Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-006B7 is determined by the following critical parameters:
Electrical Compatibility:
- Flux output: 65 lm (62–67 lm range) at 350 mA test current
- Viewing angle: 90°
- Package type: 3529 (9073 Metric) surface mount
- Mounting footprint: 0.354" L × 0.276" W (9.00 mm × 7.00 mm)
- Height: 0.181" (4.60 mm) maximum seated height
Mechanical Compatibility:
- Surface mount configuration with identical footprint and height
- MSL rating: 4 (72 Hours)
- RoHS and REACH compliance maintained
All substitute parts listed below are from the XLamp® XR-E series, which shares identical package dimensions, flux output specifications, test current, viewing angle, and mounting characteristics. The primary difference is the forward voltage (3.3V for XR-E versus 4.6V for XR-C) and thermal resistance (8°C/W for XR-E versus 12°C/W for XR-C), both of which represent improvements in the newer series. All substitute parts maintain active product status.

Engineering Selection Recommendations
All listed XLamp® XR-E substitute parts are qualified replacements for XRCWHT-L1-0000-006B7 based on the following criteria:
Compliance & Certification: All substitute parts maintain RoHS Compliant and REACH Unaffected status, matching the original part's regulatory standing.
Product Status: The original XRCWHT-L1-0000-006B7 is obsolete. All substitute parts carry active product status, ensuring long-term availability and supply chain continuity.
Electrical & Mechanical Equivalence: Substitute parts deliver identical flux output (65 lm at 350 mA), viewing angle (90°), and package footprint (3529 / 9073 Metric). Forward voltage reduction from 4.6V to 3.3V and improved thermal resistance (8°C/W versus 12°C/W) represent performance enhancements in the XLamp® XR-E generation.
Moisture Sensitivity: All parts maintain MSL 4 (72 Hours) rating, requiring identical handling and storage protocols.
Selection among the nine available XR-E variants should be based on inventory availability and any specific color temperature or binning requirements defined by application requirements.
Frequently Asked Questions (FAQ)
Q: Can XLamp® XR-E parts directly replace XLamp® XR-C in existing designs?
A: Yes. The XR-E series maintains identical package dimensions (3529 / 9073 Metric), footprint (0.354" × 0.276"), height (0.181" max), and flux output (65 lm at 350 mA). The forward voltage difference (3.3V versus 4.6V) requires circuit-level verification to confirm driver compatibility, but mechanical and optical substitution is direct.
Q: What is the significance of the forward voltage difference?
A: The XR-C operates at 4.6V typical forward voltage, while XR-E operates at 3.3V. This 0.2V reduction affects power supply design and current limiting circuits. Designs using constant-current drivers will automatically compensate. Designs using series resistors may require recalculation to maintain target current at 350 mA.
Q: Are all nine XR-E variants electrically identical?
A: All nine XR-E substitute parts share identical electrical specifications: 3.3V forward voltage, 65 lm flux output at 350 mA, 56 lm/W efficiency, and 8°C/W thermal resistance. Differences in part number suffixes reflect internal binning or manufacturing lot designations and do not affect electrical or mechanical performance.
Q: Does the improved thermal resistance (8°C/W vs. 12°C/W) require design changes?
A: No design changes are required. The lower thermal resistance of XR-E represents an improvement that reduces junction temperature under identical operating conditions. This is a beneficial characteristic that enhances reliability and does not introduce compatibility issues.
Q: What packaging format is available for these parts?
A: All substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original XRCWHT-L1-0000-006B7 packaging format is not specified in the provided data.
Q: Are moisture sensitivity and compliance ratings identical?
A: Yes. All parts maintain MSL 4 (72 Hours), RoHS Compliant, and REACH Unaffected status. Storage, handling, and reflow protocols are identical across all parts listed.
