EN3C6F Equivalent & Substitute Parts

Part Overview

The EN3C6F is a 6-position circular connector plug with female sockets 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 EN3C6F 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 EN3C6FX qualifies as a direct substitute for the EN3C6F based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Same connector type (Plug, Female Sockets)
• Same number of positions (6)
• Same termination method (Solder Cup)
• Same fastening mechanism (Bayonet Lock)
• Same keyed orientation
• Identical contact finish (Gold)
• Identical ingress protection rating (IP66/IP68)
• Identical current and voltage ratings (7.5A, 250VAC/DC)
• Compatible operating temperature range (-40°C ~ 65°C)
• Compatible cable opening specifications (0.160" ~ 0.265")
• Equivalent material and flammability compliance (UL94 V-0)

The EN3C6FX maintains full compatibility with applications and mounting configurations of the EN3C6F while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The EN3C6FX is the appropriate selection for applications currently specified with EN3C6F. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status. ROHS3 compliance and REACH unaffected status are preserved in the substitute, ensuring regulatory continuity for applications in general purpose, instrumentation, marine, and medical environments.

The transition from EN3C6F to EN3C6FX does not require design modifications or re-qualification of existing assemblies, as all functional parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can EN3C6FX be used as a direct replacement for EN3C6F in existing designs?

A: Yes. The EN3C6FX maintains identical electrical ratings (7.5A, 250VAC/DC), mechanical configuration (6-position, bayonet lock, keyed orientation), termination method (solder cup), and environmental protection (IP66/IP68). No design changes are required.

Q: What is the primary difference between EN3C6F and EN3C6FX?

A: The EN3C6F is obsolete, while EN3C6FX is an active product. Both parts are manufactured by Switchcraft Inc. within the EN3® series and share identical specifications.

Q: Are there packaging differences between these parts?

A: The EN3C6F was supplied in standard packaging, while EN3C6FX is available in bulk packaging. This difference does not affect connector performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EN3C6F and EN3C6FX are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability.

Q: What cable opening range is supported?

A: Both connectors support cable openings from 0.160" to 0.265" (4.06mm to 6.73mm), ensuring compatibility with standard cable assemblies.

Q: Are there temperature limitations for these connectors?

A: Both parts operate within the range of -40°C to 65°C, suitable for general purpose, instrumentation, marine, and medical applications.
