Engineering Selection Recommendations
All listed XLamp® XR-E substitute parts maintain active product status with CreeLED, Inc., ensuring long-term supply availability and continued manufacturer support. The transition from XLamp® XR-C to XLamp® XR-E series represents a forward-compatible upgrade path for obsolete component replacement.
Primary Selection Criteria:
XREWHT-L1-0000-00801 is the direct functional equivalent, offering improved thermal performance (8°C/W versus 12°C/W) and extended maximum current rating (1A versus 500mA) while maintaining identical optical output at 350mA test current. This part is specified for cool white color temperature range (5000K ~ 10000K) with CRI 75 typical.
XREWHT-L1-0000-008B1 through XREWHT-L1-0000-008B9 provide parametric equivalence with identical electrical and optical characteristics at 350mA operation. These parts differ in color temperature binning (neutral white and warm white variants) but maintain mechanical compatibility and thermal performance improvements over the original XRCWHT-L1-0000-00809.
All substitute parts comply with RoHS and REACH regulations, maintaining MSL 4 (72 Hours) moisture sensitivity classification. Forward voltage reduction from 4.6V to 3.3V typical improves power efficiency by approximately 6% at constant current operation.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-00801 directly replace XRCWHT-L1-0000-00809 in existing designs?
A: Yes. Both parts share identical package (3529/9073 Metric), mechanical dimensions (9.00mm x 7.00mm x 4.60mm), viewing angle (90°), and optical output (77lm at 350mA). Forward voltage differs by 0.2V (3.3V versus 4.6V), requiring circuit verification for current-limiting designs. Thermal resistance improvement (8°C/W versus 12°C/W) provides enhanced thermal performance.
Q: What is the difference between XREWHT-L1-0000-00801 and the XREWHT-L1-0000-008B series?
A: XREWHT-L1-0000-00801 specifies cool white color temperature (5000K ~ 10000K) with CRI 75 typical. The 008B series comprises neutral white (008B1 through 008B4) and warm white (008B5 through 008B9) variants. All maintain identical electrical and optical performance at 350mA test current. Selection depends on application color temperature requirements.
Q: Are all substitute parts in Tape & Reel packaging?
A: Yes. All listed XLamp® XR-E substitutes are supplied in Tape & Reel (TR) packaging format, consistent with surface mount assembly requirements. Original XRCWHT-L1-0000-00809 packaging format is not specified in available data.
Q: What is the impact of forward voltage reduction from 4.6V to 3.3V?
A: The 0.2V reduction decreases power dissipation at constant 350mA operation. For current-limiting resistor designs, recalculation is required. For constant current driver circuits, no modification is necessary. Lumens/Watt efficiency improves from 63 lm/W to 67 lm/W.
Q: Do all substitute parts maintain the same moisture sensitivity level?
A: Yes. All substitute parts maintain MSL 4 (72 Hours) classification, identical to the original XRCWHT-L1-0000-00809. Storage and handling procedures remain unchanged.
Q: Which substitute part offers the best thermal performance?
A: All XLamp® XR-E substitutes provide identical thermal resistance of 8°C/W, representing a 33% improvement over the original part's 12°C/W rating. This improvement applies uniformly across XREWHT-L1-0000-00801 and all 008B variants.
