C&K 7201SY4ZGE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SY4ZGE 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 is designed for applications requiring reliable on-on switching functionality. Substitute parts are identified to provide equivalent electrical performance and mechanical compatibility for applications where the original part is unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on electrical rating compatibility with the main part 7201SY4ZGE. The primary substitution criteria are:

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

• E-Switch 100DP1T4B1M1QEH
• E-Switch 100DP1T6B11M1QEH

These parts maintain identical electrical ratings and voltage specifications, differing only in actuator type and length. Both are suitable for direct substitution in applications requiring the full 5A/120V rating.

Reduced Rating Alternatives (0.4VA @ 20V AC/DC):

• E-Switch 100DP1T1B1M1REH
• E-Switch 100DP1T6B11M1REH

These parts are suitable only for applications with lower power requirements (0.4VA maximum at 20V). They share identical mechanical mounting characteristics but operate at reduced electrical capacity.

All substitute parts maintain DPDT on-on configuration, panel mount design, 6.35mm circular panel cutout, 1/4-40 bushing thread, solder lug termination, and -30°C to 85°C operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Full Electrical Equivalence (5A @ 120V AC / 28V DC Applications):

E-Switch 100DP1T4B1M1QEH and 100DP1T6B11M1QEH are direct electrical substitutes for the C&K 7201SY4ZGE. Both maintain identical voltage and current ratings. Selection between these two depends on actuator geometry requirements: 100DP1T4B1M1QEH provides a standard round actuator with 16.26mm length, while 100DP1T6B11M1QEH provides a flat anti-rotation actuator with 12.30mm length. Both are ROHS3 compliant and active production parts.

For Reduced Power Applications (0.4VA @ 20V AC/DC):

E-Switch 100DP1T1B1M1REH and 100DP1T6B11M1REH are suitable only for applications with maximum power requirements of 0.4VA at 20V. These parts are not suitable for applications requiring the full 5A/120V rating of the original part. Selection between these two depends on actuator type: 100DP1T1B1M1REH features a standard round actuator with 10.41mm length, while 100DP1T6B11M1REH features a flat anti-rotation actuator with 12.30mm length.

All substitute parts are ROHS3 compliant, active production items, and maintain mechanical compatibility through identical panel cutout dimensions and bushing thread specifications.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T4B1M1QEH be used as a direct replacement for C&K 7201SY4ZGE?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC and 28V DC), DPDT on-on configuration, panel mount design, and solder lug termination. The primary difference is actuator length (16.26mm versus 10.67mm), which must be verified for panel clearance in the application.

Q: What is the difference between the two 5A/120V E-Switch substitutes?

A: E-Switch 100DP1T4B1M1QEH features a standard round actuator with 16.26mm length. E-Switch 100DP1T6B11M1QEH features a flat anti-rotation actuator with 12.30mm length. Both maintain identical electrical ratings and mechanical mounting specifications. Selection depends on actuator type and length requirements for the specific application.

Q: Can the 0.4VA E-Switch parts replace the C&K 7201SY4ZGE in all applications?

A: No. The 0.4VA E-Switch parts (100DP1T1B1M1REH and 100DP1T6B11M1REH) are suitable only for applications with maximum power requirements of 0.4VA at 20V. They cannot be used in applications requiring the full 5A/120V rating of the original part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the C&K 7201SY4ZGE.

Q: What is the difference in electrical life between the main part and substitutes?

A: The C&K 7201SY4ZGE is rated for 100,000 electrical cycles. All E-Switch substitute parts are rated for 40,000 electrical cycles. Applications requiring extended cycle life should account for this difference.

Q: Do all parts use the same termination style?

A: Yes. The main part and all substitute parts use solder lug termination, ensuring compatibility with existing PCB layouts and wiring harnesses.
