Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMLEZW-02-0000-0D0HT635H is determined by the following critical parameters:

• Package / Case: Both parts must use 2020 (5050 Metric) surface mount package for PCB footprint compatibility
• Color & CCT: Warm white 3500K 2-Step MacAdam Ellipse specification must be maintained
• Mounting Type: Surface mount requirement is non-negotiable
• Voltage & Current Compatibility: Forward voltage and test current ratings must support the application circuit
• Viewing Angle: 115° minimum viewing angle requirement
• Thermal Characteristics: Thermal resistance and height-seated dimensions affect thermal management and board layout
• Compliance: RoHS compliance and MSL rating must be maintained

The XHP50B-00-0000-0D0UG235H qualifies as a substitute based on matching package, color specification, mounting type, and compliance certifications. However, electrical performance characteristics differ and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The XHP50B-00-0000-0D0UG235H is an active product substitute for the obsolete XMLEZW-02-0000-0D0HT635H. Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements for new designs.

Key considerations for selection:

• Product Status: The substitute is active, ensuring long-term availability and supply chain stability compared to the obsolete main part
• Compliance Certifications: Both parts carry identical RoHS and REACH compliance, maintaining regulatory alignment
• Electrical Performance: The substitute delivers higher luminous flux (810lm vs. 290lm), higher efficiency (103 lm/W vs. 69 lm/W), and improved CRI (90 vs. 80). These enhancements require circuit evaluation to ensure compatibility with existing current-limiting designs
• Thermal Performance: The substitute offers superior thermal resistance (1.2°C/W vs. 2.5°C/W), improving thermal management in high-density applications
• Physical Dimensions: Height difference of 0.019" (0.48mm) may require PCB layout verification in space-constrained designs
• Voltage Flexibility: The substitute supports both 6V and 12V operation, providing circuit design flexibility

Frequently Asked Questions (FAQ)

Q: Can the XHP50B-00-0000-0D0UG235H be used as a direct drop-in replacement for the XMLEZW-02-0000-0D0HT635H?

A: Both parts share the same 2020 (5050 metric) package and surface mount footprint, enabling physical compatibility. However, electrical performance differs significantly. The substitute delivers 2.8x higher luminous flux and operates at higher current levels. Circuit redesign may be necessary to accommodate these performance differences.

Q: What are the key differences in electrical specifications?

A: The substitute operates at higher current levels (1.4A or 700mA vs. 350mA test current) and delivers substantially higher luminous flux (810lm vs. 290lm). The substitute also supports dual voltage operation (6V or 12V) compared to the main part's 12V-only specification. Current-limiting circuits must be adjusted accordingly.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical RoHS compliance and REACH unaffected status. No regulatory barriers exist for substitution from a compliance perspective.

Q: How does the height difference affect PCB design?

A: The substitute is 0.019" (0.48mm) taller than the main part. In applications with tight vertical clearance constraints, PCB layout verification is necessary to confirm compatibility with enclosures or adjacent components.

Q: What is the impact of improved thermal resistance on system design?

A: The substitute's superior thermal resistance (1.2°C/W vs. 2.5°C/W) reduces junction temperature rise under identical power dissipation. This improvement enhances reliability in thermally constrained applications and may reduce cooling requirements.

Q: Does the substitute support the same viewing angle?

A: The substitute provides a slightly wider viewing angle (120° vs. 115°), which is compatible with or exceeds the main part's specification.
