Primary Substitute: XREWHT-L1-0000-00601 is the direct functional equivalent, offering cool white color temperature (5000K–10000K) matching the original part's cool white specification. This part provides improved efficiency (56 lm/W vs. 53 lm/W) and superior thermal performance (8°C/W vs. 12°C/W) while maintaining identical luminous output at the standard 350 mA test current.
Alternative Substitutes: Parts XREWHT-L1-0000-006B1 through XREWHT-L1-0000-006B9 are parametric equivalents with identical electrical and optical performance at 350 mA operation. These parts differ in color temperature binning (neutral white and warm white variants) but maintain the same luminous flux, forward voltage, viewing angle, and package configuration. Selection among these alternatives depends on the specific color temperature requirement of the application.
All substitute parts carry RoHS Compliant and REACH Unaffected certifications, maintaining regulatory compliance with the original part. Moisture sensitivity level remains constant at MSL 4 (72 Hours), requiring identical handling and storage protocols.

The improved thermal resistance (8°C/W vs. 12°C/W) of the substitute part provides enhanced thermal performance without requiring thermal management modifications.
Q: Do the substitute parts have the same moisture sensitivity requirements?
A: Yes. All substitute parts carry MSL 4 (72 Hours) rating, identical to the original part. Handling, storage, and reflow soldering protocols remain unchanged. Parts must be stored in dry conditions and used within 72 hours of moisture barrier bag opening.
Q: What is the inventory status of these substitute parts?
A: XREWHT-L1-0000-00601 has 1,167 units in stock. Alternative parts XREWHT-L1-0000-006B1 through XREWHT-L1-0000-006B9 have inventory ranging from 648 to 1,056 units, providing multiple sourcing options for production requirements.
Q: Are all substitute parts RoHS and REACH compliant?
A: Yes. All listed substitute parts are RoHS Compliant and REACH Unaffected, maintaining full regulatory alignment with the original XRCWHT-L1-0000-00608 part.
