MX6SWT-A1-0000-000CZ5 Equivalent & Substitute Parts

Part Overview

The MX6SWT-A1-0000-000CZ5 is an XLamp® MX-6S neutral white LED (4000K) designed for surface mount applications requiring 20V forward voltage and 60mA test current. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The substitute part maintains the same color temperature, viewing angle, and physical footprint while operating at different electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000CE5 qualifies as a substitute based on the following matching parameters:

• Color and CCT: Both parts are white, neutral 4000K LEDs
• Luminous flux: Identical flux output at 25°C test conditions (104lm, 100lm ~ 107lm range)
• Viewing angle: Both maintain 120° viewing angle
• Physical footprint: Identical 5.00mm x 5.00mm dimensions and 1.48mm maximum seated height
• Thermal characteristics: Matching 5°C/W thermal resistance
• Moisture sensitivity: Both rated 2A (4 Weeks) MSL
• Compliance: Both REACH Unaffected and EAR99 classified

The primary differences are electrical parameters (forward voltage and test current) and product status (obsolete vs. active). The substitute operates at 3.3V/300mA versus the original 20V/60mA, requiring circuit redesign for voltage and current compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts is determined by circuit voltage and current requirements:

MX6SWT-A1-0000-000CZ5 is suitable only for existing designs already in production or maintenance phases, as this part is obsolete and inventory is limited (949 pcs).

MX6AWT-A1-0000-000CE5 is the recommended choice for new designs and ongoing production. This part is active, RoHS compliant, and available in higher quantities (4545 pcs). The substitute delivers superior luminous efficiency (105 lm/W vs. 87 lm/W) and operates at standard low-voltage levels (3.3V), typical for modern LED driver circuits.

Circuit redesign is mandatory when transitioning from the MX6SWT to the MX6AWT due to the significant difference in forward voltage (20V to 3.3V) and test current (60mA to 300mA). Both parts maintain identical optical characteristics (4000K, 104lm, 120° viewing angle) and physical dimensions, ensuring compatibility at the mechanical and thermal levels.

Frequently Asked Questions (FAQ)

Q: Can MX6AWT-A1-0000-000CE5 be used as a direct drop-in replacement for MX6SWT-A1-0000-000CZ5?

A: No. While both parts share identical physical dimensions, color temperature, and luminous flux, they require different electrical operating conditions. The MX6SWT operates at 20V/60mA, while the MX6AWT operates at 3.3V/300mA. Circuit redesign of the LED driver and power supply is necessary.

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

A: Substitution is based on matching color (white, neutral), CCT (4000K), luminous flux (104lm at 25°C), viewing angle (120°), physical footprint (5.00mm x 5.00mm), and thermal characteristics (5°C/W). Electrical parameters (voltage and current) are application-specific and do not prevent substitution if the circuit is redesigned accordingly.

Q: Are there packaging differences between these parts?

A: Yes. The MX6SWT uses standard 2-SMD Gull Wing packaging, while the MX6AWT uses 2-SMD Gull Wing with an exposed pad. The exposed pad on the MX6AWT provides improved thermal management. Both parts maintain the same 5.00mm x 5.00mm footprint and 1.48mm maximum height, allowing PCB layout compatibility with thermal pad modifications.

Q: What is the inventory status for each part?

A: MX6SWT-A1-0000-000CZ5 has 949 pcs in stock but is classified as obsolete. MX6AWT-A1-0000-000CE5 has 4545 pcs in stock and is active. For new designs, the active part is recommended to ensure long-term supply availability.

Q: How do the efficiency ratings compare?

A: The MX6AWT delivers 105 lm/W at its test current (300mA), compared to 87 lm/W for the MX6SWT at its test current (60mA). This represents a 21% efficiency improvement, resulting in lower power consumption and reduced thermal load in the application circuit.

Q: Are both parts compliant with environmental regulations?

A: Both parts are REACH Unaffected and EAR99 classified. The MX6AWT is additionally RoHS Compliant. Both maintain 2A (4 Weeks) moisture sensitivity level, requiring identical handling and storage protocols.
