Substitute Part Grouping Explanation

Substitution for the MB2185SS4W01 is based on the following criteria derived from available technical parameters:

• Manufacturer alignment: NKK Switches maintains product continuity within its portfolio
• Functional category: Pushbutton switch classification
• Active product status: Substitute parts must be in active production to ensure long-term availability
• Electrical specifications: Current rating, voltage rating (AC/DC), and circuit configuration
• Mechanical specifications: Mounting type, actuator type, and panel cutout dimensions
• Termination compatibility: Solder lug termination style

The MBN42SS4W01 qualifies as a manufacturer-recommended substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MBN42SS4W01 is designated as the manufacturer-recommended substitute for the obsolete MB2185SS4W01. This recommendation is based on:

• Active product status ensuring continued availability and manufacturing support
• Same manufacturer (NKK Switches) providing design continuity and quality consistency
• Documented electrical specifications (6A AC / 3A DC, 125V AC / 30V DC) enabling direct application assessment
• Standard panel mount configuration with defined mechanical interfaces
• Adequate inventory levels supporting production requirements

Selection of the MBN42SS4W01 requires verification that the 4PDT circuit configuration, On-On switch function, and 6.50mm panel cutout dimensions are compatible with the original application requirements.
