Key Parameters

Substitute Part Grouping Explanation

Substitute parts for XRCWHT-L1-0000-00903 are qualified based on the following criteria:

Mechanical Compatibility:

• Identical package type: 3529 (9073 Metric)
• Identical physical dimensions: 0.354" L × 0.276" W, 0.181" max height
• Surface mount technology with identical footprint

Electrical Compatibility:

• Identical color and correlated color temperature (CCT): White, Cool, 6000K
• Identical luminous flux at test conditions: 84lm (81lm – 87lm) @ 25°C, 350mA
• Identical test current: 350mA
• Identical viewing angle: 90°
• Identical CRI: 75 (Typ)
• Forward voltage within acceptable operating range for circuit design
• Maximum current rating sufficient for application requirements

Regulatory & Environmental Compliance:

• RoHS Compliant status maintained
• MSL Rating 4 (72 Hours) maintained
• REACH Unaffected status maintained

All four substitute parts meet these criteria. Two variants differ in CCT (5000K vs. 6000K) and packaging configuration (standard vs. R250 reel), allowing selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products from CreeLED, Inc., providing long-term availability and supply chain stability compared to the obsolete XRCWHT-L1-0000-00903.

For 6000K CCT requirement:

• XREWHT-L1-0000-00903 or XREWHT-L1-R250-00903 maintain the original 6000K color temperature specification. Selection between these two depends on packaging requirements: standard Tape & Reel or R250 reel configuration.

For 5000K CCT requirement:

• XREWHT-L1-0000-009E3 or XREWHT-L1-R250-009E3 provide 5000K color temperature. These are suitable where warmer white light is acceptable or specified.

Performance improvements in XLamp® XR-E variants:

• Forward voltage reduced from 4.6V to 3.3V, reducing power dissipation
• Lumens/Watt improved from 69 to 73 lm/W, increasing efficiency
• Thermal resistance improved from 12°C/W to 8°C/W, enhancing thermal performance
• Maximum current rating increased from 500mA to 1A, providing design flexibility

All substitute parts maintain identical luminous flux, CRI, viewing angle, package dimensions, and regulatory compliance status. The XLamp® XR-E series represents a direct performance upgrade with no functional compromises.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00903 be used as a direct replacement for XRCWHT-L1-0000-00903?

A: Yes. Both parts share identical mechanical footprint (3529 package, 9.00mm × 7.00mm), identical luminous flux output (84lm @ 350mA), identical color temperature (6000K), and identical CRI (75). The forward voltage difference (3.3V vs. 4.6V) is within acceptable operating range for most circuit designs. The improved thermal resistance (8°C/W vs. 12°C/W) is a performance benefit.

Q: What is the difference between XREWHT-L1-0000-009E3 and XREWHT-L1-0000-00903?

A: The primary difference is correlated color temperature: XREWHT-L1-0000-009E3 is 5000K (neutral white), while XREWHT-L1-0000-00903 is 6000K (cool white). All other electrical and mechanical parameters are identical. Selection depends on the required color temperature for the application.

Q: What does the "R250" designation in part numbers XREWHT-L1-R250-00903 and XREWHT-L1-R250-009E3 indicate?

A: The R250 designation specifies the reel configuration for tape and reel packaging. Both R250 and standard variants (without R250) are electrically and mechanically identical; the difference is in packaging format for automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (XREWHT-L1-0000-00903, XREWHT-L1-0000-009E3, XREWHT-L1-R250-00903, and XREWHT-L1-R250-009E3) are RoHS Compliant with MSL Rating 4 (72 Hours) and REACH Unaffected status, matching the compliance profile of the original XRCWHT-L1-0000-00903.

Q: Will the lower forward voltage of XLamp® XR-E parts affect circuit design?

A: The forward voltage reduction from 4.6V to 3.3V (0.2V difference) is within typical circuit tolerance. For current-limited designs, this results in slightly lower power dissipation. For voltage-regulated designs, the impact is negligible. Verify compatibility with your specific circuit topology.

Q: What is the inventory status of these substitute parts?

A: XREWHT-L1-0000-00903: 654 pcs; XREWHT-L1-0000-009E3: 1002 pcs; XREWHT-L1-R250-00903: 871 pcs; XREWHT-L1-R250-009E3: 766 pcs. All are listed as new original stock.
