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

Part Overview

The C&K 7301TZQES is a 3PDT toggle switch rated for 5A at 120V AC with panel mount configuration and solder lug termination. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a standard round actuator with satin chrome finish and operates across a temperature range of -30°C to 85°C with 100,000 electrical cycles rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7301TZQES is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Circuit configuration: 3PDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Actuator type: Standard Round
• Actuator length: 17.45mm
• Bushing thread: 15/32-32

Electrical Compatibility Criteria:

• Current rating: Minimum 5A AC/DC
• Voltage rating AC: Minimum 120V
• Voltage rating DC: Minimum 28V

Mechanical Compatibility Criteria:

• Panel cutout dimensions: Circular 11.91mm Dia (where specified)
• Operating temperature range: Must encompass -30°C to 85°C minimum

Parts meeting all primary equivalence criteria and electrical compatibility thresholds are classified as direct substitutes. Parts exceeding the specified electrical ratings remain compatible for applications requiring the 7301TZQES performance envelope.

Parameter Comparison

Engineering Selection Recommendations

7301TZQE (C&K): This part is the primary substitute for the obsolete 7301TZQES. It maintains identical electrical ratings (5A at 120V AC, 28V DC), mechanical dimensions, and operating temperature range. Both parts are ROHS3 compliant with equivalent electrical life ratings of 100,000 cycles. The 7301TZQE is currently in active production status, ensuring supply chain availability. The only documented difference is the terminal sealing method (epoxy sealed versus satin chrome actuator finish), which does not affect electrical or mechanical compatibility.

A323T1TZQ (Electroswitch): This part provides enhanced electrical performance with 6A current rating at 125V AC, exceeding the 7301TZQES specifications. It maintains identical mechanical compatibility including panel cutout dimensions, bushing thread, and actuator geometry. The operating temperature range extends to 90°C, providing broader thermal coverage. The electrical life rating of 60,000 cycles is lower than the main part. RoHS compliance is confirmed. This substitute is suitable for applications where higher current or voltage margins are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 7301TZQE directly replace the obsolete 7301TZQES?

A: Yes. The 7301TZQE maintains identical electrical ratings (5A at 120V AC, 28V DC), circuit configuration (3PDT On-On), mechanical dimensions (17.45mm actuator, 15/32-32 bushing thread), and operating temperature range (-30°C to 85°C). Both parts are ROHS3 compliant with 100,000 cycle electrical life. Panel mount configuration and solder lug termination are identical.

Q: What are the key differences between the 7301TZQE and A323T1TZQ?

A: The A323T1TZQ offers higher electrical ratings (6A at 125V AC versus 5A at 120V AC) and extended operating temperature to 90°C. However, it has a lower electrical life rating of 60,000 cycles compared to 100,000 cycles for both C&K parts. Mechanical compatibility is maintained across all three parts for panel mount applications with 15/32-32 bushing thread.

Q: Are there any compliance differences between these substitutes?

A: The 7301TZQES and 7301TZQE are both ROHS3 compliant. The A323T1TZQ is RoHS compliant. All three parts carry EAR99 ECCN classification and share the same HTSUS code (8536.50.9065). REACH status differs: the C&K parts are REACH Affected, while the Electroswitch part shows Vendor Undefined status.

Q: Can the A323T1TZQ be used in applications designed for the 7301TZQES?

A: Yes, with consideration of electrical life requirements. The A323T1TZQ exceeds the electrical and thermal specifications of the 7301TZQES, making it mechanically and electrically compatible for panel mount 3PDT On-On switching applications. The reduced electrical life rating (60,000 versus 100,000 cycles) should be evaluated against application duty cycle requirements.

Q: What is the panel cutout dimension compatibility?

A: The 7301TZQES and 7301TZQE both specify circular panel cutout dimensions of 11.91mm diameter. The A323T1TZQ does not provide panel cutout dimension specifications in the available data. All three parts use identical 15/32-32 bushing thread, ensuring mechanical fit compatibility in standard panel mount installations.
