Key Parameters

Substitute Part Grouping Explanation

Substitution of the EN3P4M is based on electrical and mechanical parameter equivalence within the EN3® series. The substitute part EN3P4MX maintains identical specifications across all critical parameters that define connector functionality and compatibility:

• Connector configuration: 4-position receptacle with male pins
• Electrical performance: 7.5A current rating, 250VAC/DC voltage rating
• Mechanical interface: Bayonet lock fastening, panel mount with bulkhead front-side nut
• Termination: Solder cup
• Environmental protection: IP66/IP68 ingress protection
• Material and safety compliance: Thermoplastic shell, UL94 V-0 flammability rating, ROHS3 compliant

The primary distinction between EN3P4M and EN3P4MX is product status and packaging configuration. EN3P4MX is active production status with bulk packaging, whereas EN3P4M is obsolete.

Parameter Comparison

Engineering Selection Recommendations

EN3P4MX is the direct substitute for EN3P4M. Both parts are manufactured by Switchcraft Inc. within the EN3® series and share identical electrical, mechanical, and environmental specifications. The EN3P4MX is the preferred selection for new designs and component replacement due to its active production status, ensuring long-term availability and supply chain stability.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The gold-plated copper alloy contacts and UL94 V-0 thermoplastic shell provide equivalent performance characteristics across all specified applications including general purpose, instrumentation, marine, and medical use cases.
