Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-002F6 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color and CCT: White, Warm 3700K (must match exactly)
• Package / Case: 3529 (9073 Metric) surface mount (identical footprint and height required)
• Viewing Angle: 90° (optical performance requirement)
• Mounting Type: Surface Mount (assembly compatibility)
• RoHS Compliance: Required for regulatory alignment
• MSL Rating: 4 (72 Hours) (moisture handling during assembly)

Operational Parameters (allowable variance):

• Forward Voltage: 3.3V–4.6V range acceptable (within typical LED tolerance)
• Test Current: 350mA nominal (standard test condition)
• Maximum Current: ≥500mA (must support or exceed original specification)
• Lumens/Watt: Higher efficiency acceptable (performance improvement)
• Thermal Resistance: Lower values acceptable (improved thermal management)

The XREWHT-L1-0000-004F6 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004F6 is the designated substitute for the obsolete XRCWHT-L1-0000-002F6. Selection is based on the following engineering factors:

Product Status Alignment: The substitute part carries Active status, ensuring continued availability and supply chain stability compared to the obsolete main part.

Regulatory Compliance: Both parts maintain RoHS Compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent component selection.

Mechanical Compatibility: Identical package dimensions (3529 / 9073 Metric), footprint (9.00mm × 7.00mm), and seated height (4.60mm) ensure direct PCB assembly compatibility without design modification.

Electrical Performance: The substitute operates within acceptable voltage tolerance (3.3V vs. 4.6V), maintains identical test current (350mA), and exceeds maximum current capability (700mA vs. 500mA). These parameters support existing circuit designs without recalibration.

Optical Specifications: Matching color temperature (3700K), CRI (75 Typ), and viewing angle (90°) preserve intended lighting characteristics. The substitute delivers higher luminous flux (54 lm vs. 43 lm) and improved efficiency (47 lm/W vs. 35 lm/W), representing a performance enhancement.

Thermal Management: Improved thermal resistance (8°C/W vs. 12°C/W) provides superior heat dissipation, supporting extended operational life and reliability.

Moisture Sensitivity: Identical MSL rating (4, 72 Hours) maintains assembly process compatibility and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004F6 directly replace the XRCWHT-L1-0000-002F6 without PCB modification?

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

Q: What is the voltage difference between these parts, 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 falls within standard LED tolerance ranges and does not require circuit redesign for typical current-limiting applications.

Q: Does the substitute provide equivalent light output?

A: The substitute delivers higher luminous flux (54 lm vs. 43 lm at 350mA test current) while maintaining identical color temperature (3700K) and CRI (75). This represents a performance improvement, not a compromise.

Q: Are there any assembly or storage differences between these parts?

A: Both parts carry identical MSL rating (4, 72 Hours), requiring the same moisture control and storage protocols during assembly operations.

Q: Why is the main part classified as obsolete?

A: The XRCWHT-L1-0000-002F6 belongs to the XLamp® XR-C series, which has been superseded by newer XLamp® generations. The XR-E series substitute offers improved efficiency and thermal performance while maintaining full compatibility.

Q: Is the substitute part RoHS compliant?

A: Yes. The XREWHT-L1-0000-004F6 is RoHS Compliant and REACH Unaffected, matching the regulatory status of the main part.
