EN3P3M Circular Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The EN3P3M is a 3-position circular connector receptacle with male pins, manufactured by Switchcraft Inc. as part of the EN3® series. This component features solder cup termination, panel mount configuration with bayonet lock fastening, and is rated for 7.5A at 250VAC/DC. The EN3P3M is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance in applications requiring circular connector receptacles with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The EN3P3M has one direct equivalent substitute: EN3P3MX. Substitution is based on identical electrical and mechanical parameters across all critical specifications. Both parts share the same connector architecture, pin configuration, termination method, and performance ratings. The substitution is valid because the following key parameters are identical:

• Connector type: Receptacle, Male Pins
• Number of positions: 3
• Mounting configuration: Panel Mount, Bulkhead - Front Side Nut
• Termination method: Solder Cup
• Fastening mechanism: Bayonet Lock
• Orientation: Keyed
• Current rating: 7.5A
• Voltage rating: 250VAC/DC
• Operating temperature range: -40°C ~ 65°C
• Ingress protection: IP66/IP68
• Material flammability: UL94 V-0
• Contact finish: Gold
• Shell material: Thermoplastic
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Parameter Comparison

Engineering Selection Recommendations

The EN3P3MX is the direct active equivalent for the obsolete EN3P3M. Both components maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The EN3P3MX is manufactured by the same supplier (Switchcraft Inc.) within the same EN3® series and carries active product status, ensuring ongoing availability and supply chain continuity.

Selection of EN3P3MX over EN3P3M is based on product lifecycle status. The EN3P3M is classified as obsolete, while EN3P3MX is active. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The EN3P3MX is supplied in bulk packaging, which may differ from the original EN3P3M packaging specification.

Frequently Asked Questions (FAQ)

Q: Can EN3P3MX be used as a direct replacement for EN3P3M?

A: Yes. EN3P3MX is the direct equivalent substitute for EN3P3M. All electrical parameters, mechanical dimensions, termination methods, and performance ratings are identical. Both components are 3-position circular connector receptacles with male pins, solder cup termination, bayonet lock fastening, and identical current and voltage ratings.

Q: What is the difference between EN3P3M and EN3P3MX?

A: The primary difference is product status. EN3P3M is obsolete, while EN3P3MX is active. EN3P3MX is supplied in bulk packaging. Both parts are manufactured by Switchcraft Inc. and share identical specifications for connector type, pin configuration, mounting configuration, termination, fastening, ingress protection, and regulatory compliance.

Q: Are there any compatibility concerns when substituting EN3P3M with EN3P3MX?

A: No compatibility concerns exist. The parts are electrically and mechanically identical. Both support the same applications: General Purpose, Instrumentation, Marine, and Medical. Both operate across the same temperature range (-40°C ~ 65°C) and maintain the same IP66/IP68 ingress protection rating.

Q: What is the current availability status of these parts?

A: EN3P3M is obsolete with 715 pieces in stock. EN3P3MX is active with 2,369 pieces in stock. For new designs and ongoing procurement, EN3P3MX should be specified.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both EN3P3M and EN3P3MX are ROHS3 compliant and REACH unaffected. Both carry UL94 V-0 material flammability rating and are classified under ECCN EAR99 and HTSUS code 8536.69.4020.

Q: What applications are these connectors suitable for?

A: Both parts are rated for General Purpose, Instrumentation, Marine, and Medical applications. The IP66/IP68 ingress protection rating and UL94 V-0 flammability rating support use in environments requiring dust-tight and water-resistant performance.
