XRCWHT-L1-0000-00B03 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00B03 is a CreeLED XLamp® XR-C cool white LED (6000K) in 3529 surface mount package, rated for 350mA operation at 4.6V forward voltage with 90° viewing angle. This part is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The XLamp® XR-C series has been superseded by the active XLamp® XR-E series, which maintains compatible electrical and mechanical specifications while offering improved thermal performance and higher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 the XRCWHT-L1-0000-00B03 is determined by the following critical parameters:

Electrical Compatibility:

• Color and CCT (6000K cool white)
• Luminous flux at test current (97lm nominal)
• CRI rating (75 Typ)
• Viewing angle (90°)
• Test current (350mA)

Mechanical Compatibility:

• Package type (3529 / 9073 Metric)
• Physical dimensions (9.00mm x 7.00mm footprint, 4.60mm max height)
• Surface mount configuration

Operational Compatibility:

• Forward voltage tolerance (3.3V to 4.6V acceptable for 350mA operation)
• Maximum current rating (500mA minimum required)

All four substitute parts (XREWHT-L1-0000-00B03, XREWHT-L1-0000-00BE3, XREWHT-L1-R250-00B03, XREWHT-L1-R250-00BE3) meet these criteria. The primary differences are CCT variants (6000K vs. 5000K) and packaging format (standard vs. 2SMD configuration with reel marking R250).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using XRCWHT-L1-0000-00B03, transition to active XLamp® XR-E equivalents is required due to obsolescence status. All four substitute parts maintain identical mechanical compatibility and luminous output at the 350mA test current.

For 6000K CCT requirement: Select either XREWHT-L1-0000-00B03 or XREWHT-L1-R250-00B03. Both deliver 6000K color temperature with 97lm nominal flux. The R250 variant includes reel marking for automated assembly tracking.

For 5000K CCT requirement: Select either XREWHT-L1-0000-00BE3 or XREWHT-L1-R250-00BE3. Both deliver 5000K color temperature with identical 97lm nominal flux and thermal characteristics.

Thermal Performance Improvement: All XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to 12°C/W for the obsolete XR-C, resulting in lower junction temperatures under identical operating conditions.

Forward Voltage Consideration: XLamp® XR-E parts operate at 3.3V typical versus 4.6V for the XR-C. Existing current-limiting circuits designed for 4.6V will deliver slightly higher current through the 3.3V parts at the same supply voltage. Verify circuit design accommodates the 1A maximum current rating of XR-E devices.

Compliance: All substitute parts maintain RoHS compliance, REACH unaffected status, and MSL 4 rating identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00B03 directly replace XRCWHT-L1-0000-00B03 without circuit modification?

A: Direct mechanical and thermal substitution is possible. However, the 0.2V lower forward voltage (3.3V vs. 4.6V) may increase current draw in constant-voltage circuits. Verify your current-limiting design accommodates operation within the 1A maximum rating of the XR-E series.

Q: What is the difference between XREWHT-L1-0000-00B03 and XREWHT-L1-R250-00B03?

A: Both parts are electrically and mechanically identical. The R250 designation indicates reel marking for automated pick-and-place equipment tracking. Select based on your assembly process requirements.

Q: Why do the 5000K variants (00BE3) exist as substitutes for a 6000K part?

A: The 5000K variants are listed as available substitutes within the XLamp® XR-E family. Selection depends on your application's color temperature requirement. If 6000K is specified, use the 00B03 variants. If 5000K is acceptable, the 00BE3 variants are available.

Q: Are the physical dimensions identical between XR-C and XR-E?

A: Yes. Both series use the 3529 (9073 Metric) package with 9.00mm x 7.00mm footprint and 4.60mm maximum seated height. PCB layout and reflow profiles remain compatible.

Q: What is the impact of improved thermal resistance (8°C/W vs. 12°C/W)?

A: Lower thermal resistance reduces junction temperature rise for the same power dissipation. At 350mA operation, this results in approximately 1.4°C lower junction temperature, improving reliability and light output stability over the device lifetime.

Q: Are all substitute parts currently in stock?

A: Inventory status at time of reference: XREWHT-L1-0000-00B03 (957 pcs), XREWHT-L1-0000-00BE3 (1018 pcs), XREWHT-L1-R250-00B03 (919 pcs), XREWHT-L1-R250-00BE3 (926 pcs). Verify current availability with your supplier.

Q: Do all parts meet the same compliance standards?

A: Yes. All substitute parts are RoHS compliant, REACH unaffected, and carry MSL 4 (72 Hours) rating identical to the main part. ECCN and HTSUS classifications are consistent across the family.
