Substitute Part Grouping Explanation
Substitute parts for XRCWHT-L1-0000-00B08 are qualified based on the following criteria:
Electrical Compatibility:
- Identical flux output at 25°C and 350 mA test current (97 lm, 94–100 lm range)
- Identical test current (350 mA)
- Identical viewing angle (90°)
- Forward voltage tolerance: XR-E series operates at 3.3V (0.2V lower than XR-C), which is within acceptable substitution range for constant-current driver circuits
Mechanical Compatibility:
- Identical package format: 3529 (9073 Metric)

Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-00B08 directly replace XRCWHT-L1-0000-00B08 without circuit modification?
A: Yes. Both parts operate at 350 mA test current with identical 97 lm flux output and 90° viewing angle. The 0.2V forward voltage difference (4.6V vs. 3.3V) is negligible in constant-current driver circuits and does not require design changes.
Q: What is the difference between cool white and neutral white variants?
A: XREWHT-L1-0000-00B01 is specified as cool white with CCT range 5000K–10000K and CRI 75 (Typ). XREWHT-L1-0000-00BB1, XREWHT-L1-0000-00BB2, and XREWHT-L1-0000-00BB3 are neutral white variants. All maintain identical electrical output and mechanical compatibility. Selection depends on application color temperature requirements.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All XLamp® XR-E substitutes are supplied in Tape & Reel (TR) format, consistent with surface mount production requirements.
Q: Does the improved thermal resistance of XR-E parts affect circuit design?
A: No. The lower thermal resistance (8°C/W vs. 12°C/W) is a performance improvement that reduces junction temperature at identical operating current. Existing circuit designs require no modification.
Q: Are all substitute parts RoHS and REACH compliant?
A: Yes. All listed XLamp® XR-E variants are RoHS Compliant and REACH Unaffected, maintaining regulatory compliance with the original XRCWHT-L1-0000-00B08.
Q: What is the MSL rating for these components?
A: All parts carry MSL 4 (72 Hours) moisture sensitivity level, requiring standard ESD and moisture control handling during storage and assembly.
