Key Parameters

Substitute Part Grouping Explanation

The XMLBWT-02-0000-000HT40F6 qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Identical color temperature (3750K warm white)
• Identical package form factor (2020 / 5050 Metric)
• Identical mounting type (Surface Mount SMD)
• Identical viewing angle (125°)
• Identical CRI rating (80)
• Identical maximum current rating (3A)
• Identical thermal resistance (2.5°C/W)
• Identical physical dimensions (5.00mm × 5.00mm × 3.15mm max height)
• Identical test current (700mA)
• Identical lumens/watt efficiency (123 lm/W)
• Identical compliance certifications (RoHS Compliant, REACH Unaffected)

Key Difference: The substitute represents an evolution within the XLamp® product line (XM-L2 generation) with a reduced forward voltage (2.72V vs. 2.9V), which improves power efficiency while maintaining identical optical and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The XMLBWT-02-0000-000HT40F6 is the appropriate substitute for the obsolete XMLAWT-02-0000-000HT40F6. Selection is justified on the following basis:

Product Status: The substitute is classified as Active, ensuring continued availability and supply chain support, whereas the main part is Obsolete.

Electrical Compatibility: Both parts operate at identical test current (700mA), maximum current (3A), and deliver equivalent luminous output (123 lm/W). The reduced forward voltage of the substitute (2.72V vs. 2.9V) represents an efficiency improvement and reduces power dissipation in the circuit, requiring no design modifications for standard current-limiting driver topologies.

Mechanical & Optical Compatibility: Identical package form factor, mounting type, viewing angle, and physical dimensions ensure direct PCB-level compatibility without layout or assembly changes.

Compliance & Certification: Both parts maintain identical RoHS Compliant and REACH Unaffected status, satisfying regulatory requirements for the same applications.

Thermal Performance: Identical thermal resistance (2.5°C/W) ensures equivalent thermal management characteristics in existing thermal designs.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-02-0000-000HT40F6 be used as a direct replacement without circuit modifications?

A: Yes. The substitute maintains identical test current, maximum current, viewing angle, CRI, and thermal resistance. The lower forward voltage (2.72V vs. 2.9V) is compatible with standard LED driver circuits and improves efficiency. No design changes are required.

Q: What is the significance of the forward voltage difference (2.9V vs. 2.72V)?

A: The reduced forward voltage in the substitute represents an improvement in LED efficiency. This results in lower power dissipation and reduced heat generation at the same test current. Existing current-limiting driver circuits will operate correctly with this lower voltage.

Q: Are the optical characteristics identical between the main part and substitute?

A: Yes. Both parts deliver 123 lm/W efficiency, maintain 80 CRI, and operate at 3750K color temperature. The viewing angle is identical at 125°. Luminous flux output is equivalent at the specified test current.

Q: Is the package form factor identical?

A: Yes. Both parts use the 2020 (5050 Metric) surface mount package with identical physical dimensions (5.00mm × 5.00mm) and maximum seated height (3.15mm). PCB footprints and assembly processes remain unchanged.

Q: What is the availability difference between these parts?

A: The main part (XMLAWT-02-0000-000HT40F6) is classified as Obsolete with 689 units in stock. The substitute (XMLBWT-02-0000-000HT40F6) is classified as Active with 810 units in stock, ensuring long-term supply chain availability.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are RoHS Compliant and REACH Unaffected, satisfying identical regulatory requirements for the same applications and markets.
