C&K 7201SH3CBE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SH3CBE is an active-status panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This switch is designed for applications requiring reliable on-on switching functionality with epoxy-sealed terminals and a standard round actuator. Substitute parts are identified to provide equivalent electrical and mechanical performance for applications where the original part is unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SH3CBE are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit Configuration: DPDT (required match)
• Switch Function: On-On (required match)
• Current Rating: 0.4VA AC/DC (required match for direct substitution)
• Voltage Rating: 20V AC and 20V DC (required match for direct substitution)
• Mounting Type: Panel Mount (required match)
• Panel Cutout Dimensions: Circular 6.35mm Dia (required match)
• Bushing Thread: 1/4-40 (required match)
• Termination Style: PC Pin (required match)
• Operating Temperature: -30°C to 85°C (required match)

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents. Parts with variations in non-critical parameters (such as actuator length, actuator type, or electrical life) are noted for application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct substitution with the C&K 7201SH3CBE. Selection among these equivalents should be based on the following factors:

100AWDP1T1B1M2REH (E-Switch): This part provides direct electrical equivalence with identical current and voltage ratings. It includes IP67 ingress protection (dust tight, waterproof), which exceeds the base specification. Actuator length is 10.41mm, representing a 0.25mm increase from the original. Electrical life is rated at 30,000 cycles. REACH status is unaffected.

100DP1T6B15M2RE (E-Switch): This part maintains electrical equivalence but features a flat anti-rotation actuator type, differing from the standard round actuator of the original part. Actuator length is 12.30mm, a 2.14mm increase. Electrical life is rated at 40,000 cycles. This configuration is suitable for applications requiring actuator anti-rotation properties.

2-1825138-4 (TE Connectivity ALCOSWITCH Switches): This part provides electrical equivalence with identical current and voltage ratings. Actuator length is 10.41mm. Electrical life is rated at 6,000 cycles, significantly lower than the original specification. Actuator material is brass with nickel plating, differing from the chrome-plated material of the original. REACH status is affected.

All substitute parts are ROHS3 compliant and active-status products. Selection should account for application-specific requirements regarding electrical life cycles, actuator geometry, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100AWDP1T1B1M2REH be used as a direct replacement for the C&K 7201SH3CBE?

A: Yes. Both parts share identical electrical specifications (0.4VA, 20V AC/DC, DPDT, On-On), mounting configuration (panel mount, 6.35mm circular cutout, 1/4-40 bushing thread), and termination style (PC pin). The E-Switch part includes additional IP67 ingress protection and operates within the same temperature range. Actuator length differs by 0.25mm (10.41mm vs. 10.16mm), which is negligible for most panel-mount applications.

Q: What is the key difference between the E-Switch 100DP1T6B15M2RE and the original C&K part?

A: The primary difference is the actuator type. The E-Switch part features a flat anti-rotation actuator, whereas the C&K part uses a standard round actuator. Both maintain identical electrical ratings and mounting specifications. The flat anti-rotation design prevents unintended rotation of the actuator. Actuator length is 12.30mm, compared to 10.16mm on the original part.

Q: Why does the TE Connectivity 2-1825138-4 have a lower electrical life rating?

A: The TE Connectivity part is rated for 6,000 electrical cycles, compared to 100,000 cycles for the C&K original and higher ratings for E-Switch alternatives. This specification reflects the design characteristics of the Gemini A series. Applications requiring extended cycle life should prioritize parts with higher electrical life ratings.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the C&K 7201SH3CBE, are ROHS3 compliant. This certification applies uniformly across all options presented.

Q: What packaging formats are available for these parts?

A: The C&K 7201SH3CBE is supplied in tray packaging. All E-Switch and TE Connectivity substitute parts are supplied in bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.

Q: Does the IP67 rating on the E-Switch 100AWDP1T1B1M2REH affect compatibility?

A: No. The IP67 ingress protection rating (dust tight, waterproof) on the E-Switch part represents an enhancement to the base specification. It does not affect electrical or mechanical compatibility with applications designed for the original C&K part. Applications in sealed or wet environments may benefit from this additional protection.
