Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006E5 is a direct substitute for the obsolete XRCWHT-L1-0000-003B2 based on the following factors:

Mechanical Fit: Both components share identical package dimensions (3529 / 9073 Metric), footprint (9.00 mm × 7.00 mm), and seated height (4.60 mm). PCB layout and assembly tooling require no modification.

Electrical Operation: The substitute operates at 350 mA nominal current with forward voltage of 3.3 V, compared to 4.6 V for the main part. This 0.2 V difference is within acceptable tolerance for series LED circuit operation. The substitute delivers higher luminous flux (65 lm vs. 49 lm) and improved efficiency (56 lm/W vs. 40 lm/W) at identical test current.

Regulatory Compliance: Both components are RoHS Compliant with identical Moisture Sensitivity Level (MSL 4, 72 Hours), ensuring equivalent handling and storage requirements.

Product Availability: The substitute is classified as Active product status with 2132 units in stock, providing long-term sourcing stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006E5 replace XRCWHT-L1-0000-003B2 in existing designs?

A: Yes. Both components share identical mechanical dimensions, package type (3529 / 9073 Metric), and mounting configuration. No PCB redesign is required. The substitute operates at compatible voltage and current levels for direct circuit substitution.

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

A: The main part operates at 4.6 V typical, while the substitute operates at 3.3 V typical. This 0.2 V difference is within normal tolerance for LED circuit design and does not require circuit modification for series operation.

Q: Does the substitute provide equivalent light output?

A: The substitute delivers higher luminous flux (65 lm at 350 mA vs. 49 lm) and improved efficiency (56 lm/W vs. 40 lm/W). For applications requiring identical light output, circuit current may be reduced accordingly.

Q: Are there any handling or storage differences?

A: Both components have identical Moisture Sensitivity Level (MSL 4, 72 Hours) and RoHS compliance status. No changes to handling, storage, or assembly procedures are required.

Q: What is the thermal performance difference?

A: The substitute has improved thermal resistance (8°C/W vs. 12°C/W), indicating better heat dissipation. This provides thermal margin benefit in high-ambient-temperature applications.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for production assembly. The main part packaging format was not specified in the original documentation.
