EN3C3MCKX Equivalent & Substitute Parts

Part Overview

The EN3C3MCKX is a 3-position circular connector plug manufactured by Switchcraft Inc. under the EN3® series. This male pin connector features crimp termination, bayonet locking, and gold-plated mating contacts rated for 7.5A at 250VAC/DC. The connector is designed for free-hanging (in-line) applications with IP66/IP68 ingress protection, making it suitable for general purpose, instrumentation, marine, and medical applications. As an active product with full RoHS3 compliance, substitute parts may be required due to inventory constraints, application-specific requirements, or design modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EN3C3MCKX is determined by the following critical parameters:

• Connector Configuration: 3-position circular connector plug with male pins
• Termination Compatibility: Crimp contact termination
• Mounting Profile: Free-hanging (in-line) configuration with backshell and coupling nut
• Electrical Performance: Minimum 7.5A current rating and 250VAC/DC voltage rating
• Environmental Sealing: IP65 or higher ingress protection rating
• Orientation: Keyed connector design
• Compliance: RoHS3 compliance required

The substitute part 1-1437719-1 (TE Connectivity AMP Connectors, TRIAD01 series) qualifies as an equivalent based on matching core functional parameters: 3-position configuration, crimp contact system, free-hanging mounting, keyed orientation, and RoHS3 compliance. However, specific differences in fastening mechanism, ingress protection rating, and operating temperature range must be evaluated for application suitability.

Parameter Comparison

Engineering Selection Recommendations

Both the EN3C3MCKX and 1-1437719-1 are active products with RoHS3 compliance and EAR99 ECCN classification, meeting regulatory requirements for general industrial and commercial applications.

EN3C3MCKX Selection Criteria:

• Applications requiring bayonet-lock fastening mechanism
• Systems demanding IP66/IP68 environmental sealing
• Unshielded signal transmission environments
• Operating temperature range up to 65°C
• Gold-plated contact finish for corrosion resistance

1-1437719-1 Selection Criteria:

• Applications utilizing threaded fastening
• Systems tolerating IP65 ingress protection
• Shielded signal transmission requirements
• Extended operating temperature capability to 80°C
• Applications where contact finish specifications are not critical

Both connectors share identical position count, crimp termination, free-hanging mounting, and keyed orientation. Selection between these parts should be based on fastening mechanism compatibility, environmental sealing requirements, shielding needs, and temperature operating range specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can 1-1437719-1 directly replace EN3C3MCKX in existing designs?

A: Direct replacement requires verification of fastening mechanism compatibility. The EN3C3MCKX uses bayonet locking while 1-1437719-1 uses threaded fastening. Mechanical interface changes may be necessary. Additionally, the reduced ingress protection rating (IP65 vs. IP66/IP68) must be evaluated for environmental exposure conditions.

Q: What are the key differences affecting substitution?

A: Critical differences include fastening type (bayonet vs. threaded), ingress protection rating (IP66/IP68 vs. IP65), shielding configuration (unshielded vs. shielded), and operating temperature upper limit (65°C vs. 80°C). These parameters determine application compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes, both EN3C3MCKX and 1-1437719-1 are RoHS3 compliant and meet REACH requirements for their respective compliance statuses.

Q: Does 1-1437719-1 include contacts?

A: No. The 1-1437719-1 is a plug housing assembly. Contacts must be sourced separately and are not included with this part.

Q: What is the contact size specification for 1-1437719-1?

A: The contact size is specified as 1.0mm for the 1-1437719-1 connector.

Q: Are there packaging differences between these parts?

A: Yes. EN3C3MCKX is supplied in standard packaging, while 1-1437719-1 is supplied in bulk packaging. Inventory availability differs: EN3C3MCKX has 1009 pieces in stock, while 1-1437719-1 has 1169 pieces in stock.
