Engineering Selection Recommendations

The XREWHT-L1-0000-004E8 is a direct substitute for the obsolete XRCWHT-L1-0000-002AA based on the following engineering factors:

Compliance & Product Status: The substitute part is Active status from CreeLED, Inc., ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS Compliance and identical MSL ratings, satisfying regulatory and manufacturing requirements.

Mechanical Compatibility: Identical package format (3529), physical dimensions (9.00mm × 7.00mm), and height (4.60mm) ensure drop-in compatibility on existing PCB layouts and assembly equipment without design modification.

Electrical Compatibility: Forward voltage differential (4.6V to 3.3V) is within acceptable operating margins for standard LED driver circuits. Both parts operate at 350mA nominal test current with compatible maximum current ratings (500mA vs. 700mA). The lower forward voltage of the substitute reduces power dissipation in series resistor networks.

Optical Compatibility: Both parts deliver 90° viewing angle and 2700K warm white color temperature. The substitute provides higher luminous flux (54 lm vs. 43 lm at 350mA) and improved efficiency (47 lm/W vs. 35 lm/W), with specified CRI of 80 typical.

Thermal Performance: The substitute exhibits superior thermal resistance (8°C/W vs. 12°C/W), enabling better heat dissipation in thermally constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004E8 be used as a direct replacement without circuit modification?

A: Yes. The substitute part maintains identical package geometry, mounting type, and viewing angle. Forward voltage difference (3.3V vs. 4.6V) is within standard LED circuit tolerance margins and does not require redesign of driver circuits or resistor networks.

Q: What is the impact of the lower forward voltage on circuit performance?

A: The 0.2V reduction in forward voltage (4.6V to 3.3V) decreases power dissipation in series current-limiting resistors. For constant-current driver circuits, this change is transparent. For resistor-based designs, recalculation of series resistance may optimize efficiency, but existing circuits will function within acceptable parameters.

Q: Are there any thermal management considerations when substituting?

A: The substitute part features improved thermal resistance (8°C/W vs. 12°C/W), resulting in lower junction temperatures under identical operating conditions. This enhancement supports higher reliability margins and does not introduce thermal compatibility issues.

Q: Does the higher maximum current rating (700mA vs. 500mA) affect substitution suitability?

A: No. The substitute part is rated for higher maximum current but operates at the same 350mA test current as the original part. The increased maximum rating provides additional design margin and does not impact compatibility at nominal operating conditions.

Q: What packaging format is available for the substitute part?

A: The XREWHT-L1-0000-004E8 is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly. Verify packaging compatibility with your procurement and assembly processes.

Q: Are both parts RoHS compliant and suitable for regulated applications?

A: Yes. Both the original XRCWHT-L1-0000-002AA and substitute XREWHT-L1-0000-004E8 are RoHS Compliant with identical MSL ratings (4, 72 Hours), meeting regulatory requirements for controlled environments.
