XREWHT-L1-0000-006F4 Equivalent & Substitute Parts

Part Overview

The XREWHT-L1-0000-006F4 is a Cree XLamp® XR-E series LED designed for neutral white lighting applications at 4750K color temperature. This surface mount device operates at 3.3V with a 350mA test current and delivers 65 lumens at 25°C. The component is actively produced and RoHS compliant, making it suitable for current production designs. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the XLamp® XR-E product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the XLamp® XR-E series is determined by strict equivalence in the following parameters:

• Voltage - Forward (Vf): 3.3V
• Current - Test: 350mA
• Current - Max: 700mA
• Flux @ 25°C: 65lm (62lm ~ 67lm range)
• Lumens/Watt: 56 lm/W
• CRI: 75 (Typ)
• Viewing Angle: 90°
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Thermal Resistance: 8°C/W

The substitute part XREWHT-L1-0000-006E5 maintains identical electrical performance and mechanical compatibility. The only variation is the CCT (Color Correlated Temperature), which differs from 4750K to 4000K. This parameter difference does not affect electrical substitutability but represents a distinct product variant within the same performance class.

Parameter Comparison

Engineering Selection Recommendations

Both the XREWHT-L1-0000-006F4 and XREWHT-L1-0000-006E5 are active production components with identical RoHS compliance and REACH unaffected status. Selection between these parts is determined by application-specific color temperature requirements. The XREWHT-L1-0000-006F4 operates at 4750K (warmer neutral white), while the XREWHT-L1-0000-006E5 operates at 4000K (cooler neutral white). All other electrical, thermal, and mechanical parameters are equivalent. Both components carry MSL 4 rating and require controlled storage conditions. Component selection should be based on the specific CCT requirement of the end application, as all other performance characteristics are identical.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006E5 be used as a direct replacement for XREWHT-L1-0000-006F4?

A: Electrical and mechanical substitution is valid. Both parts share identical voltage, current, flux output, efficiency, CRI, viewing angle, package dimensions, and thermal characteristics. The difference is color temperature: 4750K versus 4000K. Substitution is appropriate only if the application can accommodate the cooler color temperature of 4000K.

Q: Are there any thermal or power dissipation differences between these parts?

A: No. Both parts operate at identical forward voltage (3.3V), test current (350mA), maximum current (700mA), and thermal resistance (8°C/W). Thermal management requirements are equivalent.

Q: Do both parts use the same package and mounting footprint?

A: Yes. Both use the 3529 (9073 Metric) package with identical dimensions of 0.354" L x 0.276" W (9.00mm x 7.00mm) and maximum seated height of 0.181" (4.60mm). PCB footprints and reflow profiles are compatible.

Q: What is the significance of the CCT difference between 4750K and 4000K?

A: CCT (Color Correlated Temperature) defines the perceived color of the light output. 4750K produces a warmer neutral white appearance, while 4000K produces a cooler neutral white appearance. This is a visual characteristic only and does not affect electrical performance or component compatibility.

Q: Are both parts RoHS compliant and suitable for current production?

A: Yes. Both XREWHT-L1-0000-006F4 and XREWHT-L1-0000-006E5 are active production components with RoHS compliance and REACH unaffected status. Both carry MSL 4 rating requiring controlled storage at 72 hours maximum exposure.
