C&K 7201TCWCKE22 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201TCWCKE22 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 0.4VA at 20V AC/DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features IP67 ingress protection, non-illuminated operation, and PC pin termination suitable for industrial and commercial applications requiring sealed switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201TCWCKE22 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Actuator type: Standard Round
• Actuator length: 17.45mm
• Bushing thread: 15/32-32
• Panel cutout dimensions: Circular - 11.91mm Dia
• Operating temperature range: -30°C minimum, 85°C maximum

Electrical Compatibility Parameters:

• Current rating must equal or exceed 0.4VA
• Voltage ratings must equal or exceed 20V AC and 20V DC

Acceptable Variations:

• Product status (Active substitutes preferred for obsolete parts)
• RoHS compliance status
• Electrical life cycles (if equal to or greater than 100,000 cycles)
• Ingress protection rating (if equal to or greater than IP67)
• Terminal sealing features (epoxy sealed terminals acceptable)

Substitute parts are grouped into two categories: direct equivalents (identical electrical and mechanical specifications with updated product status) and similar alternatives (matching core parameters with higher electrical ratings).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - C&K 7201TCWCPE22: The 7201TCWCPE22 is the primary substitute for the obsolete 7201TCWCKE22. This part maintains identical electrical and mechanical specifications while offering active product status. The transition from black actuator to epoxy sealed terminals represents a manufacturing improvement. RoHS compliance status has been upgraded to compliant, and REACH status is now affected. This part is recommended for direct replacement in new designs and system maintenance where the original specification must be preserved.

Similar Alternative - Grayhill Inc. 34ADP18T7M2QT: The 34ADP18T7M2QT provides higher electrical ratings (5A at 125V AC, 28V DC) within the same mechanical envelope. This part is suitable for applications requiring increased current capacity. However, electrical life is reduced to 40,000 cycles, and ingress protection rating is not specified. ROHS3 compliance is confirmed. This alternative is appropriate for low-cycle-count applications or where higher voltage/current margins are required.

Similar Alternative - Electroswitch A223T1TCB: The A223T1TCB offers marginally higher current rating (0.5VA) and voltage rating (28V AC/DC) with RoHS compliance. Operating temperature extends to 90°C. Electrical life is 60,000 cycles. Panel cutout dimensions are not specified, requiring verification before mechanical integration. This part is suitable for applications with slightly elevated electrical requirements and extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the 7201TCWCPE22 be used as a direct replacement for the 7201TCWCKE22? A: Yes. The 7201TCWCPE22 maintains identical electrical ratings (0.4VA at 20V AC/DC), mechanical dimensions, circuit configuration (DPDT On-On), and mounting specifications. The primary difference is product status (Active vs. Obsolete) and terminal sealing improvement (epoxy sealed). This is the recommended direct substitute.

Q: What are the key differences between the direct equivalent and similar alternatives? A: The direct equivalent (7201TCWCPE22) preserves all electrical and mechanical specifications. Similar alternatives offer higher electrical ratings but with trade-offs: the Grayhill part provides 5A at 125V but reduces electrical life to 40,000 cycles; the Electroswitch part offers 0.5VA at 28V with 60,000 cycles. Both similar alternatives lack specified ingress protection ratings.

Q: Are the panel cutout dimensions identical across all substitute parts? A: The 7201TCWCKE22, 7201TCWCPE22, and 34ADP18T7M2QT all specify circular 11.91mm diameter cutouts with 15/32-32 bushing threads. The Electroswitch A223T1TCB does not specify panel cutout dimensions and requires verification before mechanical integration.

Q: What is the impact of reduced electrical life in the Grayhill alternative? A: The 34ADP18T7M2QT is rated for 40,000 cycles compared to the original 100,000 cycles. This reduction is acceptable for applications with infrequent switching operations but unsuitable for high-cycle-count environments. Verify application duty cycle before selection.

Q: Are RoHS compliance differences significant for part selection? A: The original 7201TCWCKE22 is RoHS non-compliant. The direct equivalent 7201TCWCPE22 and both similar alternatives are RoHS compliant or ROHS3 compliant. For applications subject to RoHS regulations, the compliant alternatives are required. For legacy systems without RoHS requirements, compliance status does not affect electrical or mechanical compatibility.

Q: Can these parts be used interchangeably in existing designs? A: The direct equivalent 7201TCWCPE22 is fully interchangeable. Similar alternatives require verification of application electrical requirements (current and voltage margins) and duty cycle (electrical life). Mechanical compatibility must be confirmed for the Electroswitch part due to unspecified panel cutout dimensions.
