Engineering Selection Recommendations

All XLamp® XR-E substitutes listed are active products with RoHS compliance and identical MSL ratings, ensuring regulatory and supply continuity. The XR-E series provides measurable improvements: reduced forward voltage (3.3V vs. 4.6V), improved thermal resistance (8°C/W vs. 12°C/W), and higher maximum current capability (700mA vs. 500mA).

For applications requiring the exact 3500K color temperature of the original part, select XREWHT-L1-0000-006A6 or XREWHT-L1-R250-006A6. Both maintain identical optical and electrical performance at the 350mA test current while offering superior thermal characteristics.

For applications where color temperature flexibility exists, the full range of XR-E warm white options (2700K through 3500K) provides equivalent light output and electrical compatibility with improved efficiency and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can XLamp® XR-E parts directly replace the obsolete XLamp® XR-C part?

A: Yes. All XR-E substitutes share identical package dimensions (3529 metric), viewing angle (90°), light output at 350mA (65lm), and surface mount configuration. The 0.2V reduction in forward voltage (4.6V to 3.3V) is within typical circuit design margins and improves efficiency.

Q: What is the difference between XREWHT-L1-0000-006A6 and XREWHT-L1-R250-006A6?

A: Both parts are electrically and optically identical. The R250 designation indicates a different tape reel configuration. Selection depends on packaging and handling requirements for your manufacturing process.

Q: Why are multiple CCT options listed as substitutes?

A: The original part operates at 3500K. Substitutes at 2700K, 2850K, 3000K, and 3250K are listed as parametric equivalents because they maintain identical light output (65lm), electrical characteristics (350mA test current, 3.3V Vf), and mechanical compatibility. Select the CCT that matches your application's color temperature requirement.

Q: Does the improved thermal resistance of XR-E affect circuit design?

A: The reduction from 12°C/W to 8°C/W improves thermal performance and allows higher current operation (700mA maximum vs. 500mA). Existing designs operating at 350mA benefit from lower junction temperatures without circuit modification.

Q: Are all substitute parts available in the same packaging options?

A: The main part is supplied in standard packaging. XR-E substitutes are available in Tape & Reel (TR) configuration. Confirm packaging availability with your supplier for production requirements.
