M2018ES2G13 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2018ES2G13 is an NKK Switches toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 0.4VA at 28V AC/DC. This through-hole mounted component features a momentary-off-momentary (Mom-Off-Mom) switch function with epoxy sealed terminals and operates across -30°C to 85°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the M2018ES2G13 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (0.4VA AC/DC minimum)
• Voltage rating (minimum 28V AC/DC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Actuator length (11.40mm nominal tolerance)

Substitute Categories:

Manufacturer Recommended: MN18ES2G13 (NKK Switches) — Direct manufacturer equivalent with identical electrical and mechanical specifications, differing only in packaging format (Bulk vs. Tray).

Similar Alternatives: 7105P3Y9V3BE and 7105P3Y9V4BE (C&K) — Both parts meet core electrical requirements (SPDT, Mom-Off-Mom, 0.4VA, PC Pin termination, through-hole mounting, -30°C to 85°C operation). These C&K parts operate at 20V AC/DC, which is below the M2018ES2G13 rating of 28V. Substitution is valid for applications operating at or below 20V. Actuator length is 11.43mm, within acceptable mechanical tolerance. Electrical life is 40,000 cycles versus 50,000 cycles for the original part.

Parameter Comparison

Engineering Selection Recommendations

First Choice: MN18ES2G13 (NKK Switches)

The MN18ES2G13 is the manufacturer-recommended equivalent. As an active product from NKK Switches, it provides direct functional equivalence to the obsolete M2018ES2G13. Both parts share the same base product number (M2018ES) and are ROHS3 compliant. Selection of this part eliminates substitution risk and maintains design continuity with the original component family.

Alternative Choice: 7105P3Y9V3BE or 7105P3Y9V4BE (C&K)

The C&K 7105P3 series parts are suitable substitutes for applications where the circuit operates at 20V AC/DC or lower. These parts meet all core electrical and mechanical requirements: SPDT configuration, Mom-Off-Mom function, 0.4VA current rating, PC Pin termination, through-hole mounting, and -30°C to 85°C operation. Both parts are ROHS3 compliant and active products with confirmed inventory availability.

Voltage Consideration: Applications designed for the full 28V rating of the M2018ES2G13 cannot use the C&K alternatives without circuit redesign or voltage derating. Applications operating at 20V or below may use either C&K part without restriction.

Electrical Life Consideration: The C&K parts specify 40,000 electrical cycles versus 50,000 cycles for the original part. For applications requiring extended cycle life, the MN18ES2G13 is preferred.

Frequently Asked Questions (FAQ)

Q: Can the MN18ES2G13 be used as a direct replacement for the M2018ES2G13?

A: Yes. The MN18ES2G13 is the manufacturer-recommended equivalent with identical electrical specifications, circuit configuration, and mechanical form factor. The only difference is packaging format (Bulk versus Tray). No circuit modifications are required.

Q: What is the voltage limitation of the C&K 7105P3 series substitutes?

A: The 7105P3Y9V3BE and 7105P3Y9V4BE are rated for 20V AC/DC maximum, compared to 28V for the M2018ES2G13. These parts are suitable only for circuits operating at 20V or lower. For applications requiring 28V operation, use the MN18ES2G13.

Q: Are the 7105P3Y9V3BE and 7105P3Y9V4BE interchangeable with each other?

A: Yes. Both parts share identical electrical and mechanical specifications. Selection between them may be based on packaging availability or supplier preference.

Q: What is the significance of the 11.43mm actuator length in the C&K parts versus 11.40mm in the original?

A: The 0.03mm difference is within standard mechanical tolerance for toggle switch actuators and does not affect functional compatibility or panel mounting. Both dimensions accommodate standard 6.50mm circular panel cutouts.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The MN18ES2G13, 7105P3Y9V3BE, and 7105P3Y9V4BE are all ROHS3 compliant, matching the compliance status of the M2018ES2G13.

Q: What is the difference in electrical life between the original part and C&K substitutes?

A: The M2018ES2G13 specifies 50,000 electrical cycles, while the C&K 7105P3 series specifies 40,000 cycles. For applications with high cycle count requirements, the MN18ES2G13 or original M2018ES2G13 is preferred.

Q: Are there any REACH or ECCN differences between the substitute parts?

A: The MN18ES2G13 has not specified REACH status. The C&K parts indicate REACH Affected status. All parts are classified as EAR99 for export control purposes. Verify REACH compliance requirements with your supply chain for the specific application jurisdiction.
