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

Part Overview

The C&K 7201SPCWCBI is an active production toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features anti-rotation actuator design, IP67 ingress protection, and epoxy potting for enhanced durability. Substitute parts are identified when equivalent electrical ratings, mechanical mounting interfaces, and circuit configurations are required for design flexibility, inventory optimization, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SPCWCBI are qualified based on the following critical parameters that must align with the main part:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C

Allowable Variations:

• Actuator type and length (within mechanical compatibility)
• Electrical life cycles (provided minimum operational requirements are met)
• Ingress protection rating (equal or superior)
• Sealing method (epoxy potted vs. epoxy sealed terminals)
• Actuator material plating (brass chrome-plated vs. brass nickel-plated)

The following parts meet these substitution criteria: E-Switch 100AWDP1T1B1M2REH, E-Switch 100DP1T6B15M2RE, and TE Connectivity ALCOSWITCH 2-1825138-4. The E-Switch 100DP1T1B1M2QEH does not qualify as a direct substitute due to higher current rating (5A) and voltage specifications (120V AC/28V DC) that exceed the original design parameters.

Parameter Comparison

Engineering Selection Recommendations

All qualified substitute parts—E-Switch 100AWDP1T1B1M2REH, E-Switch 100DP1T6B15M2RE, and TE Connectivity ALCOSWITCH 2-1825138-4—maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original C&K 7201SPCWCBI.

The E-Switch 100AWDP1T1B1M2REH provides the closest electrical and mechanical equivalence with identical voltage and current ratings, matching panel cutout and bushing specifications. This part is suitable for direct substitution in applications where the 30,000-cycle electrical life meets operational requirements.

The E-Switch 100DP1T6B15M2RE offers equivalent electrical performance with a longer actuator length (12.30mm vs. 10.67mm). This dimensional difference requires mechanical clearance verification in panel-mount applications before selection.

The TE Connectivity ALCOSWITCH 2-1825138-4 meets all electrical and mechanical substitution criteria. However, the significantly lower electrical life rating (6,000 cycles vs. 100,000 cycles) restricts its application to low-cycle-count environments.

The E-Switch 100DP1T1B1M2QEH does not qualify as a substitute due to electrical parameter mismatch: 5A current rating and 120V AC/28V DC voltage specifications exceed the original design envelope.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH be used as a substitute for the C&K 7201SPCWCBI?

A: No. The 100DP1T1B1M2QEH has a current rating of 5A and voltage ratings of 120V AC/28V DC, which do not match the required 0.4VA at 20V AC/DC specification. Using this part would result in over-specification and potential circuit incompatibility.

Q: What is the primary difference between the E-Switch 100AWDP1T1B1M2REH and 100DP1T6B15M2RE?

A: Both parts meet the electrical requirements of the main part. The key difference is actuator design and length: the 100AWDP1T1B1M2REH uses a standard round actuator at 10.41mm length, while the 100DP1T6B15M2RE uses a flat anti-rotation actuator at 12.30mm length. Panel cutout clearance must be verified for the longer actuator.

Q: Does the lower electrical life of the TE Connectivity 2-1825138-4 affect its suitability as a substitute?

A: The 2-1825138-4 has an electrical life of 6,000 cycles compared to the original part's 100,000 cycles. This part is suitable only for applications with low switching frequency and cycle count requirements. High-cycle applications should use the E-Switch alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All qualified substitute parts—E-Switch 100AWDP1T1B1M2REH, E-Switch 100DP1T6B15M2RE, and TE Connectivity ALCOSWITCH 2-1825138-4—are ROHS3 compliant, matching the regulatory status of the original C&K 7201SPCWCBI.

Q: What packaging formats are available for these substitute parts?

A: The C&K 7201SPCWCBI is supplied in Tray packaging. Substitute parts are available in Bulk packaging: E-Switch 100AWDP1T1B1M2REH, E-Switch 100DP1T6B15M2RE, and TE Connectivity ALCOSWITCH 2-1825138-4. Packaging format differences do not affect electrical or mechanical compatibility.

Q: Can the actuator material difference (brass chrome-plated vs. brass nickel-plated) affect performance?

A: Both plating options provide corrosion resistance and durability within the specified operating temperature range. The material difference does not affect electrical performance or mechanical function in standard applications.
