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

Part Overview

The C&K 7201SYCSE is an active-status 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-sealed PC pin termination and is designed for applications requiring reliable switching across industrial and commercial environments. Equivalent and substitute parts are identified based on matching circuit topology, electrical ratings, mechanical interface, and termination standards to ensure direct functional replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SYCSE are grouped based on electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

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

• Parts matching the 5A current rating and 120V AC / 28V DC voltage specifications with identical DPDT On-On configuration and panel-mount interface qualify as direct electrical substitutes.

Reduced-Rating Substitutes (0.4VA/20V AC/DC):

• Parts with lower current and voltage ratings (0.4VA at 20V AC/DC) maintain DPDT On-On topology and panel-mount mechanical interface but are suitable only for applications within their reduced electrical envelope.

Mechanical Compatibility Criteria:

• Panel cutout diameter: 6.35mm (circular)
• Bushing thread: 1/4-40
• Termination: PC Pin
• Mounting: Panel Mount
• Operating temperature: -30°C to 85°C

All substitute parts listed maintain these mechanical and interface specifications, ensuring physical and electrical compatibility within their respective electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent: The E-Switch 100DP1T1B1M2QEH provides full electrical equivalence to the 7201SYCSE, matching the 5A current rating and 120V AC / 28V DC voltage specifications. Both parts maintain ROHS3 compliance and active product status. The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles), which must be evaluated against application duty cycle requirements.

Same-Manufacturer Reduced-Rating Alternative: The C&K 7201SYCBE maintains manufacturer continuity and identical mechanical interface with the 7201SYCSE but operates at reduced electrical ratings (0.4VA at 20V AC/DC). This part is suitable only for low-power switching applications within its specified voltage and current envelope. Electrical life remains at 100,000 cycles.

Cross-Manufacturer Reduced-Rating Alternatives: The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 both provide DPDT On-On switching at 0.4VA / 20V ratings with panel-mount compatibility. The E-Switch part features a flat anti-rotation actuator (12.30mm length) and 40,000-cycle life. The TE Connectivity part uses a standard round actuator (10.41mm length) with reduced electrical life (6,000 cycles) and nickel-plated actuator material.

All substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 7201SYCBE substitute for the 7201SYCSE in all applications? A: The 7201SYCBE is mechanically and functionally compatible but operates at reduced electrical ratings (0.4VA / 20V versus 5A / 120V). Substitution is valid only for applications operating within the 0.4VA / 20V envelope. Applications requiring 5A at 120V must use the E-Switch 100DP1T1B1M2QEH or equivalent full-rating substitute.

Q: What is the primary difference between the E-Switch 100DP1T1B1M2QEH and the original 7201SYCSE? A: Both parts provide identical electrical ratings (5A / 120V AC, 28V DC) and mechanical interface. The E-Switch part has reduced electrical life (40,000 cycles versus 100,000 cycles). Selection depends on application cycle count requirements.

Q: Are all substitute parts panel-mount compatible with the original 7201SYCSE installation? A: Yes. All substitute parts maintain the 6.35mm circular panel cutout, 1/4-40 bushing thread, and PC pin termination. Mechanical installation compatibility is assured. Actuator length variations (10.41mm to 12.30mm) may affect panel clearance in confined spaces.

Q: Which substitute part has the longest electrical life? A: The C&K 7201SYCBE and original 7201SYCSE both provide 100,000-cycle electrical life. The E-Switch parts offer 40,000 cycles, and the TE Connectivity part offers 6,000 cycles.

Q: Can reduced-rating parts (0.4VA / 20V) be used in applications designed for 5A / 120V? A: No. Reduced-rating parts must operate within their specified electrical envelope. Using them in higher-voltage or higher-current applications will result in switch failure or unsafe operation.

Q: What is the difference between the E-Switch 100DP1T6B15M2RE and other reduced-rating substitutes? A: The 100DP1T6B15M2RE features a flat anti-rotation actuator (12.30mm length) versus standard round actuators in other parts. This design prevents unintended rotation but requires additional panel clearance. Electrical life is 40,000 cycles.
