Engineering Selection Recommendations

All listed XLamp® XR-E substitute parts maintain active product status with CreeLED, Inc., ensuring long-term supply chain availability and technical support. The substitute parts are RoHS Compliant and REACH Unaffected, matching the regulatory compliance profile of the original XRCWHT-L1-0000-00609.

The XLamp® XR-E series substitutes deliver improved thermal performance with 8°C/W thermal resistance compared to the original 12°C/W specification, resulting in lower junction temperatures during operation. All substitutes maintain identical package dimensions, mounting interface, and luminous flux output at 350mA test current, ensuring direct form-fit-function compatibility.

The forward voltage reduction from 4.6V to 3.3V in the XR-E series results in lower power dissipation and improved efficiency (56 lm/W versus 53 lm/W). Circuit designs operating at fixed current sources require no modification. Designs using series resistors for current limiting will experience slightly reduced current draw, which is within acceptable tolerance for LED lighting applications.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006B1 through XREWHT-L1-0000-006B9 be used interchangeably with XRCWHT-L1-0000-00609?

A: Yes. All substitute parts share identical package dimensions (3529 / 9073 Metric), mounting type (Surface Mount), viewing angle (90°), and luminous flux output (65lm at 350mA). The 3529 package footprint is identical across all parts, enabling direct PCB assembly compatibility without layout modifications.

Q: What is the difference between XREWHT-L1-0000-00601 and the other XR-E substitutes?

A: XREWHT-L1-0000-00601 specifies a color temperature range of 5000K to 10000K (Cool White), while XREWHT-L1-0000-006B1 through XREWHT-L1-0000-006B9 are specified as White without explicit CCT designation. All parts maintain identical electrical parameters and package specifications. Selection depends on application color temperature requirements.

Q: Will the lower forward voltage (3.3V vs 4.6V) affect circuit operation?

A: For current-source driven designs, the voltage difference has no functional impact. For resistor-based current limiting circuits, the 0.2V reduction results in slightly lower current draw. At 350mA nominal operation, this represents approximately 5.7% reduction in power dissipation, which is beneficial for thermal management.

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

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original XRCWHT-L1-0000-00609 packaging format is not specified in the provided data. Confirm packaging requirements with your procurement specification before ordering.

Q: What is the inventory status for substitute parts?

A: XREWHT-L1-0000-00601 has 1167 units in stock. XREWHT-L1-0000-006B1 through XREWHT-L1-0000-006B9 have inventory ranging from 648 to 1056 units. All parts are classified as New Original In Stock.

Q: Do the substitute parts require different handling procedures?

A: No. All substitute parts maintain identical Moisture Sensitivity Level (MSL 4, 72 Hours) and REACH compliance status. Existing component handling, storage, and assembly procedures remain unchanged.
