EN2C3M20G3 Equivalent & Substitute Parts

Part Overview

The EN2C3M20G3 is a 3-position circular connector plug with male pins, manufactured by Switchcraft Inc. under the EN2™ series. This connector features gold-plated mating contacts, crimp or solder cup termination, and bayonet lock fastening. The part is classified as Active product status and is designed for applications requiring IP66/IP67/IP68 ingress protection in communication systems, industrial, marine, and medical environments.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's functional requirements, enabling component interchangeability in system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EN2C3M20G3 is determined by the following critical parameters:

• Connector Configuration: Plug with male pins, 3-position
• Contact Material & Finish: Gold-plated mating surface for corrosion resistance
• Electrical Performance: Current and voltage ratings must support the intended application
• Environmental Protection: Ingress protection rating for sealed applications
• Operating Temperature: Functional range of -40°C to 85°C
• Regulatory Compliance: ROHS3 and REACH compliance status

The substitute part 21031111305 (HARTING Harax® M12-S series) shares the core functional attributes of a 3-position male plug connector with gold-plated contacts and equivalent operating temperature range. However, differences in termination method, fastening mechanism, and electrical ratings must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the EN2C3M20G3 and 21031111305 maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The EN2C3M20G3 provides higher voltage rating (125VAC/DC) and superior ingress protection (IP66/IP67/IP68), making it suitable for demanding sealed environments. The 21031111305 offers higher current capacity (4A) but operates at lower voltage (32V) with reduced ingress protection (IP65/IP67).

Selection between these parts depends on application-specific electrical requirements and environmental conditions. The bayonet lock fastening of the EN2C3M20G3 differs from the threaded fastening of the 21031111305, affecting mechanical integration. Termination method compatibility—crimp/solder cup versus IDC—must align with existing cable assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 21031111305 directly replace the EN2C3M20G3 in all applications?

A: Direct replacement is not universal. While both are 3-position male plug connectors with gold-plated contacts and equivalent operating temperature ranges, the 21031111305 has lower voltage rating (32V vs. 125VAC/DC) and reduced ingress protection (IP65/IP67 vs. IP66/IP67/IP68). Application voltage and environmental sealing requirements must be verified before substitution.

Q: What are the primary differences in termination methods?

A: The EN2C3M20G3 uses crimp or solder cup termination, requiring mechanical crimping tools or soldering equipment. The 21031111305 uses IDC (Insulation Displacement Contact) termination, which requires IDC-compatible tooling. Cable assembly processes and available equipment determine which termination method is practical for integration.

Q: Are both parts suitable for marine applications?

A: The EN2C3M20G3 is explicitly listed for marine applications with IP66/IP67/IP68 protection. The 21031111305 provides IP65/IP67 protection, which is lower. Marine environment selection should prioritize the EN2C3M20G3 unless application-specific conditions permit reduced ingress protection.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory compliance for industrial and commercial markets. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.

Q: What is the significance of the fastening type difference?

A: The EN2C3M20G3 uses bayonet lock fastening, while the 21031111305 uses threaded fastening. These are mechanically incompatible connection methods. System design and mating connector specifications determine which fastening type is required.
