Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2061SS4W01-CG is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom momentary operation)
• Current ratings (6A AC / 3A DC minimum)
• Voltage ratings (125V AC / 30V DC minimum)

Mechanical Compatibility Parameters:

• Mounting type (Panel Mount, Rear)
• Actuator type (Round, Button)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Termination style (Solder Lug)

Environmental Compatibility Parameters:

• Operating temperature range (-30°C to 85°C)
• Mechanical life (100,000 cycles minimum)
• Electrical life (25,000 cycles minimum)

The substitute part MBN25SS4W01-CG is identified as a direct equivalent based on manufacturer designation and functional alignment with these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MBN25SS4W01-CG is the designated substitute for the obsolete MB2061SS4W01-CG. This substitution is based on complete parameter alignment across electrical, mechanical, and environmental specifications. The substitute part carries active product status from NKK Switches, ensuring ongoing availability and manufacturing support.

Selection of the MBN25SS4W01-CG for replacement applications is appropriate where the MB2061SS4W01-CG is no longer procurable. The electrical performance envelope, mechanical interface, and environmental operating range are identical between the two parts, supporting direct substitution in existing circuit designs and panel mount configurations.
