Substitute Part Grouping Explanation

Substitute parts for the XMLBWT-00-0000-000LT40F6 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (CreeLED XLamp® XM-L2 Series): Parts XMLBWT-00-0000-000LT40E6 and XMLBWT-00-0000-000LT40E7 share identical electrical specifications with the main part—forward voltage of 2.72V, test current of 700mA, maximum current of 3A, 125° viewing angle, and 2020 (5050 Metric) package dimensions. These parts differ only in color temperature (3500K and 3000K respectively), making them direct substitutes for applications where warm white color temperature variation is acceptable within the 3000K–3750K range.

Similar Parts (ROHM PSL0102 Series): Parts PSL0102WBEB1 and PSL0102WBEC1 share the same 2020 (5050 Metric) package footprint and surface mount compatibility. However, these parts operate at different electrical parameters—3.3V forward voltage, 120mA test current, and 200mA maximum current—and deliver lower luminous flux (30–38lm at 120mA). These are classified as similar rather than parametric equivalents due to significant differences in voltage, current, and flux specifications.

Engineering Selection Recommendations

For Direct Substitution (Parametric Equivalents): XMLBWT-00-0000-000LT40E6 and XMLBWT-00-0000-000LT40E7 are recommended as primary substitutes. Both maintain active product status, identical electrical performance at 2.72V forward voltage and 700mA test current, and full RoHS compliance. Selection between these parts depends on color temperature requirements: XMLBWT-00-0000-000LT40E6 at 3500K provides minimal color shift from the 3750K specification, while XMLBWT-00-0000-000LT40E7 at 3000K offers warmer tone for applications tolerating broader color temperature ranges.

For Alternative Applications (Similar Parts): PSL0102WBEB1 and PSL0102WBEC1 are classified as similar parts suitable only for applications with different electrical and optical requirements. These ROHM parts operate at 3.3V forward voltage and 120mA test current, delivering significantly lower flux output (30–38lm) compared to the main part (250lm). Both parts are marked obsolete and should be considered only when circuit design accommodates lower voltage and current specifications. PSL0102WBEC1 offers higher CRI (90 versus 80), which may be advantageous for color-critical applications despite lower luminous output.

Compliance Considerations: All substitute parts maintain RoHS compliance. The main part and parametric equivalents are RoHS Compliant; similar parts are ROHS3 Compliant. All parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000LT40E6 and XMLBWT-00-0000-000LT40E7 be used interchangeably with the main part?

A: Yes, within the constraints of color temperature tolerance. Both parts share identical electrical specifications (2.72V forward voltage, 700mA test current, 3A maximum current) and mechanical compatibility (2020 package, 3.15mm height, 125° viewing angle). The only difference is color temperature: 3500K for E6 and 3000K for E7 versus 3750K for the main part. Applications requiring strict color temperature matching should specify the exact part number.

Q: Why are PSL0102WBEB1 and PSL0102WBEC1 classified as similar rather than equivalent?

A: These ROHM parts operate at fundamentally different electrical parameters. They require 3.3V forward voltage (versus 2.72V) and operate at 120mA test current (versus 700mA), delivering 30–38lm flux output compared to 250lm from the main part. Circuit redesign is necessary to accommodate these differences. They are suitable only for applications with lower power and flux requirements.

Q: What is the impact of package height differences between the main part and ROHM alternatives?

A: The main part and CreeLED parametric equivalents have a seated height of 3.15mm, while ROHM PSL0102 parts are 1.00mm. This 2.15mm difference affects PCB layout, thermal management, and mechanical clearance. Applications with height constraints may benefit from the lower-profile ROHM parts, but electrical redesign is required.

Q: Are the ROHM PSL0102 parts suitable for direct replacement in existing designs?

A: No. PSL0102WBEB1 and PSL0102WBEC1 are obsolete products requiring circuit modification due to different voltage, current, and flux specifications. They should be considered only for new designs where electrical parameters can be accommodated.

Q: What is the significance of CRI differences among substitute parts?

A: The main part and all CreeLED parametric equivalents specify CRI of 80 (Typ). PSL0102WBEB1 also specifies CRI 80, while PSL0102WBEC1 specifies CRI 90. Higher CRI indicates better color rendering accuracy. For applications requiring enhanced color fidelity, PSL0102WBEC1 offers superior performance, though at the cost of lower luminous output and different electrical requirements.

Q: How do packaging differences (Tape & Reel versus Cut Tape) affect component selection?

A: The main part and CreeLED parametric equivalents are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. ROHM PSL0102 parts are supplied in Cut Tape (CT) packaging, requiring manual handling or alternative assembly processes. This affects procurement, inventory management, and production workflow.
