C&K 7201P3HCQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P3HCQE 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 flat anti-rotation actuator, epoxy sealed terminals, and PC pin termination. Finding equivalent and substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7201P3HCQE is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters (Must Match):

• 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 to 85°C

Electrical Compatibility Parameters:

• Current rating: 5A (AC/DC)
• Voltage rating - AC: 120V
• Voltage rating - DC: 28V

The substitute parts listed have been evaluated against these parameters. Parts with reduced electrical ratings (0.4VA at 20V) or different actuator specifications represent functional alternatives for applications with lower electrical demands or different mechanical requirements, but do not provide direct equivalence to the main part's full electrical specification.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH provides the closest functional equivalence to the C&K 7201P3HCQE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), DPDT configuration, panel mount specifications, and operating temperature range. The primary differences are actuator geometry (standard round versus flat anti-rotation) and reduced electrical life (40,000 cycles versus 100,000 cycles). This part is ROHS3 compliant and REACH unaffected, offering regulatory advantages in certain supply chain contexts.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are suitable only for applications with reduced electrical requirements (0.4VA at 20V maximum). These parts maintain mechanical compatibility through identical panel cutout and bushing specifications but cannot support the full 5A/120V electrical specification of the main part. Both are ROHS3 compliant. The TE Connectivity part exhibits significantly lower electrical life (6,000 cycles) compared to the main part.

All substitute parts maintain ROHS3 compliance and are active production items, ensuring continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M2QEH be used as a direct replacement for C&K 7201P3HCQE?

A: Yes, for applications requiring 5A at 120V AC or 28V DC. Both parts share identical electrical ratings, DPDT configuration, and mechanical mounting specifications. The actuator type differs (standard round versus flat anti-rotation), which may affect panel aesthetics or specific mechanical constraints. Electrical life is reduced from 100,000 to 40,000 cycles.

Q: Why do E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 have lower electrical ratings?

A: These parts are designed for low-signal applications with maximum ratings of 0.4VA at 20V. They are not suitable for the 5A/120V specification of the main part. Selection of these parts requires confirmation that the application operates within their reduced electrical envelope.

Q: What is the impact of different actuator types?

A: The C&K 7201P3HCQE uses a flat anti-rotation actuator (11.43mm length), while E-Switch 100DP1T1B1M2QEH uses a standard round actuator (10.41mm length). Flat anti-rotation actuators prevent unintended rotation during installation. Standard round actuators may require additional mechanical retention in certain panel configurations. Verify panel design compatibility before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The C&K 7201P3HCQE is REACH affected, while E-Switch parts are REACH unaffected. TE Connectivity 2-1825138-4 is REACH affected. Verify regulatory requirements for your specific application and supply chain.

Q: What is the significance of electrical life differences?

A: The C&K 7201P3HCQE is rated for 100,000 cycles, while E-Switch alternatives are rated for 40,000 cycles, and TE Connectivity 2-1825138-4 is rated for 6,000 cycles. For applications with high switching frequency or extended operational life requirements, the higher cycle rating of the main part may be necessary. Evaluate expected switch actuation frequency against rated electrical life.

Q: Can packaging differences affect compatibility?

A: The C&K 7201P3HCQE is supplied in trays, while all substitute parts are supplied in bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical compatibility. Confirm packaging requirements with procurement specifications.
