Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00AE3 is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Color and CCT: White, Cool 5000K
• Package / Case: 3529 (9073 Metric)
• Viewing Angle: 90°
• Mounting Type: Surface Mount
• Test Current: 350mA
• Flux @ 25°C: 91lm (87lm ~ 94lm)
• CRI: 75 (Typ)

Allowable Variations:

• Forward Voltage (Vf): 4.6V (main part) to 3.3V (substitutes) — acceptable within typical LED tolerance ranges
• Maximum Current: 500mA (main part) to 1A (substitutes) — substitutes support higher current capability
• Lumens/Watt: 74 lm/W (main part) to 79 lm/W (substitutes) — improved efficiency in substitutes
• Thermal Resistance: 12°C/W (main part) to 8°C/W (substitutes) — improved thermal performance in substitutes
• Product Status: Obsolete (main part) to Active (substitutes) — substitutes remain in active production

The XLamp® XR-E series substitutes (XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3) are direct parametric equivalents that maintain identical optical and mechanical specifications while offering enhanced electrical performance and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

Both XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3 are suitable substitutes for the obsolete XRCWHT-L1-0000-00AE3. Selection between the two XLamp® XR-E substitutes depends on packaging requirements:

XREWHT-L1-0000-00AE3: Standard Tape & Reel packaging for automated assembly processes.

XREWHT-L1-R250-00AE3: Tape & Reel packaging with R250 specification, suitable for specific production line configurations.

Both substitutes maintain RoHS compliance and REACH unaffected status, consistent with the original part. The XLamp® XR-E series offers improved thermal performance (8°C/W versus 12°C/W) and higher maximum current rating (1A versus 500mA), providing enhanced reliability and design margin in thermal-constrained applications. The lower forward voltage (3.3V versus 4.6V) results in reduced power dissipation at the specified 350mA test current.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3 be used interchangeably with XRCWHT-L1-0000-00AE3?

A: Yes. Both XLamp® XR-E substitutes maintain identical optical output (91lm at 350mA), color temperature (5000K), CRI (75), viewing angle (90°), and mechanical dimensions (3529 package, 9.00mm x 7.00mm x 4.60mm max height). The forward voltage difference (3.3V versus 4.6V) is within acceptable LED operating tolerances and may reduce circuit power dissipation.

Q: What is the difference between XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3?

A: Both parts are electrically and optically identical. The difference is in packaging specification: XREWHT-L1-R250-00AE3 includes an R250 designation in the part number, indicating a specific tape and reel configuration. Selection depends on your production equipment compatibility and supply chain requirements.

Q: Why is the original XRCWHT-L1-0000-00AE3 marked as obsolete?

A: The XLamp® XR-C series has been discontinued by CreeLED in favor of the improved XLamp® XR-E series. The XR-E series provides better thermal performance, higher current capability, and improved efficiency while maintaining full compatibility with existing XR-C designs.

Q: Are there any circuit design changes required when substituting XREWHT parts for XRCWHT?

A: No circuit redesign is required. The substitutes operate at the same test current (350mA) and produce identical luminous flux (91lm). The lower forward voltage (3.3V versus 4.6V) may slightly reduce power dissipation, which is beneficial. Existing current-limiting resistor values and thermal management designs remain valid.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. Both XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3 have MSL 4 (72 Hours), identical to the original XRCWHT-L1-0000-00AE3. Identical moisture handling and storage protocols apply.

Q: What is the advantage of the improved thermal resistance in the XR-E substitutes?

A: The XLamp® XR-E series has thermal resistance of 8°C/W compared to 12°C/W in the XR-C series. This 33% improvement in thermal performance allows better heat dissipation from the LED junction, resulting in lower operating temperatures and extended component life in thermally constrained applications.
