Substitute Part Grouping Explanation

The MN12ES4W03 qualifies as a direct substitute based on the following criteria:

• Identical manufacturer (NKK Switches)
• Matching product category and functional description (Toggle Switch)
• Equivalent ECCN classification (EAR99)
• Matching HTSUS tariff code (8536.50.9065)
• Active product status with current manufacturing availability

The substitution is valid where the M2012ES4W03 is specified, provided the mechanical packaging and electrical interface requirements of the application are compatible with the substitute part's form factor.

Parameter Comparison

Engineering Selection Recommendations

The MN12ES4W03 is the primary substitute for the obsolete M2012ES4W03. Selection between the original part (if available from inventory) and the substitute should be based on:

• Application timeline and inventory requirements
• Mechanical fit and electrical interface compatibility with the target circuit board or assembly
• Compliance requirements matching the EAR99 and HTSUS classifications, which are identical for both parts
• Supply chain continuity, as the MN12ES4W03 maintains active production status

Frequently Asked Questions (FAQ)

Q: Can the MN12ES4W03 directly replace the M2012ES4W03 in all applications?

A: The MN12ES4W03 is functionally equivalent based on category, manufacturer, and regulatory classification. Direct replacement is valid where mechanical packaging and electrical interface specifications are compatible with the application's design constraints.

Q: Why is the M2012ES4W03 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The MN12ES4W03 serves as the current-generation equivalent from the same manufacturer.

Q: Are the ECCN and HTSUS classifications the same for both parts?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, ensuring equivalent regulatory treatment in export and tariff applications.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The M2012ES4W03 is obsolete, while the MN12ES4W03 is actively manufactured. Both are toggle switches from NKK Switches with matching electrical and regulatory characteristics.
