Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-005A7 is the qualified substitute for the obsolete XRCWHT-L1-0000-004A8 based on the following engineering criteria:

Product Status: The substitute part carries Active product status, ensuring long-term availability and manufacturing support compared to the obsolete main part.

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

Mechanical Interchangeability: Identical package type (3529), footprint dimensions (9.00mm x 7.00mm), and seated height (4.60mm) ensure direct PCB layout compatibility without redesign.

Electrical Operation: The substitute operates at 3.3V typical forward voltage versus 4.6V for the main part, representing a 0.2V reduction within acceptable circuit design margins. Both parts function at the standard 350mA test current and support the same 90° viewing angle specification.

Thermal Performance: The substitute demonstrates improved thermal resistance (8°C/W versus 12°C/W), providing enhanced heat dissipation characteristics for equivalent or improved operational reliability.

Color Temperature Consideration: The substitute operates at 3250K versus 3000K for the main part. This 250K shift remains within the warm white spectrum and is typical for component evolution within the same color family.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005A7 be used as a direct replacement for XRCWHT-L1-0000-004A8 without circuit modifications?

A: Yes. Both parts share identical mechanical specifications (3529 package, 9.00mm x 7.00mm footprint, 4.60mm height) and operate at the same 350mA test current with compatible forward voltage ranges (3.3V to 4.6V). No PCB layout changes are required.

Q: What is the impact of the 250K color temperature difference (3000K to 3250K)?

A: The shift from 3000K to 3250K represents a minor increase in correlated color temperature within the warm white spectrum. Both values fall within standard warm white lighting classifications and are visually similar to human perception. Application-specific color matching requirements should be evaluated based on end-use specifications.

Q: Why does the substitute part have higher luminous flux (59lm vs 54lm) at the same current?

A: The XREWHT-L1-0000-005A7 represents a newer generation in the XLamp® product line (XR-E series versus XR-C series) with improved photometric efficiency, delivering 51 lm/W compared to 44 lm/W for the main part. This efficiency gain is a result of manufacturing process improvements and does not affect electrical compatibility.

Q: Are the thermal characteristics of the substitute suitable for high-current applications?

A: The substitute part supports a maximum current rating of 700mA (versus 500mA for the main part) and exhibits superior thermal resistance (8°C/W versus 12°C/W). These characteristics make the substitute suitable for applications requiring higher current operation or improved thermal management.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the XRCWHT-L1-0000-004A8 and XREWHT-L1-0000-005A7 are RoHS Compliant, REACH Unaffected, and carry MSL 4 (72 Hours) moisture sensitivity ratings. Compliance requirements are equivalent for both parts.

Q: What is the primary reason for substitution?

A: The main part is classified as obsolete product status. The substitute part is active, ensuring continued availability, manufacturing support, and supply chain reliability for new production and system updates.
