XMLAWT-00-0000-000HT40F6 Equivalent & Substitute Parts

Part Overview

The XMLAWT-00-0000-000HT40F6 is a Cree XLamp® XM-L warm white LED (3750K) in 2020 (5050 Metric) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The XM-L series delivers 250lm at 700mA test current with 123 lm/W efficiency and 80 CRI, suitable for warm white lighting applications requiring high luminous output in compact form factors.

Substitute Part Grouping Explanation

Substitution for the XMLAWT-00-0000-000HT40F6 is determined by the following criteria:

Direct Equivalent (Same Manufacturer, Same Series Evolution):

• XMLBWT-00-0000-000HT40F6 (XLamp® XM-L2 successor) qualifies as a direct substitute based on identical color temperature (3750K), matching package (2020/5050 Metric), identical viewing angle (125°), identical thermal resistance (2.5°C/W), matching test current (700mA), and equivalent luminous output (250lm at 85°C test condition). The XM-L2 represents the active product line evolution of the obsolete XM-L series.

Similar Substitutes (Different Manufacturer, Different Series):

• PSL0102WBEB1 and PSL0102WBEC1 (ROHM Semiconductor PSL0102 series) are classified as similar substitutes. These parts share the same package footprint (2020/5050 Metric), surface mount mounting type, and identical physical dimensions (5.00mm x 5.00mm). However, they differ in color temperature (5000K cool white vs. 3750K warm white), luminous output (30-38lm vs. 250lm), test current (120mA vs. 700mA), forward voltage (3.3V vs. 2.9V), and thermal characteristics. These parts are suitable only for applications where warm white color temperature is not a critical requirement and lower luminous output is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: XMLBWT-00-0000-000HT40F6

The XMLBWT-00-0000-000HT40F6 is the preferred direct substitute for the obsolete XMLAWT-00-0000-000HT40F6. Both parts are manufactured by CreeLED, Inc., maintain identical color temperature (3750K), package footprint (2020/5050 Metric), and luminous output specifications (250lm). The XMLBWT represents the active product line continuation of the XM-L series as the XM-L2 generation. Forward voltage is slightly lower (2.72V vs. 2.9V), which may reduce power dissipation in driver circuits. The XMLBWT-00-0000-000HT40F6 carries active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

Secondary Consideration: PSL0102WBEB1 and PSL0102WBEC1

The ROHM PSL0102 series parts are suitable only for applications where color temperature flexibility exists. These parts operate at 5000K (cool white) rather than 3750K (warm white), deliver significantly lower luminous output (30-38lm vs. 250lm), and require substantially lower drive current (120mA vs. 700mA). The PSL0102 series is appropriate for indicator lighting, status displays, or low-brightness applications where warm white color temperature is not required. Both PSL0102 variants are obsolete; PSL0102WBEC1 offers higher CRI (90 vs. 80) if color rendering is a secondary consideration.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000HT40F6 be used as a direct drop-in replacement for XMLAWT-00-0000-000HT40F6?

A: Yes. Both parts share identical package footprint (2020/5050 Metric), color temperature (3750K), luminous output (250lm), test current (700mA), viewing angle (125°), and thermal resistance (2.5°C/W). The forward voltage difference (2.72V vs. 2.9V) is within typical design tolerance for LED driver circuits. No circuit redesign is required.

Q: Why are PSL0102 parts listed as substitutes if they have different color temperature?

A: PSL0102 parts are classified as similar substitutes based on shared package footprint and surface mount compatibility. However, the 5000K color temperature (cool white) differs from the 3750K warm white specification of the XMLAWT. These parts are suitable only for applications where warm white color temperature is not a functional requirement.

Q: What is the significance of the height difference between XLamp XM-L and PSL0102 parts?

A: The XMLAWT and XMLBWT have maximum seated height of 3.15mm, while PSL0102 parts are 1.00mm maximum. This 2.15mm difference may affect PCB layout clearance, thermal management design, and optical system integration. Applications with tight vertical space constraints may benefit from the lower PSL0102 profile, but luminous output and color temperature must be re-evaluated.

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

A: XMLAWT and XMLBWT are RoHS Compliant. PSL0102 parts are ROHS3 Compliant. All parts are REACH Unaffected and carry EAR99 ECCN classification. MSL differs: XMLAWT is MSL 1 (Unlimited), while PSL0102 parts are MSL 3 (168 Hours), requiring controlled storage and handling.

Q: What is the impact of lower luminous output in PSL0102 parts?

A: PSL0102 parts deliver 30-38lm compared to 250lm for XMLAWT/XMLBWT. This represents an 85-88% reduction in light output. Applications requiring full brightness replacement must use XMLBWT. PSL0102 is suitable only for low-brightness indicator or accent lighting where reduced output is acceptable.
