Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-007B5 is determined by the following critical parameters:
Electrical Compatibility:
- Luminous flux at 25°C and 350 mA test current: 71 lm (67–74 lm range)
- Viewing angle: 90°
- Color: White
- Mounting type: Surface Mount
- Package / Case: 3529 (9073 Metric)
- Physical dimensions: 0.354" L × 0.276" W (9.00 mm × 7.00 mm)
- Height - Seated (Max): 0.181" (4.60 mm)
Regulatory & Environmental:
- RoHS Compliance: Required
- REACH Status: Unaffected
- Moisture Sensitivity Level: 4 (72 Hours)
All substitute parts listed below are from the CreeLED XLamp® XR-E series. While the XR-E series operates at a lower typical forward voltage (3.3V vs. 4.6V), it maintains identical luminous flux output, viewing angle, package dimensions, and regulatory compliance. The XR-E series offers improved thermal resistance (8°C/W vs. 12°C/W) and active product status.

Engineering Selection Recommendations
All XLamp® XR-E substitute parts listed maintain full compatibility with the XRCWHT-L1-0000-007B5 footprint and electrical performance envelope. The primary design consideration is the forward voltage differential: XR-E parts operate at 3.3V typical versus 4.6V for the XR-C original. This 0.2V reduction results in improved efficiency (61 lm/W vs. 58 lm/W) and lower thermal resistance (8°C/W vs. 12°C/W).
All substitute parts carry active product status from CreeLED, ensuring long-term availability and supply chain continuity. All parts maintain identical RoHS compliance, REACH unaffected status, and MSL 4 moisture sensitivity classification.
For applications requiring warm white color temperature specification, XREWHT-L1-0000-007AA (2700K CCT) provides explicit color temperature definition. For neutral white applications without specific CCT requirement, XREWHT-L1-0000-007B1, XREWHT-L1-0000-007B3, XREWHT-L1-0000-007B5, XREWHT-L1-0000-007B6, XREWHT-L1-0000-007B7, XREWHT-L1-0000-007B8, and XREWHT-L1-0000-007B9 are functionally equivalent.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-007B5 (XR-E) directly replace XRCWHT-L1-0000-007B5 (XR-C) without circuit modification?
A: Direct mechanical and thermal substitution is supported. The 0.2V forward voltage reduction (3.3V vs. 4.6V) may require minor current-limiting resistor adjustment in series-resistor-driven designs to maintain identical brightness. Constant-current driver circuits require no modification.
Q: What is the difference between XREWHT-L1-0000-007AA and other XR-E substitutes?
A: XREWHT-L1-0000-007AA is specified as 2700K warm white with explicit color temperature definition. Other XR-E parts (007B1 through 007B9) are specified as neutral white without CCT designation. All maintain identical luminous flux, electrical, and mechanical parameters.
Q: Are all substitute parts available in the same packaging format?
A: Yes. All XR-E substitute parts are supplied in Tape & Reel (TR) packaging. The original XRCWHT-L1-0000-007B5 packaging format is not specified in the provided data. All parts use identical 3529 (9073 Metric) package / case configuration.
Q: What is the thermal performance improvement of XR-E substitutes?
A: XR-E parts provide 8°C/W thermal resistance compared to 12°C/W for the original XR-C part, representing a 33% improvement in thermal performance. This enables higher sustained brightness or lower junction temperature operation.
Q: Do all substitute parts meet the same regulatory requirements?
A: Yes. All XLamp® XR-E substitute parts are RoHS Compliant, REACH Unaffected, and classified as MSL 4 (72 Hours) moisture sensitivity, matching the original part specifications.
