Substitute Part Grouping Explanation

The EN3L3FX qualifies as a direct substitute for the EN3L3F based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type: Receptacle, Female Sockets (identical)
• Number of positions: 3 (identical)
• Termination method: Solder Cup (identical)
• Fastening mechanism: Bayonet Lock (identical)
• Contact finish: Gold plating (identical)
• Current and voltage ratings: 7.5A at 250VAC/DC (identical)
• Operating temperature range: -40°C ~ 65°C (identical)
• Ingress protection rating: IP66/IP68 (identical)
• Series compatibility: EN3® (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The primary distinction between these parts is product status and packaging configuration. The EN3L3FX is an active product available in bulk packaging, whereas the EN3L3F is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EN3L3FX is the appropriate substitute for the EN3L3F in all applications where the obsolete part was previously specified. Both components maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The EN3L3FX carries active product status with established supply availability, eliminating obsolescence risk associated with the EN3L3F. Both parts satisfy ROHS3 compliance requirements and REACH regulatory obligations. Selection of the EN3L3FX ensures continuity of connector performance across general purpose, instrumentation, marine, and medical applications while maintaining full compatibility with existing mating connectors and cable assemblies designed for the EN3® series.

Frequently Asked Questions (FAQ)

Q: Can EN3L3FX be used as a direct replacement for EN3L3F in existing assemblies?

A: Yes. The EN3L3FX is electrically and mechanically identical to the EN3L3F. All electrical ratings, contact configurations, fastening mechanisms, and environmental specifications are equivalent. Existing mating connectors and cable assemblies designed for EN3L3F will function identically with EN3L3FX.

Q: What is the primary reason to transition from EN3L3F to EN3L3FX?

A: The EN3L3F is classified as obsolete, while the EN3L3FX maintains active product status. Transitioning to EN3L3FX ensures long-term supply availability and eliminates the risk of component discontinuation.

Q: Are there any differences in packaging between these parts?

A: The EN3L3F packaging specification is not provided in the technical data. The EN3L3FX is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both EN3L3F and EN3L3FX are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry UL94 V-0 material flammability ratings and identical HTSUS classification.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -40°C to 65°C.

Q: What cable opening dimensions are supported?

A: Both parts support cable openings from 0.160" to 0.265" (4.06mm to 6.73mm).
