Key Parameters

Substitute Part Grouping Explanation

Substitution of the TFCGV3VT145BC is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-Momentary
• Current Rating: Must support minimum 11A AC and 500mA DC
• Voltage Rating: Must support minimum 277V AC and 125V DC
• Actuator Type: Must be Lever with Simulated Roller
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Quick Connect - 0.187" (4.7mm)
• Operating Temperature Range: Must encompass -40°C to 85°C
• Mechanical Specifications: Operating Force, Operating Position, Pretravel, Differential Travel, and Overtravel must match specified values

The TFCGK6ST1440C meets all these criteria and is therefore a direct functional equivalent.
