Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

Color and CCT (Correlated Color Temperature): All substitutes must be neutral white at 4300K or within the 4000–4300K range to maintain color consistency in lighting applications.
Flux Output: Substitutes must deliver 126 lm (122–130 lm range) at the 350 mA test current to ensure equivalent brightness.
Test Current and Maximum Current: All substitutes operate at 350 mA test current; maximum current ratings may vary (1.0 A to 1.5 A) without affecting substitution validity.
Forward Voltage (Vf): Acceptable range is 2.85 V to 3.05 V; minor variations are acceptable within circuit design tolerances.
Package and Mounting: All substitutes use the 1414 (3535 Metric) surface mount package with identical footprint and land pattern.
CRI: All substitutes maintain CRI of 70 (Typical).
Viewing Angle: Substitutes range from 115° to 125°; minor angle variations are acceptable for general lighting applications.

Substitutes are grouped into two categories:

Similar Manufacturer Part (XT-E Series): XTEAWT-00-0000-00000BFC3 — Active product with slightly lower forward voltage (2.85 V) and higher maximum current rating (1.5 A).
Parametric Equivalents (XP-E and XP-G Series): Five active XP-E and XP-G variants meeting all critical electrical and mechanical parameters.

Engineering Selection Recommendations

Primary Recommendation: XPGWHT-01-0000-00FC3 or XPGWHT-01-R250-00FC3

Both XP-G variants are active products with RoHS compliance. They deliver identical flux output (126 lm) and CCT (4300K) at 350 mA test current. The XP-G series offers superior thermal performance (4°C/W versus 6°C/W) and higher maximum current rating (1.5 A), providing design margin for thermal management and current headroom. Viewing angle increases from 120° to 125°, which is acceptable for general lighting applications.

Secondary Recommendation: XPEWHT-01-0000-00FC3 or XPEWHT-01-R250-00FC3

Both XP-E variants are active products with RoHS compliance and maintain the same flux output and CCT. Forward voltage is slightly higher (3.05 V versus 3.0 V), requiring minor circuit adjustment. Thermal resistance is higher (9°C/W), necessitating careful thermal design. Viewing angle is 115°, slightly narrower than the main part.

Alternative Recommendation: XTEAWT-00-0000-00000BFC3

The XT-E variant is an active product with RoHS compliance and superior thermal performance (5°C/W). Forward voltage is lower (2.85 V), reducing power dissipation. Maximum current rating is higher (1.5 A). This part is suitable for applications where lower forward voltage and improved thermal characteristics are beneficial.

All substitute parts are available in active production status with RoHS compliance, ensuring long-term supply and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-01-0000-00FC3 be used as a direct replacement for XPEHEW-01-0000-00FC3?

A: Yes. Both parts deliver 126 lm at 4300K with 350 mA test current in the same 1414 (3535 Metric) package. The XP-G variant has a slightly wider viewing angle (125° versus 120°) and superior thermal performance (4°C/W versus 6°C/W). Forward voltage is lower (2.9 V versus 3.0 V), which may require minor circuit adjustment depending on the driver design.

Q: What is the difference between XPEWHT-01-0000-00FC3 and XPEWHT-01-R250-00FC3?

A: Both parts are electrically and optically identical. The "-R250-" designation indicates a 250-unit reel packaging option, while the base part uses standard packaging. Electrical performance, flux output, and thermal characteristics are identical.

Q: Does the viewing angle difference (120° to 115° or 125°) affect substitution?

A: Viewing angle variations within this range are acceptable for general lighting applications. Narrower angles (115°) concentrate light more intensely, while wider angles (125°) provide broader distribution. Application-specific optical design should be evaluated, but the parts are mechanically and electrically compatible.

Q: Why is XTEAWT-00-0000-00000BFC3 listed as a similar part rather than a parametric equivalent?

A: The XT-E series represents a different product line within the XLamp family. While it meets all critical substitution criteria (flux, CCT, package, current), it is classified separately due to its distinct series designation and slightly different electrical characteristics (2.85 V forward voltage versus 3.0 V).

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts (XTEAWT, XPEWHT, XPGWHT variants) are RoHS compliant. The main part (XPEHEW-01-0000-00FC3) does not specify RoHS status due to its obsolete classification.

Q: What is the impact of thermal resistance differences on circuit design?

A: Lower thermal resistance (4°C/W for XP-G versus 6°C/W for XP-E HEW) indicates better heat dissipation. This reduces junction temperature at the same power dissipation, improving reliability and light output stability. Higher thermal resistance (9°C/W for some XP-E variants) requires more careful thermal management through PCB design and heat sinking.

Q: Can I use XPGWHT-01-0000-00FC4 or other CCT variants as substitutes?

A: No. The main part is specified at 4300K. Variants with different CCT designations (4100K, 4000K, 4250K) have different color temperatures and are not interchangeable without affecting the intended lighting color characteristics.
