Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000G51 is determined by the following critical parameters:

Color Temperature & Photometric Performance: Both the main part and substitute must maintain 6500K cool white color temperature with CRI of 75 (Typ) to ensure consistent color rendering in the application.

Mechanical Compatibility: The 5.00mm x 5.00mm footprint and 1.48mm maximum seated height establish the physical constraints for PCB layout and assembly. The 2-SMD, Gull Wing package configuration must be preserved for reflow soldering compatibility.

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

Thermal & Environmental Compliance: Thermal resistance of 5°C/W and MSL 2A (4 Weeks) establish the thermal and moisture handling requirements. REACH Unaffected status confirms regulatory compliance.

Electrical Operation: While forward voltage and test current differ between the main part and substitute, the substitute must operate within the same general application class (surface mount LED lighting). The substitute's active product status and RoHS compliance provide advantages over the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000E51 is a direct substitute for the obsolete MX6SWT-A1-0000-000G51 based on the following factors:

Product Status & Availability: The substitute is active and currently in stock (726 Pcs), whereas the main part is obsolete. This ensures long-term supply chain continuity and future availability.

Regulatory Compliance: The substitute carries explicit RoHS Compliant certification, providing enhanced environmental and regulatory compliance compared to the main part. Both parts maintain REACH Unaffected status.

Photometric Equivalence: Both parts deliver 6500K cool white color temperature with 75 CRI (Typ) and 120° viewing angle, ensuring consistent color rendering and optical performance in the application.

Mechanical Compatibility: Identical footprint (5.00mm x 5.00mm), seated height (1.48mm), and thermal resistance (5°C/W) confirm direct PCB compatibility. The exposed pad variant in the substitute provides improved thermal management.

Electrical Differences: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA. Circuit design must accommodate this voltage and current difference. The substitute delivers 119 lm/W efficiency versus 113 lm/W, representing a performance improvement.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000E51 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000G51?

A: Mechanical and optical compatibility is confirmed (identical footprint, height, viewing angle, color temperature, and CRI). However, the electrical operating parameters differ significantly: the substitute requires 3.3V forward voltage and 300mA test current versus the main part's 20V and 60mA. Circuit redesign is necessary to accommodate these electrical differences.

Q: What are the key parameters that determine substitutability?

A: Color temperature (6500K), CRI (75 Typ), viewing angle (120°), footprint (5.00mm x 5.00mm), seated height (1.48mm), thermal resistance (5°C/W), and MSL rating (2A, 4 Weeks) are the primary parameters that establish substitution eligibility. Electrical parameters (forward voltage and current) differ and require circuit adaptation.

Q: Does the exposed pad on the substitute part affect PCB layout?

A: The MX6AWT-A1-0000-000E51 features a 2-SMD, Gull Wing Exposed Pad configuration compared to the standard 2-SMD, Gull Wing of the main part. The exposed pad provides enhanced thermal dissipation. PCB layout must accommodate the exposed pad connection if thermal performance optimization is desired.

Q: Are there any compliance or certification differences?

A: The substitute is RoHS Compliant, whereas the main part does not specify RoHS status. Both parts are REACH Unaffected. The substitute's explicit RoHS certification provides regulatory advantage for applications subject to RoHS requirements.

Q: What is the inventory status of these parts?

A: The main part (MX6SWT-A1-0000-000G51) has 1055 Pcs in stock but is obsolete. The substitute (MX6AWT-A1-0000-000E51) has 726 Pcs in stock and is active, ensuring continued availability.
