Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 6-1877846-2 are identified based on the following critical parameters that determine functional equivalency:

Primary Matching Criteria:

• Connector type classification (Plug, Male Pins)
• Position count (6 positions)
• Termination method (Solder Cup)
• Contact finish material (Gold plating)
• Mounting configuration (Free Hanging, In-Line)

Secondary Compatibility Parameters:

• Current rating capacity (minimum 6A required)
• Voltage rating (minimum 300VAC required)
• Operating temperature range overlap
• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part EN3C6MX from Switchcraft Inc. meets the primary matching criteria for connector type, position count, termination method, and contact finish. Differences in fastening type (Bayonet Lock versus Latch Lock), orientation specification, and operating temperature range represent design variations that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 6-1877846-2 and Switchcraft Inc. EN3C6MX connectors are Active products with RoHS compliance certifications. The primary selection criteria should be based on application-specific requirements:

TE Connectivity 6-1877846-2 Selection Factors:

• Extended operating temperature range (-50°C to 170°C) required for high-temperature applications
• Latch Lock fastening mechanism specified in design
• 300VAC voltage rating requirement
• Medical CPC series designation for medical device applications

Switchcraft Inc. EN3C6MX Selection Factors:

• Higher current rating capacity (7.5A versus 6A)
• Bayonet Lock fastening mechanism for quick-disconnect applications
• IP66/IP68 ingress protection rating for environmental sealing requirements
• Broader application scope (General Purpose, Instrumentation, Marine, Medical)
• REACH Unaffected status for regulatory compliance documentation

Both parts maintain MSL 1 (Unlimited) moisture sensitivity and use copper alloy contacts with gold plating. The choice between these connectors depends on whether the application requires the extended temperature range and specific fastening mechanism of the TE Connectivity part, or the enhanced environmental protection and higher current capacity of the Switchcraft part.

Frequently Asked Questions (FAQ)

Q: Can the EN3C6MX directly replace the 6-1877846-2 in all applications?

A: The EN3C6MX meets the core electrical and mechanical requirements (6 positions, solder cup termination, gold-plated contacts, male pins). However, the operating temperature range differs significantly (-40°C to 65°C for EN3C6MX versus -50°C to 170°C for 6-1877846-2). Applications requiring operation above 65°C or below -40°C require the TE Connectivity part. Additionally, the fastening mechanism differs (Bayonet Lock versus Latch Lock), which affects mechanical interface compatibility.

Q: What are the key electrical compatibility parameters?

A: Both connectors support 6-position configurations with solder cup termination and gold contact finish. The EN3C6MX provides higher current capacity (7.5A) compared to the 6-1877846-2 (6A), making it suitable for higher-power applications. The voltage ratings differ: 6-1877846-2 is rated 300VAC, while EN3C6MX is rated 250VAC/DC. Applications requiring 300VAC operation must use the TE Connectivity part.

Q: Are there packaging or inventory considerations?

A: The 6-1877846-2 is available in 840 pieces with new original stock status. The EN3C6MX is available in 2649 pieces with bulk packaging. Inventory availability may influence procurement decisions for high-volume applications.

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

A: The 6-1877846-2 uses Latch Lock fastening, while the EN3C6MX uses Bayonet Lock fastening. These are mechanically distinct connection mechanisms. Latch Lock provides a push-to-connect interface, while Bayonet Lock requires a twist-to-lock motion. The mating connector must be designed for the corresponding fastening type; substitution requires verification of mating connector compatibility.

Q: How do the operating temperature ranges affect substitution?

A: The 6-1877846-2 operates from -50°C to 170°C, while the EN3C6MX operates from -40°C to 65°C. The TE Connectivity part is suitable for high-temperature applications (above 65°C) and extreme cold environments (below -40°C). The Switchcraft part is limited to moderate temperature ranges. Application temperature requirements determine which connector is appropriate.

Q: What compliance certifications should be verified?

A: Both parts are RoHS compliant (6-1877846-2 is RoHS Compliant; EN3C6MX is ROHS3 Compliant). The EN3C6MX has REACH Unaffected status, while the 6-1877846-2 has Vendor Undefined REACH status. For applications requiring REACH compliance documentation, the EN3C6MX provides clearer regulatory status. Both parts have MSL 1 (Unlimited) moisture sensitivity.

Q: What is the cable opening specification and why does it matter?

A: The 6-1877846-2 accepts cable diameters of 0.157" to 0.205" (4.00mm to 5.20mm), while the EN3C6MX accepts 0.160" to 0.265" (4.06mm to 6.73mm). The EN3C6MX accommodates a wider range of cable sizes. Cable diameter compatibility must be verified during substitution to ensure proper solder cup engagement and strain relief.
