Equivalent & Substitute Parts for C&K 7301SYZQES Toggle Switch 3PDT

Part Overview

The C&K 7301SYZQES is a panel-mount toggle switch with 3PDT (three-pole, double-throw) configuration, rated for 5A at 120V AC and 28V DC. This switch is designed for On-On applications with satin chrome actuator finish and solder lug termination. The part is Active status and ROHS3 compliant, making it suitable for modern industrial and commercial control applications.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for alternative manufacturers meeting identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7301SYZQES is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Must be 3PDT
• Switch Function: Must be On-On
• Current Rating: Must support minimum 5A (AC/DC)
• Voltage Rating - AC: Must support minimum 120V
• Voltage Rating - DC: Must support minimum 28V
• Mounting Type: Must be Panel Mount
• Panel Cutout Dimensions: Must be Circular - 6.35mm Dia
• Bushing Thread: Must be 1/4-40
• Termination Style: Must be Solder Lug
• Operating Temperature Range: Must encompass -30°C to 85°C

Based on these criteria, the following E-Switch parts qualify as direct substitutes:

Full Electrical and Mechanical Equivalents:

• 1003P1T1B1M1QEH (E-Switch Series 100)
• 1003P1T2B1M1QE (E-Switch Series 100)

Partial Substitute (Reduced Electrical Rating):

• 1003P1T1B1M1RE (E-Switch Series 100) — Lower current and voltage ratings; suitable only for applications not requiring full 5A/120V capability

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Full Electrical Equivalence):

E-Switch 1003P1T1B1M1QEH and 1003P1T2B1M1QE are electrically and mechanically equivalent to the C&K 7301SYZQES. Both parts maintain 5A/120V AC and 28V DC ratings with identical circuit configuration, mounting geometry, and termination. Both are ROHS3 compliant. The primary difference between these two E-Switch options is actuator length: 1003P1T1B1M1QEH provides 10.41mm length (closest to original 10.67mm), while 1003P1T2B1M1QE provides 5.08mm length for applications requiring shorter panel protrusion.

Note: E-Switch parts have reduced electrical life (40,000 cycles versus 100,000 cycles for the C&K original). REACH compliance status differs; the C&K part is REACH Affected while E-Switch substitutes are REACH Unaffected.

For Reduced-Load Applications Only:

E-Switch 1003P1T1B1M1RE is suitable only for applications where current demand does not exceed 0.4VA and voltage does not exceed 20V AC/DC. This part shares identical mechanical specifications but reduced electrical ratings and is not a general substitute for the 7301SYZQES.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 1003P1T1B1M1QEH directly replace the C&K 7301SYZQES in all applications?

A: Yes, for applications requiring 5A at 120V AC or 28V DC with 3PDT On-On switching. The electrical ratings, circuit configuration, mounting dimensions, and operating temperature range are identical. Verify that the 10.41mm actuator length is compatible with your panel thickness and control interface requirements.

Q: What is the significance of the different actuator lengths between 1003P1T1B1M1QEH (10.41mm) and 1003P1T2B1M1QE (5.08mm)?

A: Actuator length determines how far the toggle switch extends beyond the panel surface. The 1003P1T1B1M1QEH (10.41mm) is closer to the original 7301SYZQES (10.67mm) and is preferred for standard panel-mount applications. The 1003P1T2B1M1QE (5.08mm) is suitable for applications with space constraints or where shorter actuation travel is required.

Q: Why does the E-Switch substitute have lower electrical life (40,000 cycles) compared to the C&K original (100,000 cycles)?

A: Electrical life rating reflects the tested cycle count at rated electrical load. The reduced rating for E-Switch parts indicates different internal contact materials or design. For applications requiring extended cycle life beyond 40,000 operations, the C&K 7301SYZQES is the appropriate choice.

Q: Is E-Switch 1003P1T1B1M1RE a suitable substitute?

A: No, not as a general substitute. The 1003P1T1B1M1RE has reduced electrical ratings (0.4VA at 20V maximum) and is suitable only for low-power signal switching applications. It cannot handle the 5A/120V requirements of the original 7301SYZQES.

Q: What is the difference in REACH compliance between the C&K and E-Switch parts?

A: The C&K 7301SYZQES is REACH Affected, indicating it may contain substances of concern under REACH regulations. E-Switch substitutes are REACH Unaffected. For applications subject to REACH compliance requirements, the E-Switch alternatives provide regulatory advantage.

Q: Are all substitute parts available in the same packaging?

A: Yes. The C&K 7301SYZQES and all E-Switch substitutes are supplied in Bulk packaging, suitable for direct integration into manufacturing and assembly processes.
