Substitute Part Grouping Explanation

The XRCWHT-L1-0000-002E7 has one direct substitute: XREWHT-L1-0000-004E7. This substitution is valid based on the following matching criteria:

• Color temperature: Both parts are 3000K warm white
• Viewing angle: Both maintain 90° beam angle
• Package footprint: Identical 3529 (9073 Metric) surface mount package
• Mounting type: Both are surface mount devices
• CRI rating: Both specify 80 (Typical)
• Compliance: Both are RoHS Compliant with identical MSL rating

The substitute represents a generational upgrade within the XLamp® family (XR-E vs. XR-C), with improved electrical and thermal characteristics while maintaining mechanical and optical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004E7 is the designated substitute for the obsolete XRCWHT-L1-0000-002E7. Selection of this substitute is supported by:

• Active product status ensures ongoing availability and manufacturer support
• Identical package footprint (3529) and mounting type enable direct PCB compatibility without layout modifications
• Matching color temperature (3000K) and CRI (80) preserve optical performance in warm white applications
• Both parts maintain RoHS Compliance and identical MSL ratings, ensuring equivalent handling and storage requirements
• Lower forward voltage (3.3V vs. 4.6V) and improved thermal resistance (8°C/W vs. 12°C/W) provide operational advantages

Circuit designs operating at the original 350mA test current will function with the substitute. Designs utilizing the full 500mA capability of the original part may operate the substitute at higher current levels up to its 700mA maximum rating.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-004E7 be used as a direct replacement for XRCWHT-L1-0000-002E7?

A: Yes. Both parts share identical package dimensions (3529), mounting type (surface mount), color temperature (3000K), viewing angle (90°), and CRI rating (80). The substitute is mechanically and optically compatible with existing PCB designs.

Q: What are the electrical differences between these parts?

A: The substitute has a lower forward voltage (3.3V vs. 4.6V) and higher maximum current rating (700mA vs. 500mA). At the standard 350mA test current, both parts operate within their specified ranges. The substitute also provides improved thermal resistance (8°C/W vs. 12°C/W).

Q: Are there luminous flux differences?

A: Yes. At 350mA test current and 25°C, the substitute produces 54lm compared to 43lm for the original part. This represents approximately 26% higher luminous output at identical operating current.

Q: Do these parts have the same package and handling requirements?

A: Yes. Both parts use the 3529 (9073 Metric) surface mount package with identical physical dimensions and height. Both have MSL rating 4 (72 Hours) and are RoHS Compliant, requiring identical moisture control and storage protocols.

Q: What is the packaging difference?

A: The original part is supplied in bulk packaging. The substitute is supplied in Tape & Reel (TR) format, which is standard for production environments and provides improved component protection and automated handling compatibility.
