Substitute Part Grouping Explanation

The substitute part MN12S3S2W45 is classified as an equivalent replacement based on the following criteria:

• Identical manufacturer (NKK Switches)
• Same product category and functional classification (Toggle Switch)
• Matching electrical classification (ECCN: EAR99)
• Identical tariff classification (HTSUS: 8536.50.9065)
• Active product status ensuring continued availability and supply chain support

The substitution is valid where the M2012S3S2W45 is specified, provided the mechanical and electrical interface requirements of the application are met by the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The MN12S3S2W45 is the designated substitute for the obsolete M2012S3S2W45. Selection of the substitute part is based on:

• Product status transition: The original part is obsolete; the substitute maintains active status with established supply chain availability
• Regulatory compliance: Both parts share identical ECCN and HTSUS classifications, ensuring equivalent export control and tariff treatment
• Manufacturer continuity: Both parts are manufactured by NKK Switches, maintaining design lineage and quality standards

For applications currently using M2012S3S2W45, transition to MN12S3S2W45 is supported by matching functional classification and regulatory status.
