Key Parameters

Substitute Part Grouping Explanation

The XREWHT-L1-0000-00801 qualifies as a parametric equivalent based on the following substitution criteria:

Matching Parameters:

• Color and CCT range: White, Cool 5000K ~ 10000K
• Flux output @ 25°C, 350mA: 77lm (74lm ~ 81lm)
• Test current: 350mA
• CRI: 75 (Typ)
• Viewing angle: 90°
• Package / Case: 3529 (9073 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)
• RoHS Status: RoHS Compliant
• MSL: 4 (72 Hours)

Allowable Variations:

• Forward voltage (Vf): 3.3V (substitute) vs. 4.6V (main part) — within acceptable tolerance for cool white LED applications
• Lumens/Watt: 67 lm/W (substitute) vs. 63 lm/W (main part) — improved efficiency
• Maximum current: 1A (substitute) vs. 500mA (main part) — higher rating provides design margin
• Thermal resistance: 8°C/W (substitute) vs. 12°C/W (main part) — improved thermal performance
• Product status: Active (substitute) vs. Obsolete (main part) — ensures ongoing availability

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-00801 is suitable for direct substitution of the obsolete XRCWHT-L1-0000-00801 in applications requiring cool white LED lighting at 5000K to 10000K color temperature. Both parts maintain identical optical output (77lm at 350mA), CRI (75 Typ), and mechanical compatibility within the 3529 surface mount package.

The substitute part offers engineering advantages: lower forward voltage (3.3V vs. 4.6V) reduces power dissipation, improved thermal resistance (8°C/W vs. 12°C/W) enhances thermal management, and higher maximum current rating (1A vs. 500mA) provides additional design margin. The active product status of the XR-E series ensures long-term component availability and supply chain continuity.

Both parts maintain RoHS compliance and identical moisture sensitivity levels (MSL 4, 72 Hours), supporting equivalent handling and storage requirements. No circuit redesign is required for substitution when operating at the specified 350mA test current.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00801 directly replace XRCWHT-L1-0000-00801 without circuit modification?

A: Yes. Both parts deliver identical luminous flux (77lm) at the standard 350mA test current, maintain the same color temperature range (5000K ~ 10000K), CRI (75 Typ), and occupy the same 3529 surface mount package with identical physical dimensions and height. The lower forward voltage of the substitute (3.3V vs. 4.6V) reduces power dissipation and improves efficiency without requiring circuit changes.

Q: What are the key differences between these parts?

A: The substitute XREWHT-L1-0000-00801 (XR-E series) differs from the main part XRCWHT-L1-0000-00801 (XR-C series) in forward voltage (3.3V vs. 4.6V), maximum current rating (1A vs. 500mA), thermal resistance (8°C/W vs. 12°C/W), lumens per watt efficiency (67 lm/W vs. 63 lm/W), and product status (Active vs. Obsolete). Optical and mechanical parameters remain identical.

Q: Are there packaging differences between these parts?

A: The main part XRCWHT-L1-0000-00801 is specified with packaging designation "-", while the substitute XREWHT-L1-0000-00801 is supplied in Tape & Reel (TR) format. Both use identical 3529 (9073 Metric) surface mount packages with matching physical dimensions (9.00mm x 7.00mm) and height (4.60mm max).

Q: Do both parts meet the same compliance standards?

A: Yes. Both XRCWHT-L1-0000-00801 and XREWHT-L1-0000-00801 are RoHS Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both maintain MSL 4 (72 Hours) moisture sensitivity levels, requiring identical handling and storage protocols.

Q: Why is the main part listed as obsolete?

A: The XRCWHT-L1-0000-00801 (XR-C series) has reached end-of-life status. CreeLED has transitioned to the XR-E series, represented by XREWHT-L1-0000-00801, which provides equivalent optical performance with improved thermal and electrical characteristics while maintaining active production status.
