Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00601 is determined by the following critical parameters:

Electrical Compatibility:

• Color and CCT range (White, Cool, 5000K ~ 10000K)
• Luminous flux at 25°C and 350mA test current (65lm nominal)
• Forward voltage operating range (4.6V nominal for XR-C series)
• CRI specification (75 Typ)

Mechanical Compatibility:

• Package type (3529 / 9073 Metric)
• Physical dimensions (9.00mm x 7.00mm footprint, 4.60mm max height)
• Mounting type (Surface Mount)
• Viewing angle (90°)

Regulatory & Environmental:

• RoHS Compliance
• REACH Status
• MSL rating (4, 72 Hours)

The XREWHT-L1-0000-00601 (XLamp® XR-E series) qualifies as a parametric equivalent based on matching color, CCT range, luminous flux output, package dimensions, mounting type, and regulatory compliance. While the XR-E variant operates at a lower typical forward voltage (3.3V vs. 4.6V) and exhibits improved thermal characteristics (8°C/W vs. 12°C/W), these differences remain within acceptable substitution parameters for the specified electrical and mechanical requirements.

Engineering Selection Recommendations

The XREWHT-L1-0000-00601 is the qualified substitute for the obsolete XRCWHT-L1-0000-00601. Selection is supported by the following factors:

Product Status: The substitute part maintains Active status, ensuring ongoing availability and supply chain continuity compared to the Obsolete main part.

Regulatory Compliance: Both components are RoHS Compliant and REACH Unaffected, maintaining equivalent environmental and regulatory standing.

Electrical Performance: Identical luminous flux output (65lm at 25°C, 350mA), color specification (White, Cool, 5000K ~ 10000K), and CRI rating (75 Typ) ensure functional equivalence in lighting applications.

Mechanical Compatibility: Identical package type (3529 / 9073 Metric), footprint dimensions (9.00mm x 7.00mm), and mounting height (4.60mm max) provide direct PCB compatibility without layout modifications.

Thermal Characteristics: The substitute exhibits superior thermal performance (8°C/W vs. 12°C/W), reducing thermal management requirements in the application circuit.

Electrical Differences: The substitute operates at a lower typical forward voltage (3.3V vs. 4.6V) and supports higher maximum current (1A vs. 500mA). Circuit designs must accommodate the 0.2V forward voltage reduction through appropriate current-limiting resistor or driver adjustments.

Frequently Asked Questions (FAQ)

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

A: The XREWHT-L1-0000-00601 is mechanically and functionally compatible for the same 3529 package footprint and luminous flux output. However, the forward voltage difference (3.3V vs. 4.6V) requires circuit adjustment. Current-limiting resistor values or LED driver settings must be recalculated to maintain the 350mA test current specification.

Q: What are the key differences between the XR-C and XR-E series?

A: The primary differences are forward voltage (4.6V for XR-C vs. 3.3V for XR-E), maximum current rating (500mA vs. 1A), thermal resistance (12°C/W vs. 8°C/W), and lumens per watt efficiency (53 lm/W vs. 56 lm/W). Both series share identical color, CCT range, CRI, package type, and physical dimensions.

Q: Does the lower forward voltage of the XR-E series affect brightness?

A: No. Both components deliver identical luminous flux (65lm at 25°C, 350mA test current) and CRI (75 Typ). The lower forward voltage reflects improved LED die efficiency in the XR-E series, not reduced light output.

Q: Are there any packaging differences between these parts?

A: The main part (XRCWHT-L1-0000-00601) is supplied in standard packaging, while the substitute (XREWHT-L1-0000-00601) is supplied in Tape & Reel (TR) format. Both use the identical 3529 (9073 Metric) component package with matching footprint and height specifications.

Q: What circuit modifications are required to use the XREWHT-L1-0000-00601 as a substitute?

A: The 0.2V forward voltage reduction requires recalculation of series current-limiting resistor values or LED driver output voltage settings to maintain the desired operating current. The substitute's higher maximum current rating (1A) provides additional design margin. Thermal management may be simplified due to improved thermal resistance (8°C/W).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the XRCWHT-L1-0000-00601 and XREWHT-L1-0000-00601 are RoHS Compliant and REACH Unaffected, maintaining equivalent regulatory status.

Q: What is the MSL rating for these components?

A: Both components carry an MSL rating of 4 (72 Hours), indicating identical moisture sensitivity and requiring equivalent storage and handling precautions.
