LED XLAMP WARM WHITE XRCWHT-L1-0000-002B5 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-002B5 is a surface-mount LED from CreeLED's XLamp® XR-C series, designed for warm white lighting applications. This component operates at 4.6V with a 350mA test current, delivering 43 lumens at 25°C in a compact 3529 (9073 Metric) package with a 90° viewing angle. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

The XREWHT-L1-0000-004E8 qualifies as a substitute for the XRCWHT-L1-0000-002B5 based on the following critical parameters:

Mechanical Compatibility:

• Identical package type: 3529 (9073 Metric)
• Identical physical dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Identical maximum seated height: 0.181" (4.60mm)
• Both are surface-mount devices with SMD supplier packaging

Electrical Compatibility:

• Forward voltage (Vf) within acceptable range: 3.3V vs. 4.6V (0.2V difference)
• Test current identical: 350mA
• Maximum current rating higher on substitute: 700mA vs. 500mA (provides operational margin)
• Viewing angle identical: 90°

Regulatory & Environmental Compliance:

• Both RoHS Compliant
• Both REACH Unaffected
• Both MSL 4 (72 Hours)
• Both ECCN EAR99 classification

The substitute part operates at slightly lower forward voltage (3.3V) while maintaining the same test current, and delivers higher luminous flux (54lm vs. 43lm) with improved efficiency (47 lm/W vs. 35 lm/W).

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004E8 is the designated substitute for the obsolete XRCWHT-L1-0000-002B5. Both components maintain identical mechanical compatibility through the 3529 (9073 Metric) package specification and are fully interchangeable at the PCB level.

The substitute part offers operational advantages: lower forward voltage (3.3V vs. 4.6V) reduces power dissipation in series-resistor circuits, higher maximum current rating (700mA vs. 500mA) provides design margin, and improved thermal resistance (8°C/W vs. 12°C/W) enhances thermal performance. The substitute delivers 25.6% higher luminous flux at identical test current.

Both components satisfy identical regulatory requirements: RoHS Compliance, REACH Unaffected status, and MSL 4 (72 Hours) moisture sensitivity. The substitute's active product status ensures ongoing availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-004E8 be used as a direct replacement for XRCWHT-L1-0000-002B5?

A: Yes. Both components share identical package dimensions (3529 / 9073 Metric), identical seated height (4.60mm maximum), and identical viewing angle (90°). The forward voltage difference (3.3V vs. 4.6V) is within acceptable tolerance for most circuit designs. Verify your current-limiting circuit accommodates the 0.2V difference if operating near design limits.

Q: What are the key differences between these parts?

A: The substitute operates at 3.3V versus 4.6V, delivers 54 lumens versus 43 lumens at test current, and has superior thermal resistance (8°C/W vs. 12°C/W). The substitute includes a specified color temperature (2700K warm white) and CRI rating (80 Typ), whereas the main part does not specify these parameters. Maximum current rating is higher on the substitute (700mA vs. 500mA).

Q: Are there any compliance or environmental differences?

A: No. Both components are RoHS Compliant, REACH Unaffected, and carry identical MSL 4 (72 Hours) moisture sensitivity ratings. Both use EAR99 ECCN classification.

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

A: The 0.2V reduction (4.6V to 3.3V) decreases power dissipation in series-resistor circuits by approximately 5.7%. For constant-current driver circuits, this difference is transparent. For resistor-based current limiting, recalculate the series resistor value if operating near design limits to maintain target current.

Q: Is the substitute part currently available?

A: Yes. The XREWHT-L1-0000-004E8 has active product status with 1088 pieces in stock as new original inventory, compared to the obsolete XRCWHT-L1-0000-002B5 which is no longer manufactured.
