Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SB3G03-BA is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for functional compatibility
• Voltage and Current Ratings: 28V AC/DC at 0.4VA minimum capacity
• Switch Function: On-Momentary operation required
• Mounting Interface: Panel Mount, Rear configuration with circular 12.50mm diameter cutout
• Termination: PC Pin termination for PCB integration
• Environmental Protection: IP67 rating for dust and moisture ingress protection
• Operating Temperature: -30°C to 85°C range capability
• Mechanical and Electrical Life: 50,000 cycles minimum

The identified substitute MBN15SB3G03-BA from NKK Switches maintains these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring the MB2011SB3G03-BA specifications.
