Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMLEZW-02-0000-0D0HT640H is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: 2020 (5050 Metric) surface mount form factor
• Color: White, Neutral
• CCT (K): 4000K 2-Step MacAdam Ellipse
• Mounting Type: Surface Mount
• RoHS Compliance: RoHS Compliant

Operational Parameters:

• Voltage - Forward (Vf): 12V operation capability
• Current rating: Must support the application's current requirements
• Thermal characteristics: Package thermal resistance and height constraints

The XHP50B-00-0000-0D0UG440H qualifies as a substitute based on matching the mandatory criteria above while offering enhanced performance characteristics in flux output, efficiency, and CRI rating. Both parts share identical package dimensions and mounting specifications, enabling direct mechanical and electrical substitution in 2020 (5050 metric) surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

The XHP50B-00-0000-0D0UG440H is an active product substitute for the obsolete XMLEZW-02-0000-0D0HT640H. Both components are RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The substitute part maintains compatibility with the original 2020 (5050 metric) surface mount package footprint and supports 12V operation. The XHP50B-00-0000-0D0UG440H offers superior performance metrics including higher luminous flux (870lm versus 290lm), improved efficiency (111 lm/W versus 69 lm/W), and enhanced color rendering (CRI 90 versus CRI 80). The substitute part's maximum height of 0.143" (3.63mm) represents a 0.019" (0.48mm) increase over the original part, which must be evaluated against specific PCB assembly clearance requirements.

The substitute part's lower thermal resistance (1.2°C/W versus 2.5°C/W) provides improved thermal performance in high-current applications. Selection between the 700mA and 1.4A test current ratings of the substitute part should be based on the specific application's power budget and thermal management capabilities.

Frequently Asked Questions (FAQ)

Q: Can the XHP50B-00-0000-0D0UG440H be used as a direct replacement for the XMLEZW-02-0000-0D0HT640H?

A: Yes, for applications requiring 12V operation at 350mA or lower. Both parts share the 2020 (5050 metric) surface mount package, identical footprint dimensions (5.00mm x 5.00mm), and matching color temperature (4000K neutral white). The substitute part's increased height (0.143" versus 0.124") must be verified against PCB assembly clearance constraints.

Q: What are the key differences between these two parts?

A: The primary differences are product status (active versus obsolete), luminous flux output (870lm versus 290lm), efficiency (111 lm/W versus 69 lm/W), CRI rating (90 versus 80), and thermal resistance (1.2°C/W versus 2.5°C/W). The substitute part supports dual voltage operation (6V and 12V) with higher current ratings.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. No compliance differences exist between the two components.

Q: What is the impact of the height difference on PCB assembly?

A: The substitute part is 0.019" (0.48mm) taller than the original. This must be evaluated against specific PCB design clearances, solder reflow profiles, and any height-constrained applications.

Q: Can the substitute part operate at the original part's 350mA current rating?

A: Yes. The XHP50B-00-0000-0D0UG440H supports operation at 700mA and 1.4A test currents, with a maximum current rating of 1.5A at 12V. Operation at 350mA is within the part's rated specifications.

Q: What is the thermal performance improvement of the substitute part?

A: The substitute part's thermal resistance of 1.2°C/W is approximately 52% lower than the original part's 2.5°C/W, resulting in improved heat dissipation and lower junction temperatures under equivalent power dissipation conditions.
