Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1877846-3 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• 6-position connector configuration
• Solder cup termination method
• Male pin connector type
• Copper alloy contact material with gold plating
• Thermoplastic shell construction
• Free hanging in-line mounting
• RoHS compliance status
• MSL 1 moisture sensitivity rating

Substitution Logic:

The EN3C6MX (Switchcraft Inc.) qualifies as a substitute plug connector with matching 6-position solder cup configuration and male pin design. Both connectors feature gold-plated copper alloy contacts, thermoplastic shells, and RoHS compliance. The EN3C6MX operates at 7.5A (exceeding the 6A requirement) and 250VAC/DC (within the 300VAC specification envelope). Operating temperature range differs (-40°C to 65°C versus -50°C to 170°C), representing a narrower operational window.

The EN3L6MX (Switchcraft Inc.) is a receptacle configuration with male pins and solder cup termination. While this part shares the 6-position count, gold-plated copper contacts, thermoplastic construction, and RoHS compliance, the receptacle connector type represents a different mating interface than the plug configuration of the primary part.

Parameter Comparison

Engineering Selection Recommendations

1877846-3 Primary Selection: The TE Connectivity 1877846-3 remains the primary component for applications requiring the full operating temperature range of -50°C to 170°C and 300VAC voltage rating. This part is actively manufactured and maintains RoHS compliance with unlimited moisture sensitivity rating. The Medical CPC series designation indicates optimization for medical device applications.

EN3C6MX Substitution Conditions: The Switchcraft EN3C6MX plug connector serves as a functional substitute when application requirements fall within the narrower operating temperature range of -40°C to 65°C and voltage rating of 250VAC/DC. The higher current rating of 7.5A provides margin above the 6A specification. This part carries ROHS3 compliance and includes enhanced ingress protection (IP66/IP68). The bayonet lock fastening differs from the latch lock mechanism of the primary part. Both parts maintain active product status and unlimited MSL rating.

EN3L6MX Consideration: The Switchcraft EN3L6MX receptacle connector is not a direct substitute for the 1877846-3 plug configuration. This part represents a different mating interface (receptacle versus plug) and is applicable only in applications where receptacle-type connectors are required. The EN3L6MX shares equivalent electrical ratings, temperature limitations, and compliance certifications with the EN3C6MX.

Frequently Asked Questions (FAQ)

Q: Can the EN3C6MX directly replace the 1877846-3 in all applications?

A: The EN3C6MX substitutes the 1877846-3 only when application operating temperatures remain within -40°C to 65°C and voltage requirements do not exceed 250VAC/DC. Applications requiring the full -50°C to 170°C temperature range or 300VAC rating require the primary 1877846-3 part. The fastening mechanism differs (bayonet lock versus latch lock), requiring mechanical interface verification.

Q: What is the significance of the different fastening types?

A: The 1877846-3 uses latch lock fastening, while the EN3C6MX uses bayonet lock fastening. These represent different mechanical coupling methods and are not interchangeable without redesign of the mating connector interface. Fastening type selection depends on the receptacle connector design in the application.

Q: Are the Switchcraft EN3 series connectors suitable for medical applications?

A: The EN3C6MX and EN3L6MX are listed for general purpose, instrumentation, marine, and medical applications. Both parts carry ROHS3 compliance and unlimited MSL rating. Medical application suitability depends on specific device requirements and regulatory pathway; component selection should be confirmed against device design specifications and applicable medical device standards.

Q: What is the difference between the EN3C6MX and EN3L6MX?

A: The EN3C6MX is a plug connector with male pins, while the EN3L6MX is a receptacle connector with male pins. These represent opposite mating interfaces. The EN3C6MX substitutes the 1877846-3 plug configuration. The EN3L6MX would be used in applications requiring a receptacle interface and is not a direct substitute for the plug-type 1877846-3.

Q: How do the current and voltage ratings compare?

A: The 1877846-3 is rated for 6A at 300VAC. The EN3C6MX and EN3L6MX are each rated for 7.5A at 250VAC/DC. The Switchcraft parts provide higher current capacity but lower voltage rating. For applications operating at 6A or less and 250VAC or less, the Switchcraft parts meet or exceed the electrical requirements.

Q: What packaging differences exist between these parts?

A: The 1877846-3 is supplied in unspecified packaging with 953 pieces in current inventory. The EN3C6MX and EN3L6MX are supplied in bulk packaging with 2649 and 2840 pieces respectively in current inventory. Packaging format should be confirmed with supplier documentation for procurement and assembly requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The 1877846-3 is RoHS Compliant. The EN3C6MX and EN3L6MX are ROHS3 Compliant. Both compliance levels satisfy RoHS directive requirements. REACH status differs: the 1877846-3 lists vendor undefined status, while the Switchcraft parts are REACH Unaffected.
