XPEHEW-01-0000-00DF8 Equivalent & Substitute Parts

Part Overview

The XPEHEW-01-0000-00DF8 is a CreeLED XLamp® XP-E HEW warm white LED (2850K) designed for surface mount applications in the 1414 (3535 Metric) package. This component delivers 111 lumens at 350mA with a forward voltage of 3V and 120° viewing angle. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring warm white LED lighting at this performance level.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XPEHEW-01-0000-00DF8 is determined by the following critical parameters:

Primary Matching Criteria:

• Color and CCT: White, Warm 2850K (exact match required)
• Package / Case: 1414 (3535 Metric) (exact match required)
• Test Current: 350mA (standard operating point)
• CRI: 70 or higher (minimum color rendering requirement)

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 2.77V to 3V range (acceptable for circuit design flexibility)
• Viewing Angle: 115° to 120° (acceptable variation for optical design)
• Lumens/Watt: 106 lm/W or higher (efficiency maintenance)
• Maximum Current Rating: Must support 350mA operation

Mechanical Compatibility:

• Surface Mount mounting type (required)
• Footprint dimensions: 3.45mm x 3.45mm (fixed)
• Height variation: 2.13mm to 2.54mm (acceptable for PCB assembly)

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

XTEAWT-E0-0000-00000BDF8 (XLamp® XT-E)

This substitute is the preferred option for new designs and production transitions. The XT-E series is in active product status, ensuring long-term availability and supply chain stability. It delivers identical luminous flux (111lm) at the same test current (350mA) with improved efficiency (114 lm/W vs. 106 lm/W). The lower forward voltage (2.77V vs. 3V) reduces power dissipation and allows for simpler driver circuit design. The higher maximum current rating (1.5A) provides additional operational headroom. Thermal resistance is superior (5°C/W vs. 6°C/W), improving thermal management. The viewing angle (115°) is within acceptable tolerance for most warm white lighting applications. Tape & Reel packaging supports automated assembly processes. REACH Unaffected and EAR99 classification maintain regulatory compliance.

XPCWHT-L1-0000-00DF8 (XLamp® XP-C)

This substitute provides a direct electrical and optical match with identical forward voltage (3V), viewing angle (120°), and lumens/watt efficiency (106 lm/W). The XP-C series is in active product status with confirmed availability. The lower maximum current rating (500mA vs. 1A) is suitable for applications operating at or below 350mA. Height is reduced (2.13mm vs. 2.21mm), offering improved PCB assembly clearance. Thermal resistance is higher (8°C/W vs. 6°C/W), requiring consideration in high-density thermal environments. Tape & Reel packaging supports standard SMD assembly. REACH Unaffected and EAR99 classification maintain regulatory compliance.

Both substitutes are manufactured by CreeLED, Inc., ensuring consistency in quality standards and technical support. Selection between them depends on circuit design constraints (forward voltage tolerance, maximum current requirements) and thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Why is the XPEHEW-01-0000-00DF8 obsolete, and what does this mean for my application?

A: The XPEHEW-01-0000-00DF8 (XLamp® XP-E HEW) has reached end-of-life status and is no longer manufactured by CreeLED. Existing inventory may be available from authorized distributors, but long-term supply cannot be guaranteed. For new production runs, design transitions, or maintenance applications requiring extended component availability, substitution with an active product is necessary.

Q: Can I use either substitute interchangeably with the original part?

A: Both substitutes are electrically and mechanically compatible at the 350mA test current and 2850K warm white specification. However, they differ in forward voltage, maximum current rating, and thermal characteristics. Circuit design must accommodate the specific forward voltage of the selected substitute. Applications operating above 500mA should use the XTEAWT-E0-0000-00000BDF8 (1.5A maximum). Thermal-sensitive designs should evaluate the thermal resistance differences (5°C/W, 6°C/W, or 8°C/W).

Q: What is the difference in forward voltage between these parts, and does it matter?

A: The XPEHEW and XPCWHT operate at 3V, while the XTEAWT operates at 2.77V. This 0.23V difference affects driver circuit design and power dissipation. Lower forward voltage (XTEAWT) reduces power loss and simplifies constant-current driver requirements. Higher forward voltage (XPEHEW, XPCWHT) may require higher supply voltages in series-connected configurations. Circuit design must account for the selected part's forward voltage specification.

Q: Are all three parts available in the same packaging format?

A: All three parts use the 1414 (3535 Metric) surface mount package with identical footprint dimensions (3.45mm x 3.45mm). The XPEHEW packaging format is not specified in available documentation. Both substitutes are supplied in Tape & Reel (TR) format, supporting automated SMD assembly. Height varies slightly (2.13mm to 2.54mm), which is acceptable for standard PCB assembly processes.

Q: What compliance certifications apply to these parts?

A: All three parts share identical regulatory classifications: REACH Unaffected and ECCN EAR99. HTSUS code 8541.41.0000 applies to all parts. The XTEAWT-E0-0000-00000BDF8 is explicitly RoHS Compliant. RoHS status for the XPEHEW and XPCWHT is not specified in available documentation. Verify RoHS compliance requirements with your supply chain or regulatory team before final part selection.

Q: Which substitute offers the best thermal performance?

A: The XTEAWT-E0-0000-00000BDF8 has the lowest thermal resistance (5°C/W), providing superior heat dissipation compared to the original XPEHEW (6°C/W) and the XPCWHT (8°C/W). In high-density LED arrays or thermally constrained applications, the XT-E series is the preferred choice for thermal management.

Q: Can I mix these parts in the same production batch?

A: Mixing parts with different forward voltages in series-connected LED strings is not recommended without circuit redesign. Parallel configurations require matched current-limiting resistors or individual current sources. For consistent performance and simplified manufacturing, select a single substitute part for standardization across production batches.
