XRCWHT-L1-0000-002A5 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-002A5 is an XLamp® XR-C series warm white LED (3750K) designed for surface mount applications in the 3529 (9073 Metric) package. This part is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. The XR-C series has been superseded by newer generations within the XLamp® product line, requiring engineers to evaluate functionally equivalent alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-002A5 is based on the following critical parameters:

• Color Temperature (CCT): Both parts maintain 3750K warm white specification
• Package / Case: Identical 3529 (9073 Metric) surface mount package
• Physical Dimensions: Matching footprint (9.00mm x 7.00mm) and height (4.60mm max)
• Mounting Type: Both are surface mount components
• Viewing Angle: Consistent 90° specification
• Compliance: Both parts are RoHS Compliant with identical MSL ratings

The XREWHT-L1-0000-006A5 represents the direct successor within the XLamp® product family, utilizing the XR-E generation while maintaining mechanical and thermal interface compatibility with the original XR-C design.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006A5 is the designated substitute for the obsolete XRCWHT-L1-0000-002A5. Selection is supported by:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity
• Identical Mechanical Interface: Matching package dimensions and mounting footprint enable direct PCB compatibility without layout modifications
• Regulatory Compliance: Both parts maintain RoHS Compliance and REACH Unaffected status, satisfying equivalent environmental and safety requirements
• Thermal Performance: The substitute exhibits improved thermal resistance (8°C/W vs. 12°C/W), providing enhanced thermal management in the same package envelope
• Electrical Compatibility: Forward voltage differential (3.3V vs. 4.6V) is within typical circuit design tolerance for LED driver circuits operating at 350mA test current

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-006A5 be used as a direct replacement on existing PCBs designed for the XRCWHT-L1-0000-002A5?

A: Yes. Both parts use the identical 3529 (9073 Metric) package with matching footprint dimensions (9.00mm x 7.00mm) and seated height (4.60mm). No PCB layout modifications are required.

Q: What is the impact of the forward voltage difference (4.6V vs. 3.3V)?

A: The 0.2V difference is typical between LED generations and falls within standard LED driver circuit design margins. Verify that your current-limiting circuit can accommodate the lower forward voltage of the substitute without exceeding maximum current specifications.

Q: Are there differences in color temperature or light output characteristics?

A: Both parts maintain the same 3750K warm white color temperature specification. The substitute delivers higher luminous flux (65lm vs. 43lm at 350mA), resulting in improved efficiency (56 lm/W vs. 35 lm/W). This represents a performance enhancement rather than a deviation.

Q: What is the significance of the thermal resistance improvement?

A: The substitute's lower thermal resistance (8°C/W vs. 12°C/W) indicates improved heat dissipation from the die to the package. This allows for better thermal management in applications with thermal constraints or higher ambient temperatures.

Q: Are moisture sensitivity and compliance certifications equivalent?

A: Yes. Both parts carry identical MSL ratings (4, 72 Hours), RoHS Compliance status, and REACH Unaffected designation. Storage and handling requirements are equivalent.

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

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for production environments. Confirm packaging requirements with your procurement specifications if alternative formats are needed.
