C&K 7103K2CWCGE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103K2CWCGE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch features a locking lever actuator, non-illuminated design, and IP67 ingress protection with epoxy sealed terminals. The component is currently active in production status.

Substitute parts become necessary when the primary component experiences supply discontinuation, extended lead times, or when design requirements permit alternative configurations that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103K2CWCGE is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain functional equivalence
• Switch Function: Must support On-Off-On operation
• Current Rating: Substitute must meet or exceed 5A rating
• Voltage Rating - AC: Substitute must meet or exceed 120V AC
• Voltage Rating - DC: Substitute must meet or exceed 28V DC
• Mounting Type: Must be Panel Mount for mechanical compatibility
• Panel Cutout Diameter: Must be compatible with 6.35mm circular cutout
• Bushing Thread: Must be 1/4-40 for panel installation
• Termination Style: Must be PC Pin for electrical connection compatibility
• Ingress Protection: IP67 rating provides environmental sealing specification
• Operating Temperature Range: Must encompass or exceed -30°C to 85°C
• Regulatory Compliance: RoHS3 and REACH status must be maintained

The NKK Switches M2113TCFW03 is identified as a substitute part based on matching circuit configuration, switch function, mounting type, panel cutout compatibility, bushing thread specification, and termination style. However, specific parameter deviations exist and must be evaluated for application suitability.

Engineering Selection Recommendations

The C&K 7103K2CWCGE maintains active product status with full regulatory compliance under ROHS3 and REACH Affected classifications. This component is the preferred selection for new designs and ongoing production applications.

The NKK Switches M2113TCFW03 carries obsolete product status, indicating discontinued manufacturing and limited availability. This substitute presents the following considerations:

• Voltage Ratings: The M2113TCFW03 exceeds AC and DC voltage specifications (125V AC vs. 120V AC; 30V DC vs. 28V DC), providing margin for voltage rating compatibility.
• Current Rating - AC: The M2113TCFW03 provides 6A AC rating, exceeding the 5A requirement.
• Current Rating - DC: The M2113TCFW03 provides 3A DC rating, which falls below the 5A DC specification of the primary part. This represents a critical limitation for DC applications.
• Operating Temperature Range: The M2113TCFW03 range (-10°C to 55°C) is narrower than the primary part (-30°C to 85°C), restricting use in extended temperature environments.
• Electrical Life: The M2113TCFW03 provides 25,000 cycles versus 40,000 cycles for the primary part, indicating reduced operational durability.
• Panel Cutout Diameter: The M2113TCFW03 requires 6.50mm diameter versus 6.35mm for the primary part. Panel modification may be required.
• Regulatory Compliance: Both components maintain ROHS3 compliance. The M2113TCFW03 is REACH Unaffected, while the primary part is REACH Affected.

Substitution with the M2113TCFW03 is limited to AC applications within the -10°C to 55°C temperature range where the reduced electrical life and panel cutout diameter modification are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the NKK Switches M2113TCFW03 replace the C&K 7103K2CWCGE in all applications?

A: No. The M2113TCFW03 has a 3A DC current rating, which is insufficient for applications requiring the full 5A DC rating of the primary part. Additionally, the operating temperature range is restricted to -10°C to 55°C, limiting use in extended temperature environments. Substitution is viable only for AC applications within this temperature range.

Q: What is the significance of the panel cutout diameter difference?

A: The primary part requires a 6.35mm circular cutout, while the substitute requires 6.50mm. This 0.15mm difference may necessitate panel modification or reaming to accommodate the larger bushing diameter. Mechanical compatibility must be verified before implementation.

Q: Why is the M2113TCFW03 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Availability is limited to existing inventory. For new designs or long-term production requirements, the active C&K 7103K2CWCGE is the recommended selection.

Q: Are both components RoHS3 compliant?

A: Yes. Both the C&K 7103K2CWCGE and NKK Switches M2113TCFW03 maintain ROHS3 compliance. However, the primary part is REACH Affected while the substitute is REACH Unaffected, which may influence regulatory documentation requirements depending on application jurisdiction.

Q: What is the electrical life difference, and does it matter?

A: The primary part provides 40,000 electrical cycles versus 25,000 for the substitute. For applications with high switching frequency or extended operational life requirements, the primary part offers superior durability. The substitute is suitable for moderate-duty applications.

Q: Can the M2113TCFW03 be used in DC applications?

A: The M2113TCFW03 is rated for 3A DC, which is below the 5A DC requirement of the primary part. Use in DC applications is limited to circuits drawing 3A or less. For full 5A DC capability, the primary part is required.
