Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-003A5 is determined by the following critical parameters:

• Color temperature: 3750K warm white (must match)
• Package / Case: 3529 (9073 Metric) surface mount (must match)
• Viewing angle: 90° (must match)
• Mounting type: Surface mount (must match)
• Compliance: RoHS compliant and REACH unaffected status (must match)

The XREWHT-L1-0000-006A5 qualifies as a direct substitute based on identical color temperature, package dimensions, viewing angle, and compliance certifications. While this substitute operates at a lower forward voltage (3.3V vs. 4.6V) and delivers higher luminous flux (65 lm vs. 49 lm), both parameters remain within the allowable electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-006A5 is the qualified substitute for the obsolete XRCWHT-L1-0000-003A5. Selection is based on:

• Active product status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity.
• Identical compliance certifications: Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements.
• Mechanical compatibility: Identical package dimensions (3529 / 9073 Metric), footprint (9.00 mm × 7.00 mm), and height (4.60 mm) ensure direct PCB compatibility without layout modifications.
• Electrical compatibility: Both parts operate at 350mA test current and 90° viewing angle. The substitute's lower forward voltage (3.3V vs. 4.6V) and improved thermal resistance (8°C/W vs. 12°C/W) represent performance enhancements within the allowable parameter range.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-006A5 be used as a direct replacement for the XRCWHT-L1-0000-003A5 without circuit modifications?

A: Yes. Both parts share identical package dimensions, footprint, and electrical test current (350mA). The substitute's lower forward voltage (3.3V vs. 4.6V) and higher luminous flux (65 lm vs. 49 lm) are compatible with standard LED driver circuits designed for the 3750K warm white category.

Q: What is the significance of the different forward voltages?

A: The XREWHT-L1-0000-006A5 operates at 3.3V typical forward voltage compared to 4.6V for the main part. This 0.2V difference reflects the XR-E series design and does not prevent substitution. LED driver circuits typically accommodate forward voltage variations within this range.

Q: Are the thermal characteristics different between these parts?

A: Yes. The substitute exhibits improved thermal resistance (8°C/W vs. 12°C/W), indicating better heat dissipation. This represents a performance advantage and does not restrict substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the XRCWHT-L1-0000-003A5 and XREWHT-L1-0000-006A5 are RoHS compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Why is the main part classified as obsolete?

A: The XRCWHT-L1-0000-003A5 belongs to the XLamp® XR-C series, which has been superseded by the XLamp® XR-E series. The XREWHT-L1-0000-006A5 represents the current generation equivalent with improved efficiency and thermal performance.

Q: Can the substitute be used in existing designs without PCB layout changes?

A: Yes. Identical package dimensions (3529 / 9073 Metric), footprint (9.00 mm × 7.00 mm), and mounting height (4.60 mm) ensure direct compatibility with existing PCB layouts.
