Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MX3SWT-A1-0000-0009B7 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) must match to ensure PCB footprint compatibility.

Optical Compatibility: Color (White) and viewing angle (120°) must remain consistent with the original design intent.

Thermal Compatibility: Thermal resistance of package (11°C/W) establishes thermal performance baseline.

Electrical Compatibility: Forward voltage (Vf), test current, maximum current rating, and luminous flux output determine circuit integration feasibility. Variations in these parameters require circuit redesign and validation.

Environmental Compliance: Moisture sensitivity level (MSL 2A) and REACH status must be maintained or improved.

The MX3AWT-A1-0000-0009B7 shares identical mechanical, optical, and thermal specifications with the main part, enabling direct footprint compatibility. However, significant electrical parameter differences (3.7V Vf vs. 10.7V Vf; 350mA test current vs. 115mA test current) require circuit-level evaluation before substitution.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX3SWT-A1-0000-0009B7 is obsolete, while the MX3AWT-A1-0000-0009B7 is active. Active product status ensures ongoing availability and manufacturer support.

Compliance Advantage: The MX3AWT-A1-0000-0009B7 carries explicit RoHS Compliance certification, whereas RoHS status is not specified for the main part. Both components maintain REACH Unaffected status.

Electrical Parameter Divergence: The substitute part operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). These differences necessitate complete circuit redesign, including power supply reconfiguration, current limiting resistor recalculation, and thermal management reassessment. Luminous flux output remains equivalent (84lm), but efficiency differs marginally (65 lm/W vs. 68 lm/W).

Mechanical and Thermal Equivalence: Identical package geometry, dimensions, and thermal resistance enable direct PCB footprint compatibility without layout modification.

Selection of the MX3AWT-A1-0000-0009B7 is appropriate for new designs or redesigns where circuit-level electrical parameter changes are acceptable. For applications requiring preservation of the original 10.7V forward voltage characteristic, alternative suppliers or different LED series must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0009B7 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0009B7?

A: No. While both components share identical mechanical specifications (package type, dimensions, thermal resistance), the MX3AWT-A1-0000-0009B7 operates at 3.7V forward voltage compared to 10.7V for the main part. Direct substitution without circuit modification will result in component failure or malfunction. Power supply voltage, current limiting circuitry, and thermal design must be re-evaluated and modified.

Q: Are the luminous flux outputs equivalent between these parts?

A: Yes. Both components deliver 84lm (81lm ~ 87lm) at their respective test currents. However, the test currents differ significantly (115mA vs. 350mA), resulting in different power consumption profiles and thermal loads.

Q: What is the impact of the forward voltage difference on circuit design?

A: The 7V difference in forward voltage (10.7V vs. 3.7V) directly affects power supply requirements, current limiting resistor values, and overall circuit efficiency. Designs originally configured for 10.7V operation cannot accommodate the 3.7V part without complete electrical redesign.

Q: Are both components suitable for high-reliability applications?

A: Both components maintain identical Moisture Sensitivity Level (MSL 2A, 4 Weeks) and REACH Unaffected status. The MX3AWT-A1-0000-0009B7 carries explicit RoHS Compliance certification. Component selection should be based on compliance requirements specific to the application.

Q: What is the availability status of each component?

A: The MX3SWT-A1-0000-0009B7 is classified as obsolete with 1050 pieces in stock. The MX3AWT-A1-0000-0009B7 is active with 746 pieces in stock, ensuring ongoing availability and manufacturer support for future production requirements.
