C&K 7401SCWCGE Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7401SCWCGE is an active production toggle switch featuring 4PDT (four-pole double-throw) circuitry with panel mount configuration. This switch is rated for 5A at 120V AC and 28V DC, designed for applications requiring sealed, waterproof operation in industrial and aerospace environments. The part is ROHS3 compliant and maintains IP67 ingress protection with epoxy sealed terminals. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for this active product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401SCWCGE is determined by the following critical parameters:

• Circuit Configuration: Must be 4PDT to maintain identical switching topology
• Switch Function: Must be On-On for equivalent operational behavior
• Mounting Type: Must be Panel Mount with compatible bushing thread (1/4-40)
• Termination Style: Must be PC Pin for direct PCB compatibility
• Voltage Ratings: AC rating must meet or exceed 120V; DC rating must meet or exceed 28V
• Current Rating: Must support minimum 5A at rated voltage
• Ingress Protection: IP67 or equivalent sealing required for environmental protection
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Operating Temperature: Must encompass or overlap the -30°C to 85°C range

The TE Connectivity ALCOSWITCH MTA406NPC meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7401SCWCGE and TE Connectivity MTA406NPC are active production components with ROHS3 compliance and REACH affected status, supporting long-term supply chain viability.

The C&K 7401SCWCGE is the primary specification with documented IP67 ingress protection and extended operating temperature range (-30°C to 85°C), making it suitable for harsh environmental applications requiring maximum temperature margin.

The TE Connectivity MTA406NPC serves as a functional substitute for applications where DC current requirements do not exceed 4A and operating temperatures remain above -20°C. The MTA406NPC provides equivalent AC current capacity (6A) and maintains compatible electrical and mechanical interfaces. Selection between these parts should be based on specific application requirements for DC current, low-temperature operation, and environmental sealing specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity MTA406NPC directly replace the C&K 7401SCWCGE in all applications?

A: Direct replacement is possible for applications operating at AC voltage with DC current requirements not exceeding 4A and minimum operating temperatures above -20°C. Applications requiring the full 5A DC rating or operation below -20°C should retain the C&K 7401SCWCGE.

Q: Are the panel cutout dimensions identical between these parts?

A: Both parts feature 1/4-40 bushing thread and panel mount configuration. Verify circular panel cutout diameter (6.35mm for the 7401SCWCGE) with the MTA406NPC technical documentation before installation.

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

A: The C&K 7401SCWCGE has an actuator length of 10.67mm, while the TE Connectivity MTA406NPC has 10.49mm. This 0.18mm difference is negligible for most panel mount applications but should be confirmed for space-constrained designs.

Q: Do both parts meet the same environmental sealing requirements?

A: The C&K 7401SCWCGE is specified as IP67 (dust tight, waterproof). The TE Connectivity MTA406NPC ingress protection rating is not provided in the specification. Confirm IP67 or equivalent sealing capability with the manufacturer before substitution in sealed or wet environments.

Q: Are both parts RoHS compliant?

A: Yes, both the C&K 7401SCWCGE and TE Connectivity MTA406NPC are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic component procurement.
