Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-1877846-4 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Connector type: Plug with male pins
• Position count: 6 positions
• Termination method: Solder cup
• Contact finish: Gold plating
• Mounting configuration: Free hanging in-line

Electrical Compatibility Parameters:

• Current rating capability
• Voltage rating specification
• Operating temperature range
• Contact material composition

The Switchcraft Inc. EN3C6MX meets the core functional requirements as a 6-position circular connector plug with male pins, gold-plated contacts, and solder cup termination. Substitution is valid where the electrical and mechanical parameters of the substitute part satisfy or exceed the application requirements of the primary part.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 4-1877846-4 is the primary specification for applications requiring:

• Extended operating temperature range (-50°C to 170°C)
• Medical device applications with established design history
• Latch lock fastening mechanism
• 300VAC voltage rating

Switchcraft EN3C6MX is a valid substitute where:

• Higher current capacity (7.5A vs. 6A) is beneficial
• Operating temperature range of -40°C to 65°C is acceptable
• Ingress protection rating (IP66/IP68) is required
• Bayonet lock fastening is compatible with the application
• ROHS3 compliance is specified

Both parts maintain RoHS compliance and identical ECCN/HTSUS classifications. The substitute part provides enhanced environmental protection and increased current handling capability. Selection between these parts depends on specific application requirements regarding temperature range, fastening mechanism, and ingress protection needs.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft EN3C6MX directly replace the TE Connectivity 4-1877846-4 in all applications?

A: Direct replacement is valid where the operating temperature range of -40°C to 65°C is acceptable for the application. The TE Connectivity part supports extended temperature operation to 170°C, which the Switchcraft substitute does not. Fastening mechanism differences (latch lock vs. bayonet lock) must also be evaluated for mechanical compatibility.

Q: What are the key electrical differences between these two 6-position connector plugs?

A: The TE Connectivity 4-1877846-4 is rated for 6A at 300VAC. The Switchcraft EN3C6MX is rated for 7.5A at 250VAC/DC. Both use gold-plated copper alloy contacts. The Switchcraft part provides higher current capacity but lower voltage rating and narrower temperature range.

Q: Are both parts suitable for medical device applications?

A: The TE Connectivity 4-1877846-4 is specified for medical applications. The Switchcraft EN3C6MX lists medical as one of multiple application categories alongside general purpose, instrumentation, and marine applications. Application suitability depends on specific medical device requirements and regulatory pathway.

Q: What is the difference in cable opening specifications?

A: The TE Connectivity part accepts cable diameters of 0.157" to 0.205" (4.00mm to 5.20mm). The Switchcraft part accepts 0.160" to 0.265" (4.06mm to 6.73mm), providing a wider range of compatible cable sizes.

Q: Do both connectors have the same ingress protection rating?

A: The TE Connectivity 4-1877846-4 does not specify an ingress protection rating. The Switchcraft EN3C6MX is rated IP66/IP68, providing dust-tight and waterproof protection. This is a significant difference for applications requiring environmental sealing.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 4-1877846-4 packaging is not specified in the available data. The Switchcraft EN3C6MX is supplied in bulk packaging. Packaging format may affect procurement and handling procedures.

Q: What fastening mechanism differences exist between these connectors?

A: The TE Connectivity 4-1877846-4 uses a latch lock fastening type. The Switchcraft EN3C6MX uses a bayonet lock fastening type. These are mechanically distinct coupling methods and are not interchangeable without mating connector modification.
