Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEBWT-L1-0000-00DF4 is determined by strict equivalence in the following critical parameters:

• Series Compatibility: Both parts must belong to the XLamp® XP-E2 series
• Electrical Equivalence: Forward voltage (Vf) of 2.9V, test current of 350mA, and maximum current rating of 1A must be maintained
• Optical Performance: Flux output at 85°C test current (111lm ± 3lm range), lumens/watt efficiency (109 lm/W), and CRI (75 Typ) must be equivalent
• Mechanical Compatibility: Package type 1414 (3535 Metric), viewing angle of 110°, and thermal resistance of 9°C/W must match
• Regulatory Compliance: RoHS Compliant and REACH Unaffected status must be maintained
• Color Temperature Tolerance: Neutral white color category with CCT within the 4500K–4750K range

The XPEBWT-L1-0000-00DE4 qualifies as a parametric equivalent substitute, differing only in CCT specification (4500K vs. 4750K), which remains within the neutral white category and maintains all other electrical, optical, and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the XPEBWT-L1-0000-00DF4 and XPEBWT-L1-0000-00DE4 are active products from CreeLED, Inc., with identical RoHS Compliant and REACH Unaffected certifications. Selection between these parts is based on color temperature requirement within the neutral white category. The XPEBWT-L1-0000-00DF4 operates at 4750K, while the XPEBWT-L1-0000-00DE4 operates at 4500K. All other electrical, optical, mechanical, and thermal specifications are equivalent. Component selection should be determined by the specific CCT requirement of the application. Both parts maintain identical forward voltage, current ratings, flux output, efficiency, CRI, viewing angle, package dimensions, and thermal characteristics, ensuring direct substitution capability within the XLamp® XP-E2 series.

Frequently Asked Questions (FAQ)

Q: Can XPEBWT-L1-0000-00DE4 be used as a direct replacement for XPEBWT-L1-0000-00DF4?

A: Yes, the XPEBWT-L1-0000-00DE4 is a parametric equivalent substitute. All electrical, optical, mechanical, and thermal parameters are identical. The only difference is the color temperature: 4500K (XPEBWT-L1-0000-00DE4) versus 4750K (XPEBWT-L1-0000-00DF4). Both are neutral white LEDs within the same series and package.

Q: Are there any differences in forward voltage or current ratings between these parts?

A: No. Both parts have identical forward voltage (2.9V typical), test current (350mA), and maximum current rating (1A). They are electrically equivalent.

Q: Do both parts use the same package and mounting footprint?

A: Yes. Both parts use the 1414 (3535 Metric) surface mount package with identical dimensions (0.136" L x 0.136" W / 3.45mm x 3.45mm) and maximum seated height (0.094" / 2.39mm). They are mechanically interchangeable.

Q: What is the difference between 4750K and 4500K color temperature?

A: Both are neutral white color temperatures. The 4750K variant (XPEBWT-L1-0000-00DF4) is slightly warmer than the 4500K variant (XPEBWT-L1-0000-00DE4). Selection depends on the specific color temperature requirement of the application.

Q: Are both parts RoHS compliant?

A: Yes. Both XPEBWT-L1-0000-00DF4 and XPEBWT-L1-0000-00DE4 are RoHS Compliant and REACH Unaffected.

Q: What is the thermal resistance of these LEDs?

A: Both parts have a thermal resistance of 9°C/W, ensuring identical thermal performance in circuit design.

Q: Do these parts have the same luminous flux output?

A: Yes. Both parts deliver 111lm (107lm – 114lm range) at 85°C test current and maintain 109 lm/W efficiency at the 350mA test current.
