Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AA5 is based on the following critical parameters:

Electrical Compatibility Criteria:

• Color and CCT matching (White, Warm 3750K)
• Flux output range (87lm ~ 94lm @ 25°C)
• CRI rating (80 Typ)
• Viewing angle (120°)

Mechanical Compatibility Criteria:

• Package type (2-SMD, Gull Wing Exposed Pad)
• Physical dimensions (5.00mm x 5.00mm footprint)
• Height constraint (1.48mm max)
• Thermal resistance (11°C/W)

Operational Constraints:

• Surface mount mounting type
• MSL rating (2A, 4 Weeks)

The MX3AWT-A1-0000-000AA5 qualifies as a substitute based on matching color, CCT, flux output, CRI, viewing angle, package type, physical dimensions, height, thermal resistance, and MSL rating. Differences in forward voltage and test current reflect the distinct electrical design of the MX-3 series versus the MX-3S series, but these do not preclude substitution when circuit design accommodates the different voltage and current specifications.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AA5 is the designated substitute for the obsolete MX3SWT-A1-0000-000AA5. Selection is supported by the following factors:

Product Status: The substitute part carries Active status, ensuring continued availability and supply chain reliability compared to the Obsolete main part.

Compliance & Certifications: The MX3AWT-A1-0000-000AA5 is RoHS Compliant, whereas RoHS status is not specified for the main part. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Optical & Thermal Equivalence: Both parts deliver identical flux output (91lm, 87lm ~ 94lm range), CRI (80 Typ), and viewing angle (120°). Thermal resistance is identical at 11°C/W, ensuring equivalent thermal management performance.

Mechanical Compatibility: Identical package type, footprint dimensions (5.00mm x 5.00mm), and maximum height (1.48mm) confirm direct PCB compatibility without layout modifications.

Electrical Differences: The substitute operates at 3.7V forward voltage with 350mA test current, compared to 10.7V and 115mA for the main part. Circuit design must accommodate these electrical differences. The substitute delivers 70 lm/W versus 74 lm/W for the main part, representing a 4 lm/W efficiency difference.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AA5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AA5?

A: Mechanical and optical compatibility is confirmed. However, the substitute requires circuit redesign due to different forward voltage (3.7V vs. 10.7V) and test current (350mA vs. 115mA) specifications. PCB footprint and thermal characteristics remain identical.

Q: What are the key differences between the MX-3S and MX-3 series?

A: The primary differences are forward voltage and operating current. The MX-3S operates at higher voltage (10.7V) with lower current (115mA), while the MX-3 operates at lower voltage (3.7V) with higher current (350mA). Both deliver equivalent optical output and thermal performance.

Q: Are there any compliance or regulatory differences?

A: The substitute part is explicitly RoHS Compliant, while RoHS status is not specified for the main part. Both maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Q: Does the substitute part have the same package and footprint?

A: Yes. Both parts use 2-SMD Gull Wing Exposed Pad packaging with identical 5.00mm x 5.00mm footprint and 1.48mm maximum height. No PCB layout modifications are required for mechanical fit.

Q: What is the impact of the 4 lm/W efficiency difference?

A: The substitute delivers 70 lm/W compared to 74 lm/W for the main part. At equivalent flux output (91lm), this represents a 4% efficiency difference. Power consumption will be proportionally higher in the substitute design.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 2A (4 Weeks) rating, requiring identical handling and storage protocols.
