EN3L4M Circular Connector Equivalent & Substitute Parts

Part Overview

The EN3L4M is a 4-position circular connector receptacle with male pins, manufactured by Switchcraft Inc. as part of the EN3® series. This component features solder cup termination, bayonet lock fastening, and gold-plated contacts rated for 7.5A at 250VAC/DC. The EN3L4M is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and procurement planning. The substitute part EN3L4MX provides functional continuity with identical electrical and mechanical specifications while maintaining active product status.

Substitute Part Grouping Explanation

The EN3L4MX qualifies as a direct substitute for the EN3L4M based on identical alignment across all critical substitution parameters:

Electrical Parameters: Both parts maintain 7.5A current rating and 250VAC/DC voltage rating with gold-plated copper alloy contacts.

Mechanical Parameters: Both feature 4-position configuration, bayonet lock fastening, solder cup termination, and identical cable opening specifications (0.160" ~ 0.265").

Environmental & Compliance Parameters: Both provide IP66/IP68 ingress protection, UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status.

Operational Parameters: Both support identical operating temperature range (-40°C ~ 65°C) and feature identical connector orientation (keyed) and mounting type (free hanging, in-line).

The primary distinction is product status: EN3L4M is obsolete while EN3L4MX maintains active status, with EN3L4MX available in bulk packaging.

Engineering Selection Recommendations

The EN3L4MX is the appropriate selection for new procurement and system continuity. As an active product within the same EN3® series, EN3L4MX maintains full electrical, mechanical, and environmental equivalence to the obsolete EN3L4M. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for applications in general purpose, instrumentation, marine, and medical environments.

The transition from EN3L4M to EN3L4MX does not require design modification. Connector pinout, mating interface, termination method, and performance specifications remain identical. The bulk packaging option for EN3L4MX supports higher-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can EN3L4MX directly replace EN3L4M in existing designs? A: Yes. EN3L4MX provides complete functional and mechanical equivalence. No design changes are required for connector interface, pin configuration, or termination.

Q: What is the primary reason for substitution? A: EN3L4M is classified as obsolete. EN3L4MX maintains active product status and ensures long-term availability and supply chain continuity.

Q: Are the electrical ratings identical? A: Yes. Both parts are rated for 7.5A at 250VAC/DC with gold-plated contacts and identical operating temperature range (-40°C ~ 65°C).

Q: Do both parts meet the same compliance standards? A: Yes. Both EN3L4M and EN3L4MX are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability.

Q: What is the difference in packaging? A: EN3L4M uses standard packaging while EN3L4MX is available in bulk packaging, supporting higher-volume orders.

Q: Are the cable opening specifications the same? A: Yes. Both parts accommodate cable diameters from 0.160" to 0.265" (4.06mm to 6.73mm).

Q: Can EN3L4MX be used in marine and medical applications? A: Yes. EN3L4MX is rated for general purpose, instrumentation, marine, and medical applications with IP66/IP68 ingress protection.
