Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00302 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must maintain White, Cool 6350K specification for color consistency in lighting applications
• Package and Mounting: Identical 3529 (9073 Metric) surface mount package ensures mechanical and thermal compatibility
• Physical Dimensions: Matching footprint (9.00mm x 7.00mm) and height (4.60mm max) for PCB layout compatibility
• Electrical Interface: Forward voltage and current ratings must be compatible with existing circuit designs
• Compliance Standards: RoHS compliance and MSL rating must be maintained for manufacturing and storage requirements

The XREWHT-L1-0000-00602 qualifies as a direct substitute based on these parameters. Both components share identical package geometry, color specification, and compliance certifications, while operating within compatible electrical parameters for the same application class.

Engineering Selection Recommendations

The XREWHT-L1-0000-00602 is the qualified substitute for the obsolete XRCWHT-L1-0000-00302. Selection is based on the following engineering criteria:

• Product Status: The substitute is Active, ensuring ongoing availability and manufacturing support, whereas the main part is Obsolete
• Compliance Alignment: Both components maintain identical RoHS compliance and REACH unaffected status, meeting regulatory requirements
• Moisture Sensitivity: Matching MSL 4 (72 Hours) rating ensures compatible handling, storage, and manufacturing processes
• Package Compatibility: Identical 3529 (9073 Metric) package and physical dimensions enable direct PCB layout compatibility without redesign
• Color and CCT Consistency: Both parts deliver White, Cool 6350K specification, maintaining color uniformity in lighting applications
• Electrical Compatibility: The substitute operates at 3.3V typical forward voltage compared to 4.6V, with identical 350mA test current and 90° viewing angle, suitable for circuit adaptation

The XREWHT-L1-0000-00602 demonstrates improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficiency (56 lm/W vs. 40 lm/W), providing enhanced performance characteristics within the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-00602 be used as a direct replacement for the XRCWHT-L1-0000-00302?

A: Yes. Both components share identical package geometry (3529 / 9073 Metric), color specification (White, Cool 6350K), and compliance certifications (RoHS, REACH). The substitute operates at 3.3V forward voltage versus 4.6V, requiring circuit verification for voltage compatibility.

Q: What are the key differences between these two parts?

A: The substitute (XREWHT-L1-0000-00602) is from the XLamp® XR-E series with Active product status, compared to the obsolete XLamp® XR-C series. The substitute delivers higher luminous flux (65lm vs. 49lm) and efficiency (56 lm/W vs. 40 lm/W) at the same test current, with improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (1A vs. 500mA).

Q: Are the physical dimensions identical?

A: Yes. Both components have identical dimensions of 0.354" L x 0.276" W (9.00mm x 7.00mm) and maximum seated height of 0.181" (4.60mm), enabling direct PCB footprint compatibility.

Q: What is the forward voltage difference, and does it affect circuit design?

A: The substitute operates at 3.3V typical forward voltage compared to 4.6V for the main part. This 0.2V difference requires circuit verification to ensure proper current limiting and power supply compatibility. Existing current-limiting resistor values may require adjustment.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both components have MSL 4 (72 Hours) rating, ensuring identical handling, storage, and manufacturing process requirements.

Q: Can I use the substitute in high-current applications?

A: The substitute supports a maximum current of 1A compared to 500mA for the main part, providing greater current capacity. However, application suitability depends on thermal management and circuit design requirements.
