Engineering Selection Recommendations

All listed substitute parts are active production components from CreeLED's XLamp® XR-E series. The XLamp® XR-E series maintains full mechanical and electrical compatibility with the obsolete XLamp® XR-C series while providing improved thermal characteristics (8°C/W vs. 12°C/W) and enhanced luminous efficiency (67 lm/W vs. 63 lm/W).

All substitute parts maintain RoHS Compliance and identical Moisture Sensitivity Level (MSL) 4 specifications. REACH Unaffected status is consistent across all parts. The forward voltage differential (3.3V vs. 4.6V nominal) is within acceptable operating tolerances for standard LED driver circuits designed for white LED applications.

The substitute parts are available in Tape & Reel (TR) packaging format, suitable for automated assembly processes. Inventory availability ranges from 663 to 1,083 pieces across the substitute part options.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008B1 through XREWHT-L1-0000-008B9 be used as direct replacements for XRCWHT-L1-0000-00810?

A: Yes. All substitute parts share identical mechanical dimensions, package format, viewing angle, luminous flux output at rated current, and test current specifications. The 0.2V forward voltage reduction (4.6V to 3.3V) is within standard operating tolerances for LED driver circuits.

Q: What is the difference between XREWHT-L1-0000-00801 and the other XR-E substitutes?

A: XREWHT-L1-0000-00801 is specified with a color temperature range of 5000K–10000K (Cool White), while XREWHT-L1-0000-008B1 through 008B9 are specified as neutral or warm white variants. All maintain identical electrical and mechanical parameters for substitution purposes.

Q: Are there packaging differences between the main part and substitutes?

A: The main part XRCWHT-L1-0000-00810 is supplied in standard packaging format. Substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. The component itself maintains identical physical dimensions and footprint.

Q: What is the thermal performance improvement of the XR-E series?

A: The XLamp® XR-E series provides improved thermal resistance of 8°C/W compared to the XLamp® XR-C series at 12°C/W. This 33% reduction in thermal resistance results in lower junction temperatures under identical operating conditions, extending component lifespan and improving reliability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS Compliance status and REACH Unaffected classification, consistent with the original XRCWHT-L1-0000-00810 specifications.
