EN3C5M Equivalent & Substitute Parts

Part Overview

The EN3C5M is a 5-position circular connector plug with male pins and solder cup termination, manufactured by Switchcraft Inc. as part of the EN3® series. This connector is designed for general purpose, instrumentation, marine, and medical applications requiring IP66/IP68 ingress protection and bayonet lock fastening. The EN3C5M is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The EN3C5M has one direct substitute within the EN3® series: EN3C5MX. Substitution is valid based on the following criteria:

Electrical Parameters (Must Match):

• Number of positions: 5
• Connector type: Plug, Male Pins
• Current rating: 7.5A
• Voltage rating: 250VAC/DC
• Contact finish: Gold

Mechanical Parameters (Must Match):

• Fastening type: Bayonet Lock
• Orientation: Keyed
• Termination: Solder Cup
• Cable opening range: 0.160" ~ 0.265" (4.06mm ~ 6.73mm)
• Ingress protection: IP66/IP68

Environmental & Compliance Parameters (Must Match):

• Operating temperature: -40°C ~ 65°C
• Material flammability: UL94 V-0
• RoHS status: ROHS3 Compliant

The EN3C5MX maintains identical electrical, mechanical, and environmental specifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The EN3C5MX is the direct substitute for the obsolete EN3C5M. Both parts are manufactured by Switchcraft Inc. within the same EN3® series and maintain identical electrical, mechanical, and environmental specifications. The EN3C5MX offers the advantage of active product status, ensuring long-term availability and supply chain continuity. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The EN3C5MX is available in bulk packaging with significantly higher inventory levels (6109 units versus 925 units for the EN3C5M), supporting both new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can EN3C5MX be used as a direct replacement for EN3C5M? A: Yes. The EN3C5MX is electrically and mechanically identical to the EN3C5M, with matching pin count, current rating, voltage rating, termination type, fastening mechanism, and ingress protection rating. Both parts are compatible with the same mating connectors and cable specifications.

Q: What is the primary difference between EN3C5M and EN3C5MX? A: The EN3C5M is obsolete, while the EN3C5MX is an active product. The EN3C5MX also offers improved inventory availability and is supplied in bulk packaging.

Q: Are there any packaging differences between these parts? A: The EN3C5M is supplied with standard packaging, while the EN3C5MX is supplied in bulk packaging. This does not affect the connector's electrical or mechanical performance.

Q: Do both parts meet the same compliance standards? A: Yes. Both EN3C5M and EN3C5MX are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS classifications.

Q: What cable opening range is supported by these connectors? A: Both connectors support cable openings from 0.160" to 0.265" (4.06mm to 6.73mm), accommodating standard cable diameters for this connector class.

Q: Are these connectors suitable for marine and medical applications? A: Yes. Both parts are rated for general purpose, instrumentation, marine, and medical applications with IP66/IP68 ingress protection and UL94 V-0 flammability rating.
