Engineering Selection Recommendations

The XREWHT-L1-0000-006A1 is the designated substitute for the obsolete XRCWHT-L1-0000-003E3. Selection is based on:

Product Status: The main part is classified as obsolete, while the substitute is active, ensuring continued availability and manufacturing support.

Regulatory Compliance: Both parts maintain RoHS Compliant status and identical MSL ratings (4, 72 Hours), confirming equivalent environmental and handling requirements.

Electrical & Mechanical Compatibility: Identical color temperature (5000K), test current (350mA), viewing angle (90°), and package geometry (3529, 9.00mm × 7.00mm × 4.60mm) ensure direct functional replacement in existing circuit designs.

Performance Characteristics: The substitute delivers higher luminous flux (65lm vs. 49lm) and improved efficacy (56 lm/W vs. 40 lm/W) at the same test current, with a lower forward voltage (3.3V vs. 4.6V) and superior thermal resistance (8°C/W vs. 12°C/W). These improvements represent generational advancement within the XLamp® product line.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-006A1 be used as a direct replacement for the XRCWHT-L1-0000-003E3?

A: Yes. Both parts share identical color temperature (5000K), test current (350mA), viewing angle (90°), and package dimensions (3529 metric, 9.00mm × 7.00mm × 4.60mm). The substitute is electrically and mechanically compatible for direct board-level substitution.

Q: What is the difference in forward voltage between these parts?

A: The main part operates at 4.6V typical, while the substitute operates at 3.3V typical. This 0.2V difference is within acceptable substitution parameters and may require minor circuit adjustments in voltage-sensitive applications.

Q: Why does the substitute have higher luminous flux output?

A: The XREWHT-L1-0000-006A1 represents a newer generation within the XLamp® product line (XR-E vs. XR-C), incorporating improved LED die technology that delivers 65lm versus 49lm at the same 350mA test current.

Q: Are the thermal characteristics different?

A: Yes. The substitute has superior thermal resistance (8°C/W vs. 12°C/W), indicating better heat dissipation performance. This improvement is typical of newer LED generations and does not affect substitution compatibility.

Q: What is the difference in packaging format?

A: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprints and can be used interchangeably in production environments.

Q: Are both parts RoHS compliant?
