Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00803 is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts maintain identical package type (3529/9073 Metric), physical dimensions (9.00mm x 7.00mm), and maximum seated height (4.60mm), ensuring direct PCB footprint compatibility.

Electrical Compatibility: Substitute parts operate at the same test current (350mA), produce equivalent luminous flux (77lm at 25°C), maintain identical viewing angle (90°), and share the same CRI rating (75 Typ). Forward voltage differs minimally (3.3V vs. 4.6V), remaining within acceptable circuit design tolerances for LED applications.

Color Temperature Variants: Two substitute groups are available—6000K (cool white, matching the original specification) and 5000K (cool white, slightly warmer). Both are valid substitutes depending on application color temperature requirements.

Series Upgrade: All substitutes are from the XLamp® XR-E series, representing the active production equivalent to the obsolete XR-C series. The XR-E series provides improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (1A vs. 500mA).

Compliance & Certification: All substitute parts maintain RoHS compliance, identical MSL rating (4), and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000).

Parameter Comparison

Engineering Selection Recommendations

For 6000K Color Temperature Requirement: Select XREWHT-L1-0000-00803. This substitute maintains the exact color temperature specification of the original XRCWHT-L1-0000-00803 while providing active product status, improved thermal performance (8°C/W vs. 12°C/W), and higher maximum current capability (1A vs. 500mA). All mechanical and electrical parameters at nominal operating current (350mA) remain equivalent.

For 5000K Color Temperature Requirement: Select either XREWHT-L1-0000-008E3 or XREWHT-L1-R250-008E3. Both parts are functionally identical; selection between them depends on packaging preference (standard Tape & Reel vs. alternative reel configuration). The 5000K variant provides a slightly warmer color temperature while maintaining all other electrical and mechanical specifications.

Compliance & Regulatory: All substitute parts maintain RoHS compliance, identical MSL rating (4), and equivalent regulatory classifications. No additional qualification or testing is required from a compliance perspective.

Thermal Advantage: The XLamp® XR-E series substitutes offer superior thermal resistance (8°C/W), enabling better thermal management in high-density applications and reducing junction temperature rise compared to the obsolete XR-C series.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00803 be used as a direct replacement for XRCWHT-L1-0000-00803?

A: Yes. Both parts share identical package type (3529), physical dimensions (9.00mm x 7.00mm), viewing angle (90°), luminous flux (77lm at 350mA), and CRI rating (75). The forward voltage difference (3.3V vs. 4.6V) is within acceptable tolerance for LED circuit design. The substitute offers improved thermal performance and higher maximum current rating.

Q: What is the difference between the 6000K and 5000K substitute options?

A: XREWHT-L1-0000-00803 operates at 6000K (cool white, matching the original specification). XREWHT-L1-0000-008E3 and XREWHT-L1-R250-008E3 operate at 5000K (cool white, slightly warmer). All other electrical and mechanical parameters are identical. Selection depends on application color temperature requirements.

Q: Are there packaging differences between XREWHT-L1-0000-008E3 and XREWHT-L1-R250-008E3?

A: Both parts are supplied in Tape & Reel (TR) packaging. The part number suffix indicates different reel configurations. Electrical and mechanical specifications are identical; selection depends on manufacturing equipment compatibility and supply chain preference.

Q: Does the forward voltage difference (3.3V vs. 4.6V) affect circuit design?

A: The 0.2V difference is within normal LED tolerance and does not require circuit redesign for standard current-limiting applications. Verify that existing current-limiting resistor values remain appropriate for the substitute part's forward voltage. For precision applications, recalculate resistor values using the substitute's 3.3V specification.

Q: What is the thermal resistance improvement of the XR-E series?

A: The XLamp® XR-E series (all substitutes) provides 8°C/W thermal resistance compared to 12°C/W for the obsolete XR-C series. This 33% improvement reduces junction temperature rise, extending LED lifespan and enabling higher current operation within thermal limits.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (XREWHT-L1-0000-00803, XREWHT-L1-0000-008E3, XREWHT-L1-R250-008E3) are RoHS compliant with identical MSL rating (4, 72 Hours) and regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000).

Q: Can the substitute parts handle higher current than the original?

A: Yes. The XLamp® XR-E substitutes support maximum current of 1A compared to 500mA for the obsolete XR-C series. However, operation at the original test current (350mA) produces identical luminous flux and efficiency. Higher current operation requires thermal management verification and may alter color temperature characteristics.
