Engineering Selection Recommendations

All listed XLamp® XR-E substitutes are active production parts with RoHS compliance and identical MSL ratings. The transition from XLamp® XR-C to XLamp® XR-E represents a product line evolution within CreeLED's portfolio. Substitute selection should be based on application-specific requirements:

XREWHT-L1-0000-00801 is designated for cool white applications (5000K ~ 10000K CCT range) and includes CRI specification of 75 (Typ), suitable for applications requiring defined color temperature performance.

XREWHT-L1-0000-008B1 through XREWHT-L1-0000-008B9 are neutral to warm white variants within the XLamp® XR-E series, offering flexibility for different color temperature requirements while maintaining identical electrical and mechanical compatibility.

All substitutes operate at 3.3V forward voltage compared to the original 4.6V specification, resulting in reduced power consumption at equivalent current levels. The improved thermal resistance (8°C/W versus 12°C/W) provides enhanced thermal performance in high-density applications.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008B series parts directly replace XRCWHT-L1-0000-00808 in existing PCB designs?

A: Yes. All substitute parts maintain identical 3529 (9073 Metric) package dimensions, identical 0.354" L x 0.276" W footprint, and identical 0.181" (4.60mm) seated height. Surface mount placement and reflow parameters remain compatible.

Q: What is the impact of the 3.3V versus 4.6V forward voltage difference?

A: The 0.2V reduction in forward voltage decreases power dissipation at equivalent 350mA test current. Circuit designs must accommodate this lower voltage requirement. Current-limiting resistor or driver circuit adjustments may be necessary depending on the power supply configuration.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original XRCWHT-L1-0000-00808 packaging format is not specified in the provided data. Confirm packaging requirements with procurement specifications.

Q: What is the significance of the improved thermal resistance in XLamp® XR-E substitutes?

A: The reduction from 12°C/W to 8°C/W thermal resistance indicates improved heat dissipation capability. This allows higher sustained current operation or reduced junction temperature at equivalent power levels, extending component lifetime in thermally constrained applications.

Q: How do the neutral and warm white variants differ functionally?

A: XREWHT-L1-0000-008B1 through XREWHT-L1-0000-008B9 variants maintain identical electrical specifications and luminous flux output. Differences are limited to color temperature binning, which is not specified in the provided data. Selection should be based on application color temperature requirements.

Q: Is the 77lm flux specification guaranteed across all substitute parts?

A: All substitute parts specify 77lm flux at 25°C with 350mA test current, with tolerance range of 74lm to 81lm. This matches the original XRCWHT-L1-0000-00808 specification exactly.
