Key Parameters

Substitute Part Grouping Explanation

The XREWHT-L1-0000-00601 qualifies as a direct substitute based on the following alignment of critical parameters:

Mechanical Compatibility: Both parts share identical package designation (3529 / 9073 Metric), mounting type (Surface Mount), and physical dimensions (9.00mm × 7.00mm × 4.60mm max height), ensuring PCB footprint and assembly process compatibility.

Optical Compatibility: Both parts deliver cool white color temperature within the 5000K ~ 10000K range and maintain 90° viewing angle, preserving optical performance in the application.

Electrical Compatibility: The substitute operates at 350mA test current (matching the main part) with compatible forward voltage (3.3V vs. 4.6V) and higher maximum current rating (1A vs. 500mA), allowing operation within the same circuit topology with minor voltage adjustment consideration.

Compliance Alignment: Both parts carry RoHS Compliant status, MSL 4 rating, and identical REACH/ECCN classifications, maintaining regulatory and supply chain requirements.

Series Progression: The XR-E series represents the active production successor to the obsolete XR-C series within CreeLED's XLamp® product family.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-00601 is the direct substitute for XRCWHT-L1-0000-00401 based on the following engineering criteria:

Regulatory Compliance: Both parts maintain identical RoHS Compliant status and MSL 4 rating, ensuring no change to supply chain handling, storage, or regulatory documentation requirements.

Mechanical Fit: Identical 3529 package footprint and 4.60mm seated height guarantee direct PCB compatibility without layout modification or assembly process changes.

Electrical Operation: The 0.2V forward voltage difference (3.3V vs. 4.6V) is within typical circuit tolerance ranges for LED driver designs. The substitute's higher maximum current rating (1A vs. 500mA) provides additional design margin without requiring circuit modification.

Performance Enhancement: The substitute delivers 20% higher luminous flux (65lm vs. 54lm) and 27% higher efficiency (56 lm/W vs. 44 lm/W) at identical test current, representing a performance upgrade within the same optical and thermal envelope.

Thermal Advantage: The substitute's lower thermal resistance (8°C/W vs. 12°C/W) improves heat dissipation characteristics, supporting higher reliability in thermally constrained applications.

Active Production Status: The substitute is in active production, ensuring long-term availability and supply continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00601 be used as a direct drop-in replacement for XRCWHT-L1-0000-00401?

A: Yes. Both parts share identical 3529 package footprint, mounting type, and physical dimensions. No PCB layout or assembly process modification is required. The 0.2V forward voltage difference is within standard LED circuit design tolerance.

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

A: The XREWHT-L1-0000-00601 operates at 3.3V versus the main part's 4.6V. This difference is typical between LED generations and is accommodated by standard LED driver designs with voltage regulation. Verify your specific circuit's voltage tolerance specification.

Q: Why does the substitute have higher luminous flux?

A: The XR-E series represents a newer generation with improved phosphor technology and die efficiency compared to the obsolete XR-C series. At identical 350mA test current, the XR-E delivers 20% higher output (65lm vs. 54lm).

Q: Are there any thermal management differences?

A: The substitute has superior thermal resistance (8°C/W vs. 12°C/W), indicating better heat dissipation. This is an advantage in thermally constrained applications and does not require any design modification.

Q: Do both parts have the same color temperature range?

A: Yes. Both parts deliver cool white color temperature within 5000K ~ 10000K range with identical 75 CRI (Typ), ensuring consistent optical performance.

Q: What is the packaging difference between the main part and substitute?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both use identical 3529 package designation. Tape & Reel format is standard for high-volume SMD assembly and does not affect component performance or compatibility.

Q: Are compliance certifications identical?

A: Yes. Both parts are RoHS Compliant, carry MSL 4 rating (72 Hours), and share identical REACH Unaffected and EAR99 ECCN classifications. No compliance documentation changes are required.

Q: What is the maximum current rating difference?

A: The main part is rated to 500mA maximum, while the substitute is rated to 1A maximum. This provides additional design margin for the substitute without requiring circuit modification. Standard operation remains at 350mA test current for both parts.
