Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AA4 is based on the following critical parameters:

Optical Compatibility: Color temperature (4000K neutral white) and CRI (80 Typ) must match to maintain color consistency in end-use applications.

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00 mm × 5.00 mm), and height (1.48 mm max) must be identical to ensure PCB assembly compatibility without design modification.

Electrical Compatibility: Forward voltage, test current, and maximum current ratings determine circuit design feasibility. Substitutes must operate within the same voltage and current envelope or require circuit redesign.

Luminous Output: Flux output at 25°C (91 lm nominal) establishes brightness equivalence for optical performance.

The identified substitute, MX6AWT-A1-0000-000AE5, shares identical optical (4000K, 80 CRI, 91 lm), mechanical (5.00 mm × 5.00 mm, 1.48 mm height, 2-SMD package), and viewing angle (120°) specifications. However, electrical parameters differ significantly: the MX-6 operates at 3.3V / 300mA versus the MX-3S at 10.7V / 115mA, requiring circuit redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000AE5 provides optical and mechanical equivalence to the obsolete MX3SWT-A1-0000-000AA4, with identical color temperature (4000K), CRI (80), luminous flux (91 lm), viewing angle (120°), and physical footprint (5.00 mm × 5.00 mm, 1.48 mm height).

Active Product Status: The MX-6 is classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete MX-3S.

Compliance Advantage: The MX6AWT-A1-0000-000AE5 carries RoHS Compliant certification, whereas RoHS status is not specified for the MX-3S. This provides regulatory compliance assurance for new designs.

Electrical Redesign Required: Direct pin-for-pin substitution is not possible. The MX-6 operates at 3.3V / 300mA versus the MX-3S at 10.7V / 115mA. Circuit redesign of the LED driver and current-limiting network is mandatory. The MX-6 exhibits superior efficiency (92 lm/W versus 74 lm/W) and lower thermal resistance (5°C/W versus 11°C/W), providing thermal performance benefits in the redesigned circuit.

Packaging Compatibility: Both parts use identical 2-SMD, Gull Wing Exposed Pad packages with matching footprints and heights, eliminating PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000AE5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AA4?

A: No. While both parts share identical optical output (91 lm, 4000K, 80 CRI), viewing angle (120°), and mechanical footprint (5.00 mm × 5.00 mm, 1.48 mm height), the electrical specifications differ fundamentally. The MX-3S requires 10.7V at 115mA, while the MX-6 operates at 3.3V at 300mA. Circuit redesign of the LED driver is required.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both the MX3SWT-A1-0000-000AA4 and MX6AWT-A1-0000-000AE5 use the 2-SMD, Gull Wing Exposed Pad package with identical dimensions (5.00 mm × 5.00 mm) and seated height (1.48 mm max). No PCB layout modifications are necessary.

Q: What is the key difference in electrical operation between these parts?

A: The MX-3S operates at higher voltage (10.7V) with lower current (115mA test), while the MX-6 operates at lower voltage (3.3V) with higher current (300mA test). This difference requires redesign of the current-limiting resistor or active LED driver circuit. The MX-6 achieves higher efficiency (92 lm/W versus 74 lm/W).

Q: Will the optical output be identical in my application?

A: Yes, for equivalent operating conditions. Both parts produce 91 lm nominal flux at 25°C with 80 CRI and 4000K color temperature. However, the MX-6 must be operated at its specified 300mA test current to achieve this output, whereas the MX-3S was rated at 115mA. Ensure your redesigned circuit delivers the correct current to each part.

Q: Is the MX6AWT-A1-0000-000AE5 more thermally efficient?

A: Yes. The MX-6 has thermal resistance of 5°C/W compared to 11°C/W for the MX-3S, indicating superior heat dissipation characteristics. This provides thermal performance benefits in applications with thermal constraints.

Q: What is the availability status difference between these parts?

A: The MX3SWT-A1-0000-000AA4 is obsolete, limiting future availability. The MX6AWT-A1-0000-000AE5 is active, ensuring long-term supply chain continuity and design support from the manufacturer.

Q: Does the MX-6 meet RoHS compliance requirements?

A: Yes. The MX6AWT-A1-0000-000AE5 is RoHS Compliant. RoHS status is not specified for the obsolete MX-3S. For new designs subject to RoHS regulations, the MX-6 provides documented compliance.
