C&K 7403SCWZGE Toggle Switch 4PDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7403SCWZGE 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 On-Off-On applications with solder lug termination and IP67 ingress protection. The product is currently active in production with 992 units in stock. Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or design flexibility within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403SCWZGE are qualified based on the following critical parameters that must match or exceed the main part specifications:

• Circuit configuration: 4PDT
• Switch function: On-Off-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC and 28V DC minimum
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 Cycles minimum

The E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all critical electrical and mechanical parameters required for direct substitution. Both parts maintain identical circuit configuration, current and voltage ratings, mounting specifications, and termination style. Minor variations in actuator length (10.41mm vs. 10.67mm) fall within acceptable mechanical tolerances for panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are qualified equivalents for the C&K 7403SCWZGE based on matching electrical specifications, mechanical compatibility, and regulatory compliance. All three parts are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS coding.

The 1004P3T1B1M1QEH variant offers the highest inventory availability at 1991 units, making it the preferred choice for high-volume applications or extended supply chain requirements. The 1004P3T1B1M1QE provides an alternative with 764 units in stock.

The minor actuator length difference (0.26mm) between the C&K part and E-Switch equivalents does not impact panel-mount installation, as both dimensions fall within standard mechanical tolerances for this switch category. All three parts maintain identical panel cutout dimensions (6.35mm circular) and bushing thread specifications (1/4-40), ensuring direct mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH be used interchangeably with the C&K 7403SCWZGE?

A: Yes. Both E-Switch parts meet all critical electrical and mechanical specifications required for direct substitution. They maintain identical 4PDT circuit configuration, 5A current rating at 120V AC and 28V DC, panel-mount design, solder lug termination, and operating temperature range.

Q: What is the significance of the actuator length difference?

A: The actuator length variation (10.67mm for C&K versus 10.41mm for E-Switch) represents a 0.26mm difference. This falls within acceptable mechanical tolerances for panel-mount toggle switches and does not affect installation or functionality when panel cutout dimensions and bushing threads remain identical.

Q: Are all three parts RoHS and REACH compliant?

A: The C&K 7403SCWZGE is ROHS3 compliant and REACH affected. Both E-Switch parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are ROHS3 compliant but REACH unaffected. Verify REACH compliance requirements for your specific application before selection.

Q: Which substitute part should be selected for maximum inventory availability?

A: The E-Switch 1004P3T1B1M1QEH provides the highest inventory level at 1991 units, compared to 764 units for the 1004P3T1B1M1QE and 992 units for the original C&K part.

Q: Do the substitute parts have the same ingress protection rating?

A: The C&K 7403SCWZGE specifies IP67 ingress protection. The E-Switch substitute parts do not list ingress protection specifications in the provided data. Confirm IP67 requirements for your application before substitution.

Q: Are all parts suitable for the same voltage and current applications?

A: Yes. All three parts are rated for 5A at 120V AC and 28V DC, with identical operating temperature ranges of -30°C to 85°C and electrical life of 40,000 cycles.
