Engineering Selection Recommendations

All listed XLamp® XR-E substitute parts are classified as active products, ensuring ongoing availability and supply chain stability. The XR-E series provides improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficiency (73 lm/W vs. 69 lm/W) compared to the obsolete XR-C series.

Forward voltage differs by 0.2V (3.3V vs. 4.6V), which requires circuit verification to confirm compatibility with existing current-limiting designs. All substitute parts maintain identical mechanical footprint, luminous flux output, viewing angle, and compliance certifications (RoHS, REACH, MSL 4).

Selection among substitute parts depends on specific color temperature or binning requirements not differentiated in the provided data. XREWHT-L1-0000-009A4 specifies 4000K neutral white color temperature. All other variants are designated as cool white or neutral white without explicit CCT specification.

Frequently Asked Questions (FAQ)

Q: Can XLamp® XR-E parts directly replace the obsolete XLamp® XR-C XRCWHT-L1-0000-009B3?

A: Yes, from a mechanical and optical standpoint. All substitute parts share identical 3529 package dimensions, footprint, seated height, viewing angle (90°), and luminous flux output (84lm @ 350mA). However, forward voltage differs by 0.2V (3.3V vs. 4.6V), requiring circuit-level verification to confirm compatibility with existing current-limiting resistor or driver designs.

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

A: All substitute parts are from the XLamp® XR-E series with identical electrical and mechanical specifications. Differences are limited to color temperature binning or internal product variants not explicitly detailed in the provided parameters. XREWHT-L1-0000-009A4 is specified as 4000K neutral white; others are designated as cool white or neutral white without explicit CCT values.

Q: Are there thermal performance differences?

A: Yes. The XR-E substitute parts feature improved thermal resistance of 8°C/W compared to the XR-C original part at 12°C/W. This represents a 33% reduction in thermal resistance, enabling better heat dissipation and potentially lower junction temperatures under identical operating conditions.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are RoHS Compliant, REACH Unaffected, and classified as MSL 4 (72 Hours), matching the compliance profile of the original XRCWHT-L1-0000-009B3.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original part was supplied without specified packaging designation.

Q: How does efficiency compare between the original and substitute parts?

A: XLamp® XR-E substitute parts deliver 73 lm/W compared to 69 lm/W for the original XR-C part, representing a 5.8% efficiency improvement at identical test current (350mA) and luminous flux output.
