Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-009E3 is determined by the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Color and CCT: White, Cool 5000K
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Viewing Angle: 90°
• CRI: 75 (Typ)
• Physical Dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)
• RoHS Compliance: RoHS Compliant
• MSL Rating: 4 (72 Hours)

Allowable Parameter Variations:

• Forward Voltage (Vf): 3.3V to 4.6V (within typical operating range)
• Test Current: 350mA (standard test condition)
• Maximum Current: 500mA to 1A (higher rating acceptable)
• Lumens/Watt: 69 to 73 lm/W (efficiency improvement acceptable)
• Thermal Resistance: 8°C/W to 12°C/W (lower resistance acceptable)
• Product Status: Active preferred over Obsolete
• Packaging Format: Bulk or Tape & Reel (TR) both acceptable

The two substitute parts listed (XREWHT-L1-0000-009E3 and XREWHT-L1-R250-009E3) meet all mandatory parameters and represent the XLamp® XR-E series evolution with improved electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (XREWHT-L1-0000-009E3 and XREWHT-L1-R250-009E3) are suitable replacements for the obsolete XRCWHT-L1-0000-009E3 based on the following engineering criteria:

Product Status: The substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete classification of the main part.

Compliance & Certifications: All three parts maintain identical RoHS Compliance, REACH Unaffected status, and MSL Rating (4, 72 Hours), ensuring regulatory and environmental compatibility.

Electrical Performance: The substitute parts operate at a lower typical forward voltage (3.3V vs. 4.6V) while maintaining identical luminous flux output (84lm at 350mA test current). The XLamp® XR-E series demonstrates improved efficiency (73 lm/W vs. 69 lm/W) and higher maximum current rating (1A vs. 500mA).

Thermal Characteristics: The substitute parts feature superior thermal resistance (8°C/W vs. 12°C/W), enabling better heat dissipation in thermal-constrained applications.

Mechanical Compatibility: Both substitute parts maintain identical package dimensions, height, viewing angle, and mounting type, ensuring direct PCB-level compatibility without layout modifications.

Packaging Consideration: The substitute parts are supplied in Tape & Reel (TR) format, standard for high-volume production environments. Bulk packaging availability should be confirmed with the supplier if required.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-009E3 and XREWHT-L1-R250-009E3 be used interchangeably?

A: Yes. Both substitute parts are electrically and mechanically identical. The difference lies in packaging format: XREWHT-L1-0000-009E3 is standard Tape & Reel, while XREWHT-L1-R250-009E3 is also Tape & Reel with a specific reel configuration. Selection depends on production equipment compatibility and supplier availability.

Q: What is the impact of the lower forward voltage (3.3V vs. 4.6V) on circuit design?

A: The 0.2V reduction in typical forward voltage is within normal operating tolerance for LED driver circuits. Existing current-limiting resistor or driver configurations will remain functional. Power consumption decreases slightly, improving overall system efficiency.

Q: Are the substitute parts pin-compatible with the original XRCWHT-L1-0000-009E3?

A: Yes. Both substitute parts use the identical 3529 (9073 Metric) package with matching physical dimensions (9.00mm x 7.00mm) and seated height (4.60mm). No PCB modifications are required.

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

A: The XLamp® XR-E series incorporates improved thermal design, reducing junction-to-case thermal resistance from 12°C/W to 8°C/W. This enhancement allows better heat transfer to the PCB and thermal management system, beneficial for high-current or thermally-constrained applications.

Q: Do the substitute parts maintain the same color temperature and CRI?

A: Yes. Both substitute parts maintain identical specifications: Cool White 5000K color temperature and 75 CRI (Typ). Color consistency is preserved across the substitution.

Q: What is the significance of the higher maximum current rating (1A vs. 500mA)?

A: The XLamp® XR-E series supports operation up to 1A, providing design flexibility for higher-brightness applications. Existing designs operating at 350mA test current are unaffected. The higher rating does not require circuit modifications for standard applications.

Q: Are moisture sensitivity levels identical?

A: Yes. All three parts carry MSL Rating 4 (72 Hours), requiring identical moisture control and handling procedures during storage, transportation, and assembly.
