Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005E3 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color and CCT: White, Cool 5000K (exact match required)
• Package / Case: 3529 (9073 Metric) (physical and electrical interface)
• Mounting Type: Surface Mount (assembly compatibility)
• Viewing Angle: 90° (optical performance)
• Test Current: 350mA nominal operation
• RoHS Compliance: Required for regulatory alignment

Allowable Variation Parameters:

• Forward Voltage (Vf): Minor variations acceptable within typical operating range
• Flux Output: Variations within acceptable lumen range for application
• Lumens/Watt Efficiency: Higher efficiency acceptable
• Thermal Resistance: Lower thermal resistance acceptable (improved thermal performance)
• CRI: Variations acceptable if not specified as critical
• Maximum Current Rating: Higher ratings acceptable

The XREWHT-L1-0000-006A1 qualifies as a direct substitute based on matching all mandatory criteria while offering improved electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006A1 is the qualified substitute for the obsolete XRCWHT-L1-0000-005E3 based on the following engineering factors:

Product Status Alignment: The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Regulatory Compliance: Both parts maintain RoHS compliance and identical MSL ratings (4, 72 Hours), ensuring equivalent handling, storage, and assembly requirements.

Electrical Compatibility: The substitute operates at a lower forward voltage (3.3V vs. 4.6V) while maintaining the same 350mA test current, resulting in improved power efficiency without requiring circuit redesign. The higher lumen output (65lm vs. 59lm) and efficiency (56 lm/W vs. 48 lm/W) represent performance improvements.

Mechanical Compatibility: Identical package dimensions (3529 / 9073 Metric), footprint, and height ensure direct PCB compatibility without layout modifications.

Thermal Performance: The improved thermal resistance (8°C/W vs. 12°C/W) provides better heat dissipation characteristics, supporting higher reliability in thermal-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-006A1 be used as a direct replacement without PCB modifications?

A: Yes. Both parts share identical package dimensions (3529 / 9073 Metric), footprint (0.354" L x 0.276" W), and height (0.181" max). No PCB layout changes are required.

Q: What is the difference in forward voltage between these parts?

A: The substitute (XREWHT-L1-0000-006A1) operates at 3.3V typical forward voltage compared to 4.6V for the main part. This 0.2V reduction improves power efficiency. Circuit designs must accommodate this voltage difference in current-limiting resistor calculations.

Q: Are the lumen outputs compatible?

A: The substitute produces 65lm (62lm ~ 67lm) at 350mA compared to 59lm (57lm ~ 62lm) for the main part. The substitute provides approximately 10% higher light output while maintaining the same 5000K color temperature and 90° viewing angle.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts are rated MSL 4 (72 Hours), requiring identical handling, storage, and reflow procedures. No changes to assembly processes are necessary.

Q: What is the thermal resistance difference?

A: The substitute has improved thermal resistance of 8°C/W compared to 12°C/W for the main part. This means the substitute dissipates heat more efficiently, reducing junction temperature rise under the same operating conditions.

Q: Is the substitute part in active production?

A: Yes. The XREWHT-L1-0000-006A1 is classified as active product status, ensuring ongoing availability and supply chain support, unlike the obsolete main part.

Q: Are both parts RoHS compliant?

A: Yes. Both the XRCWHT-L1-0000-005E3 and XREWHT-L1-0000-006A1 are RoHS compliant, meeting regulatory requirements for restricted substance elimination.
