Engineering Selection Recommendations
All listed substitute parts are from the active XLamp® XR-E product line and maintain full RoHS compliance and REACH unaffected status. The primary distinction between the main part (XRCWHT-L1-0000-008B2) and substitute parts is product status: the main part is obsolete, while all substitutes are active.
Substitute parts deliver improved thermal performance with thermal resistance of 8°C/W compared to 12°C/W for the main part. Forward voltage is reduced from 4.6 V to 3.3 V, resulting in lower power dissipation and improved luminous efficiency at 67 lm/W versus 63 lm/W.
All substitute parts maintain identical mechanical compatibility, identical flux output specification at the 350 mA test current, identical 90° viewing angle, and identical 3529 (9073 Metric) package form factor. All parts are surface mount components with identical physical dimensions and seated height.
Selection among substitute parts should be based on specific color temperature or binning requirements as indicated by the part number suffix, as all electrical and mechanical parameters remain constant across the substitute part group.
Frequently Asked Questions (FAQ)
Q: Why is the XRCWHT-L1-0000-008B2 being discontinued? A: The XRCWHT-L1-0000-008B2 is classified as obsolete product status. The XLamp® XR-E series provides equivalent or superior performance in the same package form factor.
Q: Are substitute parts mechanically compatible with the original design? A: Yes. All substitute parts use the identical 3529 (9073 Metric) package, identical physical dimensions (9.00 mm × 7.00 mm), and identical seated height (4.60 mm). No PCB layout modifications are required.
Q: What is the difference in electrical performance? A: Substitute parts operate at 3.3 V forward voltage compared to 4.6 V for the main part. Both deliver 77 lm flux output at 350 mA test current. Substitute parts achieve 67 lm/W efficiency versus 63 lm/W for the main part, representing a 6% efficiency improvement.
Q: Do substitute parts have better thermal characteristics? A: Yes. Substitute parts have thermal resistance of 8°C/W compared to 12°C/W for the main part, representing a 33% improvement in thermal performance.
Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All substitute parts are RoHS Compliant and REACH Unaffected, matching the compliance status of the main part.
Q: What is the difference between the various substitute part numbers? A: All substitute parts listed (XREWHT-L1-0000-008E5, XREWHT-L1-0000-008B1 through XREWHT-L1-0000-008B9) maintain identical electrical and mechanical specifications. Differences in part number suffixes indicate color temperature or binning variations. XREWHT-L1-0000-008E5 is specified as 4000K Neutral White with 75 CRI typical; remaining parts are specified as White without CCT designation.
Q: What is the Moisture Sensitivity Level (MSL) for substitute parts? A: All substitute parts have MSL 4 (72 Hours), identical to the main part. Standard moisture control procedures for MSL 4 components apply.
Q: Can substitute parts be used in existing production without design changes? A: Yes. Substitute parts are pin-compatible, package-compatible, and functionally equivalent. The 0.2 V reduction in forward voltage may result in slightly reduced power dissipation in series-resistor-limited circuits, which is beneficial. No design changes are required.
