Toggle Switch 7401SH3CGE Equivalent & Substitute Parts

Part Overview

The C&K 7401SH3CGE is a 4PDT panel mount toggle switch rated for 5A at 120V AC and 28V DC. This switch features epoxy sealed terminals, a circular 6.35mm panel cutout, and operates across -30°C to 85°C. The product is active and ROHS3 compliant with an electrical life of 100,000 cycles. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit configuration requirements necessitate alternative sourcing due to inventory constraints or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The MTA406NPC from TE Connectivity ALCOSWITCH Switches qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: 4PDT
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout: Circular - 6.35mm diameter (compatible with 1/4-40 bushing thread)
• Termination style: PC Pin
• Voltage rating - DC: 28V
• Epoxy sealed terminals
• RoHS3 compliance
• REACH affected status

Allowable Variations:

• Current rating: MTA406NPC rated 6A AC (exceeds 5A requirement) and 4A DC
• Voltage rating - AC: MTA406NPC rated 125V (exceeds 120V requirement)
• Operating temperature: MTA406NPC rated -20°C to 80°C (narrower range than 7401SH3CGE)
• Actuator length: MTA406NPC 10.49mm versus 7401SH3CGE 10.16mm (minor mechanical difference)

Parameter Comparison

Engineering Selection Recommendations

The MTA406NPC is electrically and mechanically compatible with the 7401SH3CGE for applications requiring 4PDT panel mount toggle switches with PC pin termination. Both parts maintain ROHS3 and REACH compliance. The MTA406NPC provides higher current capacity (6A AC versus 5A AC) and equivalent DC voltage rating (28V). The operating temperature range of the MTA406NPC (-20°C to 80°C) is narrower than the 7401SH3CGE (-30°C to 85°C); applications requiring operation below -20°C or above 80°C must use the 7401SH3CGE. The 0.33mm difference in actuator length (10.49mm versus 10.16mm) is within typical mechanical tolerances for panel mount installations with 1/4-40 bushing threads and 6.35mm circular cutouts.

Frequently Asked Questions (FAQ)

Q: Can the MTA406NPC replace the 7401SH3CGE in all applications?

A: The MTA406NPC is suitable for most applications. However, if your circuit operates below -20°C or above 80°C, the 7401SH3CGE must be used due to its extended operating temperature range.

Q: Are the panel cutout dimensions identical?

A: Yes. Both switches use a 6.35mm circular panel cutout with 1/4-40 bushing thread, ensuring mechanical interchangeability in standard panel mount installations.

Q: What is the difference in current ratings?

A: The 7401SH3CGE is rated 5A AC. The MTA406NPC is rated 6A AC and 4A DC. For applications requiring DC operation, verify that 4A DC meets your circuit requirements.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the 7401SH3CGE and MTA406NPC are ROHS3 compliant and REACH affected, meeting current environmental standards.

Q: Does the 0.33mm actuator length difference affect installation?

A: No. The actuator length difference (10.16mm versus 10.49mm) is negligible for panel mount applications and does not affect mechanical fit or electrical performance.

Q: What is the electrical life of the MTA406NPC?

A: The electrical life specification for the MTA406NPC is not provided in the available data. The 7401SH3CGE specifies 100,000 cycles.
