Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SB3W01 is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (minimum 6A AC / 3A DC)
• Voltage rating (minimum 125V AC / 30V DC)
• Mounting type (Panel Mount, Rear)
• Termination style (Solder Lug)
• Ingress protection rating (IP67 or equivalent)
• Operating temperature range (-30°C to 85°C or broader)
• RoHS compliance status

The MBN15SB3W01, manufactured by NKK Switches, is identified as a substitute part. This part maintains compatibility with the electrical and mechanical interface requirements of the MB2011SB3W01 application space.

Parameter Comparison

Engineering Selection Recommendations

The MBN15SB3W01 is the manufacturer-recommended substitute for the obsolete MB2011SB3W01. Both parts are manufactured by NKK Switches and maintain ROHS3 compliance, ensuring regulatory alignment for new designs and legacy system support.
