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

Part Overview

The C&K 7201SCWCKE 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 identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The switch features epoxy-sealed terminals, IP67 ingress protection, and operates across -30°C to 85°C, suitable for industrial and sealed enclosure applications.

Substitute Part Grouping Explanation

Substitute parts for the 7201SCWCKE are classified into two categories based on electrical and mechanical compatibility:

Direct Manufacturer Substitute (Recommended Primary Alternative): The 7201SCWCPE from C&K maintains identical electrical specifications (0.4VA, 20V AC/DC), mechanical form factor (panel mount, 1/4-40 bushing, 6.35mm circular cutout), and functional characteristics (DPDT, On-On, 100,000 cycle life). The primary distinction is product status (Active vs. Obsolete) and regulatory compliance (RoHS Compliant vs. Non-Compliant). This part is the direct successor within the same 7000 series.

Similar Manufacturer Substitute (Functional Alternative): The Electroswitch A223S1YCB provides functional equivalence with relaxed electrical parameters. It maintains DPDT configuration, On-On function, panel-mount design, and PC pin termination. However, it operates at higher voltage ratings (0.5VA, 28V AC/DC), features a slightly shorter actuator (10.41mm vs. 10.67mm), and delivers reduced electrical life (60,000 vs. 100,000 cycles). This part is suitable only when application voltage and current requirements do not exceed 0.5VA at 28V.

Key Parameters Determining Substitution:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Voltage and current ratings (must meet or exceed application requirements)
• Operating temperature range (must encompass application environment)

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Maintenance Applications: The C&K 7201SCWCPE is the primary substitute for the obsolete 7201SCWCKE. Both parts maintain identical electrical ratings (0.4VA, 20V AC/DC), mechanical interfaces, and functional performance (100,000 cycle life). The 7201SCWCPE carries Active product status and RoHS Compliant certification, making it suitable for modern procurement and regulatory compliance requirements.

For Applications with Elevated Voltage/Current Tolerance: The Electroswitch A223S1YCB may be selected when application requirements permit operation at higher voltage ratings (28V AC/DC) and current capacity (0.5VA). This part is RoHS Compliant and maintains panel-mount compatibility. Selection of this part requires verification that the application environment does not exceed the reduced electrical life specification (60,000 cycles vs. 100,000 cycles).

Regulatory Compliance Considerations: The 7201SCWCKE is RoHS Non-Compliant. Both substitute parts (7201SCWCPE and A223S1YCB) are RoHS Compliant, supporting compliance with modern regulatory frameworks. The 7201SCWCPE carries REACH Affected status, while the A223S1YCB status is Vendor Undefined.

Frequently Asked Questions (FAQ)

Q: Can the 7201SCWCPE directly replace the 7201SCWCKE without circuit modification? A: Yes. The 7201SCWCPE maintains identical electrical ratings (0.4VA, 20V AC/DC), DPDT configuration, On-On function, and mechanical form factor (panel mount, 1/4-40 bushing, 6.35mm circular cutout). No circuit or mechanical redesign is required.

Q: What are the limitations of using the Electroswitch A223S1YCB as a substitute? A: The A223S1YCB operates at higher voltage ratings (28V vs. 20V) and current capacity (0.5VA vs. 0.4VA), but delivers reduced electrical life (60,000 cycles vs. 100,000 cycles). It is suitable only for applications where the lower cycle life does not compromise system reliability and where voltage/current requirements do not exceed the 7201SCWCKE specification.

Q: Are there mechanical compatibility concerns when substituting these parts? A: All three parts share identical panel-mount interfaces: 1/4-40 bushing thread, 6.35mm circular panel cutout, and PC pin termination. The Electroswitch A223S1YCB features a slightly shorter actuator (10.41mm vs. 10.67mm), which may affect tactile feel but does not prevent mechanical installation.

Q: What is the inventory status for these substitute parts? A: The 7201SCWCKE (obsolete) has 805 units in stock. The 7201SCWCPE (direct substitute) has 808 units in stock. The A223S1YCB has 796 units in stock. Inventory availability should be confirmed at time of procurement.

Q: Does the RoHS compliance difference affect part selection? A: The 7201SCWCKE is RoHS Non-Compliant, while both substitutes are RoHS Compliant. For applications subject to RoHS regulations or modern procurement standards, the 7201SCWCPE is the appropriate selection. The A223S1YCB is also RoHS Compliant but carries different electrical specifications.

Q: What operating temperature range should be considered for substitution? A: The 7201SCWCKE and 7201SCWCPE both operate across -30°C to 85°C. The A223S1YCB extends to -30°C to 90°C, providing a 5°C higher upper limit. For applications operating near the 85°C boundary, the A223S1YCB offers additional thermal margin.
