EN2C3M20DC Equivalent & Substitute Parts

Part Overview

The EN2C3M20DC is a 3-position circular connector plug with male pins manufactured by Switchcraft Inc. under the EN2™ series. This active product features crimp or solder cup termination, bayonet lock fastening, and gold-plated mating contacts rated for 2A at 125VAC/DC. The connector is designed for free-hanging in-line mounting in communication systems, industrial, marine, and medical applications, with IP66/IP67/IP68 ingress protection and UL94 V-0 flammability compliance.

Equivalent and substitute parts are identified when alternative connectors meet the core functional requirements: 3-position male pin configuration, compatible termination methods, matching ingress protection levels, and equivalent electrical ratings within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EN2C3M20DC is determined by the following critical parameters:

• Connector Configuration: 3-position male pin plug
• Termination Compatibility: Crimp, solder cup, or IDC (insulation displacement contact) termination methods are functionally equivalent for wire attachment
• Electrical Ratings: Current rating must equal or exceed 2A; voltage rating must equal or exceed 125VAC/DC
• Ingress Protection: IP65 or higher rating maintains environmental sealing requirements
• Operating Temperature Range: Must encompass -40°C ~ 85°C
• Contact Finish: Gold plating for corrosion resistance and signal integrity
• Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part 21031111305 (HARTING Harax® M12-S) meets these criteria with the following equivalencies: 3-position male pin configuration, IDC termination (functionally compatible with crimp/solder cup), 4A current rating (exceeds 2A requirement), IP65/IP67 ingress protection (meets environmental sealing), matching -40°C ~ 85°C operating temperature, gold contact finish, and ROHS3/REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

EN2C3M20DC (Primary Selection)

The EN2C3M20DC remains the primary specification when bayonet lock fastening is required and crimp or solder cup termination is the assembly method. This connector is active product status with full ROHS3 compliance and REACH unaffected designation. The 125VAC/DC voltage rating and 2A current capacity are suitable for specified applications. IP66/IP67/IP68 ingress protection provides maximum environmental sealing for marine and outdoor industrial deployments.

21031111305 (Substitute Selection)

The HARTING 21031111305 serves as a functional substitute when IDC termination is acceptable and threaded fastening is compatible with the mechanical interface. This connector exceeds the current rating requirement (4A vs. 2A) and maintains equivalent operating temperature range. The voltage rating of 32V is lower than the primary part; substitution is appropriate only when circuit voltage does not exceed 32V. IP65/IP67 ingress protection is suitable for most industrial and communication applications, though IP68 waterproof rating is not available. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the 21031111305 replace the EN2C3M20DC in all applications?

A: The 21031111305 is functionally equivalent for 3-position male pin connector requirements when the following conditions are met: circuit voltage does not exceed 32V, IDC termination is acceptable in the assembly process, threaded fastening is mechanically compatible with the connector interface, and IP65/IP67 ingress protection meets environmental requirements. If the application requires 125VAC/DC voltage capability or IP68 waterproof rating, the EN2C3M20DC is the required specification.

Q: What is the difference between crimp/solder cup and IDC termination?

A: Crimp and solder cup termination require manual wire preparation and connection to individual contacts. IDC (insulation displacement contact) termination automatically pierces the wire insulation when inserted, eliminating manual stripping. Both methods achieve equivalent electrical connections; selection depends on assembly equipment and process requirements.

Q: Are the fastening types interchangeable?

A: Bayonet lock and threaded fastening are mechanically distinct. Bayonet lock provides quick-connect capability with rotational engagement; threaded fastening requires axial rotation for mating. Substitution is valid only when the mechanical interface of the receiving connector accommodates the fastening type.

Q: What does IP65/IP67 versus IP66/IP67/IP68 mean for environmental protection?

A: IP65 provides dust-tight and low-pressure water jet protection. IP66 adds high-pressure water jet protection. IP67 permits temporary immersion. IP68 permits continuous immersion at specified depth. The EN2C3M20DC supports all three levels; the 21031111305 supports IP65 and IP67. Selection depends on the severity of environmental exposure in the application.

Q: Are both parts RoHS compliant?

A: Yes. Both EN2C3M20DC and 21031111305 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.
