Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEWHT-L1-0000-00AF8 is determined by the following critical parameters:

Electrical Compatibility: Forward voltage (3.05V Typ), test current (350mA), and maximum current rating (1A) must remain constant to ensure circuit compatibility without redesign.

Optical Performance: Flux output (91 lm at 25°C, 350mA), lumens per watt (85 lm/W), and CRI (80 Typ) define the lighting performance envelope.

Color Temperature: CCT specification (2850K) establishes the warm white color point and must be maintained for color consistency in lighting applications.

Mechanical Compatibility: Package type (1414/3535 Metric), mounting type (Surface Mount), physical dimensions (0.136" × 0.136" × 0.084" max height), and thermal resistance (9°C/W) ensure PCB layout and thermal management compatibility.

Regulatory Compliance: RoHS Compliant and REACH Unaffected status must be preserved.

Packaging Format: While Tape & Reel (TR) is the primary format, Cut Tape (CT) packaging represents a distribution variation of the same component and does not affect electrical or optical performance.

Parameter Comparison

Engineering Selection Recommendations

The XPEWHT-L1-0000-00AE8 is electrically and mechanically compatible with the XPEWHT-L1-0000-00AF8 for direct substitution in surface mount LED lighting applications. Both parts maintain identical electrical specifications (3.05V forward voltage, 350mA test current, 1A maximum), optical performance (91 lm, 85 lm/W), and mechanical form factor (1414/3535 Metric package, 0.084" max height).

The primary difference is color temperature: the substitute operates at 2700K versus the main part's 2850K. This represents a shift toward warmer color rendering and must be evaluated against application color temperature requirements.

Both parts carry Active product status, RoHS Compliance, and REACH Unaffected certification, ensuring regulatory alignment. The packaging format difference (Cut Tape versus Tape & Reel) reflects distribution method only and does not affect component performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can XPEWHT-L1-0000-00AE8 replace XPEWHT-L1-0000-00AF8 in existing designs?

A: Electrical and mechanical substitution is direct. The 2700K color temperature of the substitute is warmer than the 2850K main part. Applications requiring precise color temperature matching must evaluate this difference against lighting specifications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel is supplied on continuous reel for automated pick-and-place assembly. Cut Tape is supplied in shorter tape segments for manual handling or lower-volume applications. Both contain identical components with no electrical or optical differences.

Q: Are the forward voltage and current ratings identical between these parts?

A: Yes. Both parts operate at 3.05V forward voltage (Typ), 350mA test current, and 1A maximum current. Circuit design parameters remain unchanged.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both XPEWHT-L1-0000-00AF8 and XPEWHT-L1-0000-00AE8 are RoHS Compliant and REACH Unaffected, ensuring equivalent regulatory status.

Q: What is the significance of the 2850K versus 2700K color temperature difference?

A: 2850K produces a slightly warmer (more amber) light compared to 2850K. The difference is approximately 150K on the Kelvin scale. Applications with strict color temperature specifications must account for this variation.

Q: Are the physical dimensions and thermal characteristics the same?

A: Yes. Both parts share identical package dimensions (1414/3535 Metric, 0.136" × 0.136" × 0.084" max height) and thermal resistance (9°C/W), ensuring PCB layout and thermal management compatibility.
