Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEHEW-H1-0000-00AF8 is determined by the following critical parameters:

• Color and CCT: Warm white 2850K or 2700K (acceptable variance for warm white applications)
• Flux output: 91 lm nominal at 350mA test current (87–94 lm range)
• Forward voltage: 2.85V to 3V range
• Test current: 350mA
• CRI: 80 (Color Rendering Index)
• Package: 1414 (3535 Metric) surface mount
• Mounting type: Surface mount
• Physical dimensions: 3.45mm × 3.45mm footprint

Substitute parts are grouped into two categories:

1. Direct Series Equivalent (XLamp® XT-E): XTEAWT-00-0000-00000HAF8 — Same CCT (2850K), same flux output, same test current, same package, with lower forward voltage (2.85V) and higher maximum current rating (1.5A).

2. Parametric Equivalents (XLamp® XP-G): XPGWHT series parts — Active product line with identical flux output, test current, and package. Available in both 2700K and 2850K CCT variants. Forward voltage 2.9V, higher maximum current (1.5A), and improved thermal resistance (4°C/W vs. 6°C/W).

Parameter Comparison

Engineering Selection Recommendations

For 2850K CCT Requirement:

XPGWHT-H1-0000-00AF8 and XPGWHT-H1-R250-00AF8 are the primary active substitutes. Both are RoHS compliant, active products with identical flux output (91 lm), test current (350mA), and package specifications. The difference between these two is packaging format (standard vs. R250 reel). Forward voltage is 2.9V (0.1V lower than the main part), which is within acceptable tolerance for most circuit designs. Thermal resistance is improved (4°C/W vs. 6°C/W), providing better heat dissipation. Maximum current rating is increased to 1.5A, offering greater design margin.

For 2700K CCT Requirement:

XPGWHT-H1-0000-00AE8 and XPGWHT-H1-R250-00AE8 provide equivalent performance with 2700K color temperature. These parts are suitable where slightly warmer color temperature is acceptable. All electrical and thermal characteristics match the 2850K variants.

Alternative with Lower Forward Voltage:

XTEAWT-00-0000-00000HAF8 (XLamp® XT-E series) maintains 2850K CCT and 91 lm output at 350mA. Forward voltage is 2.85V, providing the lowest voltage drop among substitutes. Thermal resistance is 5°C/W. This part is active and RoHS compliant, available in Tape & Reel packaging.

Design Considerations:

All substitute parts maintain identical flux output, test current, and CRI specifications. Viewing angle varies slightly (115° to 125° vs. 120°), which is negligible for most applications. Height differences are minimal (0.084" to 0.100" vs. 0.087"), with no impact on PCB assembly. Forward voltage reduction (2.85V to 2.9V vs. 3V) requires circuit verification to ensure proper current limiting and power supply compatibility.

Frequently Asked Questions (FAQ)

Q: Can I directly replace XPEHEW-H1-0000-00AF8 with XPGWHT-H1-0000-00AF8?

A: Yes. Both parts deliver 91 lumens at 350mA test current, maintain 80 CRI, and use the 1414 (3535 Metric) package. The primary difference is forward voltage (2.9V vs. 3V). Verify your current-limiting circuit accommodates the lower voltage drop. The XP-G series offers improved thermal resistance (4°C/W vs. 6°C/W) and higher maximum current rating (1.5A vs. 1A).

Q: What is the difference between XPGWHT-H1-0000-00AF8 and XPGWHT-H1-R250-00AF8?

A: These parts are electrically and optically identical. The difference is packaging format: standard reel vs. R250 reel configuration. Select based on your assembly equipment compatibility and supply chain requirements.

Q: Can I use a 2700K part (XPGWHT-H1-0000-00AE8) instead of the 2850K original?

A: Yes, if your application permits a slight color temperature shift. Both maintain 91 lm output, 80 CRI, and identical electrical characteristics. The 2700K variant produces a slightly warmer appearance. Verify color matching requirements for your end application.

Q: Why is the forward voltage lower on substitute parts?

A: The XLamp® XT-E and XP-G series represent newer LED technology generations with improved efficiency. Lower forward voltage (2.85V to 2.9V) reduces power dissipation while maintaining the same light output. Ensure your current-limiting resistor or driver circuit is recalculated for the new voltage to maintain 350mA test current.

Q: Are all substitute parts RoHS compliant?

A: Yes. All XLamp® XP-G and XT-E substitute parts are RoHS compliant. The original XPEHEW-H1-0000-00AF8 RoHS status is not specified in the data provided.

Q: What is the impact of thermal resistance differences?

A: Substitute parts offer equal or better thermal resistance (4°C/W to 5°C/W vs. 6°C/W). Lower thermal resistance improves heat dissipation from the LED junction, resulting in cooler operation and potentially extended lifespan under identical thermal conditions.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts maintain identical flux output (91 lm), test current (350mA), and CRI (80), making them interchangeable from an optical standpoint. However, forward voltage differences (2.85V to 3V) require consistent current-limiting circuit design. Use parts with the same forward voltage specification within a single design to simplify circuit implementation.

Q: What is the viewing angle impact?

A: The original part has 120° viewing angle. Substitutes range from 115° to 125°. This variation is negligible for most applications. Verify specific beam distribution requirements for your optical design.
