XMLEZW-02-0000-0B0HT635F LED EasyWhite™ Equivalent & Substitute Parts

Part Overview

The XMLEZW-02-0000-0B0HT635F is a CreeLED XLamp® XM-L warm white LED in 2020 (5050 metric) surface mount package, rated for 6V operation at 700mA with 290lm output at 85°C. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Substitute parts must maintain compatibility across electrical ratings, thermal characteristics, and mechanical form factor to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMLEZW-02-0000-0B0HT635F is determined by the following critical parameters:

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

Optical Characteristics: Color temperature (warm white 3500K) and Color Rendering Index (CRI ≥ 80) define the light quality requirements. MacAdam Ellipse specifications ensure chromaticity consistency.

Mechanical & Thermal: Package type (2020/5050 metric), surface mount configuration, and thermal resistance (2.5°C/W) determine physical and thermal compatibility. Height-seated maximum of 0.124" (3.15mm) constrains board-level integration.

Compliance & Status: RoHS compliance and MSL rating (1) are mandatory for production environments. Active product status is preferred for long-term supply assurance.

The XHP50B-00-0000-0D0UG235G meets these substitution criteria through shared package geometry, warm white color temperature, RoHS compliance, and dual-voltage operation capability at 6V/700mA.

Parameter Comparison

Engineering Selection Recommendations

The XHP50B-00-0000-0D0UG235G is the designated substitute for the obsolete XMLEZW-02-0000-0B0HT635F based on the following factors:

Product Status: The substitute part carries Active status, ensuring continued availability and supply chain stability compared to the obsolete main part.

Compliance Certifications: Both parts maintain RoHS compliance and EAR99 ECCN classification, satisfying regulatory requirements for production environments.

Electrical Compatibility: The substitute supports 6V operation at 700mA, matching the primary operating point of the original part. The XHP50B-00-0000-0D0UG235G provides additional 12V capability and higher maximum current ratings (3A at 6V), offering design flexibility without compromising 6V/700mA compatibility.

Optical Performance: The substitute delivers superior luminous efficacy (103 lm/W versus 69 lm/W) and higher CRI (90 versus 80) at the same 700mA test current, while maintaining warm white 3500K color temperature within acceptable MacAdam Ellipse tolerances.

Thermal Characteristics: The substitute exhibits improved thermal resistance (1.2°C/W versus 2.5°C/W), reducing junction temperature rise and extending operational life in thermally constrained applications.

Mechanical Fit: Both parts share identical 2020 (5050 metric) package footprint and surface mount configuration. The substitute height of 0.143" (3.63mm) versus 0.124" (3.15mm) represents a 0.019" (0.48mm) increase, which is within typical PCB assembly tolerances for most applications.

Frequently Asked Questions (FAQ)

Q: Can the XHP50B-00-0000-0D0UG235G directly replace the XMLEZW-02-0000-0B0HT635F in existing designs?

A: Yes, at the 6V/700mA operating point. Both parts share identical package footprint (2020/5050 metric), forward voltage (6V nominal), and test current (700mA). The substitute's 0.019" (0.48mm) height increase is within standard PCB assembly tolerances. Verify that board-level clearances accommodate the slightly taller package profile.

Q: What are the key differences between these parts?

A: The substitute (XHP50B) is an active product offering higher luminous efficacy (103 lm/W versus 69 lm/W), improved CRI (90 versus 80), lower thermal resistance (1.2°C/W versus 2.5°C/W), and dual-voltage capability (6V and 12V). The original (XMLEZW) is obsolete. Both maintain warm white 3500K color temperature and RoHS compliance.

Q: Are there any thermal design considerations when substituting?

A: The substitute's superior thermal resistance (1.2°C/W) reduces junction temperature rise compared to the original part (2.5°C/W). This improvement allows for higher ambient operating temperatures or reduced thermal management requirements. No additional cooling measures are necessary for equivalent or lower thermal loads.

Q: Does the substitute support the same maximum current rating?

A: At 6V operation, the substitute supports 3A maximum current versus 2A for the original part. At the standard 700mA test current, both parts operate within their respective safe operating areas. The substitute's higher current capability provides design margin without affecting 700mA compatibility.

Q: What is the impact of the MacAdam Ellipse difference (4-step versus 3-step)?

A: The original part specifies 4-step MacAdam Ellipse (tighter chromaticity tolerance), while the substitute specifies 3-step (broader tolerance). Both maintain 3500K warm white color temperature. The 3-step tolerance is acceptable for general lighting applications where color consistency within industry-standard ranges is required.

Q: Are moisture sensitivity levels equivalent?

A: The original part specifies MSL 1 (Unlimited). The substitute's MSL rating is not specified in the provided data. Consult the substitute part's detailed datasheet for MSL classification if moisture-sensitive storage or handling procedures are required in your production environment.

Q: Can the substitute be used in 12V applications?

A: Yes. The XHP50B-00-0000-0D0UG235G supports both 6V and 12V operation. At 12V, the part operates at 1.4A with a maximum rating of 1.5A. This dual-voltage capability enables broader design flexibility beyond the original part's 6V-only specification.
