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

Part Overview

The C&K 7201SYCQI is an active production toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with epoxy potting and is designed for general-purpose switching applications requiring reliable electrical performance across industrial and commercial environments. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where alternative electrical or mechanical specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7201SYCQI is determined by strict alignment of core electrical and mechanical parameters. All substitute parts must maintain identical circuit configuration (DPDT), switch function (On-On), mounting type (Panel Mount), termination style (PC Pin), and panel interface dimensions (6.35mm circular cutout with 1/4-40 bushing thread).

Substitute parts are grouped into two categories based on electrical rating compatibility:

Category A - Full Electrical Equivalents: Parts maintaining the 5A current rating at 120V AC and 28V DC specifications. These parts are direct functional replacements with no derating required.

Category B - Reduced Electrical Rating: Parts with lower current ratings (0.4VA at 20V AC/DC). These parts are suitable only for applications where the lower electrical specifications meet design requirements and do not exceed the substitute part's ratings.

All substitute parts must maintain ROHS3 compliance, PC Pin termination, and compatible panel mounting geometry to ensure mechanical and electrical interchangeability within their respective rating categories.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH is the primary substitute for the C&K 7201SYCQI. This part maintains full electrical equivalence with identical 5A current rating at 120V AC and 28V DC. All mechanical parameters including panel cutout dimensions, bushing thread specification, and PC Pin termination are identical. The part is active in production with ROHS3 compliance. The actuator length variance of 0.26mm is within acceptable mechanical tolerance for panel-mount applications. Electrical life rating of 40,000 cycles is lower than the original part; applications requiring extended cycle life should account for this difference.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are suitable only for applications where electrical specifications do not exceed 0.4VA at 20V AC/DC. These parts feature reduced current and voltage ratings and are not suitable for replacement in circuits designed for the original 5A/120V AC specification. Both parts maintain mechanical compatibility with identical panel cutout and bushing thread dimensions. The E-Switch part features a flat anti-rotation actuator with increased length of 12.30mm; verify panel clearance before selection. The TE Connectivity part exhibits significantly lower electrical life at 6,000 cycles and should be evaluated for duty cycle requirements.

All substitute parts maintain ROHS3 compliance and are active in production status, ensuring continued availability and regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M2QEH be used as a direct replacement for C&K 7201SYCQI?

A: Yes. The E-Switch 100DP1T1B1M2QEH maintains identical electrical ratings (5A at 120V AC/28V DC), circuit configuration (DPDT), switch function (On-On), and mechanical interface (6.35mm panel cutout, 1/4-40 bushing, PC Pin termination). The actuator length difference of 0.26mm is within acceptable tolerance for panel-mount applications. Verify panel clearance and confirm that the 40,000-cycle electrical life meets application requirements.

Q: Why are E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 listed as substitutes if they have lower electrical ratings?

A: These parts are listed as substitutes for applications where the reduced electrical specifications (0.4VA at 20V AC/DC) are acceptable and do not exceed circuit design requirements. They maintain mechanical compatibility through identical panel cutout dimensions and bushing thread specification. These parts are not suitable for circuits designed for the original 5A/120V AC rating.

Q: What is the impact of different electrical life ratings among substitute parts?

A: Electrical life indicates the number of switching cycles a part can withstand before performance degradation. The C&K 7201SYCQI is rated for 100,000 cycles, while E-Switch substitutes are rated for 40,000 cycles, and the TE Connectivity part for 6,000 cycles. Applications with high switching frequency or extended operational life should account for these differences in component selection and maintenance planning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with the original C&K 7201SYCQI component.

Q: What is the difference between the actuator types in the substitute parts?

A: The C&K 7201SYCQI and E-Switch 100DP1T1B1M2QEH feature standard round actuators. The E-Switch 100DP1T6B15M2RE features a flat anti-rotation actuator with increased length (12.30mm versus 10.67mm). Verify panel cutout clearance and actuator engagement depth before selecting the flat anti-rotation variant.

Q: Do packaging differences affect component compatibility?

A: Packaging format (Tray versus Bulk) does not affect electrical or mechanical compatibility. Packaging differences relate to supply chain logistics and inventory management. Select based on procurement requirements and quantity needs.
