MX6SWT-H1-0000-000CF6 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-000CF6 is an XLamp® MX-6S warm white LED (3700K) designed for surface mount applications requiring 20V forward voltage and 60mA test current. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The MX-6S series has been superseded by the MX-6 series, which offers improved efficiency and active product status while maintaining core optical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000BF6 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Color and CCT: Both parts are White, Warm 3700K
• Viewing Angle: Both maintain 120° viewing angle
• Mounting Type: Both are surface mount
• Physical Dimensions: Both are 5.00mm x 5.00mm with 1.48mm max seated height
• CRI: Both have CRI of 80
• Thermal Resistance: Both have 5°C/W thermal resistance
• Moisture Sensitivity: Both are MSL 2A (4 Weeks)

Substitution Logic: The MX6AWT represents the active production equivalent within the XLamp® family. While forward voltage (3.3V vs. 20V) and test current (300mA vs. 60mA) differ significantly, these differences reflect the architectural evolution from MX-6S to MX-6 series and require circuit-level design accommodation. The substitute maintains identical optical output characteristics (warm white 3700K), mechanical compatibility (footprint and height), and reliability specifications (thermal and moisture ratings).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX6SWT-H1-0000-000CF6 is obsolete. The MX6AWT-H1-0000-000BF6 is active production, ensuring long-term availability and supply chain stability for new designs and ongoing production requirements.

Compliance and Certifications: The MX6AWT-H1-0000-000BF6 carries RoHS Compliant certification, meeting current regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Electrical Accommodation: Substitution requires circuit redesign to accommodate the voltage and current differences. The MX-6 series operates at 3.3V typical forward voltage with 300mA test current, compared to the MX-6S series 20V and 60mA. The substitute provides superior efficiency (98 lm/W vs. 87 lm/W), offsetting the flux difference (97lm vs. 104lm) at the respective test currents.

Mechanical and Thermal Compatibility: Both parts share identical footprint (5.00mm x 5.00mm), height (1.48mm), thermal resistance (5°C/W), and moisture sensitivity (MSL 2A). The MX6AWT features an exposed pad variant, which may improve thermal performance in applications requiring enhanced heat dissipation.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BF6 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000CF6?

A: No. While both parts share identical mechanical footprint and optical characteristics (warm white 3700K, 120° viewing angle), the forward voltage differs significantly (3.3V vs. 20V). Direct substitution requires circuit-level modifications to the LED driver and power supply design. The parts are not electrically interchangeable without redesign.

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

A: Substitution is based on matching color (White, Warm), CCT (3700K), viewing angle (120°), mounting type (surface mount), physical dimensions (5.00mm x 5.00mm, 1.48mm height), CRI (80), thermal resistance (5°C/W), and moisture sensitivity (MSL 2A). Electrical parameters (voltage and current) differ and require design accommodation.

Q: Why does the MX6AWT have lower flux (97lm vs. 104lm) but higher efficiency (98 lm/W vs. 87 lm/W)?

A: The flux values are measured at different test currents. The MX6AWT is tested at 300mA while the MX6SWT is tested at 60mA. At their respective test currents, the MX6AWT delivers superior lumens-per-watt efficiency, reflecting the improved design of the MX-6 series.

Q: What is the difference between the standard 2-SMD Gull Wing package and the 2-SMD Gull Wing Exposed Pad variant?

A: The exposed pad variant on the MX6AWT provides direct thermal contact to the PCB, improving heat dissipation. This is beneficial in high-power or thermally constrained applications. Both variants maintain the same footprint and height.

Q: Is the MX6AWT-H1-0000-000BF6 RoHS compliant?

A: Yes. The MX6AWT-H1-0000-000BF6 is RoHS Compliant. The MX6SWT product status does not specify RoHS compliance, which is consistent with its obsolete classification.

Q: What is the maximum current rating for each part?

A: The MX6SWT-H1-0000-000CF6 has a maximum current rating of 175mA. The MX6AWT-H1-0000-000BF6 has a maximum current rating of 1A, reflecting the lower voltage architecture of the MX-6 series.
