Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005E8 is determined by the following critical parameters:

• Color Temperature: 2700K warm white (must match exactly)
• Package / Case: 3529 (9073 Metric) surface mount (must match exactly)
• Viewing Angle: 90° (must match exactly)
• CRI: 80 Typ (must match exactly)
• Flux Output: 59lm nominal at 350mA test current (must match exactly)
• Mounting Type: Surface Mount (must match exactly)

The two substitute parts listed below are from the XLamp® XR-E series, which maintains identical mechanical footprint, optical characteristics, and luminous output while offering improved electrical performance and active product status. Both substitutes operate at 3.3V typical forward voltage (compared to 4.6V for the main part) and support higher maximum current ratings (700mA vs. 500mA).

Parameter Comparison

Engineering Selection Recommendations

Both XREWHT-L1-0000-005E8 and XREWHT-L1-R250-005E8 are direct functional equivalents for the obsolete XRCWHT-L1-0000-005E8. Selection between the two XLamp® XR-E substitutes depends on packaging requirements: XREWHT-L1-0000-005E8 is supplied in standard packaging, while XREWHT-L1-R250-005E8 is supplied in Tape & Reel (TR) format for automated assembly.

Both substitutes maintain RoHS compliance and REACH unaffected status, ensuring regulatory continuity. The XLamp® XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current capability (700mA vs. 500mA), with identical luminous output and color characteristics at the 350mA test current. Forward voltage reduction from 4.6V to 3.3V requires circuit evaluation to confirm compatibility with existing power supply designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005E8 or XREWHT-L1-R250-005E8 be used as direct drop-in replacements for XRCWHT-L1-0000-005E8?

A: Both XLamp® XR-E parts are mechanically and optically compatible. The 3529 package footprint, viewing angle, luminous output, and color temperature are identical. Circuit design must account for the 0.2V reduction in typical forward voltage (4.6V to 3.3V) to ensure proper current limiting and power supply compatibility.

Q: What is the difference between XREWHT-L1-0000-005E8 and XREWHT-L1-R250-005E8?

A: Both parts are electrically and optically identical. The primary difference is packaging: XREWHT-L1-0000-005E8 uses standard packaging, while XREWHT-L1-R250-005E8 is supplied in Tape & Reel (TR) format optimized for automated pick-and-place assembly. Select based on assembly process requirements.

Q: Why is the XRCWHT-L1-0000-005E8 obsolete?

A: The XLamp® XR-C series has been superseded by the XLamp® XR-E series. The XR-E generation offers improved performance metrics including better thermal characteristics and higher maximum current ratings while maintaining backward compatibility with existing designs.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts maintain identical RoHS compliance, REACH unaffected status, MSL rating (4), and ECCN/HTSUS classifications. Regulatory and environmental compliance requirements are fully satisfied by either substitute.

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

A: The 0.2V reduction in typical forward voltage (4.6V to 3.3V) affects current limiting calculations. Existing series resistor values or current-limiting circuits designed for 4.6V operation will deliver slightly higher current at the same supply voltage. Circuit simulation or testing is necessary to confirm the new operating point remains within acceptable limits for your specific application.
