Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMLEZW-02-0000-0B0HT535F is determined by the following critical parameters:

Mechanical Compatibility: Package type (2020/5050 metric), mounting type (surface mount), and physical dimensions must match exactly to ensure PCB footprint compatibility without redesign.

Electrical Compatibility: Forward voltage (6V nominal), test current (700mA), and maximum current rating (2A) establish the operational envelope. Substitute parts must support 6V operation at 700mA minimum.

Optical Characteristics: Color temperature (warm white 3500K), MacAdam ellipse specification (4-step or tighter), and viewing angle (115° minimum) define the photometric performance window.

Thermal Performance: Thermal resistance of 2.5°C/W or lower ensures equivalent heat dissipation characteristics in the application circuit.

Compliance & Status: RoHS compliance and active product status are required for new designs and ongoing supply assurance.

The substitute part XHP50B-00-0000-0D0UG235G meets these criteria through identical package geometry, compatible voltage/current ratings at 700mA operation, matching color temperature specification, and active product status with improved thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The XHP50B-00-0000-0D0UG235G is the qualified substitute for XMLEZW-02-0000-0B0HT535F based on the following engineering criteria:

Compliance Alignment: Both components are RoHS compliant and manufactured by CreeLED, Inc., ensuring regulatory consistency and supply chain continuity.

Product Status: The substitute part maintains active product status, eliminating obsolescence risk and ensuring long-term availability for production and field replacement applications.

Electrical Equivalence: The substitute supports 6V operation at 700mA, matching the primary operating point of the original component. The higher maximum current rating (3A vs. 2A) and dual voltage support (6V/12V) provide design flexibility without compromising backward compatibility.

Mechanical Fit: Identical 2020 (5050 metric) package footprint and surface mount configuration enable direct PCB placement without layout modification. The 0.48mm height difference (3.63mm vs. 3.15mm) remains within standard PCB assembly tolerances for most applications.

Optical Performance: The 3500K warm white color temperature with 3-step MacAdam ellipse specification meets the original chromaticity requirement with tighter tolerance control. The improved CRI (90 vs. 80) provides enhanced color rendering capability.

Thermal Advantage: The 1.2°C/W thermal resistance represents a 52% improvement over the original 2.5°C/W specification, enabling better heat dissipation and extended operational life in thermally constrained applications.

Frequently Asked Questions (FAQ)

Q: Can XHP50B-00-0000-0D0UG235G be used as a direct drop-in replacement for XMLEZW-02-0000-0B0HT535F?

A: Yes, for applications operating at 6V and 700mA. The identical 2020 (5050 metric) package footprint and surface mount configuration enable direct PCB placement. The 0.48mm height difference is within standard assembly tolerances. Verify that the application circuit does not depend on the specific thermal resistance value or maximum current rating of the original component.

Q: What is the significance of the MacAdam ellipse specification difference (4-step vs. 3-step)?

A: The MacAdam ellipse defines the acceptable chromaticity tolerance around the target color point. A 3-step specification is tighter than 4-step, meaning the substitute part has more stringent color consistency control. This represents an improvement in color uniformity and is compatible with applications requiring the original 4-step specification.

Q: Does the higher lumens output of the substitute part affect circuit compatibility?

A: The higher output (810lm vs. 270lm) reflects improved LED efficiency in the XHP50.2 series. At the same 700mA test current, the substitute part delivers more light. If the application circuit is current-limited to 700mA, the forward voltage and electrical load remain equivalent. Verify that the application does not have brightness-dependent feedback or control mechanisms that could be affected by increased output.

Q: Is the height difference (3.63mm vs. 3.15mm) acceptable for my application?

A: The 0.48mm difference is within standard PCB assembly tolerances for surface mount components. Verify clearance with adjacent components, solder joint formation, and any mechanical constraints in the application enclosure. If height is critical, consult the PCB design documentation.

Q: What is the advantage of the improved thermal resistance (1.2°C/W vs. 2.5°C/W)?

A: Lower thermal resistance enables more efficient heat transfer from the LED junction to the PCB and surrounding environment. This reduces junction temperature at the same operating current, extending LED lifespan and maintaining color stability over extended operation. The improvement is particularly beneficial in thermally constrained applications or high-ambient-temperature environments.

Q: Are there any compliance or certification differences between the two parts?

A: Both components are RoHS compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.41.0000. No compliance differences exist. The substitute part's active product status ensures ongoing regulatory compliance and supply chain support.

Q: Can the substitute part operate at 12V as specified in its datasheet?

A: Yes, the XHP50B-00-0000-0D0UG235G supports both 6V and 12V operation. However, for direct replacement of the XMLEZW-02-0000-0B0HT535F, operate at 6V and 700mA to maintain electrical equivalence. 12V operation requires different circuit design and is not a direct substitute scenario.
