Substitute Part Grouping Explanation

Substitution of the M2018TYW01-HG is based on electrical and mechanical compatibility within the NKK Switches product family. The primary substitute identified is the MN18TYW01-HG, which shares the same base product lineage (M/MN18TY series) and manufacturer certification framework under EAR99 export classification and HTSUS code 8536.50.9065.

The substitution logic is determined by the following critical parameters:

• Circuit Configuration: SPDT topology for equivalent switching paths
• Current and Voltage Ratings: Minimum 6A AC at 125V and 3A DC at 30V capability
• Mounting Interface: Panel mount compatibility with flange configuration
• Termination Method: Solder lug connection for PCB integration
• Environmental Compliance: CSA and UL certifications for regulatory acceptance
• Mechanical Durability: Minimum 50,000 mechanical cycles and 25,000 electrical cycles

Parameter Comparison

Engineering Selection Recommendations

The M2018TYW01-HG is classified as obsolete. For applications currently utilizing this component, the MN18TYW01-HG is identified as the manufacturer-recommended substitute within the NKK Switches portfolio. Both parts share identical export classification (EAR99) and tariff coding (HTSUS 8536.50.9065), indicating regulatory alignment.

The MN18TYW01-HG maintains active product status, ensuring continued availability and manufacturing support. Selection of the substitute part is appropriate for new designs and replacement applications where the electrical and mechanical interface requirements of the original specification are maintained.

Verification of specific electrical parameters (current rating, voltage rating, circuit configuration, and mechanical life) against application requirements is necessary prior to implementation, as detailed specification data for the substitute part is limited in the provided documentation.

Frequently Asked Questions (FAQ)

Q: Can the MN18TYW01-HG directly replace the M2018TYW01-HG in existing applications?

A: The MN18TYW01-HG is the manufacturer-recommended substitute and shares the same base product family designation (M/MN18TY series). Both parts are manufactured by NKK Switches and carry identical export and tariff classifications. However, complete electrical and mechanical parameter alignment must be confirmed against your specific application requirements before implementation.

Q: What is the difference between the M2018TYW01-HG and MN18TYW01-HG part numbers?

A: The primary difference is product status: M2018TYW01-HG is obsolete, while MN18TYW01-HG is active. The MN designation indicates a mini flat frame configuration. Both parts are sourced from NKK Switches and fall under the same regulatory and tariff frameworks.

Q: Are there packaging differences between these parts?

A: The M2018TYW01-HG packaging specification is not provided in the documentation. The MN18TYW01-HG is available in bulk packaging. Packaging requirements should be confirmed with your procurement specifications.

Q: What certifications apply to both parts?

A: Both parts are classified under EAR99 export control and HTSUS code 8536.50.9065. The M2018TYW01-HG carries CSA and UL approvals. Certification status for the MN18TYW01-HG should be verified with the manufacturer.

Q: Is inventory availability a factor in part selection?

A: Current inventory shows 681 pieces of M2018TYW01-HG and 810 pieces of MN18TYW01-HG available as new original stock. Inventory levels are subject to change and should be confirmed at the time of procurement.
