Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XPEHEW-01-0000-00CE8 is determined by the following critical parameters:

• Color and CCT Match: Warm white 2700K specification
• Package Compatibility: 1414 (3535 Metric) surface mount package
• Electrical Performance: Test current of 350 mA with flux output in the 100–107 lm range
• Forward Voltage Tolerance: Nominal 3V operation (minor variations acceptable within circuit design margins)
• CRI Specification: Color rendering index of 70 or higher
• Viewing Angle: 120° or greater
• Thermal Characteristics: Thermal resistance ≤ 6°C/W

The substitute part XTEAWT-00-0000-00000BCE8 meets all critical substitution criteria, with minor variations in forward voltage (2.85V vs. 3V), viewing angle (115° vs. 120°), and thermal resistance (5°C/W vs. 6°C/W). These variations remain within acceptable engineering tolerances for equivalent functionality.

Parameter Comparison

Engineering Selection Recommendations

The XTEAWT-00-0000-00000BCE8 is the qualified substitute for the obsolete XPEHEW-01-0000-00CE8. Selection is supported by the following factors:

• Product Status: The substitute is active and currently available, addressing the obsolescence of the main part.
• Regulatory Compliance: The substitute carries RoHS Compliant certification, meeting modern environmental and safety standards.
• Electrical Equivalence: Both parts operate at 350 mA test current with identical flux output (104 lm) and matching 2700K color temperature and CRI specifications.
• Package Compatibility: Identical 1414 (3535 Metric) surface mount package ensures PCB layout compatibility without redesign.
• Performance Improvement: The substitute offers lower forward voltage (2.85V vs. 3V), improved efficiency (104 lm/W vs. 99 lm/W), and superior thermal characteristics (5°C/W vs. 6°C/W).

Minor dimensional variation in seated height (2.54 mm vs. 2.21 mm) must be evaluated within specific assembly and optical design constraints.

Frequently Asked Questions (FAQ)

Q: Can the XTEAWT-00-0000-00000BCE8 be used as a direct replacement for the XPEHEW-01-0000-00CE8?

A: Yes. Both parts share identical color temperature (2700K), flux output (104 lm at 350 mA), CRI (70), and package format (1414 / 3535 Metric). The substitute is electrically and mechanically compatible for equivalent functionality.

Q: What is the significance of the forward voltage difference (3V vs. 2.85V)?

A: The 0.15V difference is within typical circuit design margins. Existing driver circuits designed for 3V operation will function with the 2.85V substitute. The lower voltage may reduce power dissipation slightly, improving overall system efficiency.

Q: Does the viewing angle difference (120° vs. 115°) affect compatibility?

A: The 5° reduction in viewing angle is minor and remains within acceptable tolerances for most warm white LED applications. Optical design review is recommended only if the application requires the full 120° specification.

Q: Why is the seated height different (2.21 mm vs. 2.54 mm)?

A: The 0.33 mm height increase reflects design differences between the XP-E HEW and XT-E series. PCB clearance and optical assembly constraints must be verified during integration.

Q: Is the substitute RoHS compliant?

A: Yes. The XTEAWT-00-0000-00000BCE8 carries RoHS Compliant certification, meeting current environmental regulations. The main part status is not specified.

Q: Can I use the substitute at higher currents (up to 1.5A)?

A: The substitute supports a maximum current of 1.5A versus 1A for the main part. However, operation at the original 350 mA test current maintains flux and thermal specifications. Higher current operation requires thermal and optical performance validation.
