C&K 7301SCWZQE Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7301SCWZQE is a panel-mount toggle switch with 3PDT (three-pole, double-throw) configuration, rated for 5A at 120V AC and 28V DC. This switch is designed for applications requiring reliable on-on switching with IP67 ingress protection and epoxy-sealed terminals. The part is currently active in production with 903 units in stock. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical compatibility, and functional specifications to ensure direct replacement capability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on electrical and mechanical parameter compatibility with the main part. The primary substitution criteria are:

• Circuit Configuration: 3PDT (three-pole, double-throw)
• Switch Function: On-On operation
• Electrical Ratings: Current and voltage specifications must match or exceed the main part requirements
• Mechanical Compatibility: Panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and solder lug termination
• Environmental Specifications: Operating temperature range and RoHS compliance

E-Switch parts 1003P1T1B1M1QEH and 1003P1T2B1M1QE meet all primary electrical and mechanical compatibility criteria with the C&K 7301SCWZQE. The E-Switch 1003P1T1B1M1RE has reduced electrical ratings (0.4VA at 20V) and is suitable only for lower-power applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Full Electrical and Mechanical Compatibility):

E-Switch 1003P1T1B1M1QEH and E-Switch 1003P1T2B1M1QE are suitable direct substitutes for the C&K 7301SCWZQE in applications requiring 5A at 120V AC or 28V DC with 3PDT on-on switching. Both parts maintain identical electrical ratings, mechanical mounting dimensions, and RoHS3 compliance. The primary difference is actuator length: 1003P1T1B1M1QEH has 10.41mm length (comparable to the main part's 10.67mm), while 1003P1T2B1M1QE has a shorter 5.08mm actuator. Selection between these two depends on panel depth and actuator accessibility requirements. Both E-Switch parts have reduced electrical life (40,000 cycles versus 100,000 cycles for the C&K part).

Limited Substitution (Reduced Electrical Ratings):

E-Switch 1003P1T1B1M1RE is not suitable as a direct substitute due to significantly reduced electrical ratings (0.4VA at 20V maximum). This part is applicable only in low-power signal switching applications and cannot replace the main part in standard 5A/120V applications.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 1003P1T1B1M1QEH directly replace the C&K 7301SCWZQE?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC/28V DC), 3PDT on-on configuration, panel mount compatibility (6.35mm circular cutout, 1/4-40 bushing thread), and solder lug termination. The 0.26mm difference in actuator length (10.41mm versus 10.67mm) is within typical mechanical tolerance for panel-mount switches.

Q: What is the difference between E-Switch 1003P1T1B1M1QEH and 1003P1T2B1M1QE?

A: Both parts have identical electrical specifications and mechanical mounting compatibility. The primary difference is actuator length: 1003P1T1B1M1QEH has 10.41mm length, while 1003P1T2B1M1QE has 5.08mm length. Selection depends on panel depth and operator accessibility. The shorter actuator (1003P1T2B1M1QE) is suitable for shallow panel installations.

Q: Why is E-Switch 1003P1T1B1M1RE not recommended as a substitute?

A: The 1003P1T1B1M1RE has reduced electrical ratings (0.4VA at 20V maximum) compared to the main part's 5A at 120V AC specification. This part is designed for low-power signal switching applications and cannot safely handle the electrical loads of standard 5A/120V circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The C&K 7301SCWZQE and all E-Switch substitute parts (1003P1T1B1M1QEH, 1003P1T2B1M1QE, and 1003P1T1B1M1RE) are ROHS3 compliant.

Q: What is the electrical life difference between the main part and substitutes?

A: The C&K 7301SCWZQE has 100,000 electrical life cycles, while E-Switch parts have 40,000 cycles. For applications requiring extended operational life, the C&K part is preferred. For standard industrial applications, the reduced cycle rating of E-Switch parts is typically acceptable.

Q: Do the substitute parts have IP67 ingress protection?

A: The C&K 7301SCWZQE specifies IP67 (dust tight, waterproof) protection. The E-Switch substitute parts do not list ingress protection specifications in the provided data. For applications requiring sealed operation, verify IP67 capability with the E-Switch manufacturer before substitution.
