Key Parameters

Substitute Part Grouping Explanation

The XREWHT-L1-0000-006E5 qualifies as a parametric equivalent based on the following criteria:

• Color and CCT Match: Both parts deliver neutral white light at 4000K
• Luminous Flux Equivalence: Identical flux output of 65lm at 25°C and 350mA test current
• Package Compatibility: Both use the 3529 (9073 Metric) surface mount package with identical footprint dimensions (9.00mm × 7.00mm) and seated height (4.60mm)
• Viewing Angle: Both maintain 90° viewing angle
• CRI Specification: Both rated at 75 CRI (Typ)
• Compliance Alignment: Both are RoHS Compliant with identical MSL 4 rating and REACH Unaffected status

The XR-E series represents an active product line evolution from the obsolete XR-C series, with improved electrical performance characteristics while maintaining functional output parameters.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006E5 is the appropriate substitute for the obsolete XRCWHT-L1-0000-006E5 based on the following factors:

• Product Status: The substitute is an active product line, ensuring long-term availability and supply chain continuity
• Functional Equivalence: Identical luminous flux output (65lm) and color temperature (4000K) maintain optical performance in existing circuit designs
• Compliance Certification: Both parts maintain RoHS Compliance and REACH Unaffected status, satisfying regulatory requirements
• Package Compatibility: Identical 3529 surface mount package dimensions and footprint allow direct PCB substitution without layout modifications
• Electrical Compatibility: Forward voltage difference of 0.2V (4.6V vs 3.3V) is within typical LED driver tolerance ranges; the substitute's lower voltage and improved thermal resistance (8°C/W vs 12°C/W) represent performance enhancements

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-006E5 be used as a direct replacement on existing PCBs designed for XRCWHT-L1-0000-006E5?

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

Q: What is the impact of the 0.2V forward voltage difference between these parts?

A: The XREWHT-L1-0000-006E5 operates at 3.3V typical versus 4.6V for the original part. This difference is within standard LED driver tolerance specifications and does not affect circuit functionality. Existing current-limiting designs will continue to operate within specification.

Q: Are the luminous flux outputs identical?

A: Yes. Both parts deliver 65lm (62lm ~ 67lm) at 25°C and 350mA test current, ensuring equivalent optical performance in lighting applications.

Q: What are the compliance implications of this substitution?

A: Both parts are RoHS Compliant and REACH Unaffected, maintaining identical regulatory compliance status. No compliance documentation changes are required.

Q: Does the improved thermal resistance of the substitute part affect circuit design?

A: The XREWHT-L1-0000-006E5 has superior thermal resistance (8°C/W vs 12°C/W), resulting in lower junction temperatures under identical operating conditions. This represents a performance improvement and does not require design modifications.

Q: What is the maximum current rating difference, and does it matter for my application?

A: The substitute supports 700mA maximum current versus 500mA for the original part. If your design operates at or below 500mA, this difference is not relevant. Higher current capability in the substitute provides additional design margin.

Q: Are packaging and moisture sensitivity specifications identical?

A: Yes. Both parts use MSL 4 (72 Hours) moisture sensitivity rating and are supplied in identical package configurations, maintaining equivalent handling and storage requirements.
