Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-0000-000FE4 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain neutral white at 4500K to ensure color consistency in lighting applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be preserved.

Package and Mounting Type: Surface mount configuration with 2-SMD, Gull Wing form factor and identical footprint dimensions (5.00 mm × 5.00 mm) are required for PCB compatibility.

Thermal Resistance: The 5°C/W thermal resistance must be maintained to ensure equivalent thermal performance.

Moisture Sensitivity Level: MSL 2A classification must be matched for storage and handling requirements.

The MX6AWT-H1-0000-000DE4 qualifies as a substitute based on matching color, CCT, viewing angle, package footprint, height, thermal resistance, and MSL specifications. However, this substitute operates at significantly different electrical parameters (3.3V forward voltage, 300 mA test current) and is therefore suitable only for applications where the circuit design can accommodate these voltage and current differences.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DE4 is the identified substitute for the obsolete MX6SWT-H1-0000-000FE4. Selection of this substitute requires circuit-level evaluation due to fundamental differences in electrical operating parameters.

Voltage and Current Differences: The substitute operates at 3.3V forward voltage compared to the main part's 20V, with a test current of 300 mA versus 60 mA. These differences necessitate redesign of the LED driver circuit and current-limiting resistor networks. Direct pin-for-pin replacement without circuit modification will result in component failure or malfunction.

Compliance Status: The substitute part carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and identical MSL 2A classification.

Optical and Thermal Equivalence: Both parts deliver equivalent color performance (4500K, CRI 80, 120° viewing angle) and identical thermal resistance (5°C/W). The substitute achieves slightly higher efficiency (112 lm/W versus 105 lm/W) but delivers lower absolute flux (111 lm versus 126 lm) at its respective test current.

Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000DE4 be used as a direct replacement without circuit modification?

A: No. The substitute operates at 3.3V forward voltage and 300 mA test current, compared to the main part's 20V and 60 mA. Direct substitution without circuit redesign will damage the component. The LED driver and current-limiting circuit must be redesigned to accommodate the lower voltage and higher current requirements.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts share identical footprint dimensions (5.00 mm × 5.00 mm) and maximum seated height (1.48 mm). PCB layout compatibility is maintained. The substitute features an exposed pad variant of the 2-SMD Gull Wing package, which may provide improved thermal performance in applications utilizing the exposed pad for heat dissipation.

Q: What is the difference in light output between these parts?

A: At their respective test currents, the main part delivers 126 lumens while the substitute delivers 111 lumens. This 13% difference in absolute flux output must be considered in lighting design calculations. Both parts maintain identical color temperature (4500K) and color rendering index (CRI 80).

Q: Why is the main part classified as obsolete?

A: The MX6SWT-H1-0000-000FE4 belongs to the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series represented by the MX6AWT-H1-0000-000DE4. CreeLED has transitioned product lines, making the MX-6S series unavailable for new orders.

Q: Are there any compliance or certification differences?

A: The substitute is RoHS Compliant, while the main part does not specify RoHS status. Both parts are REACH Unaffected and carry identical MSL 2A moisture sensitivity classification. For applications requiring RoHS compliance, the substitute provides explicit certification.

Q: What is the thermal resistance specification, and why does it matter?

A: Both parts specify 5°C/W thermal resistance, indicating equivalent thermal performance. This parameter determines the temperature rise of the LED junction above ambient temperature at a given power dissipation level. Matching thermal resistance ensures consistent thermal behavior in the application circuit.
