XRCWHT-L1-0000-00B02 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00B02 is a CreeLED XLamp® XR-C cool white LED (6350K) surface mount component rated for 350mA operation at 4.6V forward voltage. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which maintains electrical and mechanical compatibility while offering improved thermal performance and higher maximum current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00B02 is determined by the following critical parameters:

Electrical Compatibility:

• Color temperature (CCT): 6350K
• Luminous flux @ 25°C, 350mA: 97lm (94lm – 100lm)
• Test current: 350mA
• CRI: 75 (Typ)
• Viewing angle: 90°

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric)
• Physical dimensions: 0.354" L × 0.276" W (9.00mm × 7.00mm)
• Height (Max): 0.181" (4.60mm)
• Mounting type: Surface Mount

Regulatory & Environmental:

• RoHS Compliant
• MSL Rating: 4 (72 Hours)

The substitute parts listed below are from the XLamp® XR-E series, which maintains identical package geometry, luminous output, color temperature options, and compliance certifications. The primary differences are forward voltage (3.3V vs. 4.6V), improved thermal resistance (8°C/W vs. 12°C/W), and higher maximum current rating (1A vs. 500mA).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute for 6350K Applications: XREWHT-L1-0000-00B02 and XREWHT-L1-R250-00B02 are direct functional equivalents for the XRCWHT-L1-0000-00B02. Both maintain 6350K color temperature, identical luminous output (97lm @ 350mA), and mechanical compatibility. The XLamp® XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current capability (1A vs. 500mA). Forward voltage is reduced to 3.3V, which requires circuit adjustment but provides improved efficiency (84 lm/W vs. 79 lm/W).

Alternative Color Temperature Options: For applications where color temperature flexibility is acceptable, XREWHT-L1-0000-00B03 (6000K) and XREWHT-L1-0000-00BE3 (5000K) provide identical electrical performance and mechanical fit. These alternatives maintain the same luminous flux, CRI, and viewing angle specifications.

Packaging Variants: The XREWHT-L1-R250 series (XREWHT-L1-R250-00B02, XREWHT-L1-R250-00B03, XREWHT-L1-R250-00BE3) are functionally identical to their non-R250 counterparts, with differences limited to reel configuration for automated assembly processes.

Compliance & Regulatory: All substitute parts maintain RoHS Compliance and MSL Rating 4 (72 Hours), ensuring compatibility with existing manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00B02 be used as a direct replacement for XRCWHT-L1-0000-00B02?

A: Yes, with circuit adjustment. Both parts share identical package geometry (3529), luminous output (97lm @ 350mA), color temperature (6350K), and CRI (75). The primary difference is forward voltage: XREWHT operates at 3.3V versus XRCWHT at 4.6V. Current-limiting resistor or driver circuit values must be recalculated to accommodate the 0.2V reduction.

Q: What is the difference between XREWHT-L1-0000-00B02 and XREWHT-L1-R250-00B02?

A: These parts are electrically and mechanically identical. The R250 designation indicates reel configuration for automated pick-and-place assembly. Selection depends on manufacturing process requirements, not electrical performance.

Q: Can I substitute a 5000K part (XREWHT-L1-0000-00BE3) for the 6350K original?

A: Substitution is possible if application requirements permit color temperature variation. Both parts maintain identical luminous flux (97lm), CRI (75), viewing angle (90°), and mechanical fit. The 5000K variant produces warmer light output compared to the 6350K original.

Q: What are the thermal performance improvements in the XLamp® XR-E series?

A: Thermal resistance is reduced from 12°C/W (XRCWHT) to 8°C/W (XREWHT), resulting in lower junction temperature at equivalent power dissipation. This improvement enables higher maximum current operation (1A vs. 500mA) and improved long-term reliability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (XREWHT series) maintain RoHS Compliance status and MSL Rating 4 (72 Hours), matching the original XRCWHT-L1-0000-00B02 specifications.

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

A: The 0.2V reduction (4.6V to 3.3V) decreases total voltage drop across the LED. For constant-current driver circuits, this change has minimal impact. For resistor-based current limiting, recalculate series resistance using Ohm's Law: R = (Vsupply − Vf) / Iled. For example, a 5V supply with 350mA operation requires 3.43Ω (original) versus 4.86Ω (substitute).
