EN3C4F Equivalent & Substitute Parts

Part Overview

The EN3C4F is a 4-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 EN3C4F is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

The EN3C4FX qualifies as a direct substitute for the EN3C4F 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 (4)
• Same termination method (Solder Cup)
• Same fastening type (Bayonet Lock)
• Same orientation (Keyed)
• Same contact finish (Gold)
• Same ingress protection rating (IP66/IP68)
• Same current and voltage ratings (7.5A, 250VAC/DC)
• Same cable opening range (0.160" ~ 0.265")
• Same operating temperature range (-40°C ~ 65°C)
• Same material flammability rating (UL94 V-0)
• Same RoHS compliance status (ROHS3 Compliant)

The EN3C4FX maintains full compatibility with applications designed for the EN3C4F while offering the advantage of active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The EN3C4FX is the appropriate selection for new designs and procurement activities. As an active product with identical electrical and mechanical specifications to the obsolete EN3C4F, it provides direct compatibility without design modification. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The EN3C4FX offers superior supply chain continuity with 4356 units in stock compared to the EN3C4F's 821 units.

Frequently Asked Questions (FAQ)

Q: Can EN3C4FX be used as a direct replacement for EN3C4F in existing assemblies?

A: Yes. The EN3C4FX maintains 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). No circuit or mechanical modifications are required.

Q: What is the difference between EN3C4F and EN3C4FX?

A: The primary difference is product status. EN3C4F is obsolete while EN3C4FX is active. Packaging differs (EN3C4F is unspecified; EN3C4FX is bulk). All functional and electrical parameters are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same UL94 V-0 flammability rating. Export classification (EAR99) and tariff codes (8536.69.4020) are identical.

Q: Which part should be specified for new designs?

A: EN3C4FX should be specified for new designs due to its active product status and established supply chain availability.

Q: Are the cable opening specifications identical?

A: Yes. Both parts accept cables with outer diameters from 0.160" to 0.265" (4.06mm to 6.73mm).
