Substitute Part Grouping Explanation

Substitute parts for the XTEAWT-02-0000-00000LEF4 are identified based on the following allowed electrical and mechanical parameters:

• Package / Case: 1414 (3535 Metric) — identical footprint and mounting compatibility
• Mounting Type: Surface Mount — same assembly process
• Color: White, Neutral — consistent color family
• Current - Test: 350mA — matching test current specification
• CRI (Color Rendering Index): 75 (Typ) — equivalent color rendering performance
• Flux @ 85°C, Current - Test: 118lm (114lm ~ 122lm) — equivalent luminous flux output
• Lumens/Watt @ Current - Test: 116–118 lm/W — comparable luminous efficacy
• RoHS Status: RoHS Compliant — regulatory alignment
• REACH Status: REACH Unaffected — regulatory alignment

The substitute parts XPEBWT-L1-0000-00EE4 and XPEBWT-L1-0000-00EE5 meet these criteria. Variations in CCT (Correlated Color Temperature) and forward voltage (Vf) are within acceptable ranges for neutral white LED applications and do not preclude substitution in circuits designed for the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—XTEAWT-02-0000-00000LEF4, XPEBWT-L1-0000-00EE4, and XPEBWT-L1-0000-00EE5—carry Active product status and are RoHS Compliant with REACH Unaffected designation. This ensures regulatory compliance and long-term availability support.

The primary part (XTEAWT-02-0000-00000LEF4) offers superior thermal performance (5°C/W vs. 9°C/W) and higher maximum current rating (1.5A vs. 1A), making it the preferred choice for high-power or thermally constrained applications. The substitute parts (XPEBWT-L1-0000-00EE4 and XPEBWT-L1-0000-00EE5) provide equivalent luminous flux and efficacy at the 350mA test current, with slightly lower forward voltage and reduced thermal resistance. Selection between XPEBWT-L1-0000-00EE4 (4500K) and XPEBWT-L1-0000-00EE5 (4000K) depends on the specific CCT requirement of the application.

Frequently Asked Questions (FAQ)

Q: Can XPEBWT-L1-0000-00EE4 or XPEBWT-L1-0000-00EE5 be used as direct replacements for XTEAWT-02-0000-00000LEF4?

A: Yes, both substitute parts share identical package geometry (1414 / 3535 Metric), mounting type (Surface Mount), test current (350mA), luminous flux (118lm @ 85°C), and CRI (75 Typ). They are electrically and mechanically compatible for direct PCB substitution. However, the lower maximum current rating (1A vs. 1.5A) and higher thermal resistance (9°C/W vs. 5°C/W) of the substitutes must be evaluated against circuit design requirements.

Q: What are the differences in CCT between the primary part and substitutes?

A: The primary part operates at 4750K (neutral white). XPEBWT-L1-0000-00EE4 operates at 4500K, and XPEBWT-L1-0000-00EE5 operates at 4000K. All three fall within the neutral white color family. CCT selection depends on the application's color temperature specification. If the application requires 4750K specifically, the primary part is the correct choice.

Q: Are there differences in forward voltage between these parts?

A: The primary part has a typical forward voltage (Vf) of 2.85V, while both substitutes have 2.9V. This 0.05V difference is within typical LED tolerance ranges and should not significantly impact circuit performance in properly designed current-limiting driver circuits.

Q: What is the significance of the thermal resistance difference?

A: The primary part (XTEAWT-02-0000-00000LEF4) has a thermal resistance of 5°C/W, while the substitutes have 9°C/W. Lower thermal resistance indicates better heat dissipation from the LED junction to the package. In high-power or thermally constrained applications, the primary part's superior thermal performance may be necessary to maintain junction temperature within safe operating limits.

Q: Can I operate the substitute parts at higher currents than 350mA?

A: The substitute parts have a maximum current rating of 1A, compared to 1.5A for the primary part. Operation above 350mA is possible up to the 1A maximum, but thermal management becomes increasingly critical due to the higher thermal resistance (9°C/W). The primary part's 1.5A maximum rating and lower thermal resistance make it more suitable for high-current applications.

Q: Are all three parts available in the same packaging format?

A: Yes, all three parts are supplied in Tape & Reel (TR) packaging, enabling compatibility with standard automated assembly processes.

Q: Do all parts meet the same regulatory requirements?

A: Yes, all three parts are RoHS Compliant and REACH Unaffected, ensuring compliance with current environmental and chemical regulations.
