Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-00705 is determined by the following critical parameters:
Mechanical Compatibility: Package type (3529/9073 Metric), physical dimensions (9.00mm x 7.00mm), and height (4.60mm maximum) must remain identical for PCB footprint compatibility.
Electrical Compatibility: Forward voltage tolerance, test current rating (350mA), and maximum current rating must support existing circuit design without requiring modifications to current-limiting resistors or power supply specifications.
Optical Performance: Luminous flux output at 25°C and 350mA test current must fall within the specified range (67lm ~ 74lm) to maintain brightness consistency in the application.
Viewing Angle: 90° viewing angle specification must be maintained for optical system alignment.
Environmental Compliance: RoHS compliance and MSL rating (4, 72 Hours) must match or exceed the original specification.
All substitute parts listed are from the active XLamp® XR-E series, which shares identical mechanical packaging and mounting characteristics with the obsolete XR-C series while providing improved thermal performance and higher efficiency ratings.

Engineering Selection Recommendations
Primary Substitute: XREWHT-L1-0000-007B1, XREWHT-L1-0000-007B2, XREWHT-L1-0000-007B3, XREWHT-L1-0000-007B4, XREWHT-L1-0000-007B5, XREWHT-L1-0000-007B6, XREWHT-L1-0000-007B7, XREWHT-L1-0000-007B8, and XREWHT-L1-0000-007B9 are parametric equivalents with identical luminous flux output (71lm at 350mA, 25°C) and matching mechanical specifications. These parts are active products with RoHS compliance and MSL 4 rating. The 0.2V reduction in forward voltage (3.3V vs. 4.6V) requires circuit verification to confirm current-limiting resistor values remain appropriate for the application.
Alternative Substitute: XREWHT-L1-0000-00801 provides higher luminous flux output (77lm) and improved efficiency (67 lm/W), with extended color temperature range (5000K ~ 10000K). This part is suitable for applications where increased brightness is acceptable and circuit design permits the lower forward voltage specification. CRI rating of 75 (Typ) is provided for this variant.
Compliance Verification: All substitute parts maintain RoHS compliance and MSL 4 (72 Hours) moisture sensitivity rating, ensuring compatibility with existing supply chain and assembly processes. Thermal resistance improvement (8°C/W vs. 12°C/W) in XR-E series provides enhanced thermal performance for high-density applications.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-007B series parts be used as direct drop-in replacements?
A: Yes, for mechanical and optical compatibility. The 0.2V forward voltage reduction (3.3V vs. 4.6V) requires circuit analysis. If the original design uses a fixed current-limiting resistor, the lower forward voltage will increase LED current at the same supply voltage. Recalculate resistor values or verify the circuit design accommodates this voltage difference.
Q: What is the difference between XREWHT-L1-0000-00801 and the XREWHT-L1-0000-007B series?
A: XREWHT-L1-0000-00801 delivers higher luminous flux (77lm vs. 71lm) and efficiency (67 lm/W vs. 61 lm/W), with specified color temperature range (5000K ~ 10000K) and CRI rating (75 Typ). The 007B series maintains identical flux output to the original part. Selection depends on application brightness requirements and color rendering specifications.
Q: Are all substitute parts available in the same packaging?
A: Yes. All substitute parts use 3529 (9073 Metric) surface mount package with identical dimensions (9.00mm x 7.00mm) and height (4.60mm maximum), ensuring PCB footprint compatibility without layout modifications.
Q: What is the impact of improved thermal resistance in XR-E series?
A: XR-E thermal resistance (8°C/W) is superior to XR-C (12°C/W), resulting in lower junction temperature at equivalent power dissipation. This improves reliability and extends component lifespan in thermally constrained applications.
Q: Do all substitute parts meet the same compliance standards?
A: Yes. All listed substitute parts are RoHS compliant with MSL 4 (72 Hours) moisture sensitivity rating, matching the original part's environmental compliance profile.
Q: What viewing angle do all substitute parts maintain?
A: All substitute parts maintain 90° viewing angle specification, ensuring optical system compatibility without beam pattern modifications.
