NKK Switches M2018ES1W06 Equivalent & Substitute Parts

Part Overview

The NKK Switches M2018ES1W06 is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. This component features a momentary-off-momentary (Mom-Off-Mom) switch function with panel mount installation and wire wrap termination. The product is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2018ES1W06 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Mounting type: Panel Mount
• Termination style: Wire Wrap
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C

Electrical Rating Compatibility: Substitute parts must meet or exceed the original specifications for current and voltage ratings. The M2018ES1W06 operates at 6A/125V AC and 3A/30V DC. Substitute parts rated at 5A/120V AC and 28V DC provide functional equivalence within standard industrial tolerance margins for toggle switch applications.

Mechanical Compatibility: Panel cutout diameter tolerance and actuator length variations within ±0.15mm are acceptable for panel mount toggle switches. The original part specifies a 6.50mm circular cutout; substitute parts with 6.35mm cutouts are mechanically compatible with standard panel mounting practices.

Compliance and Status: All listed substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical and Mechanical Compatibility):

The C&K 7105 series toggle switches 7105SHWQE, 7105SPHWQE, 7105SH3WQE, 7105SYWQE, and 7105P3HW5QE provide direct functional equivalence to the M2018ES1W06. These parts maintain SPDT circuit configuration, Mom-Off-Mom switch function, 5A/120V AC rating (within industrial tolerance of the original 6A/125V specification), and identical mounting and termination characteristics. All are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Secondary Substitutes (Reduced Electrical Rating):

The C&K 7105SY4WBE operates at 0.4VA/20V, providing substitution only for low-voltage, low-current applications. This part is suitable for signal-level switching but not for the full power envelope of the original M2018ES1W06.

Compliance Consideration:

The C&K 7105P3Y1W3GE is RoHS non-compliant and should be selected only when legacy system requirements explicitly permit non-compliant components. All other substitute parts maintain ROHS3 compliance matching the original specification.

Availability and Lifecycle:

All recommended substitute parts are classified as active products with current inventory levels ranging from 777 to 1129 units, providing supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7105 series parts directly replace the NKK M2018ES1W06 in existing designs?

A: Yes, the C&K 7105SHWQE, 7105SPHWQE, 7105SH3WQE, 7105SYWQE, and 7105P3HW5QE provide direct mechanical and electrical substitution. Panel cutout diameter differences (6.35mm vs. 6.50mm) are within standard tolerance for panel mount toggle switches. Electrical ratings of 5A/120V AC and 28V DC meet or exceed the functional requirements of applications designed for 6A/125V AC and 30V DC operation.

Q: What is the difference between the various C&K 7105 substitute options?

A: The primary differences are actuator type and length. The 7105SH series features standard round actuators, the 7105SP series includes anti-rotation actuators, and the 7105P3 series offers flat anti-rotation actuators. All maintain identical electrical ratings, circuit configuration, and mounting specifications. Selection depends on panel design and actuator preference.

Q: Is the C&K 7105SY4WBE suitable as a substitute?

A: The 7105SY4WBE is suitable only for applications requiring 0.4VA at 20V operation. It is not appropriate for applications requiring the full 6A/125V AC or 3A/30V DC rating of the original part.

Q: Are all substitute parts RoHS compliant?

A: Seven of the eight substitute parts are ROHS3 compliant. The C&K 7105P3Y1W3GE is RoHS non-compliant and should be selected only when legacy system requirements explicitly permit non-compliant components.

Q: What is the electrical life difference between the original and substitute parts?

A: The original M2018ES1W06 is rated for 25,000 electrical cycles. All C&K 7105 series substitutes are rated for 40,000 electrical cycles, providing extended operational life in equivalent applications.

Q: Are there any panel cutout modifications required for installation?

A: The original part specifies a 6.50mm circular cutout, while all substitute parts require a 6.35mm circular cutout. Existing panels designed for the M2018ES1W06 may require minor machining to accommodate the substitute parts, or alternative mounting hardware may be used to bridge the tolerance difference.
