Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AA1 is based on the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must maintain cool white 5000K specification for color consistency in lighting applications.
• Package and Mechanical Compatibility: Both parts use identical 2-SMD, Gull Wing Exposed Pad configuration with 5.00mm × 5.00mm footprint and 1.48mm maximum seated height, ensuring PCB layout compatibility.
• Thermal Characteristics: Thermal resistance of 11°C/W is maintained across both parts.
• Viewing Angle: 120° viewing angle is preserved for optical consistency.
• Moisture Sensitivity: Both parts share MSL 2A (4 Weeks) classification.

The MX3AWT-A1-R250-000BE3 qualifies as a substitute despite differences in forward voltage and current specifications, as these parameters are application-dependent and do not preclude functional equivalence in appropriately designed circuits. The substitute part is active in production status, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-R250-000BE3 is the designated substitute for the obsolete MX3SWT-A1-0000-000AA1. Selection is justified on the following basis:

• Product Status: The substitute part is active in production, ensuring long-term availability and supply chain continuity.
• Compliance: The MX3AWT-A1-R250-000BE3 carries RoHS Compliant certification, meeting current regulatory requirements. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.
• Mechanical Compatibility: Identical package footprint, dimensions, and thermal characteristics ensure direct PCB compatibility without layout modifications.
• Optical and Color Specifications: Matching 5000K CCT, 120° viewing angle, and CRI of 75 (Typ) preserve color rendering and light distribution characteristics.
• Electrical Redesign Requirement: The significant difference in forward voltage (10.7V vs. 3.7V) and test current (115mA vs. 350mA) necessitates circuit redesign. Power supply and current-limiting circuitry must be recalculated to accommodate the lower voltage and higher current characteristics of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-R250-000BE3 be used as a direct drop-in replacement without circuit modifications?

A: No. While the package and mechanical specifications are identical, the forward voltage and current ratings differ significantly. The substitute part operates at 3.7V typical versus 10.7V for the original, requiring redesign of power supply and current-limiting circuits. Direct substitution without electrical redesign will result in component failure or inadequate performance.

Q: Are the color and light output characteristics equivalent?

A: Yes, for practical lighting applications. Both parts maintain 5000K cool white color temperature with CRI of 75 (Typ). The substitute part provides slightly higher luminous flux (97lm vs. 91lm) and equivalent lumens per watt efficiency (75 vs. 74 lm/W), making it suitable for applications requiring cool white illumination.

Q: What is the impact of the different current ratings?

A: The MX3AWT-A1-R250-000BE3 operates at higher current (350mA test, 500mA maximum) compared to the original (115mA test, 175mA maximum). This requires power supply and thermal management recalculation. Higher current operation may necessitate improved PCB thermal design and current distribution to maintain reliability.

Q: Are there packaging or moisture sensitivity differences?

A: No. Both parts use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00mm × 5.00mm footprint and 1.48mm maximum height. Moisture sensitivity level is 2A (4 Weeks) for both parts, requiring identical handling and storage protocols.

Q: What is the significance of the RoHS Compliant status on the substitute part?

A: The MX3AWT-A1-R250-000BE3 carries RoHS Compliant certification, meeting current environmental and regulatory requirements for lead-free manufacturing. This is advantageous for new designs and markets with RoHS mandates. The original part's RoHS status is not specified, which may reflect its obsolete classification.
