Engineering Selection Recommendations

All listed substitute parts are active products from CreeLED's XLamp® XR-E series and carry identical RoHS Compliance and MSL ratings as the original XRCWHT-L1-0000-00710. The XR-E series provides improved thermal performance (8°C/W versus 12°C/W) and higher luminous efficacy (61 lm/W to 67 lm/W versus 58 lm/W).

XREWHT-L1-0000-00801 offers the highest luminous output at 77lm with specified CRI of 75 and extended maximum current rating of 1A, suitable for applications requiring enhanced brightness and color rendering.

XREWHT-L1-0000-007B1, XREWHT-L1-0000-007B3, XREWHT-L1-0000-007B5 maintain the original 71lm output specification with 3.3V forward voltage, providing direct functional equivalence with improved thermal characteristics. These variants differ in color temperature binning (neutral to warm white) but share identical electrical and mechanical parameters.

Forward voltage reduction from 4.6V to 3.3V in XR-E substitutes requires circuit verification to ensure adequate current limiting and voltage headroom in existing designs. Thermal resistance improvement permits higher sustained current operation within the same package envelope.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00801 directly replace XRCWHT-L1-0000-00710 in existing PCB layouts?

A: Yes. Both components use identical 3529 (9073 Metric) package with matching footprint dimensions (9.00mm x 7.00mm) and seated height (4.60mm). PCB layout compatibility is confirmed. Circuit design must accommodate the 0.2V forward voltage reduction (4.6V to 3.3V) and verify current limiting resistor values remain appropriate.

Q: What is the difference between XREWHT-L1-0000-007B1, 007B3, and 007B5?

A: These parts are parametric equivalents within the XLamp® XR-E series, differentiated by color temperature binning (neutral white versus warm white). All three share identical electrical specifications: 3.3V forward voltage, 350mA test current, 71lm output, and 61 lm/W efficiency. Selection depends on application color temperature requirements. Mechanical and thermal properties are identical.

Q: Does the improved thermal resistance (8°C/W versus 12°C/W) affect circuit design?

A: Improved thermal resistance permits higher sustained current operation and lower junction temperature rise under identical power dissipation. Existing designs require no modification; however, thermal performance is enhanced. Applications with thermal constraints benefit from the XR-E series' superior heat dissipation characteristics.

Q: Are all substitute parts RoHS Compliant and MSL rated identically?

A: Yes. All listed substitute parts carry RoHS Compliant status and MSL rating 4 (72 Hours), matching the original XRCWHT-L1-0000-00710. Regulatory and moisture sensitivity requirements are equivalent across all alternatives.

Q: Why is XRCWHT-L1-0000-00710 classified as obsolete?

A: The XLamp® XR-C series has been superseded by the XLamp® XR-E series in CreeLED's product portfolio. The XR-E generation offers improved efficiency, thermal performance, and extended maximum current ratings while maintaining mechanical compatibility. Active inventory of XR-E alternatives ensures supply chain continuity.

Q: What is the luminous output difference between the main part and XREWHT-L1-0000-00801?

A: XREWHT-L1-0000-00801 delivers 77lm (74lm ~ 81lm) at 350mA test current, compared to 71lm (67lm ~ 74lm) for XRCWHT-L1-0000-00710. This represents approximately 8.5% higher luminous output within the same package and current rating. The increase is accompanied by improved efficiency (67 lm/W versus 58 lm/W).
