Substitute Part Grouping Explanation
Substitution of the XRCWHT-L1-0000-005F7 is based on the following criteria:
Mechanical Compatibility: All substitute parts maintain identical package dimensions (3529 / 9073 Metric), mounting type (Surface Mount), and physical footprint (0.354" L x 0.276" W, 4.60mm max height), ensuring direct PCB compatibility without layout modifications.
Optical Compatibility: All substitutes maintain the same viewing angle (90°) and CRI (80 Typ), preserving optical performance characteristics.
Electrical Operating Point: All substitutes are rated for 350mA test current with identical flux output (59lm at 25°C), ensuring equivalent luminous intensity at the standard operating point.
Series Transition: The primary substitutes belong to the XLamp® XR-E series, which represents the active production equivalent to the obsolete XLamp® XR-C series. XR-E parts offer improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current ratings (700mA vs. 500mA).
Color Temperature Variants: Substitutes are available in four color temperature options (2700K, 2900K, 3000K, 3200K) to match application requirements. The 3200K variants (XREWHT-L1-0000-005F7 and XREWHT-L1-R250-005F7) provide the closest spectral match to the original part.
Packaging Options: Substitutes are available in both bulk and Tape & Reel (TR) packaging configurations, with the R250 designation indicating reel packaging.

Engineering Selection Recommendations
Primary Substitute (Exact Color Temperature Match): XREWHT-L1-0000-005F7 or XREWHT-L1-R250-005F7 are the direct functional equivalents, maintaining the 3200K color temperature of the original XRCWHT-L1-0000-005F7. Both parts are active production items from CreeLED with identical optical and electrical performance at the 350mA test point. Selection between bulk and Tape & Reel packaging depends on assembly process requirements.
Alternative Color Temperature Options: If application requirements permit color temperature flexibility, XREWHT-L1-0000-005E7 (3000K) and XREWHT-L1-0000-005F8 (2900K) provide equivalent luminous output and thermal performance. These alternatives are suitable for warm white lighting applications where exact color temperature matching is not critical.
Compliance and Regulatory: All substitute parts maintain RoHS Compliance, REACH Unaffected status, and identical MSL (4, 72 Hours) ratings, ensuring compatibility with existing supply chain and manufacturing processes.
Thermal Performance Improvement: XLamp® XR-E substitutes offer superior thermal characteristics (8°C/W vs. 12°C/W), enabling improved thermal management in high-density applications and supporting higher maximum current ratings (700mA vs. 500mA) for future design flexibility.
Forward Voltage Consideration: Substitute parts operate at 3.3V typical forward voltage compared to 4.6V for the original part. Circuit designs must accommodate this 0.2V reduction in forward voltage drop. At the standard 350mA test current, all parts deliver identical luminous flux (59lm), confirming electrical compatibility at the design operating point.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-005F7 be used as a direct replacement for XRCWHT-L1-0000-005F7 without circuit modifications?
A: Yes. Both parts maintain identical mechanical footprint (3529 package), viewing angle (90°), and luminous output (59lm at 350mA). The 0.2V reduction in forward voltage (4.6V to 3.3V) is within typical circuit design tolerances for LED applications. Existing current-limiting circuits will function correctly with the substitute part.
Q: What is the difference between bulk packaging and Tape & Reel (TR) packaging options?
A: Bulk packaging (XREWHT-L1-0000-005F7) is suitable for manual assembly or small-volume production. Tape & Reel packaging (XREWHT-L1-R250-005F7) is optimized for automated pick-and-place assembly equipment, with the R250 designation indicating 250-unit reel configuration. Packaging selection depends on manufacturing process and volume requirements.
Q: Are all substitute parts RoHS compliant and REACH compliant?
A: All substitute parts are RoHS Compliant and REACH Unaffected, matching the compliance status of the original XRCWHT-L1-0000-005F7. No additional regulatory documentation or supply chain modifications are required.
Q: What is the significance of the improved thermal resistance (8°C/W vs. 12°C/W) in XR-E substitutes?
A: Lower thermal resistance improves heat dissipation from the LED junction to the PCB, resulting in lower junction temperatures during operation. This enables higher current operation (700mA maximum vs. 500mA) and extends LED lifespan in thermally constrained applications.
Q: Can I substitute a 2700K or 3000K part if the original design specifies 3200K?
A: Color temperature substitution is application-dependent. If the design requires precise 3200K color rendering for color-critical applications, use XREWHT-L1-0000-005F7 or XREWHT-L1-R250-005F7. For general warm white lighting where color temperature tolerance exists, 2700K or 3000K variants are acceptable alternatives with identical luminous output.
Q: What is the MSL (Moisture Sensitivity Level) rating and why does it matter?
A: All parts are rated MSL 4 (72 Hours), indicating the component can be exposed to ambient conditions (23°C, 50% relative humidity) for up to 72 hours after packaging before soldering. This standard rating applies to both the original and substitute parts, requiring identical moisture control procedures during storage and assembly.
Q: Are there any electrical parameter differences that affect circuit design?
A: The primary difference is forward voltage: 4.6V (original) vs. 3.3V (substitutes). At the standard 350mA test current, luminous flux is identical (59lm). Maximum current rating increases from 500mA to 700mA in substitutes, providing design headroom for future applications. Existing current-limiting circuits require no modification.
