Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete XPEHEW-01-0000-00CE7 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color temperature: 3000K (warm white)
• Package format: 1414 (3535 Metric) surface mount
• Test current: 350mA nominal operation
• Flux output range: 100–107 lm @ 25°C
• Forward voltage tolerance: 2.9V–3.0V typical
• Viewing angle: 115°–120°
• Thermal resistance: 5–6°C/W
• Mounting type: Surface mount

The substitute part XTEAWT-02-0000-00000LCZ7 meets these criteria within acceptable engineering tolerances for direct replacement in existing PCB layouts and driver circuits.

Parameter Comparison

Engineering Selection Recommendations

The XTEAWT-02-0000-00000LCZ7 is the designated substitute for the obsolete XPEHEW-01-0000-00CE7 based on the following factors:

Product Status: The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance & Certifications: The substitute part carries RoHS Compliant certification, providing enhanced environmental compliance. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical Compatibility: Both parts operate at 350mA test current with identical flux output (104 lm, 100–107 lm range) and matching 3000K color temperature. The forward voltage difference of 0.1V (3V vs. 2.9V) is within typical driver circuit tolerance margins for constant-current LED applications.

Mechanical Fit: Both components use identical 1414 (3535 Metric) package format and footprint dimensions (3.45mm × 3.45mm). The height difference of 0.013" (0.33mm) is negligible for standard PCB assembly and does not affect reflow soldering or component placement.

Thermal Performance: The substitute part offers improved thermal resistance (5°C/W vs. 6°C/W), resulting in lower junction temperatures under identical operating conditions.

Optical Performance: The substitute part delivers superior CRI (75 vs. 70) and efficiency (102 lm/W vs. 99 lm/W), with a 5° reduction in viewing angle (115° vs. 120°) that remains suitable for most general illumination applications.

Frequently Asked Questions (FAQ)

Q: Can the XTEAWT-02-0000-00000LCZ7 be used as a direct replacement for the XPEHEW-01-0000-00CE7 without circuit modifications?

A: Yes. Both parts operate at 350mA test current with identical flux output and color temperature. The 0.1V forward voltage difference is accommodated by standard constant-current LED driver circuits. PCB footprints are identical (1414 / 3535 Metric), requiring no layout changes.

Q: What is the significance of the height difference between the two parts?

A: The main part has a seated height of 0.087" (2.21mm), while the substitute has 0.100" (2.54mm). This 0.013" (0.33mm) difference does not affect reflow soldering, component placement accuracy, or clearance in standard PCB assemblies.

Q: Does the substitute part's improved CRI (75 vs. 70) affect compatibility?

A: No. Higher CRI is a performance enhancement that improves color rendering quality. This change is backward-compatible and does not introduce any electrical or mechanical incompatibilities.

Q: Why does the substitute part have a higher maximum current rating (1.5A vs. 1A)?

A: The XTEAWT-02-0000-00000LCZ7 is designed with enhanced current handling capability. At the standard 350mA test current, both parts operate identically. The higher maximum rating provides additional design margin and flexibility for future applications.

Q: Is the RoHS Compliant status of the substitute part important?

A: Yes. The substitute part's RoHS Compliant certification ensures compliance with environmental regulations in markets requiring RoHS adherence. The main part's RoHS status was not specified, making the substitute the preferred choice for regulated applications.

Q: Are there any packaging or supply chain differences between the two parts?

A: The main part is supplied in standard packaging with 819 units in stock. The substitute part is supplied in Tape & Reel (TR) format with 746 units in stock, which is the standard format for high-volume automated assembly operations.
