Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following criteria:

• Package Compatibility: All substitutes use the same 3529 (9073 Metric) surface mount package with identical footprint dimensions (9.00mm x 7.00mm) and maximum seated height (4.60mm)
• Electrical Compatibility: All substitutes operate at 350mA test current with identical 65lm flux output at 25°C, ensuring equivalent light output in existing circuit designs
• Color Category: All substitutes maintain neutral white color classification with CCT values within the neutral white spectrum (4000K–4750K)
• Mechanical Compatibility: All substitutes feature 90° viewing angle and surface mount configuration
• Compliance: All substitutes maintain RoHS compliance and MSL 4 rating
• Series Transition: Substitutes transition from obsolete XLamp® XR-C to active XLamp® XR-E series, with improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA)

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts from the XLamp® XR-E series are active products with full RoHS compliance and equivalent MSL ratings. Selection among substitutes depends on CCT requirement:

• XREWHT-L1-0000-006F4 (4750K): Closest CCT match to the original XRCWHT-L1-0000-006F4 (4750K). Recommended for applications requiring identical color temperature.
• XREWHT-L1-0000-006E4 (4500K): Intermediate CCT option within neutral white spectrum.
• XREWHT-L1-0000-006F5 (4300K): Warmer neutral white option.
• XREWHT-L1-0000-006E5 (4000K): Coolest neutral white option.

All substitutes deliver identical 65lm flux output at 350mA test current and maintain identical package footprint and height. The XLamp® XR-E series provides improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current capability (700mA vs. 500mA), enabling enhanced design flexibility in thermal management and current headroom.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006F4 directly replace XRCWHT-L1-0000-006F4 on existing PCBs?

A: Yes. Both parts use identical 3529 (9073 Metric) surface mount package with matching footprint dimensions (9.00mm x 7.00mm) and seated height (4.60mm). No PCB layout modifications are required.

Q: What is the difference between XLamp® XR-C and XLamp® XR-E series?

A: The XLamp® XR-E series represents an active product line with improved thermal characteristics (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA). The XLamp® XR-C series is obsolete. Both series maintain identical package form factor and electrical test parameters at 350mA.

Q: How do I select the correct CCT among the substitute options?

A: CCT (Correlated Color Temperature) determines perceived color. 4750K (XREWHT-L1-0000-006F4) matches the original part. 4500K, 4300K, and 4000K options provide progressively warmer neutral white tones. Select based on application color temperature requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts carry RoHS Compliant status and maintain MSL 4 (72 Hours) moisture sensitivity rating, matching the original part's compliance profile.

Q: What is the impact of lower forward voltage (3.3V vs. 4.6V) in substitutes?

A: The 0.2V reduction in typical forward voltage (Vf) results in lower power dissipation at identical 350mA test current. This contributes to the improved thermal performance of the XLamp® XR-E series. Existing current-limiting circuit designs will operate within specification.

Q: Can I operate substitute parts at higher current than 350mA?

A: Yes. XLamp® XR-E substitutes support maximum current of 700mA (vs. 500mA for the original part), providing additional design margin. However, operation above 350mA test current may alter flux output and thermal characteristics. Consult detailed datasheets for performance at elevated currents.
