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

Part Overview

The C&K 7201MYCBE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This switch is designed for On-On applications requiring low-voltage switching with epoxy-sealed terminals and a circular 6.35mm panel cutout. The part is Active status and ROHS3 compliant, making it suitable for applications requiring environmental compliance. Substitute parts may be required due to inventory constraints, application-specific voltage or current requirements, or termination style preferences.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Actuator type must be Standard Round
• Actuator length must be 5.08mm

Secondary Compatibility Criteria (Application-Dependent):

• Current rating must equal or exceed 0.4VA
• Voltage rating (AC and DC) must equal or exceed 20V
• Operating temperature range must encompass -30°C ~ 85°C
• Termination style compatibility with circuit board design
• RoHS and REACH compliance status for regulatory requirements

Two substitute parts meet the primary compatibility criteria with variations in secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

100DP1T2B3M2REH (E-Switch Series 100): This substitute provides electrical and mechanical equivalence to the 7201MYCBE. Both parts share identical current rating (0.4VA), voltage rating (20V AC/DC), termination style (PC Pin), and operating temperature range. The E-Switch part is ROHS3 compliant and Active status. The primary difference is electrical life rating (40,000 cycles versus 100,000 cycles), which should be evaluated against application duty cycle requirements. This substitute is suitable for direct replacement in equivalent circuit designs.

1-1825138-4 (TE Connectivity Gemini A Series): This substitute meets all primary mechanical compatibility criteria but differs significantly in electrical ratings. The TE Connectivity part is rated for 5A at 120V AC and 28V DC, exceeding the 7201MYCBE specifications. Termination style differs (Solder Lug versus PC Pin), requiring circuit board design modification. Electrical life is substantially lower (6,000 cycles). This substitute is suitable only for applications where higher voltage and current capacity are required and where solder lug termination is compatible with the circuit design. ROHS3 compliance and Active status are maintained.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T2B3M2REH directly replace the 7201MYCBE without circuit modification?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), mechanical dimensions (6.35mm panel cutout, 1/4-40 bushing thread), and termination style (PC Pin). Direct substitution is mechanically and electrically compatible. Electrical life difference (40,000 versus 100,000 cycles) should be considered for high-cycle applications.

Q: Can the 1-1825138-4 be used as a direct replacement?

A: No direct replacement without modification. The TE Connectivity part uses Solder Lug termination instead of PC Pin, requiring circuit board redesign. However, it is mechanically compatible for panel mounting. Use this substitute only when higher voltage (120V AC) and current (5A) capacity are required and circuit design permits solder lug connection.

Q: What are the key parameters that must match for substitution?

A: Circuit configuration (DPDT), switch function (On-On), mounting type (Panel Mount), panel cutout diameter (6.35mm), bushing thread (1/4-40), actuator type (Standard Round), and actuator length (5.08mm) must remain constant. Voltage and current ratings must meet or exceed application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both substitute parts (100DP1T2B3M2REH and 1-1825138-4) are ROHS3 compliant, matching the compliance status of the 7201MYCBE.

Q: What is the difference in electrical life between these parts?

A: The 7201MYCBE is rated for 100,000 cycles, the 100DP1T2B3M2REH for 40,000 cycles, and the 1-1825138-4 for 6,000 cycles. Select based on application duty cycle requirements.

Q: Does packaging type affect substitution compatibility?

A: No. Packaging (Tray versus Bulk) affects logistics and handling but does not impact electrical or mechanical compatibility. All parts are functionally equivalent within their respective parameter specifications.
