Substitute Part Grouping Explanation
Substitution of XRCWHT-L1-0000-005B6 is based on the following critical parameters that must remain constant or compatible:
Mechanical Compatibility:
- Package type: 3529 (9073 Metric) — all substitutes maintain identical package
- Mounting type: Surface Mount — all substitutes are surface mount
- Physical dimensions: 9.00 mm × 7.00 mm footprint and 4.60 mm seated height — all substitutes match exactly
- Viewing angle: 90° — all substitutes maintain this specification
Electrical Compatibility:
- Flux output: 59 lm (57–62 lm range) @ 25°C, 350 mA test current — all substitutes deliver identical flux
- Test current: 350 mA — all substitutes rated for this current
- Lumens/Watt efficiency: 51 lm/W (substitutes) vs. 48 lm/W (original) — substitutes provide improved efficiency
- Forward voltage: 3.3 V (substitutes) vs. 4.6 V (original) — lower voltage reduces power dissipation

Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-005B6 directly replace XRCWHT-L1-0000-005B6 on existing PCBs?
A: Yes. Both parts use identical 3529 (9073 Metric) package with matching footprint (9.00 mm × 7.00 mm) and seated height (4.60 mm). No PCB layout modifications are required. The lower forward voltage (3.3 V vs. 4.6 V) reduces power dissipation and improves efficiency.
Q: What is the difference between XREWHT-L1-0000-005B6 and XREWHT-L1-R250-005B6?
A: Both parts maintain identical electrical specifications, optical output (59 lm), forward voltage (3.3 V), and package configuration. The "-R250-" designation indicates alternative thermal or performance binning. Selection depends on specific application requirements and inventory availability. Maximum current specification is not provided for R250 variants.
Q: Is XREWHT-L1-0000-005E8 suitable for applications requiring neutral white light?
A: XREWHT-L1-0000-005E8 is specified as warm white (2700K CCT). For neutral white applications, use XREWHT-L1-0000-005B6, XREWHT-L1-0000-005B7, XREWHT-L1-0000-005B8, or XREWHT-L1-0000-005B9, which do not specify CCT and are suitable for standard white applications.
Q: What are the thermal advantages of the XR-E substitutes?
A: XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to 12°C/W for the original XR-C part. This 33% improvement in thermal performance enables better heat dissipation and supports higher current operation (700 mA vs. 500 mA maximum), extending design flexibility for thermal-constrained applications.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All listed XLamp® XR-E substitutes are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original XRCWHT-L1-0000-005B6 packaging format is not specified in the provided data.
Q: Do the substitute parts maintain compliance certifications?
A: Yes. All XLamp® XR-E substitutes are RoHS Compliant, REACH Unaffected, and rated MSL 4 (72 Hours), matching the compliance profile of the original part.
