Substitute Part Grouping Explanation

Substitution of the MB2185SS4G01 is based on the following criteria derived from the provided parameters:

• Functional category: Pushbutton switch
• Manufacturer compatibility: NKK Switches
• Electrical characteristics: Circuit configuration (4PDT), voltage rating (28V AC/DC), current rating (0.4VA AC/DC)
• Mechanical characteristics: Mounting type (Panel Mount, Rear), actuator type (Plunger for Cap), termination style (Solder Lug)
• Switch function: On-On operation
• Panel cutout dimensions: Circular 6.50mm diameter

The substitute part MBN42SS4G01 meets these criteria as an active product within the NKK Switches MB2000 series, providing direct functional equivalence for the obsolete MB2185SS4G01.

Engineering Selection Recommendations

The MBN42SS4G01 is the manufacturer-recommended substitute for the obsolete MB2185SS4G01. Selection of this substitute is based on:

• Active product status within the NKK Switches MB2000 series, ensuring long-term availability and supply chain continuity
• Functional equivalence as a 4PDT pushbutton switch with identical electrical ratings (28V AC/DC, 0.4VA)
• Mechanical compatibility with panel mount rear installation and solder lug termination
• Adequate inventory availability (983 pieces in stock) supporting production requirements

Frequently Asked Questions (FAQ)

Q: Can the MBN42SS4G01 directly replace the MB2185SS4G01 in existing applications?

A: Yes. The MBN42SS4G01 provides direct functional replacement based on matching circuit configuration (4PDT), voltage ratings (28V AC/DC), current rating (0.4VA), mounting type (Panel Mount, Rear), and termination style (Solder Lug). Physical panel cutout dimensions are identical (Circular 6.50mm diameter).

Q: Why is the MB2185SS4G01 classified as obsolete?

A: The MB2185SS4G01 has been discontinued by NKK Switches. The MBN42SS4G01 within the active MB2000 series represents the current production equivalent.

Q: What are the critical parameters for substitution compatibility?

A: Critical parameters include circuit type (4PDT), voltage rating (28V AC/DC), current capacity (0.4VA), mounting configuration (Panel Mount, Rear), actuator type (Plunger for Cap), termination method (Solder Lug), and panel cutout dimensions (Circular 6.50mm diameter).

Q: Are there inventory considerations for component selection?

A: Both the original MB2185SS4G01 (836 pieces) and substitute MBN42SS4G01 (983 pieces) maintain adequate stock levels. The active status of MBN42SS4G01 ensures continued availability for future procurement.
