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

Part Overview

The C&K 7201TPCKE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 0.4VA at 20V AC/DC. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The switch features anti-rotation actuator design, epoxy sealed terminals, and PC pin termination suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Bushing thread: 15/32-32
• Actuator length: 17.45mm
• Current rating: Minimum 0.4VA (AC/DC)
• Voltage rating: Minimum 20V (AC/DC)
• Operating temperature range: Must encompass -30°C to 85°C
• Features: Epoxy sealed terminals

Substitutes are classified into two categories:

Direct Substitute (Same Manufacturer): Parts from C&K that maintain identical electrical and mechanical specifications while offering improved product status or compliance.

Similar Substitute (Alternative Manufacturer): Parts from other manufacturers that meet or exceed the core electrical and mechanical requirements, though with potential variations in non-critical parameters.

Engineering Selection Recommendations

7201TPCPE (Direct Substitute - Recommended for Compliance-Driven Applications)

The C&K 7201TPCPE is the primary substitute for the obsolete 7201TPCKE. This part maintains identical electrical specifications (0.4VA, 20V AC/DC), mechanical configuration (DPDT, On-On, panel mount), and actuator geometry (17.45mm anti-rotation). The 7201TPCPE is classified as active product status with RoHS compliance and REACH affected designation, making it suitable for applications requiring modern regulatory alignment. Inventory availability is confirmed at 945 pieces.

A223T1TCB (Similar Substitute - Alternative for Higher Voltage/Current Margin Applications)

The Electroswitch A223T1TCB provides functional equivalence with enhanced electrical ratings (0.5VA, 28V AC/DC) and extended operating temperature range (-30°C to 90°C). This part maintains DPDT configuration, On-On function, panel mount design, and PC pin termination with matching bushing thread specification. The primary mechanical difference is standard round actuator type versus anti-rotation design. Electrical life is rated at 60,000 cycles compared to 100,000 cycles for the main part. This substitute is suitable when higher voltage/current margins are beneficial and actuator type flexibility exists. RoHS compliance is confirmed; REACH status is vendor undefined.

Frequently Asked Questions (FAQ)

Q: Can the 7201TPCPE directly replace the 7201TPCKE without circuit modification?

A: Yes. The 7201TPCPE maintains identical DPDT configuration, voltage ratings (20V AC/DC), current rating (0.4VA), and mechanical specifications including panel cutout dimensions (11.91mm circular), bushing thread (15/32-32), and actuator length (17.45mm). No circuit redesign is required.

Q: What is the primary advantage of selecting 7201TPCPE over the obsolete 7201TPCKE?

A: The 7201TPCPE is active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and system updates. The obsolete 7201TPCKE presents supply chain risk and does not meet modern environmental compliance requirements.

Q: Is the A223T1TCB suitable for applications originally designed for the 7201TPCKE?

A: The A223T1TCB meets core functional requirements (DPDT, On-On, 0.5VA minimum, 28V minimum, panel mount, PC pin termination, 15/32-32 bushing thread). However, the actuator type differs (standard round versus anti-rotation), and electrical life is reduced to 60,000 cycles. Selection depends on whether anti-rotation functionality is critical to the application and whether 60,000-cycle life is acceptable.

Q: What is the significance of the anti-rotation actuator in the 7201TPCKE?

A: Anti-rotation actuator design prevents unintended rotation of the toggle lever during installation or vibration exposure. The A223T1TCB uses standard round actuator type, which does not include this feature. Applications requiring vibration resistance or installation torque control should prioritize the 7201TPCPE to maintain anti-rotation functionality.

Q: Are there packaging differences between these substitutes?

A: The 7201TPCKE and 7201TPCPE packaging specifications are not provided in the technical data. The A223T1TCB is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before final selection.

Q: What compliance certifications apply to each part?

A: The 7201TPCKE is RoHS non-compliant. The 7201TPCPE is RoHS compliant with REACH affected status. The A223T1TCB is RoHS compliant with vendor-undefined REACH status. All three parts carry EAR99 ECCN classification and 8536.50.9065 HTSUS code.

Q: Which substitute offers the longest electrical life?

A: Both the 7201TPCKE and 7201TPCPE are rated for 100,000 electrical cycles. The A223T1TCB is rated for 60,000 cycles, representing a 40% reduction in cycle life. Applications with high switching frequency should prioritize the 7201TPCPE.
