C&K 7201P1CWV71ME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P1CWV71ME is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This switch features a flat anti-rotation actuator, PC pin termination, and IP67 ingress protection suitable for sealed applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7201P1CWV71ME is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is functional compatibility, defined by matching circuit configuration (DPDT), switch function (On-On), current and voltage ratings (5A at 120V AC / 28V DC), mounting type (panel mount), actuator specifications (flat anti-rotation, 21.33mm length), termination style (PC pin), panel cutout geometry (6.35mm circular), bushing thread (1/4-40), ingress protection rating (IP67), operating temperature range (-30°C to 85°C), and electrical life (100,000 cycles).

The C&K 7201P1CWV71SE qualifies as a direct substitute based on complete alignment with these parameters. The distinction between the main part and substitute lies in product status and regulatory compliance: the 7201P1CWV71ME is obsolete and RoHS non-compliant, while the 7201P1CWV71SE is active and RoHS compliant.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201P1CWV71SE is the direct substitute for the obsolete 7201P1CWV71ME. Both parts share identical electrical ratings, mechanical dimensions, and functional specifications. The 7201P1CWV71SE is the preferred selection for new designs and replacement applications due to its active product status and RoHS compliance. The transition from the non-compliant 7201P1CWV71ME to the compliant 7201P1CWV71SE aligns with current regulatory requirements while maintaining complete functional equivalence. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 7201P1CWV71SE directly replace the 7201P1CWV71ME without design changes?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, mounting geometry, actuator specifications, and termination style. Direct substitution is possible without circuit or mechanical modifications.

Q: What is the primary difference between these two parts?

A: The 7201P1CWV71ME is obsolete and RoHS non-compliant, while the 7201P1CWV71SE is active and RoHS compliant. All functional and electrical specifications remain identical.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a circular 6.35mm diameter cutout with a 1/4-40 bushing thread, ensuring mechanical interchangeability in existing panel installations.

Q: Do both parts meet the same ingress protection requirements?

A: Yes. Both parts are rated IP67 (dust tight and waterproof) with epoxy sealed terminals, suitable for sealed and harsh environment applications.

Q: What is the electrical life expectancy for both parts?

A: Both parts are rated for 100,000 electrical cycles under specified operating conditions.

Q: Are there any compliance differences that affect system design?

A: The 7201P1CWV71SE is RoHS compliant and REACH affected, while the 7201P1CWV71ME is RoHS non-compliant and REACH unaffected. For applications subject to RoHS or REACH regulations, the 7201P1CWV71SE is the required selection.
