XMLAWT-00-0000-000US40F8 Equivalent & Substitute Parts

Part Overview

The XMLAWT-00-0000-000US40F8 is a CreeLED XLamp® XM-L warm white LED (2850K) in 2020 (5050 Metric) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The XM-L series delivers 168 lm at 700mA test current with a forward voltage of 2.9V and 90 CRI, suitable for warm white lighting applications requiring high color rendering.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Color Temperature (CCT): Must match 2850K warm white specification
• Package / Case: Must be 2020 (5050 Metric) surface mount
• Forward Voltage (Vf): Acceptable range 2.72V–2.9V for direct substitution
• Test Current: 700mA nominal operation
• CRI (Color Rendering Index): Minimum 90 for warm white applications
• Mounting Type: Surface mount only
• Physical Dimensions: 5.00mm × 5.00mm footprint with maximum seated height 3.15mm

Direct Manufacturer Substitute: XMLBWT-00-0000-000US40F8 (CreeLED XM-L2 series) meets all critical parameters with identical CCT, package, and electrical characteristics within acceptable tolerance.

Similar Manufacturer Substitutes: PSL0102WBEB1 and PSL0102WBEC1 (ROHM Semiconductor PSL0102 series) share the same 2020 package and surface mount configuration but operate at different electrical parameters (120mA test current, 3.3V Vf, 5000K CCT). These are classified as similar rather than direct substitutes due to color temperature and current rating differences.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XMLBWT-00-0000-000US40F8 is the recommended direct substitute. Both parts are CreeLED XLamp® products with identical color temperature (2850K), CRI (90), package dimensions, and electrical operating parameters within acceptable tolerance. The XMLBWT is active product status, ensuring long-term availability and supply chain stability compared to the obsolete XMLAWT.

Alternative Substitutes: PSL0102WBEB1 and PSL0102WBEC1 are compatible at the mechanical and package level but require circuit redesign due to different electrical characteristics. These parts operate at 120mA test current versus 700mA, 3.3V forward voltage versus 2.9V, and 5000K color temperature versus 2850K. Selection of ROHM parts is appropriate only when warm white color temperature is not a critical requirement and cool white (5000K) is acceptable for the application. Both ROHM parts carry ROHS3 compliance and higher moisture sensitivity (MSL 3) compared to the CreeLED parts.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000US40F8 be used as a direct drop-in replacement for XMLAWT-00-0000-000US40F8?

A: Yes. Both parts share identical color temperature (2850K), CRI (90), package (2020 / 5050 Metric), forward voltage (2.9V typical for XMLAWT, 2.72V for XMLBWT), test current (700mA), and thermal characteristics (2.5°C/W). The XMLBWT is the next-generation XM-L2 variant with active product status.

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

A: PSL0102 parts are mechanically compatible (same 2020 package, surface mount) but electrically and optically different. They are classified as similar substitutes for applications where warm white color temperature is not mandatory. The 5000K cool white output and lower test current (120mA) require circuit redesign.

Q: What is the impact of different forward voltages between XMLAWT and XMLBWT?

A: The forward voltage difference (2.9V vs. 2.72V) is within acceptable tolerance for most LED driver circuits. The XMLBWT operates at slightly lower voltage, resulting in marginally lower power dissipation. Existing driver designs for XMLAWT will function with XMLBWT without modification.

Q: Are there height differences between CreeLED and ROHM parts?

A: Yes. CreeLED XM-L and XM-L2 parts have maximum seated height of 0.124" (3.15mm), while ROHM PSL0102 parts are significantly lower at 0.039" (1.00mm). This difference may affect PCB layout and thermal management considerations.

Q: What is the moisture sensitivity difference between these parts?

A: XMLAWT and XMLBWT carry MSL 1 (unlimited moisture exposure), while PSL0102 parts carry MSL 3 (168 hours maximum before reflow). This affects storage, handling, and production scheduling for ROHM components.

Q: Can I use PSL0102WBEC1 instead of PSL0102WBEB1?

A: Both are mechanically and electrically identical PSL0102 parts in the same 2020 package. The primary difference is CRI: PSL0102WBEC1 has CRI 90 versus PSL0102WBEB1 with CRI 80. Selection depends on color rendering requirements for the application.
