M2018CS1G01-A Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2018CS1G01-A is a panel-mount toggle switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration and momentary-off-momentary (Mom-Off-Mom) switching function. Rated for 0.4VA at 28V AC/DC, this component features a standard round actuator with 14.50mm length and solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2018CS1G01-A is determined by the following critical parameters: circuit configuration (SPDT), switch function (Mom-Off-Mom), mounting type (panel mount), termination style (solder lug), bushing thread specification (1/4-40), and operating temperature range (-30°C to 85°C).

The substitute parts identified—7105L1PH3ZQE and 7105L1PH3ZQI from C&K—share identical circuit configuration, switch function, mounting type, termination style, bushing thread, and operating temperature range. Both substitute parts are manufactured by C&K within the 7000 series and maintain active product status.

Voltage and current ratings differ between the main part and substitutes. The M2018CS1G01-A operates at 0.4VA/28V, while both C&K substitutes are rated for 5A at 120V AC and 28V DC. The substitute parts feature anti-rotation actuators with 15.75mm length, compared to the standard round actuator with 14.50mm length on the original part. Panel cutout diameter differs slightly: 6.35mm for substitutes versus 6.50mm for the main part. Electrical life specification is 40,000 cycles for substitutes versus 50,000 cycles for the original.

Parameter Comparison

Engineering Selection Recommendations

Both C&K substitute parts maintain active product status, providing supply continuity for the obsolete M2018CS1G01-A. The 7105L1PH3ZQE is ROHS3 compliant and REACH affected, while the 7105L1PH3ZQI is RoHS non-compliant and REACH affected. Selection between these substitutes should prioritize compliance requirements specific to the application and regulatory jurisdiction.

The higher current rating (5A versus 0.4VA) and AC voltage rating (120V versus 28V) of the C&K substitutes provide enhanced electrical capacity. The anti-rotation actuator design on substitute parts differs from the standard round actuator on the original part. Actuator length increases from 14.50mm to 15.75mm, and panel cutout diameter decreases from 6.50mm to 6.35mm. These dimensional variations require mechanical compatibility verification within the host assembly. Electrical life specification decreases from 50,000 to 40,000 cycles on substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7105L1PH3ZQE and 7105L1PH3ZQI be used interchangeably with the M2018CS1G01-A?

A: Both C&K parts share identical circuit configuration (SPDT), switch function (Mom-Off-Mom), mounting type (panel mount), termination style (solder lug), bushing thread (1/4-40), and operating temperature range (-30°C to 85°C). However, dimensional differences in actuator length (15.75mm versus 14.50mm) and panel cutout diameter (6.35mm versus 6.50mm) require mechanical compatibility assessment within the specific assembly.

Q: What are the key electrical differences between the main part and substitutes?

A: The M2018CS1G01-A is rated for 0.4VA at 28V AC/DC. The C&K substitutes are rated for 5A at 120V AC and 28V DC. The substitute parts provide higher current and AC voltage capacity. Electrical life differs: 50,000 cycles for the original versus 40,000 cycles for substitutes.

Q: Which substitute part should be selected for RoHS compliance?

A: The 7105L1PH3ZQE is ROHS3 compliant. The 7105L1PH3ZQI is RoHS non-compliant. Selection depends on regulatory requirements applicable to the end application.

Q: Are there mechanical compatibility concerns with the substitute parts?

A: Yes. The substitute parts feature anti-rotation actuators with 15.75mm length compared to the standard round actuator with 14.50mm length on the original part. Panel cutout diameter is 6.35mm for substitutes versus 6.50mm for the main part. Panel mounting hole dimensions and actuator protrusion must be verified for compatibility within the host assembly.

Q: What is the inventory status of these parts?

A: The M2018CS1G01-A (obsolete) has 1,086 pieces in stock. The 7105L1PH3ZQE has 752 pieces in stock. The 7105L1PH3ZQI has 941 pieces in stock.
