Engineering Selection Recommendations
All listed substitute parts are active production components from CreeLED's XLamp® XR-E series, ensuring long-term availability and supply chain stability. Each substitute maintains identical mechanical compatibility through the 3529 (9073 Metric) package specification and 90° viewing angle configuration.
The XLamp® XR-E series substitutes provide improved thermal performance (8°C/W thermal resistance versus 12°C/W in the obsolete XR-C series), resulting in lower junction temperatures during operation and extended component lifespan. Efficiency gains of 3–9 lm/W across the substitute range support reduced power consumption in lighting applications.
Forward voltage reduction from 4.6V to 3.3V in XR-E substitutes requires circuit verification to confirm compatibility with existing current-limiting resistor networks and power supply specifications. The 0.2V differential is within typical design margins for most LED driver circuits but must be validated for applications with tight voltage tolerances.
All substitute parts maintain RoHS compliance and REACH unaffected status, meeting regulatory requirements for EU and international markets. Moisture sensitivity level remains constant at MSL 4 (72 Hours), preserving existing component handling and storage protocols.
Selection between neutral white (007B1–007B4) and warm white (007B5–007B9) variants depends on application color temperature requirements. The cool white variant (XREWHT-L1-0000-00801) offers higher luminous flux (77 lm) at the cost of increased forward voltage (3.3V) and efficiency (67 lm/W), suitable for applications requiring maximum brightness output.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-007B1 directly replace XRCWHT-L1-0000-00707 on existing PCBs?
A: Yes. Both components use the 3529 (9073 Metric) package with identical footprint dimensions (0.354" L × 0.276" W, 9.00 mm × 7.00 mm) and maximum seated height (0.181", 4.60 mm). No PCB layout modifications are required. However, circuit validation is necessary to confirm compatibility with the 0.2V lower forward voltage (3.3V vs. 4.6V).
Q: What is the difference between neutral white and warm white variants?
A: The provided data does not specify correlated color temperature (CCT) values for neutral white (007B1–007B4) or warm white (007B5–007B9) variants. Selection should be based on application-specific color temperature requirements. The cool white variant (XREWHT-L1-0000-00801) specifies 5000K–10000K CCT range.
Q: Are there current rating differences between the main part and substitutes?
A: The XRCWHT-L1-0000-00707 (main part) has a maximum current rating of 500 mA. Most XR-E substitutes do not specify maximum current in the provided data. XREWHT-L1-0000-00801 specifies 1 A maximum current, providing higher current headroom. Designs operating at 350 mA test current are compatible across all parts.
Q: How does thermal resistance affect component selection?
A: The XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to 12°C/W in the obsolete XR-C series. Lower thermal resistance reduces junction temperature rise during operation, improving reliability and light output stability. This represents a 33% improvement in thermal performance.
Q: Do all substitutes maintain the same luminous flux output?
A: Most XR-E substitutes (007B1–007B9) maintain 71 lm flux at 350 mA, matching the main part specification. XREWHT-L1-0000-00801 provides higher flux output at 77 lm, suitable for applications requiring increased brightness. Flux tolerance ranges (67–74 lm and 74–81 lm respectively) must be considered for brightness-critical applications.
Q: What packaging format is available for these substitutes?
A: All listed XLamp® XR-E substitutes are supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly. The XRCWHT-L1-0000-00707 main part does not specify packaging format in the provided data.
