XRCWHT-L1-0000-007F6 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-007F6 is a warm white LED from CreeLED's XLamp® XR-C series, rated at 3700K color temperature with 4.6V forward voltage and 350mA test current. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which maintains electrical and optical compatibility while offering improved thermal characteristics and extended current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-007F6 is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Color and CCT: White, Warm 3700K
• Flux output: 71lm (67lm ~ 74lm) at 25°C, 350mA test current
• CRI: 75 (Typ)
• Viewing Angle: 90°
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Physical dimensions: 0.354" L x 0.276" W, 0.181" max height
• RoHS Compliance: Required
• MSL Rating: 4 (72 Hours)

Allowable Variation Parameters:

• Forward Voltage (Vf): 4.6V (main part) to 3.3V (substitute parts) — acceptable within typical LED tolerance ranges
• Maximum Current: 500mA (main part) to 700mA (substitute parts) — higher rating provides design margin
• Thermal Resistance: 12°C/W (main part) to 8°C/W (substitute parts) — improved thermal performance
• Lumens/Watt: 58 lm/W (main part) to 61 lm/W (substitute parts) — improved efficiency
• Series: XLamp® XR-C (main part) to XLamp® XR-E (substitute parts) — generational upgrade within same product family
• Product Status: Obsolete (main part) to Active (substitute parts) — ensures ongoing availability

Both substitute parts (XREWHT-L1-0000-007F6 and XREWHT-L1-R250-007F6) are from the XLamp® XR-E series and meet all mandatory parameters while offering improved electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The XRCWHT-L1-0000-007F6 is classified as obsolete and should be replaced with one of the two XLamp® XR-E equivalents for new designs and production continuity. Both substitute parts maintain full compliance with RoHS and REACH regulations, matching the original part's environmental certifications.

XREWHT-L1-0000-007F6 and XREWHT-L1-R250-007F6 are functionally equivalent and interchangeable from an electrical and optical standpoint. The primary distinction between these two substitutes is packaging: XREWHT-L1-0000-007F6 is supplied in standard Tape & Reel format, while XREWHT-L1-R250-007F6 is also supplied in Tape & Reel with a 250-unit reel configuration. Selection between these two should be based on procurement volume and supply chain requirements rather than technical performance.

The XLamp® XR-E series offers measurable improvements over the obsolete XR-C series: reduced forward voltage (3.3V vs. 4.6V), improved efficiency (61 lm/W vs. 58 lm/W), enhanced thermal performance (8°C/W vs. 12°C/W), and higher maximum current rating (700mA vs. 500mA). These improvements provide better thermal management and design flexibility for existing applications.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007F6 or XREWHT-L1-R250-007F6 be used as direct replacements for XRCWHT-L1-0000-007F6?

A: Yes. Both XLamp® XR-E substitutes maintain identical optical output (71lm at 3700K), CRI (75), viewing angle (90°), and physical package dimensions (3529 / 9073 Metric). The lower forward voltage (3.3V vs. 4.6V) and improved thermal characteristics make them suitable direct replacements in existing designs.

Q: What is the difference between XREWHT-L1-0000-007F6 and XREWHT-L1-R250-007F6?

A: Both parts are electrically and optically identical. The difference is in packaging configuration: XREWHT-L1-0000-007F6 uses standard Tape & Reel packaging, while XREWHT-L1-R250-007F6 uses a 250-unit reel configuration. Selection depends on procurement volume and assembly line requirements.

Q: Will the lower forward voltage of the XR-E series affect circuit design?

A: The forward voltage reduction from 4.6V to 3.3V is within typical LED tolerance ranges and should not require circuit redesign. However, current-limiting resistor values may require minor adjustment to maintain identical current levels if precise current control is critical to the application.

Q: Are the substitute parts available in the same packaging format?

A: Yes. Both XREWHT-L1-0000-007F6 and XREWHT-L1-R250-007F6 are supplied in Tape & Reel (TR) format, maintaining compatibility with standard SMD assembly equipment used for the original XRCWHT-L1-0000-007F6.

Q: Do the substitute parts meet the same environmental and compliance standards?

A: Yes. Both XLamp® XR-E substitutes are RoHS Compliant, REACH Unaffected, and carry the same MSL Rating 4 (72 Hours) as the original part, ensuring full compliance with applicable regulations and handling requirements.

Q: Why does the XR-E series have a higher maximum current rating?

A: The XLamp® XR-E series incorporates improved thermal design and materials, enabling a higher maximum current rating (700mA vs. 500mA). This provides additional design margin and flexibility for applications requiring higher brightness or current headroom.
