LED XLAMP COOL WHITE 6350K SMD XRCWHT-L1-0000-00502 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00502 is a CreeLED XLamp® XR-C series cool white LED (6350K) designed for surface mount applications. This component delivers 59 lumens at 350mA with a forward voltage of 4.6V and is housed in a 3529 (9073 Metric) package. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications requiring equivalent cool white LED performance in the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

The XREWHT-L1-0000-00602 qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Color and CCT: Both White, Cool 6350K
• Package / Case: Identical 3529 (9073 Metric) footprint
• Size / Dimension: Identical 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): Identical 0.181" (4.60mm)
• Viewing Angle: Identical 90°
• Mounting Type: Both Surface Mount
• CRI: Identical 75 (Typ)
• Test Current: Identical 350mA
• RoHS Status: Both RoHS Compliant
• MSL: Identical 4 (72 Hours)

Allowable Variations:

• Forward Voltage: 4.6V (main) vs. 3.3V (substitute) — within acceptable tolerance for cool white LED applications
• Flux Output: 59lm (main) vs. 65lm (substitute) — substitute provides higher luminous output at identical test current
• Lumens/Watt: 48 lm/W (main) vs. 56 lm/W (substitute) — improved efficiency
• Thermal Resistance: 12°C/W (main) vs. 8°C/W (substitute) — superior thermal performance
• Current - Max: 500mA (main) vs. 1A (substitute) — substitute supports higher maximum current
• Product Status: Obsolete (main) vs. Active (substitute) — substitute is in active production

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-00602 is the appropriate substitute for the obsolete XRCWHT-L1-0000-00502. Both components maintain identical package geometry, electrical test conditions, and compliance certifications (RoHS Compliant, REACH Unaffected, MSL 4). The substitute operates at a lower forward voltage (3.3V vs. 4.6V) and delivers higher luminous output (65lm vs. 59lm) at the same test current, with improved thermal characteristics (8°C/W vs. 12°C/W). The substitute's active product status ensures ongoing availability and supply chain continuity. Both components are suitable for direct PCB replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-00602 be used as a direct replacement for the XRCWHT-L1-0000-00502?

A: Yes. Both components share identical package dimensions (3529 / 9073 Metric), footprint, height, color temperature (6350K), viewing angle (90°), and test current (350mA). The substitute is electrically and mechanically compatible for direct PCB replacement.

Q: What are the key differences between these two parts?

A: The substitute operates at a lower forward voltage (3.3V vs. 4.6V), produces higher luminous flux (65lm vs. 59lm) at identical test current, exhibits superior thermal resistance (8°C/W vs. 12°C/W), and supports higher maximum current (1A vs. 500mA). The substitute is in active production status, whereas the main part is obsolete.

Q: Will the lower forward voltage of the substitute affect circuit performance?

A: The 0.2V difference (4.6V to 3.3V) is within normal operating tolerance for cool white LED applications. Circuit designs using current-limiting resistors or constant-current drivers will accommodate this variation without performance degradation.

Q: Are both parts RoHS compliant?

A: Yes. Both the XRCWHT-L1-0000-00502 and XREWHT-L1-0000-00602 are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for electronic component use.

Q: What is the moisture sensitivity level for these components?

A: Both components have MSL 4 (Moisture Sensitivity Level 4), requiring storage at controlled humidity for 72 hours maximum before soldering.

Q: Can the substitute handle higher current than the original part?

A: Yes. The substitute supports a maximum current of 1A compared to the original part's 500mA maximum. However, both are tested and specified at 350mA, which remains the standard operating point for this application category.
