Engineering Selection Recommendations
All listed substitute parts are classified as Active products, ensuring long-term availability and manufacturing support. The XLamp® XR-E series represents the current generation replacement for the obsolete XLamp® XR-C series.
Primary Substitutes (Parametric Equivalents): XREWHT-L1-0000-00A05, XREWHT-L1-0000-00A07, XREWHT-L1-0000-00A08, XREWHT-L1-0000-00A09, XREWHT-L1-0000-00A10, and XREWHT-L1-0000-00A37 are direct parametric equivalents. These parts maintain identical luminous flux (91 lm at 350 mA), viewing angle (90°), and mechanical footprint. The forward voltage reduction from 4.6V to 3.3V results in improved efficiency (79 lm/W versus 74 lm/W) and reduced thermal resistance (8°C/W versus 12°C/W).
Alternative with Enhanced Performance: XREWHT-L1-0000-00B01 offers higher luminous flux (97 lm at 350 mA) and superior efficiency (84 lm/W). This part includes a defined color temperature range (5000K–10000K cool white) and CRI specification (75 Typ). It is suitable for applications where increased brightness and color consistency are beneficial.
Neutral White Variants: XREWHT-L1-0000-00AB1, XREWHT-L1-0000-00AB2, and XREWHT-L1-0000-00AB3 are neutral white variants maintaining identical electrical and mechanical specifications as the cool white parametric equivalents. These are appropriate for applications requiring neutral white color temperature.
All substitute parts maintain RoHS compliance, REACH unaffected status, and MSL 4 (72 Hours) rating, ensuring regulatory and environmental compatibility with the original design.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-00A08 directly replace XRCWHT-L1-0000-00A08 in existing designs?
A: Yes. Both parts share identical mechanical footprint (3529 package, 9.00 mm × 7.00 mm), height (4.60 mm), viewing angle (90°), and luminous flux specification (91 lm at 350 mA). The forward voltage difference (3.3V versus 4.6V) is within acceptable tolerance for most circuit designs and improves efficiency.
Q: What is the difference between the cool white XREWHT-L1-0000-00B01 and the parametric equivalents?
A: XREWHT-L1-0000-00B01 delivers higher luminous flux (97 lm versus 91 lm at 350 mA) and includes a defined color temperature range (5000K–10000K) with CRI specification (75 Typ). Use this part when increased brightness or color consistency is required. All other electrical and mechanical parameters remain compatible.
Q: Are neutral white variants (XREWHT-L1-0000-00AB1, AB2, AB3) electrically equivalent to cool white variants?
A: Yes. Neutral white variants maintain identical electrical specifications (3.3V forward voltage, 350 mA test current, 91 lm flux) and mechanical compatibility. The difference is color temperature classification. Select based on application color temperature requirements.
Q: What is the impact of the thermal resistance improvement from 12°C/W to 8°C/W?
A: The reduced thermal resistance in XLamp® XR-E substitutes results in lower junction temperature at equivalent drive current, extending LED lifespan and improving reliability. This is a performance improvement requiring no circuit modification.
Q: Are all substitute parts RoHS compliant and REACH unaffected?
A: Yes. All substitute parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory compatibility with the original XRCWHT-L1-0000-00A08 design.
Q: What is the MSL rating for all substitute parts?
A: All substitute parts carry MSL 4 (72 Hours) rating, identical to the original part. Standard moisture control procedures during storage and handling apply.
Q: Can I use XREWHT-L1-0000-00B01 in applications designed for 91 lm output?
A: XREWHT-L1-0000-00B01 produces 97 lm at 350 mA, exceeding the 91 lm specification. This part is suitable for applications where increased brightness is acceptable or beneficial. For designs requiring exact 91 lm output, use parametric equivalents (XREWHT-L1-0000-00A05, A07, A08, A09, A10, or A37).
