Engineering Selection Recommendations
All listed substitute parts are from the active production XLamp® XR-E series and are qualified replacements for the obsolete XRCWHT-L1-0000-00A10. Selection among the substitute options is based on the following engineering criteria:
Primary Selection Criteria:
- All substitutes maintain identical optical output (91 lm at 350 mA test current) and mechanical compatibility (3529 package, 90° viewing angle, identical footprint)
- All substitutes are RoHS Compliant and REACH Unaffected, meeting regulatory requirements equivalent to the main part
- All substitutes carry Active product status, ensuring long-term supply chain availability
Electrical Compatibility:
- Forward voltage reduction from 4.6V to 3.3V in XLamp® XR-E substitutes results in improved power efficiency (79 lm/W vs. 74 lm/W)
- The 0.2V forward voltage difference is within acceptable design margins for standard LED driver circuits
- Enhanced maximum current rating (1A in XREWHT-L1-0000-00A01 vs. 500 mA in main part) provides additional operational headroom
Thermal Performance:
- Improved thermal resistance (8°C/W vs. 12°C/W) in all XLamp® XR-E substitutes enables better heat dissipation and extended component lifespan
Packaging and Compliance:
- Identical MSL rating (4, 72 Hours) ensures equivalent moisture handling and storage requirements
- All substitutes are supplied in Tape & Reel (TR) packaging for automated assembly compatibility
Frequently Asked Questions (FAQ)
Q: Can 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, and XREWHT-L1-0000-00AB3 be used as direct drop-in replacements for XRCWHT-L1-0000-00A10?
A: Yes. All listed XLamp® XR-E substitutes are direct drop-in replacements. They share identical package dimensions (3529, 9.00 mm × 7.00 mm), mounting type (Surface Mount), height (4.60 mm max), and optical output (91 lm at 350 mA). PCB footprints and reflow profiles are compatible without modification.
Q: What is the difference between XREWHT-L1-0000-00A01 and the other XLamp® XR-E substitutes?
A: XREWHT-L1-0000-00A01 is specified with a defined CCT range (5000K–10000K Cool White) and a CRI value of 75 (Typ). The remaining substitutes (XREWHT-L1-0000-00A05, A07, A08, A09, A10, A37, AB1, AB2, AB3) do not have CCT or CRI specifications provided. All maintain identical flux output and electrical parameters at the 350 mA test current.
Q: Will the 0.2V forward voltage difference (4.6V to 3.3V) affect circuit operation?
A: No. The forward voltage reduction from 4.6V to 3.3V is within standard design tolerances for LED driver circuits. This difference results in improved power efficiency (79 lm/W vs. 74 lm/W) and is compatible with existing current-limiting driver designs. No circuit modifications are required.
Q: Are all substitute parts available in the same packaging format?
A: Yes. All XLamp® XR-E substitutes are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The main part XRCWHT-L1-0000-00A10 was supplied in standard packaging; substitutes maintain equivalent handling and storage requirements (MSL 4, 72 Hours).
Q: What is the thermal advantage of switching to XLamp® XR-E substitutes?
A: XLamp® XR-E substitutes feature improved thermal resistance of 8°C/W compared to 12°C/W in the obsolete XLamp® XR-C main part. This 33% improvement in thermal performance enables better heat dissipation, lower junction temperatures, and extended operational lifespan under identical current conditions.
Q: Are there any compliance or regulatory differences between the main part and substitutes?
A: No. All substitute parts maintain identical compliance status: RoHS Compliant and REACH Unaffected. Regulatory requirements and certifications are equivalent across the main part and all listed substitutes.
Q: Which substitute should I select if color temperature consistency is critical?
A: XREWHT-L1-0000-00A01 is the only substitute with a defined CCT specification (5000K–10000K Cool White) and CRI value (75 Typ). If color temperature consistency is required, this part is the recommended selection. Other substitutes do not have CCT specifications and may exhibit color temperature variation within the white LED spectrum.
