NKK Switches M2T18TXW13 Equivalent & Substitute Parts

Part Overview

The NKK Switches M2T18TXW13 is a rocker switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A AC at 125V and 3A DC at 30V. This through-hole mounted switch features a momentary-off-momentary (Mom-Off-Mom) function and is sealed for environmental protection. The M2T18TXW13 is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The M2T18TXW13 has one direct equivalent substitute: M2018TXW13. This substitution is valid based on the following matching electrical and mechanical parameters:

• Circuit configuration: Both are SPDT
• Switch function: Both are Mom-Off-Mom
• Current ratings: Both rated 6A AC / 3A DC
• Voltage ratings: Both rated 125V AC / 30V DC
• Mounting: Both are through-hole mounted with PC pin termination
• Operating temperature: Both operate -30°C to 85°C
• Mechanical and electrical life: Both rated 50,000 mechanical cycles / 25,000 electrical cycles
• Regulatory compliance: Both CSA and UL approved, ROHS3 compliant

The primary difference between these parts is the sealing method: M2T18TXW13 uses process sealing, while M2018TXW13 uses epoxy sealed terminals. Both methods provide equivalent environmental protection for this switch category.

Parameter Comparison

Engineering Selection Recommendations

Both M2T18TXW13 and M2018TXW13 are obsolete products from NKK Switches. Selection between these parts should be based on:

• Sealing requirements: Process sealing (M2T18TXW13) versus epoxy sealed terminals (M2018TXW13). Both provide equivalent environmental protection for standard applications.
• Availability: Verify current inventory status with suppliers, as both parts are obsolete.
• PCB design compatibility: Both use identical through-hole PC pin termination, ensuring mechanical and electrical compatibility with existing designs.
• Regulatory compliance: Both parts meet CSA and UL approvals and are ROHS3 compliant, suitable for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can M2018TXW13 directly replace M2T18TXW13 in existing designs?

A: Yes. Both parts share identical electrical ratings (6A AC / 3A DC at 125V AC / 30V DC), circuit configuration (SPDT Mom-Off-Mom), mounting type (through-hole), and termination style (PC pin). The sealing method difference does not affect electrical or mechanical compatibility.

Q: What is the difference between process sealing and epoxy sealed terminals?

A: Process sealing and epoxy sealed terminals are both environmental protection methods. Process sealing is applied during manufacturing, while epoxy sealed terminals use epoxy coating on the terminal connections. Both provide equivalent protection for this switch category.

Q: Are there any packaging differences between these parts?

A: The main part M2T18TXW13 is supplied in bulk packaging. M2018TXW13 packaging information is not specified in the available data. Confirm packaging requirements with your supplier.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both M2T18TXW13 and M2018TXW13 are CSA and UL approved and ROHS3 compliant, meeting identical regulatory requirements.

Q: What is the mechanical life expectancy of these switches?

A: Both parts are rated for 50,000 mechanical cycles and 25,000 electrical cycles, providing equivalent operational longevity.

Q: Can these switches operate in the same temperature range?

A: Yes. Both parts operate across the identical temperature range of -30°C to 85°C.
