Substitute Part Grouping Explanation

The MN18B2B3A01-131A-A qualifies as a manufacturer-recommended substitute based on the following criteria:

• Identical manufacturer (NKK Switches)
• Matching product category (Toggle Switch)
• Identical ECCN classification (EAR99)
• Identical HTSUS code (8536.50.9065)
• Active product status, ensuring ongoing availability and support

The substitution is valid where the original M2018L/B-131A-A toggle switch is specified, provided the mechanical and electrical interface requirements of the application remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The MN18B2B3A01-131A-A is the appropriate substitute for the obsolete M2018L/B-131A-A. Selection is based on:

• Manufacturer recommendation from NKK Switches
• Matching regulatory classifications (ECCN EAR99, HTSUS 8536.50.9065)
• Active product status ensuring long-term availability and supply chain stability
• Equivalent functional classification as a toggle switch
