Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mechanical Compatibility: All substitute parts maintain identical package type (3529/9073 metric), mounting configuration (surface mount), physical dimensions (9.00 mm × 7.00 mm), and seated height (4.60 mm).

Electrical Compatibility: Substitute parts operate within compatible voltage and current ranges. The main part operates at 4.6 V typical forward voltage with 350 mA test current and 500 mA maximum current. Substitutes operate at 3.3 V typical forward voltage with 350 mA test current and higher maximum current ratings (700 mA or unspecified), ensuring safe operation in circuits designed for the original part.

Optical Performance: All substitutes deliver 59 lm (57–62 lm range) at 350 mA test current, matching the main part's luminous flux specification. Viewing angle remains constant at 90° across all parts.

Regulatory Compliance: All parts maintain RoHS compliance, REACH unaffected status, and MSL 4 classification.

Series Transition: The main part belongs to the XLamp® XR-C series (obsolete). All substitutes belong to the XLamp® XR-E series (active product status), representing the current generation equivalent.

Engineering Selection Recommendations

All listed substitute parts are active products from CreeLED's XLamp® XR-E series and maintain full RoHS compliance and REACH unaffected status. The substitutes are organized into two functional groups:

Group 1: Cool White Specification (XREWHT-L1-0000-00601) This part specifies cool white color temperature (5000K–10000K) with CRI 75 typical. It delivers 65 lm at 350 mA test current, exceeding the main part's 59 lm specification. Forward voltage is 3.3 V with maximum current rating of 1 A. Thermal resistance is improved to 8°C/W.

Group 2: Neutral White Specification (XREWHT-L1-0000-005B6, XREWHT-L1-0000-005B7, XREWHT-L1-0000-005B8, XREWHT-L1-0000-005B9, XREWHT-L1-R250-005B6, XREWHT-L1-R250-005B7, XREWHT-L1-R250-005B8, XREWHT-L1-R250-005B9) These parts deliver 59 lm at 350 mA test current, matching the main part's luminous flux exactly. Forward voltage is 3.3 V. Parts without the R250 designation specify 700 mA maximum current; parts with R250 designation do not specify maximum current. All maintain 8°C/W thermal resistance.

Selection between groups depends on application color temperature requirements. Within Group 2, parts are functionally equivalent; selection may be based on packaging preference (tape and reel standard vs. R250 variant) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00601 be used as a direct replacement for XRCWHT-L1-0000-00507? A: Yes. Both parts share identical mechanical compatibility (3529 package, 90° viewing angle, 4.60 mm seated height), operate at compatible voltage and current levels (3.3 V vs. 4.6 V forward voltage, 350 mA test current), and deliver equivalent luminous flux (65 lm vs. 59 lm). The XREWHT part is an active product with improved thermal characteristics (8°C/W vs. 12°C/W).

Q: What is the difference between XREWHT-L1-0000-005B6 and XREWHT-L1-R250-005B6? A: Both parts are electrically and optically identical. The R250 designation indicates a packaging variant. Selection between these parts depends on supply chain requirements and packaging specifications for your manufacturing process.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts maintain RoHS compliance and REACH unaffected status, matching the regulatory profile of the main part.

Q: What is the impact of the 3.3 V forward voltage on circuits designed for 4.6 V? A: The 0.2 V reduction in forward voltage is within typical circuit design margins for LED applications. Circuits designed for the 4.6 V part will operate safely with 3.3 V substitutes. Current limiting resistors or drivers will automatically compensate for the voltage difference.

Q: Do the substitute parts maintain the same thermal characteristics? A: No. Substitute parts feature improved thermal resistance (8°C/W) compared to the main part (12°C/W). This represents a thermal performance improvement and does not create compatibility issues.

Q: Can I mix parts from Group 1 and Group 2 in the same application? A: Group 1 (XREWHT-L1-0000-00601) specifies cool white color temperature (5000K–10000K). Group 2 parts do not specify color temperature. If color temperature consistency is required across the application, maintain parts within the same group.

Q: What is the inventory status of these substitute parts? A: All substitute parts are listed as active products with current inventory availability ranging from 697 to 1,167 pieces.
