LED XLAMP COOL WHITE 6350K - XRCWHT-L1-0000-00402 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00402 is a CreeLED XLamp® XR-C series cool white LED (6350K) designed for surface mount applications in the 3529 (9073 Metric) package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and design continuity. The XR-C series has been superseded by newer generations within the XLamp® product line, requiring engineers to evaluate compatible substitutes that maintain electrical and mechanical compatibility while meeting current availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00402 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color and Correlated Color Temperature (CCT): White, Cool 6350K
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Viewing Angle: 90°
• RoHS Compliance: Required
• MSL Rating: 4 (72 Hours)

Allowable Variation Parameters:

• Forward Voltage (Vf): Substitutes may vary within typical operating ranges
• Test Current: Substitutes must support 350mA operation
• Flux Output: Substitutes may exceed the original specification
• Lumens/Watt Efficiency: Substitutes may provide improved efficiency
• CRI: Substitutes must maintain 75 or higher
• Maximum Current Rating: Substitutes may exceed original specification

The XREWHT-L1-0000-00602 (XLamp® XR-E series) qualifies as a direct substitute based on matching all mandatory criteria while providing improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-00602 is the qualified substitute for the obsolete XRCWHT-L1-0000-00402 based on the following engineering criteria:

Compliance & Regulatory Alignment: Both components maintain identical RoHS compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory continuity in design transitions.

Mechanical & Thermal Compatibility: Identical package dimensions (3529 / 9073 Metric), mounting type (Surface Mount), and physical footprint ensure direct PCB compatibility without layout modifications. The substitute's improved thermal resistance (8°C/W vs. 12°C/W) provides enhanced thermal performance in the same form factor.

Electrical Performance: The substitute operates at a lower typical forward voltage (3.3V vs. 4.6V), which is within acceptable operating tolerance for most LED driver circuits. The substitute's higher maximum current rating (1A vs. 500mA) provides additional design margin without affecting standard 350mA operation.

Optical & Photometric Equivalence: Both components deliver identical color temperature (6350K), viewing angle (90°), and color rendering index (75 Typ). The substitute's higher luminous flux (65lm vs. 54lm at 350mA) and improved efficiency (56 lm/W vs. 44 lm/W) represent performance enhancements rather than deviations.

Product Status & Availability: The substitute is in active production status, ensuring long-term supply chain stability compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-00602 be used as a direct replacement without circuit modifications?

A: Yes. The substitute maintains identical package dimensions, mounting type, and electrical operating parameters at the standard 350mA test current. The 0.2V lower forward voltage (3.3V vs. 4.6V) is within typical LED driver tolerance and does not require circuit redesign for most applications.

Q: What is the impact of the higher luminous flux in the substitute?

A: The substitute delivers 20% higher flux output (65lm vs. 54lm) at identical test current. This represents an improvement in light output and does not create compatibility issues. Applications requiring the original brightness specification should evaluate whether the increased output is acceptable for their design.

Q: Are there any thermal management differences between the original and substitute?

A: The substitute provides superior thermal performance with lower thermal resistance (8°C/W vs. 12°C/W). This allows for better heat dissipation in the same package size, which is beneficial for high-reliability applications and extended operating life.

Q: Do both components have identical moisture sensitivity requirements?

A: Yes. Both components are rated MSL 4 (72 Hours), requiring identical moisture control and handling procedures during storage, transport, and assembly.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original component packaging format was not specified in the available data. Confirm packaging requirements with your procurement department.

Q: What is the basis for the color temperature equivalence?

A: Both components are specified as White, Cool 6350K, meeting identical color temperature requirements. The CRI (Color Rendering Index) is also identical at 75 Typ, ensuring color rendering consistency.

Q: Can the substitute be used in existing designs without PCB layout changes?

A: Yes. Identical physical dimensions (9.00mm x 7.00mm footprint, 4.60mm seated height) and Surface Mount package type ensure direct PCB compatibility without layout modifications.
