EN3P4F Equivalent & Substitute Parts

Part Overview

The EN3P4F is a 4-position circular connector receptacle manufactured by Switchcraft Inc. as part of the EN3® series. This female socket connector features solder cup termination, bayonet lock fastening, and gold-plated contacts rated for 7.5A at 250VAC/DC. The connector is designed for panel mount applications with bulkhead front-side nut mounting and provides IP66/IP68 ingress protection suitable for general purpose, instrumentation, marine, and medical applications.

The EN3P4F is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EN3P4F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Number of positions (4)
• Termination method (Solder Cup)
• Fastening mechanism (Bayonet Lock)
• Mounting configuration (Panel Mount, Bulkhead - Front Side Nut)
• Electrical ratings (7.5A, 250VAC/DC)
• Contact finish (Gold)
• Ingress protection level (IP66/IP68)
• Operating temperature range (-40°C ~ 65°C)
• Compliance certifications (ROHS3, UL94 V-0)

The EN3P4FX is identified as a direct substitute based on identical values across all these parameters. The primary distinction is product status: EN3P4F is obsolete while EN3P4FX is active, with EN3P4FX available in bulk packaging and higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

The EN3P4FX is the direct equivalent substitute for the EN3P4F. Both parts maintain identical electrical, mechanical, and environmental specifications. The EN3P4FX is the preferred selection due to its active product status, ensuring ongoing manufacturer support and availability. The EN3P4FX is supplied in bulk packaging with significantly higher inventory levels (1394 units versus 757 units for EN3P4F), supporting both new designs and replacement applications.

Both parts satisfy ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment for applications in general purpose, instrumentation, marine, and medical sectors.

Frequently Asked Questions (FAQ)

Q: Can EN3P4FX directly replace EN3P4F in existing designs? A: Yes. The EN3P4FX is electrically and mechanically equivalent to EN3P4F across all specified parameters, including connector type, pin count, termination method, electrical ratings, and environmental protection ratings.

Q: What is the primary reason to transition from EN3P4F to EN3P4FX? A: The EN3P4F is classified as obsolete, while EN3P4FX is an active product. Transitioning to EN3P4FX ensures continued supply chain access and manufacturer support.

Q: Are there packaging differences between these parts? A: EN3P4F is supplied with standard packaging, while EN3P4FX is supplied in bulk packaging. Both contain identical connector specifications.

Q: Do both parts meet the same compliance standards? A: Yes. Both EN3P4F and EN3P4FX are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability.

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 is the moisture sensitivity level difference? A: EN3P4F lists MSL as Not Applicable, while EN3P4FX specifies MSL 1 (Unlimited). This indicates EN3P4FX has no moisture sensitivity restrictions during storage and handling.
