Substitute Part Grouping Explanation

Substitute parts are grouped based on the following critical parameters that determine functional compatibility:

Color temperature: 4500K (primary) or 4300K (acceptable variance)
Flux output: 126lm ± tolerance at test current
Test current: 350mA
Forward voltage: 3V nominal (tolerance range 2.85V to 3.05V acceptable)
Package: 1414 (3535 Metric) surface mount
CRI: 70 (Typ)
Viewing angle: 115° to 125° (acceptable variance from 120°)

All substitute parts maintain the same footprint, mounting type, and luminous flux specification. Variations in forward voltage, thermal resistance, and maximum current rating reflect improvements in LED technology across different XLamp® series generations.

Engineering Selection Recommendations

All listed substitute parts are active products from CreeLED's current XLamp® portfolio and are suitable for direct replacement of the obsolete XPEHEW-01-0000-00FE4 based on matching electrical and mechanical specifications.

XLamp® XT-E (XTEAWT-00-0000-00000BFD2): Active status with RoHS compliance. Lower forward voltage (2.85V) and improved thermal resistance (5°C/W) compared to the original part. Higher maximum current rating (1.5A) provides design margin.

XLamp® XP-C (XPCWHT-L1-0000-00FE4): Active status. Identical forward voltage (3V) and viewing angle (120°) to the original part. Lower maximum current rating (500mA) requires verification against application requirements.

XLamp® XP-E Series (XPEWHT variants): Active status with RoHS compliance. Forward voltage 3.05V with multiple part number variants supporting both 4500K and 4300K color temperatures. Tape & Reel packaging available. Viewing angle 115° represents minor deviation from original 120°.

XLamp® XP-G Series (XPGWHT variants): Active status with RoHS compliance. Lowest forward voltage (2.9V) and thermal resistance (4°C/W) with highest efficiency (124 lm/W). Supports both 4500K and 4300K color temperatures. Higher maximum current rating (1.5A).

All substitute parts maintain 1414 (3535 Metric) package footprint, 126lm flux output at 350mA test current, and CRI 70 specification.

Frequently Asked Questions (FAQ)

Q: Can XPEWHT-01-0000-00FD2 directly replace XPEHEW-01-0000-00FE4?

A: Yes. Both parts maintain 4500K color temperature, 126lm flux output at 350mA, 1414 package footprint, and compatible forward voltage (3V vs. 3.05V). The XPEWHT variant is active and available in Tape & Reel packaging.

Q: What is the difference between 4500K and 4300K variants?

A: Color temperature difference of 200K. Both are neutral white LEDs with identical flux, current, and package specifications. Selection depends on application color temperature requirement. 4500K variants are listed as primary equivalents; 4300K variants (XPEWHT-01-0000-00FC3, XPEWHT-01-R250-00FC3, XPGWHT-01-0000-00FC3) are acceptable alternatives if color temperature tolerance permits.

Q: Why do substitute parts have different forward voltages?

A: Forward voltage variations (2.85V to 3.05V) reflect improvements in LED die and package technology across different XLamp® series generations. All values remain within acceptable operating range for standard LED driver circuits designed for 3V nominal operation.

Q: Does the viewing angle difference (120° vs. 115° or 125°) affect compatibility?

A: Viewing angle differences of ±5° to ±10° are minor and do not affect optical system compatibility in most applications. Verify against specific application requirements if precise beam pattern is critical.

Q: What is the significance of Tape & Reel (TR) packaging?

A: Tape & Reel packaging indicates automated pick-and-place assembly compatibility. The original XPEHEW part does not specify packaging format. XPEWHT and XPGWHT variants with TR designation are suitable for high-volume manufacturing processes.

Q: Are all substitute parts RoHS compliant?

A: XTEAWT-00-0000-00000BFD2, XPEWHT series, and XPGWHT series are RoHS compliant. XPCWHT-L1-0000-00FE4 does not specify RoHS status in provided data. Verify compliance requirements for your application.

Q: What thermal considerations apply when substituting parts?

A: Thermal resistance varies from 4°C/W (XPGWHT) to 9°C/W (XPEWHT). Lower thermal resistance indicates better heat dissipation. If thermal management is critical, XPGWHT or XTEAWT variants offer improved performance. Verify PCB thermal design accommodates the selected part's thermal characteristics.

Q: Can I use XPCWHT-L1-0000-00FE4 if my application requires 1A maximum current?

A: No. XPCWHT-L1-0000-00FE4 has a maximum current rating of 500mA, which is insufficient for applications requiring 1A operation. Use XPEWHT or XPGWHT variants instead, which support 1A or 1.5A maximum current.
