Key Parameters

Substitute Part Grouping Explanation

The EN3C3FX qualifies as a direct substitute for the EN3C3F based on identical electrical and mechanical parameters. Both parts share the same connector architecture, pin configuration, and performance specifications. The substitution is valid because the following critical parameters are identical:

• Connector type: Plug with female sockets
• Number of positions: 3
• Termination method: Solder cup
• Fastening mechanism: Bayonet lock
• Current and voltage ratings: 7.5A at 250VAC/DC
• Contact finish: Gold plating
• Ingress protection: IP66/IP68
• Operating temperature range: -40°C ~ 65°C
• Material compliance: UL94 V-0, ROHS3 compliant

The primary distinction is product status: EN3C3F is obsolete while EN3C3FX is active, with EN3C3FX serving as the current production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EN3C3FX is the appropriate selection for new designs and procurement activities. As an active product with identical electrical and mechanical specifications to the obsolete EN3C3F, it provides direct compatibility while ensuring access to current manufacturing and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial, marine, and medical applications.

For existing systems currently using EN3C3F, the EN3C3FX provides seamless integration without circuit redesign or connector interface modification.
