Engineering Selection Recommendations

All listed substitute parts are active product status components from CreeLED's XLamp® XR-E series, providing continuity for designs currently using the obsolete XRCWHT-L1-0000-00A05. The XLamp® XR-E variants maintain identical mechanical footprint, package configuration, and luminous flux output while offering improved thermal performance (8°C/W versus 12°C/W) and lower forward voltage (3.3V versus 4.6V).

Selection among the XLamp® XR-E variants (XREWHT-L1-0000-00A05, XREWHT-L1-0000-00A07, XREWHT-L1-0000-00A08, XREWHT-L1-0000-00A09, XREWHT-L1-0000-00A10, XREWHT-L1-0000-00A37, XREWHT-L1-0000-00AB1, XREWHT-L1-0000-00AB2, XREWHT-L1-0000-00AB3) is determined by application-specific color temperature and CRI requirements not specified in the main part datasheet. XREWHT-L1-0000-00A01 is qualified as a direct parametric equivalent with extended color temperature range (5000K–10000K) and CRI specification (75 Typ).

All substitute parts maintain RoHS Compliant and REACH Unaffected certifications, ensuring regulatory compliance equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00A05 be used as a direct replacement for XRCWHT-L1-0000-00A05?

A: Yes. Both components share identical luminous flux (91 lm at 350 mA), viewing angle (90°), package configuration (3529 / 9073 Metric), and physical dimensions. The forward voltage difference (3.3V versus 4.6V) and improved thermal resistance (8°C/W versus 12°C/W) of the XLamp® XR-E variant are compatible with existing circuit designs and provide performance benefits.

Q: What is the difference between the various XREWHT-L1-0000-00A variants?

A: All listed XLamp® XR-E variants maintain identical electrical performance (91 lm flux, 350 mA test current, 79 lm/W efficiency) and mechanical specifications. Differentiation among part numbers (A05, A07, A08, A09, A10, A37, AB1, AB2, AB3) reflects binning for color temperature and CRI characteristics not detailed in the provided specifications. Selection should be based on application color temperature requirements.

Q: Are there any thermal management considerations when substituting to XLamp® XR-E?

A: The XLamp® XR-E series exhibits superior thermal performance (8°C/W thermal resistance) compared to the original XLamp® XR-C (12°C/W). This improvement reduces junction temperature at equivalent operating currents, enhancing reliability and extending component lifespan. No thermal management modifications are required; existing designs will benefit from this improvement.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are RoHS Compliant and REACH Unaffected, matching the compliance profile of XRCWHT-L1-0000-00A05. Moisture Sensitivity Level (MSL 4, 72 Hours) is consistent across all components.

Q: Can XREWHT-L1-0000-00A01 be used if color temperature range is required?

A: Yes. XREWHT-L1-0000-00A01 is the only substitute part with specified color temperature range (5000K–10000K Cool White) and CRI rating (75 Typ). It maintains all electrical and mechanical compatibility parameters and is suitable for applications requiring extended color temperature specification.
