Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following parameters:

• Color and correlated color temperature (CCT) must match: White, Warm 2850K
• Package and case dimensions must be identical: 2020 (5050 Metric)
• Mounting type must be compatible: Surface Mount
• Viewing angle must be equal or greater: 125°
• CRI must be equal or greater: 80 (Typ)
• Forward voltage and test current must be within acceptable circuit design tolerances
• Thermal resistance must be equal or lower to ensure thermal compatibility

The XMLBWT-00-0000-000LT20F8 meets all substitution criteria. It maintains the same color temperature, package dimensions, mounting configuration, and optical specifications while offering improved efficiency and active product status.

Parameter Comparison

Engineering Selection Recommendations

The XMLBWT-00-0000-000LT20F8 is the direct substitute for the obsolete XMLAWT-00-0000-000LT20F8. Both parts are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for electronic component use.

The substitute offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Improved luminous efficiency (105 lm/W vs. 103 lm/W) reduces power consumption
• Lower forward voltage (2.72V vs. 2.9V) reduces circuit power dissipation
• Identical optical, thermal, and mechanical specifications ensure direct form-fit-function compatibility

No circuit redesign is required for substitution. The lower forward voltage of the XMLBWT variant may reduce thermal load in the application, providing a secondary benefit in thermal management.

Frequently Asked Questions (FAQ)

Q: Can the XMLBWT-00-0000-000LT20F8 be used as a direct replacement for the XMLAWT-00-0000-000LT20F8?

A: Yes. Both parts share identical color temperature (2850K), package dimensions (2020/5050 Metric), mounting type (Surface Mount), viewing angle (125°), CRI (80 Typ), and thermal resistance (2.5°C/W). The forward voltage difference (2.72V vs. 2.9V) is within acceptable design tolerances for most applications.

Q: What is the primary reason for substitution?

A: The XMLAWT-00-0000-000LT20F8 is classified as obsolete. The XMLBWT-00-0000-000LT20F8 is an active product from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both are 2020 (5050 Metric) surface mount packages with identical footprints and mounting requirements.

Q: Will the lower forward voltage of the substitute affect circuit performance?

A: No. The 0.18V reduction in forward voltage (2.9V to 2.72V) is within normal design tolerances. This may reduce power dissipation in series resistor networks or current-limiting circuits, providing a thermal benefit.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the XMLAWT-00-0000-000LT20F8 and XMLBWT-00-0000-000LT20F8 are RoHS Compliant and REACH Unaffected.
