Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-000AA9 is determined by the following critical parameters:

Color and CCT matching: Both parts must maintain White, Warm 2850K specification to preserve color temperature consistency in lighting applications.

Mechanical compatibility: Package type (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00mm x 5.00mm), and height (1.48mm max) must remain identical to ensure PCB layout and assembly compatibility.

Optical characteristics: Viewing angle (120°) and CRI (80 Typ) must be maintained for consistent light distribution and color rendering.

Electrical operating range: Forward voltage and current ratings must be compatible with existing circuit designs. The substitute part may operate at different nominal current levels provided the application circuit can accommodate the electrical characteristics.

The MX3AWT-A1-0000-000AA9 qualifies as a substitute based on these parameters, though with electrical characteristic differences that require circuit evaluation.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AA9 is available as an active product with RoHS compliance certification, providing supply chain continuity for the obsolete MX3SWT-A1-0000-000AA9. Both parts share identical mechanical packaging, optical characteristics (viewing angle, CRI), and color temperature specification (2850K warm white).

The primary design consideration is the significant difference in electrical characteristics: the substitute operates at 3.7V typical forward voltage and 350mA test current, compared to 10.7V and 115mA for the main part. This represents a fundamental difference in LED architecture between the MX-3 and MX-3S series. Circuit redesign or power supply modification is required to accommodate the MX3AWT-A1-0000-000AA9 in applications originally designed for the MX3SWT-A1-0000-000AA9.

Both parts maintain identical thermal resistance (11°C/W) and moisture sensitivity level (2A, 4 Weeks), supporting equivalent thermal management and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AA9 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AA9?

A: No. While both parts share identical mechanical packaging and optical specifications, the forward voltage differs significantly (3.7V vs. 10.7V). Direct substitution without circuit modification will result in incorrect LED operation or failure. The application circuit must be redesigned to accommodate the lower voltage and higher current requirements of the MX3AWT-A1-0000-000AA9.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts use 2-SMD Gull Wing Exposed Pad packaging with identical dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm). PCB layout and assembly tooling remain compatible.

Q: Do both parts meet the same color temperature specification?

A: Yes. Both the MX3SWT-A1-0000-000AA9 and MX3AWT-A1-0000-000AA9 operate at 2850K warm white color temperature with 80 CRI (typical), ensuring consistent color rendering in lighting applications.

Q: What is the impact of the different test currents on luminous flux output?

A: Both parts deliver 91lm (87lm ~ 94lm) at their respective test currents (115mA and 350mA). The luminous flux specification is identical; however, the efficiency differs slightly (74 lm/W vs. 70 lm/W), reflecting the different LED architectures of the MX-3S and MX-3 series.

Q: Is the MX3AWT-A1-0000-000AA9 RoHS compliant?

A: Yes. The MX3AWT-A1-0000-000AA9 carries RoHS Compliant certification. RoHS status for the obsolete MX3SWT-A1-0000-000AA9 is not specified in available documentation.

Q: Are moisture sensitivity and thermal management requirements the same?

A: Yes. Both parts share identical MSL rating (2A, 4 Weeks) and thermal resistance (11°C/W), supporting equivalent handling, storage, and thermal design considerations.
