Engineering Selection Recommendations
All listed substitute parts are active production components from the CreeLED XLamp® XR-E series and maintain full RoHS compliance and REACH unaffected status. The XR-E series represents the current generation replacement for the obsolete XR-C series.
Direct Substitution Candidates: XREWHT-L1-0000-00905, XREWHT-L1-0000-00907, XREWHT-L1-0000-00908, XREWHT-L1-0000-00909, XREWHT-L1-0000-00910, and XREWHT-L1-0000-00937 are parametrically equivalent to the original part. These parts deliver identical optical output (84 lm at 350 mA), maintain identical package footprint and mounting characteristics, and provide improved thermal performance (8°C/W vs. 12°C/W).
Alternative with Extended Color Temperature Range: XREWHT-L1-0000-00901 offers the same optical and mechanical specifications with documented color temperature range of 5000K to 10000K and CRI of 75 (Typ). This part is suitable for applications requiring cool white LED performance with defined color rendering characteristics.
Neutral White Variants: XREWHT-L1-0000-009B1, XREWHT-L1-0000-009B2, and XREWHT-L1-0000-009B3 are neutral white variants maintaining identical electrical and optical specifications. These parts are appropriate for applications requiring neutral white color temperature.
All substitute parts are available in Tape & Reel (TR) packaging format and support the same MSL 4 handling requirements as the original component.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-00901 be used as a direct replacement for XRCWHT-L1-0000-00910?
A: Yes. Both parts deliver 84 lm at 350 mA test current, share identical 3529 package dimensions (9.00 mm × 7.00 mm), maintain 90° viewing angle, and are RoHS compliant with MSL 4 rating. The primary difference is forward voltage: XREWHT operates at 3.3V nominal versus 4.6V for the original part. Circuit designs must accommodate this 0.2V reduction. XREWHT-L1-0000-00901 additionally specifies color temperature range (5000K–10000K) and CRI (75 Typ).
Q: What is the difference between XREWHT-L1-0000-00910 and XREWHT-L1-0000-009B1?
A: Both parts are electrically and optically identical: 84 lm output, 3.3V forward voltage, 350 mA test current, 73 lm/W efficiency, identical package and thermal characteristics. The designation difference reflects internal binning or color temperature classification. XREWHT-L1-0000-009B1 is specified as neutral white, while XREWHT-L1-0000-00910 is specified as cool white. Both maintain identical performance parameters.
Q: Are all substitute parts available in the same packaging format?
A: All listed substitute parts are supplied in Tape & Reel (TR) format. The original XRCWHT-L1-0000-00910 was supplied in standard packaging; however, the XR-E series replacements standardize on TR packaging. Reel specifications and tape dimensions follow industry standard SMD packaging conventions for 3529 case components.
Q: What is the thermal performance improvement of XR-E versus XR-C?
A: The XR-E series provides 33% improved thermal resistance: 8°C/W compared to 12°C/W for the original XR-C part. This improvement reduces junction temperature rise under identical operating conditions and current levels, extending component lifetime and enabling higher reliability margins in thermal-constrained applications.
Q: Are there any electrical parameter differences that require circuit redesign?
A: Forward voltage differs by 0.2V: XR-E operates at 3.3V nominal versus 4.6V for XR-C. Current-limiting resistor values and power supply voltage margins must be recalculated. Maximum current rating increases from 500 mA to 1 A for XR-E parts, allowing higher brightness operation if required. Lumens/Watt efficiency improves from 69 to 73 lm/W, reducing power dissipation at equivalent brightness levels.
Q: Do all substitute parts maintain the same moisture sensitivity level?
A: Yes. All substitute parts carry MSL 4 rating (72 Hours maximum floor life), identical to the original component. Storage and handling procedures remain unchanged.
