LED XLAMP WARM WHITE 3500K SMD XRCWHT-L1-0000-002E6 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-002E6 is a CreeLED XLamp® XR-C series warm white LED (3500K) designed for surface mount applications in the 3529 (9073 Metric) package. This component operates at 4.6V forward voltage with a 350mA test current, delivering 43 lumens at 25°C and 35 lm/W efficiency. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing production, maintenance, and design updates. Equivalent parts must maintain identical color temperature, viewing angle, package dimensions, and mounting compatibility while meeting RoHS and REACH compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-002E6 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color and CCT: White, Warm 3500K (exact match required)
• Viewing Angle: 90° (exact match required)
• Package / Case: 3529 (9073 Metric) (exact match required)
• Mounting Type: Surface Mount (SMD) (exact match required)
• Physical Dimensions: 0.354" L × 0.276" W, Height 0.181" max (exact match required)
• RoHS and REACH Compliance: Both certifications must be maintained

Allowable Variation Parameters:

• Forward Voltage (Vf): May vary within typical operating range (3.3V–4.6V acceptable)
• Test Current: 350mA standard; maximum current rating may differ
• Flux Output: May exceed original specification (higher lumens acceptable)
• Lumens/Watt Efficiency: May exceed original specification (higher lm/W acceptable)
• Thermal Resistance: May be lower (improved thermal performance acceptable)
• Series Designation: May differ (XR-C to XR-E transition acceptable if all other parameters align)

The XREWHT-L1-0000-004E6 qualifies as a direct substitute based on identical color temperature, viewing angle, package dimensions, and compliance certifications, with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004E6 is a direct substitute for the obsolete XRCWHT-L1-0000-002E6. Both components are manufactured by CreeLED, Inc., maintain identical color temperature (3500K), viewing angle (90°), package dimensions (3529 / 9073 Metric), and compliance certifications (RoHS Compliant, REACH Unaffected).

The substitute part offers improved performance characteristics: higher luminous flux (54 lm vs. 43 lm at 350mA), superior efficiency (47 lm/W vs. 35 lm/W), lower forward voltage (3.3V vs. 4.6V), higher maximum current rating (700mA vs. 500mA), and improved thermal resistance (8°C/W vs. 12°C/W). The substitute maintains active product status, ensuring ongoing availability and supply chain continuity.

Both components share identical moisture sensitivity level (MSL 4, 72 Hours) and are suitable for direct PCB assembly replacement without circuit redesign. The lower forward voltage of the substitute may result in reduced power dissipation in constant-current drive applications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004E6 be used as a direct replacement for the XRCWHT-L1-0000-002E6 without PCB modifications?

A: Yes. Both components use the identical 3529 (9073 Metric) package with matching physical dimensions (0.354" L × 0.276" W, 0.181" max height) and surface mount configuration. No PCB layout changes are required.

Q: What is the impact of the 0.2V forward voltage difference (4.6V vs. 3.3V)?

A: In constant-current drive circuits, the lower forward voltage of the substitute reduces power dissipation by approximately 6% at 350mA test current. In constant-voltage applications, circuit current may increase slightly; current-limiting resistor values should be recalculated if applicable.

Q: Are the color rendering and color temperature identical between the two parts?

A: Yes. Both components are specified as White, Warm 3500K with CRI 80 (Typ). Color output is equivalent.

Q: Why does the substitute have a higher maximum current rating (700mA vs. 500mA)?

A: The XREWHT-L1-0000-004E6 (XR-E series) represents a newer generation LED technology with improved thermal management (8°C/W vs. 12°C/W). The higher current rating reflects enhanced thermal performance and junction design.

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

A: The substitute is supplied in Tape & Reel (TR) format. The original part packaging was not specified in the data provided. Confirm packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are RoHS Compliant and REACH Unaffected. Moisture sensitivity level is identical (MSL 4, 72 Hours).

Q: What is the luminous flux difference, and does it affect circuit design?

A: The substitute delivers 54 lm at 350mA compared to 43 lm for the original part—a 25.6% increase. In brightness-critical applications, this may require optical design adjustments (lens selection, reflector geometry) to maintain target illumination levels. In applications where higher brightness is acceptable, no changes are necessary.
