Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-008E5 is based on the following criteria:

Mandatory Compatibility Parameters:

• Color and CCT: White, Neutral 4000K (exact match required)
• Luminous Flux @ 25°C: 77lm (74lm ~ 81lm) (exact match required)
• CRI: 75 (Typ) (exact match required)
• Viewing Angle: 90° (exact match required)
• Package / Case: 3529 (9073 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 9.00mm L x 7.00mm W x 4.60mm H (exact match required)
• RoHS Status: RoHS Compliant (exact match required)
• MSL Rating: 4 (72 Hours) (exact match required)

Allowable Variation Parameters:

• Forward Voltage (Vf): 3.3V to 4.6V (within acceptable circuit design tolerance)
• Test Current: 350mA (fixed)
• Maximum Current: 500mA to 700mA (higher maximum current provides design margin)
• Lumens per Watt: 63 to 67 lm/W (improved efficiency acceptable)
• Thermal Resistance: 8°C/W to 12°C/W (lower thermal resistance acceptable)

The two substitute parts listed (XREWHT-L1-0000-008E5 and XREWHT-L1-R250-008E5) are from the XR-E series and meet all mandatory compatibility parameters while offering improved electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are from the active XLamp® XR-E product line and carry identical RoHS and REACH compliance status as the original XRCWHT-L1-0000-008E5. The XR-E series represents the current generation replacement for the obsolete XR-C series.

XREWHT-L1-0000-008E5 and XREWHT-L1-R250-008E5 are functionally equivalent for applications requiring neutral white 4000K LEDs in the 3529 package. Both maintain the same luminous flux output (77lm) and color rendering index (75 CRI) as the original part. The primary differences are:

• Forward voltage reduced from 4.6V to 3.3V, resulting in lower power consumption
• Maximum current rating increased from 500mA to 700mA, providing additional design margin
• Thermal resistance improved from 12°C/W to 8°C/W, enabling better heat dissipation
• Lumens per watt efficiency increased from 63 to 67 lm/W

The distinction between the two substitute parts is packaging format: XREWHT-L1-0000-008E5 is supplied in Tape & Reel, while XREWHT-L1-R250-008E5 is also supplied in Tape & Reel with a different reel configuration (R250 designation).

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008E5 and XREWHT-L1-R250-008E5 be used interchangeably with XRCWHT-L1-0000-008E5?

A: Yes. Both XR-E substitutes maintain identical color temperature (4000K), luminous flux (77lm), CRI (75), viewing angle (90°), and physical package dimensions (3529 / 9073 Metric). All three parts are RoHS compliant with MSL 4 rating. The lower forward voltage (3.3V vs 4.6V) and improved thermal characteristics of the XR-E series are compatible with existing circuit designs.

Q: What is the difference between XREWHT-L1-0000-008E5 and XREWHT-L1-R250-008E5?

A: Both parts are electrically and mechanically identical. The difference is in packaging configuration. The R250 designation indicates a different reel size for automated assembly processes. Selection depends on your production equipment and tape reel compatibility requirements.

Q: Why is the forward voltage different between the main part and substitutes?

A: The XRCWHT-L1-0000-008E5 (XR-C series) operates at 4.6V typical, while the XREWHT substitutes (XR-E series) operate at 3.3V typical. This 0.2V reduction reflects improvements in the XR-E LED die design. Both values are within acceptable tolerance for standard LED circuit designs using current-limiting resistors or constant-current drivers.

Q: Are there any compliance or certification differences?

A: No. All three parts carry identical RoHS compliance, REACH unaffected status, and MSL 4 (72 Hours) moisture sensitivity ratings. ECCN and HTSUS classifications are identical.

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

A: The XR-E series thermal resistance of 8°C/W (compared to 12°C/W in XR-C) indicates more efficient heat transfer from the LED die to the package. This allows for better thermal management in applications with thermal constraints or higher ambient temperatures.

Q: Can I use these substitutes in new designs?

A: Yes. The XR-E series parts (XREWHT-L1-0000-008E5 and XREWHT-L1-R250-008E5) are active products with full production support. They are the recommended choice for new designs requiring neutral white 4000K LEDs in the 3529 package.
