EN3P6F Circular Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The EN3P6F is a 6-position circular connector receptacle with female sockets, manufactured by Switchcraft Inc. as part of the EN3® series. This component features solder cup termination, bayonet lock fastening, and gold-plated contacts rated for 7.5A at 250VAC/DC. The EN3P6F is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance in applications requiring panel-mount circular connectors with IP66/IP68 ingress protection.

Key Parameters

Substitute Part Grouping Explanation

The EN3P6F has one direct equivalent substitute: EN3P6FX. This substitution is valid based on identical electrical and mechanical parameters across all critical specifications. Both parts maintain the same connector architecture, contact configuration, and performance ratings. The substitution is justified by matching the following key parameters:

• 6-position female socket receptacle configuration
• Solder cup termination with identical contact material (copper alloy) and finish (gold)
• Bayonet lock fastening mechanism with keyed orientation
• Panel mount bulkhead installation with front side nut
• Identical current (7.5A) and voltage (250VAC/DC) ratings
• Matching ingress protection (IP66/IP68) and temperature range (-40°C to 65°C)
• Equivalent material specifications (thermoplastic shell, UL94 V-0 flammability rating)
• Identical regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The primary distinction between these parts is product status and packaging: EN3P6F is obsolete, while EN3P6FX is active with bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

EN3P6FX is the direct active equivalent for EN3P6F applications. Selection of EN3P6FX is supported by:

• Identical electrical performance specifications (7.5A, 250VAC/DC)
• Matching mechanical interface and mounting configuration
• Equivalent environmental ratings (IP66/IP68, -40°C to 65°C operating range)
• Active product status with current manufacturing support
• Identical regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Bulk packaging availability for production quantities

For systems currently using EN3P6F, transition to EN3P6FX requires no design modifications. Pin configuration, contact arrangement, and mechanical fit remain unchanged. Solder cup termination is identical, allowing direct substitution in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can EN3P6FX be used as a direct replacement for EN3P6F?

A: Yes. EN3P6FX is a direct equivalent substitute. All electrical ratings, mechanical dimensions, contact configurations, and environmental specifications are identical. The primary difference is product status: EN3P6F is obsolete while EN3P6FX is active.

Q: What is the difference between EN3P6F and EN3P6FX?

A: Both parts are 6-position female socket receptacles from the EN3® series with identical specifications. EN3P6F is classified as obsolete, while EN3P6FX is an active product with bulk packaging. No functional or performance differences exist between these parts.

Q: Are there any compatibility concerns when switching from EN3P6F to EN3P6FX?

A: No compatibility concerns exist. Both parts feature identical bayonet lock fastening, keyed orientation, solder cup termination, and panel mount bulkhead installation. Existing designs require no modification.

Q: What packaging options are available for EN3P6FX?

A: EN3P6FX is supplied in bulk packaging. Inventory availability is 1954 pieces in new original condition.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both EN3P6F and EN3P6FX are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry UL94 V-0 flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: EN3P6F lists moisture sensitivity as not applicable. EN3P6FX specifies MSL 1 (unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these connectors suitable for marine and medical applications?

A: Yes. Both EN3P6F and EN3P6FX are rated for general purpose, instrumentation, marine, and medical applications with IP66/IP68 ingress protection and -40°C to 65°C operating temperature range.
