Engineering Selection Recommendations
All listed XLamp® XR-E substitutes are active products with RoHS compliance and REACH unaffected status, ensuring regulatory alignment for current production. The XLamp® XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficacy (79 lm/W vs. 74 lm/W) compared to the obsolete XLamp® XR-C series.
Forward voltage reduction from 4.6V to 3.3V requires circuit adjustment. Current-limiting resistor values or LED driver settings must be recalculated to maintain 350 mA nominal operation. Identical flux output (91 lm at 350 mA), viewing angle (90°), package dimensions (3529 / 9073 Metric), and thermal characteristics enable direct mechanical and optical substitution.
XREWHT-L1-0000-00A01 includes specified color temperature range (5000K–10000K cool white) and CRI rating (75 Typ), providing additional optical specification data. Remaining XLamp® XR-E variants (XREWHT-L1-0000-00A05, A07, A08, A09, A10, A37, AB1, AB2, AB3) maintain identical electrical and mechanical parameters without specified CCT or CRI values, indicating standard white binning.
Frequently Asked Questions (FAQ)
Q: Why is the XRCWHT-L1-0000-00A09 obsolete? A: The XLamp® XR-C series has reached end-of-life status. CreeLED has transitioned production to the XLamp® XR-E series, which provides superior thermal performance and efficiency while maintaining electrical and mechanical compatibility.
Q: Can XLamp® XR-E parts directly replace XLamp® XR-C in existing designs? A: Mechanical and optical substitution is direct due to identical package dimensions (3529 / 9073 Metric), height (4.60 mm max), viewing angle (90°), and flux output (91 lm at 350 mA). Forward voltage adjustment from 4.6V to 3.3V is required in the LED driver circuit or current-limiting resistor network.
Q: What is the difference between XREWHT-L1-0000-00A01 and other XLamp® XR-E variants? A: XREWHT-L1-0000-00A01 specifies color temperature range (5000K–10000K) and CRI (75 Typ), indicating cool white binning with defined color rendering. Other variants (A05, A07, A08, A09, A10, A37, AB1, AB2, AB3) maintain identical electrical performance without specified CCT or CRI values.
Q: Are all substitute parts RoHS compliant? A: Yes. All listed XLamp® XR-E substitutes are RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
Q: What is the thermal advantage of XLamp® XR-E over XLamp® XR-C? A: Thermal resistance improves from 12°C/W to 8°C/W, reducing junction temperature rise by approximately 33% at equivalent power dissipation. This enables higher current operation or improved reliability in thermally constrained applications.
Q: Do substitute parts require PCB layout changes? A: No. Identical package dimensions (0.354" L × 0.276" W / 9.00 mm × 7.00 mm) and height (0.181" / 4.60 mm) permit direct PCB footprint reuse without layout modification.
Q: What is MSL 4 (72 Hours) and why does it matter? A: Moisture Sensitivity Level 4 indicates the component absorbs moisture during storage. Reflow soldering must occur within 72 hours of package opening, or the component must be baked at 125°C for 24 hours to remove absorbed moisture and prevent delamination.
