Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-003A9 is based on the following criteria:

Mandatory Compatibility Parameters:

• Color temperature: 2850K warm white
• Package type: 3529 (9073 Metric) surface mount
• Viewing angle: 90°
• Mounting configuration: Surface mount, identical footprint
• Physical dimensions: 9.00mm × 7.00mm × 4.60mm maximum height
• Compliance: RoHS compliant, MSL 4 rating

Electrical Operating Range:

• Test current: 350mA nominal operation
• Forward voltage tolerance: 3.3V to 4.6V acceptable range
• Maximum current rating: minimum 500mA

The XREWHT-L1-0000-005A9 meets all mandatory compatibility parameters. Both parts share identical package geometry, color temperature specification, and mounting requirements. The substitute operates within the electrical operating envelope of the original part while offering improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-005A9 is a direct substitute for the obsolete XRCWHT-L1-0000-003A9. Both parts maintain identical package geometry, color temperature, and mounting configuration, enabling direct PCB-level replacement without layout modifications.

The substitute part is classified as active product status, ensuring continued availability and supply chain stability. Both parts carry RoHS compliance and identical MSL 4 ratings, maintaining regulatory and handling requirements.

The XREWHT-L1-0000-005A9 operates at a lower typical forward voltage (3.3V vs. 4.6V) and delivers higher luminous flux output (59lm vs. 49lm) at the same 350mA test current. The improved thermal resistance (8°C/W vs. 12°C/W) provides better heat dissipation characteristics. These performance improvements are compatible with existing circuit designs operating within the specified electrical envelope.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-005A9 be used as a direct replacement without circuit modification?

A: Yes. Both parts share identical package geometry (3529), footprint dimensions (9.00mm × 7.00mm), and mounting type. The substitute operates within the electrical operating range of the original design. The lower typical forward voltage (3.3V vs. 4.6V) and higher maximum current rating (700mA vs. 500mA) are compatible with circuits designed for the original part.

Q: What are the key differences between these parts?

A: The XREWHT-L1-0000-005A9 represents a newer generation (XR-E series vs. XR-C series) with improved efficiency. At 350mA test current, the substitute delivers 59lm compared to 49lm from the original, achieving 51 lm/W versus 40 lm/W. Thermal resistance is improved from 12°C/W to 8°C/W. Color temperature and package specifications remain identical.

Q: Are there any handling or storage differences?

A: Both parts carry MSL 4 rating with 72-hour moisture sensitivity level requirements. Handling and storage procedures are identical. No additional precautions are required when transitioning to the substitute part.

Q: What is the impact of the lower forward voltage on circuit design?

A: The substitute operates at 3.3V typical versus 4.6V for the original. This 0.2V difference falls within normal design tolerances for LED driver circuits. Existing current-limiting designs will continue to function correctly. Power consumption will be slightly reduced due to the lower voltage drop.

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

A: The substitute is available in Tape & Reel (TR) packaging. Both parts use identical 3529 surface mount package geometry, ensuring compatibility with automated assembly equipment and pick-and-place systems.
