XRCWHT-L1-0000-005F5 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-005F5 is a CreeLED XLamp® XR-C neutral white LED (4300K) in 3529 surface mount package. This part is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. The XLamp® XR-C series has been superseded by newer generations within the XLamp® product line, requiring engineers to evaluate parametric equivalents for design continuity.

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005F5 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must maintain neutral white at 4300K for color consistency in lighting applications.
• Photometric Output: Flux at 25°C and 350mA test current must remain within the specified range (57lm ~ 62lm) to preserve luminous intensity.
• Electrical Characteristics: Forward voltage, test current, and maximum current ratings must be compatible with existing circuit designs.
• Optical Properties: Viewing angle (90°) and CRI (75 Typ) must be maintained for application requirements.
• Physical Compatibility: Package type (3529), mounting type (Surface Mount), and dimensional envelope must match PCB layouts.
• Thermal Performance: Thermal resistance rating affects heat dissipation capability in the application.
• Regulatory Compliance: RoHS and REACH status must be maintained for supply chain and end-market requirements.

The XREWHT-L1-0000-005F5 (XLamp® XR-E series) meets these substitution criteria as an active product with equivalent optical and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-005F5 is the qualified substitute for the obsolete XRCWHT-L1-0000-005F5. Selection is based on:

• Active Product Status: The XLamp® XR-E variant is in active production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain RoHS Compliant and REACH Unaffected status, meeting regulatory requirements for the target market.
• Photometric Equivalence: Identical flux output (59lm at 350mA) and CRI (75 Typ) ensure color and brightness consistency in end applications.
• Electrical Compatibility: Forward voltage difference (3.3V vs 4.6V) is within typical circuit tolerance ranges for LED driver designs. The higher maximum current rating (700mA vs 500mA) provides additional operational margin.
• Thermal Improvement: Lower thermal resistance (8°C/W vs 12°C/W) offers superior heat dissipation performance.
• Physical Interchangeability: Identical package, footprint, and mounting characteristics enable direct PCB substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-005F5 be used as a direct replacement for the XRCWHT-L1-0000-005F5?

A: Yes. Both parts share identical photometric output (59lm at 350mA), color temperature (4300K), CRI (75), viewing angle (90°), and physical package (3529). The forward voltage difference (3.3V vs 4.6V) is within standard LED driver tolerance and does not prevent direct substitution.

Q: What is the impact of the 0.2V forward voltage difference?

A: The XREWHT-L1-0000-005F5 operates at 3.3V versus 4.6V for the original part. This 0.2V reduction typically results in lower power consumption and reduced thermal load. Most LED driver circuits accommodate this variation through current regulation, requiring no circuit redesign.

Q: Why is the thermal resistance lower in the substitute part?

A: The XLamp® XR-E series (8°C/W) demonstrates improved thermal performance compared to the XR-C series (12°C/W). This enhancement reduces junction temperature at equivalent power levels, extending LED lifespan and improving reliability.

Q: Are there packaging differences between these parts?

A: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. Both use identical 3529 surface mount packages with matching footprints and mounting characteristics. Tape & Reel packaging is standard for automated assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the XRCWHT-L1-0000-005F5 and XREWHT-L1-0000-005F5 are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for EU and international markets.

Q: What is the maximum current rating difference, and does it matter?

A: The substitute part supports 700mA maximum current versus 500mA for the original. This higher rating provides additional operational headroom and does not affect substitution compatibility when operated at the standard 350mA test current.
