EN3C4M Equivalent & Substitute Parts

Part Overview

The EN3C4M is a 4-position circular connector plug with male pins and solder cup termination, manufactured by Switchcraft Inc. as part of the EN3® series. This connector is designed for general purpose, instrumentation, marine, and medical applications requiring IP66/IP68 ingress protection and bayonet lock fastening. The EN3C4M is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The EN3C4MX serves as a direct substitute for the EN3C4M based on identical electrical and mechanical parameters. Substitution is valid because both parts share the following critical specifications:

• Connector type: Plug with male pins
• Position count: 4
• Termination method: Solder cup
• Fastening mechanism: Bayonet lock with keyed orientation
• Electrical ratings: 7.5A current, 250VAC/DC voltage
• Ingress protection: IP66/IP68
• Operating temperature range: -40°C ~ 65°C
• Contact material and finish: Copper alloy with gold plating
• Compliance: ROHS3 and REACH unaffected

The primary distinction is product status: EN3C4M is obsolete while EN3C4MX is active, with EN3C4MX available in bulk packaging and higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

The EN3C4MX is the appropriate selection for new designs and procurement activities. As an active product with identical electrical and mechanical specifications to the obsolete EN3C4M, it provides direct functional equivalence while ensuring ongoing manufacturer support and supply chain availability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for general purpose, instrumentation, marine, and medical applications. The EN3C4MX is available in bulk packaging with substantially higher inventory levels, supporting production requirements without supply constraints.

Frequently Asked Questions (FAQ)

Q: Can EN3C4MX be used as a direct replacement for EN3C4M in existing assemblies?

A: Yes. Both connectors share identical electrical ratings (7.5A, 250VAC/DC), mechanical configuration (4-position, bayonet lock, keyed orientation), termination method (solder cup), and environmental specifications (IP66/IP68, -40°C ~ 65°C operating range). Physical dimensions and contact geometry are equivalent.

Q: What is the primary reason to transition from EN3C4M to EN3C4MX?

A: EN3C4M is obsolete while EN3C4MX is an active product. Transitioning to EN3C4MX ensures continued availability, manufacturer support, and compliance with current supply chain standards.

Q: Are there packaging differences between EN3C4M and EN3C4MX?

A: EN3C4M was supplied in standard packaging, while EN3C4MX is available in bulk packaging. This distinction does not affect connector performance or compatibility.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both EN3C4M and EN3C4MX are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.

Q: Are there any electrical or thermal limitations when substituting EN3C4MX for EN3C4M?

A: No. Current rating (7.5A), voltage rating (250VAC/DC), and operating temperature range (-40°C ~ 65°C) are identical across both parts.
