EN2C3M20G2 Equivalent & Substitute Parts

Part Overview

The EN2C3M20G2 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 they maintain functional equivalence across critical electrical and mechanical parameters while meeting the same compliance and certification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EN2C3M20G2 are identified based on the following critical parameters that determine functional compatibility:

• Connector type and gender (Plug, Male Pins)
• Number of positions (3-position configuration)
• Contact finish material (Gold plating for mating surfaces)
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Ingress protection capability (minimum IP65 or higher)

The substitute part 21031111305 (HARTING Harax® M12-S series) meets these core functional criteria. However, differences exist in termination method, fastening mechanism, and electrical ratings that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the EN2C3M20G2 and 21031111305 maintain Active product status and satisfy ROHS3 compliance and REACH unaffected classifications. Selection between these parts depends on application-specific requirements:

The EN2C3M20G2 is suitable for applications requiring bayonet lock fastening, crimp or solder cup termination flexibility, and IP66/IP67/IP68 ingress protection at 125VAC/DC voltage levels.

The 21031111305 provides higher current capacity (4A versus 2A) and threaded fastening with IDC termination, but operates at reduced voltage (32V) and lower ingress protection (IP65/IP67 versus IP66/IP67/IP68). This substitute is appropriate for applications where higher current handling and threaded coupling are prioritized over voltage rating and maximum ingress protection.

Both parts support identical operating temperature ranges (-40°C ~ 85°C) and maintain equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 21031111305 directly replace the EN2C3M20G2 in all applications?

A: Direct replacement is not universal. The 21031111305 differs in termination method (IDC versus crimp/solder cup), fastening type (threaded versus bayonet), voltage rating (32V versus 125VAC/DC), and ingress protection level (IP65/IP67 versus IP66/IP67/IP68). Application requirements must be evaluated against these parameters.

Q: What is the primary difference in termination between these parts?

A: The EN2C3M20G2 uses crimp or solder cup termination, allowing flexible wire attachment methods. The 21031111305 uses IDC (Insulation Displacement Contact) termination, which requires specific IDC-compatible cable assemblies.

Q: Are both parts suitable for marine applications?

A: Both parts list marine applications in their specifications. However, the EN2C3M20G2 provides higher ingress protection (IP66/IP67/IP68) compared to the 21031111305 (IP65/IP67), which may be relevant for specific marine environmental conditions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the impact of voltage rating differences?

A: The EN2C3M20G2 is rated for 125VAC/DC, while the 21031111305 is rated for 32V. Applications requiring AC voltage or voltages exceeding 32V must use the EN2C3M20G2.

Q: How do the fastening mechanisms differ?

A: The EN2C3M20G2 uses bayonet lock fastening for quick-connect/disconnect applications. The 21031111305 uses threaded fastening, which provides a more secure, permanent connection but requires rotational coupling.
