Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS22BSW40 is determined by the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current Rating: 6A AC minimum requirement
• Voltage Rating: 125V AC minimum requirement
• Contact Timing: Non-Shorting (BBM) contact sequence
• Switch Function: On-On operation
• Mounting Type: Through Hole, Right Angle, Vertical configuration
• Termination Style: PC Pin termination
• Compliance: ROHS3 compliance and EAR99 ECCN classification

The MSN22BSW40, manufactured by NKK Switches, meets all specified electrical and mechanical parameters and is classified as an active product, making it a direct substitute for the obsolete MS22BSW40.
