EN2C3M20G2W Equivalent & Substitute Parts

Part Overview

The EN2C3M20G2W is a 3-position circular connector plug manufactured by Switchcraft Inc. as part of the EN2™ series. This male pin connector features crimp or solder cup termination, bayonet lock fastening, and gold-plated mating contacts. The connector is rated for 2A at 125VAC/DC and operates across -40°C to 85°C, with IP66/IP67/IP68 ingress protection suitable for communication systems, industrial, marine, and medical applications. As an active product with 697 units in stock, equivalent alternatives may be required for supply chain optimization, design flexibility, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EN2C3M20G2W is evaluated based on core electrical and mechanical compatibility parameters. The substitute part 21031111305 (HARTING Harax® M12-S) shares the following critical attributes with the main part:

• 3-position male pin connector configuration
• Gold-plated mating contacts
• Free hanging (in-line) mounting type
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and REACH unaffected status
• Identical HTSUS classification (8536.69.4020)

However, substitution introduces differences in termination method (IDC versus crimp/solder cup), fastening mechanism (threaded versus bayonet lock), current rating (4A versus 2A), voltage rating (32V versus 125VAC/DC), and ingress protection level (IP65/IP67 versus IP66/IP67/IP68). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the EN2C3M20G2W and 21031111305 maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between these parts depends on application-specific electrical and mechanical requirements:

The EN2C3M20G2W is appropriate for applications requiring bayonet lock coupling, crimp or solder cup termination compatibility, 125VAC/DC voltage operation, and IP66/IP67/IP68 environmental sealing.

The 21031111305 is appropriate for applications compatible with threaded coupling, IDC termination, 32V maximum voltage operation, and IP65/IP67 environmental sealing. The higher current rating (4A) accommodates applications with greater current demands within the 32V constraint.

Direct substitution requires verification that the receiving application can accommodate differences in fastening mechanism, termination method, voltage rating, and ingress protection level.

Frequently Asked Questions (FAQ)

Q: Can the 21031111305 directly replace the EN2C3M20G2W in existing designs?

A: Direct replacement requires design modification. The parts differ in fastening type (threaded versus bayonet lock), termination method (IDC versus crimp/solder cup), and voltage rating (32V versus 125VAC/DC). Mechanical and electrical compatibility must be verified for the specific application.

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

A: The EN2C3M20G2W uses crimp or solder cup termination, allowing field assembly with standard crimping tools or soldering equipment. The 21031111305 uses IDC (insulation displacement contact) termination, which requires IDC-compatible cable and tooling.

Q: Are both connectors suitable for marine and medical applications?

A: The EN2C3M20G2W explicitly lists marine and medical applications. The 21031111305 does not specify application categories in the provided data. Application suitability must be confirmed through the manufacturer's documentation and compliance certifications for the intended use.

Q: What is the significance of the ingress protection rating difference?

A: The EN2C3M20G2W provides IP66/IP67/IP68 protection (dust tight, water resistant, waterproof). The 21031111305 provides IP65/IP67 protection (dust tight, water resistant, waterproof). The EN2C3M20G2W offers higher dust ingress protection (IP66 versus IP65).

Q: Can the 21031111305 handle the same voltage as the EN2C3M20G2W?

A: No. The EN2C3M20G2W is rated for 125VAC/DC, while the 21031111305 is rated for 32V maximum. The 21031111305 cannot be used in applications requiring 125VAC/DC operation.

Q: Are both connectors available in the same packaging format?

A: Both parts are supplied in bulk packaging. Inventory availability differs: EN2C3M20G2W has 697 units in stock, while 21031111305 has 956 units in stock.
