Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004E8 is an active product substitute for the obsolete XRCWHT-L1-0000-003B5. Both components share identical mechanical compatibility through matching 3529 package dimensions and surface mount configuration. Electrical operation at 350mA test current is equivalent, with the substitute offering higher maximum current rating (700mA vs. 500mA) and improved thermal performance (8°C/W vs. 12°C/W).

Both parts maintain RoHS Compliance and REACH Unaffected status, ensuring regulatory alignment. The substitute provides higher luminous flux (54lm vs. 49lm) and improved efficiency (47 lm/W vs. 40 lm/W) at identical test conditions. The forward voltage difference (3.3V vs. 4.6V) is within typical circuit design tolerance for LED driver circuits.

Selection of the XREWHT-L1-0000-004E8 is supported by active product status, superior thermal characteristics, and enhanced optical performance while maintaining full mechanical and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004E8 be used as a direct replacement for XRCWHT-L1-0000-003B5 in existing PCB designs?

A: Yes. Both components use identical 3529 (9073 Metric) package dimensions and surface mount configuration. PCB footprints and reflow profiles remain compatible. The 0.2V forward voltage difference (3.3V vs. 4.6V) is within standard LED driver circuit tolerance.

Q: What are the key differences between these two parts?

A: The substitute (XREWHT-L1-0000-004E8) belongs to the newer XLamp® XR-E series with active product status. It provides higher luminous flux (54lm vs. 49lm), improved efficiency (47 lm/W vs. 40 lm/W), better thermal performance (8°C/W vs. 12°C/W), and higher maximum current rating (700mA vs. 500mA). The substitute includes specified color temperature (2700K warm white) and CRI rating (80 Typ).

Q: Are both parts available in the same packaging format?

A: Yes. Both XRCWHT-L1-0000-003B5 and XREWHT-L1-0000-004E8 are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level 4 (72 Hours) handling requirements.

Q: Does the substitute meet the same regulatory requirements?

A: Yes. Both parts are RoHS Compliant and REACH Unaffected, maintaining identical regulatory status for applications requiring these certifications.

Q: What is the impact of the improved thermal resistance on circuit design?

A: The substitute's lower thermal resistance (8°C/W vs. 12°C/W) results in reduced junction temperature at equivalent power dissipation. This allows for higher sustained current operation or improved reliability in thermally constrained applications.
