Are the package dimensions and mounting footprints identical?

A: Yes. Both parts use 2-SMD gull wing exposed pad packaging with 5.00mm x 5.00mm footprint and 1.48mm maximum seated height. No PCB layout changes are required for component placement.

Q: What is the impact of the different forward voltage specifications?

A: The MX3AWT-A1-0000-0008B4 operates at 3.7V typical forward voltage, requiring a different power supply voltage or LED driver topology compared to the 10.7V requirement of the MX3SWT-A1-0000-0008B5. This is a critical design parameter that must be addressed in circuit redesign.

Q: Do both parts meet the same environmental and compliance standards?

A: Both components are REACH Unaffected and carry MSL 2A (4 Weeks) moisture sensitivity ratings. The substitute additionally carries RoHS compliance certification. Thermal resistance is identical at 11°C/W for both parts.

Q: What is the luminous flux equivalence between these parts?

A: Both parts deliver 77lm (74lm ~ 81lm) at 25°C, meeting equivalent light output specifications. However, this is achieved at different test currents (115mA for the main part, 350mA for the substitute), resulting in different efficiency ratings (63 lm/W versus 59 lm/W respectively).
