Substitute Part Grouping Explanation

Substitution of the XPEHEW-01-0000-00GE4 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Color temperature: 4500K (or adjacent CCT values within 4300K–4500K range)
Flux output: 135 lm at 350mA test current (130–139 lm acceptable range)
Test current: 350mA
Package: 1414 (3535 Metric)
Mounting type: Surface Mount
CRI: 70 (Typ)
Viewing angle: 120° or greater

Electrical Compatibility Parameters:

Forward voltage: 3V or lower (to maintain circuit compatibility)
Maximum current rating: ≥350mA minimum

Thermal Compatibility:

Thermal resistance: ≤6°C/W preferred for equivalent thermal performance

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Active Status) Parts from active XLamp® product lines (XP-C, XP-G, XT-E) that match all mandatory parameters and maintain electrical compatibility. These parts are recommended for new designs and ongoing production.

Category 2: Secondary Equivalents Parts with minor parameter variations (CCT ±200K, viewing angle ±5°, thermal resistance variation) that function within acceptable design tolerances but require circuit verification.

Engineering Selection Recommendations

Primary Recommendation: XPGWHT-01-0000-00GE4 (XLamp® XP-G)

The XPGWHT-01-0000-00GE4 is the preferred direct substitute. It maintains identical flux output (135 lm), color temperature (4500K), CRI (70), viewing angle (125° vs. 120°), and package format (1414/3535 Metric). Forward voltage is 2.9V versus 3.0V, reducing power dissipation by approximately 3.3% at 350mA. Thermal resistance improves to 4°C/W. Product status is Active with RoHS compliance, ensuring long-term availability and regulatory alignment.

Secondary Recommendation: XTEAWT-00-0000-00000BGE4 (XLamp® XT-E)

The XTEAWT-00-0000-00000BGE4 offers improved thermal performance (5°C/W) and higher maximum current rating (1.5A). Forward voltage is 2.85V, providing additional power efficiency. Viewing angle is 115° versus 120°, a 4.2% reduction that may affect beam distribution in wide-angle applications. Product status is Active with RoHS compliance.

Alternative for CCT Flexibility: XPGWHT-01-0000-00GC3 or XPGWHT-01-0000-00GD3 (XLamp® XP-G, 4300K)

These parts provide identical electrical and thermal performance to XPGWHT-01-0000-00GE4 with CCT at 4300K instead of 4500K. Selection depends on application color temperature tolerance. Both are Active status with RoHS compliance.

Not Recommended: XPCWHT-L1-0000-00GE4 (XLamp® XP-C)

While this part matches forward voltage (3.0V) and viewing angle (120°), its maximum current rating is limited to 0.5A, restricting design flexibility. Thermal resistance is higher at 8°C/W. Use only if circuit design constrains current to ≤500mA.

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-01-0000-00GE4 directly replace XPEHEW-01-0000-00GE4 without circuit modification?

A: Yes. Both parts operate at 350mA test current with identical flux output (135 lm) and color temperature (4500K). The forward voltage difference (2.9V vs. 3.0V) is within typical circuit tolerance. Verify that the power supply can accommodate the lower voltage drop. No PCB layout changes are required; both use the same 1414 (3535 Metric) package.

Q: What is the impact of the 5°C/W thermal resistance difference between XPEHEW-01-0000-00GE4 (6°C/W) and XPGWHT-01-0000-00GE4 (4°C/W)?

A: Lower thermal resistance improves heat dissipation. At 350mA, the junction temperature rise will be approximately 0.7°C lower with XPGWHT-01-0000-00GE4, enhancing reliability and light output stability over the operating temperature range.

Q: Are there CCT alternatives if 4500K is not available?

A: Yes. XPGWHT-01-0000-00GC3 and XPGWHT-01-0000-00GD3 provide 4300K, while XPGWHT-01-0000-00GE5 provides 4000K. All maintain identical flux, current, and package specifications. XPGWHT-01-0000-00GF5 offers 4250K as an intermediate option.

Q: What is the difference between XPGWHT-01-0000-00GE4 and XPGWHT-01-R250-00GC2?

A: Both are XLamp® XP-G parts with identical electrical and optical specifications. The "R250" designation indicates a 250-unit reel packaging variant. Electrical performance and thermal characteristics are identical; selection depends on procurement quantity requirements.

Q: Is RoHS compliance required for my application?

A: The original XPEHEW-01-0000-00GE4 does not list RoHS status. All recommended XLamp® XP-G and XT-E substitutes are RoHS Compliant, meeting EU Directive 2011/65/EU requirements. If RoHS compliance is mandatory, select from the XP-G or XT-E series.

Q: Can XTEAWT-00-0000-00000BGE4 be used if the circuit is designed for 120° viewing angle?

A: XTEAWT-00-0000-00000BGE4 provides 115° viewing angle versus the original 120°. This represents a 4.2% reduction in beam width. In applications requiring wide-angle distribution, this may affect illumination uniformity. Optical simulation or prototype testing is recommended for critical applications.

Q: What is the maximum current rating for each substitute?

A: XPGWHT-01-0000-00GE4, XPGWHT-01-0000-00GC3, XPGWHT-01-0000-00GD3, XPGWHT-01-0000-00GE5, and XPGWHT-01-0000-00GF5 all support 1.5A maximum. XTEAWT-00-0000-00000BGE4 also supports 1.5A. XPCWHT-L1-0000-00GE4 is limited to 0.5A. The original XPEHEW-01-0000-00GE4 supports 1.0A maximum.
