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

Part Overview

The C&K 7201SHCGE 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 sealed terminals and is designed for general-purpose switching applications requiring reliable electrical performance across industrial and commercial environments.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for alternative electrical or mechanical specifications within acceptable operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SHCGE is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• 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: PC Pin
• Operating temperature range: -30°C ~ 85°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: May be equal to or greater than 5A
• Voltage rating (AC): May be equal to or greater than 120V
• Voltage rating (DC): May be equal to or greater than 28V
• Actuator type: Standard Round or equivalent mechanical configurations
• Actuator length: Minor variations acceptable within mechanical constraints
• Electrical life cycles: May be lower or higher than 100,000 cycles
• Manufacturer: Different manufacturers permitted if all mandatory parameters align

The substitute parts listed below meet these criteria with documented variations noted in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Full Electrical Compatibility): The E-Switch 100DP1T1B1M2QEH provides direct electrical equivalence to the 7201SHCGE with identical current and voltage ratings (5A at 120V AC / 28V DC). Both parts maintain ROHS3 compliance and active production status. The minor actuator length difference (10.41mm vs 10.67mm) falls within acceptable mechanical tolerances for standard panel-mount applications. This substitute is suitable for applications where the full 5A electrical capacity is required.

Reduced Electrical Rating Substitutes: The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 both operate at reduced electrical ratings (0.4VA at 20V AC/DC). These parts are suitable only for applications where the circuit load does not exceed 0.4VA and operating voltages remain at or below 20V. The TE Connectivity part exhibits significantly lower electrical life (6,000 cycles vs 100,000 cycles) and should be evaluated for duty cycle requirements. The E-Switch 100DP1T6B15M2RE features a flat anti-rotation actuator, which may provide enhanced mechanical stability in high-vibration environments compared to the standard round actuator.

All substitute parts maintain ROHS3 compliance, active production status, and identical mechanical mounting specifications (panel cutout, bushing thread, termination style).

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH directly replace the C&K 7201SHCGE without circuit modification?

A: Yes. The 100DP1T1B1M2QEH matches all mandatory electrical and mechanical parameters. The 5A current rating at 120V AC and 28V DC is identical, panel mounting dimensions are equivalent, and both parts use PC pin termination. No circuit redesign is required.

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

A: These parts meet all mandatory mechanical and circuit configuration requirements (DPDT, On-On, panel mount, identical cutout and thread specifications). They are valid substitutes only for applications where the circuit load does not exceed 0.4VA and operating voltages remain at 20V or below. Applications requiring the full 5A capacity must use the 100DP1T1B1M2QEH.

Q: What is the significance of the different electrical life ratings?

A: Electrical life indicates the number of switching cycles the part can withstand before performance degradation. The 7201SHCGE is rated for 100,000 cycles, the E-Switch parts for 40,000 cycles, and the TE Connectivity part for 6,000 cycles. Selection should account for the application's duty cycle requirements. High-frequency switching applications may require the higher cycle rating of the primary part.

Q: Are there packaging differences between these parts?

A: Yes. The 7201SHCGE is supplied in Tray packaging, while all substitute parts are supplied in Bulk packaging. Procurement and inventory management processes may require adjustment to accommodate bulk packaging formats.

Q: Do all substitute parts maintain the same environmental compliance?

A: All parts are ROHS3 compliant and rated for -30°C to 85°C operation. The 7201SHCGE and E-Switch parts are REACH Affected or Unaffected as specified. The TE Connectivity 2-1825138-4 is REACH Affected. Compliance documentation should be verified for specific regulatory requirements in the end application.

Q: What is the impact of the different actuator types on mechanical performance?

A: The 7201SHCGE and most substitutes use a standard round actuator. The E-Switch 100DP1T6B15M2RE uses a flat anti-rotation design, which provides enhanced resistance to unintended actuation in high-vibration environments. Actuator length variations (10.41mm to 12.30mm) are minor and typically do not affect panel-mount installation, though clearance should be verified in space-constrained applications.
