Substitute Part Grouping Explanation

Substitution eligibility for XRCWHT-L1-0000-007A1 is determined by the following critical parameters:

• Color Temperature (CCT): Must be 5000K (Cool White)
• Luminous Flux @ 25°C, 350mA: Must be within 67lm ~ 74lm range
• Test Current: Must be 350mA
• Viewing Angle: Must be 90°
• Package / Case: Must be 3529 (9073 Metric)
• Mounting Type: Must be Surface Mount (SMD)
• Physical Dimensions: Must match 9.00mm x 7.00mm footprint and 4.60mm max height
• Compliance: Must maintain RoHS Compliant and MSL 4 status

The substitute parts identified below meet these criteria. Forward voltage variation (3.3V vs 4.6V) is acceptable within the XLamp® product family design specifications for this package category, as both operate at the same test current and deliver equivalent luminous output.

Parameter Comparison

Engineering Selection Recommendations

Both XREWHT-L1-0000-007A1 and XREWHT-L1-0000-007E3 are active product alternatives to the obsolete XRCWHT-L1-0000-007A1. Selection between these two XLamp® XR-E variants should be based on:

XREWHT-L1-0000-007A1 is suitable for applications where CRI specification is not required and maximum current rating is not a design constraint.

XREWHT-L1-0000-007E3 is suitable for applications requiring CRI 75 (Typ) color rendering performance and higher maximum current capability (1A vs unspecified). This variant also provides improved thermal resistance (8°C/W vs 12°C/W in the original part), resulting in better thermal management in high-density applications.

Both substitutes maintain RoHS Compliance and MSL 4 rating, ensuring compatibility with standard surface mount assembly processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007A1 or XREWHT-L1-0000-007E3 be used as direct replacements for XRCWHT-L1-0000-007A1?

A: Yes. Both parts deliver identical luminous flux (71lm) at the specified test current (350mA) and operate at the same color temperature (5000K). The forward voltage difference (3.3V vs 4.6V) is within acceptable design margins for the 3529 package category. Both are mounted in identical 9.00mm x 7.00mm footprints with matching height specifications.

Q: What is the significance of the forward voltage difference between the main part (4.6V) and the substitutes (3.3V)?

A: The 0.2V difference reflects the evolution between XLamp® XR-C and XR-E series designs. Both operate at 350mA test current and produce equivalent luminous output. Circuit designs using current-limiting resistors or constant-current drivers will accommodate this variation without performance degradation.

Q: Why does XREWHT-L1-0000-007E3 have a CRI specification while XREWHT-L1-0000-007A1 does not?

A: CRI (Color Rendering Index) is a measured parameter provided by the manufacturer when available. XREWHT-L1-0000-007E3 includes CRI 75 (Typ) specification; XREWHT-L1-0000-007A1 does not list this parameter. Both parts maintain the same 5000K color temperature and luminous output.

Q: What is the difference in thermal resistance between these parts?

A: The original XRCWHT-L1-0000-007A1 has 12°C/W thermal resistance, while both XR-E substitutes have 8°C/W. Lower thermal resistance indicates improved heat dissipation. This enhancement in the XR-E series allows for better thermal performance in applications with sustained high-current operation or elevated ambient temperatures.

Q: Are there packaging differences between these parts?

A: The original part packaging is listed as "-" (unspecified). Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. This packaging format is compatible with automated pick-and-place equipment.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are RoHS Compliant, carry MSL 4 (72 Hours) moisture sensitivity rating, and are REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.
