Forward Voltage: 2.85V to 3.05V (compatible with 3V nominal designs)
Test Current: 350mA
Maximum Current: 500mA to 1.5A (accommodates 1A maximum of main part)
Lumens/Watt Efficiency: 118–126 lm/W
CRI: 70 (Typ)

Substitute parts are grouped into two categories:

Category 1: Direct Parametric Equivalents — Parts with identical or near-identical electrical specifications (Vf, flux, efficiency, CRI) and active product status.

Category 2: Functional Equivalents — Parts with compatible electrical performance and active status but minor variations in forward voltage or viewing angle within acceptable design tolerances.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS Compliant)

XPEWHT-01-0000-00FD2, XPEWHT-01-R250-00FD2, and XPEWHT-01-R250-00FC2 are direct parametric equivalents within the XLamp® XP-E series. These parts maintain identical forward voltage (3.05V nominal), flux output (126 lm), CRI (70 Typ), and maximum current (1A) specifications. Both parts carry RoHS Compliant status and active product status, ensuring long-term availability and supply chain continuity.

Secondary Substitutes (Active Status, Enhanced Performance)

XTEAWT-00-0000-00000BFD2 (XLamp® XT-E) and XPGWHT-01-0000-00FC2 (XLamp® XP-G) offer improved thermal performance (5°C/W and 4°C/W respectively, compared to 6°C/W of the main part) and higher maximum current ratings (1.5A). Forward voltage is lower (2.85V and 2.9V), which may reduce power dissipation in constant-current driver applications. These parts are suitable for designs requiring enhanced thermal management or higher current capability.

Tertiary Substitute (Active Status, Identical Electrical Characteristics)

XPCWHT-L1-0000-00FE4 (XLamp® XP-C) matches the main part's forward voltage (3.0V) and efficiency (120 lm/W) but has a lower maximum current rating (500mA). This part is suitable for applications with current-limited designs or where the 1A maximum current of the main part is not required.

CCT Variant (4300K)

XPEWHT-01-0000-00FC3, XPEWHT-01-R250-00FC3, and XPGWHT-01-0000-00FC3 provide 4300K color temperature as an alternative to the 4500K main part. These parts maintain identical flux, efficiency, and electrical characteristics and are suitable for applications requiring slightly warmer neutral white output.

All substitute parts are manufactured by CreeLED, Inc., carry REACH Unaffected and EAR99 ECCN classifications, and are classified under HTSUS 8541.41.0000.

Frequently Asked Questions (FAQ)

Q: Can XPEWHT-01-0000-00FD2 directly replace XPEHEW-01-0000-00FD2 in existing designs?

A: Yes. Both parts share identical forward voltage (3.05V nominal vs. 3.0V), flux output (126 lm), CRI (70 Typ), maximum current (1A), and package dimensions (1414 / 3535 Metric). The XPEWHT-01-0000-00FD2 is active and RoHS Compliant, making it the primary replacement for the obsolete XPEHEW-01-0000-00FD2.

Q: What is the difference between XPEWHT and XPGWHT series?

A: The XLamp® XP-G series (XPGWHT) offers lower forward voltage (2.9V vs. 3.05V), higher efficiency (124 lm/W vs. 118 lm/W), higher maximum current (1.5A vs. 1A), and superior thermal resistance (4°C/W vs. 9°C/W). The XLamp® XP-E series (XPEWHT) provides a more direct electrical match to the main part.

Q: Are there differences in viewing angle between substitute parts?

A: Yes. The main part (XPEHEW-01-0000-00FD2) has a 120° viewing angle. Most XLamp® XP-E substitutes have 115°, while XLamp® XP-G substitutes have 125°. These variations are within acceptable design tolerances for most applications but should be verified for optical designs requiring specific beam characteristics.

Q: What is the significance of the "-R250-" designation in part numbers?

A: The "-R250-" designation indicates packaging in Tape & Reel format with a 250-unit reel quantity. Parts without this designation are supplied in standard Tape & Reel packaging. Electrical and mechanical specifications are identical; the designation reflects packaging and supply format only.

Q: Can I use XTEAWT-00-0000-00000BFD2 as a substitute if my design operates at constant current?

A: Yes. The XTEAWT-00-0000-00000BFD2 (XLamp® XT-E) has lower forward voltage (2.85V) and higher maximum current (1.5A), making it suitable for constant-current driver applications. The lower Vf reduces power dissipation compared to the main part. Verify that your thermal design accommodates the slightly taller package height (0.100" vs. 0.087").

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are REACH Unaffected, classified as EAR99 for export control, and carry HTSUS code 8541.41.0000. XLamp® XT-E, XLamp® XP-E, and XLamp® XP-G series parts are RoHS Compliant. The main part (XPEHEW-01-0000-00FD2) does not specify RoHS status.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory levels vary across substitute parts. XPEWHT-01-R250-00FD2 (1173 Pcs), XPEWHT-01-R250-00FC3 (1136 Pcs), and XPEWHT-01-0000-00FD2 (1121 Pcs) have the highest availability. Verify current stock levels with your supplier before finalizing design changes.
