Key Parameters

Substitute Part Grouping Explanation

Substitution of the EN3P3F is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 3
• Mounting configuration: Panel mount with bulkhead front side nut
• Termination method: Solder cup
• Fastening mechanism: Bayonet lock with keyed orientation
• Electrical ratings: 7.5A current, 250VAC/DC voltage
• Environmental protection: IP66/IP68 ingress protection
• Contact finish: Gold plating on mating surfaces
• Compliance: ROHS3 and REACH requirements

The EN3P3FX qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The primary distinction is product status: EN3P3FX is active production, whereas EN3P3F is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EN3P3FX is the direct equivalent for the obsolete EN3P3F. Both components maintain identical electrical performance (7.5A at 250VAC/DC), mechanical configuration (3-position bayonet lock receptacle), and environmental ratings (IP66/IP68, UL94 V-0). Both satisfy ROHS3 and REACH compliance requirements.

Selection of EN3P3FX over EN3P3F is justified by active production status, ensuring long-term supply availability and consistent manufacturing quality. The MSL rating difference (Not Applicable vs. 1 - Unlimited) reflects standard documentation practices and does not affect component functionality or storage requirements for this connector type.

Frequently Asked Questions (FAQ)

Q: Can EN3P3FX directly replace EN3P3F in existing designs?

A: Yes. The EN3P3FX is electrically and mechanically identical to EN3P3F. All electrical ratings, connector geometry, mounting configuration, and environmental protection specifications are equivalent. Direct substitution is appropriate for new production and field replacement applications.

Q: Why is EN3P3F listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. EN3P3FX represents the current production equivalent within the EN3® series, ensuring continued availability and supply chain stability.

Q: Are there packaging differences between EN3P3F and EN3P3FX?

A: EN3P3FX is supplied in bulk packaging, whereas EN3P3F packaging is not specified in available documentation. This distinction does not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EN3P3F and EN3P3FX are ROHS3 compliant and REACH unaffected. Both carry UL94 V-0 material flammability ratings and meet IP66/IP68 ingress protection requirements.

Q: What is the MSL difference between these parts?

A: EN3P3F lists MSL as Not Applicable, while EN3P3FX specifies MSL 1 (Unlimited). For circular connectors with solder cup termination, this difference reflects documentation conventions and does not impact storage, handling, or operational characteristics.
