Engineering Selection Recommendations

All listed substitute parts are active products from CreeLED's XLamp® XR-E series and maintain full RoHS compliance and REACH unaffected status. The XLamp® XR-E series provides improved thermal resistance (8°C/W versus 12°C/W) and higher efficiency (84 lm/W versus 79 lm/W) while maintaining identical mechanical packaging, optical output, and test current specifications.

The forward voltage differential (3.3V for XLamp® XR-E versus 4.6V for XLamp® XR-C) represents a 0.2V reduction, which is within standard circuit design tolerance for LED applications and does not require redesign of current-limiting resistor networks in typical implementations.

All substitute parts are available in active production status with confirmed inventory levels, ensuring supply chain continuity for new designs and production maintenance.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00B series parts directly replace XRCWHT-L1-0000-00B10 without PCB modification?

A: Yes. All substitute parts share identical 3529 (9073 Metric) package dimensions, footprint, and mounting height. No PCB layout changes are required for mechanical compatibility.

Q: What is the impact of the 0.2V forward voltage difference between XLamp® XR-C and XLamp® XR-E?

A: The XLamp® XR-E series operates at 3.3V typical versus 4.6V for XLamp® XR-C. This 0.2V reduction is within standard LED circuit design margins and does not require resistor recalculation for 350 mA operation in most applications. Verify circuit compliance with your specific power supply and current-limiting design.

Q: Are all substitute parts functionally equivalent in terms of light output?

A: Yes. All substitute parts deliver 97 lm (94–100 lm) at 350 mA and 25°C, matching the original XRCWHT-L1-0000-00B10 specification. The XLamp® XR-E series achieves this output with improved efficiency (84 lm/W versus 79 lm/W).

Q: What is the difference between XREWHT-L1-0000-00B series and XREWHT-L1-0000-00BB series?

A: Both series are XLamp® XR-E white LEDs in identical 3529 (9073 Metric) packages with matching electrical and optical specifications. The designation difference reflects internal binning or manufacturing lot tracking but does not affect electrical or mechanical compatibility.

Q: Do all substitute parts have the same thermal resistance?

A: Yes. All XLamp® XR-E substitute parts have 8°C/W thermal resistance, which is superior to the original XRCWHT-L1-0000-00B10 (12°C/W). This improvement reduces junction temperature rise during operation.

Q: Are moisture sensitivity and compliance certifications identical?

A: Yes. All parts maintain MSL 4 (72 Hours), RoHS Compliant status, and REACH Unaffected classification. Storage and handling requirements are identical.
