Engineering Selection Recommendations

The XREWHT-L1-0000-004E6 is a qualified substitute for the obsolete XRCWHT-L1-0000-002A6 based on the following engineering factors:

Product Status & Availability: The substitute part carries Active product status, ensuring continued availability and supply chain reliability. The main part's Obsolete classification creates long-term sourcing risk.

Compliance & Certification: Both parts maintain RoHS Compliant status and identical MSL Rating 4 specifications, ensuring equivalent handling and storage requirements.

Mechanical Compatibility: Identical package footprint (3529 / 9073 Metric), physical dimensions (9.00mm × 7.00mm), and maximum seated height (4.60mm) guarantee direct PCB layout compatibility without redesign.

Electrical Compatibility: The substitute operates at 3.3V typical forward voltage compared to 4.6V for the main part. Both function within standard LED driver voltage ranges. The substitute's 700mA maximum current rating exceeds the main part's 500mA rating, providing design margin.

Performance Characteristics: The substitute delivers 54 lm at 350mA test current versus 43 lm for the main part, representing a 25.6% luminous flux improvement. Efficiency increases from 35 lm/W to 47 lm/W. The substitute includes CRI specification of 80 (Typ), whereas the main part does not specify CRI. Thermal resistance improves from 12°C/W to 8°C/W, enhancing heat dissipation performance.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-004E6 be used as a direct replacement for XRCWHT-L1-0000-002A6 without circuit modification?

A: Yes. Both parts share identical package geometry (3529 / 9073 Metric), footprint dimensions (9.00mm × 7.00mm), and viewing angle (90°). The forward voltage difference (3.3V vs. 4.6V) is within typical LED driver tolerance ranges and does not require circuit redesign for standard applications.

Q: What is the impact of the 0.2V forward voltage difference between these parts?

A: The XREWHT-L1-0000-004E6 operates at 3.3V typical versus 4.6V for the XRCWHT-L1-0000-002A6. This 0.2V reduction typically results in slightly lower power consumption at the same 350mA test current. Most LED driver circuits accommodate this variation within their design specifications. Verify your specific driver's voltage regulation range if operating near minimum supply voltage limits.

Q: Why does the substitute part have higher luminous flux at the same test current?

A: The XREWHT-L1-0000-004E6 represents a newer generation within CreeLED's XLamp® product line (XR-E vs. XR-C). Generational improvements in LED die design and phosphor technology result in higher photon conversion efficiency, delivering 54 lm versus 43 lm at 350mA.

Q: Are the thermal characteristics compatible?

A: The substitute part exhibits superior thermal performance with 8°C/W thermal resistance compared to 12°C/W for the main part. This improvement reduces junction temperature rise under identical operating conditions, enhancing reliability and lifespan. No thermal design modifications are required; the substitute performs better in existing thermal environments.

Q: What is the significance of the CRI specification on the substitute part?

A: The XREWHT-L1-0000-004E6 specifies CRI (Color Rendering Index) of 80 (Typ), whereas the main part does not provide CRI data. CRI 80 indicates good color rendering capability for warm white 3500K applications. If your application requires specific CRI performance, the substitute's documented specification provides engineering assurance.

Q: Are both parts RoHS Compliant and suitable for regulated markets?

A: Yes. Both XRCWHT-L1-0000-002A6 and XREWHT-L1-0000-004E6 carry RoHS Compliant status and identical MSL Rating 4 specifications. Both meet regulatory requirements for restricted substance compliance and moisture sensitivity handling (72-hour exposure limit at MSL 4 conditions).

Q: What is the maximum current rating difference, and does it affect substitution?

A: The main part supports 500mA maximum current; the substitute supports 700mA maximum current. This difference does not prevent substitution. The substitute's higher current rating provides additional design margin and allows operation at higher brightness levels if required by future application modifications.
