Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-00A01 is based on the following critical parameters that must remain constant or compatible:

• Color Temperature (CCT): 5000K ~ 10000K (cool white range must be maintained)
• Luminous Flux @ 25°C: 91 lm nominal (87 ~ 94 lm range acceptable)
• Test Current: 350 mA operation point
• Viewing Angle: 90° (wide angle requirement)
• Package / Case: 3529 (9073 Metric) surface mount form factor
• Mounting Type: Surface Mount (SMD)
• CRI: 75 Typ (color rendering consistency)
• Compliance: RoHS Compliant, REACH Unaffected

The substitute parts XREWHT-L1-0000-00A01 and XREWHT-L1-R250-00A01 are from the XLamp® XR-E series and meet all critical substitution criteria. Both parts maintain identical color temperature, flux output, test current, viewing angle, package dimensions, and compliance certifications. The primary differences are forward voltage (3.3V vs 4.6V) and maximum current rating (1A vs 500mA), which represent improvements in the XR-E design.

Parameter Comparison

Engineering Selection Recommendations

Both XREWHT-L1-0000-00A01 and XREWHT-L1-R250-00A01 are direct substitutes for XRCWHT-L1-0000-00A01 based on the following engineering criteria:

Product Status: The substitute parts carry Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete XRCWHT-L1-0000-00A01.

Compliance & Certifications: All three parts maintain identical RoHS Compliance, REACH Unaffected status, and Moisture Sensitivity Level (MSL 4, 72 Hours), ensuring regulatory and environmental compliance requirements are preserved.

Electrical Compatibility: The substitute parts operate at the same test current (350 mA) and deliver identical luminous flux (91 lm) at 25°C. The lower forward voltage (3.3V vs 4.6V) in the XR-E series represents a design improvement that reduces power dissipation. The increased maximum current rating (1A vs 500mA) provides additional operational margin without affecting the 350 mA test point performance.

Mechanical Compatibility: Package dimensions, mounting type, and form factor are identical across all three parts, enabling direct PCB-level substitution without layout modifications.

Thermal Performance: The XR-E substitute parts offer improved thermal resistance (8°C/W vs 12°C/W), resulting in lower junction temperatures during operation.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00A01 and XREWHT-L1-R250-00A01 be used interchangeably with XRCWHT-L1-0000-00A01?

A: Yes. Both substitute parts maintain identical color temperature range (5000K ~ 10000K), luminous flux output (91 lm @ 25°C), test current (350 mA), viewing angle (90°), and package dimensions (3529 / 9073 Metric). Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What is the difference between XREWHT-L1-0000-00A01 and XREWHT-L1-R250-00A01?

A: Both parts are electrically and mechanically identical. The difference lies in packaging: XREWHT-L1-0000-00A01 is supplied in standard Tape & Reel (TR) format, while XREWHT-L1-R250-00A01 is also supplied in Tape & Reel (TR) format. Both are Active products with identical performance specifications and are suitable for direct substitution.

Q: Why is the forward voltage different (4.6V vs 3.3V)?

A: The XLamp® XR-E series represents a newer generation design with improved efficiency. The lower forward voltage (3.3V) reduces power dissipation while maintaining identical luminous flux output at the 350 mA test current. This is an engineering improvement that does not affect substitution compatibility.

Q: Are there any thermal considerations when substituting these parts?

A: The substitute parts offer improved thermal resistance (8°C/W vs 12°C/W), resulting in lower junction temperatures. This improvement enhances reliability and does not introduce thermal compatibility issues. Existing thermal management designs will continue to function correctly.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL 4, 72 Hours). Regulatory and environmental compliance is maintained across all substitutions.

Q: Can I use these parts in existing PCB designs without modification?

A: Yes. The 3529 (9073 Metric) surface mount package dimensions and mounting type are identical. Direct PCB-level substitution is possible without layout or footprint changes.
