Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Substitution Criteria:

Color and CCT match (White, Neutral, 4750K preferred; adjacent CCT values 4300K–4750K acceptable)
Flux output within specified range (130–139 lm @ 25°C, 350mA)
Test current compatibility (350mA nominal)
Package compatibility (1414 / 3535 Metric)
Forward voltage within operational tolerance (2.85V–3V)
Viewing angle ≥ 120°
CRI ≥ 70

Secondary Criteria (Product Status & Compliance):

Active product status preferred for long-term availability
RoHS compliance status noted where applicable

The substitute parts are grouped into two categories:

Category 1: Direct Parametric Equivalents (XP-C and XP-G Series) Parts matching all primary criteria with identical or superior thermal performance and current handling.

Category 2: Functional Alternatives (XT-E Series) Parts meeting flux, voltage, and package requirements with minor parameter variations (lower Vf, higher max current, slightly lower viewing angle).

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

XPGWHT-01-0000-00GD1 and XPGWHT-01-0000-00GF4 (XLamp® XP-G series) are the preferred substitutes. Both parts deliver identical flux output (135 lm @ 350mA, 4750K) with improved thermal performance (4°C/W vs. 6°C/W), higher maximum current rating (1.5A vs. 1A), and active product status with RoHS compliance. The 0.1V reduction in forward voltage (2.9V vs. 3V) is within acceptable operational tolerance and reduces power dissipation. Viewing angle increases to 125°, providing broader light distribution.

XPCWHT-L1-0000-00GF4 (XLamp® XP-C series) matches all primary electrical parameters (3V Vf, 135 lm, 4750K, 120° viewing angle) and maintains identical footprint compatibility. This part is active and suitable where thermal performance is less critical (8°C/W thermal resistance). Maximum current is limited to 500mA, requiring circuit design consideration.

Secondary Substitute (Functional Alternative):

XTEAWT-00-0000-00000BGD1 (XLamp® XT-E series) meets flux and package requirements with lower forward voltage (2.85V), higher efficiency (135 lm/W), and superior thermal performance (5°C/W). The 115° viewing angle is slightly narrower than the main part. This part is active with RoHS compliance and Tape & Reel packaging.

Selection Criteria:

For thermal-constrained applications: XPGWHT-01-0000-00GD1 or XPGWHT-01-0000-00GF4
For voltage-sensitive designs: XPCWHT-L1-0000-00GF4 (3V match)
For efficiency-optimized designs: XTEAWT-00-0000-00000BGD1
For long-term supply assurance: All active alternatives provide equivalent availability

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-01-0000-00GD1 replace XPEHEW-01-0000-00GF4 directly?

A: Yes. Both parts deliver 135 lumens at 350mA in the 4750K neutral white spectrum with identical 1414 package footprint. The XP-G variant operates at 2.9V (vs. 3V) and provides superior thermal performance (4°C/W vs. 6°C/W). Circuit designs operating at 3V will function within tolerance; designs with strict voltage requirements should account for the 0.1V difference.

Q: What is the difference between XPGWHT-01-0000-00GD1 and XPGWHT-01-0000-00GF4?

A: Both are XLamp® XP-G parts with identical electrical and thermal specifications. The difference lies in internal binning or manufacturing date codes. Both are suitable substitutes for the obsolete XPEHEW-01-0000-00GF4.

Q: Why does XPCWHT-L1-0000-00GF4 have a higher thermal resistance (8°C/W)?

A: The XP-C series uses a different die and package architecture than the XP-E HEW and XP-G series. While thermal resistance is higher, the part remains suitable for applications where junction temperature rise is acceptable. Maximum current is limited to 500mA to manage thermal output.

Q: Is XTEAWT-00-0000-00000BGD1 compatible with existing PCB layouts?

A: Yes. The XT-E part uses the same 1414 (3535 Metric) package and footprint. Height is 0.100" (2.54mm) vs. 0.087" (2.21mm) for the main part; verify clearance in applications with tight vertical constraints. Forward voltage is 2.85V, requiring circuit verification for voltage-sensitive designs.

Q: What is the impact of the 125° viewing angle in XP-G substitutes vs. 120° in the main part?

A: The wider 125° viewing angle provides broader light distribution with no negative impact on direct replacement applications. Applications requiring narrower beam concentration should account for this difference in optical design.

Q: Are all substitute parts RoHS compliant?

A: XPGWHT-01-0000-00GD1, XPGWHT-01-0000-00GF4, and XTEAWT-00-0000-00000BGD1 are RoHS compliant. XPCWHT-L1-0000-00GF4 RoHS status is not specified in the provided data. Verify compliance requirements with your procurement process.

Q: Can I use XPGWHT-01-0000-00GE4 or XPGWHT-01-0000-00GE5 as substitutes?

A: XPGWHT-01-0000-00GE4 operates at 4500K (vs. 4750K required). XPGWHT-01-0000-00GE5 operates at 4000K. Both deliver 135 lumens at 350mA with identical thermal and electrical performance. Use only if CCT tolerance permits deviation from 4750K specification.
