MX6SWT-H1-0000-000AA9 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-000AA9 is an XLamp® MX-6S warm white LED (2850K) designed for surface mount applications requiring high color rendering and directional light output. This part is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The MX-6S series has been superseded by the MX-6 series, which maintains compatibility across key electrical and mechanical parameters while offering improved performance characteristics and active product status.

Substitute Part Grouping Explanation

Substitution between MX6SWT-H1-0000-000AA9 and MX6AWT-H1-0000-000AA9 is permissible based on the following alignment of critical parameters:

Matching Parameters:

Color temperature: Both 2850K warm white
Color rendering index: Both CRI 80
Viewing angle: Both 120°
Package footprint: Both 5.00mm x 5.00mm, 2-SMD Gull Wing
Thermal resistance: Both 5°C/W
Moisture sensitivity: Both MSL 2A (4 Weeks)
Mounting type: Both surface mount

Differing Parameters: The MX6AWT-H1-0000-000AA9 operates at significantly different electrical specifications (3.3V forward voltage, 300mA test current) compared to the MX6SWT-H1-0000-000AA9 (20V forward voltage, 60mA test current). These differences require circuit-level evaluation and are not interchangeable without corresponding power supply and current-limiting modifications.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000AA9 is the designated successor to the obsolete MX6SWT-H1-0000-000AA9. Both parts maintain identical optical characteristics (2850K color temperature, CRI 80, 120° viewing angle) and mechanical compatibility (5.00mm footprint, 1.48mm height, 5°C/W thermal resistance).

The MX6AWT-H1-0000-000AA9 offers the following advantages:

Active product status with ongoing manufacturer support
RoHS compliance certification
Improved efficiency (92 lm/W versus 76 lm/W at respective test currents)
Higher maximum current rating (1A versus 175mA)

Direct substitution requires redesign of the power supply and current-limiting circuit due to the 20V-to-3.3V forward voltage reduction and corresponding increase in test current from 60mA to 300mA. The identical package footprint and thermal characteristics facilitate PCB-level compatibility once electrical modifications are implemented.

Frequently Asked Questions (FAQ)

Q: Can MX6AWT-H1-0000-000AA9 be used as a direct drop-in replacement for MX6SWT-H1-0000-000AA9?

A: No. While both parts share identical optical output (91lm at 2850K), viewing angle (120°), and physical footprint (5.00mm x 5.00mm), they operate at fundamentally different electrical specifications. The MX6SWT requires 20V forward voltage at 60mA, while the MX6AWT requires 3.3V at 300mA. Circuit redesign is mandatory.

Q: Are the package dimensions identical?

A: Yes. Both parts measure 5.00mm x 5.00mm with a maximum seated height of 1.48mm. The MX6AWT includes an exposed pad variant of the 2-SMD Gull Wing package, which may provide improved thermal performance in specific PCB layouts.

Q: What is the significance of the obsolete status of MX6SWT-H1-0000-000AA9?

A: Obsolete status indicates the manufacturer has discontinued production. The MX6AWT-H1-0000-000AA9 is the active replacement, ensuring long-term availability and manufacturer support for new designs and production continuity.

Q: Are compliance certifications equivalent between the two parts?

A: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99). The MX6AWT-H1-0000-000AA9 additionally carries RoHS compliance certification, providing enhanced regulatory alignment for applications subject to RoHS requirements.

Q: How do the thermal characteristics compare?

A: Thermal resistance is identical at 5°C/W for both parts. Moisture sensitivity levels are also equivalent (MSL 2A, 4 weeks). Thermal performance in application depends on PCB layout and thermal management design rather than inherent part differences.
