Parameter Comparison

Engineering Selection Recommendations

The MBN15SS4W03-CA is an active product offering from NKK Switches and maintains ROHS3 compliance. Selection of this substitute is appropriate for applications where the obsolete MB2011SS4W03-CA is no longer available through standard supply channels.

The primary distinction between these components is the mounting configuration: the MB2011SS4W03-CA uses Panel Mount, Rear mounting, while the MBN15SS4W03-CA uses Bushing Mount. This difference requires mechanical design consideration during component integration. Both components share identical electrical specifications, circuit configuration, and termination methodology.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between MB2011SS4W03-CA and MBN15SS4W03-CA?

A: The primary difference is the mounting type. The MB2011SS4W03-CA uses Panel Mount, Rear configuration, while the MBN15SS4W03-CA uses Bushing Mount. Both maintain identical electrical ratings, SPDT circuit configuration, and PC pin termination.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components share the same current ratings (6A AC, 3A DC), voltage ratings (125V AC, 30V DC), switch function (On-Momentary), and circuit configuration (SPDT).

Q: What does the mounting type difference mean for my application?

A: Panel Mount, Rear mounting secures the switch from the rear of the panel with a threaded connection. Bushing Mount uses a bushing-based fastening method. Your mechanical design must accommodate the specific mounting method of the selected component.

Q: Are both parts RoHS compliant?

A: The MB2011SS4W03-CA is ROHS3 compliant. Compliance status for the MBN15SS4W03-CA is based on the provided specification data.

Q: What is the packaging difference?

A: The MB2011SS4W03-CA packaging is not specified in the available data. The MBN15SS4W03-CA is supplied in Bulk packaging.
