Key Parameters

Substitute Part Grouping Explanation

The EN3L5M has one direct equivalent substitute: EN3L5MX. This substitution is valid based on the following matching parameters:

• Identical connector type (Receptacle, Male Pins)
• Identical number of positions (5)
• Identical termination method (Solder Cup)
• Identical fastening type (Bayonet Lock)
• Identical current rating (7.5A)
• Identical voltage rating (250VAC/DC)
• Identical contact finish (Gold)
• Identical ingress protection rating (IP66/IP68)
• Identical operating temperature range (-40°C ~ 65°C)
• Identical series designation (EN3®)
• Identical RoHS compliance status (ROHS3 Compliant)

The primary distinction is product status: EN3L5M is obsolete, while EN3L5MX is active.

Parameter Comparison

Engineering Selection Recommendations

The EN3L5MX is the direct active equivalent for the obsolete EN3L5M. Both components are manufactured by Switchcraft Inc. within the EN3® series and maintain identical electrical and mechanical specifications. The EN3L5MX carries ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. Selection of EN3L5MX eliminates obsolescence risk while preserving full functional compatibility with existing designs utilizing the EN3L5M.

Frequently Asked Questions (FAQ)

Q: Can EN3L5MX be used as a direct replacement for EN3L5M in existing designs?

A: Yes. The EN3L5MX is electrically and mechanically identical to the EN3L5M across all specified parameters, including connector type, pin count, termination method, current and voltage ratings, contact finish, and ingress protection rating.

Q: What is the primary reason for substituting EN3L5M with EN3L5MX?

A: The EN3L5M is classified as obsolete. The EN3L5MX is the active equivalent part from the same manufacturer and series, ensuring continued availability and supply chain stability.

Q: Are there packaging differences between EN3L5M and EN3L5MX?

A: The EN3L5M is supplied in standard packaging, while EN3L5MX is supplied in bulk packaging. This distinction does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EN3L5M and EN3L5MX are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8536.69.4020.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -40°C to 65°C, suitable for general purpose, instrumentation, marine, and medical applications.

Q: Are these connectors shielded?

A: No. Both EN3L5M and EN3L5MX are unshielded circular connectors with bayonet lock fastening and keyed orientation.
