Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Color Temperature (CCT): 4250K ± tolerance
Flux Output: 126lm nominal at 350mA test current
Forward Voltage: Compatible with 3V nominal designs (2.85V to 3V acceptable)
Test Current: 350mA operation
Package / Case: 1414 (3535 Metric) surface mount
Viewing Angle: 120° ± 5° acceptable
CRI: 70 minimum
Thermal Resistance: Lower values indicate improved thermal performance

Substitutes are grouped into two categories:

Direct Series Equivalent: XTEAWT-00-0000-00000BFF5 (XLamp® XT-E series, active status, identical CCT and flux output)

Parametric Equivalents: XLamp® XP-G and XLamp® XP-C series parts with matching 4250K CCT, 126lm flux, 350mA test current, and 1414 package. These parts differ in forward voltage (2.9V), viewing angle (125°), and thermal characteristics but maintain functional equivalence for most applications.

Engineering Selection Recommendations

Primary Substitute: XTEAWT-00-0000-00000BFF5 (XLamp® XT-E series) is the recommended direct equivalent. It maintains identical CCT (4250K), flux output (126lm), test current (350mA), and package (1414), with active product status and RoHS compliance. Forward voltage is 2.85V, requiring minimal circuit adjustment. Thermal resistance improves to 5°C/W.

Secondary Substitutes: XLamp® XP-G series parts (XPGWHT-01-0000-00FF5, XPGWHT-01-R250-00FF5) provide parametric equivalence with superior thermal performance (4°C/W) and higher maximum current rating (1.5A). Forward voltage is 2.9V. Viewing angle increases to 125°. All XP-G variants are active and RoHS compliant.

Alternative: XPCWHT-L1-0000-00FF5 (XLamp® XP-C series) matches forward voltage (3V) and viewing angle (120°) but has reduced maximum current (500mA) and higher thermal resistance (8°C/W). Selection depends on thermal budget constraints.

Compliance Consideration: Substitutes with RoHS Compliant status are preferred for new designs. The main part status is not specified; active substitutes ensure long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can XTEAWT-00-0000-00000BFF5 directly replace XPEHEW-01-0000-00FF5?

A: Yes. Both parts share identical CCT (4250K), flux output (126lm at 350mA), test current (350mA), and 1414 package. Forward voltage differs by 0.15V (2.85V vs 3V), which is acceptable in most constant-current driver circuits. XTEAWT offers improved thermal performance (5°C/W vs 6°C/W) and active product status.

Q: What is the difference between XP-G and XP-E HEW series?

A: XP-G series offers lower forward voltage (2.9V vs 3V), superior thermal resistance (4°C/W vs 6°C/W), higher maximum current (1.5A vs 1A), and wider viewing angle (125° vs 120°). Flux output and CCT remain equivalent at 350mA test current.

Q: Are all substitute parts in 1414 package compatible with existing PCB layouts?

A: Yes. All listed substitutes use 1414 (3535 Metric) surface mount package with identical footprint dimensions (0.136" L x 0.136" W / 3.45mm x 3.45mm). Height variation ranges from 0.084" to 0.100", which is acceptable for standard reflow processes.

Q: Which substitute offers the best thermal performance?

A: XLamp® XP-G series parts (XPGWHT-01-0000-00FF5, XPGWHT-01-R250-00FF5) provide the lowest thermal resistance at 4°C/W, compared to 6°C/W for the main part and 5°C/W for XTEAWT.

Q: Do all substitutes have RoHS compliance?

A: XTEAWT-00-0000-00000BFF5 and all XP-G variants are RoHS Compliant. XPCWHT-L1-0000-00FF5 RoHS status is not specified in the provided data.

Q: What is the impact of forward voltage differences on circuit design?

A: Forward voltage differences (2.85V to 3V) require minimal adjustment in constant-current driver designs. Constant-voltage designs may require resistor recalculation. Verify driver specifications for acceptable forward voltage range.
