XPEHEW-01-0000-00DF7 Equivalent & Substitute Parts

Part Overview

The XPEHEW-01-0000-00DF7 is a CreeLED XLamp® XP-E HEW warm white LED (3250K) designed for surface mount applications in the 1414 (3535 Metric) package. This part operates at 3V forward voltage with 350mA test current, delivering 111 lumens at 25°C and 106 lumens per watt efficiency. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring warm white LED lighting at this color temperature and performance level.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XPEHEW-01-0000-00DF7 is determined by the following critical parameters:

Primary Substitution Criteria:

• Color and CCT: White, Warm 3250K (exact match required)
• Package / Case: 1414 (3535 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Test Current: 350mA (exact match required)
• CRI: 70 or higher (minimum acceptable)

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 2.85V to 3V range (acceptable for circuit design flexibility)
• Viewing Angle: 115° to 120° (acceptable for optical design compatibility)
• Maximum Current: 500mA or higher (acceptable; higher ratings provide design margin)
• Thermal Resistance: 5°C/W to 8°C/W (acceptable; lower values indicate improved thermal performance)

Two substitute parts meet these criteria and are identified below.

Parameter Comparison

Engineering Selection Recommendations

XPCWHT-L1-0000-00DF7 (XLamp® XP-C): This part is an active product with identical electrical performance to the obsolete XPEHEW-01-0000-00DF7. Forward voltage, test current, flux output, and CRI are equivalent. The maximum current rating is reduced to 500mA, which may limit design flexibility in high-current applications. Height is slightly lower (2.13mm vs. 2.21mm), and thermal resistance is higher (8°C/W vs. 6°C/W). This substitute is suitable for applications where the 500mA maximum current limit is acceptable and thermal management is not critical.

XTEAWT-00-0000-00000BDF7 (XLamp® XT-E): This part is an active product with superior thermal performance (5°C/W vs. 6°C/W) and higher efficiency (111 lm/W vs. 106 lm/W). Forward voltage is slightly lower at 2.85V, which may require minor circuit adjustments but remains within acceptable design tolerance. Maximum current rating is 1.5A, providing greater design margin. Height is slightly higher (2.54mm vs. 2.21mm). This substitute offers improved thermal and electrical performance characteristics. Packaging is specified as Tape & Reel (TR), whereas the main part packaging is not specified.

Both substitutes are active products from CreeLED, Inc., ensuring ongoing availability and support. Selection between them depends on thermal management requirements, maximum current headroom, and packaging format needs.

Frequently Asked Questions (FAQ)

Q: Can XPCWHT-L1-0000-00DF7 and XTEAWT-00-0000-00000BDF7 be used interchangeably with XPEHEW-01-0000-00DF7?

A: Both parts meet the primary substitution criteria: identical color temperature (3250K), package (1414/3535 Metric), test current (350mA), and flux output (111lm). However, they differ in forward voltage, maximum current, and thermal characteristics. Circuit design must accommodate these differences. Forward voltage differences (3V vs. 2.85V) may require minor adjustments to current-limiting resistor values. Maximum current ratings differ, affecting design headroom.

Q: What is the impact of forward voltage differences?

A: The XTEAWT-00-0000-00000BDF7 operates at 2.85V versus 3V for the main part and XPCWHT-L1-0000-00DF7. In a constant-current driver circuit, this difference is transparent. In resistor-based current limiting circuits, the lower forward voltage of the XT-E will result in slightly higher current through the limiting resistor. Recalculation of resistor values is required to maintain 350mA test current.

Q: Are there packaging format differences?

A: The XTEAWT-00-0000-00000BDF7 is specified as Tape & Reel (TR) packaging. The main part and XPCWHT-L1-0000-00DF7 do not have packaging format specified. Tape & Reel format is standard for high-volume surface mount assembly and is compatible with automated pick-and-place equipment.

Q: Which substitute offers better thermal performance?

A: The XTEAWT-00-0000-00000BDF7 has the lowest thermal resistance at 5°C/W, compared to 6°C/W for the main part and 8°C/W for the XPCWHT-L1-0000-00DF7. Lower thermal resistance indicates more efficient heat dissipation from the LED junction to the PCB. This is advantageous in applications with sustained high-current operation or limited thermal management.

Q: What is the significance of maximum current ratings?

A: The XPEHEW-01-0000-00DF7 and XTEAWT-00-0000-00000BDF7 support 1A and 1.5A maximum current respectively, while XPCWHT-L1-0000-00DF7 is limited to 500mA. These ratings define the absolute maximum current the LED can safely handle. Applications requiring operation above 500mA must use either the main part or the XT-E substitute.

Q: Are all three parts RoHS and REACH compliant?

A: The XTEAWT-00-0000-00000BDF7 is specified as RoHS Compliant. All three parts are REACH Unaffected. The main part XPEHEW-01-0000-00DF7 does not specify RoHS status. Compliance documentation should be verified with the manufacturer for the specific application requirements.

Q: Can height differences affect PCB layout?

A: The three parts have different maximum seated heights: XPEHEW-01-0000-00DF7 at 0.087" (2.21mm), XPCWHT-L1-0000-00DF7 at 0.084" (2.13mm), and XTEAWT-00-0000-00000BDF7 at 0.100" (2.54mm). The XT-E is 0.013" taller than the main part. In applications with tight vertical clearance constraints, this difference may require PCB layout verification.
