The three substitute parts (XREWHT-L1-0000-004E7, XREWHT-L1-0000-004E8, XREWHT-L1-0000-004F8) are all from the active XLamp® XR-E series. While they differ in CCT (color temperature), they maintain identical flux output and mechanical form factor, allowing substitution based on application color temperature requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XREWHT-L1-0000-004E7

This part is the direct equivalent for the XRCWHT-L1-0000-004E7. It maintains identical CCT (3000K), flux output, and viewing angle specifications. The XLamp® XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA), providing enhanced design margin. Active product status ensures long-term availability and supply chain continuity.

Alternative Substitutes: XREWHT-L1-0000-004E8 and XREWHT-L1-0000-004F8

These parts are suitable when application color temperature requirements permit deviation from the original 3000K specification. Both maintain identical flux output (54lm), CRI (80), and mechanical form factor. XREWHT-L1-0000-004E8 (2700K) provides warmer color rendering, while XREWHT-L1-0000-004F8 (2900K) offers an intermediate option. Both are active products with superior thermal characteristics.

All substitute parts maintain RoHS compliance and MSL rating consistency with the original component, ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-004E7 be used as a direct replacement for XRCWHT-L1-0000-004E7?

A: Yes. Both parts share identical CCT (3000K), flux output (54lm @ 350mA), CRI (80), viewing angle (90°), and 3529 package dimensions. The XR-E substitute offers improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA). Forward voltage differs slightly (3.3V vs. 4.6V), which is within acceptable operating range for most applications.

Q: What is the difference between the three substitute parts?

A: All three substitutes (XREWHT-L1-0000-004E7, XREWHT-L1-0000-004E8, XREWHT-L1-0000-004F8) are mechanically and electrically identical except for color temperature (CCT). XREWHT-L1-0000-004E7 matches the original 3000K specification. XREWHT-L1-0000-004E8 provides 2700K (warmer), and XREWHT-L1-0000-004F8 provides 2900K (intermediate). Flux output remains constant at 54lm across all variants.

Q: Are there any thermal design considerations when substituting?

A: The substitute parts feature improved thermal resistance (8°C/W vs. 12°C/W), which reduces junction temperature rise under identical operating conditions. This improvement allows for higher current operation or reduced thermal management requirements. No design modifications are necessary; the improved thermal performance is a benefit.

Q: Will the lower forward voltage of the substitute parts affect circuit design?

A: The substitute parts operate at 3.3V typical forward voltage compared to 4.6V for the original. This 0.2V difference is within normal LED operating tolerances and does not require circuit redesign for most applications. Verify that your current-limiting circuit accommodates the voltage range of 3.3V to 4.6V.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for SMD components. The 3529 (9073 Metric) package dimensions are identical across all parts, ensuring compatibility with existing pick-and-place equipment and PCB layouts.

Q: What is the inventory status of the substitute parts?

A: XREWHT-L1-0000-004E7: 1121 Pcs in stock. XREWHT-L1-0000-004E8: 1088 Pcs in stock. XREWHT-L1-0000-004F8: 1019 Pcs in stock. All substitute parts are active products with established supply chains.
