EN3P5MPX Equivalent & Substitute Parts

Part Overview

The EN3P5MPX is a 5-position circular connector receptacle manufactured by Switchcraft Inc. under the EN3® series. This component features male pins with solder termination, panel mount through-hole installation, and bayonet lock fastening. The connector is rated for 7.5A at 250VAC/DC with IP66/IP68 ingress protection, making it suitable for general purpose, instrumentation, marine, and medical applications. As an active product with ROHS3 compliance and UL94 V-0 flammability rating, substitute parts may be required due to inventory constraints, application-specific requirements, or design modifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 8-1437719-7 (TE Connectivity AMP Connectors, TRIAD01 series) shares the following critical parameters with the EN3P5MPX:

• 5-position circular connector configuration
• Male pin connector type
• Solder termination method
• Panel mount installation
• Keyed orientation
• Bayonet/threaded fastening mechanism
• EAR99 ECCN classification
• HTSUS code 8536.69.4020

However, substitution compatibility is limited by significant differences in electrical ratings, ingress protection, and mechanical specifications. The 8-1437719-7 operates at lower current (3A vs. 7.5A) and voltage (60VAC vs. 250VAC/DC) ratings, provides reduced ingress protection (IP65 vs. IP66/IP68), and operates across a wider temperature range (-40°C ~ 85°C vs. -40°C ~ 65°C). These differences restrict substitution to applications with lower electrical demands and less stringent environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the EN3P5MPX and 8-1437719-7 maintain active product status with current RoHS compliance certifications. The EN3P5MPX achieves UL94 V-0 flammability rating, while the 8-1437719-7 meets UL94 V-2 standards. Selection between these components must be based on application electrical requirements. The EN3P5MPX is suitable for applications requiring 7.5A at 250VAC/DC with enhanced environmental sealing (IP66/IP68). The 8-1437719-7 is limited to applications with maximum 3A at 60VAC and reduced ingress protection (IP65). Connector type differences (receptacle vs. plug) and fastening mechanism variations (bayonet vs. threaded) must be evaluated against specific installation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 8-1437719-7 directly replace the EN3P5MPX in all applications?

A: No. The 8-1437719-7 has significantly lower electrical ratings (3A at 60VAC vs. 7.5A at 250VAC/DC) and reduced ingress protection (IP65 vs. IP66/IP68). Substitution is only viable for applications with lower power requirements and less stringent environmental conditions.

Q: What are the key differences in connector configuration?

A: The EN3P5MPX is a receptacle with male pins and bayonet lock fastening. The 8-1437719-7 is a plug with male pins and threaded fastening. These structural differences affect mating compatibility and installation methods.

Q: Are both parts RoHS compliant?

A: Yes. The EN3P5MPX is ROHS3 compliant, and the 8-1437719-7 is RoHS compliant. Both meet current regulatory requirements.

Q: What is the impact of different termination methods?

A: The EN3P5MPX uses standard solder termination, while the 8-1437719-7 uses solder cup termination. Both are solder-based methods suitable for PCB assembly, with solder cup providing a defined solder reservoir.

Q: How do operating temperature ranges affect substitution?

A: The EN3P5MPX operates from -40°C to 65°C, while the 8-1437719-7 operates from -40°C to 85°C. The substitute part supports higher maximum temperatures but both share the same minimum operating temperature.

Q: What packaging considerations apply to these parts?

A: Both components are supplied in bulk packaging. Inventory availability differs: EN3P5MPX has 944 pieces in stock, while 8-1437719-7 has 1420 pieces in stock.
