Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SB3G03-DA is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Electrical ratings (0.4VA at 28V AC/DC)
• Mounting interface (Panel Mount, Rear with 12.50mm circular cutout)
• Termination style (PC Pin)
• Ingress protection level (IP67)
• Operating temperature range (-30°C ~ 85°C)
• Mechanical and electrical life specifications (50,000 cycles minimum)

The substitute part MBN15SB3G03-DA is identified as a manufacturer-recommended equivalent. Both parts originate from NKK Switches and maintain compatibility across the specified electrical and mechanical parameters.
