Frequently Asked Questions (FAQ)

Q: Can the MN18TJW01-FB-2A-C directly replace the M2018TJW01-FB-2A-C in existing designs?

A: The MN18TJW01-FB-2A-C is the manufacturer-recommended substitute. Compatibility is determined by matching the circuit configuration (SPDT), switch function (Mom-Off-Mom), current and voltage ratings, mounting interface (panel snap-in), and termination style (solder lug). Detailed electrical and mechanical specifications for the substitute part should be confirmed against application requirements.

Q: What is the significance of the product status change from Obsolete to Active?

A: The main part M2018TJW01-FB-2A-C is obsolete, meaning NKK Switches no longer manufactures it. The substitute MN18TJW01-FB-2A-C carries active status, indicating current production and availability. This transition ensures continued supply for applications requiring this switch type.

Q: Are there any differences in panel cutout dimensions between these parts?

A: The panel cutout dimension for the main part is specified as rectangular 15.90mm x 12.50mm. Corresponding dimensions for the substitute part are not provided in the available data. Physical verification is necessary before installation in existing panel assemblies.

Q: Do both parts meet the same regulatory approvals?

A: The main part carries CSA and UL approvals. Regulatory approval status for the substitute part is not specified in the available data. Confirmation of applicable certifications for the MN18TJW01-FB-2A-C should be obtained from NKK Switches technical documentation.

Q: What is the basis for the substitution recommendation?

A: The substitution is based on manufacturer designation as the recommended equivalent. Both parts are from NKK Switches and share identical ECCN and HTSUS trade classifications. The part number structure indicates a product line evolution within the same manufacturer's rocker switch family.
