Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-00B07 (XLamp® XR-E) be used as a direct replacement for XRCWHT-L1-0000-00B07 (XLamp® XR-C)?
A: Yes. Both parts share identical package footprint (3529 / 9073 Metric), mounting type (Surface Mount), physical dimensions (0.354" L × 0.276" W, 4.60 mm height), viewing angle (90°), and luminous flux output (97 lm at 350 mA). The XR-E variant operates at 3.3V forward voltage compared to 4.6V in the XR-C, resulting in lower power dissipation. No PCB layout changes are required.
Q: What is the difference between the various XREWHT-L1-0000-00B0X part numbers?
A: All listed XLamp® XR-E variants (B01, B05, B07, B08, B09, B10, B37, BB1, BB2, BB3) are electrically and mechanically identical. They differ only in internal binning or manufacturing lot designation, which does not affect electrical performance or compatibility. Selection can be based on inventory availability.
Q: Why is the thermal resistance lower in the XLamp® XR-E series?
A: The XLamp® XR-E series incorporates improved thermal design, reducing junction-to-case thermal resistance from 12°C/W to 8°C/W. This enhancement allows better heat dissipation and supports higher ambient temperature operation without exceeding maximum junction temperature limits.
Q: Are all substitute parts RoHS Compliant and REACH Unaffected?
A: Yes. All listed substitute parts maintain RoHS Compliance and REACH Unaffected status, identical to the original XRCWHT-L1-0000-00B07.
Q: What is the Moisture Sensitivity Level (MSL) for these parts?
A: All parts, including the original and all substitutes, are rated MSL 4 (72 Hours), indicating identical moisture handling and storage requirements.
Q: Can I mix XLamp® XR-C and XLamp® XR-E parts in the same assembly?
A: Yes. Both series share identical package footprint, mounting type, and electrical performance at the specified test current (350 mA). However, for consistency and long-term supply chain stability, using a single series across production is recommended.
