Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEHEW-01-0000-00CF7 is determined by the following critical parameters:

• Color Temperature (CCT): 3250K warm white specification
• Package / Case: 1414 (3535 Metric) surface mount form factor
• Flux Output: Nominal 104 lm at 350mA test current
• Forward Voltage: Operating range compatible with 3V nominal design
• CRI: 70 or higher for color rendering consistency
• Viewing Angle: 120° or greater for optical compatibility
• Thermal Resistance: 6°C/W or lower for thermal management equivalence

The XTEAWT-00-0000-00000BCF7 (XLamp® XT-E series) qualifies as a direct substitute based on matching color temperature, package form factor, flux output range, CRI specification, and thermal performance within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The XTEAWT-00-0000-00000BCF7 is the qualified substitute for the obsolete XPEHEW-01-0000-00CF7 based on the following engineering criteria:

Product Status: The substitute part is Active, ensuring ongoing availability and manufacturing support, whereas the main part is Obsolete.

Compliance & Certifications: Both parts maintain REACH Unaffected status and EAR99 export classification, ensuring regulatory continuity. The substitute carries RoHS Compliant certification, providing additional environmental compliance assurance.

Optical & Thermal Performance: The substitute delivers equivalent flux output (104 lm) at identical test current (350mA) with improved thermal resistance (5°C/W vs. 6°C/W), supporting enhanced thermal management in production designs.

Electrical Compatibility: Forward voltage differs by 0.15V (2.85V vs. 3V), which is within typical design tolerance for constant-current LED driver circuits. Maximum current rating is higher (1.5A vs. 1A), providing additional operational margin.

Mechanical Fit: Both parts use identical 1414 (3535 Metric) packages with matching lateral dimensions (3.45mm x 3.45mm). Height difference (2.54mm vs. 2.21mm) is 0.33mm, which must be evaluated against specific PCB assembly and enclosure constraints.

Optical Characteristics: Viewing angle is 115° (substitute) versus 120° (main part), a 5° reduction that may affect light distribution in wide-angle applications. CRI remains constant at 70.

Frequently Asked Questions (FAQ)

Q: Can the XTEAWT-00-0000-00000BCF7 directly replace the XPEHEW-01-0000-00CF7 in existing designs?

A: Yes, for most applications. Both parts share identical color temperature (3250K), package form factor (1414/3535 Metric), and flux output (104 lm at 350mA). The 0.15V forward voltage difference is manageable in constant-current driver circuits. Verify that the 0.33mm height increase and 5° viewing angle reduction do not conflict with your specific mechanical or optical requirements.

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

A: In constant-current LED driver designs, this 0.15V difference has minimal impact on circuit operation. If your design uses a fixed voltage supply with series resistor, recalculate the resistor value to maintain 350mA test current. The substitute's lower forward voltage will reduce power dissipation in the resistor.

Q: Are there any thermal management differences?

A: The substitute has superior thermal resistance (5°C/W vs. 6°C/W), meaning it dissipates heat more efficiently. This is advantageous for thermal-constrained applications and does not present any compatibility issues.

Q: Does the viewing angle reduction from 120° to 115° affect compatibility?

A: The 5° reduction is minor and suitable for most general illumination applications. If your design requires the full 120° beam spread for specific optical performance, evaluate the impact on light distribution in your application. For most standard lighting designs, 115° is functionally equivalent.

Q: What is the height difference impact on PCB assembly?

A: The substitute is 0.33mm taller (2.54mm vs. 2.21mm). Verify that this height increase does not conflict with enclosure clearances, lens positioning, or thermal interface requirements in your specific assembly.

Q: Is the substitute part readily available?

A: Yes. The XTEAWT-00-0000-00000BCF7 is Active status with 1032 pcs in stock, ensuring production availability. The main part (XPEHEW-01-0000-00CF7) is Obsolete with limited remaining inventory (1132 pcs).

Q: Are compliance certifications equivalent?

A: Both parts maintain REACH Unaffected and EAR99 classifications. The substitute adds RoHS Compliant certification, providing enhanced environmental compliance documentation for regulated markets.
