Engineering Selection Recommendations

All substitute parts listed maintain functional compatibility with XPEHEW-01-0000-00EE4 through matching flux output, color temperature range, CRI, test current, and 1414 package specifications.

For RoHS-compliant applications, select from the XLamp® XP-E series (XPEWHT variants) or XLamp® XP-G series (XPGWHT variants). All XP-E and XP-G parts carry RoHS Compliant status and active product designation, ensuring long-term supply chain stability and regulatory compliance.

For applications requiring superior thermal performance, the XLamp® XP-G series (4°C/W thermal resistance) and XT-E series (5°C/W thermal resistance) offer improved heat dissipation compared to the original part (6°C/W). These series also support higher maximum current (1.5A vs. 1A), providing design margin for future upgrades.

For color temperature flexibility, XP-E and XP-G series are available in 4300K, 4500K, and 4100K variants, allowing precise color matching to application requirements.

For packaging options, XP-E parts are available in both standard and Tape & Reel (TR) configurations. XP-G parts are supplied in Tape & Reel format. XT-E is supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can XPEWHT-01-0000-00EC2 directly replace XPEHEW-01-0000-00EE4?

A: Yes. Both parts maintain identical flux output (118lm), CRI (70), test current (350mA), and 1414 package specifications. Forward voltage differs by 0.05V (3.05V vs. 3V), which is within acceptable tolerance for most circuit designs. XPEWHT-01-0000-00EC2 is RoHS compliant and carries active product status.

Q: What is the difference between XP-E and XP-G series substitutes?

A: XP-G series offers superior thermal performance (4°C/W vs. 9°C/W for XP-E) and higher maximum current rating (1.5A vs. 1A). Both maintain identical flux output and CRI. XP-G series has a slightly wider viewing angle (125° vs. 115°). Forward voltage is 2.9V for XP-G versus 3.05V for XP-E.

Q: Are all substitute parts RoHS compliant?

A: XLamp® XP-E and XP-G series parts are RoHS Compliant. The XT-E series part does not specify RoHS status in the provided data. For applications requiring RoHS compliance, select from XP-E or XP-G series.

Q: What does the "R250" designation in part numbers indicate?

A: The R250 designation indicates Tape & Reel packaging with 250-unit reels. Parts without this designation are supplied in standard packaging. Both formats maintain identical electrical and mechanical specifications.

Q: Can I use XPGWHT-01-0000-00EC3 (4300K) instead of XPEHEW-01-0000-00EE4 (4500K)?

A: Yes, if your application tolerates a 200K color temperature shift. Both parts maintain identical flux output (118lm), CRI (70), test current (350mA), and 1414 package specifications. The 4300K variant provides slightly warmer color rendering. Verify color matching requirements for your specific application.

Q: What is the thermal resistance difference, and does it matter?

A: The original part has 6°C/W thermal resistance. XP-E substitutes have 9°C/W, while XP-G and XT-E substitutes have 4°C/W and 5°C/W respectively. Lower thermal resistance improves heat dissipation. For applications with thermal constraints or high ambient temperatures, XP-G or XT-E series are preferred. For standard applications, XP-E series is functionally equivalent.

Q: Are there inventory considerations for substitute selection?

A: Current inventory levels are provided for reference. XP-E series parts (XPEWHT variants) range from 696–987 units. XP-G series parts (XPGWHT variants) range from 714–966 units. XT-E series has 955 units available. Consult with your supplier for long-term availability and lead time requirements.
