Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS2W45-BA is determined by strict alignment with the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Momentary operation)
• Current and voltage ratings (6A AC @ 125V; 3A DC @ 30V)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator type (Round Button)
• Termination style (PC Pin)
• Operating temperature range (-30°C to +85°C)
• Mechanical and electrical life specifications
• Panel cutout dimensions (Circular - 6.50mm Diameter)
• RoHS compliance status

The identified substitute part MBN25SS2W45-BA is classified as an equivalent component within the NKK Switches product portfolio. Substitution is valid only when all electrical, mechanical, and environmental parameters align with the specifications listed above.
