Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX6SWT-H1-0000-000D53 is determined by the following critical parameters:

Color Temperature & Photometric Output: Both the main part and substitute must maintain 6000K cool white color temperature with equivalent luminous flux output (111 lm nominal at test conditions) and CRI of 80 to preserve color rendering characteristics in the application.

Viewing Angle & Optical Properties: The 120° viewing angle is a fixed optical characteristic that must be maintained across substitutes to ensure consistent light distribution in the target application.

Mounting & Package Footprint: Surface mount technology with 2-SMD Gull Wing package configuration and 5.00 mm × 5.00 mm footprint dimensions are required for PCB compatibility.

Thermal & Environmental Compliance: Thermal resistance of 5°C/W, MSL rating of 2A, and REACH Unaffected status must be preserved to maintain thermal management and regulatory compliance.

Critical Difference - Electrical Operating Point: The primary distinction between the main part and its substitute lies in the forward voltage and test current specifications. The MX6SWT operates at 20V / 60 mA, while the substitute MX6AWT operates at 3.3V / 300 mA. This fundamental difference requires circuit redesign and is not a direct pin-compatible substitution. Selection depends on the application's power supply architecture and current handling capability.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000D53 is the designated substitute for the obsolete MX6SWT-H1-0000-000D53 based on the following engineering criteria:

Product Status & Availability: The MX6AWT is classified as Active with 661 pieces in stock, ensuring long-term supply continuity. The MX6SWT is obsolete with limited remaining inventory (965 pieces), making transition to an active part necessary for sustained production.

Regulatory Compliance: The MX6AWT carries RoHS Compliant certification, providing enhanced environmental compliance for applications subject to RoHS directives. Both parts maintain REACH Unaffected status and equivalent MSL ratings.

Photometric Equivalence: Both parts deliver identical luminous flux (111 lm at 25°C), color temperature (6000K), CRI (80), and viewing angle (120°), ensuring equivalent optical performance in the application.

Electrical Redesign Requirement: Direct substitution is not possible without circuit modification. The MX6AWT operates at 3.3V / 300 mA versus the MX6SWT's 20V / 60 mA. Applications must be redesigned to accommodate the lower voltage and higher current operating point. The MX6AWT delivers superior efficiency at 112 lm/W compared to 93 lm/W for the MX6SWT.

Package Compatibility: Both parts share identical footprint dimensions (5.00 mm × 5.00 mm) and height (1.48 mm). The MX6AWT features an exposed pad variant of the 2-SMD Gull Wing package, which may provide improved thermal performance in high-power applications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000D53 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000D53?

A: No. While both parts share identical footprint dimensions and optical characteristics, the MX6AWT operates at 3.3V / 300 mA whereas the MX6SWT operates at 20V / 60 mA. Circuit redesign is required to accommodate the different electrical operating point. Direct PCB substitution without power supply modification will result in component failure.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by color temperature (6000K), luminous flux (111 lm), CRI (80), viewing angle (120°), mounting type (surface mount), package footprint (5.00 mm × 5.00 mm), thermal resistance (5°C/W), and environmental compliance (REACH Unaffected, MSL 2A). Electrical operating voltage and current are application-dependent and do not prevent substitution if circuit redesign is performed.

Q: Are there any package differences between the MX6SWT and MX6AWT?

A: Both parts use 2-SMD Gull Wing packages with identical 5.00 mm × 5.00 mm footprints and 1.48 mm maximum seated height. The MX6AWT includes an exposed pad variant, which provides enhanced thermal dissipation compared to the standard Gull Wing configuration of the MX6SWT.

Q: What is the impact of the efficiency difference between these parts?

A: The MX6AWT delivers 112 lm/W at its test current (300 mA) compared to 93 lm/W for the MX6SWT at its test current (60 mA). This represents improved energy efficiency in the MX6AWT. However, efficiency comparisons must account for the different operating points; direct comparison requires normalization to equivalent operating conditions.

Q: Is the MX6AWT RoHS compliant?

A: Yes. The MX6AWT-H1-0000-000D53 is RoHS Compliant. The MX6SWT RoHS status is not specified in the available documentation. Both parts maintain REACH Unaffected status.

Q: What is the moisture sensitivity level for both parts?

A: Both the MX6SWT and MX6AWT carry an MSL rating of 2A (4 Weeks), indicating equivalent moisture sensitivity and requiring identical storage and handling protocols.
