C&K 7201SY4ZQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SY4ZQE is an active production toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with solder lug termination and epoxy sealed terminals for enhanced reliability. The part is ROHS3 compliant and maintains an operating temperature range of -30°C to 85°C with 100,000 electrical life cycles.

Equivalent and substitute parts are identified when design requirements permit relaxation of specific electrical or mechanical parameters while maintaining core functional compatibility within the DPDT panel-mount switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 7201SY4ZQE is based on the following criteria:

Primary Substitutes (Full Electrical Equivalence):

• E-Switch 100DP1T4B1M1QEH and 100DP1T6B11M1QEH maintain identical electrical ratings: 5A at 120V AC and 28V DC
• Both parts share DPDT On-On configuration, panel-mount design, 6.35mm circular cutout, 1/4-40 bushing thread, and solder lug termination
• Mechanical differences are limited to actuator type and length, which do not affect electrical substitution when panel geometry permits

Secondary Substitutes (Reduced Electrical Rating):

• E-Switch 100DP1T1B1M1REH and 100DP1T6B11M1REH are rated for 0.4VA at 20V AC/DC
• These parts are suitable only for applications with lower voltage and current requirements than the original specification
• Mechanical compatibility remains identical (panel cutout, bushing thread, termination style)

All substitute parts are ROHS3 compliant, feature epoxy sealed terminals, and operate within the -30°C to 85°C temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Full Electrical Equivalence: Select E-Switch 100DP1T4B1M1QEH or 100DP1T6B11M1QEH when the application requires 5A at 120V AC or 28V DC with DPDT On-On functionality. Both parts maintain identical electrical specifications to the 7201SY4ZQE. The choice between these two depends on actuator geometry requirements: 100DP1T4B1M1QEH features a standard round actuator at 16.26mm length, while 100DP1T6B11M1QEH provides a flat anti-rotation actuator at 12.30mm length. Both are ROHS3 compliant and active production parts.

For Reduced Electrical Rating Applications: Select E-Switch 100DP1T1B1M1REH or 100DP1T6B11M1REH only when application voltage and current requirements do not exceed 0.4VA at 20V AC/DC. These parts are suitable for low-power signal switching applications. Actuator selection follows the same logic: standard round at 10.41mm (100DP1T1B1M1REH) or flat anti-rotation at 12.30mm (100DP1T6B11M1REH).

All substitute parts are ROHS3 compliant and maintain active production status. Panel mounting geometry is identical across all options.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T4B1M1QEH directly replace the C&K 7201SY4ZQE?

A: Yes, for electrical functionality. Both parts are rated 5A at 120V AC and 28V DC with DPDT On-On configuration. The primary difference is actuator length (16.26mm versus 10.67mm). Verify that panel geometry and actuator clearance accommodate the longer actuator before substitution.

Q: What is the difference between the two E-Switch high-current options?

A: E-Switch 100DP1T4B1M1QEH and 100DP1T6B11M1QEH are electrically identical (5A at 120V AC/28V DC). The difference is actuator type: 100DP1T4B1M1QEH has a standard round actuator at 16.26mm, while 100DP1T6B11M1QEH has a flat anti-rotation actuator at 12.30mm. Select based on panel design and actuator engagement requirements.

Q: Can I use the E-Switch 100DP1T1B1M1REH in a 120V application?

A: No. The 100DP1T1B1M1REH is rated for 20V AC/DC maximum. Using it in a 120V application exceeds its electrical rating and will result in component failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (100DP1T4B1M1QEH, 100DP1T6B11M1QEH, 100DP1T1B1M1REH, 100DP1T6B11M1REH) are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What is the impact of reduced electrical life cycles in substitute parts?

A: The C&K 7201SY4ZQE is rated for 100,000 electrical cycles, while all E-Switch substitutes are rated for 40,000 cycles. For applications requiring extended cycle life, the original C&K part is recommended. For standard industrial applications, the 40,000-cycle rating of E-Switch parts is typically sufficient.

Q: Do all parts use the same panel cutout and bushing thread?

A: Yes. All parts feature a 6.35mm diameter circular panel cutout and 1/4-40 bushing thread, ensuring mechanical compatibility in panel-mount installations.
