XRCWHT-L1-0000-00A03 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00A03 is a CreeLED XLamp® XR-C cool white LED (6000K) in 3529 surface mount package, rated for 350mA operation at 4.6V forward voltage. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which offers improved thermal performance and higher maximum current ratings while maintaining compatible package geometry and optical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00A03 is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts maintain identical package geometry (3529 / 9073 Metric), physical dimensions (9.00mm x 7.00mm), and mounting height (4.60mm maximum), ensuring direct PCB footprint compatibility.

Optical Compatibility: Substitute parts maintain the same viewing angle (90°), color category (White, Cool), and luminous flux output (91lm at 350mA test current). The CRI remains constant at 75 (Typ).

Electrical Compatibility: All substitutes operate at the same test current (350mA) and produce equivalent luminous output. Forward voltage differs slightly (3.3V vs. 4.6V), which is within acceptable design tolerance for LED applications using current-limiting circuits.

Color Temperature Variants: Two CCT options are available—6000K (matching the original) and 5000K (alternative cool white). Selection depends on application requirements.

Packaging Format: Substitutes are supplied in Tape & Reel (TR) format, whereas the original part number does not specify packaging. Both formats are compatible with standard pick-and-place assembly equipment.

Series Upgrade: The XLamp® XR-E series substitutes offer improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (1A vs. 500mA), providing enhanced performance headroom for thermal management and current handling.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products from CreeLED, Inc., ensuring long-term availability and supply chain stability compared to the obsolete XRCWHT-L1-0000-00A03. All substitutes maintain RoHS compliance and identical MSL ratings, supporting equivalent manufacturing and storage requirements.

For 6000K Color Temperature Requirement: Select either XREWHT-L1-0000-00A03 or XREWHT-L1-R250-00A03. Both deliver 6000K CCT with identical optical and electrical performance. The R250 variant indicates a specific reel configuration; selection depends on procurement and assembly line specifications.

For 5000K Color Temperature Requirement: Select either XREWHT-L1-0000-00AE3 or XREWHT-L1-R250-00AE3. Both deliver 5000K CCT with identical performance characteristics to their 6000K counterparts.

Thermal Performance Advantage: All XLamp® XR-E substitutes provide 33% improved thermal resistance (8°C/W vs. 12°C/W), reducing junction temperature rise and extending LED lifetime in thermally constrained applications.

Electrical Headroom: The XLamp® XR-E series supports 1A maximum current versus 500mA for the original part, providing design flexibility for future performance scaling without component replacement.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00A03 be used as a direct replacement for XRCWHT-L1-0000-00A03?

A: Yes. Both parts share identical package geometry (3529), physical dimensions (9.00mm x 7.00mm), mounting height (4.60mm), viewing angle (90°), and luminous output (91lm at 350mA). The 0.2V forward voltage difference (3.3V vs. 4.6V) is accommodated by standard LED current-limiting circuit design and does not affect compatibility.

Q: What is the difference between the R250 and non-R250 part numbers?

A: The R250 designation indicates a specific reel configuration for tape-and-reel packaging. Both variants (XREWHT-L1-0000-00A03 and XREWHT-L1-R250-00A03) are electrically and optically identical. Selection depends on assembly equipment compatibility and procurement specifications.

Q: Should I select 6000K or 5000K?

A: Selection depends on application requirements. The original XRCWHT-L1-0000-00A03 operates at 6000K (cool white). If color temperature consistency is required, select XREWHT-L1-0000-00A03 or XREWHT-L1-R250-00A03 (both 6000K). The 5000K variants (XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3) are suitable only if application design permits cooler white color temperature.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts carry RoHS Compliant certification, matching the original part's compliance status.

Q: What is the inventory status of substitute parts?

A: XREWHT-L1-0000-00A03: 856 pcs; XREWHT-L1-0000-00AE3: 892 pcs; XREWHT-L1-R250-00A03: 850 pcs; XREWHT-L1-R250-00AE3: 1100 pcs. All are in stock as new original components.

Q: Does the improved thermal resistance (8°C/W vs. 12°C/W) require circuit design changes?

A: No. The lower thermal resistance of XLamp® XR-E substitutes provides improved thermal performance without requiring circuit modifications. Existing current-limiting designs remain valid.
