Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete EN3L3M is based on electrical and mechanical parameter equivalence within the EN3® series. The substitute part EN3L3MX maintains identical specifications across all critical parameters: 3-position configuration, male pin receptacle type, solder cup termination, bayonet lock fastening, keyed orientation, 7.5A current rating, 250VAC/DC voltage rating, gold-plated contacts, IP66/IP68 ingress protection, and -40°C to 65°C operating temperature range. Both parts share identical cable opening dimensions, flammability rating, and regulatory compliance status.

The primary distinction is product status: EN3L3M is obsolete while EN3L3MX is active. EN3L3MX is supplied in bulk packaging, whereas EN3L3M packaging information is not specified. Both parts are manufactured by Switchcraft Inc. and are ROHS3 compliant with REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

EN3L3MX is the direct active equivalent for the obsolete EN3L3M. Both parts are manufactured by Switchcraft Inc. within the EN3® series and maintain complete electrical and mechanical parameter equivalence. Selection of EN3L3MX is supported by identical compliance certifications: ROHS3 compliance and REACH unaffected status. The active product status of EN3L3MX ensures ongoing availability and manufacturer support, addressing the procurement constraints associated with the obsolete EN3L3M designation.

Frequently Asked Questions (FAQ)

Q: Can EN3L3MX directly replace EN3L3M in existing applications? A: Yes. EN3L3MX is electrically and mechanically equivalent to EN3L3M across all specified parameters, including connector type, pin configuration, termination method, fastening mechanism, current and voltage ratings, contact finish, and operating temperature range.

Q: What is the primary reason for substitution? A: EN3L3M is classified as obsolete. EN3L3MX is the active equivalent part from the same manufacturer and series, ensuring continued component availability.

Q: Are there any compliance differences between the two parts? A: No. Both EN3L3M and EN3L3MX are ROHS3 compliant and REACH unaffected. Regulatory compliance status is identical.

Q: How do the packaging specifications differ? A: EN3L3M packaging information is not specified in available documentation. EN3L3MX is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are the contact materials and finishes identical? A: Yes. Both parts feature copper alloy contacts with gold plating on mating surfaces, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the ingress protection rating for both parts? A: Both EN3L3M and EN3L3MX are rated IP66/IP68, providing dust-tight and waterproof protection suitable for marine and instrumentation applications.
