EN3L3MCX Equivalent & Substitute Parts Reference
Part Overview
The EN3L3MCX is a 3-position circular connector receptacle manufactured by Switchcraft Inc. under the EN3® series. This component features male pins with crimp termination, bayonet locking, and gold-plated mating contacts. The connector is rated for 7.5A at 250VAC/DC and meets IP66/IP68 ingress protection standards, making it suitable for general purpose, instrumentation, marine, and medical applications. As an active product with full stock availability, equivalent alternatives may be required for design flexibility, supply chain optimization, or specific application requirements where substitute connectors meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution eligibility for the EN3L3MCX is determined by the following critical parameters:
- Connector Configuration: 3-position circular connector with male pins
- Termination Method: Crimp contact termination
- Electrical Performance: Minimum 7.5A current rating and 250VAC/DC voltage rating
- Mechanical Interface: Free hanging (in-line) mounting with keyed orientation
- Environmental Protection: IP65 or higher ingress protection rating
- Regulatory Compliance: ROHS3 compliance and EAR99 classification
- Operating Range: Temperature range of -40°C or lower to 65°C or higher
The substitute part 1-1437719-1 (TE Connectivity AMP Connectors, TRIAD01 series) qualifies as an equivalent based on matching connector position count, crimp termination, free hanging mounting, keyed orientation, and regulatory compliance. Both parts are classified under HTSUS 8536.69.4020 and maintain EAR99 export control status.

Engineering Selection Recommendations
Both the EN3L3MCX and 1-1437719-1 maintain active product status and full ROHS3 compliance, qualifying them for applications requiring regulatory adherence. The EN3L3MCX provides IP66/IP68 protection with bayonet fastening, while the 1-1437719-1 offers IP65 protection with threaded fastening and an extended upper operating temperature of 80°C. Selection between these parts should be based on specific application requirements regarding ingress protection level, fastening mechanism preference, and thermal operating conditions. Both parts are classified under identical HTSUS and ECCN codes, ensuring consistent export and import treatment.
Frequently Asked Questions (FAQ)
Q: Can the 1-1437719-1 directly replace the EN3L3MCX in all applications?
A: Both connectors share 3-position configuration, crimp termination, free hanging mounting, and keyed orientation. However, the EN3L3MCX provides higher ingress protection (IP66/IP68 versus IP65) and uses bayonet fastening, while the 1-1437719-1 uses threaded fastening. Application-specific requirements for sealing and mechanical coupling must be evaluated.
Q: What are the key differences in fastening mechanisms?
A: The EN3L3MCX employs bayonet lock fastening, while the 1-1437719-1 uses threaded coupling. These represent different mechanical interfaces and are not interchangeable without adapter consideration.
Q: Are both parts suitable for marine and medical applications?
A: The EN3L3MCX is explicitly rated for marine and medical applications. The 1-1437719-1 application scope is not specified in the provided data. Application suitability must be confirmed against specific end-use requirements.
Q: What is the significance of the ingress protection rating difference?
A: The EN3L3MCX provides IP66/IP68 protection (dust tight, waterproof), while the 1-1437719-1 provides IP65 protection (dust tight, water resistant). Applications requiring full waterproof sealing should specify the EN3L3MCX.
Q: Are both parts RoHS compliant?
A: Yes, both the EN3L3MCX and 1-1437719-1 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.
Q: What is the contact size specification for the 1-1437719-1?
A: The 1-1437719-1 specifies a 1.0mm contact size. The EN3L3MCX contact size is not provided in the reference data.
