XRCWHT-L1-0000-005F4 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-005F4 is a CreeLED XLamp® XR-C neutral white LED (4750K) in 3529 SMD package, rated for 350mA operation at 4.6V forward voltage. This part is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which maintains compatible electrical and mechanical specifications while offering improved thermal performance and higher maximum current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-005F4 is based on the following criteria:

Mandatory Compatibility Parameters:

• Color: White, Neutral (maintained across all substitutes)
• Package / Case: 3529 (9073 Metric) (identical footprint and mounting)
• Viewing Angle: 90° (maintained across all substitutes)
• Mounting Type: Surface Mount (maintained across all substitutes)
• CRI: 75 (Typ) (maintained across all substitutes)
• Flux @ 25°C, 350mA: 59lm (57lm ~ 62lm) (maintained across all substitutes)
• Current - Test: 350mA (maintained across all substitutes)

Allowable Variation Parameters:

• CCT (K): Neutral white range (4300K to 4750K acceptable for neutral white applications)
• Voltage - Forward (Vf): 3.3V to 4.6V (within typical forward voltage tolerance for white LEDs)
• Lumens/Watt: 48 to 51 lm/W (improved efficiency in substitutes)
• Current - Max: 500mA to 700mA (higher maximum rating in substitutes)
• Thermal Resistance: 8°C/W to 12°C/W (improved thermal performance in substitutes)
• Series: XLamp® XR-C to XLamp® XR-E (generational upgrade within same product family)

All substitute parts are from CreeLED, Inc., maintain RoHS compliance, and carry identical MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products from CreeLED, Inc., and maintain full RoHS compliance and identical MSL ratings to the obsolete XRCWHT-L1-0000-005F4. The XLamp® XR-E series substitutes offer improved thermal performance (8°C/W versus 12°C/W) and higher maximum current ratings (700mA versus 500mA), enabling greater design flexibility for thermal management and current headroom.

XREWHT-L1-0000-005F4 provides the closest CCT match at 4750K, maintaining identical color temperature to the original part while delivering the performance improvements of the XR-E series.

XREWHT-L1-0000-005E4 operates at 4500K, suitable for applications where a slightly warmer neutral white is acceptable within the neutral white spectrum.

XREWHT-L1-0000-005F5 operates at 4300K, appropriate for applications requiring the warmest end of the neutral white range.

All substitutes maintain identical flux output (59lm at 350mA), viewing angle (90°), package footprint (3529), and CRI (75) as the original part. Forward voltage reduction from 4.6V to 3.3V in the XR-E series may require minor circuit adjustments in current-limiting designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005F4 be used as a direct replacement for XRCWHT-L1-0000-005F4?

A: Yes. Both parts operate at 4750K CCT, deliver 59lm at 350mA test current, maintain 90° viewing angle, and use identical 3529 SMD package. The primary differences are series designation (XR-E versus XR-C), forward voltage (3.3V versus 4.6V), and improved thermal resistance (8°C/W versus 12°C/W). Circuit designs using current-limiting resistors may require adjustment due to the 0.2V forward voltage difference.

Q: What is the difference between the three substitute parts?

A: The three XLamp® XR-E substitutes differ only in CCT: XREWHT-L1-0000-005E4 at 4500K, XREWHT-L1-0000-005F4 at 4750K, and XREWHT-L1-0000-005F5 at 4300K. All other electrical and mechanical parameters are identical. Selection depends on the required color temperature for the application.

Q: Are the substitute parts pin-compatible with the original XRCWHT-L1-0000-005F4?

A: Yes. All parts use the identical 3529 (9073 Metric) SMD package with matching footprint dimensions (9.00mm x 7.00mm) and seated height (4.60mm maximum). PCB layout and reflow profiles remain unchanged.

Q: What is the impact of the forward voltage difference (4.6V to 3.3V)?

A: The 0.2V reduction in forward voltage affects current-limiting circuit calculations. In resistive current-limiting designs, the reduced forward voltage results in slightly higher LED current at the same supply voltage. Designs using active current regulation (constant current drivers) are unaffected. Verify circuit performance during qualification.

Q: Do the substitute parts have the same thermal characteristics?

A: The XLamp® XR-E substitutes offer improved thermal performance with 8°C/W thermal resistance compared to 12°C/W for the original XR-C part. This improvement allows higher sustained current operation and better thermal management in compact designs.

Q: Are all parts RoHS compliant and available in the same packaging options?

A: Yes. All parts are RoHS compliant with identical MSL ratings (4, 72 Hours). The substitute parts are available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the maximum current rating for each part?

A: The original XRCWHT-L1-0000-005F4 is rated for 500mA maximum. All three XLamp® XR-E substitutes are rated for 700mA maximum, providing additional current headroom for higher brightness applications.
