Key Parameters

Substitute Part Grouping Explanation

The EN3L5F has one direct substitute within the EN3® series: EN3L5FX. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector type: Receptacle, Female Sockets
• Number of positions: 5
• Termination method: Solder Cup
• Fastening mechanism: Bayonet Lock
• Contact finish: Gold
• Current rating: 7.5A
• Voltage rating: 250VAC/DC
• Operating temperature range: -40°C ~ 65°C
• Ingress protection rating: IP66/IP68
• Material compliance: UL94 V-0, ROHS3 Compliant

The EN3L5FX maintains electrical and mechanical compatibility with the EN3L5F while offering improved availability as an active product with higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

The EN3L5FX is the direct equivalent for the obsolete EN3L5F. Both parts maintain identical electrical specifications, mechanical interfaces, and environmental ratings. The EN3L5FX is preferred for new procurement due to its active product status and significantly higher inventory availability (5057 units versus 1157 units). Both parts satisfy ROHS3 compliance and REACH requirements, making either suitable for regulated applications. The packaging difference (bulk for EN3L5FX versus standard for EN3L5F) does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can EN3L5FX be used as a direct replacement for EN3L5F?

A: Yes. The EN3L5FX is electrically and mechanically identical to the EN3L5F. All critical parameters including connector type, pin count, termination method, contact finish, current and voltage ratings, and operating temperature range are equivalent.

Q: What is the difference between EN3L5F and EN3L5FX?

A: The primary differences are product status and packaging. EN3L5F is obsolete with limited inventory, while EN3L5FX is an active product with higher stock levels. EN3L5FX is supplied in bulk packaging, whereas EN3L5F uses standard packaging. Functionally, both parts are identical.

Q: Are there any compatibility concerns when substituting EN3L5FX for EN3L5F?

A: No compatibility concerns exist. Both parts are from the same EN3® series, feature identical solder cup termination, bayonet lock fastening, and gold-plated contacts. Cable opening specifications and environmental ratings are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EN3L5F and EN3L5FX are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry UL94 V-0 material flammability ratings.

Q: What applications are these connectors suitable for?

A: Both parts are rated for general purpose, instrumentation, marine, and medical applications. The IP66/IP68 ingress protection rating supports use in environments requiring dust-tight and waterproof performance.
