Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-002F8 is determined by the following mandatory parameters:

• Color Temperature Match: 2900K warm white specification must be maintained
• Package Compatibility: 3529 (9073 Metric) surface mount package required for PCB footprint alignment
• Mechanical Dimensions: Identical physical envelope (9.00mm x 7.00mm x 4.60mm max height)
• Electrical Interface: Forward voltage and current ratings must be compatible with existing circuit design
• Viewing Angle: 90° specification for optical performance consistency
• Compliance Requirements: RoHS compliance and MSL rating must meet or exceed original specification

The XREWHT-L1-0000-004F8 qualifies as a direct substitute based on matching all mandatory parameters while offering improved performance metrics in the active product line.

Engineering Selection Recommendations

The XREWHT-L1-0000-004F8 is the qualified substitute for the obsolete XRCWHT-L1-0000-002F8. Selection is based on:

• Product Status: The substitute is active in the CreeLED product line, ensuring continued availability and supply chain stability
• Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, meeting regulatory and manufacturing requirements
• Mechanical Compatibility: Identical package dimensions and mounting type enable direct PCB footprint substitution without layout modifications
• Electrical Compatibility: The substitute operates at 3.3V typical forward voltage (0.2V lower than original) at the same 350mA test current, requiring circuit verification for voltage-dependent applications
• Performance Enhancement: The substitute delivers 25.6% higher luminous flux (54lm vs 43lm) and 34.3% higher efficacy (47 lm/W vs 35 lm/W) at identical test conditions
• Thermal Improvement: Reduced thermal resistance (8°C/W vs 12°C/W) provides superior heat dissipation characteristics

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004F8 be used as a direct replacement without circuit modifications?

A: Mechanical and thermal compatibility is direct. Electrical compatibility requires verification of the 0.2V forward voltage difference. Circuits designed for 4.6V operation will function with 3.3V, but designs with tight voltage tolerances or current-limiting resistors must be evaluated.

Q: Are the package dimensions identical between the original and substitute?

A: Yes. Both parts use the 3529 (9073 Metric) surface mount package with identical physical dimensions (9.00mm L x 7.00mm W x 4.60mm H maximum). PCB footprints are directly compatible.

Q: What is the significance of the improved thermal resistance in the substitute?

A: The XREWHT-L1-0000-004F8 features 8°C/W thermal resistance compared to 12°C/W in the original. This 33% improvement in thermal performance reduces junction temperature rise under identical operating conditions, extending component life and improving reliability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the XRCWHT-L1-0000-002F8 and XREWHT-L1-0000-004F8 are RoHS compliant with MSL rating 4 (72 Hours), meeting identical regulatory and manufacturing requirements.

Q: Why does the substitute have higher maximum current rating (700mA vs 500mA)?

A: The XR-E series (substitute) represents a newer generation with improved thermal and electrical characteristics. The higher maximum current rating reflects enhanced design capabilities, though operation at 350mA test current remains the standard specification for both parts.

Q: Is the color temperature identical between both parts?

A: Yes. Both parts are specified at 2900K warm white color temperature with CRI 80 (Typical), ensuring identical color characteristics for lighting applications.
