Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006E5 is the appropriate substitute for the obsolete XRCWHT-L1-0000-005E5 based on the following factors:

Product Availability: The main part is obsolete with no ongoing production. The substitute is active status with confirmed inventory (2132 pcs available).

Regulatory Compliance: Both parts maintain identical RoHS Compliant and REACH Unaffected certifications, ensuring no compliance impact in design transitions.

Electrical Performance: The substitute delivers improved performance metrics (65lm vs 59lm, 56 lm/W vs 48 lm/W) while maintaining the same color point, CRI, and viewing angle. The 0.2V lower forward voltage reduces power dissipation in series-connected applications.

Thermal Characteristics: The substitute features superior thermal resistance (8°C/W vs 12°C/W), enabling better heat management in high-density applications.

Mechanical Fit: Identical package dimensions and mounting configuration ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006E5 be used as a direct replacement in existing designs?

A: Yes. The substitute maintains identical package type (3529), physical dimensions (9.00mm x 7.00mm), and mounting configuration. No PCB layout changes are required. The 0.2V lower forward voltage may require minor current-limiting resistor adjustment in series-connected designs, but parallel and individual drive circuits require no modification.

Q: What are the key differences between the XR-C and XR-E series?

A: The XR-E series (substitute) provides higher luminous flux (65lm vs 59lm at 350mA test current) and improved efficiency (56 lm/W vs 48 lm/W). Thermal resistance is also improved (8°C/W vs 12°C/W). Color point, CRI, and viewing angle remain identical. Maximum current rating increases from 500mA to 700mA.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS Compliant status, REACH Unaffected designation, and MSL rating (4, 72 Hours). No compliance re-qualification is required for the substitution.

Q: How does the lower forward voltage (3.3V vs 4.6V) affect circuit design?

A: In series-connected LED strings, the 0.2V reduction per LED decreases total voltage drop. For example, a 10-LED string would drop 2V less. Current-limiting resistor values may require adjustment to maintain target brightness. In constant-current driver circuits, no adjustment is necessary.

Q: Is the improved thermal resistance (8°C/W vs 12°C/W) significant?

A: Yes. Lower thermal resistance improves heat dissipation from the junction to the package. This enables higher sustained current operation and reduces junction temperature rise, extending LED lifespan in thermally constrained applications.

Q: What is the inventory status for the substitute part?

A: XREWHT-L1-0000-006E5 has 2132 pcs in stock as new original inventory, ensuring availability for production and design transitions.
