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

Part Overview

The C&K 7401SYZGI is an active production toggle switch featuring 4PDT (four-pole double-throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch is designed for applications requiring simultaneous control of four independent circuits with a single actuator. The part is manufactured with epoxy potting for environmental protection and operates across an industrial temperature range of -30°C to 85°C. Substitute parts are identified when equivalent electrical ratings, mechanical interfaces, and functional specifications align with the original component, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401SYZGI is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Circuit configuration (4PDT), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), and switch function (On-On) must be identical.

Mechanical Compatibility: Panel mount configuration, solder lug termination, circular panel cutout (6.35mm diameter), and 1/4-40 bushing thread must match exactly to ensure physical interchangeability without panel modification.

Environmental Specifications: Operating temperature range (-30°C to 85°C) and moisture sensitivity level (MSL 1 - Unlimited) establish baseline reliability requirements.

Regulatory Compliance: RoHS3 compliance and ECCN classification (EAR99) are mandatory for equivalent substitution in regulated applications.

The E-Switch 1004P1T1B1M1QEH meets all electrical, mechanical, and environmental criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7401SYZGI and E-Switch 1004P1T1B1M1QEH are active production components with ROHS3 compliance and EAR99 classification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts should be based on supply chain availability and lead time considerations. The C&K part carries 835 units in current inventory, while the E-Switch alternative has 1833 units available. Both components are suitable for applications requiring 4PDT switching at 5A/120V AC or 5A/28V DC with panel-mount installation. The identical mechanical interface (6.35mm panel cutout, 1/4-40 bushing thread) and electrical specifications ensure functional equivalence without design modification.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P1T1B1M1QEH directly replace the C&K 7401SYZGI without panel modification?

A: Yes. Both parts feature identical panel cutout dimensions (6.35mm circular) and bushing thread specifications (1/4-40), enabling direct mechanical substitution without panel rework.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both switches are rated for 5A at 120V AC and 28V DC with 4PDT configuration and On-On switching function. Voltage and current specifications are equivalent.

Q: What is the difference in electrical life between these parts?

A: The C&K 7401SYZGI is rated for 100,000 electrical cycles, while the E-Switch 1004P1T1B1M1QEH is rated for 40,000 cycles. This difference does not affect substitution eligibility but should be considered for applications with high switching frequency requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are ROHS3 compliant and classified as EAR99 for export control purposes. The C&K part is REACH Affected, while the E-Switch part is REACH Unaffected; verify REACH compliance requirements for your specific application.

Q: What is the difference in actuator length between these parts?

A: The C&K 7401SYZGI has an actuator length of 10.67mm, while the E-Switch 1004P1T1B1M1QEH has 10.41mm. This 0.26mm difference is within typical manufacturing tolerances and does not affect functional compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in bulk packaging as new original stock.
