C&K 7201P3HCKE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P3HCKE is a panel-mounted toggle switch with DPDT (Double Pole Double Throw) configuration rated for 0.4VA at 20V AC/DC. This component features a flat anti-rotation actuator, epoxy sealed terminals, and PC pin termination suitable for industrial control and instrumentation applications. The 7201P3HCKE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201P3HCKE are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitutability are:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Mechanical interface (Panel cutout 6.35mm diameter, 1/4-40 bushing thread)
• Actuator length (11.43mm)
• Termination style (PC Pin)
• Operating temperature range (-30°C ~ 85°C)

Substitute parts are grouped into two categories:

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

Similar Manufacturer Substitute: Parts from alternative manufacturers (Grayhill Inc.) that match all critical electrical and mechanical parameters, enabling cross-manufacturer compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer):

The C&K 7201P3HCPE is the primary substitute for the obsolete 7201P3HCKE. Both parts share identical electrical ratings, mechanical interfaces, and actuator specifications. The 7201P3HCPE offers the advantage of active product status and RoHS compliance, making it suitable for new designs and systems requiring regulatory adherence. The transition from the non-compliant 7201P3HCKE to the compliant 7201P3HCPE requires no circuit modifications.

For Cross-Manufacturer Substitution:

The Grayhill Inc. 34ADP16T2M2RT provides electrical and mechanical compatibility with identical voltage, current, and panel mounting specifications. This part is RoHS compliant and maintains the same operating temperature range. The primary consideration is the reduced electrical life rating of 40,000 cycles compared to the 100,000 cycles of the C&K parts. This difference is relevant only for applications requiring extended cycle life specifications. The actuator type differs slightly (Flatted versus Flat Anti-Rotation), though both maintain the same 11.43mm length and mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the 7201P3HCPE directly replace the 7201P3HCKE without circuit modifications?

A: Yes. The 7201P3HCPE maintains identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (DPDT On-On), and mechanical interface (panel cutout 6.35mm diameter, 1/4-40 bushing thread). No circuit or panel modifications are required.

Q: What is the primary difference between the C&K 7201P3HCPE and the Grayhill 34ADP16T2M2RT?

A: Both parts meet the same electrical and mechanical specifications. The key difference is electrical life: the C&K part is rated for 100,000 cycles while the Grayhill part is rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the C&K 7201P3HCPE is preferred.

Q: Are there compliance differences between the substitute parts?

A: Yes. The obsolete 7201P3HCKE is RoHS non-compliant. Both substitute parts (7201P3HCPE and 34ADP16T2M2RT) are RoHS compliant. The 7201P3HCPE is also REACH affected, while the 34ADP16T2M2RT is REACH unaffected. For systems requiring regulatory compliance, either substitute part is acceptable.

Q: Will the Grayhill 34ADP16T2M2RT fit the same panel cutout as the C&K parts?

A: Yes. All three parts share identical panel cutout dimensions (circular 6.35mm diameter) and bushing thread specifications (1/4-40), ensuring mechanical interchangeability in panel-mounted applications.

Q: What actuator type differences exist between the substitute parts?

A: The 7201P3HCKE and 7201P3HCPE feature flat anti-rotation actuators, while the Grayhill 34ADP16T2M2RT features a flatted actuator. Both maintain the same 11.43mm length and provide equivalent mechanical interface compatibility.
