EN3C3M Equivalent & Substitute Parts

Part Overview

The EN3C3M is a 3-position circular connector plug with male pins and solder cup termination, manufactured by Switchcraft Inc. as part of the EN3® series. This connector is designed for general purpose, instrumentation, marine, and medical applications requiring IP66/IP68 ingress protection and bayonet lock fastening.

The EN3C3M is classified as obsolete. Locating active production alternatives is necessary to ensure supply chain continuity and access to current manufacturing stock for new designs and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EN3C3M is based on electrical and mechanical compatibility across the following critical parameters:

• Connector Configuration: Plug with male pins, 3-position arrangement
• Termination Method: Solder cup for direct wire attachment
• Fastening Mechanism: Bayonet lock coupling
• Keying System: Keyed orientation to prevent mating errors
• Contact Material and Finish: Copper alloy with gold mating surface for corrosion resistance
• Environmental Rating: IP66/IP68 dust-tight and waterproof performance
• Electrical Specifications: 7.5A current capacity and 250VAC/DC voltage rating
• Temperature Range: -40°C to 65°C operational limits
• Cable Accommodation: 0.160" to 0.265" cable diameter range

The EN3C3MX is a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The EN3C3MX is the direct equivalent for the EN3C3M. Both connectors are manufactured by Switchcraft Inc. within the EN3® series and maintain identical electrical and mechanical specifications across all critical parameters.

The EN3C3MX offers the advantage of active product status, ensuring ongoing manufacturing support and supply chain availability. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and medical applications.

Selection between these parts should be based on supply availability and project timeline requirements. The EN3C3MX is recommended for new designs and applications requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can EN3C3MX be used as a direct replacement for EN3C3M in existing assemblies?

A: Yes. The EN3C3MX maintains identical electrical ratings (7.5A, 250VAC/DC), mechanical configuration (3-position plug with bayonet lock), termination method (solder cup), and environmental protection (IP66/IP68). Physical dimensions and mating interfaces are equivalent.

Q: What is the difference between EN3C3M and EN3C3MX?

A: The primary difference is product status. EN3C3M is obsolete, while EN3C3MX is active production. All electrical, mechanical, and compliance specifications are identical.

Q: Are there packaging differences between EN3C3M and EN3C3MX?

A: EN3C3M is supplied in standard packaging, while EN3C3MX is available in bulk packaging. This does not affect connector performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EN3C3M and EN3C3MX are ROHS3 compliant, REACH unaffected, and carry EAR99 export classification. Both meet UL94 V-0 flammability requirements.

Q: What cable sizes are compatible with these connectors?

A: Both connectors accommodate cable diameters from 0.160" to 0.265" (4.06mm to 6.73mm) through the cable opening.

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

A: Yes. Both EN3C3M and EN3C3MX are rated for general purpose, instrumentation, marine, and medical applications with IP66/IP68 ingress protection.
