XMLAWT-00-0000-000PS50F8 LED XLamp® XM-L Warm White 2850K Equivalent & Substitute Parts

Part Overview

The XMLAWT-00-0000-000PS50F8 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 design support and procurement. The XM-L series delivers 177 lm at 700 mA test current with a forward voltage of 2.9V and 87 lm/W efficiency. Substitution is driven by product lifecycle discontinuation and the need for functionally compatible alternatives that maintain thermal, optical, and electrical performance within acceptable design tolerances.

Substitute Part Grouping Explanation

Substitution for the XMLAWT-00-0000-000PS50F8 is evaluated using the following criteria:

Primary Substitution Criteria:

• Color temperature (CCT): 2850K warm white
• Package / Case: 2020 (5050 Metric) surface mount
• Mounting type: Surface mount
• Thermal resistance: 2.5°C/W
• Flux output range: 172–182 lm at test current
• Forward voltage tolerance: ±0.2V acceptable for circuit design
• CRI: ≥80 acceptable for warm white applications
• RoHS compliance: Required

Direct Manufacturer Substitute: XMLBWT-00-0000-000PS50F8 (CreeLED XLamp® XM-L2) meets all primary criteria. It is the generational successor within the same manufacturer's product line, maintaining identical package geometry, thermal characteristics, and warm white color temperature. The XM-L2 variant shows improved efficiency (89 lm/W vs. 87 lm/W) and lower forward voltage (2.72V vs. 2.9V), with flux output at 85°C matching the original part's 25°C specification.

Similar Manufacturer Substitutes: PSL0102WBEB1 and PSL0102WBEC1 (ROHM Semiconductor PSL0102 series) share identical package geometry and surface mount configuration. However, these parts operate at 5000K (cool white) rather than 2850K (warm white), represent a different manufacturer platform, and operate at significantly lower current (120 mA vs. 700 mA). These are classified as similar rather than direct substitutes due to color temperature and current rating differences.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended): XMLBWT-00-0000-000PS50F8 is the primary substitute. It is manufactured by CreeLED (same OEM as the original part), maintains active product status, and preserves all critical electrical and thermal parameters. The XM-L2 generation offers improved efficiency and lower forward voltage, reducing power dissipation in existing circuit designs. Both parts carry RoHS compliance and identical package geometry, enabling direct PCB footprint compatibility without design modification.

For Alternative Consideration: PSL0102WBEB1 and PSL0102WBEC1 are functionally compatible only in applications where color temperature shift from 2850K (warm white) to 5000K (cool white) is acceptable. These ROHM parts operate at 120 mA (not 700 mA) and deliver significantly lower flux output (30–38 lm vs. 177 lm). They are suitable only for low-power indicator or accent lighting applications, not for primary illumination requiring the original part's lumen output. Both ROHM parts carry ROHS3 compliance and MSL 3 (168 hours), requiring controlled moisture handling during storage and assembly.

Compliance Considerations: All substitute parts maintain RoHS compliance. The direct substitute (XMLBWT) carries MSL 1 (unlimited moisture sensitivity level), matching the original part's storage requirements. The ROHM alternatives require MSL 3 handling, imposing stricter moisture control during procurement, storage, and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000PS50F8 be used as a direct drop-in replacement for XMLAWT-00-0000-000PS50F8? A: Yes. Both parts share identical package geometry (2020/5050 metric), thermal resistance (2.5°C/W), forward voltage tolerance (2.9V vs. 2.72V is within typical circuit design margins), and warm white color temperature (2850K). The XM-L2 variant offers improved efficiency. No PCB redesign is required.

Q: Why are PSL0102 parts listed as substitutes if they operate at different current and color temperature? A: PSL0102 parts are classified as similar substitutes based on shared package geometry and surface mount configuration. However, they are not direct replacements. The 5000K color temperature (cool white vs. warm white) and 120 mA operating current (vs. 700 mA) make them suitable only for applications where these differences are acceptable. They deliver 30–38 lm output, insufficient for applications requiring the original part's 177 lm flux.

Q: What is the impact of forward voltage difference between XMLAWT (2.9V) and XMLBWT (2.72V)? A: The 0.18V difference is within typical design tolerance for LED driver circuits. The lower forward voltage of XMLBWT reduces power dissipation (P = I × V), resulting in lower thermal load and improved efficiency. Existing current-regulated driver circuits will operate without modification.

Q: Are there moisture sensitivity differences between the main part and substitutes? A: Yes. XMLAWT and XMLBWT carry MSL 1 (unlimited moisture sensitivity), requiring standard handling. PSL0102 parts carry MSL 3 (168 hours), requiring controlled humidity storage (≤60% RH) and bake-out procedures before assembly. This impacts procurement, inventory management, and assembly process control.

Q: Can PSL0102 parts be used in high-brightness applications? A: No. PSL0102 parts deliver 30–38 lm at 120 mA, compared to 177 lm at 700 mA for the original part. They are designed for indicator and accent lighting only. Applications requiring 177 lm output must use XMLBWT-00-0000-000PS50F8 or equivalent high-brightness alternatives.

Q: What is the CRI difference between warm white (2850K) and cool white (5000K) substitutes? A: The original part and XMLBWT substitute both deliver CRI 85 at 2850K (warm white), suitable for residential and hospitality lighting. PSL0102WBEB1 delivers CRI 80 at 5000K (cool white), while PSL0102WBEC1 delivers CRI 90 at 5000K. Color temperature and CRI are independent parameters; substitution requires matching both for consistent color rendering in the final application.

Q: Is XMLBWT available in the same packaging format as XMLAWT? A: XMLBWT is supplied in Tape & Reel (TR) format, while XMLAWT packaging format is not specified in the data. Both use identical component geometry and are compatible with standard pick-and-place assembly equipment. Verify packaging format compatibility with your procurement and assembly processes.
