Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2065SS4W01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (6A AC / 125V, 3A DC / 30V)
• Mounting type (Panel Mount, Rear)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications
• RoHS3 compliance

The substitute part MBN12SS4W01, manufactured by NKK Switches, meets all these critical parameters and is classified as an active product, providing continuity for applications requiring the MB2065SS4W01.
