Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-00708 is determined by the following critical parameters:
Mechanical Compatibility: Package type (3529/9073 Metric), footprint dimensions (9.00mm x 7.00mm), and maximum seated height (4.60mm) must remain identical for PCB-level compatibility without layout modification.
Electrical Compatibility: Forward voltage (Vf), test current (350mA), and luminous flux output (71lm at 25°C) establish the functional operating envelope. Substitute parts must support the same test current and deliver equivalent or superior luminous output.
Optical Compatibility: Viewing angle (90°) and color (white) must be maintained for optical system performance.
Regulatory Compliance: RoHS compliance and REACH unaffected status must be preserved.
The XLamp® XR-E series parts listed below meet all mechanical and electrical substitution criteria. All substitute parts operate at 3.3V forward voltage (0.2V lower than the original), deliver 71lm at 350mA test current, maintain identical package geometry, and are active products with current manufacturing status.

Engineering Selection Recommendations
All listed XLamp® XR-E substitute parts are active products with current manufacturing status, eliminating obsolescence risk associated with the original XRCWHT-L1-0000-00708. All substitutes maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements.
The XR-E series delivers improved thermal performance (8°C/W versus 12°C/W), enabling better heat dissipation in thermal-constrained applications. Forward voltage reduction from 4.6V to 3.3V results in lower power consumption at equivalent current levels.
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 parametrically equivalent, each delivering 71lm at 350mA test current with identical mechanical and thermal characteristics. Selection among these variants depends on color temperature requirements not specified in the original part data.
XREWHT-L1-0000-00801 delivers superior luminous output (77lm versus 71lm) and efficiency (67 lm/W versus 58 lm/W) while maintaining identical package geometry and thermal performance. This part operates across the 5000K to 10000K color temperature range with 75 CRI typical and supports maximum current of 1A, providing additional design margin.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-007B1 through 007B9 be used interchangeably with XRCWHT-L1-0000-00708?
A: Yes. These parts share identical package geometry (3529/9073 Metric), footprint dimensions (9.00mm x 7.00mm), seated height (4.60mm), test current (350mA), and luminous output (71lm at 25°C). Forward voltage differs by 0.2V (3.3V versus 4.6V), requiring driver circuit adjustment. All parts are RoHS compliant with MSL 4 rating.
Q: What is the difference between XREWHT-L1-0000-00801 and the 007B series?
A: XREWHT-L1-0000-00801 delivers 77lm output versus 71lm for the 007B series, with efficiency of 67 lm/W versus 61 lm/W. It operates across 5000K to 10000K color temperature range with 75 CRI and supports maximum current of 1A. The 007B series variants are neutral or warm white without specified color temperature data. Both share identical package and thermal characteristics.
Q: Does the 0.2V forward voltage difference affect circuit design?
A: Yes. The XR-E series operates at 3.3V versus the original 4.6V. Driver circuits must be adjusted to accommodate this lower forward voltage. Total circuit voltage drop and current limiting resistor values require recalculation to maintain 350mA test current.
Q: Are all substitute parts currently available?
A: All listed XLamp® XR-E substitutes are active products with current manufacturing status. Inventory levels range from 725 to 1130 pieces across the 007B variants, with 1029 pieces available for XREWHT-L1-0000-00801.
Q: What is the thermal advantage of the XR-E series?
A: XR-E parts feature 8°C/W thermal resistance versus 12°C/W for the original XR-C part. This 33% improvement in thermal performance enables better heat dissipation and supports higher ambient temperature operation or higher current density applications.
Q: Do all substitutes maintain the same viewing angle?
A: Yes. All substitute parts maintain 90° viewing angle, preserving optical system performance and beam distribution characteristics.
