Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalent (Same Generation Upgrade):

XMLBWT-00-0000-000PS50Z7 qualifies as a direct equivalent because it maintains identical electrical parameters within acceptable tolerances: same color temperature (3000K), same package (2020/5050), same mounting type (SMD), same viewing angle (125°), same maximum current (3A), and same thermal resistance (2.5°C/W). The forward voltage differs minimally (2.72V vs. 2.9V), and the part is active status, making it the preferred replacement for obsolete XMLAWT units.

Similar Substitutes (Different Color Temperature):

PSL0102WBEB1 and PSL0102WBEC1 are similar substitutes from ROHM Semiconductor. These parts share the same package (2020/5050), mounting type (SMD), and physical dimensions. However, they operate at 5000K (cool white) instead of 3000K (warm white), have different electrical characteristics (3.3V forward voltage, 120mA test current vs. 700mA), lower luminous flux (38lm and 30lm respectively), and different maximum current ratings (200mA). These substitutes are suitable only when color temperature shift from warm to cool white is acceptable in the application.

Engineering Selection Recommendations

For Direct Replacement (Recommended): Select XMLBWT-00-0000-000PS50Z7 when the XMLAWT-00-0000-000PS50Z7 reaches end-of-life. This part maintains identical color temperature (3000K warm white), electrical operating parameters (700mA test current, 3A maximum), package dimensions (2020/5050), and thermal characteristics (2.5°C/W). The XM-L2 generation offers improved luminous efficacy (89 lm/W vs. 87 lm/W) and active product status, ensuring long-term availability and supply chain stability. Both parts are RoHS compliant and suitable for equivalent circuit designs without modification.

For Alternative Applications (Conditional): PSL0102WBEB1 and PSL0102WBEC1 are suitable substitutes only when the application can accommodate a shift from warm white (3000K) to cool white (5000K) color temperature. These ROHM parts operate at significantly lower current levels (120mA test vs. 700mA) and deliver reduced luminous flux (30–38lm vs. 177lm). They are appropriate for low-power indicator applications or designs where cool white illumination is acceptable. Both are ROHS3 compliant but carry higher moisture sensitivity (MSL 3) compared to the XM-L series (MSL 1).

Compliance Considerations: All listed substitutes maintain RoHS compliance. The XMLBWT part preserves the MSL 1 rating of the original, while ROHM PSL0102 variants require MSL 3 handling (168-hour floor life). Thermal management differs: XLamp parts dissipate 2.5°C/W, while PSL0102 thermal resistance is not specified, requiring thermal analysis for high-power applications.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000PS50Z7 be used as a direct drop-in replacement for XMLAWT-00-0000-000PS50Z7?

A: Yes. Both parts share identical package (2020/5050), mounting type (SMD), color temperature (3000K), test current (700mA), maximum current (3A), viewing angle (125°), and thermal resistance (2.5°C/W). The forward voltage differs slightly (2.72V vs. 2.9V), which is within acceptable design tolerance for most LED driver circuits. The XMLBWT is active status, making it the recommended replacement.

Q: What are the key differences between the XLamp XM-L and XM-L2 series?

A: The XM-L2 (XMLBWT) offers improved luminous efficacy (89 lm/W vs. 87 lm/W) and active product status. Electrical and mechanical parameters remain compatible. The XM-L (XMLAWT) is obsolete, while XM-L2 ensures ongoing availability.

Q: Can PSL0102 parts replace the XLamp LEDs?

A: PSL0102WBEB1 and PSL0102WBEC1 share the same 2020 (5050 metric) package and SMD mounting, but differ significantly in electrical operation and color temperature. They operate at 5000K (cool white) instead of 3000K (warm white), require only 120mA test current versus 700mA, and deliver 30–38lm instead of 177lm. These substitutes are suitable only for applications where cool white color and lower power consumption are acceptable.

Q: What is the impact of different forward voltages on circuit design?

A: XMLAWT operates at 2.9V typical, while XMLBWT operates at 2.72V typical. This 0.18V difference is minor and typically accommodated by LED driver circuits with voltage regulation. PSL0102 parts operate at 3.3V, requiring circuit redesign for proper current limiting and voltage regulation.

Q: Are there moisture sensitivity concerns with these substitutes?

A: XMLAWT and XMLBWT carry MSL 1 (unlimited floor life), allowing indefinite storage without baking. PSL0102 parts carry MSL 3 (168-hour floor life), requiring baking after 168 hours of exposure to ambient humidity. This affects supply chain handling and storage protocols.

Q: What thermal management considerations apply to these parts?

A: XMLAWT and XMLBWT both specify 2.5°C/W thermal resistance, suitable for high-power applications with proper PCB thermal design. PSL0102 thermal resistance is not specified, limiting their use in high-power scenarios. Verify thermal performance through application-specific testing if using PSL0102 variants in power-critical designs.

Q: Are all substitutes RoHS compliant?

A: Yes. XMLAWT and XMLBWT are RoHS Compliant. PSL0102WBEB1 and PSL0102WBEC1 are ROHS3 Compliant. All parts meet RoHS requirements for new designs.
