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

Part Overview

The C&K 7401SYZQES is a panel-mount toggle switch with 4PDT (four-pole double-throw) configuration, rated for 5A at 120V AC and 28V DC. This switch is designed for applications requiring simultaneous control of four independent circuits with On-On switching function. The product is currently active and in stock, with satin chrome actuator finish and solder lug termination. Alternative equivalent parts may be required due to inventory constraints, application-specific requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7401SYZQES is determined by strict equivalence across 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 (AC/DC) to meet load requirements
• Voltage Ratings: Must support minimum 120V AC and 28V DC to ensure safe operation across specified voltage ranges
• Mounting Type: Must be Panel Mount with identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread (1/4-40) for mechanical compatibility
• Termination Style: Must be Solder Lug for PCB integration compatibility
• Operating Temperature: Must support -30°C ~ 85°C range
• Regulatory Compliance: Must maintain ROHS3 compliance for environmental standards

The E-Switch 1004P1T1B1M1QEH meets all critical substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7401SYZQES and E-Switch 1004P1T1B1M1QEH are active products with ROHS3 compliance, meeting current environmental and regulatory requirements. Selection between these parts should be based on the following factors:

C&K 7401SYZQES is the primary specification part with 100,000 electrical life cycles, suitable for applications requiring extended operational longevity and higher cycle durability.

E-Switch 1004P1T1B1M1QEH is a qualified equivalent with 40,000 electrical life cycles and epoxy sealed terminals. This part is suitable for applications where the lower cycle rating is acceptable and where REACH unaffected status is a procurement advantage.

Both parts share identical electrical ratings, mechanical interfaces, and temperature operating ranges, ensuring direct functional interchangeability in panel-mount 4PDT switching applications rated for 5A at 120V AC or 28V DC.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P1T1B1M1QEH directly replace the C&K 7401SYZQES?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical circuit configuration (4PDT), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and operating temperature range (-30°C ~ 85°C). The primary difference is electrical life rating: C&K provides 100,000 cycles versus E-Switch's 40,000 cycles.

Q: What are the mechanical compatibility requirements?

A: Both parts are panel-mount switches with identical panel cutout specifications (circular 6.35mm diameter) and bushing thread (1/4-40). Actuator length differs slightly (C&K 10.67mm versus E-Switch 10.41mm), but this variation does not affect panel mounting or operational compatibility.

Q: Are there regulatory compliance differences?

A: Both parts are ROHS3 compliant. The C&K part is REACH Affected, while the E-Switch part is REACH Unaffected. Selection should align with your supply chain and regulatory requirements.

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

A: The C&K 7401SYZQES is rated for 100,000 electrical 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 durability. For standard-duty applications, the E-Switch part is functionally adequate.

Q: Are the termination styles identical?

A: Yes. Both parts use solder lug termination, ensuring compatibility with standard PCB soldering processes and electrical connection methods.
