Substitute Part Grouping Explanation
Substitution of the XRCWHT-L1-0000-005E6 is based on the following criteria:
Mechanical Compatibility: All substitute parts maintain identical package dimensions (3529 / 9073 Metric), footprint (0.354" × 0.276"), and maximum seated height (4.60mm), ensuring direct PCB compatibility without layout modifications.
Electrical Compatibility: Substitute parts operate at the same test current (350mA) and produce identical luminous flux (59 lm at 25°C). Forward voltage differs slightly (3.3V vs. 4.6V), which is within acceptable circuit design tolerance for LED applications using current-limiting resistors or constant-current drivers.
Thermal Characteristics: XLamp® XR-E substitutes feature improved thermal resistance (8°C/W vs. 12°C/W), providing superior thermal performance in the same package footprint.
Color Temperature Options: Substitutes are available across the warm white spectrum (2700K, 2900K, 3000K, 3200K, 3500K), allowing selection based on application requirements while maintaining identical optical and electrical performance at rated current.
Product Status & Compliance: All substitute parts are active products with current manufacturing status, RoHS compliance, and REACH unaffected designation, ensuring supply chain continuity and regulatory compliance.
Packaging Variants: Substitutes are available in both Tape & Reel (TR) packaging configurations, with part number suffixes indicating packaging type (e.g., -L1-0000- vs. -L1-R250-).

Engineering Selection Recommendations
Direct Replacement (3500K Match): XREWHT-L1-0000-005E6 is the primary substitute for the obsolete XRCWHT-L1-0000-005E6, maintaining identical color temperature (3500K) and luminous flux (59 lm). This part is active and carries full RoHS and REACH compliance. The 0.2V reduction in forward voltage (3.3V vs. 4.6V) is accommodated by standard current-limiting circuit design and does not affect optical performance at rated current.
Alternative Color Temperatures: When application requirements permit color temperature variation, XLamp® XR-E substitutes are available across the warm white spectrum: XREWHT-L1-0000-005E7 (3000K), XREWHT-L1-0000-005E8 (2700K), XREWHT-L1-0000-005F7 (3200K), and XREWHT-L1-0000-005F8 (2900K). All maintain identical luminous flux, test current, and mechanical compatibility.
Packaging Selection: Substitutes are available in standard Tape & Reel (TR) packaging (part numbers with -L1-R250- designation) or alternative packaging configurations (part numbers with -L1-0000- designation). Selection depends on procurement and assembly requirements.
Thermal Performance Advantage: All XLamp® XR-E substitutes provide improved thermal resistance (8°C/W vs. 12°C/W), resulting in lower junction temperatures under identical operating conditions and enhanced reliability in thermally constrained applications.
Current Rating Upgrade: XLamp® XR-E series supports maximum current of 700mA compared to 500mA for the XR-C series, enabling higher brightness operation if circuit design permits.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-005E6 be used as a direct replacement for XRCWHT-L1-0000-005E6?
A: Yes. Both parts produce 59 lumens at 350mA test current, operate at 90° viewing angle, and share identical 3529 package dimensions and thermal footprint. The forward voltage difference (3.3V vs. 4.6V) is managed through standard current-limiting circuit design and does not affect optical output at rated current.
Q: What is the impact of the 0.2V forward voltage difference?
A: The forward voltage reduction from 4.6V to 3.3V results in lower power dissipation in the LED itself. For circuits using current-limiting resistors or constant-current drivers, this difference is automatically compensated by the current control mechanism. Total circuit voltage drop remains within acceptable design margins for standard 5V and 12V supply systems.
Q: Are all substitute parts available in the same packaging options?
A: Substitute parts are available in two packaging configurations: standard packaging (part numbers with -L1-0000- designation) and Tape & Reel packaging (part numbers with -L1-R250- designation). Selection depends on procurement volume and assembly process requirements.
Q: Can I select a different color temperature substitute?
A: Yes. All XLamp® XR-E warm white substitutes (2700K, 2900K, 3000K, 3200K, 3500K) maintain identical luminous flux (59 lm), test current (350mA), and mechanical compatibility. Color temperature selection depends on application lighting requirements and is independent of electrical or mechanical compatibility.
Q: What is the advantage of the improved thermal resistance in XLamp® XR-E?
A: The 8°C/W thermal resistance of XR-E substitutes compared to 12°C/W for the obsolete XR-C results in lower junction temperature rise under identical operating conditions. This provides improved reliability, extended operational life, and better performance in thermally constrained PCB layouts.
Q: Are all substitute parts RoHS and REACH compliant?
A: Yes. All XLamp® XR-E substitute parts carry RoHS Compliant status and REACH Unaffected designation, matching the compliance profile of the original XRCWHT-L1-0000-005E6 and ensuring regulatory compliance for new designs and production.
Q: What is the moisture sensitivity level for these parts?
A: All parts, including the main part and all substitutes, carry MSL 4 (72 Hours) rating. This requires storage in controlled humidity environments and standard moisture-barrier packaging during transport and storage.
