C&K 7201SDZQES2 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SDZQES2 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a satin chrome actuator, solder lug termination, and operates across a temperature range of -30°C to 85°C with 100,000 electrical cycles rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SDZQES2 are grouped based on electrical and mechanical compatibility within the following allowed parameters:

Primary Substitution Criteria:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: Solder Lug
• Operating temperature range: -30°C to 85°C

Electrical Rating Groups:

Group 1 - Full Electrical Equivalents (5A @ 120V AC / 28V DC):

• E-Switch 100DP1T6B11M1QEH
• Grayhill Inc. 34ADP11B1M1GT
• Grayhill Inc. 34ADP13B1M1QT

Group 2 - Reduced Electrical Rating (0.4VA @ 20V AC/DC):

• E-Switch 100DP1T1B1M1REH
• E-Switch 100DP1T6B11M1REH
• Grayhill Inc. 34ADP11B9M1RT

Substitution within Group 1 maintains full electrical compatibility. Group 2 parts operate at reduced voltage and current ratings and are suitable only for applications with lower electrical requirements than the original specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Full Electrical Equivalence):

Select from Group 1 substitutes when the application requires 5A at 120V AC or 28V DC operation:

• E-Switch 100DP1T6B11M1QEH: Active product status with ROHS3 compliance and REACH unaffected designation
• Grayhill Inc. 34ADP11B1M1GT: Active product status with ROHS3 compliance and REACH unaffected designation
• Grayhill Inc. 34ADP13B1M1QT: Active product status with ROHS3 compliance and REACH unaffected designation

All Group 1 parts maintain mechanical and electrical compatibility with the original 7201SDZQES2 specification. Note that Group 1 substitutes are rated for 40,000 electrical cycles compared to the original part's 100,000 cycles.

For Reduced Electrical Requirement Applications:

Select from Group 2 substitutes only when the application operates at 0.4VA maximum at 20V AC or DC:

• E-Switch 100DP1T1B1M1REH: Active product status with ROHS3 compliance and REACH unaffected designation
• E-Switch 100DP1T6B11M1REH: Active product status with ROHS3 compliance and REACH unaffected designation
• Grayhill Inc. 34ADP11B9M1RT: Active product status with ROHS3 compliance and REACH unaffected designation

Group 2 parts are not suitable for applications requiring the original 5A/120V electrical rating.

Frequently Asked Questions (FAQ)

Q: Can I use a Group 2 substitute part in an application designed for the 7201SDZQES2?

A: No. Group 2 parts are rated for 0.4VA at 20V maximum, while the 7201SDZQES2 is rated for 5A at 120V AC. Using a Group 2 part in a 5A/120V application will result in switch failure. Group 2 parts are suitable only for low-voltage, low-current applications.

Q: What is the difference between the E-Switch and Grayhill substitute options?

A: Both manufacturers provide DPDT toggle switches with identical mechanical mounting specifications and operating temperature ranges. All Group 1 substitutes maintain the same electrical ratings (5A/120V AC, 28V DC). Selection between manufacturers can be based on availability, packaging preference (Bulk vs. Tray), or supply chain considerations.

Q: Why do the substitute parts have lower electrical life ratings (40,000 cycles vs. 100,000 cycles)?

A: The substitute parts are rated for 40,000 electrical cycles, which is lower than the original 7201SDZQES2 specification of 100,000 cycles. For applications requiring extended cycle life, this difference should be evaluated against the application's expected operational demands.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original 7201SDZQES2 is also ROHS3 compliant.

Q: What is the difference between the E-Switch 100DP1T6B11M1QEH and 100DP1T1B1M1REH?

A: The 100DP1T6B11M1QEH is a full electrical equivalent rated for 5A at 120V AC and 28V DC. The 100DP1T1B1M1REH is rated for reduced electrical requirements at 0.4VA at 20V AC/DC. These parts are not interchangeable for applications requiring the higher electrical rating.

Q: Can I use substitute parts with different actuator types?

A: Yes. The substitute parts include variations in actuator type (Standard Round vs. Flat Anti-Rotation) and actuator length. These mechanical differences do not affect electrical compatibility or panel mounting. Selection should be based on the specific mechanical requirements of your application's panel interface.
