Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPEHEW-L1-0000-00DF4 is determined by the following critical parameters:

Mechanical Compatibility: Package type (1414/3535 Metric), mounting type (Surface Mount), and physical dimensions must remain identical to ensure PCB layout compatibility without redesign.

Optical Performance: Color temperature (4750K), luminous flux (111lm nominal range 107-114lm), and CRI (75 Typ) define the lighting output characteristics. Substitute parts must maintain these specifications within tolerance.

Electrical Characteristics: Test current (350mA), forward voltage (3V nominal), and maximum current rating (1A) establish the operating point and power budget. Substitute parts must operate within these electrical parameters.

Environmental & Compliance: REACH status, MSL rating, and RoHS compliance (where applicable) ensure regulatory and supply chain compatibility.

Substitute parts are grouped into two categories:

1. Direct Parametric Equivalents (XP-G Series): Parts with identical optical output (111lm, 4750K), same test current (350mA), same package (1414), and active product status. These include XPGWHT-L1-0000-00DF4 and variants with different CCT options (4000K, 4250K, 4500K) and packaging configurations (standard and R250 tape).

2. Performance Equivalent (XT-E Series): XTEAWT-00-0000-00000LDF4 offers equivalent optical output (111lm, 4750K) and test current (350mA) in the same package, with improved efficiency (111 lm/W vs 106 lm/W) and lower forward voltage (2.85V vs 3V).

Parameter Comparison

Engineering Selection Recommendations

For Direct 4750K Replacement: XPGWHT-L1-0000-00DF4 is the primary substitute. It maintains identical optical output (111lm at 4750K), test current (350mA), and package (1414), with active product status ensuring long-term availability. The XP-G series offers improved thermal performance (4°C/W vs 6°C/W) and RoHS compliance. Forward voltage is slightly lower (2.9V vs 3V), reducing power dissipation by approximately 4.6% at test current.

For Alternative Color Temperatures: XPGWHT-L1-0000-00DE4 (4500K) and XPGWHT-L1-0000-00DE5 (4000K) provide equivalent luminous flux and electrical characteristics with different CCT options. These are suitable when color temperature adjustment is acceptable within system design parameters.

For Enhanced Efficiency: XTEAWT-00-0000-00000LDF4 delivers the same 111lm output at 4750K with superior efficiency (111 lm/W vs 106 lm/W) and lower forward voltage (2.85V). The XT-E series has higher maximum current rating (1.5A vs 1A) and improved thermal resistance (5°C/W). Viewing angle is slightly narrower (115° vs 120°), which may affect optical system design.

Packaging Considerations: XP-G variants with R250 designation (XPGWHT-L1-R250-00DF4, XPGWHT-L1-R250-00DE4, etc.) are supplied in Tape & Reel format, identical to standard versions in electrical and optical performance. Selection depends on procurement and assembly requirements.

Compliance: All substitute parts maintain REACH Unaffected status. XP-G and XT-E series are RoHS Compliant, providing regulatory advantage over the obsolete XP-E HEW part.

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-L1-0000-00DF4 be used as a direct drop-in replacement for XPEHEW-L1-0000-00DF4?

A: Yes. Both parts share identical package (1414), mounting type (Surface Mount), optical output (111lm at 4750K), test current (350mA), and CRI (75). The 0.1V lower forward voltage (2.9V vs 3V) reduces power consumption without affecting circuit compatibility. PCB layout requires no modification.

Q: What is the impact of the lower forward voltage in XP-G and XT-E substitutes?

A: Lower forward voltage reduces power dissipation at the same test current. For a 350mA circuit, XP-G parts consume approximately 4.6% less power than the original XP-E HEW. This improves thermal performance and extends LED lifetime. Current-limiting circuits will operate identically; no design changes are required.

Q: Are there viewing angle differences between substitutes?

A: Yes. The original XPEHEW-L1-0000-00DF4 has a 120° viewing angle. XPGWHT-L1-0000-00DF4 (XP-G) offers 125°, and XTEAWT-00-0000-00000LDF4 (XT-E) offers 115°. These differences affect light distribution patterns. For applications requiring specific beam geometry, optical system design may require adjustment.

Q: What is the difference between standard and R250 tape packaging?

A: R250 designation indicates 250mm reel diameter for automated assembly. Electrical, optical, and thermal specifications are identical between standard and R250 variants. Selection depends on pick-and-place equipment compatibility and procurement preferences.

Q: Why is the original XPEHEW-L1-0000-00DF4 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured. CreeLED has transitioned to the XP-G and XT-E series, which offer improved efficiency, thermal performance, and RoHS compliance. Substitutes ensure design continuity and long-term supply security.

Q: Can I use XPGWHT-L1-0000-00DE5 (4000K) instead of the 4750K original?

A: Substitution is possible if color temperature adjustment is acceptable. Both parts deliver identical luminous flux (111lm) and electrical characteristics (350mA test current, 2.9V Vf). The 750K color temperature difference shifts the light output toward warmer tones. System performance remains unchanged; only perceived color changes.

Q: What thermal advantages do XP-G substitutes offer?

A: XP-G parts have thermal resistance of 4°C/W compared to 6°C/W for the original XP-E HEW. This 33% improvement reduces junction temperature rise by approximately 0.7°C per watt of dissipated power, extending LED lifetime and improving reliability in thermally constrained applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. XPGWHT series (XP-G) and XTEAWT series (XT-E) are RoHS Compliant. The original XPEHEW-L1-0000-00DF4 does not specify RoHS status. Substitutes provide regulatory compliance advantage for new designs and updated production.
