Engineering Selection Recommendations

Direct Equivalent (Identical CCT): XTEAWT-00-0000-00000HDF6 is the primary substitute for XPEHEW-H1-0000-00DF6. Both parts deliver 111 lm at 3750K with 350mA test current and identical 1414 (3535 Metric) package footprint. The XT-E series offers improved thermal resistance (5°C/W vs. 6°C/W), lower forward voltage (2.85V vs. 3V), and higher maximum current rating (1.5A vs. 1A). Product status is Active, ensuring long-term availability.

Parametric Equivalents (Alternative CCT): XPGWHT-H1-0000-00DF6 (3750K) provides exact color temperature matching with identical flux and current specifications. The XP-G series delivers superior thermal performance (4°C/W), higher efficiency (109 lm/W), and RoHS compliance. All XP-G variants maintain 111 lm flux and 350mA test current across CCT options (3000K, 3250K, 3500K, 3750K).

Compliance Considerations: All substitute parts carry REACH Unaffected and EAR99 ECCN classifications matching the original part. XP-G series parts are RoHS Compliant, providing regulatory advantage for new designs. MSL rating remains 1 (Unlimited) across all substitutes.

Thermal and Electrical Advantages: Substitute parts reduce thermal resistance by 20–33%, improving heat dissipation in high-density applications. Forward voltage reduction (2.85–2.9V vs. 3V) decreases power consumption and driver complexity. Higher maximum current ratings (1.5A) provide design margin for transient conditions.

Frequently Asked Questions (FAQ)

Q: Can XTEAWT-00-0000-00000HDF6 replace XPEHEW-H1-0000-00DF6 in existing designs? A: Yes. Both parts deliver identical luminous flux (111 lm) at 3750K color temperature with 350mA test current. The XT-E series operates at lower forward voltage (2.85V vs. 3V) and offers improved thermal resistance (5°C/W vs. 6°C/W). PCB layout and thermal management remain compatible due to identical 1414 (3535 Metric) package footprint.

Q: What is the difference between XP-E HEW, XT-E, and XP-G series? A: All three series maintain identical luminous flux (111 lm) and color temperature (3750K) at 350mA test current. XP-E HEW is obsolete. XT-E and XP-G are active products with improved thermal characteristics. XP-G offers the lowest thermal resistance (4°C/W) and highest efficiency (109 lm/W). XT-E provides a mid-range option with 5°C/W thermal resistance.

Q: Are there color temperature options available? A: Yes. XP-G series substitutes are available in 3000K, 3250K, 3500K, and 3750K. All variants maintain 111 lm flux and 350mA test current. Color temperature selection depends on application requirements; 3750K matches the original part exactly.

Q: What is the impact of lower forward voltage on circuit design? A: Substitute parts operate at 2.85–2.9V versus 3V for the original part. This reduces power dissipation in series resistors and simplifies driver design. No circuit redesign is required; existing current-limiting circuits remain functional with improved efficiency.

Q: Are all substitute parts RoHS compliant? A: XP-G series parts are RoHS Compliant. XTEAWT-00-0000-00000HDF6 (XT-E) and the original XPEHEW-H1-0000-00DF6 do not specify RoHS status. For new designs requiring RoHS compliance, XP-G series is recommended.

Q: What is the viewing angle difference, and does it affect application compatibility? A: Original part: 120°. Substitutes: 115–125°. The variation is within typical application tolerance for general illumination. Designs requiring precise beam control should verify viewing angle specifications against optical requirements.

Q: Can I mix different CCT variants in the same application? A: No. Mixing different color temperatures (3000K, 3250K, 3500K, 3750K) in the same luminaire will produce visible color inconsistency. Select a single CCT variant for all LEDs in an application.

Q: What is the thermal resistance improvement benefit? A: Thermal resistance reduction from 6°C/W (original) to 4–5°C/W (substitutes) improves heat dissipation by 16–33%. This allows higher ambient operating temperatures or reduced thermal management complexity in compact designs.
