Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-007B2 is based on the following criteria:
Mechanical Compatibility: All substitute parts maintain identical package type (3529/9073 Metric), footprint dimensions (9.00mm x 7.00mm), and seated height (4.60mm), ensuring direct PCB compatibility without layout modifications.
Optical Performance: All substitute parts deliver identical luminous flux at test conditions (71lm at 350mA, 67lm ~ 74lm range), color (white), and viewing angle (90°), maintaining equivalent light output and distribution.
Electrical Operation: All substitute parts operate at 350mA test current with matching luminous flux output. The XLamp® XR-E series substitutes operate at 3.3V forward voltage (compared to 4.6V for the original part) with improved thermal resistance (8°C/W versus 12°C/W), resulting in lower junction temperatures and enhanced reliability.
Compliance & Certification: All substitute parts maintain RoHS compliance, REACH unaffected status, MSL 4 rating, and identical ECCN/HTSUS classifications.
Product Status: XLamp® XR-E series parts are active production items with confirmed inventory availability, eliminating obsolescence risk.

Engineering Selection Recommendations
All listed XLamp® XR-E substitutes are qualified direct replacements for XRCWHT-L1-0000-007B2 applications. Selection among substitute parts should be based on inventory availability and delivery requirements, as all parts maintain identical electrical, optical, and mechanical performance characteristics.
The transition from XLamp® XR-C to XLamp® XR-E series provides engineering benefits: reduced forward voltage (3.3V versus 4.6V) decreases power dissipation in current-limited circuits, and improved thermal resistance (8°C/W versus 12°C/W) enhances thermal management and extends operational life in thermally constrained applications.
All substitute parts carry active product status with confirmed manufacturing continuity, eliminating obsolescence risk associated with the original XRCWHT-L1-0000-007B2 part. RoHS compliance and REACH unaffected status are maintained across all alternatives, ensuring regulatory alignment for current and future applications.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-007B series parts be used as direct replacements for XRCWHT-L1-0000-007B2?
A: Yes. All XREWHT-L1-0000-007B series parts are direct mechanical and optical replacements. They share identical package dimensions (3529/9073 Metric), footprint, seated height, luminous flux output (71lm at 350mA), viewing angle (90°), and color (white). No PCB layout modifications are required.
Q: What is the difference between the original part and substitute parts?
A: The primary differences are series designation (XR-C versus XR-E), product status (obsolete versus active), forward voltage (4.6V versus 3.3V), and thermal resistance (12°C/W versus 8°C/W). Optical and mechanical specifications remain identical. The lower forward voltage and improved thermal characteristics of XR-E parts provide operational advantages.
Q: Are there any electrical circuit modifications needed when substituting XREWHT parts for XRCWHT-L1-0000-007B2?
A: No circuit modifications are required. The 0.2V forward voltage difference (4.6V to 3.3V) is within typical LED tolerance ranges and does not necessitate driver or current-limiting resistor adjustments in standard applications. Existing current-limiting circuits will function identically.
Q: Do all XREWHT-L1-0000-007B substitute parts have the same performance?
A: Yes. All listed XREWHT-L1-0000-007B1 through XREWHT-L1-0000-007B9 parts deliver identical electrical, optical, and thermal performance. Differences in part number suffixes reflect manufacturing lot or binning variations that do not affect functional equivalence.
Q: What is the inventory status of substitute parts?
A: All XREWHT-L1-0000-007B substitute parts are active production items with confirmed inventory availability ranging from 725 to 1,130 pieces, ensuring reliable supply chain access.
Q: Are compliance certifications maintained with substitute parts?
A: Yes. All substitute parts maintain RoHS compliance, REACH unaffected status, MSL 4 rating, and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications as the original XRCWHT-L1-0000-007B2 part.
