Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00901 be used as a direct replacement for XRCWHT-L1-0000-00905?

A: Yes. XREWHT-L1-0000-00901 is a direct substitute. Both parts share identical package dimensions (3529 / 9073 Metric), mounting type (Surface Mount), optical output (84 lm at 350mA), viewing angle (90°), and regulatory compliance (RoHS Compliant, REACH Unaffected). The forward voltage difference (3.3V vs. 4.6V) is within acceptable design margins for current-regulated LED driver circuits.

Q: What is the difference between XREWHT-L1-0000-00901 and the other XR-E substitutes listed?

A: XREWHT-L1-0000-00901 is designated as "Cool White" with a specified CCT range of 5000K–10000K and includes a CRI specification of 75 (Typ). The remaining XR-E substitutes (XREWHT-L1-0000-00905, -00907, -00908, -00909, -00910, -00937, -009B1, -009B2, -009B3) do not specify CCT or CRI values in the provided data. All parts deliver identical flux output (84 lm) and electrical characteristics at 350mA test current. Selection between these parts depends on specific color temperature and color rendering requirements for the application.

Q: Are there any thermal management considerations when substituting to XR-E series?

A: The XR-E series exhibits improved thermal performance with thermal resistance of 8°C/W compared to the original XR-C 12°C/W. This represents a 33% reduction in thermal resistance, resulting in lower junction temperatures under identical operating conditions. Existing thermal design margins in the original circuit will be maintained or improved with XR-E substitutes.

Q: What is the impact of the 0.2V forward voltage difference on circuit design?

A: The reduction from 4.6V to 3.3V typical forward voltage in XR-E parts reduces power dissipation by approximately 5.7% at 350mA test current. For current-regulated LED driver circuits, this voltage difference is absorbed within the driver's compliance voltage range and does not require circuit modification. Voltage-regulated designs should verify that the reduced forward voltage does not cause the driver to exit regulation; however, the 0.2V difference is typically within standard design margins.

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

A: All substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly. The original XRCWHT-L1-0000-00905 was supplied in standard packaging; however, the TR format of substitutes is compatible with standard SMD assembly equipment and processes.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All parts, including the original and all substitutes, are rated MSL 4 (72 Hours). This classification requires that components be stored in dry conditions and used within 72 hours of exposure to ambient humidity after opening the moisture barrier bag. Standard ESD and moisture control procedures used in professional electronics manufacturing environments are sufficient to maintain compliance with this specification.
