Matching Parameters:

Color and CCT: White, Warm 3250K (identical)
Flux output: 91lm at 25°C (identical specification range)
CRI: 80 (identical)
Viewing angle: 120° (identical)
Physical footprint: 5.00mm x 5.00mm (identical)
Height: 1.48mm maximum (identical)
Thermal resistance: 5°C/W (identical)
Mounting type: Surface mount, 2-SMD Gull Wing configuration
MSL rating: 2A (4 Weeks) (identical)

Allowable Variations:

Forward voltage and current characteristics differ due to series evolution (MX-6S to MX-6)
Packaging format may vary (Tape & Reel vs. standard packaging)
Product status transition from obsolete to active

The MX6AWT-H1-0000-000AA7 qualifies as a direct substitute based on maintained optical, thermal, and mechanical specifications, despite electrical parameter differences inherent to the generational upgrade.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000AA7 is the qualified substitute for the obsolete MX6SWT-H1-0000-000AA7 based on the following factors:

Product Status: The substitute part maintains active product status with CreeLED, Inc., ensuring continued availability and supply chain reliability compared to the obsolete main part.

Compliance: The MX6AWT-H1-0000-000AA7 carries RoHS Compliant certification, providing regulatory advantage for applications subject to RoHS requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Optical Equivalence: Identical color temperature (3250K), flux output (91lm), CRI (80), and viewing angle (120°) ensure optical performance parity in end-use applications.

Thermal and Mechanical Compatibility: Matching thermal resistance (5°C/W), physical dimensions (5.00mm x 5.00mm), and height (1.48mm) confirm direct mechanical interchangeability in existing PCB layouts.

Electrical Differences: The substitute operates at 3.3V with 300mA test current versus 20V at 60mA for the main part. Circuit design modifications are required to accommodate these electrical parameter changes. The substitute demonstrates improved efficiency (92 lm/W vs. 76 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AA7 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000AA7?

A: Mechanical and optical compatibility is confirmed. However, electrical circuit modifications are mandatory due to the significant difference in forward voltage (3.3V vs. 20V) and test current (300mA vs. 60mA). PCB layout remains compatible, but power supply and current limiting circuits must be redesigned.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching color temperature (3250K), luminous flux (91lm), CRI (80), viewing angle (120°), thermal resistance (5°C/W), and physical dimensions (5.00mm x 5.00mm x 1.48mm height). These parameters ensure optical and thermal performance equivalence.

Q: Does the packaging format difference affect compatibility?

A: The main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel format is standard for high-volume production.

Q: Is the substitute part RoHS compliant?

A: Yes, the MX6AWT-H1-0000-000AA7 is RoHS Compliant. The main part's RoHS status is not specified in the provided data.

Q: What is the impact of the efficiency improvement in the substitute part?

A: The substitute achieves 92 lm/W compared to 76 lm/W for the main part at their respective test currents. This reflects generational improvement in the MX-6 series design but does not affect substitution eligibility, which is based on matching optical output (91lm) and thermal characteristics.

Q: Are both parts subject to the same moisture sensitivity requirements?

A: Yes, both parts carry MSL rating 2A (4 Weeks), indicating identical moisture sensitivity handling requirements during storage and assembly.
