Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-00607 is based on the following criteria:
Mechanical Compatibility: All substitute parts maintain identical package format (3529/9073 metric), footprint dimensions (9.00 mm × 7.00 mm), and mounting height (4.60 mm maximum), ensuring direct PCB compatibility without layout modifications.
Electrical Compatibility: Substitute parts operate at the same test current (350 mA), produce identical luminous flux at 25°C (65 lm, 62–67 lm range), and maintain 90° viewing angle. Forward voltage differs slightly (3.3V for XR-E series versus 4.6V for XR-C), which is within acceptable circuit design tolerance for LED applications using current-limiting resistors or constant-current drivers.
Performance Enhancement: XLamp® XR-E substitute parts deliver improved luminous efficacy (56 lm/W versus 53 lm/W) and superior thermal management (8°C/W versus 12°C/W), providing better heat dissipation and efficiency in equivalent form factors.
Product Status: All substitute parts carry active product status with RoHS compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance.

Engineering Selection Recommendations
All listed XLamp® XR-E substitute parts are qualified direct replacements for the obsolete XRCWHT-L1-0000-00607. Selection among substitute options is determined by color temperature requirements and application-specific needs:
XREWHT-L1-0000-00601 is suitable for applications requiring cool white color temperature (5000K–10000K range) with specified CRI of 75 typical. This part offers the broadest color temperature specification among available substitutes.
XREWHT-L1-0000-006B1, 006B2, 006B3, 006B4 are neutral white variants without specified color temperature or CRI data. These parts are appropriate for general-purpose white LED applications where color temperature is not critical.
XREWHT-L1-0000-006B5, 006B6, 006B7, 006B8, 006B9 are warm white variants without specified color temperature or CRI data. These parts are suitable for applications requiring warmer color appearance.
All substitute parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory alignment with the original part. The improved thermal resistance (8°C/W versus 12°C/W) and higher luminous efficacy (56 lm/W versus 53 lm/W) of XR-E series parts provide performance benefits in thermal-constrained designs.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-006B series parts be used as direct drop-in replacements for XRCWHT-L1-0000-00607?
A: Yes. All substitute parts share identical mechanical specifications (3529 package, 9.00 mm × 7.00 mm footprint, 4.60 mm seated height) and electrical performance (65 lm at 350 mA, 90° viewing angle). Forward voltage differs by 0.2V (3.3V versus 4.6V), which is accommodated by standard LED circuit designs using current-limiting resistors or constant-current drivers.
Q: What is the difference between XREWHT-L1-0000-00601 and the 006B series substitutes?
A: XREWHT-L1-0000-00601 specifies cool white color temperature (5000K–10000K) with CRI 75 typical. The 006B series variants (006B1–006B9) do not include color temperature or CRI specifications in the provided data. Selection depends on whether color temperature control is required for the application.
Q: Are there inventory considerations when selecting among substitute parts?
A: Yes. Inventory levels vary across substitute options. XREWHT-L1-0000-00601 has 1167 units in stock, while individual 006B variants range from 648 to 1056 units. Availability should be confirmed with the supplier for production quantities.
Q: Does the improved thermal resistance of XR-E parts affect circuit design?
A: The lower thermal resistance (8°C/W versus 12°C/W) of XR-E substitutes improves heat dissipation and junction temperature performance. This is a beneficial characteristic requiring no circuit modifications. Existing thermal designs will operate at lower junction temperatures with XR-E parts.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All listed XREWHT-L1-0000-006B series substitutes are supplied in Tape & Reel (TR) format, matching standard SMD assembly requirements.
