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

Part Overview

The C&K 7301SCWZBE is a panel-mount toggle switch with 3PDT (three-pole, double-throw) configuration, rated for 0.4VA at 20V AC/DC. This switch is designed for low-power control applications requiring sealed, waterproof operation. The part is currently active in production with ROHS3 compliance and IP67 ingress protection. Equivalent and substitute parts are identified based on matching circuit topology, mounting configuration, and electrical ratings within acceptable operational parameters.

Substitute Part Grouping Explanation

Substitute parts for the 7301SCWZBE are identified based on the following substitution criteria:

Primary Substitution Criteria (Mandatory Match):

• Circuit configuration: 3PDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C
• RoHS compliance: ROHS3 Compliant

Secondary Substitution Criteria (Electrical Ratings): Substitute parts must operate within or exceed the electrical specifications of the main part. The 7301SCWZBE operates at 0.4VA, 20V AC/DC. Substitutes rated for higher current or voltage ratings are acceptable for this application.

Identified Substitute Parts:

1. E-Switch 1003P1T1B1M1RE - Direct electrical equivalent with matching 0.4VA, 20V ratings
2. E-Switch 1003P1T1B1M1QEH - Higher-rated substitute (5A, 120V AC / 28V DC)
3. E-Switch 1003P1T2B1M1QE - Higher-rated substitute (5A, 120V AC / 28V DC) with shorter actuator

Parameter Comparison

Engineering Selection Recommendations

E-Switch 1003P1T1B1M1RE - Primary Substitute

This part provides direct electrical equivalence to the 7301SCWZBE with identical current (0.4VA) and voltage ratings (20V AC/DC). Both parts maintain ROHS3 compliance and active product status. The primary consideration is the reduced electrical life specification (40,000 cycles versus 100,000 cycles). This substitute is suitable for applications where the lower cycle rating does not conflict with operational requirements.

E-Switch 1003P1T1B1M1QEH and 1003P1T2B1M1QE - Higher-Rated Substitutes

These parts exceed the electrical specifications of the 7301SCWZBE, rated for 5A at 120V AC / 28V DC. Both maintain ROHS3 compliance and active product status. The key differentiator is actuator length: 1003P1T1B1M1QEH provides 10.41mm length (comparable to the original 10.67mm), while 1003P1T2B1M1QE provides a shorter 5.08mm actuator. Selection between these variants depends on panel depth and actuator accessibility requirements. Both are suitable for applications requiring higher electrical capacity than the original specification.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P1T1B1M1RE directly replace the C&K 7301SCWZBE?

A: Yes. The 1003P1T1B1M1RE provides identical electrical ratings (0.4VA, 20V AC/DC), matching circuit configuration (3PDT), and compatible mechanical specifications (panel mount, solder lug termination, 1/4-40 bushing thread). Both parts are ROHS3 compliant and active. The electrical life specification differs (40,000 versus 100,000 cycles), which should be evaluated against application duty cycle requirements.

Q: What is the difference between the three E-Switch substitute options?

A: All three E-Switch parts share the same 3PDT circuit configuration and panel-mount design. The 1003P1T1B1M1RE matches the original electrical rating (0.4VA, 20V). The 1003P1T1B1M1QEH and 1003P1T2B1M1QE both provide higher electrical capacity (5A, 120V AC / 28V DC). The distinction between the two higher-rated options is actuator length: 1003P1T1B1M1QEH has a 10.41mm actuator, while 1003P1T2B1M1QE has a 5.08mm actuator. Actuator length selection depends on panel depth and operator accessibility.

Q: Are the higher-rated E-Switch parts (5A, 120V) suitable for the original 0.4VA, 20V application?

A: Yes. Higher electrical ratings are acceptable for applications requiring lower power levels. The 1003P1T1B1M1QEH and 1003P1T2B1M1QE can operate safely in circuits designed for 0.4VA, 20V operation. Selection should consider actuator length compatibility with the panel installation.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts listed are ROHS3 compliant and maintain active product status, matching the compliance profile of the original C&K 7301SCWZBE. The original part carries REACH Affected status, while E-Switch substitutes are REACH Unaffected.

Q: How do the ingress protection ratings compare?

A: The C&K 7301SCWZBE specifies IP67 (dust tight, waterproof) with epoxy sealed terminals. The E-Switch substitute parts do not specify an ingress protection rating in the provided data. Applications requiring IP67 protection should confirm ingress protection capability with the E-Switch manufacturer before substitution.

Q: What is the impact of the reduced electrical life specification in the E-Switch substitutes?

A: The C&K 7301SCWZBE is rated for 100,000 electrical cycles, while all E-Switch substitutes are rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, this difference should be evaluated against the specific duty cycle. Lower-cycle-count applications are unaffected by this specification difference.
