C&K 7401SYZGE Toggle Switch 4PDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7401SYZGE is an active-status toggle switch featuring 4PDT (four-pole double-throw) configuration with 5A current rating at 120V AC and 28V DC. This panel-mount switch is designed for applications requiring simultaneous control of four independent circuits with On-On switching function. The part is manufactured with epoxy sealed terminals and operates across -30°C to 85°C temperature range. Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, manage inventory optimization, and maintain design compatibility across production batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7401SYZGE is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Must be 4PDT to maintain four independent circuit control capability
• Switch Function: Must be On-On to preserve switching behavior
• Current Rating: Must support minimum 5A at both AC and DC
• Voltage Ratings: Must support minimum 120V AC and 28V DC
• Mounting Type: Must be Panel Mount with identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread (1/4-40)
• Termination Style: Must be Solder Lug for PCB integration compatibility
• Operating Temperature: Must cover -30°C ~ 85°C range
• RoHS Compliance: Must maintain ROHS3 Compliant status for regulatory alignment

The E-Switch 1004P1T1B1M1QEH meets all mandatory substitution criteria and qualifies as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch 1004P1T1B1M1QEH qualifies as a functional equivalent to the C&K 7401SYZGE based on matching electrical specifications, mechanical dimensions, and regulatory compliance status. Both parts maintain ROHS3 Compliant certification and support identical voltage and current ratings across AC and DC applications.

Selection between these parts should account for the following factors:

• Electrical Life Rating: The C&K 7401SYZGE specifies 100,000 cycles versus 40,000 cycles for the E-Switch equivalent. Applications requiring extended cycle life should prioritize the C&K part.
• REACH Regulatory Scope: The C&K part carries REACH Affected status while the E-Switch part is REACH Unaffected. Supply chain and regulatory requirements may influence part selection based on end-market destination.
• Actuator Length Variance: The 0.26mm difference in actuator length (10.67mm vs 10.41mm) is within typical mechanical tolerance and does not affect panel mount compatibility or functional operation.
• Product Status: Both parts maintain Active status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P1T1B1M1QEH be used as a direct replacement for the C&K 7401SYZGE in existing designs?

A: Yes. Both parts share identical circuit configuration (4PDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), panel mount dimensions, and termination style. The mechanical and electrical interfaces are compatible.

Q: What is the significance of the electrical life rating difference?

A: The C&K 7401SYZGE is rated for 100,000 cycles while the E-Switch 1004P1T1B1M1QEH is rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the C&K part provides greater cycle endurance. For standard-duty applications, both parts meet functional requirements.

Q: Are there any panel cutout or mounting differences between these parts?

A: No. Both parts feature identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread specification (1/4-40). Panel integration is mechanically interchangeable.

Q: Does the actuator length difference affect compatibility?

A: The 0.26mm variance in actuator length (C&K 10.67mm vs E-Switch 10.41mm) falls within standard mechanical tolerance and does not impact panel mount compatibility or switch operation.

Q: What regulatory compliance differences exist between these parts?

A: Both parts are ROHS3 Compliant. The C&K 7401SYZGE carries REACH Affected status while the E-Switch 1004P1T1B1M1QEH is REACH Unaffected. Regulatory requirements for your end market may influence part selection.
