Engineering Selection Recommendations

The MN12TJW01-FC-2A-C is identified as an active substitute for the obsolete M2012TJW01-FC-2A-C. Both parts are manufactured by NKK Switches and share identical electrical ratings, circuit configuration, and mechanical interface specifications.

The primary advantage of selecting the MN12TJW01-FC-2A-C is its active product status, ensuring ongoing availability and supply chain continuity. The substitute part maintains full functional equivalence across all specified electrical parameters: 6A AC / 4A DC current capacity, 125V AC / 30V DC voltage ratings, SPDT configuration, and On-On switch function.

Mechanical compatibility is confirmed through matching panel mount snap-in installation, solder lug termination, and identical panel cutout dimensions of 15.90mm x 12.50mm. The red illuminated concave actuator with LED illumination at 2.8 VDC nominal voltage is preserved in the substitute part.

Selection of the MN12TJW01-FC-2A-C is appropriate for applications currently using or designed for the M2012TJW01-FC-2A-C, with no circuit redesign or mechanical modification required.
