Substitute Part Grouping Explanation

Substitution eligibility for the XMLAWT-02-0000-000PS50Z7 is determined by the following criteria:

Color Temperature & CRI: Warm white (3000K) with CRI 85 minimum
Photometric Performance: Flux output 172–182 lm at 700mA test current
Electrical Compatibility: Forward voltage range 2.72–2.9V; maximum current 3A
Mechanical Compatibility: 2020 (5050 Metric) surface mount package; 3.15mm maximum seated height
Thermal Properties: 2.5°C/W thermal resistance
Regulatory Compliance: RoHS Compliant status

The XMLBWT-02-0000-000PS50Z7 meets all substitution criteria. Although it represents a newer generation (XM-L2 vs. XM-L), it maintains identical package geometry, thermal characteristics, color specification, and flux output range while offering improved efficiency and active product status.

Engineering Selection Recommendations

The XMLBWT-02-0000-000PS50Z7 is the direct substitute for the obsolete XMLAWT-02-0000-000PS50Z7. Selection is supported by:

Identical Mechanical Fit: Both parts use the 2020 (5050 Metric) package with 3.15mm maximum seated height, ensuring PCB layout compatibility without redesign.
Matching Photometric Specification: Both deliver 177 lm (172–182 lm range) at 700mA, maintaining luminous output consistency in existing designs.
Equivalent Thermal Performance: Identical 2.5°C/W thermal resistance ensures thermal management characteristics remain unchanged.
Regulatory Compliance: Both parts are RoHS Compliant, REACH Unaffected, and carry EAR99 ECCN classification.
Active Product Status: The substitute is actively manufactured, ensuring long-term availability and supply chain stability compared to the obsolete original.

The forward voltage reduction from 2.9V to 2.72V (0.18V decrease) represents improved efficiency in the XM-L2 generation and is within typical design tolerance for LED driver circuits. The efficiency improvement (87 to 89 lm/W) provides additional performance margin without requiring circuit modification.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-02-0000-000PS50Z7 be used as a direct replacement without PCB modification?

A: Yes. Both parts share identical 2020 (5050 Metric) package dimensions and 3.15mm maximum seated height. No PCB layout changes are required for mechanical compatibility.

Q: How does the forward voltage difference (2.9V vs. 2.72V) affect circuit operation?

A: The 0.18V reduction in forward voltage represents improved efficiency in the XM-L2 generation. Standard LED driver circuits designed for 2.9V operation will function with the 2.72V part, typically resulting in slightly reduced current draw at the same supply voltage. Verify driver specifications if operating near minimum voltage thresholds.

Q: Are the photometric outputs equivalent?

A: Yes. Both parts deliver 177 lm (172–182 lm range) at 700mA test current with identical 85 CRI and 125° viewing angle. Luminous output and color rendering are equivalent for lighting applications.

Q: What is the difference between XM-L and XM-L2 series?

A: The XM-L2 represents a newer generation with improved efficiency (89 vs. 87 lm/W) and lower forward voltage (2.72V vs. 2.9V). Both generations maintain identical package, thermal, and photometric specifications for this warm white 3000K configuration.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process; reel specifications may differ from the original part's packaging.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS Compliant, REACH Unaffected, and classified as EAR99. No compliance differences exist between the original and substitute.
