Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEHEW-01-0000-00CF8 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must be White, Warm 2850K to maintain identical color output
• Package / Case: Both parts must use 1414 (3535 Metric) surface mount package for mechanical and thermal compatibility
• Mounting Type: Surface mount requirement must be maintained
• Electrical Compatibility: Forward voltage, test current, and maximum current ratings must be within acceptable operating ranges for the application circuit
• Optical Performance: Flux output and lumens/watt efficiency should be comparable to support equivalent brightness levels
• CRI (Color Rendering Index): Color rendering characteristics must match or exceed the original specification
• Thermal Characteristics: Thermal resistance must be suitable for the thermal management design

The XTEAWT-00-0000-00000BCF8 qualifies as a substitute based on matching color temperature, package format, mounting type, and comparable electrical and optical performance within the defined parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The XTEAWT-00-0000-00000BCF8 is the designated substitute for the obsolete XPEHEW-01-0000-00CF8 based on the following factors:

Product Status: The XTEAWT-00-0000-00000BCF8 carries Active product status, ensuring ongoing availability and manufacturer support, whereas the original part is Obsolete.

Compliance and Certifications: The substitute part is RoHS Compliant, providing enhanced environmental and regulatory compliance compared to the main part specification. Both parts maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Electrical Compatibility: The substitute operates at a slightly lower forward voltage (2.85V vs. 3V) with identical test current (350mA) and higher maximum current rating (1.5A vs. 1A). This provides improved efficiency and operational headroom in circuit designs.

Optical Performance: Both parts deliver identical flux output (104 lm) at their respective test conditions and maintain matching CRI (70), ensuring equivalent color rendering and brightness characteristics.

Thermal Characteristics: The substitute exhibits superior thermal resistance (5°C/W vs. 6°C/W), supporting better thermal management in high-power applications.

Mechanical Compatibility: Both parts use identical 1414 (3535 Metric) packages with matching footprints. The substitute height (2.54mm) is marginally taller than the original (2.21mm) but remains within typical PCB assembly tolerances for surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the XTEAWT-00-0000-00000BCF8 be used as a direct replacement for the XPEHEW-01-0000-00CF8?

A: Yes. Both parts share identical color temperature (2850K), package format (1414 / 3535 Metric), mounting type (surface mount), and comparable optical performance (104 lm flux, 70 CRI). The forward voltage difference (2.85V vs. 3V) is within typical circuit design tolerances and may require minor current-limiting resistor adjustment depending on the application circuit.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Series designation (XP-E HEW vs. XT-E), (2) Forward voltage (3V vs. 2.85V), (3) Maximum current rating (1A vs. 1.5A), (4) Thermal resistance (6°C/W vs. 5°C/W), (5) Height (2.21mm vs. 2.54mm), (6) Product status (Obsolete vs. Active), and (7) RoHS compliance (not specified vs. compliant).

Q: Will the height difference (2.21mm vs. 2.54mm) affect PCB assembly?

A: The 0.33mm height difference is within standard surface mount assembly tolerances. PCB design and reflow profile parameters may require minor adjustment, but mechanical compatibility with 1414 (3535 Metric) footprints is maintained.

Q: Does the lower forward voltage of the substitute affect circuit design?

A: The 0.15V difference may require adjustment of current-limiting resistor values to maintain the same test current (350mA) in the application circuit. Circuit designers should recalculate resistor values based on the substitute's forward voltage specification.

Q: Are both parts available in the same packaging format?

A: The main part packaging is not specified. The substitute is available in Tape & Reel (TR) format, which is standard for high-volume surface mount production.

Q: What is the significance of the RoHS Compliant status of the substitute?

A: RoHS Compliance indicates the substitute meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This provides enhanced environmental compliance for applications subject to RoHS requirements.
